Main Sexuality and Fetishes
Monster Girls, Nonhuman Girls, Demon Girls
From the animal-eared and tailed beast girls to the snake-bodied lamia and the spider-bodied arachne, there is always something new and exciting to be discovered. The "Monster Girl Encyclopedia" is a catalog of mainly non-human girls, including witches, vampires, and other girls who look no different from normal humans.
Monster Girl x Human Male
The monsters in the world of "Monster Girl Encyclopedia" are all female, and under the influence of a Succubus, the mamono lord, they have the nature of inma. They instinctively seek sex with human men as mates to provide them with sperm for sustenance and to produce offspring. In other words, all of the monster girls in this setting are sexually active. They all do naughty things with human men as their mates.
Reverse Rape
Monster girls are so eager to have human men as mates and companions they often try to win a man by forcing him to do sex with them, often in the form of reverse rape. Although they do perform semen-sucking (energy sucking) sex, they never suck a man to death, and there is no element of eating him afterwards.
Seduction
The "Monster Girl Encyclopedia" is mainly light femdom oriented, but some of the monster girls are a race or individual that seduces human men to become their mates, and tries to get them to rape them themselves. Men who are seduced by them will never be able to let them go again.
Erotic Sexual Relationship
This is the end result of a human male who has been with a monster girl through reverse rape or seduction. They will spend their days having sex with her as her husband. The monster girl who got a mate pours all her love, lust, and sexual desire into her husband only, and it leads to a flirtatious and erotic sex life.
Monsterization
A human girl can be turned into a monster by being attacked by a monster girl or by eating food that contains magical power. The monsterized girl's personality and memories remain the same as when she was a human, but the desires and instincts of a monster sprout, and she becomes a very erotic monster girl. The girl who has become a monster girl becomes a beautiful and bewitching being, seducing that person she loves and turning him into her own thing (husband). The childhood friend who could not express her feelings for the man she loves, she rapes him in reverse and makes him her husband, while making a naughty face. They become more comfortable doing such things. It is not a depraved act. There are no elements of NTR or killing people close to you by becoming a monster.
Special fetishes that may be chosen by the audience. These are not the main fetishes, but are ones that may also be chosen.
Harem
The "Monster Girl Encyclopedia" is basically a one-on-one relationship between a monster girl and a human man.
There are some races where multiple monsters marry one man, and sometimes a man who tries hard in various ways can be liked by many monster girls. A harem may be formed with one man and several monster girls. There are no losing heroines.
TS
Human males who have the desire to become female or have fallen in love with someone of the same gender, they may undergo a sex change and become monster girls. After becoming a monster girl, she will mate with the man she fell in love with as a monster girl and lead an erotic sex life.
Transformation, Tentacles
Some monsters temporarily transform their husbands into beasts, monsters, or tentacles to enjoy sex. In other words, as part of the monster girl x human guy play, the monster or tentacle that rapes the monster girl is her husband.
×Sexuality and fetishes that we do not deal with x
We are sorry. If you like these fetishes, you may be offended.
NTR
We do not deal with both cuckolding and being cuckolded, nor do we deal with similar proclivities or their derivations. In addition, the secondary creation (doujin works) policy of this content also prohibits secondary creation in this genre. We would appreciate it if you could refrain from visiting our site if you are even a little bit fond of this fetish, as you may be offended by it. We ask for your cooperation in making a clear distinction between the two genres.

図鑑世界まめちしき：図鑑世界で生まれる人間の男女比は男性の方が多いらしいぞ！魔物娘じゃない昔の魔物との戦いや人間同士での戦で命を落とすのは、やっぱり女性より男性の方が多かったためか、自然とそうなっていったらしいです。生物のちからってすごい！
A tidbit of knowledge about the encyclopedia world: As for the sex ratio of humans born in the encyclopedia world, it seems there are more men! Of course, when fighting wars with the monsters of old who were not monster girls, or fighting against fellow humans, more men lost their lives than women, and perhaps for that reason, it seems the birth rate has naturally adjusted in that manner. The power of living things is incredible!
図鑑世界まめちしき：そして、魔物が魔物娘になったり、海難事故を起こしていたポセイドンがストライキしたりして男性の死亡数が減った今でも出生比率はそのままなので、人間の間ではすごい男余りなのだ。そしてあぶれた男をゲットできるので魔物娘は大喜びなのだ。やったぜ！
A tidbit of knowledge about the encyclopedia world: And even now that the number of men dying has decreased since monsters became monster girls and Poseidon, who used to cause shipwrecks, went on strike, the birth ratio is still the same, so there's an incredible surplus of men among humans. And the monster girls are overjoyed that they're able to get those left out men. Whoopee!
* There are still parts of the ocean controlled by gods allied with the Chief God (though these areas are small relative to what Poseidon controls). Humans are largely safe from monster attacks in such places but unlike where Poseidon reigns they can die from storms and such. (source: Kenkou’s Japanese Q and A).
* Even in the current time of the setting its not unusual for commoners in anti-monster lands to spend their whole lives without ever meeting a monster (assuming they remain in their village). The average person in such a land thus knows fairly little about monsters due to the flow of information being slow and sometimes restricted to what the Order approves of.

* Only monsters being born from human/monster coupling is not a "new" thing but a holdover from the age of the former mamono lords, wherein any monsters that could breed with humans still only produced monsters (source: Kenkou’s Japanese Q and A).
* In the current MGE, revealing outfits are common among human women due to habituation. Monsters tend to wear very revealing outfits, and humans seeing this will consider moderately revealing things proper as they are still “less” revealing than what the monsters wear. Monsters disguised as humans also bring mamono-style clothing into places where monsters are barred, and over time influence clothes makers. (source: Patreon Q and A).
* In the MGE it's impossible for two men to love one women completely equally, so cases of a woman monsterizing and being torn between two men who want her won't happen. If the man she doesn't choose is genuinely heartbroken over it, chances are a doppelganger or other monster girl will come in to comfort him. (source: Patreon Q and A).
* A good job for a man who wants to travel around the world of the MGE is to be a peddler, as one can make a good amount of money selling various unique items from tourist attractions in places where they are not normally available. Working for a ratatoskr publishing house as a reporter or in a Runya Runya Sabbath doing research for a book on tourist attractions or regional cuisine are other options. (source: Patreon Q and A).

There were cases of humans who turned into monsters, but this was normally a vicious human-murderer losing their reason and becoming a beast in mind and body.

Spoiler
** The most widely used language among both humans and monsters is the "Chief Deity Language," which is said to have been brought to humans by the chief deity. Since many monsters did not possess any language in the previous era, when they became monster girls they often took on the main language the humans used. This language is good for telling stories and writing poetry, and most literary works by monsters and humans alike are written in this language. While this is the main human language, cultures where the influence of the Order has been weak through history (such as the Mist Continent and Zipangu), have their own, distinct, languages. There are also races that have their own language but also use the Chief Deity language as an additional official language, such as elvish for elves and dwarvish for dwarves.
** There is also a genuine "Monster Language" that has been spoken among the higher rank monsters since ancient times. It is known for its directness compared to the theistic language of the chief deity, and for having many words that express complex things with a single word. It is thus very suitable for casting magic. This language historically was limited to certain intelligent monster races, such as demons, succubi, vampires and baphomets, and upon gaining sapience in the current era most monsters adopted the chief deity language as it was easier to communicate with humans using this than the monster language, and many monsters that did speak the language gave it up in favor of the chief deity language. However, even in the present some specialized Sabbath grimoires are written in this language, and there are many high rank monsters that can speak the monster language. Further, because most monsters that did speak in the previous era still rarely communicated or cooperated with other types of monsters, subtle differences in the monster language developed between races that humans would define as dialects. These include:
1. The "Standard Language" is used by demons, baphomets and witches. It is the most formal and easy to use.
2. The "Inma's Language" contains many words with lewd meanings and tends to be naturally lascivious and seductive.
3. The "Vampire Language" has many commanding words and tends to be pronounced in a overbearing tone.
** Lastly, there is an "Abyssal Language" spoken by some monsters that live in the deep sea. It is completely different from the other monster language.

* As has been mentioned previously, Druella's personality is very much influenced by both her parents. The Mamono Lord could be said to be rather mild-mannered and meticulous, while her husband is more rough and direct. For an example, if the pair faced a bandit fort full of traps, the mamono lord would prepare a great deal in advance, examining enemy numbers and how to neutralize the traps. Her husband, prioritizing taking action, would be likely to rush in, smash the traps and beat the bandits into submission as quickly as he can. (source: Personal communication with KC).
* Enma was born during one of many honeymoons the mamono lord and her husband have had (it's not know what number this one was). The honeymoon was in Zipangu, and Enma was born and raised there. This caused her to be greatly influenced by the cultural styles and values of Zipangu. Lilim rooted in specific places like this often have values and aesthetics associated with those places. This does not mean there is a lilim for every part of the world though, as there are only so many lilim. (source: Subscribestar reply)

* The distinction between hard yuri and the sexual behavior monster girls engage in with other females works like this from their perspective. Namely it is about intention. Monsters don't seek sexual satisfaction from each other or from human women, to them what they do with other females is either for the purpose of monsterization or amounts to playing or showing affection among intimate friends; satisfaction is something they only seek from the man they bond with as their husband. They may also engage in sexual behavior with their own kind as a extra means of luring a man (as in the liliraune). (source: Kenkou's 2015 Ask.fm page, viewable on the Setting" topic on the Q&A board, liliraune profile).
* While monsters often have particular work they are notably skilled at, they will often also assist in whatever job/work their husband happens to have. (source: Kenkou’s Japanese Q and A).
* In more detail regarding what men monsters don't like, they won't fall in love with psychopaths and wicked people who think things like "killing people is fun" or "causing others misfortune is fun." (source: Kenkou’s Japanese Q and A).
* Monsters that seek strong husbands will still prioritize a weak man who challenges them provided he has feelings for them, and thus will reject other men. A childhood friend will also get priority if such feelings are present. As monsters live long lives and often have a leisurely sense of time, it’s not unusual for them to start having sex with him even before the man gets strong enough, as they know the man will become strong eventually. Basically he doesn't need to be powerful in the present, and they will mold him into a powerful man. (source: Patreon Q and A).
* In addition to playing various sports themselves, many monsters enjoy watching their boyfriends and husbands play sports and will cheer them on. They may wear various outfits similar to cheerleading outfits from our world. (source: Patreon Q and A).
* Among the holidays commonly celebrated by monsters is the famous "Anniversary of the Ascension of the Mamono Lord." It celebrates the gaining of the bodies monsters now have, and their gratitude to her for it. It’s widely considered a day to dress in special revealing outfits to show off those bodies. (source: Patreon Q and A).
* Many monsters are aroused at the sight of a weak man. However, this is rarely mentioned in the profiles as a distinct fetish since compared to monster girls most men are weak anyway. "I want to be protected by you" and similar words are seen as a strong confession of love, especially by monsters like hellhounds, ocelomeh and amazoness. (source: Patreon Q and A).
* Pandemonium trades with the outside world and has stores in it. However, due to the extremely desired-focused nature of Pandemonium's residents, the stores are often only open a few hours a day once a week. Yet, due to the distorted nature of time in Pandemonium, if one enters the store then regardless of what time it is in the regular world, the store will always be connected to a time in Pandemonium when the store is open. (source: Patreon Q and A).
* Aside from using a mana marker on yourself (it is noted this is not difficult magic to learn), it is possible to find a eligible monster of a race you want by simply shouting out the kind you want where monster girls are around. If you are serious then a friendly monster girl may be able to introduce you to a friend of acquaintance of that kind of monster. A more reliable way is to go to agencies that exist in some cities that are run by monster girls. These agencies work to match up unmarried men with specific monster girl types. (source: Patreon Q and A).
* Monsters consider sex toys their husband uses alone, masturbation supplies, etc. to be acceptable, though jealous types like shirohebi may get jittery about it. They will of course want him to do it with them instead if he is able to. (source: Kenkou's 2015 Ask.fm page).
* Natural born monsters don't really have complexes about their age, since they look young regardless. However, monsterized humans may feel differently and have that human potential stigma toward their own age. Saphirette, for instance, intentionally obscured her birth date in World Guide 2 in order to keep her age from being known, as she has a complex over how she is an adult with no experience in romance. (source: Personal communication with Kenkou Cross).
* Much like their taste in other clothes, monster wedding dresses may be revealing or modest depending on the individual and the desires/tastes of her husband. One reason to wear a modest dress is to encourage her husband to take it off. (source: Patreon reply).
* Related to how what is most important to monsters is not who is "in charge" during sex but the fact that they are having sex with their husband, and they can be happy with both extremes. Monsters have long marital sex lives, and want to enjoy all sorts of things with their husband. Thus, even if its not their favorite position or type of erotic play, they still may indulge in it at times. (source: Making of Ocelomeh article on Patreon).
* After the Mamono Lord achieves her goals, there will be fewer monsters who "attack men to get their hands on them" than before, simply because more monsters will live in cities and be able to seduce humans in other ways. That said, the instinct of "attacking because they cannot suppress their lust" is a separate instinct from the "monsters attack humans" instinct, so the former will remain unchanged and many monsters will continue to attack men in order to be with them or because they feel so much love. Further, it seems the "monsters are higher ranking creatures than humans" setting will in a sense never be able to be completely removed even when the Mamono Lord's plans are realized. In short, in the fully changed settings where the barrier between humans and monsters has been erased, "monsters attack humans" as a instinct will indeed disappear, but it will be replaced with common sense and values that say "if a girl likes a boy enough, she will attack the boy." (source: Personal communication with Kenkou Cross).
* Further, monsters like amazoness may still go on hunting trips for men, they just will be more likely to bond with male childhood friends instead. (source: Personal communication with Kenkou Cross).
* Regarding ruler type monsters without kingdoms, such as the children of ruling titania or pharaoh, they do naturally have a strong drive and aptitude toward governing local communities. When they grow up they may help their mothers (or fathers) govern as part of the existing kingdom, or they may go out and start new kingdoms. However, this is not such a strong drive that they feel impatient about it or unfulfilled if they don't do it. So it is common for them to take other paths in life. For two examples:
1. A titania, interested in the development of magical tools, becoming a researcher.
2. A pharaoh, interested in art, being content in her small atelier.
However, even in those cases, their leadership qualities can blossom. The titania still became the head of the research team and gets treated like everyone's big sister. The pharaoh artist may well get a kingdom for herself created by her many fans who are fascinated by both her works and herself. (source: Personal communication with KC).
* Due to different standards for sexiness and sexuality, men don't tend to wear skimpy outfits, and there are no monsters that demand this. It is not that monsters consider men in skimpy attire unattractive, but for monster girls the appeal of their husbands is most strongly stimulated by their words, gestures and scent. (source: Personal communication with KC).
* While some monsters take competitions very seriously, most are quite whimsical. To combat this, the "Husbands Union" (which includes many managers and promoters of monster girl athletes) established a sports culture where monsters who win a match can do whatever they want to their husband, hoping it would motivate them. However, the players themselves added to this culture with the rule of "punishment sex with the husband" if they lose a match, so in the end the whimsical nature of the monster's interest in the sport remained. (source: KC tweet).
* Sap from the Treasured Child Tree is an ideal first place prize for monster girl sports tournaments, however, since the sap does not keep for long once it leaves the tree, making this work required cooperation with the tentacle forest. The result was tournaments "sponsored" by the forest, where first place winners are allowed by the forest to spend a week's vacation at a resort house next to the Treasured Child Tree and are allowed all the sap they want for that time. In return, losing players are subjected to a week of punishment sex with their tentacle-transformed husbands, compensating the forest with all the mana produced by this sex. (source: KC tweet).
* Popular sports among monster girls include martial arts and gladiatorial combat, but there are also ball games similar to soccer (but with aerial matches for flying monsters as well), and various races where the husband rides on the wife's back. These races include centaur races, and dragon-rider races of various kinds. (source: KC tweet).
* While it is not as popular a topic as studying the current monsters (and any researcher who takes a positive view of monsters will end up a wanted man by the Order, and married to a monster if he is not married already, so it can be a tough job) there some human scholars who study the monsters of the former mamono lord's era, as well as monsters who study their former selves. Hearsay from monsters still alive from that time, and various records left of battles between ancient heroes and mamono lords make it a worthy topic of study. That said, in terms of casual conversation, most monsters do not like to talk about that era. Interestingly, this applies to monsters born in the current era as well, making it an instinctive dislike. (source: Personal communication with KC)
* When it comes to actual memories, they can be hard to come by. Most monsters living today were born after the old era ended, and most monsters from the previous era lacked intelligence and strong ego/self awareness at the time and so remember little of it. As for those who did have intelligence and firm egos back then (such as baphomets), they remember more clearly, and feel strong remorse over the things they did back then. It is something the husband of such a monster must do their best to comfort and support them over. (source: Personal communication with KC)
* While you are in theory supposed to take on a juvenile form when joining a Sabbath, in practice the criteria for acceptance into a specific Sabbath varies from one to the next. Often a girl will be accepted even if she is not flat-chested, so long as she is or becomes lolita in other aspects. Further, the Greilia and Runya Runya Sabbaths have some members who are outright adult women in appearance, as their focuses prioritize things other than being loli. (source: Subscribestar reply)
A monster's sense of aesthetics and beauty
* While monsters often have particular work they are notably skilled at, they will often also assist in whatever job/work their husband happens to have. (source: Kenkou’s Japanese Q and A).
* In more detail regarding what men monsters don't like, they won't fall in love with psychopaths and wicked people who think things like "killing people is fun" or "causing others misfortune is fun." (source: Kenkou’s Japanese Q and A).
* Monsters that seek strong husbands will still prioritize a weak man who challenges them provided he has feelings for them, and thus will reject other men. A childhood friend will also get priority if such feelings are present. As monsters live long lives and often have a leisurely sense of time, it’s not unusual for them to start having sex with him even before the man gets strong enough, as they know the man will become strong eventually. Basically he doesn't need to be powerful in the present, and they will mold him into a powerful man. (source: Patreon Q and A).
* In addition to playing various sports themselves, many monsters enjoy watching their boyfriends and husbands play sports and will cheer them on. They may wear various outfits similar to cheerleading outfits from our world. (source: Patreon Q and A).
* Among the holidays commonly celebrated by monsters is the famous "Anniversary of the Ascension of the Mamono Lord." It celebrates the gaining of the bodies monsters now have, and their gratitude to her for it. It’s widely considered a day to dress in special revealing outfits to show off those bodies. (source: Patreon Q and A).
* Many monsters are aroused at the sight of a weak man. However, this is rarely mentioned in the profiles as a distinct fetish since compared to monster girls most men are weak anyway. "I want to be protected by you" and similar words are seen as a strong confession of love, especially by monsters like hellhounds, ocelomeh and amazoness. (source: Patreon Q and A).
* Pandemonium trades with the outside world and has stores in it. However, due to the extremely desired-focused nature of Pandemonium's residents, the stores are often only open a few hours a day once a week. Yet, due to the distorted nature of time in Pandemonium, if one enters the store then regardless of what time it is in the regular world, the store will always be connected to a time in Pandemonium when the store is open. (source: Patreon Q and A).
* Aside from using a mana marker on yourself (it is noted this is not difficult magic to learn), it is possible to find a eligible monster of a race you want by simply shouting out the kind you want where monster girls are around. If you are serious then a friendly monster girl may be able to introduce you to a friend of acquaintance of that kind of monster. A more reliable way is to go to agencies that exist in some cities that are run by monster girls. These agencies work to match up unmarried men with specific monster girl types. (source: Patreon Q and A).
* Monsters consider sex toys their husband uses alone, masturbation supplies, etc. to be acceptable, though jealous types like shirohebi may get jittery about it. They will of course want him to do it with them instead if he is able to. (source: Kenkou's 2015 Ask.fm page).
* Natural born monsters don't really have complexes about their age, since they look young regardless. However, monsterized humans may feel differently and have that human potential stigma toward their own age. Saphirette, for instance, intentionally obscured her birth date in World Guide 2 in order to keep her age from being known, as she has a complex over how she is an adult with no experience in romance. (source: Personal communication with Kenkou Cross).
* Much like their taste in other clothes, monster wedding dresses may be revealing or modest depending on the individual and the desires/tastes of her husband. One reason to wear a modest dress is to encourage her husband to take it off. (source: Patreon reply).
* Related to how what is most important to monsters is not who is "in charge" during sex but the fact that they are having sex with their husband, and they can be happy with both extremes. Monsters have long marital sex lives, and want to enjoy all sorts of things with their husband. Thus, even if its not their favorite position or type of erotic play, they still may indulge in it at times. (source: Making of Ocelomeh article on Patreon).
* After the Mamono Lord achieves her goals, there will be fewer monsters who "attack men to get their hands on them" than before, simply because more monsters will live in cities and be able to seduce humans in other ways. That said, the instinct of "attacking because they cannot suppress their lust" is a separate instinct from the "monsters attack humans" instinct, so the former will remain unchanged and many monsters will continue to attack men in order to be with them or because they feel so much love. Further, it seems the "monsters are higher ranking creatures than humans" setting will in a sense never be able to be completely removed even when the Mamono Lord's plans are realized. In short, in the fully changed settings where the barrier between humans and monsters has been erased, "monsters attack humans" as a instinct will indeed disappear, but it will be replaced with common sense and values that say "if a girl likes a boy enough, she will attack the boy." (source: Personal communication with Kenkou Cross).
* Further, monsters like amazoness may still go on hunting trips for men, they just will be more likely to bond with male childhood friends instead. (source: Personal communication with Kenkou Cross).
* Regarding ruler type monsters without kingdoms, such as the children of ruling titania or pharaoh, they do naturally have a strong drive and aptitude toward governing local communities. When they grow up they may help their mothers (or fathers) govern as part of the existing kingdom, or they may go out and start new kingdoms. However, this is not such a strong drive that they feel impatient about it or unfulfilled if they don't do it. So it is common for them to take other paths in life. For two examples:
1. A titania, interested in the development of magical tools, becoming a researcher.
2. A pharaoh, interested in art, being content in her small atelier.
However, even in those cases, their leadership qualities can blossom. The titania still became the head of the research team and gets treated like everyone's big sister. The pharaoh artist may well get a kingdom for herself created by her many fans who are fascinated by both her works and herself. (source: Personal communication with KC).
* Due to different standards for sexiness and sexuality, men don't tend to wear skimpy outfits, and there are no monsters that demand this. It is not that monsters consider men in skimpy attire unattractive, but for monster girls the appeal of their husbands is most strongly stimulated by their words, gestures and scent. (source: Personal communication with KC).
* While some monsters take competitions very seriously, most are quite whimsical. To combat this, the "Husbands Union" (which includes many managers and promoters of monster girl athletes) established a sports culture where monsters who win a match can do whatever they want to their husband, hoping it would motivate them. However, the players themselves added to this culture with the rule of "punishment sex with the husband" if they lose a match, so in the end the whimsical nature of the monster's interest in the sport remained. (source: KC tweet).
* Sap from the Treasured Child Tree is an ideal first place prize for monster girl sports tournaments, however, since the sap does not keep for long once it leaves the tree, making this work required cooperation with the tentacle forest. The result was tournaments "sponsored" by the forest, where first place winners are allowed by the forest to spend a week's vacation at a resort house next to the Treasured Child Tree and are allowed all the sap they want for that time. In return, losing players are subjected to a week of punishment sex with their tentacle-transformed husbands, compensating the forest with all the mana produced by this sex. (source: KC tweet).
* Popular sports among monster girls include martial arts and gladiatorial combat, but there are also ball games similar to soccer (but with aerial matches for flying monsters as well), and various races where the husband rides on the wife's back. These races include centaur races, and dragon-rider races of various kinds. (source: KC tweet).
* While it is not as popular a topic as studying the current monsters (and any researcher who takes a positive view of monsters will end up a wanted man by the Order, and married to a monster if he is not married already, so it can be a tough job) there some human scholars who study the monsters of the former mamono lord's era, as well as monsters who study their former selves. Hearsay from monsters still alive from that time, and various records left of battles between ancient heroes and mamono lords make it a worthy topic of study. That said, in terms of casual conversation, most monsters do not like to talk about that era. Interestingly, this applies to monsters born in the current era as well, making it an instinctive dislike. (source: Personal communication with KC)
* When it comes to actual memories, they can be hard to come by. Most monsters living today were born after the old era ended, and most monsters from the previous era lacked intelligence and strong ego/self awareness at the time and so remember little of it. As for those who did have intelligence and firm egos back then (such as baphomets), they remember more clearly, and feel strong remorse over the things they did back then. It is something the husband of such a monster must do their best to comfort and support them over. (source: Personal communication with KC)
* While you are in theory supposed to take on a juvenile form when joining a Sabbath, in practice the criteria for acceptance into a specific Sabbath varies from one to the next. Often a girl will be accepted even if she is not flat-chested, so long as she is or becomes lolita in other aspects. Further, the Greilia and Runya Runya Sabbaths have some members who are outright adult women in appearance, as their focuses prioritize things other than being loli. (source: Subscribestar reply)
A monster's sense of aesthetics and beauty
Spoiler
While monsters can certainly distinguish what humans would regard as beautiful or ugly, they pay no real mind to it. Instead they make judgments based on the emotions and nature they are able to see in someone's facial features. They understand attractive looks and attracting the opposite sex even better than humans do but their values over this manifest differently.
When looking at a woman they judge her beauty or ugliness based on how well she can captivate her prey, and when monsterizing her they do not see it as making a ugly woman beautiful but rather enhancing her ability to captivate men.
When they enhance their husband's appearance (if he is indifferent to his looks) they do not do so with the intent of making him "more handsome" but rather "more impressive", or more socially favorable.
Further, while monsters can make judgments regarding a man as being "tall and cool" or "short and cute," these do not relate to them having any innate preferences for these features. For instance there are not monsters that simply "like muscular men." Instead, if they fall for a muscular man they are attracted to the daily effort those muscles represent. A monster that falls for a short boy will find his earnest efforts to compensate for the physical limitation attractive.
In accordance with this, they are passionate about helping raise their husband up to have the body and appearance they mutually desire. However, it is inappropriate to compare this to them seeking to perfect him or personally "build" him. This is in part due to their perspectives on time owing to their long lives. For an example, to a baphomet the man she chooses as her partner holds the same value whether he is someone who has spent 10 years to become a hero or who will spend 10 years to become a hero. She would equally cherish the 10 years of effort he made before they met as she would the 10 years she would spend nurturing his abilities. Further, if he cannot become a hero in 10 years due to lack of talent, then she can still make him her husband and they can work together to achieve hero status in another 100 or 1000 years. It makes little difference to her.
When it comes to objective viewpoints, they can perfectly assess that a face is judged as ugly or beautiful in human society, but to them that is just observing and stating a fact. It has no bearing on what will specifically arouse them or what they judge as attractive. To them the man they recognize as their husband is the most attractive male and in a unique, incomparable way. They feel attraction and desire based on the unique "identifying elements" that make up his being. They have a romantic sentiment "the person you fall in love with looks good to you!"
Indeed, it can be said monsters are able to see a person's inner being through their outer appearance. When a satyros says "your smile is wonderful" as a pickup line, she is referring to what she sees within the smile more than the smile itself, and how their life experiences have shaped that smile. It could be said monsters have no interest in the face on its own beyond using it for individual identification. (source: Personal communication with KC)

* Those who wish to avoid their monster girl daughters falling in love with them are recommended to encourage their independence. Outside of monsters where incest is cultural or instinctive, incest usually occurs only if the father pampers the daughter too much and spends time with her to the extent that she doesn't get enough time with others.(source: Kenkou’s Japanese Q and A combined with info from World Guide 1: Monster Ecology 7).
Additionally, if the wife genuinely does not want it then incest will not happen. The daughter will sense her mother's devotion and never develop such feelings for her father to begin with. (source: Patreon comment from KC).
The majority of marriages between men and monsters in the MGE are monogamous. While he does like harems, the main reason KC has harems in the setting is to make it so there are not any heroines who love a hero but lose him to someone else and never have their feelings fulfilled. The hero is obligated to make all the heroines happy. (source: Patreon comment from KC).
* For men with harems, there exist various magical options to ease issues of spending enough time with individual wives. These magics deal with perception of time, slowing down time, etc. However, even if the man or monsters lack such magic, Pandemonium itself and places such as rooms with the same time freezing properties as Pandemonium can be made that offer a way to go off and have sex as much as one wants with one wife and then come back to the regular world where no time will have passed, so they are not missed by the other wives. (source: Patreon PM from Kenkou).
* For harems involving a member of a race that habitually confines their husband, basically there aren't special rules for how they deal with it, beyond that if he has a single body then obviously the husband can't stay with just the one wife all the time. As is usually the case, what happens will vary with the individuals involved. In some cases the man may only be kept contained when he is interacting with that specific wife. In others there may be frequent use of the doppelganger potion so that an extra body can stay with her all the time. Another thing to note is that monsters like sandworm and will-o-the-wisp have enough space to let another harem member in with them and the husband. (source: Personal communication with Kenkou Cross).
* In real world biology incest causes harm due to the likelihood of related creatures having problematic genes in common, but the genetics of monster girls and humans are very different. Indeed, the mechanisms allowing them to interbreed in the first place and how genetic inheritance works are very different from interbreeding within the same species. There is also the magical aspects to it, such as mamono mana being linked to all other mamono mana via the mamono lord meaning that it has all the information needed to compensate for any loss in genetic diversity.

* The protective effects of mamono mana are automatic, and when it comes to inflicting major damage they cannot be overcome. Humans have tried a number of times to use mamono mana as fuel for deadly spells or magical items, storing the mana via structures similar to mana cages. They always fail, the energy becoming nonlethal. (source: Personal communication with KC)
* The exceptions we see in various information relate to minor damage, and the mechanism is as follows. Namely, if a monster wants to bite or sting her husband, leave a hickey or other mark, then her will to do this overcomes the minute protective mana that would otherwise have interfered. Even then, a protective effect will still activate to prevent infection, such as with vampire bites. Further, monsters that use venom or poison injected via damaging the body have components in the toxin that stop bleeding. However, impossible as it is, if a monster desired to inflict major harm with her mana on a person, the protective effect would take precedence and turn it into a nonlethal spell. (source: Personal communication with KC)
* So then how do we account for monsters using their powers to kill animals, or the Mamono Lord slaughtering the tentacle plants with fire magic and such long ago? It seems to be that the mana regards such uses as equivalent to targeting "raw meat" rather than a living thing. The exact mechanism is unknown, but it seems the criteria for this is whether or not the target of the offensive mana has a soul. Any tentacle plants, for instance tentacle brains, that had formed a soul or were in the process of doing so, would have not been burned up by the fire but had a different effect applied instead. (source: Personal communication with KC)
* Despite the mechanics of mamono mana normally making it impossible for them to do serious harm to, let alone kill, a human, it remains true from the settings books that monsters can and do kill in self defense or defense of their loved ones. This has to do with additional settings and differences regarding when the automatic protection effects of mamono mana are applied, however, at the present time KC does not want to go into further detail on how this works. (source: Personal communication with KC)
Perentie note: To be clear this is pure speculation but to me it sounds like because it is a rule of the encyclopedia world that monsters love humans, the mana of a monster would never cooperate with the desire to hurt a human. However, if a monster girl needed (as opposed to wanted) to kill to protect herself or someone else, the mana may react differently.

* Monsters capable of learning spells can learn the polymorph spell (now officially known as anthropomorphosis and distinct from related shape-changing spells) to assume a human form, though their skill with it varies greatly (they may not be able to change their skin color for instance). This is useful for monsters like alraunes that normally have to move around inside their flower and may find it inconvenient on a date. (source: Kenkou’s Japanese Q and A).
* Pleasure runes work just as well when carved on men. (source: Kenkou’s Japanese Q and A).
* The spell of anthropomorphosis can be used instinctively rather than learned, allowing women who have recently monsterized to hide their changed form. In fact, monsterized humans are often better at using anthropomorphosis than natural born monsters since they were human originally. (source: Patreon PM from Kenkou).
* Divination magic is extremely advanced, and there are few who can see far into the future. Asura Mythra’s case of seeing her husband centuries before meeting him was an exceptional thing. Predicting the relatively near future is more common but still very difficult and not a magic widespread among monsters. There are sabbaths that specialize in the study of divination magic to try to prevent wars and disasters by predicting them, though using it to find husbands is also a priority. (source: Patreon Q and A).
* The doppelganger potion is not magic that increases the number of yourselves, but rather increases the amount of body your singular self has. As such, it takes training to do more than instinctual things with them, as you have to learn how to handle seeing, hearing, etc. multiple things at once. This is why when inexperienced the incubus can't do much other than have sex when using the potion. (source: Kenkou tweet).
* Similar to how Theriomorphosis Potions are created by studying the the mana of mamono realm beasts, there exist abyssal transformation potions capable of temporarily transforming a man into a monstrous form similar to that of the husband of an abyssal monster. These potions have the side effect if used in excess they may induce a permanent secondary evolution in non-abyssal monsters into a type of abyssal monster capable of granting her husband the power to transform. Having spent her childhood living among the abyssal monsters, Asura Mythra may be a related example, a monster that is more than "just" a kraken. (source: Personal communication with KC).

* Being able to take on the form they had in the ancient era is not a power limited among monsters to only dragons, it is simply dragons who are most known for it as they find it easy to do the transformation due to being created to be "the strongest creatures". Baphomets are another race that can easily do this. In truth, any monster that builds up sufficient power can gain access to this transformation magic, with some caveats.
1. While building up power is necessary, there is not a set level of power needed. This is due to how the most important thing is to have a strong image in your head of what the ancient form looked like (gained from learned knowledge, having lived in that time, or other means), or to have instinctive knowledge of this form. Dragons have the latter, baphomets the former (due in part to their high intelligence and high rank as monsters). In contrast, low rank monsters like the large mouse are generally unaware of their ancient form both on an instinctual and intellectual level, and thus transforming into it is often not possible or very difficult for such a monster no matter how powerful they become. In many cases it also varies on an individual level, some monsters are simply good at it while others are not.
2. Monsters that did not exist in the ancient era, such as holstaurs and jabberwocks, don't have a ancient form of their current selves. However, because they are descended from minotaurs and dragons, they can use that ancient form if they transform (easy for a jabberwock, potentially possible for a holstaur).
3. Monsters that looked the same in the ancient era as they do now, such as lamia and succubi, of course have no ancient form to turn into. It may be possible for them to turn into a more monstrous form, but in that case it would just be transformation magic rather than taking on an ancient form.
* As for the ancient form, it's important to note this is not a "super mode." No monster is any stronger when transformed like this, so the uses for the form are more for utility such as providing greater reach, carrying more things, etc. In relation to this, it gives you a further sense of how powerful a monster like a dragon is in that she packs in a serious tail swipe in her human-sized form all the power that the tail of her ancient form has. (source: Personal communication with Kenkou Cross).
* Regarding what it looks like to transform into the ancient form, it varies with the individual. It typically is instant, accompanied by the body being surrounded by bright light, flames, or darkness like that of the dark matter. (source: Personal communication with KC).
* The size of the ancient dragon form varies with individual and race. Notably, the wyvern seen on the cover of the Dragonia book is meant to be a symbolic depiction of the "image" of Dragonia, representing various aspects of it. Wyverns in their ancient form are not actually anywhere near that big, being the size typically seen in games that feature knights that ride on dragons or wyverns. Their smaller size is due to their focus on speed. Dragons, on the other hand, are much larger in their ancient form. Even a young dragon is larger than a two story building, and they get bigger as they age. Some dragons are as large as multi story buildings or towers (the term used is ビル, biru, and while it technically just means building, Japanese typically use it to refer to buildings with many floors). As for wurms, they are larger than wyverns and smaller than dragons, but also vary the most in size from individual to individual out of the three races. (source: Personal communication with KC).
* Regarding men. With different mixes of Theriomorphosis Potion and use of magic, it is possible to control the temporary transformation to grow only specific monstrous parts you want, such as wings, horns or a tail. (source: Personal communication with KC).
* The magic pixies use to change size is something they naturally possess by birth. However, it is possible for this magic to be learned through training by other monsters as well. Accessories and clothes worn when changing size also change size, and revert when the user returns to normal size. However, things put on after the size change magic is used will not change, and will simply fall off or become undone when returning to normal size. (source: Personal communication with KC)
* Normally intense pleasure will cause the anthropomorphosis spell to be undone. However, there is a potion available and practical to find for monsters that enables anthropomorphosis to be sustained even during sex. (source: Personal communication with KC)
* Anthropomorphosis is easy for monsters to use because they are all already "half human." Actually changing into the form of another kind of monster, however, is much more difficult. Making a potion or spell to enable this would be difficult, and maintaining the change during sex would be even more so. Lilim are the exception though, magic designed for them to use on themselves could enable things such as "lamia transformation" more easily because lilim naturally have the mana of all monster varieties inside them. It can be said that they are suited to such magic. That said, such a transformation is not an inherent power of lilim, merely something some individuals learn.

However, because they are descended from minotaurs and dragons, they can use that ancient form if they transform (easy for a jabberwock, potentially possible for a holstaur).
3. Monsters that looked the same in the ancient era as they do now, such as lamia and succubi, of course have no ancient form to turn into. It may be possible for them to turn into a more monstrous form, but in that case it would just be transformation magic rather than taking on an ancient form.
* As for the ancient form, it's important to note this is not a "super mode." No monster is any stronger when transformed like this, so the uses for the form are more for utility such as providing greater reach, carrying more things, etc. In relation to this, it gives you a further sense of how powerful a monster like a dragon is in that she packs in a serious tail swipe in her human-sized form all the power that the tail of her ancient form has. (source: Personal communication with Kenkou Cross).
* Regarding what it looks like to transform into the ancient form, it varies with the individual. It typically is instant, accompanied by the body being surrounded by bright light, flames, or darkness like that of the dark matter. (source: Personal communication with KC).
* The size of the ancient dragon form varies with individual and race. Notably, the wyvern seen on the cover of the Dragonia book is meant to be a symbolic depiction of the "image" of Dragonia, representing various aspects of it. Wyverns in their ancient form are not actually anywhere near that big, being the size typically seen in games that feature knights that ride on dragons or wyverns. Their smaller size is due to their focus on speed. Dragons, on the other hand, are much larger in their ancient form. Even a young dragon is larger than a two story building, and they get bigger as they age. Some dragons are as large as multi story buildings or towers (the term used is ビル, biru, and while it technically just means building, Japanese typically use it to refer to buildings with many floors). As for wurms, they are larger than wyverns and smaller than dragons, but also vary the most in size from individual to individual out of the three races. (source: Personal communication with KC).
* Regarding men. With different mixes of Theriomorphosis Potion and use of magic, it is possible to control the temporary transformation to grow only specific monstrous parts you want, such as wings, horns or a tail. (source: Personal communication with KC).
* The magic pixies use to change size is something they naturally possess by birth. However, it is possible for this magic to be learned through training by other monsters as well. Accessories and clothes worn when changing size also change size, and revert when the user returns to normal size. However, things put on after the size change magic is used will not change, and will simply fall off or become undone when returning to normal size. (source: Personal communication with KC)
* Normally intense pleasure will cause the anthropomorphosis spell to be undone. However, there is a potion available and practical to find for monsters that enables anthropomorphosis to be sustained even during sex. (source: Personal communication with KC)
* Anthropomorphosis is easy for monsters to use because they are all already "half human." Actually changing into the form of another kind of monster, however, is much more difficult. Making a potion or spell to enable this would be difficult, and maintaining the change during sex would be even more so. Lilim are the exception though, magic designed for them to use on themselves could enable things such as "lamia transformation" more easily because lilim naturally have the mana of all monster varieties inside them. It can be said that they are suited to such magic. That said, such a transformation is not an inherent power of lilim, merely something some individuals learn.

* Once monsters become able to give birth to incubi there is a possibility of the incubus' mother's genes effecting what the incubus' child looks like. What is more likely though is that the disposition of the child may be effected to be different from the norm of her race. The examples given are an incubus with a devil mother could marry a weresheep and have a weresheep with ideology of the Radical Faction, or vice versa an incubus with a weresheep mother who marries a devil could have a devil daughter who is easygoing and likes to sleep a lot. (source: Kenkou’s Japanese Q and A).
* In addition to abilities mentioned in the settings books (incubi married to heat-loving monsters gaining resistance to heat, incubi married to aquatic monsters becoming able to breathe and swim quickly underwater, and so on), incubi married to monsters who prefer darkness, caves, etc. will gain excellent night vision. (source: Kenkou’s Japanese Q and A).
* Related to the above, incubi won't gain special abilities like lightning powers and extreme speed from a raiju simply by being married to her. However, he may gain visual acuity to a level that lets him track her high speed movements, as well as resistance to damage caused by lightning. (source: Patreon Q and A).
* Dragon husbands tend to gain stronger bodies, like heroes of myth who became immortal from bathing in dragon blood. They also gain resistance to the element of the breath weapon his wife uses. (source: Subscribestar reply)
* Aquatic incubi do not grow gills, their ability to breathe and speak underwater is entirely magical in nature. (source: Personal communication with Kenkou, plus descriptions of underwater breathing magic in Side Guide III).
* In the age of the former mamono lords there were male inma (who all became succubi when the current Mamono Lord came to power), but they were nothing like the incubi in the current age. The ability to transform a man into an incubus is something monsters gained in order to make living with human men as married couples easier after the current Mamono Lord came to power. (source: Kenkou’s Japanese Q and A).
* It is possible for an incubus to learn to handle the mental effects of doppelganger potions and function outside of sex even with multiple copies. A powerful yoko empress in the Mist Continent is said to be accompanied by many masked servants, all of them actually her husband using doppelganger potions to split himself into a lot of copies. (source: Kenkou tweet).
* For monsters that confine men for lengthy periods such as alraune and man eaters, their nectar, digestive fluids, etc. serve to keep the man's hair and body clean. It is believed waste is processed and dissolved to an extent both by magic and the monster's own fluids soaking into the man. (source: Personal communication with Kenkou Cross). Perentie note: I get the impression KC doesn't intend to go into more detail on how waste management works for the time being, beyond that it isn't an issue we have to worry about.
* Related to the above, unwanted hair growth is managed in a rather special way. Because the purpose of facial hair and other potentially unwanted hair is mainly for protection of the skin, and the man's body is kept so protected inside the body of monsters that trap men like this, over time his body will recognize there is no need for such protection and unwanted hair growth will cease. This is similar to why man eaters have no desire to wear clothing. (source: Personal communication with Kenkou Cross).
* While they do become able to think clearly in the midst of superhuman pleasure, this does not mean an incubus is actually resistant to pleasure, at least from his wife whose body and his have adapted to experience the greatest pleasures with each other. In fact, it can be said that just like his wife becomes "weaker" to pleasure from him, he becomes "weaker" to pleasure from her over time. Orgasms for both come more frequently and more easily, and he becomes more "vulnerable" to her body so he can offer up even more essence to her. For instance, it will become common for a man to orgasm from a deep kiss even if his genitals are not touched. (source: Personal communication with Kenkou Cross).
* While they may have certain aspects relating to the nature of their mother (such as the gentleness of a holstaur, or the fierceness of a hellhound), what will be especially prominent in natural born incubi is that they have a likelihood to have aspects of themselves that make them ideal husbands for the race their mother belongs to, and in turn to end up marrying the same or similar kind of monster. A holstaur's son may have eyes that are especially drawn to large breasts, and a hellhound's may exhibit behaviors that fierce monsters find appetizing. Rather than the mother, it seems the father's nature/interests is a big part of them inheriting these things, and over generations it may become even more pronounced.

All living things have a fixed "physical lifespan" in regards to their physical body specifically, as all physical life degrades over time. While mana growth can suppress deterioration and thus extend the lifespan, it doesn't stop it completely as it is not as if time is stopped.
A comparison can be made to machines with batteries. If you replace the batteries and keep up maintenance, then the machine will run much longer, but it will still eventually "die." The same is true for the most long-lived monster girls and incubi. They are in a sense durable "machines" with a very long service life.
Even the phoenix is not an exception to this. They are able to "live" forever because when their degraded body dies they have the power to construct a new body in its place and transfer their soul into it. The same thing happens to mortal life, just with a delay, namely their physical body dies, their soul goes to the afterlife and when reincarnating their soul is put into a new body.

Basically undead are able to twist the normal rules. "Living" things have their soul contained within a physical body, but the nature of the connection means the soul cannot continue to exist in the body once the body degrades. Undead twist this logic, as for them there is no severing of the body and soul, for them the physical body is not a "vital" thing but rather an incidental part of the soul (which is now the main body) worn by the soul like a garment. Further, their physical body has "stopped," so there is no degradation. Carrying out life activities is what degrades a living body, but for undead those life activities are caused by magic and the soul itself manifesting those changes in the physical body, creating a "pseudo life" that mimics life processes while not deteriorating. It can also be said that because the soul is now the "main body" their body is pulled along by the soul's own immortality. (source: Personal communication with Kenkou Cross).

* While a soul may be trapped or placed in a dormant state, it is likely impossible for any being to destroy it. For an example, there are means to damage a ghost's body, but what would be damaged is the body she constructed to interact with the physical world. Her actual soul would be unharmed, even if the constructed body was completely destroyed. She would simply become invisible to normal people and unable to interact with the physical world until she was able to recreate her "body." (source: Personal communication with Kenkou Cross).
* In short, when a man and monster marry their souls are always "stained/altered" so that their attraction to each other becomes eternal and they will eventually reunite when reincarnated and also regain at least some memories of their past lives with each other. "Soul stained" is a state of being. Their souls will also try to reincarnate at a time and location close to the other soul. (source: Personal communication with Kenkou Cross).
* The Ritual of Soul Marriage goes beyond even this though. Their souls are bound together in such a way that they are in a sense one soul, and one person can't be killed while the other still lives (this is what is meant by "won't be vulnerable to death" in World Guide 3's description, not that they can't die at all), and if one is an undead then their immortal undead nature will be shared with the spouse. If they are not undead then they will die at the end of their lifespan at precisely the same time as their spouse. Reincarnation is then effected so that they are certain to reincarnate at the same time and near to each other to make it easier to be reunited faster, such as in neighboring families or even as brother and sister (with the resulting forbidden romance, and this presumably refers to the future when monsters birth incubi, or rare situations where a monster's soul gets reincarnated in a human body, or other situations where a boy may end up with a monster girl sister). (source: Personal communication with Kenkou Cross).
* The "souls" of plants and animals are quite different from those of monsters or humans. So humans and monsters do not reincarnate as animals or plants. (source: Personal communication with Kenkou Cross).
* Normally a soul is reborn as the same gender they were in the previous life. Alps are an exception, as they reincarnate as women. (source: Personal communication with Kenkou Cross).
* Human souls can reincarnate as monsters, but as a rule the reverse does not happen. Monsters typically reincarnate as monsters. In the rare cases where their soul does reincarnate in a human body, they may find themselves filled with a particular lust for a certain man, and when the person monsterizes she may experience a strange sensation of "back to the real me."

* Generally all injuries and defects in the body are healed upon becoming a monster. However, depending on the experiences, memories, emotions, etc. of the woman, there are exceptions. Mersé, for instance, retained her scarred, blind right eye after becoming an echidna because it is a reminder of why she values being an ideal mother compared to her own mother, and she had already optimized her fighting style for her one-eye state. More generally, scars that relate to or remind a woman of the beginnings of her relationship with her husband may remain unchanged when monsterizing. Of course, if they ever change their mind there are usually still other ways to heal these things. (source: Ochiverde personal communication with Kenkou Cross).
* Parasitic monsters such as cursed swords, parasite slime and ropers, cannot parasitize monster girls. (source: Patreon reply).
* Regarding monsterization of cats and dogs, it requires strong individual affection and desire from the pet toward its master. Typically if the pet has more than one owner, their affection will be divided among different family members (including other pets) and monsterization will not occur, or it will be at least unlikely. On the other hand, when a man on his own in a mamono realm owns just one dog or cat, monsterization becomes likely. That said, ultimately it cannot be controlled by anyone, as it is the feelings and desires of the individual that cause the monsterization. (source: Personal communication with KC).

As a fantasy RPG setting, it is fair to say that melee weapons and magic in the MGE are far superior to real world firearms.

* One feature of the "Abyssal language" is that it is only pronounceable by married abyssal monsters, as speaking it requires overlapping her voice with that of her husband when their bodies are linked. This simultaneous speech is possible not through standard telepathy, as that would still have a time delay, but more through the couple being able to outright communicate to each other what the other is going to say or think before they say or think it, as if they were predicting each other's thoughts, allowing them speak as if they were one person. (source: Personal communication with KC).
* While she would find it embarrassing, an abyssal monster would not be averse to her husband always being in human form, including during sex. It is not at all inferior, and in the case of the atlach-nacha her toxin can be neutralized by the husband even in human form. In theory he could stay in human form all the time, as he can transform at will. However, as a married couple this would not be enough. It is the husband's responsibility to fulfill her desire to spend time in intercourse with his transformed state, and from his perspective to never do this would be like choosing to not breathe. He would eventually not be able to help himself. (source: Subscribestar reply)

There are male angel equivalents to valkyries, but they are not called valkyries. They have different roles, and rarely take on the role of being a guide for a hero. This may be due to how in the previous era almost all heroes were males (in the present era many are female), and so it has remained tradition that female angels guide heroes. When it comes to the angels of the main religion, i.e. that of the chief god, the ratio of male to female angels is roughly equal. However, there are no male cupids or houris.

* Unlike centaurs, tauric bug monsters like arachnes, giant ants, etc. only have one set of genitals. However, the egg will be laid from the rear end of the bug abdomen.

* Lower rank undead tend to be the only kind that can "evolve." However, it is not because they are low rank, but rather due to their history. In the previous era, zombies, ghosts and skeletons, etc. were just the dead being forced to move about. They were not actual races of monsters, or even lifeforms. While they did become lifeforms in the current era, it could be they are in a sense still "incomplete" and existing in a transitional state like a lesser succubus, becoming "complete" once they accumulate enough mana. In contrast, races like the vampire were already "complete" in the previous era as a race and may need no further changes. (source: Subscribestar reply)
* While undead can choose to return to the cycle of reincarnation, this will not happen often enough to control their population. Instead, the solution to a scenario where these immortal beings someday become too populous (to where they run out of room or vastly outnumber other kinds of monsters) is that in such a case their combined mana would be so massive as to be capable of forming a whole new world for them to move the excess population to. A result may eventually be an incredibly large world just for the undead, or multiple smaller worlds. (source: Personal communication with KC)

* Unlike centaurs, tauric bug monsters like arachnes, giant ants, etc. only have one set of genitals. However, the egg will be laid from the rear end of the bug abdomen. This "ovipositor" is not a sex organ, but enthusiastic couples may try using it as one with the man inserting his own member into it. (source: Personal communication with KC).
* Bug monsters when they lay eggs often lay multiple eggs. (source: Personal communication with KC).
* Tsukumogami monsters can be born anywhere in the world. However, they are more likely to be born in Zipangu, perhaps due to special differences in the air and mana there. (source: Kenkou's 2015 Ask.fm page).
* Undead being able to reproduce applies to those with entirely spiritual bodies as well, like phantoms and will-o-wisps, since they are a "race" rather than just a spirit. (source: Patreon PM from Kenkou).
* Lower rank undead tend to be the only kind that can "evolve." However, it is not because they are low rank, but rather due to their history. In the previous era, zombies, ghosts and skeletons, etc. were just the dead being forced to move about. They were not actual races of monsters, or even lifeforms. While they did become lifeforms in the current era, it could be they are in a sense still "incomplete" and existing in a transitional state like a lesser succubus, becoming "complete" once they accumulate enough mana. In contrast, races like the vampire were already "complete" in the previous era as a race and may need no further changes. (source: Subscribestar reply)
* While undead can choose to return to the cycle of reincarnation, this will not happen often enough to control their population. Instead, the solution to a scenario where these immortal beings someday become too populous (to where they run out of room or vastly outnumber other kinds of monsters) is that in such a case their combined mana would be so massive as to be capable of forming a whole new world for them to move the excess population to. A result may eventually be an incredibly large world just for the undead, or multiple smaller worlds. (source: Personal communication with KC)
* Beastmen types in general were among the monsters known to have in rare cases overcome their human-killing instincts and fallen in love with humans in the age of the former mamono lords. (source: Kenkou’s Japanese Q and A).
* When elves become able to birth incubi, the boy born will either have strong human characteristics, strong elf characteristics, or be an even mix of human/elf. (source: Subscribestar reply)
Slime mate selection
Spoiler
As old profiles, the slime's, red slime's, etc. can be a bit misleading. What they say is not wrong, but it is incomplete. Basically they only speak of one of the two means by which slimes mature and select husbands:
1. The mother extracts semen from the father, removes the personal information in it, and gives it to the daughter (this is similar to how essence supplements work).
2. The daughter extracts semen directly from the father.
In the former case, she'll become independent and leave to find a husband, in the latter her "father" is her husband. Incest is not taboo, but still considered rare among most monsters, but slimes are an exception to this for two special reasons (slimes and red slimes are specified, but this probably applies to bubble slimes and other lower rank slimes as well). These reasons are as follows:
1. Unlike most monsters, slimes are born with lust/appetite and bodies capable of indulging in it from the start. And the male they first encounter will of course be their "father."
2. Due to reproducing via fission, slimes may inherit some or even all of their "mother's" memories and feelings. In such cases their mentality is similar to that of a queen slime, more like clones than mother and daughter. They consider themselves to be the same person, and so the man they love will be the same. Whether this happens or not is dependent on the daughter's will, if she recognizes herself as the same as her mother then her mother will regard her the same way, so it is always a mutual feeling.

Akaname
The tongue of an akaname is very tough. There is a in-universe anecdote about one using her tongue to catch the sword of a villain who tried to attack her husband. (source: Kenkou's 2015 Ask.fm page).
Aka-Oni
Alice
Alices who adventure in Wonderland will “mature” in the sense of becoming able to fully remember their sexual experiences and become able to have children. It is said every alice will eventually go to Wonderland. (source: Wonderland online settings article).
Alp
While most alps are succubi, in some situations a incubus can become an alp version of other sorts of monsters (source: Kenkou Q and A tweet referring to alp slime carriers, and another to how a man can become the liliraune’s partner liliraune though it is not easy).
It’s not unheard of for an alp who has embraced her femininity to retain her “boyish” looks. Conversely sometimes a alp that has retained a male personality will still gain a voluptuous body. (source: World Guide 1 Sex Change article).
If a man has both the qualities to become an alp and a desire to remain with monsters as a man, then the stronger desire will win out (source: Kenkou’s Japanese Q and A).
Monsters generally will recognize ahead of time if a man has the qualities to become a alp (source: Kenkou’s Japanese Q and A).
Alraune
Members of the alraune family can pull up the roots of their flowers if they want/need to move about (source: KC’s notes on the barometz).
Due to the above, the husbands of alraune family monsters can even hold desk jobs, though their wives may distract them (source: PM from Exet_mos).
Sexual experiences cause a alraune to have her nectar "ripen" which enhances all its normal effects. This is why honey bees make sure to stimulate a unmarried alraune while collecting her nectar, and since the ripened nectar works even better at attracting men the alraune allows the fondling (source: World Guide 2 Alraune Nectar article).
By adjusting the size and shape of their flower and the angle of the petals, alraune monsters can sit down as if on a couch or lie down like on a bed, in short they are not stuck in a standing position. (source: Kenkou's 2015 Ask.fm page).
The humanoid portion of an alraune is similar to that of a sandworm in that it must remain connected to the flower, but the attachment point can change. Normally their feet are buried in the soft bottom of the flower, but they can raise one foot without issue. By changing the attachment point to another part of their body, they can even lift both feet to wrap them around their husband's waist. (source: Personal communication with Kenkou).
Amazoness
Most amazoness (but not all) have only one wing and cannot fly. They instead use their wing as a weapon to help them when hunting, as well as to boost their jumps and other athletic maneuvers (source: Kenkou’s Q and A thread).
There are many quite muscular amazoness (source: Kenkou’s Japanese Q and A).
While many monsters partially reverse typical gender roles, the amazoness are the only ones who completely do this as a society. Even monsters who typically take the aggressive lead in courtship or act as a man's protector will still see a man who does it as manly for doing so, so their views on men are not completely reversed. Amazoness though would see a tough and strong man as attractive for being tough and strong even though they are a man, similar to how real world men may admire strong women. (source: Subscribestar reply)
Angel
Ant Arachne
If an ant arachne's true identity is discovered it’s not really a big deal to the giant ants. However, they may put her to work as a sort of maid for them (source: Kenkou’s Japanese Q and A).
Anubis
Anubis tend to be close to average human men in height. (source: Subscribestar reply)
Ao-Oni
Apophis
While pharaohs bitten by an apophis will give up their throne in favor of spending even more time having sex, they aren’t stuck in their rooms and may even continue to assist in governing the realm (source: PM from Exet_mos and KC).
To stop a apophis from attacking a married pharaoh, the couple only need to show that they indulge in friendly sex together like a monster couple. The apophis loses her will/instinct to attack if she sees that the pharaoh is already a lecherous monster (source Patreon PM from KC, shown below).
アポピスの攻撃から妻のファラオを守りたい場合は、あなたとファラオが魔物の夫婦らしく二人で仲良くセックスに溺れている事を示すといいでしょう。
すっかり淫らな魔物になっているファラオを見てアポピスは攻撃の意思を無くします。
If you want to protect your wife Pharaoh from Apophis' attack, you can show that you and Pharaoh are indulging in friendly sex together like a monster couple. Apophis will lose her will to attack when she sees that Pharaoh has become a lecherous monster
The cobra-like head decoration the apophis wears is not physically fixed to her but is held on by magic so it is also not very heavy. (source: Machine translated Enty info article for the making of the apophis profile).
The red light from the jewels and decorations are from the apophis' enormous mana leaking out. (source: Machine translated Enty info article for the making of the apophis profile).
Human women turned into lamia by the venom of an apophis tend to end up having glamorous brown skin when monsterized. The apophis will also tend to give them lewd, dancer-like clothes to wear on their new body. (source: Personal communication with KC).
Arachne
Arch-imp
Atlach nacha
They are a race with a high proportion of loli individuals, but mature-looking ones also exist (source: Kenkou tweet shown below in answer to a question on if there were sexy mature atlach-nacha with large breasts).
おつありです。基本的にロリの比率が高い種族ですが、いないこともないってくらいには存在しますね。
Regarding the anatomy of the transformed husband, he places his mate not in a mouth but in a "reproductive pouch" (the tentacles in front of him are not his tongue). His real mouth is hidden behind the atlach-nacha's back, above the pouch. On the left and right side of her waist are the husband's red fangs, while the thin purple part surrounding the tentacles is his chin. (source: Enty info article for the making of the atlach-nacha profile).
As for the atlach nacha herself, on her own she looks much like a human girl, but with spider legs growing from her back and luminous orbs arranged like the extra eyes of a arachne. (source: Enty info article for the making of the atlach-nacha profile).
All arachne family monsters lay eggs (after a period of pregnancy), including the atlach-nacha. (source: Enty info article for the making of the atlach-nacha profile).
The spider form of an atlach-nacha's husband may be as big as a building, though this size is rare. (source: Personal communication with KC).
While all the luminous red objects on husband's body function as eyes, they do not all see the same way. The main eyes on his face and the pincer horns (jaws) see a clear image like human eyes. While not visible on the illustration, the eyes on the horns can also see the back of the wife, and their angle allows him to see the front of her too, which is a blindspot for the eyes on his head when they are having sex. However, the eyes on the rest of the spider's body and legs do not produce clear images, instead detecting light, body heat, mana, and the presence and general shape of objects. They are used mostly to detect prey in the web, or to allow the couple to survey the entire web when they are building it. (source: Subscribestar reply)
Automaton
Regarding their anatomy and how they feel, the exterior of their body is made of a hard, surprisingly light metal, while the torso is a mysterious, silicone-like material that is similar in softness to organic tissue. The metal armor may be kept on or removed during intercourse. (source: Enty info article for the making of the automaton profile).
The horn-like structures on their head have a radar function, and the device on their forehead has a camera feature that lets them see with more precision and detail than normal eyes (they often use it to look at their husband's privates). (source: Enty info article for the making of the automaton profile).
The gear-designed armor skirt is linked with the gears in their waist and they can change its angle. The weapon in each arm can be retracted or withdrawn at will, and their legs have powerful springs that let them leap great heights and deliver striking power that can crush stone. (source: Enty info article for the making of the automaton profile).
The characters on their lower abdomen contain information on their owner, i.e. their master/husband and are written in a mysterious, difficult to decipher text. These markings were originally not on that part of the body, moving their due to gremlins and the influence of monsterization. The markings blink gently when their master is near as a form of recognition, recognition which gets stronger the closer he is to them. Since the recognition is strongest during intercourse, the inscription has come to serve to give sexual desire to the automaton. Depending on the taste of the gremlin who remodeled them, the inscriptions may serve even further functions. (source: Enty info article for the making of the automaton profile).

Spoiler
Balrog
Their very long tail is normally held in loops in a clasp, and the whole tail can light on fire when unleashed. It is very powerful. (source: Personal communication with KC).
While the profile balrog is wearing gloves, these are special gloves that show off their nails. They are very proud of their nails. They wear no boots, having beast-like feet. Their feet and lower legs are furred, their upper legs are clothed and accessorized. (source: Personal communication with KC).
It's rare for a fight in a balrog city to require the intervention of a balrog. Mostly they're just little fights over trivial things, as the citizens get heated up in that way quite easily, but they don't usually escalate. (source: Personal communication with KC).
A balrog's husband is typically infused with about half of the balrog's own power. He is in turn often given the balrog's sword of fire, hence why the profile balrog does not have her famous sword. (source: Personal communication with KC).
As with many monsters, the power of a balrog is far stronger now than in the former era, but it is rare for one to get serious and show off this power. However, if there is a tremendous battle she may take the sword back and show off her true strength fighting with the sword of fire and her whip-like tail as in the past, and the sight of their power is astonishing. (source: Personal communication with KC).
Balrogs don't have any traditional outfit for their race, the profile one is wearing a outfit inspired by the Momonika Sabbath's styles but more adult and to her liking. However, many balrogs do have a preference for clothing that is black in color. There is an element of shadow to the balrog's design, hence their black wings and tail, in addition to black in their clothes. (source: Personal communication with KC).
The tongue of a balrog is similar to the magma of a lava golem. They give incredible licks and blowjobs. (source: Personal communication with KC).
Pyrows and balrogs have always been distinct races, the pyrows serving balrogs as small fiends of fire since ancient times. Thus, while a pyrow might become as powerful as a balrog, she won't actually become a balrog. Also, the special powers of the pyrow's flames originate from their masters, the balrogs. (source: Personal communication with KC).
As in the real world, most volcanoes are not erupting that often. Balrogs absorb the mana of a volcano constantly, keeping the volcanoe's "meter" close to 0. As such, even if a balrog takes a long trip, it's not a problem as the volcano's meter will not fill to the point of dangerous eruption before she gets back. There are also balrogs that do not control cities, but they still basically all live near volcanoes and absorb mana from volcanoes because for them this is a more comfortable way to live. (source: Subscribestar reply to DragonFall concerning if balrogs have to remain near volcanos to keep them dormant.)
Banshee
In the previous age banshee were originally a variety of elves, or something similar to them, cursed and sorrowful (as described in the profile) before Hel took them in as her servants. (source: Making of Banshee article on Patreon).
Their tears are not black, the dark lines on her face simply come from her crying often. (source: Making of Banshee article on Patreon).
Despite how their clothes pool around their feet (they are normal feet, just hidden under her clothes), banshee walk silently and without tripping. (source: Making of Banshee article on Patreon).
Baphomet
These are among the races known to have in rare cases overcome their human-killing instincts and fallen in love with humans in the age of the former mamono lords. (source: Kenkou’s Japanese Q and A).
Oppai-loli baphomets may exist, but they are incredibly rare and regarded as heresy by the Sabbath (source: Kenkou’s Japanese Q and A). Perentie note: This would eventually be explored in World Guide 3 and result in a oppai-loli Sabbath being officially accepted after much debate.
Basilisk
The gaps in some of her scales, both under her breasts and under her groin, constantly emit a glowing red color. This light is in fact the same toxic mana (maryoku) that fills their body (the light from the eyes of a unmasked basilisk is shown to be the same color in the extra art, likely confirming that their venom is their mana emitted from their eyes). (source: Machine translated Enty info article on the making of the basilisk profile).
Barometz
Members of the alraune family can pull up the roots of their flowers if they want/need to move about. In addition to walking on their roots, barometz may move by bouncing. (source: KC’s notes on the barometz).
Due to the above, the husbands of alraune family monsters can even hold desk jobs, though their wives may distract them (source: PM from Exet_mos).
Beelzebub
Bicorn
Unicorns and bicorns do not dislike each other. Bicorns tend to think about how great a unicorn they see would be as a bicorn, while a unicorn seeing a bicorn may feel curious about becoming a bicorn. However, bicorns will not change unicorns indiscriminately. Just as when adding harem members, they consider the relationship status of the unicorn, who she is in love with, etc. and would not change a happily married unicorn (source: Patreon Q and A).
Black Harpy
Harpies all have clawed hands that are normally hidden within the feathers of their wings. (source: Ghandharva profile art, also KC&Will Book Launch Q&A).
Boggleboe
Boggleboe only form from the spirits of young girls, and their appearance is based on how they looked in life. Thus, the natural body of a boggleboe can't look like an adult. However, some girls do mature in appearance earlier than others, and in such a case a boggleboe with a more mature body may be born. (source: Personal communication with KC)
The stuffed animal that the soul of the boggleboe merges with is based on her own desires, so typically it will be of a cute or common stuffed animal as it is what she would be familiar with and like. Stuffed animal versions of snakes and spiders are rare, and so are boggleboe versions of them. (source: Personal communication with KC)
They are mysterious undead, as their humanoid bodies form from "nothing" instead of a corpse, and these bodies are more similar to goblins in structure rather than a witch or other majin. The reason for all this is secret for now. (source: Personal communication with KC)
The "blood" on the costume is her own mana and pheromones seeping out. (source: Personal communication with KC)
If she is separated from her costume she can still move it to an extent with her will (an example being using it to hold her prey in a headlock), but she can't control it as if it were a living thing. However, she can summon it to her side and put it on in an instant. (source: Personal communication with KC)
Bubble Slime
Bunyip
The feathers are attached to her mask, they are not part of the bunyip, and the mask is the only thing she is wearing. The fur covering her nipples is also part of the mask, attached to the decorations on said mask (these decorations can mysteriously cover her nipples when she wears the mask). These masks are a long-running tradition among bunyip, as they believe wearing them will grant them courage when coming in contact with men. (source: Enty info article for the making of the bunyip profile).
They are known for having pretty, almost child-like voices, as if they were frail and slender girls instead of the large, intimidating women they are. This can make them sound rather ominous, as even a timid "Uuu..." will reverberate while wearing their mask. (source: Enty info article for the making of the bunyip profile).
The bunyip tongue has a particularly high temperature compared to other types of lamias. When kissing, it seems especially soft and comfortable, which is why, as they say, with a deep kiss, they are able to completely disable the brain of the husband
(source: quote of KC tweet).

Thus, while a pyrow might become as powerful as a balrog, she won't actually become a balrog. Also, the special powers of the pyrow's flames originate from their masters, the balrogs. (source: Personal communication with KC).
As in the real world, most volcanoes are not erupting that often. Balrogs absorb the mana of a volcano constantly, keeping the volcanoe's "meter" close to 0. As such, even if a balrog takes a long trip, it's not a problem as the volcano's meter will not fill to the point of dangerous eruption before she gets back. There are also balrogs that do not control cities, but they still basically all live near volcanoes and absorb mana from volcanoes because for them this is a more comfortable way to live. (source: Subscribestar reply to DragonFall concerning if balrogs have to remain near volcanos to keep them dormant.)
Banshee
In the previous age banshee were originally a variety of elves, or something similar to them, cursed and sorrowful (as described in the profile) before Hel took them in as her servants. (source: Making of Banshee article on Patreon).
Their tears are not black, the dark lines on her face simply come from her crying often. (source: Making of Banshee article on Patreon).
Despite how their clothes pool around their feet (they are normal feet, just hidden under her clothes), banshee walk silently and without tripping. (source: Making of Banshee article on Patreon).
Baphomet
These are among the races known to have in rare cases overcome their human-killing instincts and fallen in love with humans in the age of the former mamono lords. (source: Kenkou’s Japanese Q and A).
Oppai-loli baphomets may exist, but they are incredibly rare and regarded as heresy by the Sabbath (source: Kenkou’s Japanese Q and A). Perentie note: This would eventually be explored in World Guide 3 and result in a oppai-loli Sabbath being officially accepted after much debate.
Basilisk
The gaps in some of her scales, both under her breasts and under her groin, constantly emit a glowing red color. This light is in fact the same toxic mana (maryoku) that fills their body (the light from the eyes of a unmasked basilisk is shown to be the same color in the extra art, likely confirming that their venom is their mana emitted from their eyes). (source: Machine translated Enty info article on the making of the basilisk profile).
Barometz
Members of the alraune family can pull up the roots of their flowers if they want/need to move about. In addition to walking on their roots, barometz may move by bouncing. (source: KC’s notes on the barometz).
Due to the above, the husbands of alraune family monsters can even hold desk jobs, though their wives may distract them (source: PM from Exet_mos).
Beelzebub
Bicorn
Unicorns and bicorns do not dislike each other. Bicorns tend to think about how great a unicorn they see would be as a bicorn, while a unicorn seeing a bicorn may feel curious about becoming a bicorn. However, bicorns will not change unicorns indiscriminately. Just as when adding harem members, they consider the relationship status of the unicorn, who she is in love with, etc. and would not change a happily married unicorn (source: Patreon Q and A).
Black Harpy
Harpies all have clawed hands that are normally hidden within the feathers of their wings. (source: Ghandharva profile art, also KC&Will Book Launch Q&A).
Boggleboe
Boggleboe only form from the spirits of young girls, and their appearance is based on how they looked in life. Thus, the natural body of a boggleboe can't look like an adult. However, some girls do mature in appearance earlier than others, and in such a case a boggleboe with a more mature body may be born. (source: Personal communication with KC)
The stuffed animal that the soul of the boggleboe merges with is based on her own desires, so typically it will be of a cute or common stuffed animal as it is what she would be familiar with and like. Stuffed animal versions of snakes and spiders are rare, and so are boggleboe versions of them. (source: Personal communication with KC)
They are mysterious undead, as their humanoid bodies form from "nothing" instead of a corpse, and these bodies are more similar to goblins in structure rather than a witch or other majin. The reason for all this is secret for now. (source: Personal communication with KC)
The "blood" on the costume is her own mana and pheromones seeping out. (source: Personal communication with KC)
If she is separated from her costume she can still move it to an extent with her will (an example being using it to hold her prey in a headlock), but she can't control it as if it were a living thing. However, she can summon it to her side and put it on in an instant. (source: Personal communication with KC)
Bubble Slime
Bunyip
The feathers are attached to her mask, they are not part of the bunyip, and the mask is the only thing she is wearing. The fur covering her nipples is also part of the mask, attached to the decorations on said mask (these decorations can mysteriously cover her nipples when she wears the mask). These masks are a long-running tradition among bunyip, as they believe wearing them will grant them courage when coming in contact with men. (source: Enty info article for the making of the bunyip profile).
They are known for having pretty, almost child-like voices, as if they were frail and slender girls instead of the large, intimidating women they are. This can make them sound rather ominous, as even a timid "Uuu..." will reverberate while wearing their mask. (source: Enty info article for the making of the bunyip profile).
The bunyip tongue has a particularly high temperature compared to other types of lamias. When kissing, it seems especially soft and comfortable, which is why, as they say, with a deep kiss, they are able to completely disable the brain of the husband
(source: quote of KC tweet). Spoiler
Candlegeist
Their wax does not feel hot nor will it leave burn marks, though it may leave traces of their mana. The wax that drips off of them naturally forms into heart shapes. After receiving a lot of service from one in the cowgirl position, a man may be covered in heart-shaped bits of wax along his chest and lower abdomen. (source: Personal communication with KC).
Their body is more solid than a slime, but slightly softer and more elastic than a human. The parts that melt are similar to the consistency of a dorome. (source: Personal communication with KC).
Their wax body can freely detach from their candlestick "legs" in an act comparable to taking off shoes. When they do, they float in the air with their thighs being all that consists of their legs. But then melted wax flows down, and forms into wax lower legs and bare feet. (source: Personal communication with KC).
Their metal candlestick legs are mostly rigid, but can bend at the knee like melted metal. (source: Personal communication with KC).
They can generate a wick and light a flame from any part of their body. (source: Personal communication with KC).
The length of her cloak barely covers her butt, so the strategic placement of candles on the back of her feet serve to illuminate her rear to draw attention to it as she moves about.(source: Personal communication with KC).
The eyes seen on her cloak embody the thoughts of the countless candles that form a candlegeist. When she gets serious and her emotions run high, such as if someone appears who wishes to harm her husband (all the candles get angry and prepare to fight), or her husband gives her a gift of gratitude (the candles become unbearably happy and she is so full of love that she is on the verge of reversing her service), many black eyes will appear on the back of her cloak. (source: Personal communication with KC).
Cancer
A cancer's shell can open wide enough for the humanoid part to lie on her back, essentially turning her crab portion into a bed for herself and her husband. (source: Kenkou's 2015 Ask.fm page).
The hands and arms of a cancer look normal, they are hidden in the illustration to draw more attention to her crab lower body. (source: Machine translated Enty info article on the making of the cancer profile).
The crab eyes are not exactly real eyes, but they do function, giving her a wide field of vision and letting her look at every inch of her husband while embracing him. (source: Machine translated Enty info article on the making of the cancer profile).
Centaur
The second vagina centaur family monsters possess developed due to their desire to face their lovers while having sex. (source: Kenkou's 2015 Ask.fm page).
Centaur races are a big deal in tourist areas. Gambling over them is seen as a good way to attract men. (source: Patreon Q and A).
Centaurs do not have a second set of breasts on their horse body, and when it comes to pregnancy they carry the child in the human abdomen. (source: Personal communication with KC).
Charybdis
Cheshire Cat
Chimaera
The goat and dragon heads on her arms are a part of her body. (source: Personal communication with Kenkou).
The blue and red lines extending from a chimaera's shoulders are lines of magical power. They do not hinder her movement, and they simply extend if she raises her arms. (source: Patreon PM from Kenkou).
In addition to regular reproduction, chimaeras can be created through the use of extremely advanced magic by a skilled sorcerer or alchemist. The process involves mixing into a Mana Cage pure mana from the monsters that the chimaera is intended to be a combination of, then performing various rituals to bring the chimaera into being. (source: Patreon Q and A).
A "dark beast" is defined as a monster that has elements of real animals. Most chimaeras are combinations of reptiles and mammals, followed by birds, fish, insects, etc. in increasing rarity. Using non-dark beasts (such as slimes or fiends) is possible, but very difficult and so chimaeras that incorporate such combinations are rare. Even rarer and more difficult are ones that are made from living masses of mana such as dark matter and other elementals. (source: Subscribestar reply)
Normal dragons are typically used for creating chimaeras, but malef dragon is also an option (the question was specifically if a malef dragon could work, so other dragons were not mentioned). (source: Subscribestar reply)

Creeping Coin
Creeping coins usually don't appear in front of human women seeking riches, and their power to turn greed into sexual desire is used according to the creeping coin's own will and not usually directed as women. However, in the rare case that there is an exception, the woman will be turned into a creeping coin herself and her greed will turn to finding a husband as much as toward satisfying her financial desires (source: Patreon reply).

A cupid has four wings and they are shaped like hagoromo, i.e. something variously translated as heavenly raiment, a robe of feathers, a feather mantle, heavenly kimono of tennin, etc. (source: Patreon PM from Kenkou).
Cursed Sword
Cursed swords can get pregnant, and they give birth to fairly normal-looking children. However, as the child grows she will develop the sword and chitin armor over time as it sort of grows out of her body. This is at least in part due to how uncomfortable giving birth to a armored baby would be. (source: Response to questions on the "Making of" cursed sword article on Enty, summary translation posted on 4chan, also KC&Will_Book_Launch_Q&A).
The armor growth/corruption on a woman's body from a cursed sword begins with the hand and extends from there over time (source: Response to questions on the "Making of" cursed sword article on Enty, summary translation posted on 4chan, no further details known).
Like with the mershark's bite, the essence that leaks out from wounds by a cursed sword is colored crimson, making for a violent look even though no one is actually hurt. (source: Enty info article for the making of the cursed sword profile).

Dark elves can use magic to temporarily turn their skin white/light and may do so if their husband likes it. However they will want him to love their dark skin as well. (source: Kenkou’s Japanese Q and A).

The, crystaline core of the dark mage's cane is all a single glowing magic gem. Her disconnected garter belt is held together by magic. (source: Enty info article for the making of the dark mage profile).
The monsters shown in profile illustrations are often married individuals, hence why the Wandering Scholar can interview them without worry. The dark mage shows this by having a wedding ring on her left ring finger. (source: Enty info article for the making of the dark mage profile).
Dark mages look so human because they embraced monster girl-like behavior as humans, the defining point being that the monsterization originated from within them, being close to monsters before they are even exposed to mamono mana. (source: Comments related to Enty info article for the making of the dark mage profile).
While it isn't a actual feud, the fact that dark mages tend to be more reckless with their magic, causing various big incidents, and get confused with Sabbath's witches by regular people, etc. means that many Sabbath witches do get upset at the damage that is dealt to their reputation. (source: Comments related to Enty info article for the making of the dark mage profile).
Dark Matter
A dark matter who has fused with a woman loses the ability to do so again. If she were to go after another human woman that woman would become a succubus instead.
If an orgy of powerful monsters and their husbands takes place in a confined space sealed off so their mana cannot escape, and the orgy goes on for long enough, then a dark matter will be born from the accumulating energy. However it would be rare/difficult to keep enough couples there for long enough to accomplish such a feat (many would halfway through want to leave to have sex elsewhere or take a break to look forward to the next time they have sex).

In the era of the former mamono lords, devil bugs were infamous for their swarms invading towns and devouring them from the inside out regardless of precautions the population took. (source: Enty info article for the making of the devil bug profile).
Despite their love of filthy environments, devil bugs themselves have relatively clean bodies thanks to the protective effects of mamono mana. (source: Enty info article for the making of the devil bug profile).
The "spikes" on her arms and legs are actually more like hair and rather soft. The structure on her back, only partially visible, is designed to look like insect legs cradling her body (two of said legs cover her breasts). (source: Enty info article for the making of the devil bug profile).
Dhampir
Like other undead, vampires were unable to reproduce in the era of the former mamono lord, so dhampirs did not exist. (source: Patreon Q and A).
Regarding dhampir anatomy, they typically have human-like ears. The dhampri Alameria from Side Guide II gained pointed ears due to Druella's influence and Lescatie's dense mana causing her body to become closer to a vampire, i.e. making her monstrous aspects stronger. In either case, the dhampir's cape is just part of her costume, not part of her body like the vampire. (source: Personal communication with KC).
Doppelganger
If a man falls in love with a woman he sees in a painting or other illustration, a doppelganger can still take on her form. (source: Kenkou's 2015 Ask.fm page).
Doppelgangers reproduce conventionally, and the children have an appearance that combines aspects of their father and their mother's original body. Despite not being born from unrequited love, they can still transform, and will take on the form of the ideal woman of the man she chooses to target. (source: Personal communication with KC)
Doppelgangers cannot transform into whatever they want, their change being dependent on what the man they target wants most. They can change into the forms of other monster girls, but there are limits to the abilities they can copy. A doppelganger for instance, could change into a normal cat if she took the form of a nekomata, however, if she took the form of a lilim she would not be able to use their ability to monsterize women into practically any kind of monster (as they lack the special mana combination the lilim have). As a rule, they can imitate abilities that can also be produced by general-purpose magic (such as transformations), but cannot use magic specific to particular races of monster or abilities that result from special factors. (source: Personal communication with KC)

Compared to gnomes, they are not very good at giving their husband earth magic, shaping earth with precision, or upgrading plant monsters (however, this implies they are still able to do this to a degree). (source: Enty info article for the making of the dorome profile).
The darker mud of her torso is hardened compared to the surrounding mud, giving her some firmness there. The crystal on her chest is not a core, but crystalized mamono mana that forms something like a low purity earth magic stone.

The jewel can be used in the creation of various magical tools and armors. (source: Patreon PM from Kenkou).
Dragons have a "reverse scale" much as ryu do. However, it is smaller and harder to find compared to a ryu, and their reaction to it being touched is not as extreme as that of a ryu. Given the dragons are more likely to initiate mounting their men than the other way around, their mates do not often come into contact with their reverse scale. (source: Kenkou's 2015 Ask.fm page).
Dragonewt
Many dragonewts cannot transform. However, some powerful ones can become giant dragons, and these individuals are greatly respected by other dragonewts and often hold high positions. (source: Personal communication with Kenkou).
When a woman is transformed by a malef dragon or a dragonewt, if she has the proper qualities she will become a malef dragon instead of a dragonewt. A dragonewt who has accumulated power over time may also one day transform into a malef dragon. However, unlike with a lesser succubus, this is not something that is expected to happen and often it never will. (source: Personal communication with Kenkou).

Many dragonewts cannot transform. However, some powerful ones can become giant dragons, and these individuals are greatly respected by other dragonewts and often hold high positions. (source: Personal communication with Kenkou).
When a woman is transformed by a malef dragon or a dragonewt, if she has the proper qualities she will become a malef dragon instead of a dragonewt. A dragonewt who has accumulated power over time may also one day transform into a malef dragon. However, unlike with a lesser succubus, this is not something that is expected to happen and often it never will. (source: Personal communication with Kenkou).
Dragon Zombie
While their thoughts have become simple, dragon zombies are just as intelligent and knowledgeable as they were in life, and will use this to help them catch men. (source: Machine translated Enty info article on the making of the dragon zombie profile).
The jewel on the chest, possessed by other dragons, is notable here for glowing dimly like a soul. (source: Machine translated Enty info article on the making of the dragon zombie profile).

Dwarf
Dwarves and elves are considered to count as “human race” in KC’s world, and thus when it becomes possible to birth males they will be able to give birth to incubus dwarves and incubus elves respectively. (source: Kenkou Q and A thread).

Echidna
It is said there was a Mamono Lord named Tiamat, the “mother of monsters” who possessed the power to birth many kinds of monsters. This trait was likely passed down to a specific species that descended from her. (source: Patreon Q and A).

Even after becoming monsters elves rarely visit human towns (source: Kenkou Q and A thread)

Fairy
Fairy Kingdoms exist in various places throughout the world, but are in another dimension and thus inaccessible by normal means (source: supplemental notes on the titania profile).
When monsters of this tiny size become able to give birth to incubi, the baby will be correspondingly tiny and grow to normal human size in the process of growing up. (source: Kenkou's 2015 Ask.fm page).
Familiar
Creating a familiar is very advanced magic, but baphomets have simplified the formula over the years to make it easier. However, it still takes a large amount of mana so a baphomet cannot make multiple familiars at once. (source: Patreon Q and A)
Flow Kelp
Flow kelps lack lower arms and hands but can manipulate their leaves with finger-like dexterity. (source: Personal communication with Kenkou).
When KC made her he didn't have a role among the sea monsters for her in mind, but with the sea bishop being a cleric and the unreleased knight-type shrimp girl, he thinks the flow kelp would be good in a mage role. (source: Machine translated Enty info article on the making of the flow kelp profile).
The yellow part above her breasts is equivalent to the stem of a kelp. It glows with mana. Flow kelps are technically naked, since all their kelp is part of them. (source: Machine translated Enty info article on the making of the flow kelp profile).

Gandharva
Harpies all have clawed hands that are normally hidden within the feathers of their wings. (source: Ghandharva profile art, also KC&Will Book Launch Q&A).
Gargoyle
For a gargoyle, petrifying at the moment of ejaculation is incredibly blissful. However, if the man is not yet an incubus he may feel like he is going insane (though he will not actually go insane) from the overwhelming pleasure that keeps hitting him until the sun goes down. However, the experience is not like "being aware but unable to move," rather it could be compared to experiencing a dream, a dream wherein he is having sex with the gargoyle and unable to stop endlessly releasing inside her. (source: Personal communication with KC).
Gazer
The black substance covering the gazer's body is called "mysterious gazer gel" and she makes it by semi-solidifying her mana. It protects the gazer's body, is soft to the touch, removable, and can change shape by the will of the gazer. (source: Kenkou's 2015 Ask.fm page).
Genie
In theory a genie could grant a wish that allows her husband to gain power comparable to the Mamono Lord. However, it would require an extremely large amount of time (so presumably there isn't really a point to it). (source: Patreon Q and A)
Newborn genies are born with a tiny lamp of their own (presumably it is a mana construct) and it grows with the genie.
While the sun god did use their own mana to create genies, they also used the mana of monsters. Thus genies easily became monsters despite not being them originally. (source: Making of Genie article on Patreon).
The ornaments of the magic lamp and the genie's necklace have the same design, showing they are two parts of the same genie. (source: Making of Genie article on Patreon).
The magical smoke in her pants produces the patterns seen by flowing continually. Her smoke is part of her body, shown by being the same color as her hair, and made of her mana. (source: Making of Genie article on Patreon).
In theory the genies in the MGE have the "only three wishes" rule as one of the controls on their power, but this rule became very flexible when they became monster girls. When they like a man they will give him extra wishes, and also give extra wishes if the first three end up not being enough to make him her husband. (source: Making of Genie article on Patreon).

The white protuberances on the arms and chest of a ghoul are bones that have transformed into shells. She can make them appear or disappear at will using magic (source: Kenkou’s Japanese Q and A).
Giant Ant

Glacies
Hot springs won't harm them, but they will make their minds feel soggy and their bodies hot. Sex will inevitably result if someone they want is there (source: Kenkou’s Japanese Q and A).
The identifying information within essence is most concentrated in semen and saliva. It dissipates the further it spreads out, mixing with mana already in the air until the personal information is completely lost. So a glacies feeding on a man near her via the cold air method will get some of the information, whereas an ice queen feeding from great distances will get none at all. (source: Personal communication with KC)
Gnome

Greenworm
Their body is noted to be elastic and soft, reminiscent of a cushion or body pillow with a soft filling. The eye markings were, in the previous age, intimidating googly eyes to frighten humans, but now have a sleepy, cute look as a reflection of the greenworm's inner self. (source: Machine translated Enty info article for the making of the greenworm profile).
Excess skin behind the head forms something like a hood, and they in fact can pull this up and wear it on their head. (source: Machine translated Enty info article for the making of the greenworm profile).
The legs on their upper body can be moved freely, but are seldom used compared to their walking legs and arms. They may grab their partner during intercourse, but these legs are so short that it's often a wasted effort. (source: Machine translated Enty info article for the making of the greenworm profile).
The decoration on their neck is made of vegetables they gather as "emergency food." However, they have little self control over eating this stash, and so the look of the food and the vegetables stored frequently changes. (source: Machine translated Enty info article for the making of the greenworm profile).
If her husband wants the greenworm to remain as she is, then her body will recognize her current state as ideal for reproduction and she will not metamorphose. (source: Machine translated Enty info article for the making of the greenworm profile).
Monsters in a harem with a phoenix will be resurrected along with her and their husband. For greenworms this allows for a number of mechanics to come into play. For starters, if they were a papillon at death then they will revert to being a greenworm again. However, the abundance of mana that fills them in association with resurrecting means that if they want to they can immediately encase themselves, the phoenix and their husband in a chrysalis to become a papillon. Technically they have so much energy in this state that they don't even need to go into the chrysalis and can simply transform directly into a papillon, but they'll still do it because they want to enjoy the frenzied sex inside the chrysalis. As for becoming a papillon, they can return to their fully adult appearance immediately, or choose to be a "loli" papillon for a while. Their ability to store so much mana, and to alter their body with their will in various ways due to their unique biology is what grants them so much flexibility in how they develop when resurrected like this. (source: Personal communication with KC)
Gremlin
Gremlins originally had wings and a tail like other imps, but these degenerated over time as they got in the way when working on machines. (source: Enty info article for the making of the gremlin profile).
The machine they are pictured with is of the same technology as the automaton, but brand new, and it is worn like a jet pack. It uses mamono mana as propulsion. The large hands are identical in structure to the automaton's but with black cushions to act as a seat for the gremlin. The smaller arms and their tools are used for precision work, such as lewd remodeling of golems and automatons, as well as monsterizing women (the nozzles inject mamono mana). (source: Enty info article for the making of the gremlin profile).
Griffon
The griffon's poncho is supposed to be draped over her wings, her wings being over it is a drawing error. (source: Machine translated Enty info article for the making of the griffon profile).
The griffon's voluminous wings, lower body, and breasts, are meant to convey the size of her body (implying she is a relatively large monster girl). (source: Machine translated Enty info article for the making of the griffon profile).
As hinted at with the Griffon Feather Pen item, griffon feathers have the inherent power to levitate and be manipulated at a distance by their user. A griffon can detach/shoot her feathers and use them for various purposes, such as secretly launching or floating them into the pocket or luggage of a man she has targeted as her prey, marking him as hers. (source: Personal communication with Kenkou Cross).
Griffons prefer to sleep in straw (or similar material) beds that are shaped like bird nests. These are the griffon nests that people seek to steal griffon feathers from. (source: Personal communication with Kenkou Cross).
While their ancient form may be practical for carrying him on their back, both dragons and griffons in their humanoid forms like to carry their husbands around in their arms like treasures or princesses.

Harpy
Even in the age of the former mamono lords, monsters of the lamia and harpie families (among others) were still dependent on human men for reproduction. Normally there was no love involved, and once young were born the man would be eaten. However, in rare cases the monster would awaken to feelings of love and affection, overcoming her killing instincts and living with the man as something like a married couple.

Hellhound
The fluffy fur on the hellhound's chest produces a fragrant scent that both ignites lust and weakens a man's body when inhaled. It induces a feeling of security and a desire to entrust himself to the hellhound. The strength of the scent is proportional to how excited the hellhound is, and how much she has exerted herself, so if a man runs from her it's especially potent (source: Kenkou tweet shown below).

They use them to hold a mixture of herbs and such to make a secret medicine known only to orcs (who in turn use their keen sense of smell to gather the ingredients). This "secret medicine" is applied by placing the mushroom cap on their husband's member like a condom. It soaks into him during sex, causing the member to swell until the cap breaks. The main effect noted for the medicine is that it makes the man as sensitive as a virgin. (source: Machine translated Enty info article for the making of the high orc profile).

Holstaur
The breast size of a holstaur does vary, but KC places a upper limit of them not being bigger than the holstaur’s body (source: Kenkou Q and A thread) Perentie note: The question was asked to Kenkou due to a faulty translation of the holstaur book profile that implied a holstaur can change the size of her breasts (a more proper one simply was referring to how well she can move and shape them for paizuri), so it seems likely Kenkou thought the question was about those who are into extreme breast sizes and shouldn't be taken as implying holstaurs KC depicts would have breasts anywhere near the size of their own bodies. But that is just my interpretation.
There are individual differences, but the breasts of holstaurs normally start to noticeably grow during kindergarten age. By elementary school age they are already oppai-lolis. (source: Kenkou’s Japanese Q and A).
In winter, the Holstaur's chest continues to retain heat: you will warm up if you bury your face in it. (source: quote of KC tweet).
Honey Bee
Sexual experiences cause a alraune to have her nectar "ripen" which enhances all its normal effects. This is why honey bees make sure to stimulate a unmarried alraune while collecting her nectar (source: World Guide 2 Alraune Nectar article).

The ice queen's clothes are made of ice and she can change how the clothes look at will. They are pretty indifferent about it on their own, but may change the design at their husband's request or to surprise him. When her dress touches the ground it spreads out like it is crystalizing. The clothes also react to her emotions, namely if she is seriously angry (such as if her husband even looked hurt), the hem of the dress would spread out ice crystals across the surrounding ground and engulf the whole area in biting cold.

The tentacles of a jabberwock can be controlled by them like a second set of arms. Jabberwocks themselves don't know why in particular they have them, and mostly use them to lick and suck on a male's body. (source: Kenkou’s Japanese Q and A).
The heart markings on her body are to show off how often she has had sex with her husband. It isn't one heart per intercourse, but more like one for every hundred rounds of sex. (source: Enty info article for the making of the jabberwock profile).
Jinko
Despite their length, a jinko can retract her claws. (source: Kenkou’s Japanese Q and A).
Jinko tend to be taller than average human men. (source: Subscribestar reply)
Jinn of the Jar
Mimics and jinns of the jar do not have a single dedicated chest/jar of their own. Indeed they are born without any. Rather, they make ordinary chests/jars into parts of themselves. They may have favorites among this collection, and also change their chest/jar every day like changing clothes. A husband giving them a new chest/jar is often considered a good gift. (source: Patreon Q and A)
Jorou-gumo
Just as with other monsters, they do not like to see their husband hurt or suffering. Their sadism is limited to a instinctual preference for the sight of a man who is at the mercy of their hands, the look on his face when he can no longer endure the pleasure and cums, etc. (source: Patreon Q and A).
Regardless of how the man behaves, a jorou-gumo's "night face" will not go away completely, nor will her time spent in it extend beyond the normal length. (source: Patreon Q and A).

Kamaitachi
The thigh length tabi socks they appear to be wearing are in fact just fur that grows to look like tabi (source: Kenkou tweet)
The trio can be any combination of body types, be they three mature big sister types, three lolis, or anything inbetween, so long as they have all three types of scythes between them (source: Enty info article for the making of the kamaitachi profile).
While any given trio doesn't have to be related, the three in the profile art are, hence having similar coloring and motifs. It is also clarified that the one with the sharpest sickles in the image is the one with the longest sickles. (source: Enty info article for the making of the kamaitachi profile).
Kappa
What looks like clothing is actually the kappa's own scales growing out to appear like a swimsuit (this explains how she can have a shell growing over part of it) (source: Kappa book profile).
Karakasa-Obake
The tongue of the umbrella grows out from the inside of the top of the umbrella. As part of her body, it has the capacity for sensations. The umbrella has a dull sense of pain, but feels pleasure when stroked. (source: Kenkou's 2015 Ask.fm page).
The eye on the umbrella can see things, and is useful for when the karakasa is closed up in the umbrella with her husband. (source: Kenkou's 2015 Ask.fm page).
While their legs are often bound together with cloth like in the illustration, they can float and bounce with magic to move freely (and this applies when closed up in the umbrella too). They have great balance, but still fall over sometimes. And of course, since the cloth is made of mana (as evidenced by its transparency), they can make it vanish at will. (source: Kenkou's 2015 Ask.fm page).
The umbrella part cannot be truly detached from the rest of the karakasa. However, the link is magical rather than physical, so (for instance) if the karakasa lies down then the umbrella will float over her like a canopy. In other words it is not stuck in place on her head. (source: Kenkou's 2015 Ask.fm page).
The umbrella's tongue can shift in size and length at will. (source: Kenkou's 2015 Ask.fm page).

Kelpie
Kelpie only inhabit lakes due to them preferring calm waters over flowing currents. (source: Personal communication with Kenkou Cross).
The crown of water worn by the profile kelpie is not a characteristic of the species but rather this individual. She creates and wears it because she is regarded as lord of the lake by the humans of the area. (source: Personal communication with Kenkou Cross).
Kelpie hair is transparent due to water elements within it, but is not itself made out of water. Such water elements run through their whole body and thus their bodies look moist and shiny even when not wet. (source: Personal communication with Kenkou Cross).
For some reason, many kelpies enjoy singing, and can present themselves rather like divas. Due to this and the graceful way they run through water, they are sometimes used as motif in stage performances and they themselves may be quite good at such dancing and performing as well. (source: Personal communication with Kenkou Cross).
Humans continue to fall for the ruse of kelpies for a few reasons. The first is that the number of people who know the information from the monster girl encyclopedia is still limited, since it and books like it are prohibited by the Order. Even those who know a bit about them though still can't resist them, that's part of the charm of monster girls. With the kelpie in particular, humans find it difficult to connect in their minds the idea of a "a terrifying monster that drags you into the water" with the beautiful, ephemeral girl they see before them. Also, since local people often revere kelpies as lake spirits or guardians, such people won't warn men targeted by kelpies either. The husbands also don't warn people, and indeed often can't shake the image of a "pure girl" they have in their heads regarding her even after being one-sidedly ravished by their kelpie wife. There are no photographs or videos for people to observe, and people who know of kelpies usually have only read about them or seen artistic renditions. (source: Personal communication with Kenkou Cross).
Husbands of kelpies gradually become water breathing incubi, either through a ritual like what the sea bishop does, or simply from gradual exposure to her mana. That said, kelpies and their husbands typically choose to live on the lake shore or somewhere nearby rather than in the lake itself. (source: Personal communication with Kenkou Cross).
In dark mamono realms there are ordinary blue kelpie in white clothing, but there may also be kelpie in black costumes (reflective of dark undine) or with bodies that are as pink as the color of the water. (source: Personal communication with Kenkou Cross).
Just as they can freely run underwater, kelpie can also run upon the surface of water. (source: Personal communication with KC).

Kikimora usually see any fellow wives in a harem as equals. The only exception is if she was originally in the service of a monster girl noble, and said noble became a fellow wife. (source: Patreon Q and A).
In addition to the floppy ears KC gave the kikimora, the sheer volume of hair around the kikimora's head was meant to give her a dog-like look to contrast the bird features on other parts of her body. (source: Enty info article for the making of the kikimora profile).

Kraken
The dark object on a kraken's head is part of her body, but she can hide it using her mana (source: Personal communication with Kenkou).
Krakens are mysterious beings. Part of their "clothing" is actually a membrane their body grows, and part of it is real clothes they wear. But it is not clear where one ends and the other begins. (source: Patreon PM)
Krakens can massively increase the size and length of their tentacles, this is how they wrap them around ships while their humanoid body stays the same size. They can keep a ship in one piece while dragging it down by applying to the ship a field of protective mana that is similar to what is used on a man during sex to keep from harming him. (source: Patreon Q and A)
Krampus
Baphomet are much more powerful than krampus in both magical ability and physical strength, however, krampus have a special ability of becoming much stronger than normal on the "special days" they have designated in advance, to aid them in catching men. On these days they can do things such as open locked doors as if they were unlocked, or slide down chimneys they should not be able to fit through (and be completely unharmed if the fireplace is lit). They could of course simply break down a normal door to get into their target's home, but they do not do this as their focus is on the whole experience being a "gift" for the special occasion. (source: Personal communication with KC)
Kunoichi
The wings of kunoichi regressed to make it easier for them to move through tight spaces on their missions. Lack of wings don't hinder them due to how high they can jump, plus walk along walls and ceilings. They can even fly by using mudra hand signs to make mysterious giant kites appear on their backs (the kites aren't even tied to them but they can still fly with them). (Source: Kenkou’s Japanese Q and A)
The blade-like projections on her head are indeed her succubus horns. She feels pleasure from them being caressed just as other succubi do. As for wings, in most kunoichi there is not a trace of them on their body, but there may be some individuals that have small wings. (source: Personal communication with KC)
Ninjutsu can be learned by people other than kunoichi. In fact, kunoichi villages can also have monsters like inari and nekomata ninjas. (source: Personal communication with KC)

Lamia
Even in the age of the former mamono lords, monsters of the lamia and harpie families (among others) were still dependent on human men for reproduction. Normally there was no love involved, and once young were born the man would be eaten. However, in rare cases the monster would awaken to feelings of love and affection, overcoming her killing instincts and living with the man as something like a married couple. (source: Kenkou’s Japanese Q and A).
A human woman wearing the shed skin of a lamia family monster can turn into a lamia herself if the lamia has firmly embedded her mana into it. In exceptional cases the woman may become an echidna. (source: Kenkou’s Japanese Q and A).
The tongue of a lamia is a universal sensor that can detect not only the taste of her husband, but also determine temperature and distinguish smells! When she kisses, she naturally penetrates her husband's mouth with her tongue, receiving all the information about him, and intertwines with him to enjoy every inch of his body! (source: quote of KC tweet).
It seems that lamias spend at least ten minutes on one deep kiss. And they usually want to get another kiss in return. When kissing, these monster girls instinctively want to increase the number of places and the area of the body in contact with the husband - this leads to complete mess♥
Even a Medusa with a fairly low depravity, if you still kiss her, will turn bright red after the kiss. (source: quote of KC tweet).
Lamia villages can appear surprisingly normal in their treatment of male travelers, providing room and board via a village inn. However, a given room in the inn will often actually be "owned" by a unmarried lamia, and the man who stays in the inn will often have been selected by a lamia as her mate by the time he enters the village, or even beforehand. The innkeeper will make sure the man stays in the room owned by that lamia. Unclaimed men may be put in "open rooms" and their information made available to all the lamia in the village. Each room has a "night crawling hole" that only a lamia can slither through to facilitate night time ravishing. (source: KC tweet).
Large Mouse
In total population large mice are among the most numerous monster girls. (source: Kenkou’s Japanese Q and A).
Lava Golem
Leanan Sidhe
Fairy Kingdoms exist in various places throughout the world, but are in another dimension and thus inaccessible by normal means (source: supplemental notes on the titania profile).
When monsters of this tiny size become able to give birth to incubi, the baby will be correspondingly tiny and grow to normal human size in the process of growing up. (source: Kenkou's 2015 Ask.fm page).
Lesser Succubus
If the husband wants it, lesser succubi can retain the furry covering on their body even after becoming full succubi (source: Kenkou’s Japanese Q and A).
Even if human women all become monsters, if there is demand for the look/nature of the lesser succubus then a new subspecies may emerge to cater to it (source: Kenkou’s Japanese Q and A).
Lich
A lich can make a new phylactery if the old one breaks.
The tombstone-like cross behind them is a homemade magical tool to enhance and stabilize their necromancy. It is not carried on her back but floats behind her. Further, individuals who died and were buried before reviving may use their own tombstone as material for such tools. (source: Machine translated Enty info article on the making of the lich profile).
Lilim
It is rumored that more than a hundred lilims have been born in the 1000 or so years since the current Mamono Lord came to power (source: Kenkou’s Q and A thread)
Lilim cannot transform human women into races that still exist as non-monsterized beings (forest elves and angels for instance), nor into races with special requirements for existing (such as changing a human into a lilim). (source: World Guide 1 Monsterization Column)
Only those human women who meet various requirements (mana level, the direction of her own desires, physical strength and such) can be transformed into high tier races such as dragons, baphomets and echidnas. It also uses up a great deal of the lilim’s own power, but as human women who can become high tier monsters are rare and extremely precious lilims will aggressively attempt to monsterize them whenever such women are encountered (source: World Guide 1 Monsterization Column)
The sphere lilims ride on is made of solidified mamono mana and they can make it appear or vanish with a wave of their hand (source: Kenkou Q and A thread)
All lilim have white hair, but some have other colors mixed in for a mesh or gradient effect (source: Kenkou’s Japanese Q and A).
Some lilim have beast-like horns or tails or arms covered in insect-like armor (source: Kenkou’s Japanese Q and A).
If a lilim gets serious, she can make a man she wants as her husband orgasm just from her presence alone. (source: Personal communication with Kenkou Cross).
What a lilim gives birth to varies depending on the power level of herself and her husband. The daughter is usually a succubus or arch succubus, but if both the lilim and husband have accumulated a great deal of power during their marriage then the daughter may be a lilim. (source: Personal communication with Kenkou Cross).
Liliraune
Members of the alraune family can pull up the roots of their flowers if they want/need to move about (source: KC’s notes on the barometz).
Due to the above, the husbands of alraune family monsters can even hold desk jobs, though their wives may distract them (source: PM from Exet_mos).
By adjusting the size and shape of their flower and the angle of the petals, alraune monsters can sit down as if on a couch or lie down like on a bed, in short they are not stuck in a standing position. (source: Kenkou's 2015 Ask.fm page).
Living Armor
Living armor can get pregnant, and they give birth to fairly normal-looking children. However, as the child grows she will develop the armor over time as it sort of grows out of her body. This is at least in part due to how uncomfortable giving birth to a armored baby would be. (source: Response to questions on a "Making of" article on Enty, summary translation posted on 4chan, KC&Will_Book_Launch_Q&A).
The armor is designed to be unisex so that men can wear it, however, it is possible for a living armor to shapeshift her armor to a sexier, female design when she is not being worn. She can also make parts of the armor disappear, to make it easier to have sex with her while she is wearing the armor.

Malef dragons do not breathe normal dragon fire, but instead a black flame that is highly invasive to mana and strong against dragon fire. If the two flame attacks are used against each other, the black flame swallows up the dragon flame. (source: Patreon Q and A).
Those hit by the flame (often men targeted to become the husband of a malef dragon or dragonewt) will have it cling to them like an aura of darkness. The fire is fueled by their desires, and can’t be extinguished until they fulfill their sexual desires. (source: Patreon Q and A).
Malef dragons do not oppose the extremist faction and may ally with them at times, but they will not be subordinate to them as their mindsets are somewhat different (i.e. their focus is squarely on dragon reproduction and prosperity with their husbands). A malef may join the extremists as a guest general. (source: Patreon Q and A).
There is a legend in the MGE world about the mamono lord who was the progenitor of the malef dragon race. Known as "Draco-Mamono Lord Malef" he was slain in battle by the hero of that era. The hero was sprayed with the dragon’s blood, and Malef cursed the hero to never grow old or die. As the dragon died, he swore to the hero he would appear before him again one day. (source: Patreon Q and A).
There is also a more recent rumor related to the legend. Namely, it is said that somewhere in the world, in a secluded place, lives a mysterious sage who is knowledgeable of an ancient age when dragons controlled the world. He possesses great skill in swordsmanship, and is always accompanied by his beautiful wife, a dragon with black scales. They are said to spend their time sometimes fighting on such a scale that the very landscape changes, and other times in a friendly mating frenzy. (source: Patreon Q and A).
There is a bit of a story regarding the malef dragon pictured in the profile. She was originally a normal dragon, worshiped as a dragon god by the people of a human nation who had a dragon as their god. She fell in love with a man who was charged with protecting her, but due to her serious nature she was faithful to her role as a god and suppressed her feelings. However, an incident led to her changing into a malef dragon, and her in turn fulfilling her love to her guardian and turning the nation into a evil dragon kingdom. She is still worshiped as a dragon god by the people, who are overjoyed to have been welcomed into her family. (source: Making of Malef Dragon article on Patreon).
Mandragora
The mandragora in the profile art has leaves growing below where she was buried because it has been some time since she was pulled out of the ground. (source: Kenkou's 2015 Ask.fm page).
Man-eater (general info)
Man-eater (Claustrophyte)
In addition to climbing and crawling, the claustrophyte's two coiled vines allow her to hop and leap about. Each vine connects with a different side of the flytrap and then emerges again to coil up with the other below the flytrap. In other words, the flytrap jaws themselves are a giant leaf growing out of the vines (source: Personal communication with Kenkou Cross).
When a man is closed up in the giant leaves, the leaves make chewing motions along with the passionate motions of the couple inside, making it look from the outside like he is being eaten. (source: Personal communication with Kenkou Cross).
The sleeve-like structures are leaves and part of the body. Though they look sharp due to being pointy they are soft. These leaves also produce the digestive juices. They like to use these arm leaves to bite onto a man's arms, spread their juices on his skin while holding hands, and not let go. They can of course taste him like this too, and very much enjoy it. (source: Personal communication with Kenkou Cross).
Man-eater (Saccophyte)
Her straight hair is split into two large tresses, each tress growing out into a large vine used for locomotion. The two vines merge together below to form the pouch/bag the saccophyte is sitting in. The vines are shown hooked because the individual is hanging from a tree branch.
The structure underneath their breasts itself imitates a pitcher plant, complete with a cap leaf that opens up (the cap on the man eater herself being the large leaf growing from the saccophyte's head like a hat) to a red, heart-shaped part that imitates the bag of a pitcher plant (though there is no bag as it is flat against the skin of their abdomen). From this part flows out more digestive juices than what the rest of their skin can excrete, letting them readily soak their and their lover's lower bodies in it. (source: Personal communication with Kenkou Cross).
Depending on the individual and her mood (i.e. if she wants to show off her husband and their lovemaking to others or not), the saccophyte's bag can be made see-through enough to see a silhouette, or change to completely block vision from the outside. (source: Personal communication with Kenkou Cross).
While it can't be seen in the image, the red color on the profile saccophyte's legs continues uninterrupted to the tips of her toes. (source: Personal communication with Kenkou Cross).
Manticore
Manticore tend to be close to the average human man in height. (source: Subscribestar reply)
Mantis
The mantis is indeed "probably" not wearing any clothes aside from the red ribbon that she wears as an accessory. The rest of her "outfit" is like an outer shell, and she'll use the typical "magical erasure" ability of monsters to get rid of this shell when wearing actual clothes. (source: Personal communication with Kenkou).
March Hare
Matango
There are many varieties of matango and myconid that look like different kinds of mushrooms (albeit, not every kind of real world mushroom exists in the encylopedia world), including a matango variant that looks like the undead lamentation mushroom and turns men who inhale the spores into undead. (personal communication with Kenkou Cross).
Medusa
Things petrified by a medusa's eyes are filled with a magical power of protection such that even if someone beats on the stone it will not crack or chip. This power could conceivably be used to protect buildings as well. (source: Kenkou's 2015 Ask.fm page).
It seems that lamias spend at least ten minutes on one deep kiss. And they usually want to get another kiss in return. When kissing, these monster girls instinctively want to increase the number of places and the area of the body in contact with the husband - this leads to complete mess♥
Even a Medusa with a fairly low depravity, if you still kiss her, will turn bright red after the kiss. (source: quote of KC tweet).
Mermaid
Mermaids can move on land in three ways: crawling on their tails, learning spells of human transformation, or learning how to use their mana to hover off the ground (though this doesn’t mean they can fly freely through the sky). (Source: Kenkou’s Q and A thread).
Merrow

Mershark
The properties of mamono realm silver (damaging mana instead of the physical body) cannot be turned off as they are an inherent aspect of the metal. However, while the teeth of mersharks exhibit similar properties, this is caused by the mana imbued into their teeth rather than the material of the teeth themselves. Thus, if a mershark wants, she can simply cut off the flow of mana in her teeth and stop the mamono realm silver effect, enabling her to bite and eat normal meat. (source: Personal communication with Kenkou Cross).
She wears no real clothing, the blue armor around her chest and lower abdomen being natural growths of her scales that she can of course erase during sex. She also wears various tooth-shaped decorations on her wrists, arms, hair and around her neck. (source: Enty info article for the making of the mershark profile).
Like with real sharks, her teeth are fairly easy to remove but grow back quickly. They're often used as materials in accessories, and they sometimes give them as symbolic gifts to men, giving him a part of themselves. These teeth can also be forged into weapons that have a similar effect to mamono real silver thanks to the mershark mana in them. Further, women cut by such weapons (or attacked by a actual mershark) will often end up monsterizing into a sea dwelling monster themselves, such as a mermaid, nereid or another mershark. (source: Enty info article for the making of the mershark profile).
Mershark skin differs in roughness depending on color. The white parts of her skin are smoother, the blue rougher. (source: Comments related to Enty info article for the making of the mershark profile).
Mimic
Mimics and jinns of the jar do not have a single dedicated chest/jar of their own. Indeed they are born without any. Rather, they make ordinary chests/jars into parts of themselves. They may have favorites among this collection, and also change their chest/jar every day like changing clothes. A husband giving them a new chest/jar is often considered a good gift. (source: Patreon Q and A)
Mindflayer
Despite not serving the Mamono Lord, mindflayers generally get along well with other monsters. By using their mind-altering abilities they can fulfill various sexual fantasies for couples who request it (such as making the man think he is a orc from the age of the former Mamono Lord and making the monster think she is a human knight being attacked by him), and can function well as marriage counselors (source: Kenkou tweet).
The mindflayer's brainwashing will not work to make a monster cheat on her mate. In the first place they wouldn't use their abilities for this, and in the second a brainwashed monster would return to normal as soon as a man who wasn't her husband touched her in a sexual situation (source: Kenkou tweet).
A mindflayer husband in his squid form can in rare cases be big enough to wrap up his wife in his tentacles. (source: Personal communication with KC).
Minotaur
Unlike holstaurs, minotaurs will not naturally lactate unless they are pregnant or have a baby (source: Kenkou Q and A thread).
Mothman
Mummy
Mummies that accumulate enough mana transform into higher rank undead that appear very much like pharaohs. (source: Patreon Q and A).
Myconid
She does not wear clothes, her privates being covered by semi=transparent hyphae. (source: Making of Myconid article on Patreon).
The frills on her body are edible, do not feel pain, and regrow after some time if eaten. The frills on her arms are especially delicious. (source: Making of Myconid article on Patreon).
Myconids usually have small bodies compared to the typically large and voluptuous matango, likely as a consequence of how active they are. However, they still often have large breasts, perhaps as a shock absorber for their habit of launching themselves at men, or to make a man more comfortable when they cling to him. (source: Making of Myconid article on Patreon).
There are many varieties of matango and myconid that look like different kinds of mushrooms (albeit, not every kind of real world mushroom exists in the encylopedia world), including a matango variant that looks like the undead lamentation mushroom and turns men who inhale the spores into undead.

Even when a mad hatter's hat becomes a normal hat when a man wears it, it will change back into a mushroom hat if a human woman puts it on (source: Kenkou’s Japanese Q and A).
If stripped naked a mad hatter will still produce spores. Even her saliva will produce spores when one is kissing her (source: Kenkou’s Japanese Q and A).

Man-eater (general info)
Spoiler
While the effect is weaker than with alraune nectar, the scent and sensation of inhaling the vaporized digestive fluids of a man-eater still have a luring aspect. The man will feel pleasure from it, and likely follow the scent rather than just wander randomly in a daze. (source: Personal communication with Kenkou Cross).
Man-eaters are quite happy to simply carry their husband around in their trap if he wants to go somewhere. (source: Personal communication with Kenkou Cross).
Man-eaters are very dexterous and very strong with their vines from their hair. They can climb to high places with ease as well as crawl about with them on the ground. (source: Personal communication with Kenkou Cross).
That said, they can also easily walk around on their humanoid legs. To do this they use a simple version of the anthropomorphosis spell to temporarily erase the large plant part of them only. (source: Personal communication with Kenkou Cross).
For every man-eater, the large plant portion (the trap) is fused with their vine hair, said hair being a fully functional organ like a limb that they have full control over. The hair is split into two large vines, each vine connected to one side of their large trap. They recline in their trap but are not physically connected to it aside from by their hair vines. (source: Personal communication with Kenkou Cross).
When it comes to their overall designs, the man-eaters focus on a spiky-looking exterior that is still not too sharp, and a interior (and humanoid form) that is exceptionally soft and comfortable to be pressed up against. Them being so voluptuous/hourglass shaped is also to accentuate this. (source: Personal communication with Kenkou Cross).
Alraunes don't like letting letting their husbands out of their flowers/separating either, but the feeling is much stronger for man-eaters. (source: Personal communication with Kenkou Cross).
In places where man-eaters grow in large numbers, one can imagine all the vaporized digestive fluids create a incredible atmosphere full of steam. (source: Personal communication with Kenkou Cross).
Man-eaters can control the firmness of their digestive fluid to an extent. It's not that they can make it hard, but they can make the film along the surface of the fluid firmer/less permeable. (source: Personal communication with Kenkou Cross).
Man-eaters generally prefer to live in forests, but there are some individuals who have adapted to living in cities. (source: Personal communication with Kenkou Cross).
While they will let their husband out if he asks, they will be compelled to put him back in as soon as possible or cling to him with their arms. So effective methods for a man-eater husband to spend time outside the trap are mainly two things:
1. Master doppelganger medicine so that one clone stays inside the trap while the other moves about. Effectively the man is in two places at once, and perceives it this way, so it takes training/practice to handle it mentally.
2. Having the man-eater use anthropomorphosis. She can be satisfied for a time simply walking around holding onto his hand or arm, and this is actually a common sight with man eater couples. Of course, such contact is arousing too, and too much arousal will undo the transformation, so the couple will have to take regular breaks in alleyways and rest stops to release pent-up desire. (source: Personal communication with Kenkou Cross).
Husbands of man-eaters can keep their clothing and accessories intact by the use of enchantment magic to make them invulnerable to the man-eater's fluids. They can also weave clothes using fibers from the vines and leaves of the man-eater herself, as these parts are innately immune to her fluids (they will grow back so like with mandragora it is no problem to cut them a little). (source: Personal communication with Kenkou Cross).
These clothes, however, are for the husband. Man-eaters themselves prefer to expose as much bare skin as possible, and thus usually wear no clothing at all, in order to keep their bodies as close to their prey as possible. The protection offered by their trap means they have little use for extra protection (i.e. clothing) from the elements. That said this does not mean they do not like to "dress up" and look good for their husband. The profile claustrophyte carefully styles her hair for this purpose, while the profile saccophyte decorates her hair and large head leaf with flowers she gets to accentuate her beauty. (source: Personal communication with Kenkou Cross).
The traps of man-eaters swell up/stretch in order to match the size of their and their husband's bodies. (source: Personal communication with Kenkou Cross).
Also applicable to incubi in general, but the reason that the husbands of man-eaters become able to be clear-minded enough to negotiate being let out of the man eater's trap in the first place is because, when they become incubi, their ability to tolerate pleasure becomes much higher than a normal human. This is similar to how monsters can enjoy pleasures that for a human would be too much to stay conscious for. Some studious monsters even think more clearly and progress in research better when they are immersed in extreme pleasure. The adjustment is more gradual for a incubus, but the man over time becomes able to focus and discuss things to a degree despite the pleasurable effects of the man-eater's digestive fluids being just as potent, satisfying and effective on him as ever. The incubus' pleasure = mental focus effect basically becomes able to counter the man-eater fluid's loss of focus effect. (source: Personal communication with Kenkou Cross).

The nekomata's ability to transform into a cat is instinctual, and they become able to do it right after they are born.

The female has wings and tail, but withdraws them so her mate can take over. Her wings' "hands" are smaller, more delicate, and end in claws. (source: Enty info article for the making of the night gaunt profile).
Regarding the suit, it is formed from a mucus she excretes that later firms up into the rubbery layer (though more mucus can still seep out through it). The mucus releases some magical light of its own, while her tail and horns also glow with a soft light. The female body produces the most mucus from her fingertips and breasts, making these glow as well. The purple smoke emanating from her is produced from excess mana burning off. Touching it would likely coat you in mucus. (source: Enty info article for the making of the night gaunt profile).
The tip of the tail is sharp, but (as seen in the profile) can open up to reveal another tail that releases a lot of mucus. It can even shoot the mucus (this speaks of the male's tail but it's not clarified if this only applies to the male's tail). (source: Enty info article for the making of the night gaunt profile).
Nightmare
The scythe a nightmare carries is used to cut an opening into the dream world. However, they don't actually need the scythe to do this. For nightmares the scythes are something like fashion items handed down from ancient times (source: Kenkou’s Japanese Q and A).
The principle is not well understood but the magic of a nightmare appears to temporarily create a space similar to a spirit realm whenever she enters a dream. Thus every dream she enters temporarily becomes its own small world she can exist in. (source: Personal communication with Kenkou Cross).
Nurarihyon
They are designed to give opposing impressions. On the one hand they have a "mob boss" look, as they can take charge of even rowdy monsters like oni. On the other, they have a side that is like a "head courtesan," ruling over enchanting monsters like inari and kejourou. (source: Enty info article for the making of the nurarihyon profile).
The darkness shrouding them barely reflects any light, and doesn't brighten even if light shines directly on it. Thus it is drawn with no shadows, like the sphere of a dark matter, with only purple highlights standing out. Her eyes show the same darkness. (source: Enty info article for the making of the nurarihyon profile).
KC acknowledges that her nipples logically should be visible, but that it's too obscene for a profile illustration and basically they're invisible for the sake of that (as noted in the settings guides, many monsters can freely disguise such parts of their bodies). (source: Enty info article for the making of the nurarihyon profile).
Nureonago
In addition to the normal slime ability to not make surfaces or objects wet unless they want to, nureonago can outright absorb moisture skillfully to dry laundry in an instant. (source: Kenkou's 2015 Ask.fm page).
The nekomata's ability to transform into a cat is instinctual, and they become able to do it right after they are born. However, in this case the cat they turn into will be just as helpless as their baby humanoid form, so nekomata usually don't start using their cat form until they have learned how to at least crawl.

Ocelomeh
Ocelomeh culture is not like the amazoness where common gender roles are reversed. It is most common for them to raise their daughters together equally with their husbands. This is partially rooted in the value they place on raising their children into warriors who are not ashamed to present themselves to the gods, and thus they set an example by hunting with them from an early age and demonstrating how to love a husband with animal lust daily. (source: Patreon Q and A).
The straps covering her nipples are noted to strangely not slip even during intense fighting. The weight on their loincloth normally keeps it from moving too much, but they may take the cloth in their mouth during sex to show off how they have joined with a man. (source: Making of Ocelomeh article on Patreon).
While they have many similarities to hellhounds, the source of their ferocity is different. Hellhounds are reverse rape supremacists due to the overwhelming intensity of their lust and urges, and the greatness of their strength. For the ocelomeh, there are also other factors. They are intellectual and cultural reverse rape supremacists due to their god's teachings, and rather obsessive about it. Of course, like all monsters, what is most important to them is not who is doing the ravishing but the simple fact that they are having sex with their husband. (source: Making of Ocelomeh article on Patreon).
Ochimusha
When they rise as undead, the regular sword of an ochimusha becomes a mamono realm silver weapon (source: Kenkou tweet).
While, as mentioned in the profile, it is still standard for men in Zipangu to be the heirs, clans there under female leadership who do not specify gender for heirs are increasing. (source: Enty info article for the making of the ochimusha profile).
When they rise as undead, the spot where the ochimusha received a fatal wound easily leaks mamono mana, causing the area to be dyed red like blood despite there being no wound anymore and them changing clothes. The profile ochimusha seems to have been killed by a wound to her chest. (source: Enty info article for the making of the ochimusha profile).
Their right arm's monstrous form would be inconvenient for daily life, so they normally keep it in a normal state like their regular other arm. The fierce transformed state is a partial release of a monstrous transformation. It is used for battle, and is similar in concept to how dragons can transform into their original forms. (source: Enty info article for the making of the ochimusha profile).
Ogre
Oomukade
Oomukades have a shell with centipede legs attached around their upper arms, though it is hard to see in the profile image. As with so many such parts, they often make it disappear during sex. (source: Patreon reply)
Orc
Overpowering an orc does not necessarily have to be through combat or sexual prowess; even for example trapping one and only letting her go once she submits can also count, as all that matters is that the orc ''feels'' "defeated". (''source'': Kenkou’s Japanese Q and A).
Regarding orc harems, there isn't much room for the possibility of some dominating the man while others are submissive. Generally it is one or the other. This is because if one orc starts to be dominant with him, the rest will join in on the behavior to have sex whenever they want with him. (source: Patreon reply).
Otohime
Otohime lack a typical breath weapon, but have supernatural control over water. A otohime can manipulate water currents to create a whirlpool, or form water in front of herself and launch it like a laser by letting the current "flow." (source: Personal communication with Kenkou).
The otohime's giant dragon form looks like a combination of a seahorse and a dragon and has flashy fins. (source: Personal communication with Kenkou).
Owl Mage
Like real owls, they can turn their heads almost completely around to look behind them, meaning you cannot avoid the power of her eyes by being behind one. One reason she was made with so much fluff on her neck was to reduce how scary it would be to see her neck contort like that. (source: Enty info article for the making of the owl mage profile).
The black on her hips and thighs is not skin but tights she is wearing, black tights suitable for a intellectual woman like a scholar or librarian. While the owl mage is still slightly short, she is regarded as a "medium-sized" race of harpy, and thus has larger breasts than some other kinds.

Papillon
Her design is meant to contrast the high inhumanity of the greenworm's look, as well as the fluffy and "thick" look of the mothman. (source: Machine translated Enty info article for the making of the papillon profile).
The profile greenworm and papillon are the same individual, so various points of similarity were put into the design. Namely they have roughly the same hairstyle, the "hairband-like" structure is the same, and the shape and patterning in the eyes are the same. (source: Machine translated Enty info article for the making of the papillon profile).
Near as I can tell, all her clothing (her tie, shawl, sleeves, skirt, apron, and boots) is actual clothing, just designed with a butterfly/insect appearance. (source: Machine translated Enty info article for the making of the papillon profile).
They have a strong desire to suck their husband's members, and are as hungry for sex as a greenworm is for food, but they don't show it in public. They carry so much flower nectar around in their apron pocket as a way to distract themselves from this hunger when in public. (source: Machine translated Enty info article for the making of the papillon profile).
Parasite Slime/Slime Carrier
Parasite slimes initially have no ego/personality, being comparable to a brain-lacking animal like a jellyfish, and function off instinct. However, they gain a personality via their host, as they become one and the same being in a sense. While it is identical, their ego is expressed independently, and they are capable of their own thoughts and actions. And just as the host's mind becomes the mind of the parasite, the parasite's instinctual desires become part of the host, causing them to think like a mamono. (source: Patreon Q and A).
Parasite slime jelly has a peach flavor. Women who eat it will transform into slime carriers. (source: Kenkou's 2015 Ask.fm page).
Phantom
Since their body is made of mana and not wearing actual clothes, KC deliberately designed the phantom's clothes to look like they are fused with her, and by further manipulating her spiritual body she can "undress". While they have no legs in the profile art, they can transform their their wispy lower body to give themselves legs to some extent. (source: Enty info article for the making of the phantom profile).
The bicorn and arch imp profile arts depict the same individual unicorn and imp after she has evolved/transformed. However, the ghost is a different individual. (source: Enty info article for the making of the phantom profile).
Pharaoh
Most of the pharaohs were originally male and became female when they became monsters (source: Kenkou’s Japanese Q and A).
The cobra pictured with the pharaoh is a type of mamono realm beast. They are calm and smart creatures, and by using the pharaoh’s mamono mana they can be used as weapons or assist her in using magic (source: Kenkou’s Q and A topic).
While pharaohs bitten by an apophis will give up their throne in favor of spending even more time having sex, they aren’t stuck in their rooms and may even continue to assist in governing the realm (source: PM from Exet_mos and KC).
To stop a apophis from attacking a married pharaoh, the couple only need to show that they indulge in friendly sex together like a monster couple. The apophis loses her will/instinct to attack if she sees that the pharaoh is already a lecherous monster (source Patreon PM from KC).
The massive amount of mana in the pharaoh's body leaking out is what causes a slight reddish glow in the cracks in her skin. Despite the cracks, her of skin is of course soft and pleasant thanks to the benefits of them being part succubi. The cracks may have their own magical effect, as indicated by the heart-shape they form on her shoulder. (source: Enty info article for the making of the pharaoh profile).
The golden serpents coiled around her arms are accessories made of gold. They are able to move like real snakes, and the cloth tied to the snakes will shift and flow with them. It gives every movement a pharaoh makes an added grace as if they were dancing, adding to their graceful and lewd appearance. (source: Enty info article for the making of the pharaoh profile).
Phoenix
Harpies all have clawed hands that are normally hidden within the feathers of their wings. (source: Ghandharva profile art, also KC&Will Book Launch Q&A).
Many phoenixes have a liking for/familarity with the undead kingdoms and enjoy visiting them. This is because undead are also in effect immortal, and thus the phoenix might see familiar faces even if it has been centuries since the last visit. (source: Personal communication with Kenkou Cross).
The furry decorations and ribbons are designed after the tails of fiery birds of folklore, and them making it look like the phoenix has human arms at first is an intentional illusion on the part of KC. (source: Making of Pyrow and Phoenix article on Patreon).
Unmarried phoenix will disguise themselves as human-like creatures using anthropomorphosis and join with groups of pyrows to search a city for men. Thus it can be said that their image as a divine bird is maintained because when they attack men and show their hedonistic side they are often in disguise. It is also rumored that they adopt such disguises because they dislike being treated so formally, but it is uncertain how much this applies since there are so few phoenixes. (source: Making of Pyrow and Phoenix article on Patreon).

Queen Slime
Other types of slime can be born with the mutation that allows them to become their own type of queen slime, but for higher rank slime races this is very rare (source: Kenkou’s Q and A topic).
Slimes tend to only realize they have the queen slime mutation when they first try to divide and discover they cannot fully do so. (source: Kenkou's 2015 Ask.fm page).
Regarding how their divisions function, they are normally tethered by slime to the main body. However, if this line is broken they can continue to function independently until they run out of mana, so they won't collapse immediately. When empowered by their husband's semen they can function for longer. However, there is a range limit and if a disconnected slime exceeds this limit (or runs out of mana before being reconnected) then she will collapse into a lifeless puddle of just slime. However, the division is not "dead" and will revive back at the main body with full memory of what transpired. How far a disconnected division can go from the main body is dependent on the strength of the individual. (source: Personal communication with Kenkou).

Raiju
The glowing triangular objects on the raiju's clothes may look artificial but they are a part of her and function as "electrodes." When not charged they are a metallic black ash in color. They can manipulate them in various ways such as to apply pressure when discharging electricity. That said, their whole body is electrified so one can be shocked even if they avoid the electrodes (source: Kenkou tweet). Perentie note: To me this implies they are mana constructs.
Incubi won't gain special abilities like lightning powers and extreme speed from a raiju simply by being married to her. However, he may gain visual acuity to a level that lets him track her high speed movements, as well as resistance to damage caused by lightning. (source: Patreon Q and A).

It is not just their hats that change when they are engorged with their husband's mana.

Red Slime
Ren Xiongmao
They enjoy many kinds of games, including one played with a stick that is similar to billiards. With their husband they will play many kinds of silly games with sexy consequences, basically of the “if I win I do what I want with you,” and “if you win you do what you want with me,” and she may lose on purpose depending on her mood.
Roper
Roper can reproduce without a human woman to infect. In this case the roper conceives a humanoid baby and the baby becomes host to a roper seed while in the womb, and thus is born as a roper (source: Kenkou’s Japanese Q and A).
Ryu
Ryu are generally calm and kind, but their pride as a "water goddess" means they have an unusual trigger for their temper. Namely, being seen taking a bath will enrage them, as they consider the need to clean themselves an insult to their pride. If the one who sees her is either her husband or (if she is unmarried) a suitable man, her anger will turn to lust and she will exhaust the culprit until she is satisfied.

(source: Machine translated Enty info article on the making of the redcap profile).
Red Slime
Ren Xiongmao
They enjoy many kinds of games, including one played with a stick that is similar to billiards. With their husband they will play many kinds of silly games with sexy consequences, basically of the “if I win I do what I want with you,” and “if you win you do what you want with me,” and she may lose on purpose depending on her mood.
Roper
Roper can reproduce without a human woman to infect. In this case the roper conceives a humanoid baby and the baby becomes host to a roper seed while in the womb, and thus is born as a roper (source: Kenkou’s Japanese Q and A).
Ryu
Ryu are generally calm and kind, but their pride as a "water goddess" means they have an unusual trigger for their temper. Namely, being seen taking a bath will enrage them, as they consider the need to clean themselves an insult to their pride. If the one who sees her is either her husband or (if she is unmarried) a suitable man, her anger will turn to lust and she will exhaust the culprit until she is satisfied. (Source: Dragonia - Basic Information Guide)
The "hands" covering the ryu's breasts are not hands but scales that grow in the shape of hands. (source: Patreon PM)
Ryu lack a typical breath weapon, but have supernatural control over water. A ryu can form a simple rain cloud and shoot water from it. (source: Personal communication with Kenkou).
Spoiler
Sahuagin
Like the kappa, a sahuagin's "swimsuit" is in fact just the form her scales take as they grow out from her body, though it seems it can be shed and made into suits worn by other monsters (source: World Guide 1 Monster's Clothes, and Kappa book profile).
The sahuagins scale swimsuit is normally blue, but very rare white swimsuits may also exist (source: Kenkou’s Japanese Q and A).
One can add embroidery to the scale swimsuit of a sahuagin (source: Kenkou’s Japanese Q and A).
Salamander
Salamanders do not have a particular location to touch to arouse them, rather they are aroused in general by physical contact, as if kindling a fire. As well as sparring with them, a game that requires a lot of physical contact will lead to them pushing the man down to have their way with him. (source: Patreon Q and A).
Salpinx
Sandworm
By developing their mamono mana and intelligence over time via being married, a sandworm can learn how to shrink her shell down to the point that she looks rather like a lamia, allowing her to go into towns with her husband. She can also learn to morph the parts of her body attached to the inner worm flesh to make them look more human, however she cannot actually detach herself from the shell (source: Kenkou’s Q and A topic).
It is possible for a sandworm to use the control she has over her shell's flesh to create closed off, dry rooms (mostly for her husband to store things), as well as fleshy equivalents of beds or benches (source: Kenkou’s Japanese Q and A)..
The interior of a sandworm can emit a magical light for visibility (source: Kenkou tweet).
To reproduce, the female body within the shell lays an egg. The baby sandworm has a small/fragile shell after hatching and so both parents will raise her inside the mother's shell until she grows larger.(source: Kenkou’s Japanese Q and A).
When freely flowing the hair of a sandworm feels like damp human hair, but if bound together it will have a texture like a tongue. The sandworm can freely control her hair to bind or unbind it (source: Kenkou’s Japanese Q and A).
While a sandworm must remain attached to her outer shell, the attachment point can be freely moved to anywhere on the body. This can allow her to fully form legs and have the attachment to her outer shell become something like a tail (source: Kenkou’s Japanese Q and A).
There is a fairly expensive magic item called the "Sandworm Outing Ring" that can be purchased for use by monsters like sandworms. It is a ring fitted in the middle of the outer shell, which causes the body below that point to enter a pocket dimension. This allows the sandworm to move through ground outside a desert without digging it up, ruining roads, etc. Sandworm couples often make heavy use of mana cages to afford this item. (source: Kenkou tweet).
Scylla
Sea Bishop
Mermaids can move on land in three ways: crawling on their tails, learning spells of human transformation, or learning how to use their mana to hover off the ground (though this doesn’t mean they can fly freely through the sky). (Source: Kenkou’s Q and A thread).
Sea Slime
Selkie
Just as we are typically born with little hair, when a selkie is born she has no pelt at all, but it appears on her body before long and grows along with her. When not wearing the pelt they are very difficult to tell apart from humans. Their ears, while not visible in the profile illustration, are rounded just like a human's. (source: Subscribestar reply)
Shirohebi
Despite their jealous natures shirohebi can become part of a harem and one way or another get along with them. However they will make every effort to become the dominant wife and get the most sex. Things can get quite rough for the husband's body as the harem gets very busy until things are settled (source: Kenkou’s Japanese Q and A).
There are many ways monsters can use to pour mana into someone. In terms of efficiency, it is sexual intercourse > > mouth-to-mouth, claws and fangs > > physical contact > > pouring mana. By their nature shirohebi favor mouth-to-mouth, physical contact (such as stroking his lower abdomen), and pouring mana into him via their breath and words as they whisper into his ear. (source: Kenkou's 2015 Ask.fm page).
Since she starts fires of lust only to put them out with her own "water," KC refers to her as a "match-pump" monster girl. This is a Japanese idiom that refers to someone who starts a problem so they can solve it for their own benefit (the pump referring to a water pump). (source: Enty info article on the making of the shirohebi profile).
Shoggoth
The main body of the shoggoth is vulnerable to fire, but objects they create that are meant to handle fire do so just fine. (source: Kenkou tweet).
Objects created from a shoggoth's body can last quite some time, but normally she absorbs them back in once they are no longer in use. (source: Kenkou tweet).
Shoggoths dislike having anyone other than their husband use objects made from their body and receive no pleasure from it. Thus they will usually serve guests using normal objects from the market and such. (source: Kenkou tweet).
A man married to a shoggoth can experience the same benefits of his transformed body (body mixing, sexual pleasure from simple touches and such) when interacting with other slime family monsters. (source: Kenkou tweet).
Shoggoths won't let anyone but their husband eat their jelly. It has a taste that is indescribable in the English or Japanese language. If a man eats an unmarried shoggoth's jelly they will be targeted as a future husband. (source: KC&Will Book Launch Q&A).
The heart-shaped structure around the position of their womb glows more strongly and mysteriously when she feels intense love and devotion toward her master, or when she is in heat. (source: Machine translated Enty info article on the making of the shoggoth profile).
Basically, what shoggoths intended when imitating their creators was to create a continuous connection when mating, two bodies creating a whole. However, instead their husband becomes the same slime as themselves, resulting in them mixing together at the height of intercourse rather than being connected. However, the shoggoth are not dissatisfied by this result at all. To clarify, the husband does mostly remain in human form, but at climax he and the shoggoth may become mixed together like a giant slime, the profile's reference to the lines between them being blurred, their genitals mixing together, etc. being a description of this. (source: Personal communication with KC)
Selkie
Siren
Harpies all have clawed hands that are normally hidden within the feathers of their wings. (source: Ghandharva profile art, also KC&Will Book Launch Q&A).
Skeleton
Slime
For any slime monster girl the whole body is an erogenous zone. They can also concentrate sexual sensation to any part of their body at will, and will try to do so wherever their husband inserts. (source: Kenkou's 2015 Ask.fm page).
Soldier Beetle
The weapons the beetle holds are part of her body but she can put them away should she need to use her hands for erotic things and such (source: KC’s notes on the soldier beetle).
Regarding what it looks like when a soldier beetle "puts away" their shield and weapon, they basically fold up to become smaller and then disappear. Interestingly, the soldier beetle often accompanies this effect by moving as if she was stowing normal weapons and armor away. (source: Personal communication with KC).
Sphinx
Succubus
These are among the races known to have in rare cases overcome their human-killing instincts and fallen in love with humans in the age of the former mamono lords. (source: Kenkou’s Japanese Q and A).
Related to the above, there is an old story of a princess who was transformed into a succubus and captured a man she had loved as a human. Her feelings remained and she continued to love him. (source: Patreon Q and A).
Succubi have lifespans that range from several hundred to several thousand years depending on the individual. The Mamono Lord may have a potential lifespan exceeding 10,000 years. (source: Kenkou’s Japanese Q and A).

Salpinx
Spoiler
The salpinx's clothes are mysterious. Despite being completely open in front her nipples are just barely hidden by her clothes when she stands and moves about. The same goes for her lower privates. They are designed to evoke images of a peaceful moonlit night, bedrooms, and pajamas. (source: Personal communication with KC)
The mass that fell from the sky mentioned in the profile was originally something that would have turned the water bitter and caused a fever and death, their bodies turning white like burnt ash. Due to the salpinx's powers, the mass was replaced with a different mass that originated from the abyssal monsters. To some extent what form the disaster they transform takes is determined by what the disaster originally was going to be as well as the scale of the original disaster, and the salpinx has no willful control over it. In fact, should the result be large-scale monsterization they may look surprised or somewhat apologetic (though also aroused at the sights). (source: Personal communication with KC)
The detachable pieces of the trumpet seen in the art move in time with the music and performance and may have a role in tuning the sound of intervening in the disaster. (source: Personal communication with KC)
While the salpinx's preferred pose is suited to lying down and lazing about, they have angel mentalities so many are actually earnest and hardworking. On the other hand, they like to make their husbands so happy that they don't let them get out of bed and end up spending all day in bed with him enjoying sex. (source: Personal communication with KC)
Regarding their relationship with the extremist faction, their ideals do not quite align. The salpinx do not have a goal to turn the world into a mamono realm or all human women into monsters, they simply seek to make the world a place where disasters are prevented. However, their interests are aligned with the extremists in the sense that they both seek to prevent disasters and tragedies in human lands, so they tend to cooperate and get along well. (source: Personal communication with KC)
Which deity they served before becoming monsters is a secret for the time being. Their four wings mark them as mid-rank angels like the valkyries and cupids. That there is still white in their wings is indicative of how their mentality hasn't changed much since becoming monster girls, they simply became a little lewd. Originally their wings were all white, their skin pale, changing to what we see in the profile when they became monster girls. (source: Personal communication with KC)
The design of their trumpets changed when they became monster girls, namely gaining the heart designs. That said, the seven distinct pieces lining their trumpets were originally present, and may hold some meaning. Called "The Trumpet of the End," these trumpets are ancient relics that appear from out of nowhere whenever a new salpinx is born. The exact mechanisms of how the trumpets work are a mystery. (source: Personal communication with KC)
The intent behind the design of their eyes was to be blazing and bewitching, but also calm and peaceful to show their inner selves despite being fallen angels. The ring on their arm is like the halos of other angels, a massive concentration of angelic power given form. The ring is on their arm instead of their head because it helps them put their energy into their performances. Their necklace is also made of this angelic energy. (source: Personal communication with KC)
The false stories of them causing disasters originate in part due to people not knowing something much worse would have happened if they hadn't intervened, and in part due to observers simply finding the red light from their trumpets ominous and disturbing. (source: Personal communication with KC)
They are not allied with the fallen god, having become monster girls with a firm purpose distinct from that of the fallen god's angels (and while they are under the authority of the Mamono Lord, they do not actively serve her either). In behavior and looks, the salpinx are meant to be lewd and revealing, but not vulgar, still giving an elegant and pure impression. (source: Personal communication with KC)
Animals normally cannot become monster girls, so the event the profile described where this happened was something of a miracle and may have resulted in a new species being born.
The salpinx in the profile is the size of a normal human. The trumpets they use are just very large. (source: Personal communication with KC)
Their husbands often feel like meeting them was fate, as they come upon the bewitching beauty after passing through a calamity. The salpinx is not surprised though, to her she knew he would come, that if it were anyone it would be him. It is a uncertain if she is guiding him or if it is fate.

Taisui
The profile has her giving a "hugging pose" because a man under the influence of her powers tends bury his face in her breasts, so she uses her big hands to hold him close. (source: Personal communication with Kenkou Cross).
The knowledge hakutaku possess is not inferior to taisui, but it is different. Hakutaku knowledge is focused on what is applicable even in modern times, lost secret techniques, trivial trivia, etc. whereas taisui knowledge is focused on things that can be considered unknown knowledge, knowledge that has not been used by monsters or humans of any era (an example given being Ropurotto's personal secret, or how to make a secret medicine using mucus toad mucus). However, while their understanding will be incomplete, hakutaku are perhaps second only to a taisui's husband in being able to decipher and understand the knowledge taisui have. (source: Ochiverde personal communication with Kenkou).
Unlike regular slimes, who instinctively form appealing clothes, Taisui does so conciously. (source: Ochiverde personal communication with Kenkou).
They are the type who knows things that nobody else knows, but lacks the general knowledge that everybody else knows and has to be taken care of by her husband. (source: Ochiverde personal communication with Kenkou).
Their appearance resembles abyssal demons. And in the Japanese text they have "knowledge of the depths". They may have knowledge of the abyss that cannot be reached by human knowledge. (source: Ochiverde personal communication with Kenkou).
They don't move underground in a random way, with so many eyes, maybe they can even see the red thread of fate and follow it. (source: Ochiverde personal communication with Kenkou).
Her costume is made out of the juice that excretes from her flesh. It doesn't naturally change colors. Some individuals may have unusual colors of juice, though. (source: Ochiverde personal communication with Kenkou).
Tentacle
Normally a human woman who has enough sex with a tentacle to monsterize will become a succubus. In rare cases a woman with particular affinity for a tentacle's mana may become a tentacle herself. (source: Kenkou’s Japanese Q and A).

Fairy Kingdoms exist in various places throughout the world, but are in another dimension and thus inaccessible by normal means (source: supplemental notes on the titania profile).

Tritonia
Tritonia come in many colors and patterns depending on the individual. The profile individual is based on Hypselodoris festiva. (source: Enty info article for the making of the tritonia profile).
Her feelers and tentacles are translucent, but glow in the dark and glow more brightly when they sense a man. The pattern on their forehead reflects their emotions to an extent, glowing more strongly when they are happy and being dull when they are sad. The heart-shaped pattern on their belly/womb glows brightly when they are sexually satisfied. (source: Enty info article for the making of the tritonia profile).
Troll
Trolls tend to be taller than average human men. (source: Subscribestar reply)
Trumpart
Diamond trumparts turning their husbands into animals is an example of the exciting things they like, but not an innate power they have. Rather they have to learn such magic. (source: Patreon Q and A).
The "biased" view the Queen of Hearts uses to select someone to become a trumpart is simply that she would like a particular human girl to be her friend. (source: Machine translated Enty info article on the making of the trumpart profile).
While they are given a certain number to start with, a trumpart is not set to always be that number. By training and getting stronger, accumulating mana, etc. they can rise in the ranks. The stronger the face card or ace, the fewer the individuals. (source: Machine translated Enty info article on the making of the trumpart profile).
Tsurara-onna
The eyepatch on the profile tsurara-onna is simply a normal eyepatch, she wears it for fashion. (source: Personal communication with Kenkou).
The ice growing out of the tsurara-onna's covered eye is simply where ice mana crystalizes easily in that individual. In others both eyes may be uncovered and ice will crystalize elsewhere. Even when covered though (by ice or an eyepatch), they can see through it just fine as their eyes work differently from normal creatures. (source: Personal communication with Kenkou).
In the original myths, tsurara-onna are beautiful humanoid incarnations of icicles that marry men but melt away when they take a bath, making them markedly milder (usually) than the often deadly yuki-onna. But since icicles suit a sharp, fierce personality, the tsura-onna in the encyclopedia world are aggressive and violent (in a sexually forward meaning) while the yuki-onna is seductive. (source: Enty info article for the making of the tsurara-onna profile).
As with other profiles, black sclera is a symbol of aggressive, "violent" monster races in the encyclopedia world. One way this manifests for the tsurara-onna is that (despite still having the mild and family-oriented nature of other Zipangu monsters) she will force things like homemade dishes and sexual services onto her husband, and is the sort to invite herself to be his wife. She is likewise drawn to show she is giving her husband an enraptured look, and also to be "evil-looking". (source: Enty info article for the making of the tsurara-onna profile).
The ice jutting from her breasts and arms continues around her back, forming a ring of icicles when she lowers her arms. (source: Enty info article for the making of the tsurara-onna profile).
All the icicles on her are formed from ice mana leaking from her body. Should she change clothes, they may get frozen in a similar way if she relaxes. The ice forming from left hip and right eye are noted to be erogenous zones, that transmit heat and pleasure to her womb and straight inside her head respectively when stroked or licked. (source: Enty info article for the making of the tsurara-onna profile).

Normally a human woman who has enough sex with a tentacle to monsterize will become a succubus. In rare cases a woman with particular affinity for a tentacle's mana may become a tentacle herself. (source: Kenkou’s Japanese Q and A).
Titania
Fairy Kingdoms exist in various places throughout the world, but are in another dimension and thus inaccessible by normal means (source: supplemental notes on the titania profile).
Thunderbird
Harpies all have clawed hands that are normally hidden within the feathers of their wings. (source: Ghandharva profile art, also KC&Will Book Launch Q&A).
Tritonia
Tritonia come in many colors and patterns depending on the individual. The profile individual is based on Hypselodoris festiva. (source: Enty info article for the making of the tritonia profile).
Her feelers and tentacles are translucent, but glow in the dark and glow more brightly when they sense a man. The pattern on their forehead reflects their emotions to an extent, glowing more strongly when they are happy and being dull when they are sad. The heart-shaped pattern on their belly/womb glows brightly when they are sexually satisfied. (source: Enty info article for the making of the tritonia profile).
Troll
Trolls tend to be taller than average human men. (source: Subscribestar reply)
Trumpart
Diamond trumparts turning their husbands into animals is an example of the exciting things they like, but not an innate power they have. Rather they have to learn such magic. (source: Patreon Q and A).
The "biased" view the Queen of Hearts uses to select someone to become a trumpart is simply that she would like a particular human girl to be her friend. (source: Machine translated Enty info article on the making of the trumpart profile).
While they are given a certain number to start with, a trumpart is not set to always be that number. By training and getting stronger, accumulating mana, etc. they can rise in the ranks. The stronger the face card or ace, the fewer the individuals. (source: Machine translated Enty info article on the making of the trumpart profile).
Tsurara-onna
The eyepatch on the profile tsurara-onna is simply a normal eyepatch, she wears it for fashion. (source: Personal communication with Kenkou).
The ice growing out of the tsurara-onna's covered eye is simply where ice mana crystalizes easily in that individual. In others both eyes may be uncovered and ice will crystalize elsewhere. Even when covered though (by ice or an eyepatch), they can see through it just fine as their eyes work differently from normal creatures. (source: Personal communication with Kenkou).
In the original myths, tsurara-onna are beautiful humanoid incarnations of icicles that marry men but melt away when they take a bath, making them markedly milder (usually) than the often deadly yuki-onna. But since icicles suit a sharp, fierce personality, the tsura-onna in the encyclopedia world are aggressive and violent (in a sexually forward meaning) while the yuki-onna is seductive. (source: Enty info article for the making of the tsurara-onna profile).
As with other profiles, black sclera is a symbol of aggressive, "violent" monster races in the encyclopedia world. One way this manifests for the tsurara-onna is that (despite still having the mild and family-oriented nature of other Zipangu monsters) she will force things like homemade dishes and sexual services onto her husband, and is the sort to invite herself to be his wife. She is likewise drawn to show she is giving her husband an enraptured look, and also to be "evil-looking". (source: Enty info article for the making of the tsurara-onna profile).
The ice jutting from her breasts and arms continues around her back, forming a ring of icicles when she lowers her arms. (source: Enty info article for the making of the tsurara-onna profile).
All the icicles on her are formed from ice mana leaking from her body. Should she change clothes, they may get frozen in a similar way if she relaxes. The ice forming from left hip and right eye are noted to be erogenous zones, that transmit heat and pleasure to her womb and straight inside her head respectively when stroked or licked. (source: Enty info article for the making of the tsurara-onna profile).
Spoiler
Umi-osho
The inspiration for the umi-osho being a masochist came from how the turtle in the myth she is based on is introduced being bullied by a group of children. (source: Enty info article for the making of the umi-osho profile).
The umi-osho's sleeves and socks are themed after turtle fins and scales (this implies her hands and feet look normal underneath). (source: Enty info article for the making of the umi-osho profile).
Unagi-joro
Regarding the unagi-joro's clothes, KC made note that her top is a film-like cloth deliberately designed to blend in with her skin and make it hard to tell if she is naked or clothed. Her "ludicrously revealing" kimono is clarified to not be simply sleeves but to wrap around behind her. (source: Enty info article for the making of the unagi-joro profile).
Undine
An undine's "skin" feels soft, softer than human skin, and could be compared to warm skin covering a body of water. They can adjust their permeability to be like a slime's or like water itself. (source: KC&Will Book Launch Q&A).
Unicorn
Unicorns cannot become bicorns simply from exposure to atmospheric mamono mana or the mana emitted from the body of another monster as her own mana will block and neutralize it. The foreign mamono mana must be put inside her along with her husband's essence. Her body will absorb the foreign mamono mana while it is absorbing her husband's essence. (source: Kenkou's 2015 Ask.fm page).
This resistance, however, weakens if her horn is broken, making her more vulnerable to becoming a bicorn until the horn regrows. (source: Kenkou's 2015 Ask.fm page).
In many Order nations unicorns are seen as harmless. If they are viewed as being "harmless mamono" then they will still not be allowed to marry. However, some countries see them as sacred beasts instead of monster girls, and in these places marriage to them is outright welcomed. (source: Patreon Q and A)
Ushi-oni
The eye patch she wears is a seal to keep her fierce libido in check (source: Kenkou’s Japanese Q and A).
Ushi-oni and other large arachne are fine with their mates riding on their backs for transport, but the activity will inspire them to do related things at night sexually. (source: Kenkou’s Japanese Q and A).
Ushi-oni silk is thick and rope-like, they aren't good at spinning finer threads. (source: Kenkou's 2015 Ask.fm page).

Valkyrie
Some valkyries do join up with female heroes. If such a valkyrie becomes monsterized she will raise the hero into a splendid mamono realm hero inma and equally splendid wife (source: Kenkou’s Japanese Q and A). Perentie note: As the term used is the general sex demon name "inma" she may become something other than the specific race "succubus."
Vampire
The vampire’s cloak is in fact her wings. She can expand or contract them at will, make them change shape into regular succubus wings to fly, or make them vanish completely if she wants but she normally keeps them in the shape seen in the profile (source: Kenkou Q and A topic).
These are among the races known to have in rare cases overcome their human-killing instincts and fallen in love with humans in the age of the former mamono lords. (source: Kenkou’s Japanese Q and A).
Vampire clans and customs
Vamp Mosquito
The transparent red organs between the breasts and on the abdomen function as blood storage organs (the blood is mixed with mana and stored), albeit the amount of blood seen in the profile image is not sucked all at once but gathered up over time (source: Kenkou tweet).
Vamp mosquitos can get pregnant more easily than most monsters, but they don't lay nearly as many eggs as real mosquitos (source: Kenkou tweet).
If a vamp mosquito sucked blood from a human woman she would be monsterized and also likely catch a mamono realm disease, however vamp mosquitos ecologically suck blood only from men (source: Kenkou tweet).

Vampire clans and customs
Spoiler
Vampire culture is divided among different clans, each with its own distinct progenitor. Customs regarding courtship and marriage can vary widely between them. Some clans believe that as nobles they must maintain decorum, and will engage in indirect blood drinking and subtle courtship rituals (for instance they may give a man a cup and he will bring the cup to a party she is attending as a signal he has agreed to have his blood sucked by her). Others have a more beast-like approach, dragging a man they want into a bedroom or biting him as soon as they feel the urge, believing this impulsive behavior is the true etiquette of nobility.
Vampires may hold parties where they invite different clans to socialize. Of course, the main purpose of such events will be to show off and boast about a new servant who will eventually become their husband.
While the methods differ, they all serve to demonstrate noble pride. The "ideal aristocrats" uphold traditional values, while decadent ones see simply being able to indulge in life with their spouse as being a true display of affluence and power. Vampires that embrace their monstrous nature will readily show off their raw physical strength, while those that focus on magic will view scholarly pursuits as a noble pastime, and those rooted in a city may deeply believe in noblesse oblige, that nobility exists for the sake of its subjects.

Wendigo
How the cloak looks varies depending on the individual. If a wendigo husband has a harem then the cloak will become larger to hold them all inside it. The form their cloak takes may also be influenced by the spirituality of the husband. (source: Patreon Q and A).
All the abyssal monsters have light-emitting organs to add to their mysterious appearance. The wendigo's are on her horns. However, while it is harder to see, she also has glowing chains (that also look like tentacles) wrapped around her wrists and ankles. While she is often supported by her husbands hands and genitals, if he were to let go she would be able to continue being held up by these mysteriously shining chains. (source: Enty info article for the making of the wendigo profile).
Regarding what the monstrous form of the husband looks like under the hood, he is described as having fluffy white fur (like the wendigo's) with the bare parts of his skin being dark in color, looking something like an abominable snowman with creepy eyes and skull ornaments. The idea is that he and the wendigo look similar enough to be male and female of the same species. (source: Enty info article for the making of the wendigo profile).
Werebat
Werecat
Wererabbit
Weresheep
The weresheep's tights are indeed clothing. As for how they work, perhaps due to the magic of her wool or magic in the tights themselves the wool pops right out over them when she wears them. (source: Personal communication with Kenkou).
Werewolf
Werewolves are effected by the full moon in various ways. In general they simply become more beautiful and vicious, but possible changes include changes in body and breast size, glowing eyes, change in eye color, hair growing longer and/or covering more of the body.
Wight
The wight's hands are covered in a body of spiritual energy made by her magic (source: Kenkou’s Japanese Q and A).
Witch
Wonderworm
What looks like clothes are actually part of a wonderworm's body (hence them having the same texture and colors). They are plump to the touch (source: Patreon reply)

Studying magic is not necessary for youko/inari tails to increase, as the tail number simply grows with the amount of mana they have. Boosts from just sex is enough to eventually reach nine tails. (source: Patreon reply).

Hot springs won't harm them, but they will make their minds feel soggy and their bodies hot. Sex will inevitably result if someone they want is there (source: Kenkou’s Japanese Q and A).

Zombie
Zombies that receive enough mana from their husbands can potentially "evolve" into wights (source: Wight profile).
It is a trait of undead in general that by accumulating power they can transform into higher ranked types of undead. However, only the zombie race can become wights. Other types of undead become their own specific higher-ranked species. (source: Patreon Q and A).
Zombie Dragon
* I would like a zombie dragon to wrap her tail around me… Monster girls from the dragon family must hold the man they have accepted as their husband as close to them as possible and be as close to him as possible. They seem to have a habit of unconsciously wrapping their tail around their husband and pulling him closer. It is a common occurrence when they wrap their body like a pretzel around their treasure-man in their sleep.
*Zombie Dragon unconsciously pulled her husband towards her with her tail*
*-choose a combination of the following-*
→ "Husband dives into her chest and burrows into her pliable body."
→ "Husband wants to have a good time and thanks her, he rapes the zombie dragon♥ Yay♥."
→\An extremely emotional stream of corruption breath, turning into a deep kiss and reverse rape/ (source: quote of KC tweet).
