### Monster Girl Encyclopedia II | The Ethereal Land of Zipangu | Kejourou

**Family**: Succubus
**Type**: Majin
**Habitat**: Zipangu Region
**Disposition**: Lustful, devoted
**Diet**: Men's Essence

Monsters peculiar to Zipangu that clad themselves in a voluptuous atmosphere that stands out. They have an appearance close to that of humans, but they have long, beautiful hair with an alluring charm that is inhuman. Many of them slip into human settlements and live there. Aside from appearing before men they like, they also sometimes blend in among human prostitutes.

Their hair is full of sex appeal and magical energy, and it has the power to bewilder men. Their alluringly fluttering hair captivates the eyes, and the fragrance that softly floats from there tickles the nostrils, charming them. Their hair is alluring to men, who will unwittingly experience desire and arousal.

They can freely manipulate this hair, and they can make it coiled around and cover a man's entire body. If bundled, their hair feels like silk of the highest grade, and being caressed by it causes an attack of pleasure that seems to coil around the male body. If they seize the penis with their hair, it's unbearable, and it'll spurt out semen, and end up sullying the beautiful hair.

Their hair is also their essence absorption organ and by sipping essence after men ejaculate in it, its alluring charm increases even more, and becomes even more beautifully fascinating. As it grows more and more attractive, men become so enthralled by it that we can even say it becomes the primary focus of their affection. They'll start to run their fingers through the hair and stroke it whenever they are free to do so, and ultimately they'll want to put their face in the hair and sniff its fragrance all day long.

Their hair can experience sense such as taste and touch for the sake of enjoying sex with men. When they feel their beloved man touching their hair and putting his face in it, they experience ecstasy, and if semen is released into their hair, the delicious taste of semen staining each and every hair is followed by a dream-like rapture, and a sensation as if they're being dominated by the man's semen.

Also, if their hair coils around the entire body, enveloping it completely, a feeling of relief and ecstasy engulfs the man, as if his entire body is gently being embraced. If one has sex in this state and ejaculates inside of them, one can obtain pleasure far beyond that of a normal ejaculation. And the pleasure grows more potent in proportion to the degree a man is fixated on their hair.

They have a custom of cutting a lock of their hair off and handing it over as proof of fidelity to the partner they recognize as their husband. Even though the cut hair is only a small part, it has enough power to bewilder men, and desire of those who accept it will swell day by day. Eventually, the man will end up visiting the owner of the hair to have his way with her.

Even if they hadn't directly accepted hair from them, men sometimes will find the cut hair coiling around them before they even realize it. Then if a man sees them for the first time, he'll never be able to run from their love, which coils around and won't let him go, just like their hair.


### Monster Girl Encyclopedia II | The Ethereal Land of Zipangu | Ao-Oni

**Family**: Ogre
**Type**: Demihuman
**Habitat**: Caves, mountainous regions, Zipangu Region
**Disposition**: Strong-willed, calm
**Diet**: Omnivorous, prefers meat and sake

The Ao-Oni is distinguished by the horns growing out of its forehead, and its namesake blue skin. It's a type of Ogre called an Oni that only inhabits the Zipangu Region. Like all oni, they have a fierce disposition and extraordinary strength. They're feared by humans as monsters, but they're actually quite intelligent and rational. They also have a calm side to themselves, which is very atypical for an oni, and for that reason, unlike others of their kind, they don't randomly assault human men. They can often be seen hanging around other oni such as the Aka-Oni, and because of their disposition, they often serve as the brain of the group, controlling the rest and restraining their emotional and coercive actions.

![Ao-Oni in such a lewd state of drunkenness enjoy passing wine and essence mouth to mouth in order to more fully enjoy their flavor.](https://mgewiki.moe/images/8/87/BlueOniExtraArt.jpg)

As previously mentioned, even if Ao-Oni find men who strike their fancy, they won't try to rape them randomly, but that's only true when they're sober. Just like the Aka-Oni, sake is their favorite thing, and if there's a guy they like, they'll probably aggressively invite him to go drinking. However, they aren't able to handle their liquor at all, rather they get dead drunk just from drinking a lot of sake, and once they get drunk off sake, rationality and self-control get thrown out the window. Their faces turn bright red, and upon revealing the lewd, drunken side of themselves, they become so lustful and ferocious that even the Aka-Oni pales in comparison. Their true nature as monsters is revealed through sake, and traces of their ordinary, intellectual personality can no longer be seen. They completely transform into lecherous perverts who seek pleasure and essence, thinking about nothing but sex with human men. Naturally, whenever they're drinking, if there's a human man nearby, they'll assault and rape him right away, so that they can enjoy the taste of essence along with their sake. And what's even more troubling, in spite of the fact that they get drunk easily, they still have a high level of maximum alcohol tolerance, appropriate for an Oni.

Ao-Oni can drink sake infinitely, becoming infinitely drunk, and grow infinitely lustful, and the feast of flesh tinged with sake, pleasure, and essence will continue until either the sake runs out, or the man passes out. Once they sober up, they go back to their intellectual state, but being monsters, if they like the guy, and deem him most worthy as both a husband and a sake snack, then they'll never let him go. Then the man will end up having to party, get drunk, and copulate profusely with her every night.

Additionally, they have a much stronger sense of shame compared with other Oni, and it easily comes to the surface. Because of this, whenever they recollect what they did while they were drunk, or even just listen to an obscene or sexual story, they become so embarrassed that their faces turn bright red, like that of an Aka-Oni.


### Monster Girl Encyclopedia II | The Ethereal Land of Zipangu | Ushi-Oni

**Family**: Arachne
**Type**: Bug
**Habitat**: Zipangu Region(Mountainous regions, caves)
**Disposition**: Ferocious, lustful
**Diet**: Carnivorous, wild animals, etc., men's Essence

A kind of arachne that only inhabits the Zipangu Region. They possess the upper body of a woman with green skin, and the lower body of a spider covered in black hair. They're one of the monsters feared as ''monstrosities'' in Zipangu. Even among monsters, their nature is especially ferocious. Tainted with immense desire, thoughts of savagely raping and violating men are always on their mind. So great is their lust that their body is always hotly seething.

Normally they live deep in the mountains, but sometimes ushi-oni come down from the mountains and attack human settlements seeking men. At that time, if they find a man who strikes their fancy, they'll shoot out webbing that is almost like a rope, tie him up, and take him back home deep in the mountains. Then, as if to unleash all the bestial lust that had built up until then, they'll rape the man and indulge in essence. No matter how much sex they have, their boundless sexual lust is never satisfied. They never get tired in the middle of sex, and they will keep thrusting their hips against a man relentlessly.

Once they've gotten a hold of a man, they never show themselves around humans again, secluding themselves in their nests deep in the mountains. They end up spending most of the day doing nothing but violating their beloved man.

Their blood is thick with mamono mana. Sometimes humans appear who try to slay these ''monstrosities,'' but those who cut them are always bathed in their blood as a result. Those who have been bathed in this blood are twisted by the high concentration of mamono mana. If it is a human man, then he'll soon change into an incubus whose mind is all but consumed with screwing monsters. If it's a human woman, then she'll end up becoming an ''ushi-oni'' herself.

When a woman transforms into an ushi-oni, the great transformation is not only external, but internal. No matter how docile her former personality was, it will change into an extremely aggressive personality like that of the ushi-oni. The bestial desire to rape men and corrupt them with their own hands boils up. The bestial lust causes her body to begin to hotly seethe as though boiling, and she becomes unable to think about anything but raping men. And then, guided by bestial lust as a new ''monstrosity,'' she'll head for a human settlement to get a man.

Additionally, the resilient body of an ushi-oni soon regenerates after being wounded. On top of that, they don't even appear to feel any pain from minor wounds. They aren't at all disturbed by the intruders who go after them. It is even said that they ignore the intruder before and after they're cut, continuing to violate their man.

- Her name literally means ''cow demon'' in Japanese.


### Monster Girl Encyclopedia II | The Ethereal Land of Zipangu | Oomukade

**Family**: Centipede
**Type**: Bug
**Habitat**: Zipangu Region (woods, mountainous regions, caves)
**Disposition**: Gloomy, ferocious
**Diet**: Meat, wild animals, etc.

A monster having the lower body of a centipede that mainly inhabits the Zipangu Region. The upper body has the form of an alluring beauty that gives off a dark impression. Just as it appears, they have a melancholy, depressive disposition. However, they also have a ferocious nature at the same time, and when they spot a human man, they aggressively assault and attempt rape.

In Zipangu, they are one of the races regarded as ''kaibutsu.'' They prefer dark, wet places, and they normally live in shadowy woods, deep in the mountains, caves, etc., but sometimes they reveal themselves before humans when seeking a man as a breeding partner.

They have extremely potent poison within their bodies. When they spot a human man, they use the mouth of their upper body, along with the maxillipeds around their necks and at the tip of their tail to bite and inject poison into a man's body. Men injected with this poison experience a rush of pleasure around the place where they were bitten at that very moment, and their bodies lose all strength. In fact, the poison is so potent that even if they don't do anything for a while, the man will continually experience an intoxicating pleasure at the place where he was bitten. After poisoning a man in this way, they will coil their long body around the man, embrace him tightly, and bind him with their countless number of legs. Just like their disposition, they violate a man with melancholic copulation.

The potent poison and ferocious disposition isn't all that's terrifying about the oomukade. They're obsessively clingy and affectionate towards their prey to the point that it borders on paranoia. Once they get a man, they're never ever willing to be apart from him. Until he becomes entirely theirs, they continue to copulate a countless number of times, continuously spoiling the man's body and heart with love and pleasure.

Though they are dangerous monsters as such, they have a huge weakness to ''human men's saliva.'' They have high resistance to their own poison, and are normally unaffected by it. However, when this poison combines with a man's saliva, a magical transformation occurs, resulting in another poison that they have no resistance to. If a man's saliva enters their body through their mouth or vagina, etc., the altered poison violates their body from within, and for a while, their entire bodies will end up being continuously attacked by overwhelming pleasure.

In spite of possessing such a weakness, love and the sweet taste of essence overwhelm them, and they kiss men against their better judgment, so they are likely to end up ingesting saliva on their own. Additionally, what appears like a pattern on their upper body is actually poison glands. It is said that powerful pleasure courses through their body if they have these poison glands licked by a man, though it's not as potent as when they take in saliva directly.

- This monster is based off of the giant centipede from the Japanese fairy tale *My Lord Bag of Rice*.
- 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.
- Oomukade are feared monster girls. They often live years in solitude, which makes them more aggressive than other species.
- During sex, they may nibble the man's body here and there, continuously injecting their pleasure-inducing venom.


### Monster Girl Encyclopedia II | The Ethereal Land of Zipangu | Nureonago

**Family**: Slime
**Type**: Semiliquid
**Habitat**: Plains, grasslands, Zipangu Region
**Disposition**: Simple, meek, devoted
**Diet**: Men's semen, sweat, saliva, etc.

A kind of slime that only inhabits the Zipangu Region. In the same way as other slime family monsters, they have flexible bodies and can change into various forms. Out of all the slime monsters, they are especially proficient in mimicry. They can form clothes that look and feel almost like the real thing. They usually go with a kimono, but they can make any clothing as long as they've seen it before. They use this ability to try to pass themselves off as human women, but since the clothing they make is always wet, it's normally easy to see through it.

![Though the bodies of nureonago are always damp, they do have the power to control the moisture they release into the environment and hold it within themselves. Thus, they are capable of both cooking and doing laundry.](https://mgewiki.moe/images/c/cd/NureonagoExtraArt.jpg)

For that reason, it is said that they only show themselves in front of humans on rainy days. They appear near human settlements, highways, etc., standing dimly in the rain, gently smiling at men who pass nearby. If, thinking that they're human women, the man returns the smile and calls out to them, then they end up recognizing the man as their husband and chase after him for the rest of his life. If the man attempts to flee, then they'll sense the presence of his essence and follow him no matter where he goes, so it's impossible to successfully escape them. Eventually, they'll even turn up at a man's home. Once she arrives at the man's home, she'll just start living there and behaving like his wife. Then she'll cover him with her damp, wet, liquid body, having sticky sex, and milk his semen.

Perhaps because they've evolved and adapted in the Zipangu environment, which has comparatively many docile and devoted monsters, even though they are slimes which fundamentally have low intelligence, the knowledge and techniques necessary to perform household chores as a man's wife is imprinted in their instinct. In this way they can skillfully and briskly take care of their husbands.

Also, they start to make their clothes according to their husband's desires. During semen milking they appear different from basic slimes which mate with hunger and lust. Somehow, it seems that there is devotion and service. In the same way as other members of the slime family, the number of individuals is increased through division. In the case of an ordinary slime, having just been born, the little slime's head would be full of thoughts of hungrily gorging on semen, but as for the nureonago, it is said that even after just being born they'll help their mother with the housework, having devoted behavior.

- When slimes can give birth to incubi, they will grow at the slime's belly. It becomes temporarily opaque and hardens around it.
- The temperature required to freezes or evaporates slime mamono would be fatal to humans as well. Heat in environment such as volcanic or desert region would only weaken them, but as long as they are well nourished by their husbands, they can live there.
- The whole body of a slime mamono is an erogenous zone, and it is also possible to concentrate sexual sensation on a part of the body at the will of the slime. Basically, when a slime is inserted into, it tries to obtain pleasure by concentrating its sexual sensation on that part of the body.


### Monster Girl Encyclopedia II | The Ethereal Land of Zipangu | Chochin-Obake

**Family**: Tsukumogami
**Type**: Magic Material
**Habitat**: Zipangu Region
**Disposition**: Devoted, calm
**Diet**: Men's Essence

The Chochin-Obake are a type of monster, also known as ''tsukumogami'' (artificial spirits), that are items used by humans which sprung to life and started moving around. They are born from the fusion of mamono mana and either the feelings of gratitude that dwell in an item which was treated with care and used for a long time or the negative feelings of an item that was treated carelessly and thrown away. As their name suggests (Chochin-Obake literally means ''paper lantern monster''), they are a tsukumogami that is a living paper lantern. Flames that light everything around them burn within their bodies. Since they were originally a tool, they desire to be used by human men more than anything.

Of course, they can still be used to illuminate the darkness, which was their original purpose. More than that, however, what gives them the greatest pleasure is having men freely use their female body which they obtained upon becoming monsters. Another thing, their flames are fueled by the essence of human men, so in any case, they need to have sex with a man.

Chochin-Obake that are born from negative feelings have an extremely monstrous nature. They appear together with a faint light before men walking the roads at night without a light. Since they're so obsessed with being used, in order to make a man use them, they'll attack and try to rape him. Once they've had sex with the man, they'll recognize that man as being their owner, and return to his home as his property. Then, night after night, they'll rape the man, and have him use them, illuminating the darkness of the night with their flames.

Additionally, there are also those who visit the man who treated them carelessly and keep raping the hell out of him again and again until he decides to use them of his own free will in order to instill the man with the knowledge of the goodness of their body. On the other hand, the Chochin-Obake that are born from the feelings of gratitude go all out in displaying their devotion as a tool, and serve their owner. To them, to keep being used by a man forever is their greatest joy. Night after night, they beg the man to use them, and make him a prisoner of their body.

The flame inside their body is normally small and faint. In proportion to this, their disposition grows more docile, and the sex also becomes more gentle. However, during sex, as essence, which serves as fuel, is poured inside their bodies, their flames grow more intense and increase in brightness. The more this happens, the more aroused they become, and the kind of lust one expects from a monster becomes conspicuous. They start moving their hips aggressively, and the sex becomes more passionate. Also, men who are joined with them have their lower abdomen directly illuminated by their flames, causing it to become extremely hot, and their penis swells up bigger inside them. Naturally, they keep thrusting hard and release large amounts of essence until dawn, continuously raising their flames and desire to become even bigger and brighter.

- This monster girl is based on a tsukumogami in Japanese folklore.


### Monster Girl Encyclopedia II | The Ethereal Land of Zipangu | Karakasa-Obake

**Family**: Tsukumogami
**Type**: Magic Material
**Habitat**: Zipangu Region
**Disposition**: Devoted, lonesome
**Diet**: Men's Essence

The Karakasa-Obake are a race with the form of a large umbrella that were once tools used by humans. They became monsters after gaining life and sentience from absorbing enough mamono mana over time. The Karakasa-Obake are also referred to as ''tsukumogami;'' a type of monster that used to be tools, but gained a life of their own. They have a strong desire to be ''used'' by the human males who own them regardless of how they were treated, Those who were handled with care, or were used crudely and thrown away, have an equal chance of becoming ''tsukumogami'' and seek to be with their owner.

As their original form and purpose was mainly for use on rainy days, the strong desire to serve their owners changed their bodies into that of beautiful young women so they may be more useful in many different situations. They believe that every part of their bodies is to be used in service of their owner as pleasing them is the greatest joy that they can receive. Even if the stimulation they receive is only slight, to the Karakasa-Obake it is magnified greatly, often surprising their owner at the responses they give in return.

![The karakasa-obake's canopy is capable of floating without support, forming a roof to cover the couple's relations, making a place for just the two of them.](https://mgewiki.moe/images/2/2b/Karakasa-ObakeExtraArt.jpg)

Beneath their umbrella canopy there's an organ similar to a giant tongue which they will often use when they think of servicing their owner, using it to seize and draw him close. A lubricating fluid that increases the responses to stimulation is secreted from the tongue. By licking their owner and their own body, they generate even deeper pleasure further pleasing themselves and their owner. Once the Karakasa-Obake closes her umbrella it will repel not just rain, but even swords and magic, creating a world just for her and her owner that bars all intrusion.

In that confined space with two bodies glued together, the only thing one would be able to see is the alluring body of the Karakasa-Obake and the only thing one could do in response is give in to desire and use them. From repeatedly using them the owner would become a prisoner of the pleasure they can bring, just as the Karakasa-Obake desires. The owner will then end up being in the same umbrella with them repeatedly, continuously using them relentlessly. To the Karakasa-Obake and their owners, every day will become full of happiness and ecstasy. A routine that will become difficult to change. Although they no longer have any relation to the weather, their bodies still recognize rainy days as "days when they can be used" causing them to strongly throb with desire.

Those who become tsukumogami after being handled with care repay their owners' kindness with more than sexual favours: they often devotedly provide other services by taking care of his daily needs. The Karakasa-Obake who were treated poorly have the same devoted personality but attack men more frequently, out of fear of being neglected, often attacking their owner with such frequency that it becomes a pathological psychosis.

They easily get lonely when they feel that their owner is not using them often enough and will seek and capture them within their umbrella, locking them both in a world of their own.

- This monster girl is based on a yōkai karakasa-obake (also known as Kasa-obake).


### Monster Girl Encyclopedia II | The Ethereal Land of Zipangu | Ittan-momen

**Family**: Ittan-momen
**Type**: Magic Material
**Habitat**: Zipangu Region (Human settlements and highways)
**Disposition**: Whimsical, poor at expressing emotion
**Diet**: Human men's Essence

A bizarre monster inhabiting the Zipangu Region that has a cotton-like body. They mainly appear at dusk, fluttering in the sky. It's very difficult to tell what they're thinking: they may attack when they spot human men, they may just fly around in the sky, and sometimes they space out when they get stuck on something.

When they fly up to a man on a whim, they will bind him by wrapping around him with their cloth body and attempt to have intercourse. At a glance, it looks like they only have a body of thin cloth, but as soon as their cloth coils around and clings to something; it makes the outline of an alluring woman's body emerge on the other side. Nothing should exist on the other side, but it certainly does feel as though a woman's body really exists from the feeling one gets as one's fingers sink in when touching over the cloth. In fact, it's all just the use of mamono mana and the cloth body to recreate the resilience, feeling, and weight of a woman's body. They skillfully produce a body by winding their own cloth with their mamono mana.

![Though the ittan-momen's body is made of cloth, the texture of her lower body is unmistakably a woman's as she engulfs the man's sex.](https://mgewiki.moe/images/c/c1/Ittan-momenExtraArt.jpg)

For that reason, sensory organs and so on are on their cloth part, which is their original body. Unlike an ordinary woman's body, the cloth body doesn't have different functions and sensitivity in each part. As for the woman's body created by winding cloth, the vagina, mouth, breasts, and buttocks are of course semen milking organs and erogenous zones for pleasuring and making love with men, but so is the rest of it, including even the face, hair, armpits, belly button, etc. The cloth has such an exquisite feel to it that men who are their husbands unanimously claim that they spontaneously get the urge to rub cheeks with them, and it really shows its stuff when it comes to fondling men. If the body is rubbed, unlike other cloth and human skin, while it is still soft and smooth, there is also a feeling like occasionally getting stuck that produces stimulation which induces pleasure in a man's body.

If one inserts his penis in the area formed by triangular creases which corresponds with the vagina of an ordinary woman's body, even though it's over the cloth, there's a feeling of heat and wetness as the penis plunges inside as if it were real. When taking in a penis, the cloth changes shape to match it, and when they rock their hips, at the same time, the cloth enveloping the penis can freely stroke it. This results in a two-fold pleasure that's like being milked by a vagina and caressed at the same time, which causes most men to ejaculate at once, staining their cloth with cloudy white semen.

Since it's made of cloth, a man's semen will easily soak into their body, and any spot on the cloth, any spot on their body, can absorb semen with extremely high efficiency. For that reason, even though they may look silly when wrapping their cloth body around their husband and sleeping happily, or swaying with just a bit of their cloth fastened to their husband, they do possess high magical power from having sex with their husband again and again, and despite appearances, no small number of them are great yokai.

When monsters obtained their current female bodies, the ittan-momen ended up with a half-baked body made of cloth, but it seems they themselves are actually very pleased with their form. What they say is that since their thin cloth body can easily soak up semen, they can easily have their husband's semen permeate through their entire body, literally staining themselves completely with their husband so they can immerse themselves in happy feelings all the time.

- An Ittan-momen's cloth body take up little volume, which makes it easier for their husband to completely dye them with his essence. It's related to the Sabbath theory that the smaller your body is compared to him, the more space your onii-chan occupies in it.


### Monster Girl Encyclopedia II | The Ethereal Land of Zipangu | Ochimusha

**Family**: Zombie
**Type**: Undead
**Habitat**: Zipangu Region (Graveyards, former battlefields)
**Disposition**: Calm, devoted
**Diet**: Men's Essence

Warriors of Zipangu called ''bushi'' who died with regrets but were revived by yokai energy dwelling in their corpses. While they are undead, a firm will dwells within their eyes. Some of them return to the place they used to live to once again serve their former lord, and others will wander on foot seeking a new lord, becoming the faithful servants of the human men they encounter.

They have a peculiar value system called ''bushido'' which deems selfless devotion and taking responsibility by risking one's life as virtuous, and they will personally support their lord along his path and protect him. Even after death, they never neglect their training, and continuously boost their power as swordsmen. The sharp swords bushi wield that are called ''katanas'' become magical swords (lit: youtou) in which yokai energy dwells when gripped by them, releasing a flash of mysteriously alluring light, and their swordsmanship becomes even greater than when they were living.

Originally, they did battle with a readiness to lay down their lives, but having already lost their lives once and become undead, they are undying soldiers who do not lose their lives on the battlefield. No matter how much their bodies are wounded, their wounds will heal by receiving their lord's affection, and they will regenerate an even more beautifully powerful body.

They have high intellect, endeavoring in both the military and literary arts, and appear calm and collected, so they don't give off an undead vibe at all, however, by becoming undead, as a monster, their feelings of respect and obedience towards their lord become mixed up and merge with feelings of love and passion towards a man. Their loyalty towards their lord is at the same time the wholehearted romantic sentiment of a woman towards a man.

They desire to serve their lord, not only as a warrior, but as a woman as well, and should their lord desire them, they're always ready to offer their whole body at any time. But having lived and died by the sword, despite being monsters, they are not very skilled when it comes to romantic affairs, and because they tend to think of it as impertinent, they will not make a move on their lord themselves. However, it is said that they will seek their lord's affection after having fought and risked their life for him.

From all of their speech and conduct while serving constantly at their lord's side, one can catch a glimpse of their love and loyalty towards their lord, so naturally, it's not uncommon for a lord captivated by that to end up in a physical relationship with them. And then, when they offer themselves to their lord as women as well, their hearts experience supreme bliss. Perhaps due to their nature and the monster's instinct, each time they have sex, it's as if the woman part of them gets tempered. While retaining the looks of their beautiful and well-toned warrior body, day by day, they change on the inside, becoming able to please a man like a veteran prostitute, and their body also changes, growing lewder and more womanly, as is appropriate for milking semen.

Furthermore, they are very obsessed with producing an heir for their lord. They won't openly assert their opinion, but they desire to bear their lord an heir themselves if possible. In Zipangu, as of the present, fundamentally only sons can succeed the house. Due to the circumstances of the present world, they can only bear daughters, so sometimes they fight under powerful yokai who have a radical ideology, and expand the territory of the yokai by slaying people one after another with their magical swords, which convert those slain into yokai.

- When they rise as undead, the regular sword of an Ochimusha becomes a mamono realm silver weapon.
- 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.
- 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.
- 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.


### Monster Girl Encyclopedia II | The Ethereal Land of Zipangu | Unagi Joro

**Family**: Mermaid
**Type**: Mermaid
**Habitat**: Zipangu Region (Near large ponds, lakes, and rivers, etc.)
**Disposition**: Calm, devoted, lustful
**Diet**: Carnivorous: seafood, etc.

A type of mermaid living in the Zipangu region. They have the body of a long slender fish covered in a mucus membrane. The slimy mucus secreted from their body contains many compounds that restore vitality and stamina, and since they themselves have it inside their own body, their body is also full of an unmanageable amount of stamina and lust.

Normally, their lascivious true nature is masked by a soft and gentle demeanor, and a devoted appearance befitting of a race of Zipangu, but their unconcealable charm oozes out from bits of their speech, the way their body wriggles whenever they move, and their posture. They don't directly seduce men, but nevertheless, because of their appearance, they're good at getting men in the mood, and in most cases, men will be eager to seize their heart.

![In this state, it is too late to retreat, for the more one moves, the deeper one will sink into the unagi-joro's soft body, beckoned inexorably into her flesh.](https://mgewiki.moe/images/b/bf/UnagiJoroExtraArt.jpg)

Their body is covered in a mucus membrane to protect them from desiccation. When wrapped in this slippery body, even if one tries to grab their body and pull them off, one can't get a good grip. They can adjust the state of the sliminess of the mucus membrane at will, and without the slime, it makes it easier to grab them. On the other hand, they can also make those who touch them slip to the degree that they want. The hands of men that try to touch them slip in the slime, with the extra momentum causing them to touch their breasts or genital area. When a man panics and twists his body in an attempt to get away, he'll slip even more, pressing against and knocking down their soft body.

By the time he becomes aware of it, not only will her body be coiled around him, the man's four limbs will also be wrapped around the girl. Even if it should just be a casual touch, one will end up entangled and locked in a grapple with them.

In this way, they don't just seize a man's heart, they seize his body using their mucus and create a situation where he can and will make a move on them. Before they know it, men who strike their fancy will find their body and heart seized in this manner and gradually end up having sex with them.

Their soft body has just the right resilience, and being covered in it feels pleasant. It's as if a man's penis will melt when having sex wrapped in their body. During sex, a man is made to drink mucus transferred mouth-to-mouth, and mucus coils around his penis with wet sticky noises, continuously restoring his vitality and stamina. No matter how much they have sex, they never get exhausted, and the more they have sex, the more his stamina increases. A man will come to desire to keep having longer and more intense sex with them.

Those who have a husband expose their lascivious true nature and desire to service their husband with their own body. Due to their devoted nature, they make good wives who pour their heart into taking care of their husband, but the home cooked meals they make every day always have their mucus mixed in. It's highly nutritious with a rich flavor which will appeal to their husband's tastes, and continuing to eat the food every day will build up his stamina to the point that he will always have an excessive amount of vitality and stamina, and when their husband wants sex at every opportunity, they will gleefully accept it.

Since he can get energy from having sex with them, even if the husband does have a job, he'll develop a habit of having sex with them until they're stained cloudy white after eating breakfast, before heading off to work.

- Regarding the unagi-joro's clothes, Kenkou Cross 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.


### Monster Girl Encyclopedia II | The Exotic Hospitality of Ryugujo | Umi Osho

**Family**: Turtle
**Type**: Aquatic
**Habitat**: Zipangu region (sea)
**Disposition**: Timid, devoted
**Diet**: Omnivorous: seaweed and crustaceans, etc.

A monster with a large turtle shell on its back that inhabits the seas of Zipangu. Having meek and timid personalities; not only do they not attack humans, it is said that sometimes they are so astonished when they come across a human that they hide in their shells, refusing to come out.

Like ''Sea Bishops,'' they are the priestesses who serve the sea god, and they can perform the ritual to remake the bodies of human men who are joined with monsters in the sea, enabling them to live in the sea. Due to this ability and their honest and simple nature, they are loved by monsters of the sea.

![The umi osho's strange power is such that, thus overturned, they inflame men's carnal passions and become inclined to tease them.](https://mgewiki.moe/images/4/45/UmiOshoExtraArt.jpg)

They themselves are quite harmless beings, but if someone were to try and harm them, he would surely be dragged under the sea by the monsters of the sea in a fit of rage, or, in some cases, by storms and billows caused by the sea god. And then, the man would end up being swarmed by monsters and violated, but the umi osho herself would disregard it as if nothing had happened, despite possibly having been harmed, and she would bless the union of the man and a monster, the birth of a new married couple, from the bottom of her heart, performing the ritual to enable him to live under the sea.

They hesitate to even speak to men in a seductive manner, let alone attack them, yet their true nature is monstrous, and they eagerly anticipate being joined with human men. Also, as a race, they have strong masochistic feelings. Longing to be pursued by a man so fiercely that it is overbearing and violent, to receive his raging lust in their body, for these things they pray to the sea god day after day. Perhaps due to a blessing resulting from their fervent prayer and their original cultivation, their ordinary speech and behavior irresistibly provokes sadistic feelings in men.

Perhaps because they mostly have petite bodies in general and carry disproportionately large and heavy shells, should they fall over for some reason, they aren't quite able to get back up. It is said that when seen in this manner, they experience agonizing shame, and they look so pitifully adorable and defenseless that it easily makes a man's sadistic feelings run wild: a man would take advantage of their inability to resist and violate them according to his desire.

Even when being violated, they retain their modest attitude, and rather than indulging in pleasure, it's more like they devotedly offer themselves to a man to quell his rage in a manner befitting of an adherent of the sea god. However, their true nature as a monster can be briefly glimpsed from the way they move their hips, and when taking a meat rod, they clamp down firmly, greedily refusing to let go, spurring a man to push deeper and deeper inside. Their mouth is just as greedy as their lower parts, and it is said that once they take a penis inside, they'll keep sucking without letting go until he's all out of semen. Also, it seems that they will experience great joy and ecstasy on this occasion if a man puts his hands on their head and presses it down, and then fellatio will become much more lewd and alluring, or something like that.

Additionally, they're guides to ''Ryugujo,'' which also serve as the sea god's shrine, and they have been granted the power to enable even men who aren't married to sea monsters to temporarily breathe under the sea. Ryugujo exists at the bottom of the sea, and it's a place described as one of this world's paradises, where guests can expect dream-like hospitality. Of course, men that strike their fancy will be invited, but other human men are also invited according to requests by the monsters of the sea.

- 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.
- The umi-osho's sleeves and socks are themed after turtle fins and scales (this implies her hands and feet look normal underneath).


### Monster Girl Encyclopedia II | The Exotic Hospitality of Ryugujo | Otohime

**Family**: Dragon
**Type**: Mermaid
**Habitat**: Zipangu Region (sea)
**Disposition**: Selfish, cheerful, devoted
**Diet**: Carnivorous: Fish and shellfish, etc.

Monster princesses that rule over ''Ryugujo'' which exist at the bottom of the sea in the Zipangu region. They are treated as mermaids, but they're actually a kind of powerful dragon that possesses the power to manipulate sea currents and cause tsunamis. Depending on the area, they are worshiped as gods of the ocean. They are selfish and overbearing, but also have tolerant and easy-going personalities.

Since they present themselves towards anyone in a familiar and playful manner, they are adored by their monster underlings. Having pleasure-seeking personalities, they like to enjoy themselves every day above all else. Other than that, they also enjoy entertaining others. ''Ryugujo'' have become places where those who live there can enjoy themselves without getting bored and have also been opened to the outside as amusement cities. Sometimes, they send messengers to the surface to invite humans.

In ''ryugujo,'' guests are always welcome and drinking parties unfold day and night. Many monsters entertain guests, dancing beautifully, then bringing the fascinated men into their bedrooms. The otohime, who are at the center of these banquets, are outstanding dancers themselves. The sight of them dancing is so beautiful that it momentarily dazzles those who watch, making them forget the passing of time. Through dancing, the ostentatious exhibition of their sublime, powerful draconic form, as well as their womanly form, which is so graceful and beautiful that they might well be mistaken for celestial nymphs, compels observers to recognize them as beings which ought to be revered.

However, despite this sense of mystique given off by their appearance, as a matter of fact, they merely dance to entertain themselves as well as those who watch. Also, if there is a noteworthy man among those observing their dance, they'll bring him into their bedroom, as if to say their position as princess is irrelevant.

The men they desire as partners are companions who have the greatest reactions to what they do and won't bore them, such as men who thoroughly enjoy it when they decide to entertain them by taking them around ryugujo, which they are very proud of, and men who overreact to having their body teased. On the other hand, no matter how lacking and weak a man's responses may be, as he spends time with the otohime, which have a powerful charm as female creatures, eventually every little thing they do will drive him wild with lust. Sex with them is like a service to entertain the man, and he'll have a maximum reaction by releasing mana during their lovemaking, thus changing into an ideal husband to them.

Most men who visit ryugujo will end up choosing to live with monsters as their partners, however, there are also those who are intent on returning to the surface. Such men are given souvenirs known as ''tamate-bako.'' When a man opens the box, imbued with a spell by the otohime, magical smoke spills out and envelops him, showing him an illusion in which he can relive the paradise-like days at ryugujo. Furthermore, besides just re-experiencing the same things, he is also shown all the other ways to enjoy himself at ryugujo that he didn't get to experience during his visit, and if there is a monster who was really into him, it is said that he'll experience a simulation of the pleasure of sex with that monster that he still had yet to taste.

Because of this, the disparity between daily life and the paradise-like days at ryugujo will make him feel old, and he'll then long to visit ryugujo once again. Shortly thereafter, someone from ryugujo will once again appear to welcome him.

- 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.''
- The otohime's giant dragon form looks like a combination of a seahorse and a dragon and has flashy fins.
- The ''treasure ball/jewel'' on the chest of every dragon family monster is a solidification of the dragon's mighty magic that is formed from her body. If it is removed she simply grows another one. The jewel can be used in the creation of various magical tools and armors.


### Monster Girl Encyclopedia II | The Ethereal Land of Zipangu | Nurarihyon

**Family**: Temptress
**Type**: Majin
**Habitat**: Zipangu Region (Human settlements)
**Disposition**: Lustful, spiteful
**Diet**: Omnivorous

A race of yokai that inhabit Zipangu. Often deliberately evasive during conversations just to tease people, they have unconventional personalities that are slippery and hard to grasp; and are said to set foot inside people's houses unnoticed and begin to make themselves at home as if it were their own house, sipping tea and smoking a kiseru. At a glance, this race is nearly human in appearance, but they are among the most distinguished of the great yokai of Zipangu and are said to drape their body in the darkness of night and command one hundred demons. Night is the time of the yokai, and just by being there, the nurarihyon who drape themselves in the darkness of night invigorate the yokai, creating a passionate nighttime atmosphere for married couples.

![A man finds himself incapable of wondering how the nurarihyon came to lie awaiting him in his bed. All he can do is obey her call and slip in with her.](https://mgewiki.moe/images/9/95/NurarihyonExtraArt.jpg)

After entering the home of a man she's taken a liking to, she'll treat the home owner in a relaxed, friendly manner, and even dine with him, but it's said that the occupants of the home will be unable to sense that anything is amiss, as if they were seized by the delusion that the nurarihyon herself is the mistress of the house. And, as if it were only natural, she'll also enter the man's bed; but even so, the man won't be able to feel that there's anything odd about her being there sleeping with him in his futon. On the contrary, he'll feel that it's a natural thing to be embraced by her since she is the mistress, and he'll even feel delighted to have been chosen as her partner.

As rulers of the night, they are also temptresses who possess superior seduction techniques, and just by stroking with their slender fingertips, they can provide a man with comfortable pleasure. In fact, it's said they can even cause a man to ejaculate at will with only a single fingertip. If one were to spend a night with a nurarihyon, the pleasure would be so overwhelming that even reality would then feel hollow, and ruminating on the deed would only cause him to miss them more. A man would just feel inextricably compelled to wait for the yokai to visit again the following night.

Even after that, the nurarihyon would continue to stay in the man's house, but since they joke around all the time, it's impossible to grasp their true feelings, so sometimes men may experience feelings of loneliness and anxiety when unable to tell for certain whether the nurarihyon like them. However, the words of love they whispered at night in bed don't give off the usual joking vibe at all, and they definitely convey their true feelings. For that reason, men will start to long for the arrival of the night from the bottom of their heart.

As rulers of the night, they possess an enigmatic charm that is both fascinating and majestic. Their appearance inspires yearning not only in yokai, but in humans as well. In the case of a man, he'll experience a powerful attraction to yokai and desire to become a yokai's partner. In the case of a woman, she'll end up desiring to become a yokai herself just like them.

It is also said that men who become their husbands have a charm that is so attractive to yokai that they were chosen as their partners. By copulating with them every night and coming to desire perpetual night, that charm will eventually be made to bloom, and a man will become a worthy ruler of the night who can stand alongside the nurarihyon as her equal. He'll become someone who can dominate many yokai with his body, a being worthy of serving. Many yokai will be attracted to the man and desire to spend the night with him as his concubines. Due to the nurarihyon being draped in the darkness of night, the man's surroundings will be altered into a state of perpetual night with yokai always seeking copulation. As their master, he will end up spending the never-ending night copulating with yokai one after another. It will reach the point that at any given time, the man will always have a crowd of yokai who yearn for him surrounding him, and if the man were to take a walk outside, the yokai following after him would form a huge swarm, creating a spectacle known as ''a night parade of one hundred demons.''

- 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.
- 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.
- Kenkou Cross 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).


## Monster Girl Encyclopedia III | Devil Bug

**Family**: Devil Bug
**Type**: Bug
**Habitat**: Indoors, caves
**Disposition**: Lustful
**Diet**: Anything edible

An insect monster known as ''devil bug'' that has existed since ancient times. They prefer dark, damp places, and aside from dwelling in caves and the like, they also often sneak into places such as warehouses and human dwellings unnoticed, living under the floor, in the attic etc. Their bodies are supposed to be right around the same size as a human girl, yet it's said that they're able to invade even small homes and settle down without the residents being aware of it.

While they are intelligent enough to use language, they're almost completely irrational, and their behavior is directed by instincts such as hunger and lust. What they concern themselves with is eating or having sex with a human man. They can actually sense the odor of human men and essence and their body is always burning hotly with the urge to mate. They crawl around excitedly seeking human men.

As soon as they spot a human man, their eyes become fixated on only him. Their hotly flushing body will be more than ready enough, so they'll swiftly leap at a man, attack, and attempt to copulate with him as soon as possible.

They always live in a group, and it is said that if there's one, there must be thirty in the same place. For that reason, once an individual that has captured a man begins having sex with him, they'll soon sniff out the thick odor, and then a great many devil bugs will appear, and the man will end up being surrounded and violated by all the extremely aroused bugs.

Once that happens they won't let him go until he passes out. They'll continue to use his body to console themselves meanwhile, and when he later wakes up, the devil bugs will be overjoyed, and they'll attack and copulate with him once more.

Even if there's no man in the house, just sniffing the barely lingering scent of a man is enough to put them in a state of lustful frenzy. In the case that they are unable to have sex with a man, they'll either masturbate while going around looking for a man, or go at it among themselves until they become covered in one another's love juices. Even among all the monsters, they have especially little concern for the father-daughter relationship. Once a child has grown to a certain degree, she'll no longer be able to see her father as anything other than a man. When her body gets hot for her father, she'll obey it, and attack without any regard for the fact that it's her own father.

Aside from the scent of essence, they're also attracted to the lingering odor of sweat, filth, and more, so the filthier the home environment is, the easier it is for them to settle there. If you don't want to be attacked by them, I recommend keeping your body and room clean.

- 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.
- Despite their love of filthy environments, devil bugs themselves have relatively clean bodies thanks to the protective effects of mamono mana.
- 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).


## Monster Girl Encyclopedia III | Tritonia

**Family**: Shell
**Type**: Mollusc
**Habitat**: Oceans
**Disposition**: Gentle, simple
**Diet**: Omnivorous—eats anything

They are monsters who live in the ocean and originally possessed shells, however it is supposed that they abandoned their shells through the process of evolution due to the necessity of showing off their own bodies to males. Aside from crawling along the bottom of the ocean, they can wave the part of their body that flutters to move through the water as if floating. Their bodies are so soft that when touched by another person their hands will sink into it. Likewise, they are a docile race with a soft demeanor and temperament.

Their bodies are adorned with fins, and depending on each individual and the environment in which they live, there are many different beautiful colors and a variety of patterns, which makes them appear just like a lady wearing a dress. Those who behold the elegant figure of them swaying their fins will likely be charmed. The beauty of it enthralls not only men, but women too, and even among humans, dresses that were patterned after their appearance are favored by noblewomen.

The feelers growing from their head sense the presence of men and unconsciously guide them towards them. It's said that occasionally they even come up to the surface. However, they themselves are extremely gentle monsters, and even if they do encounter a man, they just act spaced out or approach him in a calm and friendly manner, and would never aggressively attack. On the other hand, the tentacles that they have on their backs act autonomously from their will and thoughts, and upon sensing something moving behind them, they will automatically seize prey or attack an enemy. If it's a human man that's there behind them, they will aggressively capture him due to the monsters' instinct, sometimes even coiling around his body, teasing him with pleasure to the point of ejaculation, according to what some say.

They don't have any sensation in the tentacles on their back, but the feelers on their head are sensitive to men's mana, however, since they can only sense the location of a man extremely vaguely, they will just continue to search for a man who isn't in their field of vision regardless of the fact that they're actually carrying the man on their back. It is often the case that they will finally realize that a man is stuck in the tentacles on their back only after the mana has been squeezed out of him countless times by their tentacles. Thus in the situation of encountering a tritonia, hiding oneself is dangerous, and it's probably safer never to go behind them and instead inform them of your presence from the front.

They have a habit of recognizing things that have sunk into their own body as belonging to them. In the case that a man buries himself in their body, or even if they themselves, to look after him, embrace a man who was violated by their tentacles; in either case they'll recognize the man as their husband and seek to copulate. When having sex, they'll embrace a man to hold him inside their soft body and do it while gluing each others' bodies as closely together as possible. They like to have their husband's body sink inside their own more deeply. Besides just deeper pistoning, such things as deep kissing and burying one's face in their soft breasts are also likely to greatly please them.

Also, it's not just the man's body that they try to make sink inside them. If it's an unmarried individual, she basically won't refuse any man who wants her. And towards the man that became her husband, she'll show a deep tolerance as if she's willing to accept anything. When a man seeks them and begs for their affection, they experience powerful joy as if their husband's heart is sinking inside them and becoming theirs, so they will repeatedly gently embrace and have sex with their husband, continuously providing pleasure and comfort so that he will be dependent on them.

- This monster girl is named after sea slugs, also called nudibranchs, shell-less marine gastropod molluscs in the genus Tritonia.
- Tritonia come in many colors and patterns depending on the individual. The profile individual is based on Hypselodoris festiva.
- 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.


## Monster Girl Encyclopedia III | Night Gaunt

**Family**: Succubus
**Type**: Fiend
**Habitat**: Underground, caves
**Disposition**: Indifferent, obedient, malicious
**Diet**: Men's Essence

Fiends with a bizarre appearance who have their whole body covered in a black film, and one of the races of monsters belonging to the abyss. They are poor at expressing emotion, and it's difficult to read their intentions from their expression. Since they serve someone, and basically act in accordance with their master's will, it's hard to tell what they themselves are thinking, but if a human strikes their fancy, they'll soar through the sky and carry him where he wants to go. Conversely, if they don't care for a human, apparently they'll snatch him up and carry him off into the sky, only to drop him right in the middle of a swarm of monsters in heat, so it seems that they do indeed have emotions.

Normally, they lurk in dark places such as underground or in caves, but when night falls, they fly around the sky, intent on swooping down on human men who strike their fancy and wrestling them. Their behavior after that is quite eccentric. Even after binding a man, they don't go straight into attempting copulation, instead only caressing him intently. At a glance, from the way it looks as their busily moving fingertips stroke a man's body, it even seems as though they are tickling the man, but the purpose of this behavior is to coat the man's body in the mucus secreted by their own body. Mucus is thoroughly and persistently plastered all over a man from his face and chest all the way down to his lower parts, and as it permeates his body, so too does the pleasure induced by their caresses intensify. A man whose expression was filled with disgust and bewilderment at the beginning will end up grinning lewdly later on.

At this point, they finally seek to copulate with the man, and after even his mind has been violated by the mucus, he will not refuse it. In fact, sometimes, the man will end up attempting to initiate intercourse on his own. The pleasure induced by their body is painted over a man's mind along with the mucus, and once a man has known it, he won't be able to stop grinning lewdly at them and lusting insatiably for them.

Once the mucus has completely permeated a man's body through intercourse, his nature will change so that he will become a fitting husband for them. He obtains a grotesque demon-like form, and along with that, he can secrete and control mucus just as they do, plus he'll be able to dissolve the film covering their body by touching it. Additionally, their expression actually changes in a variety of ways, and their husband will then be able to sense their emotions, although it is said that they still appear emotionless to those other than their husband and fellow members of the same race. After obtaining a husband, they become dependent on their husband's lust and will, and they will mostly think and act in an obedient manner. Generally, they'll end up spending their time constantly copulating.

Based on their appearance, it is easily possible to distinguish whether or not they have a husband. Married individuals have a grotesque creature, which is their husband grappling them from behind, with countless tentacles crawling all over them, and it can even look like they're having sex in the rear entry position. Moreover, the black film covering the body of such an individual is not their own, but their husband's mucus. The film pulses, vigorously squeezing and rubbing their breasts and buttocks according to their husband's will, continually providing pleasure and ecstasy.

The husband is also freely able to return to human form, but since their husband had gained total dominion over them by constantly joining with them and continually providing pleasure, it seems they experience anxiety when he changes into human form and separates from them, and it's said they will behave in a clingy manner towards their husband.

- This monster is based on creatures that appeared in H.P. Lovecraft's Dream Cycle Novella series. The Night Guant made its first appearance in *The Dream-Quest of the Unknown Kadath*.
- In the profile illustration, the only parts of the body that are the night gaunt herself are her humanoid body and her horns. The tentacles, wings and tail are formed by her husband, and are made of the same rubbery material as the suit that covers her skin. 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.
- 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.
- 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).


## Monster Girl Encyclopedia III | High Orc

**Family**: Orc
**Type**: Beastman
**Habitat**: Mountainous areas
**Disposition**: Lustful (bold, ferocious, malicious or timid, devoted)
**Diet**: Omnivorous: eats anything

Beastmen having the characteristics of a boar, they are a higher-rank variety of ''orc.'' Despite their thickheaded appearance, they possess both superhuman strength and quick wits. Their specialty is charging and by doing so, they can easily send a crowd of people flying; even heavily-armored knights would be knocked into the air.

They are leaders who command hordes of orcs that gang up before mobilizing. As powerful, courageous champions, their mere presence is inspiring to the orcs, assuaging their fears and causing them to maximally exhibit their orcish nature to persecute the weak. Orcs under the command of a high orc become bolder and attack human men without hesitation. The high orcs themselves even exceed orcs in ferocity and belligerence; true to their own desires, they take action in pursuit of human men who will serve as their prey and aggressively attempt to violate them. They have the same devious personalities as orcs, and it is said that sometimes they even lead armies to attack human villages or bandit strongholds, etc.

A high orc's body produces a peculiar odor, and when orcs, who have a sharp sense of smell, get a whiff of it, it intoxicates them and excites their lust, transforming the pig beastmen into brave and ferocious warriors. If a high orc gives the order, the frenzied orc warriors will rush a man all at the same time, and a man captured by them is a slave for satisfying their passion and lust; in other words, he would immediately be taken back to the orcs' den as their husband, and end up having to live according to their carnal desires, covered in their soft bodies. Their den is pervaded by the choking feminine stench of the high orc, which endlessly arouses the lusts of the flesh in all the orcs and their partner, causing a relentless feast of flesh, filled with pleasure and cries of ecstasy, to unfold.

While the presence of a high orc inspires absolute confidence in orcs and makes them feel powerful, on the other hand, the defeat of a high orc causes all the orcs to become distressed and panic-stricken. It's said that even orcs who had supposedly been raging a short time ago would uniformly lose the will to fight and collapse on the floor.

Furthermore, when defeated by men, contrary to their violent and belligerent personalities, even the high orcs themselves will become self-conscious of being female and surrender their body and heart. They undergo a psychological transformation, becoming servile and subservient so that they take pleasure in being violated by the male, and their body also transforms into soft, lovely flesh that exists only for the male's pleasure; just being touched by the male will make them lose their strength and prepare to receive him, or so it is said. So too will their body odor also transform into a scent that's alluring and invigorating to the male; just smelling it will cause his penis to swell up to the point that it's ready to burst and arouse carnal desires for the high orc herself as well as the orcs. Additionally, the hearts of orcs who smell it will be filled with a sense of defeat regarding the man, causing them to transform into ''females who submit to the male.''

According to their husbands, their body odor can be quite addictive, and during sex, the men spend a while sniffing their body odor to arouse themselves and achieve a maximal erection. And then, the men enjoy violating the lovely flesh of these females who can never oppose the penis to their heart's content.

- The condom-like objects the high orc carries are made from the caps of a special mushroom (translation of name unclear but something like ''Camuli''). 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.
- The bones and skulls on the high orc's clothes and weapon specifically come from mamono realm pigs.
- 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.


## Monster Girl Encyclopedia III | Greenworm

**Family**: Worm
**Type**: Bug
**Habitat**: Plains, forest
**Disposition**: Simple, gentle
**Diet**: Herbivorous: fruits and vegetables, etc.

A caterpillar monster with a soft, squishy green body that is the larval form of the butterfly monster ''papillon.'' They are a docile race with low intelligence and move slowly, but when danger approaches, a strange smelling secretion which causes those who get a whiff to feel exhausted trickles out from the antennae on top of their head, neutralizing enemies.

This race has a form specialized for ''feeding'' to obtain the large amount of nourishment necessary for maturation into an imago. When these persistently voracious girls spot edible fruits and vegetables, they go into a relentless munching frenzy as if their ordinary leisurely state were a lie and will even become engrossed and keep eating all day long. On the other hand, even if they were to spot a man who strikes their fancy, the most they'd do is climb up a man's body and try to cling, so these monsters are basically hardly dangerous at all.

However, as they head towards the goal of maturation into an imago, changes occur in the nature of individuals with sufficient stores of nourishment. Their interest in men increases exponentially, and at the same time the odor of the secretion from their antennae also changes to be enticing to men. It consists of a mixture of the secretion they had to begin with and the fragrance of all the fruits and vegetables consumed up to that point, so the secretion of individuals who preferentially fed on mamono realm produce in particular has an extra strong and sweet fragrance which will attract men even more strongly. After wrestling a man lured near them by this, they take his penis deep inside the vagina equipped on their lower abdomen. In this joined state, they make a shell around them with their solidified secretion, shutting themselves inside with the man and entering a ''Chrysalis'' state.

Even after the target of their appetite changes from food to the man, it remains as voracious as ever, and they will be constantly joined together with the man, copulating nonstop inside the cradle-like Chrysalis. Their body, which is specialized precisely for this moment of ''feeding,'' is a soft, squishy lump of flesh that applies pressure to the penis being held deep inside. They repeatedly contract their body like when a caterpillar crawls on the ground, providing endless pleasure and continuously milking semen.

Additionally, it is said that they make the man drink their own secretion via mouth to mouth feeding during copulation. This secretion is condensed with the nutrition that they had continued to store up until entering the chrysalis, and it serves as food for the man while living inside the chrysalis. It sustains his life and keeps his body healthy, while also giving him the energy and stamina to continue copulating without getting worn out. Moreover, the effect that causes exhaustion upon smelling it also remains, and every time the man takes in the odor, his lower body will lose strength, and he'll sloppily ejaculate inside them.

After entering a ''chrysalis,'' they spend their time inside it transforming their body into an imago. By doing this while being satisfied by their husband's semen, they construct the optimum adult body for being impregnated by their husband and at the same time instill their husband with expert knowledge of their body. While spending their time copulating inside the Chrysalis like this, they grow into a beautiful ''papillon'' and achieve eclosion together with their imprisoned husband.

- 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.
- Excess skin behind the head forms something like a hood, and they in fact can pull this up and wear it on their head.
- 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.
- 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.
- 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.
- 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.


## Monster Girl Encyclopedia III | Papillon

**Family**: Papillon
**Type**: Bug
**Habitat**: Plains, forest
**Disposition**: Devoted, warm
**Diet**: Flower nectar

A butterfly monster with beautiful, colorful wings, and the grown form of ''greenworm.'' Having the form of a lovely maiden, if they dance through the sky, their wings shimmer with sunlight, captivating the eyes of those who behold them. It is said that that alone is enough to charm the hearts of men. They are considered beings that symbolize spring, and as if to embody this, the insides of their heads are filled with a warm happiness. Due to their warm personality, they treat anyone with gentle kindness, calming the hearts of those who come into contact with them just like the ''spring season.''

They show warm affection and devotion towards their husband who emerged from the chrysalis with them, as if to repay him for copulating with them countless times inside the chrysalis and providing mana. Shrouded in a sweet, florid charm more so than an obscene allure, they do not attack human men or directly seduce them. If their husband doesn't desire sex, they seem to be happy just spending time at his side and will just try to exert every effort to make their husband's life more pleasant. However, as an imago, the papillon is a form specialized for ''reproduction'' with the goal of producing offspring.

While having sex countless times inside the chrysalis and memorizing the places where their husband looked and touched them, their body matures into an imago, and becomes specialized for arousing their husband's desire. During the larval phase, the odor alluring to males is only released from the feelers, but a papillon's entire body is covered in a sweet fragrance mixed to be even more in line with her husband's preference. On top of that, from all their experience of having sex with their husband inside the Chrysalis, their body transforms so that they can induce even greater pleasure in their husband, resulting in more semen and making it easier to get pregnant. They know this through their own experience.

In other words, their mere presence alone will excite their husband's reproductive urges and spur him to seek intercourse. For that reason they just remain by their husband's side, beautiful and devoted, so that they can always be ready to receive him.

Their larval form specialized for ''eating'' is hungry all the time, but the same thing can be said of their imago form which is specialized for ''reproduction.'' Likened with ''spring,'' the inside of their head is filled with happiness just from living with their husband even without sex, so at a glance they don't appear to be ''hungry,'' but in their heart, they are drooling for more, hungrily longing for intercourse to deliciously eat their husband and add to their happiness. Still, in the proper sense of eating, just sipping nectar from a small amount of flowers is sufficient, however, if a large amount of treats are right before their very eyes, they'll show themselves happily eating with an appetite that shows no sign of abating.

Among the papillons, very rarely there are also those who became a Chrysalis and matured without having been able to acquire a man, and their nature is different than that of normal individuals. Since all the nourishment that was originally meant to be given to a man inside the chrysalis is retained inside their body while their adult body is formed, the resultant body is more voluptuous and plump, and tends to overtly exude sexual charm, and they'll openly flaunt their allure to approaching males. They still won't attack men or directly seduce them, but in this way, individuals appear with a mode of life specialized for getting their hands on a husband one way or another.

- 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.
- 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.
- 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.
- 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.


## Monster Girl Encyclopedia III | Bunyip

**Family**: Lamia
**Type**: Reptile
**Habitat**: The waterside of rivers and lakes, etc.
**Disposition**: Ferocious, timid, cowardly
**Diet**: Carnivorous: wild animals, etc.

A kind of lamia that lurks by watersides. Their body is covered in fur, and their eyes emit an uncanny light. They have a large build for a lamia family monster, and possess both superhuman strength and agility using their long tail as a spring to launch themselves at their prey.

The bestial nature dwelling within them is extremely powerful, and since their reproductive urges are ferocious, they are feared as a race that aggressively attacks men. Despite the ferocity of their appearance, on the contrary, normally they are so quiet that it's eerie, and they live by concealing their body in water in order to hide. For that reason, they are frequently mistaken as ''beasts with bird beaks,'' ''beasts with a giant tail,'' and so on, by many who have witnessed them, and they are often treated as an unidentifiable monster.

They move around inside the water without making a sound, and when they spot a man, after gazing fixedly at him, they launch themselves upon him without so much as a warning. They certainly do look like reasonless monsters launching an attack to kill and devour their prey.

On the other hand, they are beings endowed with high intelligence who also possess enough reason to suppress their bestial nature under normal circumstances. If you can come into contact with them, you'll probably be able to catch a glimpse of their quiet and timid true character too. However, despite being able to converse, it doesn't seem to be their strong point, and they're extremely poor at conversing with men in particular.

For example, from what I've heard, even if they think that they want to become intimate with a man, they aren't able to express it in words, and their head goes blank in the presence of the man, so they become unable to speak properly.

In other words, when they appear to be gazing fixedly at prey, it's actually that they're worrying about how to strike up a conversation with a man, and when they suddenly leap upon him, it's the result of their own urges going out of control due to the confusion.

Typical of lamia, they prefer to coil their serpentine lower half around their husband's body and use their entire body to embrace him. From the way they closely adhere to their husband with the entirety of their body, we can see the obsession with males typical of serpent monsters, but at the same time, the seemingly genuine happiness they appear to exhibit as they draw their face close to their husband makes them also appear just like a little girl hugging a precious stuffed toy and refusing to let go.

Even among the lamia family monsters, their serpentine body is especially soft, and their mana-imbued fur doesn't lose its fluffy feeling even after soaking up water, so they are proud of "feeling extraordinarily good to hug". Their body is devilish in an even different sense than that of a succubus (inma), and it's said that when wrapped in their body, the person embraced will feel so pleasantly comfortable that he'll lose strength and surrender himself.

When they've succumbed to their bestial nature, sex with them is like being mercilessly wrung dry of mana by a monster that's seized hold of its prey: violently ferocious. After losing it, they probably don't feel any resistance to their own state. However, when not in that state, even when coiled around their husband, embracing him, they also appear to blush out of embarrassment for what they had done like an innocent young woman, and then even when having sex, they'll move their hips in a timid manner while paying close attention to signs from their husband. Yet, just like how when prey is taken into the giant maw of a monster lined with sharp fangs, where the slightest little nibble will inflict fatal wounds, even when they barely shake their hips, regardless of the intention of the bunyip herself, violent pleasure will be induced in the penis being snapped up, and the man will be led to ejaculation as if being greedily devoured.

- This monster girl is based on a creature from the aboriginal mythology.
- 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.
- 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.
- 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.


## Monster Girl Encyclopedia III | Owl Mage

**Family**: Harpy
**Type**: Birdman
**Habitat**: Forests
**Disposition**: Calm, gentle
**Diet**: Carnivorous: small animals, etc.

A kind of nocturnal harpy that inhabits the dark depths of forests. They're also called ''forest sages'' since they're endowed with extremely high intelligence and wisdom.

They have a medium-sized physique for a member of the harpy family, and they're plump with many feathers as well, so their flying ability is inferior; however, mana is abundantly stored in their feathers, and they excel at using it to cast spells. Their distinctive large, sharply-glaring eyes give them excellent night vision. On top of that, they are ''evil eyes'' which can put a spell on anyone that makes eye contact with them.

It is said that when locking eyes with them, one's head will space out; one will become unable to think of anything, one will lose one's sense of direction, and be drawn staggering towards them. On the other hand, they have prudent, calm personalities. Normally, many sit still in the forest. For example, even if men encounter them in the forest, under normal circumstances, one can interact rationally with them, and probably even get these erudite harpies to part with some of their wisdom.

However, since they're a kind of harpy, they have a breeding season, just the same. When they enter breeding season, the desire for a human male reproductive partner is overpowering, yet it doesn't cause them to lose control of themselves or become more ferocious. So, in other words, they act as calmly and prudently as usual even while prioritizing satisfying the urge to breed. For the men who are their prey, this makes them even more terrifying huntresses. They hunt under the cover of the darkness of night, and when they glare at their prey with shining eyes, it makes an eerie impression and gives an ominous premonition.

If a man in a dark forest, where he can't see ahead of him, turns his eyes towards a light that suddenly appears, it's their evil eyes, and at that moment he'll end up being put under their spell. Also, the mana contained in their feathers enables them to fly silently, so men are pinned down without even noticing them flying after them, only to end up gazing into their evil eyes filled with the light of desire as they stare down at them.

In this manner, they reign supreme in the darkness of night, during which escape from their eyes is impossible. Just like the ominous premonition felt by their prey, one cannot escape the fate of mating with them.

In general, perhaps because of their active mode of life, most harpies tend to prefer sex with furious movement, but on the other hand, perhaps because of the owl mage's typically sedentary, quiet mode of life, they prefer to take their sweet time enjoying lengthy intercourse with their husband at night. During the day, they prefer to spend their lives such as by quietly embracing their husband's body with their soft, fluffy feathers, mutually touching, and enjoying physical intimacy, after which they may fall asleep just like that.

Also, when having marital sex or spending time cuddling, they have a habit of staring at their husband without ever averting their eyes. During the hunt, these eyes give their prey an ominous premonition, but they just won't take their eyes off their husband due to how much they love him, and continue staring only at him. It is said that these eyes seem unbearably lovely to their husband.

- 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.
- 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.


## Monster Girl Encyclopedia III | Tsurara-onna

**Family**: Spirit
**Type**: Elemental
**Habitat**: Zipangu Region - snowy mountains
**Disposition**: Devoted, lustful, ferocious
**Diet**: Omnivorous, the essence of human men

Ice spirits that inhabit snowy mountains in the Zipangu region, who are gorgeous women with bluish-white skin that make a beautiful, but cold and sharp impression. They share the same origins as the ''yuki-onna'' race, who do look quite similar to them, but compared to the gentle-natured yuki-onna, they are far more succubus-like and have a ferocious disposition. The monstrous nature of this race is readily apparent. The ''ice mana'' contained within them even freezes their own heart, and they're always tormented by feelings of loneliness and desolation. Ergo, they long terribly for the heat that dwells within human men. When a man soon to be prey visits the snowy mountains, they'll try to aggressively launch an attack and violate him, seeking pleasure and debauchery enough to melt their very heart and body.

Just as the name tsurara-onna, ''icicle woman,'' implies, they can convert the ice mana dwelling within them into icicles that they can control. Any prey that resists will have icicles rained down upon him. A man whose body has been pierced by these icicles will not sustain any external wounds, but ice mana will steadily spread throughout his body from the places where he was pierced, inducing feelings of loneliness and desolation so severe that it is hard to resist having his heart frozen. As his heart freezes over time, the man will grow so cold that he will be rendered incapable of thinking about anything, and before long he'll be rendered immobile while curled up and shivering.

The only thing that can thaw the heart once it's been frozen like this is the ''warmth'' that monsters direct towards men. Until being embraced and violated by them, there will be no warmth in the man's heart. If attacked by a monster in that condition, he'll end up surrendering himself, unable to resist the heat and pleasantness of the warmth of the monster intent on melting his heart and body.

Licking her chops over the frozen treat, the tsurara-onna will then bring him back to her dwelling, and then, when her body indulges in the man's essence and warmth, along with that, the woman will pour insanely lewd heat into the man, and the sex they enjoy will practically make them melt into each other.

They want to be in a state where their frozen body is constantly melted by their husband. Ergo, they're extremely greedy for their husband's ''warmth.'' Whether day or night, they'll lie with him, continuously joining with their husband for as long as possible. Of course, they'll try to spend their life copulating in delirium, showering in his essence, and you can bet whenever there's an opening, they'll snuggle up to him and wrap their arms and legs around him, so as to fully enjoy even the warmth of human skin.

Also, in contrast with their violent disposition, they devotedly serve their husband in a manner befitting of a monster of Zipangu, and can even be meddlesome, but they say that pouring love into their husband in this non-physical manner is also one of the things that makes them feel comfortable and produces heart-melting warmth. It may appear to be lady-like behavior at a glance, but compared to the yuki-onna, who has the skill to cajole a man into desiring her himself and taking her as his wife, the tsurara-onna will push herself on a man and violate him whether he says yes or no, pleasuring his body, and she'll exhaustively serve him whether he wants her to or not, delighting his heart. That's how they roll. Even the way that they devotedly serve their husband according to their own desire is like a ''ferocious monster'' who loves her husband.

- This monster girl is based on Tsurara-onna, an icicle that became a woman in Japanese folklore.
- The eyepatch on the profile tsurara-onna is simply a normal eyepatch, she wears it for fashion.
- 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.
- 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.
- 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.''
- The ice jutting from her breasts and arms continues around her back, forming a ring of icicles when she lowers her arms.
- 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.
