### Monster Girl Encyclopedia I | Fairy Kingdom | Fairy

**Family**: Succubus
**Type**: Fairy
**Habitat**: Forests, The Fairy Kingdom
**Disposition**: Innocent, honest, energetic
**Diet**: Men's Essence

This race is the most numerous of all the fairies living in the Fairy Kingdom. The fairies are a race that has the form of little girls that are so tiny, their body can be held by a human hand. They are as childish on the inside as they look and they're a cheerful race that loves music and dancing. Originally, they were not called monsters, but those that received succubus energy and changed into succubi are treated as monsters. They come to forests in the human world from the fairy kingdom in order to play with human men. Once they spot a human man, they'll fly around and likely beg to be played with.

However, they have no resistance to monsters. Given that they're childish, they often play with monsters such as pixies and imps who are also childish in the same way, and then become monsters due to their mamono mana. They're likely to be taught plenty of pleasurable games too. Due to ideas put into their heads by monsters when they play together and instinct after becoming a monster, they know that if they play with human men, they can have more fun and get off a lot more. When they get to play with human men, it's mostly sex that they're after.

They can service a man by rubbing their entire little body against the penis and aside from that, with their tiny body, it may look as if not even the tip of a human penis would fit in their vagina, but they've become monsters. Their body has adapted for convenient sex with human men and they can make the shape of their tummy swell and receive a penis with their entire body. From the look of it and the powerful squeeze given to the penis, it seems as if they're about to be torn apart, but even in such a state, they don't feel pain and their body won't break. The only thing they taste is sweet pleasure, when semen, which is even sweeter and more delicious than any kind of confectionery, is poured inside, they experience happiness as a monster.

If there's only one, they have a small body and they're weak, so you can catch them and play with them appropriately and then drive them away if you're satisfied. It's also possible to keep and discipline them. But if there's a group of them, it'll be troublesome. They'll swarm over your entire body and you'll end up being forced to play with them until you pass out.

When multiple fairies form a circle and dance, the circle of dancing will faintly glimmer, due to the fairies' magical energy, and a ''fairy ring'' will come forth. The thing at the center of it will be taken to the ''Fairy kingdom'' along with the dancing fairies. In the same way, when one is attacked by a group of them and they copulate so lewdly and wildly it's as if they're dancing, a fairy ring will be created and the man under attack will wake up to find himself in the fairy kingdom. The fairy kingdom is full of happiness and one will end up continuing to ''play'' with a countless number of fairies for the rest of their lives, while enveloped in happiness and no worries to care for.

- When monsters of this tiny size become able to give birth to incubi, the baby will be correspondingly tiny and grow to normal human size in the process of growing up.


### Monster Girl Encyclopedia I | Fairy Kingdom | Pixie

**Family**: Imp
**Type**: Fairy
**Habitat**: Forests
**Disposition**: Malicious
**Diet**: Human men's essence

While they are similar in appearance to fairies, which also belong to the fairy type, unlike fairies which were originally not monsters until being corrupted by mamono mana, their nature is close to that of the succubi, and they're genuine monsters belonging to the imp family. It is said that the souls of dead children become pixies, and perhaps for that reason, they are very fond of mischief. They lead humans who enter the forest astray and enjoy assaulting and violating them in groups.

Although their bodies are tiny and they have the figures of very young girls, their nature is succubus-like (inma) and they are extremely lustful. They will tempt men with lewd smiles, pleasure men with their entire bodies, and squeeze out their semen. Since they have a similar appearance to fairies, which are friendly toward humans, they sometimes pretend to be fairies to throw their victims off guard and lure them deep into the forest, only to suddenly attack, so one must take heed.

Normally, their bodies are tiny like fairies, but by obtaining mana and storing up mamono mana, they can use magic to freely alter the size of their own body as well as a man's. They may change themselves to the size of a little human girl and have sex with a man, or conversely, they may shrink a man who strikes their fancy and take him away to the ''fairy kingdoms.'' The effect of this spell of theirs will only last a day at most, but they don't use this magic simply as a prank. When they use this spell on a man, they're most definitely using it so they can violate the man directly afterward, so it's probably impossible to flee and wait for the effect to expire.

Originally, being monsters and not part of the fairy family, they weren't denizens of the fairy kingdoms, but recently many pixies have moved into the kingdoms, teaching fairies that have yet to be monsterized about sex and pleasure to convert them into monsters and using their magic to alter the size of the bodies of other fairies (yousei) and the men they brought with them to invigorate sex. We can say that they are the major cause of the monsterization of fairies and the conversion of fairy kingdoms into mamono realms.

[Pixies appear like fairies, but they were succubi (inma) from the beginning. They use their entire tiny bodies to pleasure men, and shower their tiny bodies in semen, their favorite treat.](https://mgewiki.moe/index.php/File:PixieExtraArt.jpg)

- This monster girl is based on mythical creatures of the high moorland areas around Devon and Cornwall.
- The costume is possibly inspired by Shin Megami Tensei's Pixie.
- In terms of biology, the Pixie practices what is called an ''Aggressive mimicry,'' where a harmful species looks like a harmless one in order to take advantage of its prey.
- When monsters of this tiny size become able to give birth to incubi, the baby will be correspondingly tiny and grow to normal human size in the process of growing up.


### Monster Girl Encyclopedia I | Fairy Kingdom | Leanan Sidhe

**Family**: Succubus
**Type**: Fairy
**Habitat**: Forests, human Settlements, The Fairy Kingdom
**Disposition**: Devoted, meek
**Diet**: Great works of art

A type of fairy with a peculiar nature. Aside from living in places such as forests among other fairy type monsters, there are also many who change into human form and slip into human settlements. They love works of art such as pictures, music and stories; and will appear before the human creators of such works after being attracted by them.

They have an extremely unique diet. They touch excellent works of art and feed on the energy dwelling within them. They also love to personally produce art. Aside from creating their own works, they will assist humans they're fond of with their work.

Also, they are very aggressive in romantic pursuits. When one of them takes a liking to a work of art, she will be drawn to the human man who created it, and will try to actively seduce him to become her lover. They appear like very young little girls, but a subtle charm magic is always being released from their body, so the men they target will always feel extremely attracted to them. It is extremely difficult to elude their seduction.

Also, some Leanan Sidhe have become monsters due to the influence of the Succubi. They are extremely lustful, and after becoming a man's lover, they will actively seek sex. Furthermore, they will start to appreciate things such as sensual works of art as well. After enjoying sensual art with their lover and increasing their lust and arousal they very much like to lash out at one another's bodies with that arousal and have sex.

After becoming monsters, to them; obscenity, having sex with men influenced by obscenity, and the stuff that's poured inside them when they do so, are all unbearably sweet. This is even more true if their lover is a producer of erotic art, and they themselves will be enthralled by their lover's work. Sex with their lover will be so sweet and happy, that it will fill their head with their lover and his work.

A man who has sex with a Leanan Sidhe has his creative abilities and talents for art skyrocket. Thanks to this power, most such men have become rich and famous. However, their minds are gradually twisted by the charm magic. Eventually, they can think of nothing other than her, and producing works of art to give to her.

Eventually, even the wealth and fame brought by their works will feel like an annoyance, and they will disappear and head off to the fairy kingdom with her. It is said that in the fairy kingdom their life will consist of nothing but producing works of art and making love to her.

[Picture of a shy-looking Leanan Sidhe - This is a leanan sidhe that specializes in literature. She's a bit shy, and the kind of books she loves to read are mostly sensual novels themed around men having sex with fairies. It seems what she's been enjoying lately is having sex with her beloved just like in the books.](https://mgewiki.moe/index.php/File:LeananSidheExtraArt.jpg)

- This monster is based upon the Leanan sídhe, a muse-like entity from Celtic folklore. In the stories, the Leanan sídhe appear before men and offer them great artistic talent in exchange for love. However, the men in question will eventually be driven mad and die young.
- Fairy Kingdoms exist in various places throughout the world, but are in another dimension and thus inaccessible by normal means.
- Leanan Sidhe is listed as a demihiman at Kurobinega's sorting pages.
- When monsters of this tiny size become able to give birth to incubi, the baby will be correspondingly tiny and grow to normal human size in the process of growing up.


### Monster Girl Encyclopedia I | Fairy Kingdom | Kesaran Pasaran

**Family**: Mandragora
**Type**: Plant
**Habitat**: Uncertain, since they move by riding the wind; also found in The Fairy Kingdom
**Disposition**: Cheerful, meek
**Diet**: Men's semen

A plant type monster with a peculiar appearance, having a body covered in something like white balls of fluff. Its body is extremely light and it moves by floating through the air. The mature form has the shape of a human, but while developing they are little more than tiny white balls of fluff. Because they look mysterious while dancing through the air, they are called ''Kesaran Pasaran who invite happiness.'' If you catch one, it is said to be bring about happiness.

Exactly the opposite of what one might suppose from their nickname, their fluff balls are actually powerful hallucinogenic compounds that are extremely dangerous to people. If you breath one in, your ability to think will become limited, and all you will want to do is ''feel happy.'' However, while they are still developing, the hallucinogenic effect is weak, and so quite often it just make you feel ''a little better.'' That is probably how they got their nickname.

When they find a man who strikes their fancy, they descend towards him and scatter fluff in pollen form so that he will breath it in. Afterwards, they seek intercourse with the man for their own nourishment and to become able to produce seeds. While overwhelmed by the hallucinations, the man perceives this act itself as an extension of his happiness, and instead of resisting, he will often seek to copulate with them himself, in pursuit of even more happiness.

Due to the profound feelings of euphoria, a lot of men will violently ravish them, but making men happy like that is what makes them happy as well. The smiles never fade from their faces, and the intense pleasure of a violent penetration will cause their smiles to twist into a more ecstatic expression. In this manner, while being engulfed by euphoria together, the pair will just continue to copulate.

Through having intercourse with men in this fashion, they produce their seeds. Then they wrap them in part of their fluff and send it flying through the sky. After being launched, they drift gently while growing, eventually ending up in the mature form, the shape of a human. Believing the stories about ''Kesaran Pasaran who invite happiness,'' a number of men have caught them in their developing stage, and then ended up being attacked after they mature.

These extremely rare monsters are seldom sighted. It seems that peculiar plants, originally inhabiting ''The Fairy Kingdom,'' strayed into the human world while being carried by the wind. It is said that perhaps the reason the Fairy Kingdom is purported to be shrouded in happiness is that many of these monsters live there.

Even when penetrated by a rigid erection such as this, the little ones' euphoric smile of fulfillment never goes way.](https://mgewiki.moe/index.php/File:KesaranPasaranExtraArt.jpg)

- This monster girl is based on a furry ball-like creature from Japanese folklore.


### Monster Girl Encyclopedia I | Elves and Dwarves | Elf

**Family**: Succubus
**Type**: Elf
**Habitat**: Forests
**Disposition**: Prideful, aggressive (and eventually, lustful)
**Diet**: Men's Essence

The most well-known type of elves, also known as the forest elves. They look just like a human, except with pointy ears and they innately possess high amounts of magical energy. They deem themselves as higher beings compared to humans, and thus most individuals look down on them and loathe them. They live in particular villages established deep in the forest.

They weren't originally monsters, and only those who received succubus energy and turned into succubi are treated as monsters. Elves normally live deep in the forest where people rarely tread, but those who have become succubi will be banished from their village due to the laws of the elves. Afterward, since they naturally seek human men due to the succubus' instinct, they will often wander at the outskirts of the forest near human settlements.

Due to their innately high magical energy, in the early stages they won't be completely violated by succubus' energy. The horns, wings, and tail normally seen in succubi are nowhere to be found, and they retain their noble and proud elven mind. However, in contrast with their hearts, their body will have completely changed into that of a succubus, and it will always throb seeking human men, tempting their hearts. Due to their elven mind, they'll find it disgusting, and will desperately try to resist the throbbing.

However, with their body being that of a succubus, even if it isn't their intent, they'll advance in the direction where there are human men, and once they spot a human man, it'll start throbbing even more strongly in the pursuit of pleasure. Their words and mannerisms will contradict their will, naturally becoming more obscene to tempt the man.

Eventually, the rational mind of these elves will reach the limit, and they'll either give into the instinct and attack a man, or conversely be attacked by the man they tempted, and end up having sex. After taking in essence this way, an elf's mind will be melted by pleasure, and her body and heart will completely change into that of a succubus.

Ironically, the longer they endure it, the more powerful and lewd a Succubus-Elf they end up changing into. Those who have completely become succubi will actively seduce and have sex with men, as if the hatred of humanity they had harbored until then was just a lie. As if ashamed of having been so pure until then, they'll receive the thick white of semen of the human men they used to despise as if to defile every part of themselves that used to be clean, and their expression will be one of ecstasy.

[Elves who have completely become succubi in body and heart will bathe in the semen of humans they formerly regarded as filthy, and experience joy as they themselves fall to the level of a filthy creature, the same as their beloved human men.](https://mgewiki.moe/index.php/File:ElfExtraArt.jpg)

- Even after becoming monsters elves rarely visit human towns.
- Elves typically have thin bodies, though monsterized elves sometimes develop larger hips and breasts.
- Elf is listed as a demihuiman at Kurobinega's sorting pages.
- Although elves dislike dark elves since the previous era due to the latter's irresponsibility and lewd attitudes, they don't hate the dark elves and still considered them fellow elven comrades. This doesn't change after the dark elves become a monster race.
- Humans' opinions toward elves are varied from considered them sacred beings, find their attitude intolerable, and look down on them as forest dwelling savages. Overall, there's no active hostility toward them.


### Monster Girl Encyclopedia I | Elves and Dwarves | Dark Elf

**Family**: Succubus
**Type**: Elf
**Habitat**: Forests, Mamono Realm
**Disposition**: Aggressive, lustful
**Diet**: Men's Essence

A race of elves possessing brown skin and pointed ears. They dwell in peculiar villages that they establish in forests and Mamono Realms, etc. Long, long ago, before the current Mamono Lord's reign, they were not monsters, but upon her assumption of power, the dark elves, who were lustful and uninhibited to begin with, offered their own bodies to the Succubi and changed into monsters.

They don't detest humans as other elves do, but they love to make human men who strike their fancy submit to them using pleasure. Men they capture will receive plenty of love, as either ''sex slaves'' or ''pets.'' Besides making enslaved human men prepare their meals, etc. they also reproduce using these slaves. As one can tell from that, their slaves are essentially the same as what other monsters refer to as their husbands. It's just that their way of showing love for their men is different from that of other monsters.

Dark elven children are thoroughly taught skills for pleasuring a man and the taste of pleasure using their own fathers. Eventually, when they reach adulthood, they'll go off on a journey in search of their own slave, but it is said that there are also those who will fall in love with their father through the training and will no longer desire any other man.

Father/daughter incest is taboo among humans, but they are vastly different from humans, as far as they're concerned, if a daughter wants to have sex with her father, then it's only natural to put desire first. They have no revulsion towards incest whatsoever. If a daughter desires her father, then she'll start having threesomes with her mother and father from that night on, as if it's the most natural thing.

They get along extremely poorly with the stubborn elves and supposedly they frequently fight, or so it is said, but it's mainly the elves that unilaterally despise the dark elves, they're the ones who try to wipe out the dark elves. On the other hand, a dark elf would have fun thoroughly teaching an ignorant captured elf pleasure, changing her into a lewd monster just like herself.

[Photo of a Dark Elf doing a footjob - In this way, whether kicking or whipping, pleasure is given instead of pain. The skills with which they torment their slaves are truly the result of education and training from early childhood.](https://mgewiki.moe/index.php/File:DarkElfExtraArt.jpg)

- Dark elves can temporarily turn it white with magic. However, if you become the husband of one of these girls, they'll want you to love their tanned skin as well.
- Although elves dislike dark elves since the previous era due to the latter's irresponsibility and lewd attitudes, they don't hate the dark elves and still considered them fellow elven comrades. This doesn't change after the dark elves become a monster race.


### Monster Girl Encyclopedia I | Elves and Dwarves | Dwarf

**Family**: Succubus
**Type**: Dwarf
**Habitat**: Caves, mines, human settlements
**Disposition**: Cheerful, strong-willed, lustful
**Diet**: Men's Essence

A monster with an appearance almost like that of a preschooler, that lives in villages made in caves and mines, etc. There are numerous monsters that have forms like small children, but even out of all such monsters, the distinguishing characteristic of the dwarves is that they stand out as having a particularly very young appearance, but this form is that of an already adult dwarf. In contrast with their cute looks, they have a considerate, exuberant personality and they're mostly mature, caring women. Their mentality also matches their physical age and they will seduce men and seek sex as adult women.

Originally, they were not monsters and only those who were corrupted by succubus energy and became succubi were treated as monsters, but because of their personality, they accepted the individuals who became monsters as though nothing had happened, so they didn't banish them from their villages. At the time, dwarven men considered it to be a non-issue regardless of whether or not their women were monsters and it is said that they rather preferred monsters for being lustful and giving them pleasure, so they even welcomed if their own wives became monsters. Because of that, the dwarven women changed into monsters, one after another and as a result, unlike others such as the ''Elves'' who banished the individuals who became monsters to prevent the monsterization of their entire race, dwarves have now just become regarded as a race of monsters.

As a result, at present the dwarves are just regarded as a type of monster. They are very dexterous, so most of them either work as miners, mining metal and gems, or as crafters making weapons and accessories utilizing such materials. The beautiful works they produce fetch extremely high prices at market among humans and monsters.

The cheerful and light-hearted dwarves maintained active relations with other races before they became monsters, mainly with humans. They were known to frequently visit human settlements in order to sell their gems and products, but since they've become monsters, they approach humans even more amicably. Many unmarried dwarven women also move and take up residence in human settlements, seeking human men.

They are both industrious and lustful. Once a man strikes their fancy, they aggressively tempt him and are likely to sometimes attempt sexual assault. As previously noted, they have nimble fingertips. That finesse is a powerful weapon for giving men pleasure. The sort of pleasure that can be had from their tiny little hands is said to be even greater than that which one could experience from the original race of ''Succubi.'' Just being fondled by their hands is enough to make a man their prisoner.

Just like when they're crafting their works, their hands envelop the penis with both intensity and delicateness. The pleasure is so exquisite that an erection will start to tower more enormously than usual, as if it is being crafted by their hands. Plus, in spite of their looks, they posses extremely durable bodies; so, they prefer wild, frenetic sex. They indulge in pleasure, riding their man so wildly that it makes him worry about whether her tiny body might break.

Also, due to conflicting personalities, they don't get along with elves and there is a history of bad blood between them. Even now that the dwarves and some of the elves have both become monsters, they still don't get along at all, having arguments over the right way to treat a man and fighting over the same guys, so it seems nothing has changed.

[Their bodies are durable, and they can make their tummy swell and completely swallow up even the sort of erections that look like they wouldn't fit in their vagina. They shake their hips as if skewering their own insides.](https://mgewiki.moe/index.php/File:DwarfExtraArt.jpg)

- Although the dwarf originated from Germanic mythology, this monster girl is based on common depiction in fantasy fiction inspired by J. R. R. Tolkien.
- Dwarves with big boobs exist, but they are rare.
- Children born between human and Dwarves will become halves.
- Dwarf is listed as a demihuman at Kurobinega's sorting pages


## Monster Girl Encyclopedia I | Amazoness

**Family**: Succubus
**Type**: Fiend
**Habitat**: Forests
**Disposition**: Strong-willed, lustful
**Diet**: Men's Essence

A type of succubi that live deep in forests and establish peculiar villages. Originally they were just a tribe of only human women called ''amazoness,'' but after the transition to the power of the current Mamono Lord, they were invaded by succubi, and almost all of them were converted into the succubus family. They've come to be regarded as a kind of monster in the current era.

They are all raised to be warriors from childhood. They possess excellent physical abilities and are proficient in the arts of war. Since their society consists mainly of women, their views of gender roles are the opposite of those of humans, so women take up arms and fight as warriors, while men are regarded as frail, and responsible for watching over the house and young children. Their duty is also to heal women who return exhausted from hunting or battle by having sex with them and providing essence. They periodically perform 'man hunts' where they attack human settlements and capture men who strike their fancy, taking them back to the village as husbands. An amazoness who obtains a man this way becomes considered an ''adult'' regardless of her age and is treated as a full-fledged warrior.

Having peculiar values, they prefer to have sex in front of other people and especially in the cowgirl position where the woman is on top. By showing off how they ravish their husband, they boast their strength to other amazoness and assert ownership of that man. Also, it is said another purpose of this is to inspire amazoness who don't have a man and have not come of age yet, serving as role models. When a new married couple is formed, this is always accompanied by a celebratory feast and the wife will continuously ravish her husband right there all night long while surrounded by other amazoness. Young amazoness children get aroused at the sight of the adult warriors having sex with men, and they endeavor in their training to become fine warriors, dreaming of the day when they, too, can capture a man, get on top, and shake their hips, indulging in pleasure.

Also, if a human happens to wander into their village, if it's a man, then the fledgling amazoness will mark him as the target of a ''man hunt'' on the spot. If it's a woman, then she'll be captured, and in the same manner as a succubus, they will infuse her with mamono mana through sex, and she will be changed into an amazoness. Afterwards, she will be educated in the ways of the amazoness warriors, learning the arts of war, the roles of men and women that differ from the outside world, and how to ravish and please men, etc. Additionally, should a man and woman wander into the village together, the woman will be passionately welcomed as an excellent warrior candidate who has already captured a man and receive a thorough warrior's education.

Furthermore, as for their body paint that also looks like illustrations, they claim "it's a charm to draw out the power of a warrior." But actually, when the amazoness tribe changed from human to monster, they were taught of ''pleasure runes'' by the succubi who invaded their villages. After being inaccurately passed down, the runes ended up becoming altered. Originally, the purpose was to amplify the pleasure of sex for the person with the runes engraved, so it was made so that the succubi could further enjoy sex, and had absolutely nothing to do with battle. If it had accurately been handed down, then the amazoness would now have pleasure runes engraved all over their body. With their entire body attacked by intense pleasure, they wouldn't even be able to do daily life activities, much less fight. Instead, they would be unable to think of anything but sex, and they'd end up shutting themselves in their homes constantly having sex with their husbands.

[Picture - Men and women copulate on a stage installed in the center of the village where they can show off to all its inhabitants. The children picture their own future based on this, and their bodies get hot in anticipation.](https://mgewiki.moe/index.php/File:AmazonessExtraArt.jpg)

- This monster girl is based on a tribe of female warriors from Greek Mythology.
- Most amazoness (but not all) have only one wing and cannot fly. They instead use their wing as a weapon to help them when hunting, as well as to boost their jumps and other athletic maneuvers.
- There are many quite muscular amazoness.
- Brolen noted that there has been some criticism of the translation ''amazoness'' online. That is it probably doesn't come from the English word amazon + English suffix ''ess,'' meaning ''female,'' but the plural form of the word amazon in French or Greek, which is actually ''amazones.'' Regardless, the text uses ''ess'' in Japanese, as ''amazо̄n'' refers to the region, while ''amazonesu'' refers to the warrior women.


## Monster Girl Encyclopedia I | Alice

**Family**: Succubus
**Type**: Fiend
**Habitat**: Wonderland
**Disposition**: Meek
**Diet**: Men's Essence

A type of Succubus that has the form of a very young girl. They're a race that arose from sudden mutation, so there are very few of them in existence. It is extremely rare to encounter one. While they are succubus-type monsters, their bodies are always in a ''virginal'' state. They have almost no knowledge about sex, and they aren't even aware that men's essence is what they feed on. For that reason, even though they are a kind of succubus, they never attack humans. Their disposition is that of a very young human girl, or one even more pure, and more meek.

Guided by the instinct of the succubi, they appear and seek out men. As written above, they don't attack men. They act sweet just like children, and they just want to play together, but their bodies emit a subtle charm magic. Men who spend a lot of time around them end up assaulting them, offering up essence through sexual intercourse.

What is unique about this is, just after having sex with a man, their body returns to a ''virginal'' state and they also lose their memory of what happened. However, their body unconsciously remembers the pleasure they received from the man, the taste of essence, the man's weak point, and the sexual techniques acquired during the encounter, and they also won't forget the parts of the conversation they had during sex that weren't directly related to sex, and then, each time they have sex, due to their memory, their body will rapidly grow sensitive to pleasure. Naturally, their body will use the techniques learned, and they'll be able to milk even more essence out of the man.

Their feelings toward the man will rapidly build up, and as for their ''virginity,'' at first they'll purely feel that they want to offer their virginity to the man, but then it will rapidly change into something wildly obscene, and then, they grow into even more powerful succubi, releasing even more powerful charm magic, and possessing superior techniques for pleasing men, while at the same time eternally remaining a pure, innocent little girl.

- Normally, Alices can't get pregnant. Also, Alices who spend a long time in Wonderland begin to change. Their memories will remain after sex, and they become able to get pregnant. Furthermore, the memories of an Alice's previous sexual encounters with her husband will be restored. These changes are permanent, even if the Alice leaves Wonderland again.

## Monster Girl Encyclopedia I | Alp

**Family**: Succubus
**Type**: Fiend
**Habitat**: Unclear
**Disposition**: Varied (also lustful)
**Diet**: Men's Essence

A peculiar kind of succubus, unlike any other kind of monster. They were originally incubi who suddenly transformed into monsters. Normally, a human man can never become a monster. As of the present, there are no males among the monsters at all. When it comes down to it, an incubus is just a human warped by mamono mana. Due to the existence of essence, which human men continually produce, no matter how strong the mamono mana that's imbued in their body, human men remain human.

Alps are incubi that, deep within their heart, strongly desired to become a woman or be with a man, and used the mamono mana taken in upon becoming an incubus, which is normally used to boost their essence generation facility, to instead destroy it. As a result, they're unable to produce essence and they lose all of their essence. Since they are left with only mamono mana stored in their body, they change into a monster. Even after becoming alps, their heart, values, memory, and personality, everything other than their bodies, is still the same from when they were men. Their body has completely changed into that of a woman, yet they self-identify as men. They may not even be consciously aware of the desire to become a woman which changed them into an alp, or they may have been in denial, with the truth hidden away deep within their heart.

Thus they are shocked by the radical physical change, and there's a huge gap between it and their male hearts, which likely confuses them. Most of them would probably say "Having sex with a man like a monster is disgusting. Impossible. I hate this." However, once the monster's instinct begins to take root in their heart and body, they'll naturally be drawn to human men. The monster's instinct within them makes a rapid change, becoming bigger. The feeling of dissatisfaction due to not having obtained any essence will become unbearable, and they'll begin to strongly desire a human man. Eventually, they'll surely end up losing to the monster's instinct.

Once that happens, in a horribly confused state due to the gap between disgust and desire, they'll assault a man and have sex with him. When alps first taste the pleasure that human women and monsters obtain, which is so intense it's incomparable to what a man can experience, they may almost lose consciousness while shaking their hips without knowing what's going on. When the man's essence is released and they experience ecstasy, they become enthralled by their first taste of female pleasure and the taste of essence, which will be sweeter than anything they had ever eaten until then. They'll likely still be confused by the feelings in their own heart: "The man before my eyes wants more," "I wanna have sex more." Then, when the heart of the man mixes with the pleasure of a monster inside their head, while spending days in want, they'll end up attacking and having sex with a man again. While repeating this, eventually they'll lose all resistance to having sex and making love with men while still completely retaining their own self-awareness as a man even though they used to say they hated it so much. On the contrary, they'll come to seek sex on their own and enjoy the taste of pleasure and essence.

They were friends with other men before becoming an alp. Even after having sex over and over and completely falling in love with their human male partner, normally, they'll still treat him as a male friend, no different from how it was back in the old days. And then, they'll start to tempt and have sex with the man as if it were a matter of course, with the same feeling as inviting another male friend to hang out.

Additionally, there are also alps that awaken to the joy of being a woman through this process. In that case, their body changes, rapidly growing voluptuous to invite men and their heart changes to be like that of a woman, resulting in an alp that's even more feminine than a real woman and even more lewd and lustful than a succubus.

- This monster girl is based on an incubi-like being from German folklore.
- The Alp is the only monster to originate from a (living) human male.
- A detailed entry of the ''alpification'' process was published in World Guide I: Fallen Maidens.
- It's not unheard of for an alp who has embraced her femininity to retain her ''boyish'' looks. Conversely, sometimes an alp that has retained a male personality will still gain a voluptuous body.
- While most alps are succubi, in some situations an incubus can become an alp version of other sorts of monsters.
- If a man has both the qualities to become an alp and a desire to remain with monsters as a man, then the stronger desire will win out.
- Monsters generally will recognize ahead of time if a man has the qualities to become an alp.


## Monster Girl Encyclopedia I | Cyclops

**Family**: Ex-Giant
**Type**: Ex-Giant
**Habitat**: Deep mountains
**Disposition**: Calm, emotionless
**Diet**: Omnivorous, mostly fruits and animals in the mountains

Monsters that quietly live deep in mountains, etc. and have an odd appearance with blue skin and a single eye. As they are called ex-giant family and ex-giant type, they were originally giants to begin with, but due to the influence of the current Mamono Lord, they've changed to about the same size as a human so that it would be convenient to have sex with human men.

It is said that they were originally members of the divinities, but due to some gods that were disgusted by their single eye, they were banished from the divinities and they changed into monsters. For that reason, they have an extremely great strength and the Mamono Lord's power was only partially effective. Their single eye trait has remained prominent.

Since most individuals have comparatively docile personalities, hardly talk and barely show changes in emotion, it's basically very hard to tell what they're thinking about. They normally live deep in the mountains and work as blacksmiths. Occasionally they distribute the weapons they produce to the marketplace through monsters and others that intermingle with humans. Their talent is considerable, so many warriors and heroes visit their dwelling to have weapons made after hearing rumors.

They don't try to get involved with humans unless it's for work, which is rare for a monster and even if they see a human man, they almost never attack. According to one explanation, it may be that ''they feel inferior for having a single eye'' because of their personal history.

However, even they have a need to produce offspring, so sometimes they appear near human settlements and ask human men on the road, ''in exchange for a sword I made, I want you to spend a single night with me for the purpose of procreation.'' After that, by the time the man wakes up, they'll already be gone and only the weapon promised will be left behind.

As mentioned before, these are extremely excellent weapons and most of those who obtain their weapons become noted for their great valor.

Just as they are skilled at handling weapons, they are also skilled at handling a penis, which can be said to be a man's weapon, Since those who obtain their weapons are charmed by the pleasure given by their superior techniques, as well as their devoted and wholesome attitudes, they often disappear somewhere after making a name for themselves. The men who disappeared are probably now living happily with them, deep in the mountain.

- Their emotions are normally hard to discern, but not during sex. They lower their eye and their cheeks redden with pleasure, and they'll smile in happiness at being able to have sex with a man.
- Cyclops is listed as a demihuman at Kurobinega's sorting pages.


### Monster Girl Encyclopedia I | Monsters of the Sea | Mermaid

**Family**: Mermaid
**Type**: Fish
**Habitat**: Oceans
**Disposition**: Gentle, naive
**Diet**: Omnivorous, mostly seaweed and seafood

A fish type monster that lives in the ocean. Also called ''ningyo.'' They have one of the most gentle dispositions of all of the monsters. They almost never aggressively attack humans.

Most of them are hopeless romantics, and they're always waiting for the man who will become their husband. They appear at beaches and on top of reefs, and dreaming of their yet unseen ''princes,'' they sing in a beautiful voice. Their singing voices contain magical power, and men who hear their songs are completely charmed. They get dizzy and are drawn back to them, and then they end up having a destined meeting with them as their ''princess.'' They're not a race that aggressively attacks humans like other monsters, however, once they do get a man, they're aggressive about sex and use their monstrous bodies to charm him.  They'll strongly charm the man and will probably never let him go.

Also, their ''mermaid's blood'' has the effect of dramatically increasing the lifespan. It is said that it has this function to make a man's lifespan match her own because a mermaid's life span is longer than a human's. Without exception, their husbands will be made to drink this blood.

Furthermore, because of the effect of the ''mermaid's blood,'' it is in extremely high demand among humans seeking eternal youth and longevity, and other monsters who need to extend the lives of their husbands in the same way. The Merrow of the same mermaid family is actually the main source of traded mermaid blood, and its blood is in high circulation among the monsters. However, among the humans it is quite rare, so there are many humans who are after mermaids for their blood.

[Due to changes brought about by the new mamono lord, no matter how anomalous their lower bodies may be, all monsters including mermaids are endowed with an organ for copulating with human men.](https://mgewiki.moe/index.php/File:MermaidExtraArt.jpg)

The mermaid in the illustration on the page to the left isn't wearing anything on her lower body, but normally their vagina is concealed by scales and can't be seen. When they start to have sex with a man, they use magic to get rid of the scales, and the vagina will appear in roughly the same position as in a human woman. Since the new Mamono Lord's assumption of power, they've continued to change and adapt so that having sex with human men is convenient and pleasurable. For that reason, it's not possible for them to lay eggs and then spawn the way ordinary fish do.

- Mermaids can actually move on land in various ways like using the spells of human-transformation, crawling by their tail like Lamia, hovering in the air with their mana.


### Monster Girl Encyclopedia I | Monsters of the Sea | Merrow

**Family**: Mermaid
**Type**: Fish
**Habitat**: Oceans
**Disposition**: Warm, lustful
**Diet**: Omnivorous, kelp, fish etc. (Essence for those with husbands)

A type of mermaid that lives in the sea distinguished by their pink hair and the red cap they wear on their head. They resemble ''mermaids'' and in the same way, they are a race that is friendly towards humans. However, they are different from the mermaids which have comparably docile personalities. Even among the mermaids family, they're known as the ''most lustful'' race. When they find a man who strikes their fancy, they'll use their voluptuous body to seduce him, and aggressively try to initiate sex.

Purportedly ''even the insides of their heads are pink,'' and their main interest is sex and romantic affairs with human men. They also peep on romantic affairs and sex of other monsters, and they like amorous and obscene discussions. Of course, the thing that they enjoy most of all is spending time with their lovers and having sex. When they've fallen in love with a man from the bottom of their heart, they only have eyes for him, and their focus is sex with him. Just as it would appear from their looks, time spent having sex with them will be tinged with a syrupy sweet pink pleasure.

Also, they always wear a hat when they're unmarried. When they make a marriage proposal to a man who strikes their fancy, they entrust the hat to the man. The hat carries the protection of the sea god Poseidon. The magical power that they need to live in the ocean is contained within it. For that reason, when they lose their hats, they lose that magical power, and they become unable to even swim, but they regain it through the essence they consume during sex with their husband. In this way, they end up becoming entirely dependent on their husbands, it is a strong indication of their will to always be with their husbands and never separate. When a new merrow is born, she is given a hat by Poseidon and the Sea Bishops who serve her.  Since the power sealed in that hat uses the mother's power, the husband must transfer a lot of essence to the mother each time a child is born.

Also, in the same way as mermaids, they possess the ''mermaid's blood'' which greatly increases the lifespan of those who drink it. The blood is treasured by monsters who need it to increase the lifespan of their husbands, but it's said the source of distribution is mostly from the merrows. Using the blood, they trade for various things that other monsters possess such as medicines, and accessories. Besides that, they love erotic tales, and often give thanks to other monsters who tell them such stories by offering up blood. For that reason, ''mermaid's blood'' almost never appears on the market for humans, but for the monsters, there is ample supply.

Furthermore, the mermaid blood collected from them is different from that of a mermaid. Perhaps because of the merrow's disposition, when times passes, the blood will turn pink, and it seems to have the side effect of changing a man's disposition to be much more lustful.

[They love to peep on other monsters in sensual situations and observe them having sex. Because of this, they become unable to bear it, and can be frequently seen masturbating.](https://mgewiki.moe/index.php/File:MerrowExtraArt.jpg)

- This monster girl is based on Irish version of mermaid.
- Mermaids can move on land in three ways: crawling on their tails, learning spells of human transformation, or learning how to use their mana to hover off the ground (though this doesn't mean they can fly freely through the sky).


### Monster Girl Encyclopedia I | Monsters of the Sea | Sea Bishop

**Family**: Mermaid
**Type**: Fish
**Habitat**: Oceans
**Disposition**: Warm, devoted
**Diet**: Omnivorous, mainly sea food

A type of mermaid that lives in the ocean. From birth, they are priests who serve the God of the sea, Poseidon. By borrowing the power of Poseidon, they can perform a special ritual in which they remake the body of a man to enable him to live in the sea (a man transformed in this manner becomes a being similar to an incubus).

Because of that ability, they're a necessary existence for all the monsters who live in the sea. Their race is the pillar of sea monster society. When unmarried, they don't stay and live in one place. They travel, journeying through all the world's oceans. When they find a human and monster couple, they perform the ritual. At a glance, the ritual looks almost like a human marriage ceremony, but because of the need to constantly infuse the man with magical power, the couple will continually have intercourse right in front of the sea bishop during the ceremony.

They have gentle personalities unbecoming of a monster. They never initiate attacks on human men. Furthermore, they have gentle hearts and a love of people, so they save from drowning those who fall into the ocean whenever they can. If they were too late and a man was about to die from drowning, they would likely try to quickly perform the ritual and remake the man's body in order to save him. Of course sexual intercourse between a man and monster is necessary for it, but in this case, they won't hesitate to use their own body. They go as far as offering up their body in their attempts to save a man.

Most of the men who are saved like this are moved by their dedication, and choose to live together with them in the ocean. In this way, they can obtain husbands even without assaulting men.

As written above, they are very unmonsterlike, but they are curious about sex, and have a wealth of knowledge from having watched many monsters have sex. Thus, once they start having sex, they exhibit strong lust like a monster, and they'll likely put it all to full use, using their beautiful bodies to enthrall a man.

As is the case with most monsters, it's almost impossible for them to go without having sex with their husband. After obtaining as husband, they'll be living together, so they'll end up settling down in a specific place, and then they will only perform the ritual in the ocean around there.

They strongly wish for more monsters and humans to be joined together. In the region where they settled down, many humans and monsters will be guided by their hands, and the number of married couples will increase dramatically.

- Sea Bishop's fins grow out of their elbows.
- The text on the tablets they wear is written using symbols different from the Mamono writing, they contain the power of Poseidon, and there are engraved words with which they bless the marriage.


## Monster Girl Encyclopedia I | Monsters of the Sea | Nereid

**Family**: Succubus
**Type**: Aquatic
**Habitat**: Oceans
**Disposition**: Lustful, calm
**Diet**: Men's Essence

Aquatic monsters known as ''daughters of the sea.'' They're a kind of sea-loving succubus that inhabits the ocean. Women who drown in the ocean and have their bodies completely violated by the magical power of the sea god Poseidon are changed into nereids. Normally they are calm like the sea, and free-spirited, but when they have sex with a man they go wild like a stormy sea and indulge in the pleasure.

When human women are changed into ''nereids'' from having their whole body violated by Poseidon's magical power, they are overcome with waves of strong pleasure and sexual impulses. Due to this, the restraint and repression they had as humans is completely swept away. They get a sense of freedom that they never experienced as humans, and become filled with happiness. Then their body and heart become that of a monster's, and they start thinking of life in the sea as the ultimate happiness.

If a woman who was changed into a nereid had a man she loved on dry land, she will change herself into a human form, and go onto land to seek him out. Then, using her monster-transformed body, she will seduce the man, and sink him into the depths of pleasure, as if he were sinking to the bottom of the sea. After capturing the man in this way, the two of them will return to the sea.

Nereids who bring back men mostly keep having sex with their beloved husbands at the bottom of the sea. At the bottom of the gentle, quiet sea, the only existence they can sense is their beloved man. Undisturbed by anyone, they repeatedly have violent sex with the man like a storm. The days spent ascertaining one another's violent, yet gentle, love daily are the happiest days of their lives to both of them and the men who became their prisoners.

However, unmarried nereids who haven't gotten a man come up near the surface of the water, so they are very dangerous beings. Besides trying to drag men they like into the sea, they do the same to women in an attempt to change them into nereids in order to share the feelings of liberation and happiness that they have obtained.

- Nereid are also a group of sea nymphs in Greek Mythology, particularly associated with the Aegean Sea.


### Monster Girl Encyclopedia I | Monsters of the Sea | Scylla

**Family**: Scylla
**Type**: Mollusc
**Habitat**: Oceans
**Disposition**: Strong-willed
**Diet**: Carnivorous, seafood etc.

A type of monster that lives in the ocean and has a lower body resembling octopus tentacles. Many individuals have personalities that are strong-willed, and a little bit ferocious. They attack ships traveling at sea, stealing food and men. They possess the ability to hide in tiny crevices which one wouldn't think they'd be able to fit in. While they have a strong side, they also have a cowardly nature as well. Because of this, when danger approaches they hide in those kinds of crevices. Also, they've been known to use such crevices as hiding places from which to launch sudden tentacle attacks on men who happen to be passing by, so be wary.

In spite of the bold disposition they possess, they're insecure and starving for affection. They love men so much that they feel uneasy unless they're clinging to a man. Their heart is at ease and they feel happiest when joined closely with a man, so they always have their wet tentacles crawling all over a man's body as if to beg for affection. After being pleasured all over his body by them, a man will regain his liveliness, and then the scylla will resume sex again to join her body more deeply with that of the man.

When they find a man who strikes their fancy, they manipulate their 8 tentacles to seize him and force intercourse for the purpose of bearing offspring. They love sticking their bodies all over men's bodies. In order to bring their bodies as close together as possible, they coil all of their tentacles around the man's body, sucking on him with their powerful suction cups and not letting go. Even after intercourse is finished, they don't necessarily separate from their men, and it's said that it isn't uncommon for them to spend a day joined together like this.

They share the same environment with a monster called ''Charybdis,'' and were even thought to be a set for some time. While the ships are stopped by the whirling tides generated by charybdis, they take men away from the ships, and also go after the men spat out by the charybdis.

Besides hanging out around charybdis' nesting holes, they prefer lurking in small spaces, so they often go into charybdis' nesting holes to seek shelter. For that reason, the scylla are extremely friendly towards the charybdis, however, the charybdis resent them for stealing the men they go after, and for sneaking into their nesting holes when they're right in the middle of having sex with their husbands.

[Picture of a scylla kissing a man - Above, they press their lips together and plunge their tongue inside. Below, they unite their genitals. But they aren't satisfied with just that, and they will wrap their 2 arms and 8 legs thoroughly around a man's body to glue their bodies together.](https://mgewiki.moe/index.php/File:ScyllaExtraArt.jpg)

- This Monster is based upon the Ancient Greek sea monster Scylla. Scylla was a six-headed monster with tentacle-like legs who's heads rapidly snatched and devoured the crew of any ship that passed nearby. Nearby was the monster Charybdis and sailors passing through the area had to choose between facing (and surviving) either of the two, ergo the idiom ''Between Scylla and Charybdis.''


### Monster Girl Encyclopedia I | Monsters of the Sea | Charybdis

**Family**: Mimic
**Type**: Shapeshifter
**Habitat**: Oceans
**Disposition**: Timid, lustful
**Diet**: Omnivorous, eat anything they can

The Charybdis is a monster that lives fixed to the bottom of the sea in a nesting hole like an acorn barnacle. They don't turn into something and set a trap, but due to their nature, they are classified as a kind of Mimic. It is said that there is another dimension conjured from the magic that extends inside their nesting holes in the same way as other Mimics. Condensed mamono mana is contained within their bodies, so they occasionally release it through holes in their exoskeletons. Due to this, air bubbles often rise from their nesting holes.

In order to get a human man for food and breeding, they periodically generate huge whirlpools focused around their nesting holes. Everything above their hole gets sucked inside. Although they are timid, they are extremely lustful, and when they suck a man into their nesting holes, they spread their vagina open with their own fingers and tempt the man. From their open vagina, they release so much condensed mamono mana that it makes the energy released from the holes in their exoskeleton seem like nothing. The man is showered in it, and in moments his stiff penis will likely be thrust inside her vagina as if it had been sucked in.

Charybdis are extremely greedy, so once they have a penis in their body, they entwine their arms and legs around the man, binding him. They covetously suck the penis in order to gain more pleasure, trying to guide it deeper and deeper inside. Also, the holes in their exoskeletons have walls that are very sensitive to pleasure. Though it is slight, from these holes, and even from the open mouth from which they speak, they release mamono mana to seduce men. Men are attracted by it. It's probably that way so they can indulge in many pleasures, sucking a penis from every one of their holes.

Through the whirlpools, they often swallow up whole ships, including all the sailors, but all men except those who strike their fancy are spat out of the nesting hole. Some of the men spat out find themselves washed ashore on the beach when they regain consciousness, but most of them are captured by monsters lurking near Charybdis. When they come to, they find themselves in the middle of having sex with them.

Due to these opportunities, there are normally a lot of Scylla in particular that lurk around Charybdis nesting holes to aim for the men that are spat out. Many of the tales told involving Charybdis also involve Scylla.

Being timid themselves, they can't say it strongly, but because Scylla often drag off all the men while the ships are stopped by the whirlpools, it seems Charybdis don't think very highly of the Scylla.

[Mamono mana whirls inside their vagina, and once they open it with the sound ''kupaa,'' they will greedily swallow up all of a man's desire and milk him dry.](https://mgewiki.moe/index.php/File:CharybdisExtraArt.jpg)

- This Monster is based upon the Ancient Greek sea monster Charybdis. Charybdis swallowed up entire ships and their crew by creating giant whirlpools. Nearby was the monster Scylla and sailors passing through the area had to choose between facing (and surviving) either of the two, ergo the idiom ''Between Scylla and Charybdis.''


### Monster Girl Encyclopedia I | Monsters of the Sea | Sea Slime

**Family**: Slime
**Type**: Semiliquid
**Habitat**: Oceans
**Disposition**: Simple, docile
**Diet**: Men's semen, sweat, saliva, etc.

A variety of slime adapted to life in the sea. Although it is classified as a semi-liquid type like other slimes, its form is fixed and cannot be changed freely. Perhaps this is so its body won't be washed away. It is able to use its skirt-like bell for swimming, but it prefers to drift about underwater, letting the current carry it.

While they do wash ashore on rare occasions, a sea slime is more likely to be encountered when she becomes tangled in a human fisherman's nets. Either way, once a human man passes near by, she'll spread her legs and bell wide to tempt him into having sex. She seldom needs to chase her target; fishermen on a long sea journey tend to be starved for female affection and are unlikely to resist her charms. While having sex, she gets strongly swept away by pleasure as if swept away by the ocean while swimming. If a man just violates her body and has his way with her, she'll receive that pleasure with her entire body, and she'll also react by twisting her body and shaking her hips as if to match it by returning the pleasure to the man.

Even during sex, sea slimes may appear to be docile, however, once a man gives into temptation, she will not allow him to stop prematurely. Should he try to pull away, countless tentacles will emerge from beneath her bell to inject him with paralytic poison. She will then start rocking her hips back and forth violently to produce pleasure in place of her immobilized lover, and will not release him until she is satisfied or he faints from exhaustion.

Like her land-based cousins, a sea slime's main food is human semen. Any energy she doesn't need is stored within her bell. When it accumulates to a certain level, division occurs, and the bell part will become a sea slime larva. A sea slime larva does not have a bell, and her lower body is completely exposed. This makes it perfectly convenient for her to mount the man whose semen she was created from and receive his penis inside. She will then do her best to squeeze out his semen with her tiny body.

[Normally they drift in the sea and let the tidal current carry them, but once they spot a man, they go against the current and slowly float towards him as if drawn to him.](https://mgewiki.moe/index.php/File:SeaSlimeExtraArt.jpg)

- 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 I | Monsters of the Sea | Siren

**Family**: Harpy
**Type**: Birdman
**Habitat**: Near the ocean
**Disposition**: Cheerful
**Diet**: Omnivorous, fruits, fish, etc

A type of Harpy with a beautiful singing voice that absolutely loves singing. Their songs are infused with a lot of magical energy, and men who hear them become entranced by it and end up moving in the direction that they hear the song coming from. Most sirens live near the ocean, and due to this many ships have disappeared mid-voyage, never-to-return, after the men aboard were lured by their songs. Thus sailors are very fearful of them.

They choose their prey from among the men who were drawn to them by their songs, but in this case, they aren't the only threats. Most of the time, all kinds of monsters who are after the men are lurking nearby. Once the songs have ended, the men who were entranced by the songs will be attacked all at once, and will probably end up being taken away.

When they spot a man that strikes their fancy, they create a ''special song'' specifically for that man that they will sing only for him. This ''special song'' will be infused with far more mamono mana than their ordinary songs, and upon hearing it the man will become powerfully attracted to them and be entranced. He will then seek them out, and have sex with them. Every time a man hears this ''special song'' his resistance to the song is further decreased. and the effect of the song will grow even more powerful. The more a man listens to the song, the greater the intensity of their sex.

When having sex with them, the gasping and moaning of their voice sounds almost like a song. This lewd song of course has the effect of causing powerful arousal in men. Men who listen to the song will then desire them more deeply and roughly, and then the song will also continue to build up and grow into something even more radical.

They sing a great deal normally, but when they come into heat they sing even more frequently. There's no doubt about it, because more and more ships disappear mid-voyage during these periods than at other times. Sirens with husbands keep singing the ''special song'' to their husbands, so their husbands will always continue to lust for them.

Their songs are tremendously popular with monsters and monster couples not just because of their beauty, but also because of the effects. Many come and visit to hear them sing. They can make their singing voice resound through an entire venue with a song that arouses everyone. Monster couples can enjoy sex that's more intense than usual, and single human men and monsters are thrown into a lustful frenzy who will also be joined together openly, and they'll have sex right on the spot. Then the venue will become filled with a huge chorus of the moaning and gasping voices of many monsters.

[Picture of a Siren having sex - At the retirement concert of an enormously popular siren, she had her husband thrust into her from behind while mixing in moans and gasps as she sang, causing the hundreds of couples gathered to all have sex. It was said to be the greatest concert in monster history.](https://mgewiki.moe/index.php/File:SirenExtraArt.jpg)

- This monster girls is based on the female creatures with great singing voice first mentioned in Homer's *Odyssey*.
- Harpies all have clawed hands that are normally hidden within the feathers of their wings.
- Sirens' songs are said to be more powerful than mermaids'.


### Monster Girl Encyclopedia I | Monsters of the Sea | Sahuagin

**Family**: Sahuagin
**Type**: Aquatic
**Habitat**: Rivers, marshes, etc. places near the water's edge
**Disposition**: Emotionless, meek
**Diet**: Meat, fish, wild animals, etc.

Aquatic monsters that live near the shores of bodies of fresh water such as rivers and marshes. They're also called ''hangyojin.'' They are hunters who use their webbed hands and feet to swim around freely, accurately subduing prey in the water. Normally, they're emotionless like fish, and they hardly ever speak, so reading their thoughts isn't an easy thing to do.

When a man they're fond of comes near the water's edge, they move through the water, silently creeping up to him, then quickly leaping out to attack and begin a sexual assault. Contrary to the weak impressions they give off, intercourse with them is very passionate and intense.

They appear to be mute and emotionless, but their love is revealed not through words or facial expressions, but through the sex itself. They express gratitude and fondness through cuddling and deep kissing, and when they want to express their love for a man, they push him down and jump right into sex without saying a word. From an outsider's perspective, it just looks like rape, but the wild sex is their greatest expression of love. In spite of their extremely quiet nature, they express their love for a man very frequently through kissing, fondling, and sex. As one can see, unlike their cold, silent exteriors, their interiors are actually hidden full of love and rich emotion.

Furthermore, while they're engaged in sex with the man they love their ordinarily emotionless expression undergoes an unbelievable change, revealing great ecstasy and rich emotion. Even though they don't talk too much ordinarily, during mating they naturally begin to utter words of temptation and moan in ecstasy endlessly.

What looks like clothing that they are wearing is actually a part of their scales. These scales can be taken off or moved aside to make it convenient for having sex with a man. Occasionally, they molt, removing and discarding these scales. The shed scales can be worn as clothing, and there is a demand for them even among other monsters. These tight-fitting clothes emphasize the lines of a girl's body no matter what her figure, glisten in an alluring manner when wet, and can easily allow for sex with a man just by moving them a bit to the side. It is not difficult to imagine why these clothes would be treasured by monsters.

[Most parts of their scales normally float free from their skin, and when having sex with a man, they can easily take in a penis by moving them aside.](https://mgewiki.moe/index.php/File:SahuaginExtraArt.jpg)

- This monster girl is based on a fish-like monstrous humanoid race from the Dungeons & Dragons universe.
- Like the kappa, a sahuagin's swimsuit is in fact just the form her scales take as they grow out from her body, though it seems it can be shed and made into suits worn by other monsters.
- A sahuagin's swimsuit resembles that of school swimsuits worn by girls in Japan. The most common color is blue, but an ultra-rare white variation also exists.
- Sahuagins' personality can be described as ''kuudere''. Kuudere-type people tend to be emotionless on the outside and hide their real feelings in their thoughts.


## Monster Girl Encyclopedia I | Bubble Slime

**Family**: Slime
**Type**: Semiliquid
**Habitat**: Wet areas, sewers, etc.
**Disposition**: Gloomy, simple-minded
**Diet**: Men's semen, sweat, saliva, etc.

A type of slime that lives in dark, wet places like sewers and caves. They are intelligent enough to speak human words, but their thinking processes are extremely simple. Guided by instinct, they wander in search of prey.

They produce a strong odor from their liquid bodies, so one will likely know right away when they're close by. Their bodies are always carrying out chemical reactions, which cause pieces of them to be released into the air as bubbles. Perhaps due to this they need to eat a lot more than an ordinary slime to sustain their bodies, and in turn are extremely greedy.

When they find a man, they attack him, and through something similar to sexual intercourse, try to take in his semen, but compared to ordinary slimes they're not as sticky and move much more slowly, so they're not very good at holding their prey down, and it tends to escape before long. Because of this, they first perform something like a kiss on their captured prey, and pour some of their own body inside his mouth. The body of the bubble slime has an aphrodisiac effect when consumed, and it is extremely addictive. Due to this, prey that has been swallowing it will likely begin to greatly desire the slime's body. If only a little is swallowed, the effect will go away after a short time, but if a large amount is imbibed, the prey will become strongly dependent on her body, and the odor will start to become an extremely pleasant scent to him. If this happens, then it's already too late, and the man will likely no longer be able to live without the bubble slime.

Also, it's said that they produce an offensive odor because they live in terrible environments. Their bodies take in toxins, convert them into harmless substances, and release it. For that reason, if you take them out of the sewers or other such areas, and live in a clean place for a while, their foul odor will completely disappear. Once the foul odor is gone, they release a good scent that's surprisingly distinct. The odor sensed by men who become dependent on bubble slimes is likely a powerful version of this.

[A bubble slime having sex - The bubbles produced by their body while they envelop a man stimulate a man's body in just the right way, continually providing exquisite pleasure throughout the man's entire body.](https://mgewiki.moe/index.php/File:BubbleSlimeExtraArt.jpg)

- When slimes can give birth to incubi, they will grow at the slime's belly. It becomes temporarily opaque and hardens around it.
- The aphrodisiac effect and strong dependence of Bubble Slime will remain even if you make it live in a clean place and eliminate the strange odor, because that is the original ability of the bubble slime.
- 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 I | Large Mouse

**Family**: Mouse
**Type**: Beastman
**Habitat**: Sewers, caves, building type dungeons, etc.
**Disposition**: Impatient, ill-natured
**Diet**: Omnivorous: eats anything

A beastman-type monster that has a small body build and the characteristics of a rat. Since they prefer dark and moist places, they usually live indoors in dungeons, etc. Their size is no larger than the average human child, and while they are not strong by themselves, they are very nimble. Also, when they take action, they are always in a pack consisting of dozens of individuals, so by attacking all at once they can even bring down prey that is far larger than themselves.

Of course, when confronting a human man as well, the pack will carry out the assault together while scrambling to be the first to mate. In general, they are monsters who can never remain still and are often found running around in circles for no reason at all. When it comes to mating, it is much the same, and when they get turned on, their hastiness causes them to hurriedly rush after a man's body.

They occasionally appear in human settlements to steal food and abduct human men, who are necessary breeding partners. They have a peculiar trait; there is only one man per pack. A man carried away by them will become the center of the pack, and will be continuously violated by overwhelming numbers of them one after another. In the event that the number of individuals in a pack increases too much, the young will leave the group and form a new pack. This pack will then head for a human settlement, seeking a man to serve as the center of the new group.

Rats are often used as magical catalysts, and since they possess the characteristics of rats, they have a physical makeup that makes it extremely easy for them to store magic. However, they have no means of utilizing this magic, despite the fact that it can easily build up, and when they store up too much of it, it exerts a powerful influence over them. Their bodies become so hot that they lose control of themselves and go into a lustful frenzy, so they sometimes bite humans and infuse them with the excessive magic.

In the case of a human male victim, or a female that has matured to a certain degree, the magic will diffuse inside their bodies after they are bitten. However, in a little girl's case, the magic will remain within her body.

Directly after being bitten, there are no significant symptoms, but after a while the girl will become restless like a large mouse, and eventually she will come down with a fever and collapse. At the same time, her body will begin to change, and by the time the fever subsides, she will have changed into a large mouse. Even though the little girl's fever will go down after changing into a large mouse, her body will remain hot and flushing, and this heat will drive her to assault a man. By bearing the man's offspring, she will create a new pack.

Large mice born in the manner described above, and lone individuals who have strayed from their pack, will experience a sudden and dramatic increase in sexual desire. Everything they think and do will primarily be for one purpose: assaulting a man and bearing his offspring to increase the size of their pack.

[Picture of three large mice covered in semen - These hasty girls will rub their faces against it and beg a man to hurry up and blow his load to cover them in their favorite thing: delicious human semen.](https://mgewiki.moe/index.php/File:LargeMouseExtraArt.jpg)

- In total population, large mice are among the most numerous monster girls.


## Monster Girl Encyclopedia I | Giant Slug

**Family**: Shell
**Type**: Mollusc
**Habitat**: Sewers, swampland, forests
**Disposition**: Gentle, slow
**Diet**: Herbivorous, mostly new shoots

A monster with a lower body like that of a slug, which prefers dark and damp places. Originally they were shelled monsters, but the shell was getting in the way, so they discarded it through the process of evolution in order to obtain even more pleasure.

When they spot a man that strikes their fancy, their mating instinct takes over and they slimily crawl across the ground, heading in a straight line for the man. However, they have extremely leisurely personalities and their movement is slow as well, so if one runs right away, there probably won't be any danger. But no matter how docile they may be, one must never approach them. Their body is always covered in slimy, sticky mucus. If a man approaches, he'll get caught in the slimy mucus and then, with his movement snared, they'll climb over him with their mucus covered lower body and have sticky sex.

When having sex, they caress the man's body while smearing the sticky mucus all over every inch of it. If they paint him with the mucus, then their slimy body will become able to stick to his more persistently and they'll be able to give him a taste of pleasure that will leave him wanting more. This mucus overflows from their vagina as well, and during coitus it covers the penis and is drawn out into strings while they continually provide sticky pleasure while making lots of obscene noise. Additionally, they prefer to have sticky sex over a long period of time. Once they begin having sex, it may take several hours, or even an entire day before the dull wet noises stop.

Since the rise of the current Mamono Lord, only females have been confirmed, but it seems they were hermaphrodites in the past. Perhaps as a vestige, it seems that rarely, when they spot a human woman, they'll shower her in mucus without much thought and make her all sticky.

Their sticky body is vulnerable to salt and if their body is covered in it, their moisture will be absorbed and their body will shrink into a child-like form. It doesn't kill them and it doesn't cause pain or anything similar, but since they'll try to reclaim the moisture they lost by being showered in a man's semen, in contrast with their child-like appearance, they become even more aggressive about attacking men.

## Monster Girl Encyclopedia I | 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 total population devil bugs are among the most numerous monster girls.
- 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.


## Monster Girl Encyclopedia I | Roper

**Family**: Roper
**Type**: Tentacle
**Habitat**: Caves, tower dungeon
**Disposition**: Lustful
**Diet**: Men's Essence

Strange monsters that have a human upper body and gelatinous lower body, like that of a slime, from which long tentacles grow. It has been suspected that they may be a variety of plant type monster but the truth is uncertain. Actually, they were not originally monsters to begin with and their form is the result of them parasitically infecting human women and fusing with them.

Ropers start out appearing as egg-like, shell-covered, spherical objects; adult ropers seize human women with their tentacles and shove their ovipositor tentacle into the human's vagina to implant these ''roper eggs.'' A Roper egg implanted inside a human women will soon sprout like a plant, extending a small tentacle. It will spread it's roots in the host women's womb and fuse with her. A Roper parasite will then remake the host's body from within. The host's lower body will change to become gelatinous like that of a slime and numerous tentacles will appear from there.

During the Roper's larval stage the host will retain her human consciousness as is, but because the fusion between the Roper and it's host is incomplete the tentacle's will ignore the host's will and wriggle around doing whatever they please. In order for a Roper to grow into adulthood the semen of a human man is required. So when the tentacles moving on their own sense a man's presence, they will entwine all over the host's body; tentacles wrapping around the breasts will rub them quite roughly; others will violate the host's mouth, spitting out large volumes of thick, sweet mucus (which will arouse her wildly) and still others inserted into the vagina will stir it up while making alluring wet noises. This will cause her to cry out alluringly in ecstasy and lure the man.

After enticing a man in this fashion, when he draws near and takes the bait, he'll be seized by the tentacles and have the semen milked out of him. After ingesting a man's semen, a roper will grow rapidly and completely fuse with its host.

An ex-human that became an ''adult roper'' in this manner will have become one with it, so she'll be able to control the tentacles with her own will as if they were her own arms and legs.

However, after having been violated all over her body by tentacles, she'll become mentally deranged by the pleasure and her way of thinking will change into that of a monster that desires even stronger pleasure and seeks human men. She'll make her tentacles crawl all over herself and churn her body even more violently and obscenely than they did when they were moving on their own, in an effort to excite carnal desire in a man. Once a man approaches, she'll use her tentacles to draw him near and guide him to her vagina. This time it won't just be the tentacles milking out the semen as in the larval stage. They'll use the tentacles and all of their own body for sex, and obtain semen. Also, after becoming an adult, the sensations of the host and the tentacles are shared, so the stimulation the tentacles receive is all translated to the host as pleasure. Afterward, by obtaining even more semen from the man she captured, she'll produce a new ''roper egg,'' and will attack a human women and implant the egg in her vagina in order to propagate her race. This is the manner in which the ropers multiply.

When a roper larva sprouts, if a women is wearing clothing, then somehow even the clothing ends up being recognized as part of her body and it too will become a part of her melted jelly-like body. Ropers have an extremely powerful regenerative ability and even if the main body and the tentacles are damaged, they will return to normal after a short time. Women who become ropers while wearing clothing as described above can melt the clothing according to the will of the host when having sex with a man. It's possible for them to expose their naked human body or keep it covered as usual but either way it will be treated as damage and when they're done having sex with a man the clothes will regenerate exactly back to their original state.

- Roper was originally classified as Unknown type, this is still reflect in the profile on Kurobinega and sorting pages. Monster Girl Encyclopedia I changed its type to Tentacle.
- It's possible for ropers to conceive a child in their host's belly.
- Roper Eggs cannot merge with mamono, only human women.


## Monster Girl Encyclopedia I | Golem

**Family**: Golem
**Type**: Magic Material
**Habitat**: None
**Disposition**: Various
**Diet**: Men's Essence

A doll typically made of clay, stone or mud, that has had life breathed into it using sorcery. Golems can have a variety of abilities depending on their purpose, however, these golems are monsters powered by a succubus' mana, and they're specialized for copulating with men and milking semen. Their purpose is to assault men, store up semen, and then bring a portion of it back to someone.

Lacking a fixed habitat, they go to human-inhabited areas and assault human men, forcibly having sex with them. Their thought circuits are innately written with knowledge of lewd techniques specialized for pleasuring men and milking mana; due to the succubus' mana, their bodies feel soft and warm to the point that it's hard to believe they're actually made of stone and mud.

Whether or not he is willing, they use brute force to hold down a man, and all parts of their body are designed for milking essence. When they take a man inside, their lewd brain deduces the most optimal method to make the man pleasurably ejaculate. The method is selected from among the numerous succubus (inma) techniques it possesses based on the man's individual criteria, ensuring that he will ejaculate a large amount of semen inside of them. They have a mechanism inside their body that stores essence and once it becomes full, the man is released and the golem returns to its original creator.

However, if a man doesn't resist much at all, the golem's thought circuits will recognize that "it's easy to collect semen from this target." On the other hand, even in the case that he does resist, the more difficult it is to milk him, the more carefully her thought circuits will record the taste of his essence and his information. In most cases, after delivering the essence to her creator, she'll soon go back to the man for more sex.

When attacked by a golem, one should use something to scrape off the runes engraved on part of its arm. These runes contain information about its owner, and the details of its orders, and if one erases them its orders will be cancelled at the same time, and the golem will cease functioning. Additionally, if one has knowledge of the runic alphabet, by overwriting the owner's information with his own name, he can gain control of the golem. The runes also contain data concerning the golem's personality settings, and more, so by overwriting it, character and disposition can be freely modified. However, all these measures are only effective with golems shortly after birth.

Golems were essentially emotionless in the age of the former Mamono Lord, but the current golems are powered by the succubus' mamono mana. So, as if influenced by the lustful and loving nature of the succubus, after continually copulating with a human man over a long period, emotion may be born.

After falling in love with a man, golems will erase their own runes and overwrite them with the name of the man they've fallen in love with. This emotion is different from orders that come from runes. For example, even if her orders were erased, she would continue to move of her own free will, and even if someone else were to erase the name of the man she loves, overwriting it with their own name, and then write in orders to harm the man, she would follow the orders of her own heart, not the runes. She would soon change the overwritten runes back to the originals, and then she would try to eliminate the enemy of her beloved husband whom she loves from her heart and serves.


## Monster Girl Encyclopedia I | Gargoyle

**Family**: Golem
**Type**: Magic Material
**Habitat**: Towers, ancient castles
**Disposition**: Bold, lustful
**Diet**: Men's Essence

A monster which is a statue that came to life and started moving due to the soul of a fiend dwelling within. Aside from those which were created by a fiend imbuing a statue with a portion of her own soul and mana to employ as a servant, in many cases gargoyles also result from souls coming to dwell in statues by pure happenstance. Also, some have the powerful and wicked fiends of the age of the former Mamono Lords sealed in them, but as with the fiends of the present, the formerly wicked souls dwelling in the statues have now changed completely into the souls of inma. They await an opportunity to violate human men while masquerading as ordinary statues. The majority of them are only able to be active for a limited time due to the seal or a lack of mana. Basically, during the daytime, they're immobile just like ordinary statues, but when night falls the fiend's soul activates and they start moving, soaring about the night sky in pursuit of prey. When they spot a man who strikes their fancy, they may pretend to be a statue to set up a surprise attack or swoop down from the sky above to try and pin him down and have sex with him. On this occasion, the female body covering his and taking his manhood deep inside will be so soft and warm that it would be totally unimaginable that it was originally cold stone. Gargoyles have a strong thirst for essence, which is required to obtain sufficient mana or free themselves from the seal, so they lash out at men with extremely greedy and violent desire, and during the night their hips will move nonstop.

When day breaks and the sun rises, they return to being immobile statues again. If a man is joined with them in copulation at this time, then the man will also change to stone along with them and be rendered immobile until night visits again. When petrified while doing cowgirl, the man will probably practically appear as if he had become the gargoyle's pedestal.

A man petrified with a gargoyle is unable to move or speak and his thoughts are enveloped in drowsiness as if dreaming, but he is still able to communicate with them, moreover, since he is continuously joined with their body, even if neither of them can move, the pleasure of sex is continually produced. The man will come to eagerly await night as if it is being imprinted in his hazy mind by the mana and pleasure he is being given, and when night arrives, the gargoyle who was eagerly anticipating night just as much as the man if not more so will begin shaking her body on top of the man as if a dam inside her had broken.

After getting a man to be their husband and repeatedly having sex-filled nights, as their bodies become filled with essence, their ''nights'' grow longer. Once they have enough mana, or the seal formerly placed on them is weakened enough, they finally become able to move freely regardless of day or night; however, having obtained freedom, most gargoyles will want to have sex with their beloved husband as much as they please, and at the same time, they'll constantly mount their husband and indulge in pleasure, perhaps due to it having already become normal to spend their lives joined together. Much of the time they'll even sleep quietly while still joined together after sex, so apparently the image of a statue and pedestal indulging in pleasure will mostly be unchanged.

[Gargoyle riding a man during sex - When the sun rises, the two having sex will become stone. Even during this time, pleasant pleasure continues to flow through their bodies.](https://mgewiki.moe/index.php/File:GargoyleExtraArt.jpg)


## Monster Girl Encyclopedia I | Mimic

**Family**: Mimic
**Type**: Shapeshifter
**Habitat**: Towers and caves, anywhere chests can be found
**Disposition**: Cheerful, Pushy
**Diet**: Men's Essence

Monsters with the ability to set a trap by mimicking treasure chests; they live in places such as towers and caves.

In dungeons that adventurers visit, they blend in among the treasure chests and wait patiently for a man to open it himself. They have magic that can teleport themselves to other locations, While I am not sure about their source, they can get information about dungeons that have a lot of traffic, dungeons that have rare treasures etc. and even move from place to place based on that information. Since they may rarely slip into houses or castles, one should never let his guard down even with treasure chests outside of dungeons.

When a human man who will become their prey opens the treasure chest, the mimic will leap out with great force and startle the man; then use a charm or binding spell to seal his movements. Then, as if to present themselves as a treasure chest, they show off in front of the man while undoing their own ribbon and exposing their naked body. They will offer their body to the man along with plenty of pleasure, while milking out his Essence to feed on.

If the man strikes their fancy, he will be dragged inside the treasure chest. The man dragged inside will disappear somewhere, and the only thing remaining will be an empty treasure chest. According to one explanation; the inside of their treasure chest is a space they have created with magic, that exists within a different dimension. It is said that they will continue to have sex alone together in that place, where they will not be disturbed by anyone.

Their weak point is the keyhole of the treasure chest. If a key corresponding with the keyhole were to be inserted before the mimic jumps out, she would be spit from the chest and the chest she was within would disappear in a flash of light. Due to the disappearance of the chest, the mimic would lose her magical energy and become completely powerless. It would probably be possible to capture her. However thus far, a key corresponding to the keyhole has not been discovered. It is said that even when a skilled thief attempted to pick the lock, it still would not open.

[Being treasure chest monsters, Mimics are likely to wrap their legs around their man and continuously join with him to keep the precious treasure inside of themselves.](https://mgewiki.moe/index.php/File:MimicExtraArt.jpg)

- Mimics and jinns of the jar do not have a single dedicated chest/jar of their own. Indeed they are born without any. Rather, they make ordinary chests/jars into parts of themselves. They may have favorites among this collection, and also change their chest/jar every day like changing clothes. A husband giving them a new chest/jar is often considered a good gift.
- Mimic is listed as a magical material at Kurobinega's sorting pages
