Monsters
The life forms called monsters all have different traits and values than humans, and they think and behave based on those. I'll explain the unique ecology and values of monsters so that you the reader can grasp the differences and similarities compared with humans and understand them better. However, even though we generalize them all as monsters, there are actually many different races of monsters that exist. For example, since all monsters seek to have sex with human men, most of them have no resistance to discussing it and related topics. But among them, there are some that have a strong sense of shame, or pride, and for that reason, there are also some races that would normally hesitate to discuss the topic of sex. However, it's certainly true that even they are far more lustful compared to humans, and once their devilish nature awakens, they display the same lasciviousness as other monsters.

So, it is extremely difficult to make a sweeping generalized introduction to these beings known as “monsters” which include a mix of a variety of races with different ecologies. The ecology of monsters that I'll be describing here is very generalized and only applies to the average monster, but on the other hand, please bear in mind that it's the form revealed by the fundamental essence that all monsters share in common.

Concerning Monsters
Monster is a general term for various races that are reigned over by the Mamono Lord.

Formerly, in the age when the old Mamono Lord ruled the monsters that is called “the age of the former mamono lords”, monsters were grotesque creatures that devoured humans and spread death. However, since an immensely powerful succubus took over and became the new mamono lord, we've entered an age called “the new Mamono Lord's age”, and the monsters forms have changed dramatically. All of them now have beautiful, alluring figures resembling human women. They attack humans, just as they did when they were grotesque creatures, however the meaning behind it is completely different.

The monsters of the present have been heavily influenced by the nature of the Mamono Lord who is a succubus and their main food is the same as that of the Mamono Lord, living essence called “Spirit Energy” that is contained within the semen, saliva, etc. of human men. Also, just as it appears, all of the monsters are female. Presently, a male monster has never been confirmed. For that reason, when they reproduce, they must have sex with a human man. And more than anything, in general, all “monsters” are lustful, and instinctual. They are devoted to pleasure and desire, especially the desire to have sex with men. Due to these goals, they coercively have sex with human men, and attack them in order to rape them.

Races of Monsters
No matter what, “monster” is a general term for various races. By definition, monsters don't have “mana” within their bodies beforehand, and each race has its own unique “mamono mana”, but due to the influence of the Mamono Lord, all monsters ended up having “succubus' mamono mana” inside their bodies as well. Humans, elves, angels, etc., races other than monsters, have mana within their bodies, but when they are assaulted by monsters, etc. , they get violated by mamono mana, mana is driven away and expelled and it disappears so that they are twisted like monsters, and so these races of women are also treated the same as monsters.

If we classify the monsters into rough categories based on appearance and disposition, we can divide them as “beastman type”, “demon type”, “reptile type”, “undead type”, etc., and then we can classify them more minutely by tying together races with similar forms and traits such as ''{Note from Jekkers: Someone link all these family and monster types to their categories. I'm too lazy to do it right now. Delete this when you're finished.}'' "lamia family" “wolf family” “succubus family” “harpy family,” etc. Additionally, the lamia family can be divided into the smallest units, “races” such as Lamia, Medusa, Echidna, etc. But even monsters of the same family can differ wildly in form and traits depending on the race. Monsters are beings that are extremely rich in diversity.

In the other volume, “Monster Girl Encyclopedia I”, various races of monsters were introduced in detail with illustrations. In the introductions from the encyclopedia only one individual is portrayed in the illustrations, but of course they have individual differences. Physique, facial features, clothing, etc. things that aren't set by the race's inherent special traits, vary depending on the individual. However, from a human standpoint, in the case of individuals of the same race, they often feel like they have a similar atmosphere about them for some reason, and since there are a lot of points that are similar or matching in terms of looks and personality, someone knowledgeable can distinguish the differences between races with similar forms, and even someone with little knowledge can probably sense it: “Are these two the same race?” “Although they look similar, I think they're different races.” The illustrations in the monster girl encyclopedia are the average forms of those races in general. Basically, it's okay to think that most individuals look similar to the illustration.

Origin-race and Sub-race
In the explanations of monsters, the words “original race”, “sub-race”, etc. are sometimes used. “Original races” are the monsters that founded the races of monsters classified in families such as “XXX family”. For example, for the lamia family, it's Lamia, for the slime family, it's Slime, etc. Amongst all the monsters of XXX family, the original race is the oldest race. It is supposed that most of the monsters belonging to XXX family derived or evolved from the original race. They have the basic nature of monsters of XXX family, and the original race is fundamentally supposed to be the most numerous of all monsters in the XXX family. Sub-race is a general term for monsters that derived or evolved from the original races. For example, Medusa and Echidna are regarded as sub-races of Lamia, the original race. Sub-races are distinguished by having parts of their form and nature in common with the original species. If they have high abilities or special abilities compared to the original race, they are often described as “higher races”, but humans just call them that. With a few exceptions, the monsters themselves aren't aware of any kind of hierarchy based on that.

It is easy for peculiar sub-species to emerge in special environments. In the desert region, snowy region, Zipangu region, etc. many peculiar monsters unique to those regions can be seen. “Mutated races” are extremely special even amongst sub-species. As the name suggests, they come from mutations of the original race. Queen Slime is a mutation of Slime, Aliceand Alp are mutations of Succubus, Hobgoblin is a mutation of Goblin, etc.

When the original race reproduces, mutations may be born very rarely. Also, sometimes they are only born under extremely special circumstances. Compared to the original species, they have a hugely different nature and traits, so we are treating them as a different race out of convenience, but technically they are just varied individuals of the original race. When a monster of a mutated race reproduces, the children born won't be monsters of the same mutational variant, but children of the original race. For example, if a hobgoblin has children, goblins will be born. If an alp has children, succubi will be born. However, when monsters of mutated races reproduce, the chance for a mutant to be born is slightly higher than normal. After a very long time, it is eventually possible for them to become an independent race of monsters. Additionally, this will be discussed in a later item, but for monster mothers and monsters of the original race, the birth of a mutant monster is an extremely happy event.

Spirit Energy
Most monsters feed on the vital essence “spirit energy”, that human men have a lot of. They absorb it inside their body and convert it into “demonic energy”, the vital energy of monsters. For monsters, spirit energy is a delicious treat that is far better than any other kind of food. Monsters that obtain and taste spirit energy will be engulfed in powerful ecstasy and joy. Even monsters that mainly eat things besides spirit energy can still take in spirit energy and convert it to demonic energy. To them, a man's energy is a sweet treat.

spirit energy is plentiful in human bodily fluids, especially semen. Besides drinking it through their mouth and ingesting it, they most prefer to milk it out using their vagina by having sex with a man. Since spirit energy is mainly taken in through sex in this manner, while “sex” is an act of reproduction for monsters, at the same time it is also “feeding.” Additionally, the taste and smell of spirit energy lingers faintly on a man's body, and is comparatively thicker on the penis. Monsters can enjoy the taste by licking a man's body, or taking it in their mouth or vagina. For monsters, a man's very existence itself is like a sweat treat because he has spirit energy within his body that they can taste and enjoy by licking, sucking, and having sex, resulting in pleasure that soothes their body and heart.

For that reason, monsters say “Delicious.” or “Looks delicious.” when they see a human man, and they refer to sex as “eating”.

Since monsters build up demonic energy by obtaining spirit energy, monsters that have more sex with men and get more energy poured inside them generally become stronger individuals. The more powerful a monster becomes, the more spirit energy she requires, and they never get tired of consuming it. For monsters it's like a drug: the more they absorb, the more they want, so when more spirit energy is poured inside them, not only do they become more powerful, they grow into much more lustful monsters.

The spirit energy of each individual man has a distinctive feel and taste. Humans can't sense it, but monsters are sensitive to it, and because of that, it's possible for them to sense and distinguish the presence of individual men based on the trace amounts of spirit energy that a man scatters around.

Husband's Spirit Energy
The taste of spirit energy is greatly influenced by the state of the monster when she ingests it. When they have sex, the quality of spirit energy increases and the more powerful their love and desire for a man becomes. In other words, the spirit energy of the man they recognize as their “husband” is the highest quality spirit energy to a monster, and there is no better treat. Just having semen, which contains spirit energy, on the tip of their tongue will cause the scent of it to completely enrapture them, and if it is poured inside their womb, then they will be engulfed by the greatest happiness due to the sensation of being stained only by their husband and having their body and heart become full of their husband, along with the thick taste of their husband which they most prefer.

Once they taste their husband's spirit energy, not only does the energy of other men become unpalatable, it becomes so disgusting that it makes them feel like throwing up. Most monsters that have known the taste of their husband's spirit energy become a prisoner of that energy, practically entering a state of semen addiction. Once this happens, sex with monsters improves: they offer stickier oral service, sexual intercourse becomes more frenetic and lasts longer, and they avariciously covet even the spirit energy included in saliva, so kisses will change to become deeper and more lewd.

The odor they can sense from the faint spirit energy released by their husband also fans their arousal and makes them unbearably horny, so if they smell it directly, their body and heart will melt into a sticky mess, and make them unable to think about anything but tasting their husband's spirit energy.

For them, it's best to have semen which includes spirit energy poured into either their mouth or their womb, but having semen splatter on their body and having their body painted white with semen is never unpleasant to them. Even though they'd feel like it was a waste, having their whole body covered in their beloved husband's semen and its odor would allow them to sense their husband from all over their body and make them experience strong ecstasy whether they like it or not.

Once they're totally out of it, they will unconsciously scoop up the semen on their body with their fingers and carry it to their mouth, or spread it and rub it into their body even more to get the feeling and odor of the spirit energy to remain on their body. Humans can't sense it, but as for monsters, especially those smelling their husband's spirit energy, the thick, sweet scent strongly tickles their nostrils. Since it continues to linger for quite a while even after they wash it off, they can keep feeling happiness and joy from being indefinitely engulfed in the odor of their husband's energy.

Other Items Monsters Eat
spirit energy is the greatest treat for monsters, but there are many of them that mainly eat food other than spirit energy, and even monsters that mainly eat spirit energy can also replenish nutrients by eating normal food.

There are also monsters that prefer to eat the raw flesh of wild animals or wild grasses, but their sense of taste is basically extremely similar to that of humans. With a few exceptions, monsters can also eat cooked stuff made with ingredients that are edible for humans. Among the monsters, there are many that seize men and keep them at their side, and perhaps for that reason, monsters seem to instinctively know what humans eat, and many cook to feed men.

Since monsters can survive just by having sex with men, eating normal food is often for other reasons besides getting basic nourishment. Even among monsters that primarily feed on spirit energy, there are many that also taste and enjoy food purely for amusement. Also, since there are various foods with a variety of effects among the foods of the demon realm that improve sex with men such as fruits that boost monsters' charm and abilities, cause monsters to go into heat, or heighten sexual sensitivity, etc. there are many who periodically eat Prisoner Fruit as a dessert to enhance their own charm, and use the various ingredients of the demon realm to cook and eat “appetizers” which make sex with men more delicious. There are also monster chefs who specialize in such “appetizers”, and in the cities of the demon realm there are restaurants run by monster chefs that are said to be popular with monster and incubus couples.

Additionally, there are also nutritional supplements made using spirit energy collected by Golems. They're drugs for monsters that can't get a human man, and a tiny amount replenishes a huge amount of energy compared to normal food, but since this spirit energy that's not obtained through sex with men is bland and doesn't taste very good, it's basically not preferred. It tastes especially disgusting to monsters who have tasted their husband's spirit energy at least once as described before, and it's not something they can bring themselves to drink.

Furthermore, it seems the monsters of the “Age of the former demon lords” preferred to eat human flesh, but the monsters of the present have changed greatly, so they instinctively find the idea of killing and eating humans to be disgusting, and they wouldn't even consider it.

A Monster's Body
The monsters' forms range from being not much different from that of a human woman, to a variety of forms that are like a human woman mixed with anomalous parts, such as a woman with wings instead of arms, or a woman's upper body combined with a different lower body, etc. Although they have various forms, as for the part of them that has the form of a woman, it may be a beautiful, full-figured, voluptuous temptress, or it may be an adorably lovely little girl who stimulates a man's protective instinct and desire for dominance whether he likes it or not. Either way, they are all extremely attractive and ideal to men.

And it's not just the sight of them. If a man touches the faintly flushed soft skin that they show off even once, he'll be enthralled, and it'll make him want to hold them tight and keep touching that skin forever. The inhuman blue, green, etc. skins of some races are also alluringly beautiful, and they'll draw a man's eyes and imprison him with their devilish charm. Furthermore, even their body odor sweetly and pleasantly tickles a man's nostrils. A monster's female scent is peculiar and good, awakening the male instinct inside of men. It makes a man want to be engulfed in the smell forever.

Many monsters have extremely durable bodies and high physical abilities compared to humans. Some races have high athletic abilities and freakish strength, and they are easily capable of robbing the lives of untrained humans, but of course they never think of any such thing, and they hardly ever actually do it. To them, those athletic abilities and freakish strength are not for that purpose. Instead, they're mainly used for capturing men and having sex. Besides, their overflowing stamina is for having sex with a man again and again over a long period of time, and their strong legs and loins are for getting on top of a man and shaking their hips violently.

Additionally, a monster's body is specialized for having sex with men, and it is built to be sensitive to all of the pleasure that they can receive from a man. Even when men fuck them violently enough to break a human woman, they don't feel any pain, and all they can do is enjoy the strong pleasure. Even little races that are way smaller than humans, like the Fairy, only experience ecstasy and euphoria when their stomachs swell up as they get pierced by a man's rigid erection that is way bigger than even their own body. It is impossible for a monster's body to be broken through sex.

Reproductive Organs
A monster's body is generally equipped with the same kind of organs as a human woman. However, even though the monsters various organs look the same as human, they are equipped with greatly different functions and uses. For monsters, their basic life activity is having sex with men, so of course they're used for sex. It's not an exaggeration to say that their entire body is an organ for having sex with men.

Once their devilish vagina engulfs a penis, it tightens up as if to keep the prey from escaping, and begins pulsation to milk out semen as though it has a mind of its own. Through extreme pleasure, the inside of the man's head is stained one color with thoughts of them. Even after semen is released, in order to swallow up every last drop of it, the womb greedily holds in the beloved man's alter-ego and won't let it go. Once all semen is completely released, the pulsation will greedily start again right away to try and get more semen. Their vagina and uterus are equipped with the monster’s unique sensory organs for absorbing a man's spirit energy and tasting it. Pleasure and the taste of spirit energy spread throughout their whole body and they experience a sensation like their body is melting.

If semen is poured inside their womb, as long there is semen in their womb, the thick taste of spirit energy continues to linger. Until the semen in their womb disappears, their thoughts keep melting away with ecstasy and euphoric feelings. For that reason, they always want to taste sugary sweet spirit energy, and to that end, they'll demand sex from men again and again and even rape so they can keep the inside of their womb full of semen as much as possible. They like to spend time joined with men for the same reason. It's not just pleasure. They love the sensation of the taste of their beloved man continuously spreading throughout their entire body.

Of course their mouth is also used for eating, and it has adapted specifically for pleasuring men and milking semen. Besides the normal sense of taste, it is equipped with a monster’s unique special sense of taste that can sense the flavor of spirit energy included in a man's semen and saliva, etc. Also, inside their mouth, a slight amount of demonic energy is included in the faintly sweet saliva that is secreted. When they engulf a penis, lick, and suck it, it is used as lubricant to provide even more pleasure, and aside from that, it is sent directly into the man's body through kissing, hotly igniting his passion from within. Their tongue extends alluringly, crawling freely around the penis and giving pleasure as if it were a living creature. While kissing, their tongue deeply and wetly tangles around the man's tongue, greedily trying to taste saliva. While giving a man pleasure like this, if thick, sticky semen is eventually released inside their mouth, they can fully enjoy spirit energy due to the monster’s unique taste buds equipped everywhere throughout their mouth, such as the tongue, and mucous membranes, etc.

If they swallow it afterwards, the taste and aroma of spirit energy, which is the best and the sweetest, passes through the throat, and then at the same time as it drops into the stomach, a hot, satisfying sensation and a mind-numbing ecstasy courses throughout their entire body.

The monsters use more than just their mouth and vagina during sex with men. The monsters know all of a man's weak points. Their palms gently envelop the penis, and each finger tip deliberately attacks the man's weak points. The alluring monsters' hands give the penis pleasure by fondling, stroking, and enveloping it, guiding a man to climax.

Monsters with full breasts can insert the penis between them, and then while using their hands to freely change the shape of their soft breasts, they give the man a sweet, melty pleasure. In addition, the feet, tail, etc. will be used to give pleasure to a man, and monsters who have vines and tentacles as part of their body will also use those. There are some that even use their hair to pleasure men. In this way, as far as monsters are concerned, their entire body exists for having sex with men and milking semen. It's extremely pleasant when men feel pleasure from their body and release spirit energy into their body.

Also, as was explained in the section “sex with monsters”, these organs adapt to their husband once they get a husband and change into organs specialized for sharing pleasure with their husband. If it's a devoted monster, then she'll even feel that her entire body exists solely for her husband's sake, and she'll feel powerful joy because of it.

A Monster's Intelligence
The standard for monster intelligence varies widely depending on race, but nearly all monsters can understand and utter speech in the same way as humans, and it's possible for communication.

Although their standard intelligence varies, most races come equipped with an instinctive knowledge concerning sex with human men. Also, no matter how low a monster's intelligence may be, they will greedily study and memorize knowledge concerning sexual matters.

There are some monsters that have intelligence and knowledge that greatly surpasses humans, and there are even monsters who can devise various new spells, magical items, and medicines. However, no matter how smart they are and how much knowledge they've accumulated, they're still monsters, so of course that knowledge will mainly be used for having sex with men. The various spells and magical items they develop are mostly used for improving sex with men.

TEMP NOTE GIVE CATEGORY OWN PAGE
The monsters have durable bodies, high demonic energy inside their bodies, and even a strong resistance to disease. Also, although they appear similar to humans, they are different organisms, so most of them don't come down with the same kinds of illnesses as humans. However, there are some peculiar and dreadful illnesses that only afflict monsters. Let's introduce some of them below.

Mamono Realm Fever
Monsters normally release a minuscule amount of demonic energy from their bodies, but normally it's under control. When it goes out of control, a huge amount of demonic energy ends up being discharged as a powerful charm spell. The energy of those who contracted the disease that is released as a charm spell will unconsciously target their husband or a man they like if possible. If not, it will pour into any man who approaches, and drive him wild with a powerful lust for the afflicted. Afflicted monsters lose all strength because of a lack of demonic energy. Since they space out and feel feverish while they are afflicted with the illness, even a normally ferocious monster that enjoys raping men will find herself getting thoroughly raped by men driven wild. Additionally, in the middle of sex, spirit energy that is poured inside is immediately converted into demonic energy and continuously poured into the man, so the sex won't end until they both get completely worn out and fall asleep.

It's not an illness that can lead to death. If they rest for a while and get some sleep, they naturally recover. Also, after getting completely worn out after non-stop sex with a man exposed to demonic energy, if she sleeps a whole night while still joined with him, it's even possible to make a full recovery overnight because the demonic energy released by the afflicted goes through his body and returns to her own body, However, if treated through this method, the man who remained joined with the afflicted will definitely change into an incubus due to his body having been continually exposed to large amounts of demonic energy throughout the night.

Pneumania
(TL Note: Literal title translated as "spirit thirst disease".) An illness where the body and instinct of the afflicted feel that there is not enough, even though they do have plenty of spirit energy, causing them to constantly seek more. If monsters who have known the taste of spirit energy, especially the taste of their husband's energy, go a long time without having sex with a man or their husband, and don't absorb spirit energy, then outbreaks may rarely occur.

It's only clear that an outbreak has occurred when the afflicted has sex with a man. They tend to think that they just can't be satisfied since it's been so long since they had sex, but even after tons of sex, the afflicted won't be satisfied. They'll continue to desire spirit energy unlimitedly. No matter what kind of monster she is, once she's tasted spirit energy after an outbreak of this illness, her head will become filled with thoughts of nothing but spirit energy, and she'll become unable to think of anything else until the illness is remedied.

Additionally, since they actually get more than enough spirit energy each time they have sex, the body of the afflicted actually rapidly grows more lusty, and the more sex they have, the more wild the sex becomes. It's an extremely terrible illness.

The disease can be remedied by doing nothing but having sex all day long except while sleeping and repeating this over and over for a while. Since the afflicted convert every single bit of the huge amount of spirit energy poured into them during this time into demonic energy, after making a full recovery, their power as a monster is greatly increased compared to before the outbreak. Afterwards, sex will change, becoming more lewd and wild. Furthermore, the man who kept having sex with them during their treatment will have had to have sex a significant number of times in a short period of time, so he'll definitely change into an incubus during the treatment.

Alraune Pollen Allergy
Outbreaks rarely occur among monsters who breathe in pollen produced by Alraune. Since all of the alraune became females after the shift to the “new Demon Lord's era”, they no longer use pollen for reproduction, but even now, whenever spring comes, they release pollen infused with demonic energy into the air. The afflicted have the inside of their body violated by demonic energy after breathing it in, and then their body begins to naturally prepare for intercourse with a man. They end up in a state where their body flushes hotly, yearning for a man, the throbbing is intense, their vagina is always wet, and nectar drips out. The saliva, sweat, love juices, etc. of those afflicted with this illness have a sweet fragrance and taste, almost like alraune nectar. Men are lured in by the fragrance, and when they lick it, it melts away their thoughts.

There is no clear way to treat it. Some temporary relief can be had by having sex with a man, but both partners will get all sticky because the larger than normal amount of vaginal secretions causes a larger than normal amount of semen to be released. Furthermore, it is said that if a man afflicted with ordinary pollen allergy has sex with a person afflicted with alraune pollen allergy, a defensive mechanism kicks in, and the demonic energy infused in the alraune pollen seems to drive away the other pollen, so the man's normal pollen allergy will be cured.

For that reason, scholars expected the alraune pollen to have some kind of curative effect for pollen allergy, but if a man has sex with the afflicted and takes in alraune pollen even once, from then on, he'll become extremely sensitive to alraune pollen. In reaction to the fragrance of the sweet nectar and the slight amount of pollen, etc. released by the afflicted, he'll be overwhelmed by a maddening lust for them, his body will begin preparing for sex, and he won't be able to stand not having sex with them. For that reason, many scholars have expressed the opinion “isn't it simply being overwritten by a more severe form of pollen allergy?” instead of claiming that the original allergy was cured.

TEMP NOTE GIVE CATEGORY IT'S OWN PAGE
Most monsters prioritize their own pleasure and desire. They're hedonists who hate it when morals and ethics, etc. get in the way of pleasure. Also, the strongest desire of all monsters is to have sex with men and obtain mana. Their values and behavioral principles are based on that. Their thoughts and actions are in line with that, and when monsters have conversations, etc. the topics are often mainly focused around capturing and having sex with human men.

Monster Assault Against Humans
Basically, monsters that don't have a human man will think firstly about attacking and obtaining a man. Monsters tend to use whatever means necessary if it's for the sake of obtaining a man. Of course they'll assault and forcibly rape, but they may also use whatever means available such as seduction, spells, and potions to make a man their prisoner and claim him. Even if a man despises monsters, they'll rape and pleasure him again and again until the hatred directed at them changes into endless lust.

Monster Values
Monsters that have obtained a human man think firstly about having sex and act accordingly. For monsters it is common sense to prioritize having sex with the man they love more than anything else. As for their thoughts and actions, they're mainly focused around getting off harder with their man, and having more sex more intensely and frequently. Monsters that have obtained husbands are even more remarkable. A majority of their thoughts and actions are focused around their husband, or having sex with their husband. Of course having sex with their husband is usually their highest priority. Food and outfits, etc all start to be chosen based on reasons like “pleasing their husband more” or “making their husband even more aroused,“ etc. Monsters are already lascivious from the beginning, but the more sex they have with men, the more their values and behavioral principles become tainted by it.

Naturally with values like these, the monsters fundamentally have no sense of aversion to sexual matters. Of course they have no resistance to using their own body for sex with men, and if it's for the sake of furthering their enjoyment of sex, then they have no qualms about using aphrodisiacs or spells not just on the man, but on themselves as well.

Monsters' Relationship to Womanhood
The values of the monsters who have had their forms changed at the hand of the current Demon Lord are extremely close to those of the succubi, one of which is the Demon Lord herself. On top of that, they have been strongly influenced by the ideals of the Demon Lord. They conceive of the ideal monster as being so alluring and lascivious that it can be called the ideal succubus.

Lasciviousness is considered to be a virtue, and the more lascivious they are, and the more sex they have, the more highly regarded they are as monsters. A monster ought always give in to desire, have sex with men, and indulge in pleasure and spirit energy. The obscene form of a monster in ecstasy, drunk with pleasure, showered in spirit energy, and no longer concerned with anything but sex is the most beautiful and wonderful form of a monster. Among the monsters, there are some that are pure and chaste, and some that have a strong sense of shame. One could even say that they are very unlike monsters in general. And yet, they aren't even repudiated according to the monsters' values which regard lasciviousness as a virtue. The reason why is that for the monsters even that is just one of the tools they have to arouse men and get sex. It's because the monsters know that human men are attracted to and aroused by those kinds of women.

When monsters give off the smell and aura of spirit energy that can only be sniffed out by monsters, it means they have had that much sex, and had lots of spirit energy poured into them, so it's proof that they've spent their days indulging the way a monster should. Monsters that haven't gotten a man yet, or still haven't had that much sex yet get envious, saying “I wanna hurry up and do it a lot too.”

Even the current monsters respect and fear fighting skills and magic, etc., but they value seduction techniques for charming men, and sexual techniques for pleasing men, etc. just as much if not more. For that reason, monsters well-versed in sex are respected just for that, and the status of the succubus, which can even be called the symbol of sex, as well as that of other monsters like them, has risen greatly compared to in the age of the former demon lord.

Also, monsters have an ideal image of the kind of woman they want to be just as human women do. Eternal beauty is something that women, whether monster or human, have desired forever. The reason monsters try to stay beautiful forever is naturally so that they can continue to imprison a man forever. To them, dressing up is a way of accentuating their own attractiveness, causing men to grow fonder and more lustful towards them. On the contrary, if dressing up won't please a man, then it's entirely meaningless. To them, things such as dressing up “to be popular with the same sex,” or spending money freely on expensive accessories just to satisfy their own desire to show off the way that human women sometimes do is not very meaningful.

As far as monster women are concerned, women should be aggressive towards men when it comes to romance and sex. If a man won't turn and look at them, then they'll charm him with their body through assault and rape. They try to ignite a man's desire by being bolder and more aggressive when tempting men, and taking action on their own to seize a man's body and heart is the way a devilish woman should be. Although they are few in number, there are also races that are passive in nature who wait for men to assault them, but they spare no effort in making men want to assault them by pouring pheromones and demonic energy into the man, or adjusting their looks and charm to appeal to the man that they're targeting, etc. There are none among monster women that are truly passive towards men.

To monsters that have husbands, the ideal form of a wife is none other than the ideal form of a female. Keeping their husband prisoner eternally through their beauty and changing him into a male that desires nothing else but to have sex with them, then devouring his lust and spirit energy, and bearing his children, is for them, the greatest joy as a female.

Monsters' Relationship to Human Men
As has been thoroughly described in all the sections until now, the monsters need human men for everything, including feeding, reproducing, etc. They don't feel the same cold emotion towards humans that a predator feels towards its prey. They treat them just as if they were their own kind, or with even greater love and affection. To them, while human men are their “most delicious food,” at the same time, they are “male breeding partners,” and “dearly loved beings.” For the monsters, love is directly tied to and connected with lust. Once they fall in love with a man, at the same time their heart beat quickens, their body grows hot and flushes, and their womb throbs seeking the man.

We can say the opposite as well. For many monsters, love takes root during sex. Thinking “I'm after spirit energy, so anyone will do,” they have sex with men they've captured as prey, and then when they receive that spirit energy in their body, that hot desire and pleasure changes into love. A man who shouldn't have mattered often ends up becoming the one and only man for them. This is the reason why most of the men who get assaulted by monsters are never able to escape from their clutches. In this way, the love and desire monsters have for men consist of the following 3 desires: “appetite” “lust” “love”. All 3 desires end up being aimed at a beloved man at the same time. “I want to attack. I want to be attacked.” “I want to have sex.” “ I want to eat.” “ I want to have this male's children,” etc. Their infinite desire and love are unleashed upon the man using their devilish body during sex. That's why monsters are so lascivious and lustful that human women don't compare.

The deepness of their love is revealed through having repeated intercourse with a man. The way they express love is different depending on various races. Some of them don't refer to their most beloved man as husband at all. There are even races that call them “slave”, “servant,” “food”, etc., but the fact that they keep a particular man at home and have sex with the same man again and again is itself proof of the strong love they have for the man. It can also be seen from their attitudes, and the way they treat the men. Even monsters that milk spirit energy from a man every day as “food”, don't just milk the men who are supposedly “food” violently. They seek syrupy sweet “food.” They're overjoyed when their “food” gets off, and they have deep love just like other monster couples.

Even those that give their man obscene training every day as a “slave” and repeatedly rape them would hate it if their “slave” died or suffered. Just like the other monster couples, all of them value their “slaves” even more than they value themselves. It's just that for them, love takes on a different form. The monsters bodies and hearts will have already completely changed, becoming exclusive to their “food” or “slave”, etc. The strong love and desire they direct towards their man is not at all different from that which would be directed at a husband. For them, their “food” or “slave”, etc. is irreplaceable in the same way as a husband.

Of course, the monsters have various different preferences for men, and there is such a thing as an ideal man to them, but there are hardly any types of men that they hate. Though they may feel that a handsome man is cool, or cute, it's not in their values to despise an ugly man as ugly. This even extends to virility during sex, which is normally very important to them. It's “wonderful” if a man has a huge tool and is well-versed in sexual techniques, but even if a man is timid and has a small tool, they just think “cute” or “I'll train him.” It is impossible to be excluded from the monsters' interest due to personal appearance or physical performance. Tales of ugly male bandits and thieves, etc. who were charmed after being attacked by monsters due to sheer pleasure and love and then had a change of heart and stopped attacking people are not uncommon. The only ones really hated by them are complete scum who are beyond redemption.

Monsters are extremely positive towards human lust. Lust for women tends to be despised as a filthy thing among human women, but to the monsters, a man's lust is never a filthy thing. Rather, they view such lustfulness favorably, and feel great joy when it is directed at themselves.

The kind of man that becomes a prisoner of pleasure, gets highly aroused as soon as he is tempted, and eagerly anticipates being raped makes them feel that he is “cute.” The kind of man who, ruled by desire, directs his lust towards them and attacks like a beast is regarded as “wonderful” by them. To them, when a man directs his lust at them in the same way that they direct their lust at him, that is proof that they're desired by the man. Lusting for one another and seeking one another is proof of love to them. Even supposing a man is a pervert with peculiar sexual propensities, in general, no matter how perverse the act, they'd be thrilled and overjoyed to have carnal desire directed at them. The depravity of it would only serve to accelerate the joy of pleasure.

Also, just like with male lust, they never hate the male sex organ from which spirit energy and desire is born and unleashed upon them. To the monsters, everything about it is wonderful including the shape, which could be called grotesque, the feint scent of semen that lingers, and the heat that can be felt from an erection. It makes them envision penetration and ejaculation, and then all their thoughts melt away, igniting instinct. And if it belongs to a man they love, they'll be so fond of it that they'll spontaneously rub their cheeks against it.

Cheating often happens with human couples, but once the monsters get husbands, they never cheat. It is said that they're in half disbelief when they hear about how some human women think nothing of infidelity. The love and lust they have for their husbands isn't just born from emotion; it's deeply engraved in their instinct. No matter how far apart they are from their husband, they can't think about wanting any other man, and even if another man tries to tempt them, they display no interest. On top of that, even if a man were to forcibly rape them, their body will have already changed to belong to their husband alone, so they can't experience physical pleasure from any other man. Their body and heart will never yearn for a man other than their husband, and they never want the spirit energy of someone other than their husband, so it's impossible for their love and desire for their husband to waver.

To a monster with a husband, their husband is the only male in the world that exists, so to them they don't have any other choice to begin with. In the case of human women, they sometimes cheat because they get lonely, but in the case of monsters, if their husband won't come be with them and they get lonely, they'll just assault him themselves in order to get a good taste of their one and only male, and fill in the feeling of emptiness that comes from loneliness with his cock.

It has been mentioned a countless number of times until now, but monsters love human men more than anything. For that reason, they can't stand the loss of beloved human life. For that reason, unless it's for self defense, or protecting their friends or husbands, they won't take the lives of human men or women. Even when humans attack them, they basically try to avoid taking their lives as much as possible while fighting. If they don't have husbands, they'll capture and claim men for themselves. If they already do, then they'll try to capture and take men prisoner for other monsters. The main reason they fight humans is to claim men who are captured during the fighting. For that reason, when the monsters clash with the soldiers of the Order, casualties are extremely few, but the captured soldiers become the prisoners of the monsters without exception, and they end up getting dragged into devilishness.

Until now, I've mainly written only about human men but, the monsters are fundamentally affectionate even towards human women. They won't take their lives lightly. Concerning this, it is highly involved with monsterization which is described later, so I'll describe it in detail in that section.

TEMP NOTE GIVE CATEGORY OWN PAGE
Monsterization is the phenomenon where humans and other races change into monsters by having mamono mana inside their body. It's mostly human women that become victims of monsterization, although there are a few exceptions. Regardless of race, it is purported that monsterization can basically only occur in females. In the section after this, we'll be explaining how human women change into monsters, but the orientation and magnitude of the changes to the body and mind vary depending on each individual and what monster race they are changing into. We would like you to bear in mind that, as with “monster ecology”, the commentary presented from here on is just a general explanation of the average monsterization phenomenon, and transformation.

The Process of Transforming Into a Monster
Monsterization occurs when demonic energy gets inside the body of a woman. The most typical way for this to happen is by infusion of demonic energy through sexual intercourse, as done by the Succubus, etc., but there are various other processes through which demonic energy could invade a woman's body and change her into a monster.

Women who have had demonic energy poured into them will have the mana within their body discharged as if driven out by the other energy. Otherwise, their energy will be converted into demonic energy, as if it were being swallowed by the demonic energy.

Whatever the case, monsterization is completed at the same time as they completely lose their energy, and a woman will end up being reborn as a monster. When demonic energy gets inside a woman's body, it causes her body to flush, and dimly dulls her thoughts. This ensures that she can't resist the temptation and pleasure from a monster, and makes it so that she will receive an even larger amount of demonic energy. The more the body becomes brimming full of demonic energy, in proportion, the closer her mind and body approach that of a monster.

Demonic energy changes the body into a monster-like, sensitive one that can greedily receive pleasure. Even the kind of pleasure that monsters enjoy regularly is far too strong and intense for humans, and it would shake them. Pleasure like an electrical shock would paralyze them to the degree that it would even immobilize their mind and body, staining them completely in the color of pleasure. In the same way, the more the body becomes filled with demonic energy, the more changes appear. If energy flows out of the body as demonic energy is poured in, so too does everything that gets in the way of receiving pleasure such as inhibitions, reason, self-restraint, and repugnance for monsters and pleasure, etc. It probably feels as if the heart has become lighter. Once the heart loses everything excessive, before long, it is filled with “a good feeling” that makes a monster's desire to seek and enjoy pleasure sprout. If spirit energy starts to change into demonic energy, at the same time, human values and thoughts are painted over by devilish pleasure, and one can understand that she's changing along with a sense of pleasure and depravity. For humans, the sensation of demonic energy swelling within their body and mana changing into demonic energy is accompanied by an extremely sweet feeling.

Just before completely changing into a monster, one can sense that she's being enveloped by thick demonic energy, and having her body filled by it is felt as a wonderful thing. And then, due to monsterization, the body will begin to transform and what they are likely to feel when parts that they lacked as a human start growing from their body is intense pleasure, and a strong feeling of liberation. Upon experiencing this sweet sensation, even their tears that had at first come from fear, sadness, and despair change into tears of joy for having become a monster by the time they transform.

Even in the case when one escapes before completely becoming a monster, the demonic energy that entered the body usually never disappears. If it's an extremely miniscule amount, then it will disappear after a while, but if the amount is larger, then it's often too late even for those who haven't yet turned into a monster. Demonic energy remaining in the body continues to alter the body and mind from within. Once the body has tasted the sweet sensation of demonic energy flowing inside, one is unable to forget the decadent pleasure of a monster, and her body will burn hotly. Her mind will be troubled by obscene thoughts and images, and the erotic dreams she'll be having every night, and desire will grow. Eventually she'll become unable to bear it, and she'll descend to a monster on her own seeking the pleasure of a monster, and to transform into a monster.

Furthermore, spirit energy is the vital energy possessed by humans. In other words, it could also be called “human magical energy”. Of course the kind of women referred to as heroes and great sorceresses also possess lots of this energy. When they have their body violated by demonic energy and are monsterized, this vast amount of spirit energy is converted into demonic energy, so the more powerful someone was as a human, the more powerful and lascivious the individual will become as a monster as well.

Those Who Have Changed Into Monsters
When human women change into monsters, big changes appear in both their body and mind. Basically, their values and thoughts from when they were human disappear, and change into the monster thoughts and values, but they're different from those of monsters that were born a monster. There are also sensations they can feel and values they possess especially because they were originally human. Let's focus on that point, and explain what sorts of changes happen to them.

The Body After Transforming Into a Monster
The appearance of women who has become a monster changes hugely. Their appearance is altered based on their appearance from when they were human. Their face becomes devilishly beautiful or cute to the degree that eyes of men are always drawn to them. The body changes into a charming body that inspires carnal desire in men. While their appeal is different depending on the race and the individual, with everything from mature adult women, slender, beautiful girls, and little girls with decadently soft skin, every monster has an appearance that looks beautiful or cute to a typical human man. It's the same for those who change from human to monster. No matter who the woman, once they change into a monster they will change into a beautiful and lovely form for tempting men.

Furthermore, the change is always based on their face from when they were human, and in most cases, the changes occur along the lines of accentuating the attractiveness of the original, so, for example, even if there are huge changes, it's not like they change into a completely different person. It always ends up so that they bear a strong resemblance to the original woman.

As for additional huge changes, the color of the skin will change to match the characteristic of the monster's race, and the organs and parts characteristic of the race will appear. Beast ears and tails, demon horns and wings, etc. will grow, and depending on the race, the lower body may also change into a grotesque form.

Compared to humans, monsters have extremely tough bodies and high physical abilities. Also, since monsters mostly don't catch the kind of diseases that humans catch, even if their body was weak as a human, or they were afflicted with an illness, they mostly become healthy due to monsterization. To those who had lived in a human body up to that point, with a monster's body, it is likely to feel like they're in a good condition and capable of doing anything. Compared to when they used to be human, their body feels lighter as if freed from bindings, whereas before, on the contrary, it used to feel heavy.

Also, to those who were born as monsters, it's just normal, so it's a hard to understand the feeling, but according to those who used to be human, compared to when it was a human body, a monster's body, which always actively seeks men, feels as if it's engulfed in a sensation of warmth and exaltation.

After a while, the body feels hot, and blood rushes to their head, and then they'll seek to have sex for the first time after becoming a monster, and they'll attack a human man. Also, the way to use their body is engraved in their instinct, so they can probably move freely and use it right after becoming a monster. Naturally, as soon as they change into a monster, the methods of how to attack men, milk spirit energy and use their body are imprinted in their instinct, so right after changing into a monster they can actively attack men and enjoy spirit energy and pleasure.

A monster's lewd body is extremely sensitive compared to that of a human woman so that they can actively receive pleasure. If one has sex with that body, the amount of pleasure received is many times greater than the pleasure that can be obtained by having sex with a human body. In the case of human women, the pleasure is so powerful that their mind cannot process it and they'd pass out, but in the case of monsters, their level of tolerance for pleasure is in another league, so they can enjoy that sort of pleasure and indulge in it. The devilish pleasure experienced by those who have sex with a man for the first time after changing from a human to a monster makes them reconfirm how wonderful it is that they've changed into a monster and they are a monster. It's enough to make them think “I can't go back to being human anymore,” or “I don't want go back to being human.” Once this happens, they become a prisoner of the lewd body they obtained by becoming a monster, and the pleasure of using it, and in monster-like fashion, they just keep becoming even more lascivious than those who were monsters to begin with.

The Mind After Transforming Into a Monster
As with the body, the changes caused by becoming a monster have a huge impact on a woman's mind. Those former-humans who became monsters don't feel fear or despair from having changed into a monster or changed into a grotesque form. Even if they experience despair until just before or right after the transformation, it will disappear in an instant. If one transforms into a monster, she'll literally be engulfed in a feeling of liberation and ecstatic joy as if she has been reborn. The joy of having obtained a devilish body that can bewilder men and make them drown in it, magnify the pleasure of sex by many times, and enjoy and indulge in it. And then, arousal and the anticipation of using and enjoying that body plenty from then on washes away despair and such.

As for women who become monsters, the disgust and resistance towards sex that they had when they were human disappears, and a monster-like thirst for pleasure and spirit energy wells up. Moreover, so that they can indulge in it, they are released from the inhibition and restraints, etc. that were troublesome when they were human. The heart will feel lighter, almost like being in a dream, enveloped by a fluffy, happy feeling. And then, as if to trade places, the affection for human men necessary for satisfying the thirst for spirit energy and pleasure will overflow endlessly. By becoming a monster, they become able to sense the odor of men's spirit energy, and the obscene desire that men direct towards them. And then, they end up recognizing them as wonderful things.

Due to this, they realize that men are delicious-looking, cute, and very wonderful things that will satisfy their own desires. If they become like this, then afterward, they'll already be ruled by a monster-like desire to assault and have sex with men. No matter how prudish they were and how much they hated men to begin with, they'll end up strongly wanting and loving men. Additionally, upon changing into a monster, if there's a man they want, then they'll just give into desire and seek him. Upon realizing that they themselves are equipped with the body, beauty, and ability to imprison a man and make him their own, their heart will be overflowing with self-confidence and hope.

The desire for men that's taken root in them, and this self-confidence, will make them arrive at such thoughts as “If a man hates and fears me, then I'll just thoroughly ravish him and make him my very own prisoner,” “If my feelings are unrequited, then I'll just thoroughly gratify him and make it so that he can no longer live without me,” and will cause them to attack men without hesitation.

And then, once they know the pleasure of sex with men and the taste of spirit energy, to someone who lived as a human until that point, it's something that feels like the most wonderful happiness they've ever felt in their entire life. It's said to be so much so that they'll even come to regret their human past, thinking something like “Why didn't I realize all this time that there was something that felt this good, something that was this delicious, and that becoming a monster was something so wonderful?” After that, as if trying to make up for the period when they were human and unaware of such pleasure, they'll become engrossed and keep having sex, and they'll end up continuing to indulge in pleasure as if to verify the happiness of becoming a monster and getting what they want.

Also, as with the body, their personality and memories from when they were human will end up largely remaining intact. As with the body, the changes brought about by monsterization will mostly accentuate the appeal of their original personality. At a glance, it might seem as if their personality hasn't changed at all from before, but monsters always acquire a monster-like, lustful personality without exception, and their thoughts are disposed to end up being hedonistic.

For example, a shy village girl who was afraid of men will retain her looks that spur a man's desire to protect, and modest personality, but she'll start to actively tempt a man, deliciously suck and lick a penis in her mouth, straddle a man's lower body, and furiously ravish him. A diligent female knight that never missed a day of practice and gave off an air of nobility will retain her diligence, and she'll mount a man's body every single day and perform sex. Her normally noble attitude and appearance would be retained, but she would become pleased to receive a man's desire to tarnish her noble figure with his body.

Among them, there are some changes to personality that match the race, and certain flaws and feelings of inferiority that a person used to have will change to become erased, etc. so there are also those whose personalities change greatly, but on the other hand, there are also those who used to pretend to be something they were not when they were human, so when their true personality comes to the surface, it looks like their personality changed. However, even in such cases, the original personality is never lost entirely, and each individual's essence doesn't change. There's always a part that remains which makes one feel a “resemblance” to the original individual from before they became a monster.

Moreover, personality changes such as these appear in a monster-like direction to ensure that they feel fondness and desire towards men, and depravity, etc. Additionally, by changing into a monster, a sadist who enjoys inflicting wounds on others and making them suffer will change into a sadist who enjoys forcibly raping others and pleasuring them willingly or unwillingly. In monster-like fashion, they'll change to have a sense of disgust towards killing humans. Due to these changes, there are probably also those whose personalities appear to improve by becoming a monster.

Concerning a person's memories from when they were human, they're basically carried over unchanged even after becoming a monster. Sometimes memories that the person herself desires to forget become fainter, but omitting some exceptions, memories are almost never modified.

A person's feelings and affection towards people, of course, remain intact. On the contrary, by becoming a monster, the very incarnation of love and desire, the love swells up enormously inside them. Feelings towards a man that one possessed as a human will end up blossoming by becoming a monster, for instance if there was a man that they had a strong love for such as a boyfriend, husband, or lover, etc. then the lascivious desire directed towards him swells up. A monster's instinct will recognize him as her husband, and after becoming a monster, the body and mind will start to change to belong exclusively to their husband even before they have sex.

For that reason, a woman who had just become a monster that we would normally expect to have such a powerful urge for sex that she would just push over anyone and have sex with them without caring would actually become able to sensitively detect her husband's spirit energy, and pursue the hints of his presence, and she would head straight to him without even glancing at other men.

Why Transformation At All?
Monsters basically have an instinct to attack human men, but some among them have an instinct to attack women to increase their allies, and there are some who just try to attack women on a whim. Before we get into the reasons, first we'll explain how monsters think of human women.

Presently, the Mamono Lord has an ambition to unify them into one race, with humans as males, and monsters as females. For that reason, as far as monsters are concerned, human women are beings that are destined to subsequently become the same race as them. As with human men, they approach them with affection, and don't like hurting or killing them for no reason.

Also, when they see human women unable to fulfill their desires, and bearing it patiently when their desires are inhibited by human rationality or human society, etc., monsters feel sorry for them. When a monster sees the way many adherents of the Order have disgust for sex and pleasure, and try to distance themselves from it, it makes her think it’s a waste: “How could she not know something that feels so good?”

When the monsters that live happily amid pleasure see a woman like that, they unconsciously end up feeling like teaching the woman about the joy of sex. Monsters that have converted human females into their own race in this way have fun and enjoy watching the uninhibited appearances of those they personally changed into monsters such as the sight of a woman who used to be troubled by being unable to fulfill her desires pushing down her loved one and imprisoning him using her own power, or the sight of a little girl that had never known pleasure until then, drowning in pleasure, falling and becoming lascivious, etc.

In this way, surprisingly, the reason monsters change human females into monsters is mostly to meddle, or just for amusement.

Also, women who changed from human to monster have a more remarkable tendency to do so. They're extremely aggressive about changing human women into monsters. They know the joy of changing from a human to a monster, something that those born as monsters have never tasted. Additionally, since they have memories and feelings from when they used to be human, they compare their current life to their old one, and they think life as a monster, indulging in pleasure and spirit energy, and spending one's time making love with a man, is extremely wonderful. To them, the wonderful world that they now live in that's full of desire and the odor of men's spirit energy inspires them as a female, but compared to it, the world when they used to be human will likely be regarded as extremely hollow. For that reason, they want to share pleasure and happiness with human women, and they think that women should abandon their humanity as soon as possible and join them on this side. In order to free them from the shackles of humanity, and guide them to the paradise known as monsterhood, they aggressively attempt to change human females into monsters.

Also, in addition to such thoughts, there are those among the monsters who regard human women as incomplete beings, who don't even adhere to the monster’s principles of faithfulness and are unable to imprison and rule men through pleasure. There are even those who believe all women should become monsters, and they aggressively try to convert human women into monsters whenever they find them. Monsters with these kinds of beliefs are called “radicals”.

Incubization
An incubus is mainly a human man that kept receiving mamono mana, and containing it within his body, resulting in a transformation into a being that's convenient for monsters, possessing superhuman stamina and lust. Under the current concept, monsters are all female beings that only possess mamono mana, so an incubus, which is male, and possesses both mana and mamono mana at the same time, is not a monster. Ultimately, they're just humans altered by mamono mana. However, the Order regards them as being the same as monsters, and they're targeted for expulsion and suppression.

Transformation Into an Incubus
Compared to monsterization, in which changes suddenly appear, changes caused by incubization are extremely gradual. Unlike a woman's monsterization, where they totally change into a monster both mentally and physically after having sex one time, the changes that occur when a man transforms into an incubus and afterward, appear bit by bit each time he has sex with a monster.

Human men transform into an incubus by having sex with monsters, and having demonic energy poured inside of them. Unlike women, who recover spirit energy by absorbing it from the air, men continue to produce spirit energy within their own body, so compared to women, it's more difficult for demonic energy to take hold, and they do not change into an incubus just from having sex once.

In the case of the succubus family of monsters, they possess “succubus' energy” which has a higher retention rate, and causes men to release more spirit energy in a single session of sex by infusing them with it, so compared to other monsters, incubization is extremely fast, and in the case of a powerful succubus, it's even possible to change a man into an incubus by having sex once.

Also, even if it's a monster of another race, after spending a long time as their husband, and living beside them, by continuing to have sex, demonic energy gradually takes hold in the body after each time, and eventually, a man will transform into an incubus.

Additionally, even monsters not of the succubus family can accelerate the incubization process by continuing to ravish a man with multiple monsters, and aside from that, there is “succubus' secret elixir”, a medicine made from succubus' energy, and there are special rituals and spells that can be used to quickly change a man into an incubus.

When transformation into an incubus occurs, it's not like one can clearly tell that he's transformed, as was the case when a woman is monsterized. In the case of monsterization, a woman is able to grasp that she's become a monster because of the changes in her body, and a feeling of ecstasy like she's been reborn, but in the case of incubization, before one knows it, he's already changed into an incubus.

In the course of getting continuously violated by monsters over and over, a man who at first would tire soon, exhaust his spirit energy, and pass out, will steadily increase the amount of time he can have sex, and the number of times he can release spirit energy increases. In the beginning, the pleasure is so violent that one can't even think straight, but one gradually becomes able to enjoy the pleasure. Gradually one will change so that he can't help but consider having sex with the monster in front of him, and gradually, he'll come to desire to be ravished by the monster before his eyes. In this way, bit by bit, one will change into an incubus without being aware of it.

What makes an incubus an incubus, and a man a man is the spirit energy within his body and the existence of a spirit energy production faculty. Very rarely among the incubi, there exist those who unconsciously destroy their own spirit energy production faculty. In that case, spirit energy will not be produced, and the body of an incubus who loses spirit energy and is completely ruled by demonic energy will completely change into a monster. This monster is called an Alp. The process of changing into this monster is described in the sex change case file.

Mental and Physical Changes Caused by Incubization
As for changes caused by incubization, the changes that appear basically make it convenient for the monster that one is coupled with.

First, it is purported that the looks almost don't change at all compared to when one was human. Monsters don't care very much about the attractiveness of a man's face, so in most cases there are no changes whatsoever. The body changes to become more healthy and durable so that it's convenient for sex, but it's rare for the appearance to change greatly other than that.

A rare exception occurs and the appearance greatly changes in the case of those who are too feeble or fat, and their form will be vastly improved so that it's convenient to have sex with monsters. Also, in the case of those who are so old that it's a hindrance to sex, they will also be rejuvenated.

After one has changed into an incubus, the mind also changes so that one's values become nearer to those of the monsters, but compared to monsterization, even if only a little bit, human-like values from the period when one was a human will remain. However, the values and thoughts of an incubus, a being that became a monster's prisoner so much so that it altered the nature of his mind and body, will change to become eager to have sex with monsters. One's lust will swell up like that of the monsters, and disgust towards monsters and sex, etc. will have long since disappeared, and one will change so that he aggressively desires sex with monsters.

Also, after being completely charmed by a monster, one's aesthetic sense will have changed so that he feels that the grotesque parts and organs of monsters are beautiful. Other than that, one's sense of time, and values concerning work and recreation will also change so that it becomes more convenient to live with monsters.

The biggest changes of all occur in the functions that are also most important to monsters that get used during sex. It depends on the race and preferences of the monster that one is coupled with, but most men who become an incubus will have their penis grow larger by leaps and bounds, and they'll be able to please monsters even more. The amount of semen and spirit energy released from there will be incomparable to when they were human, and they'll have boundless stamina so that they're able to release it again and again without getting exhausted.

The quality of the spirit energy is also remarkably different. It becomes so much thicker, stickier, and sweeter, that it's incomparable to when they were human, and one lick will make a monster melt. Also, human men sometimes lose the mood after expelling spirit energy, but it doesn't occur in an incubus, and their lust for monsters just flares up.

In addition to the normal food that they ate when they were human, it's also possible for an incubus to feed on demonic energy by having sex with monsters. For that reason, an incubus never gets exhausted when having sex with a monster. Instead, their entire body will brim full of lust and energy due to demonic energy. When the body of an incubus obtains demonic energy by having sex with a monster, it will immediately produce spirit energy. When this spirit energy is released to a monster, the monster will produce demonic energy from it and pour it into the body of the incubus.

Astonishingly, with this cycle, not only does the total amount of magical energy not decrease, instead it continues to increase, so it's possible for a monster and an incubus to keep having sex almost forever, and as long as there's one incubus and one monster, it's possible for them to live by just having sex. As far as the divinities and the Order are concerned, this nearly perpetual cycle is something that is in violation of divine providence that will greatly throw off the laws of the universe, and is extremely viewed as a problem.

Also, it's said that the lifespan of men who become an incubus becomes dramatically longer. Since they can keep living by having sex with each other, their lifespan is roughly the same as the monster that they're coupled with. Just like monsters, their appearance stops aging at a certain stage. It could be as a boy, as a young man, or as a mature man. Since an incubus is a being that's convenient for a monster, they change depending on the tastes of the monster that they're paired with. In this way, an incubus is none other than an ideal male to a female monster.

The power of an incubus grows stronger the more demonic energy they accumulate. In the case of those that periodically have sex with multiple monsters, it piles up, so in the case of a single incubus that makes a harem of multiple monsters and keeps having sex with them, it ends up causing the birth of an extremely powerful incubus. Regardless of how many monsters are in the harem, an incubus has limitless stamina and lust, and can have sex with all of them. Even if an incubus keeps having sex with them day and night alternatively for a period of several days, he'll never get tired, lose his erection, or feel pain or boredom. On the contrary, he'll end up being unable to get satisfied unless he has sex with all of the monsters in the harem, and it'll even get to the point where it's as if spending several days having sex with all the monsters in the harem is like having sex one time to him.

Additionally, those who become an incubus can also adapt to the environment to match the monster that they're coupled with. For example, an incubus coupled with a monster that lives in a desert, or near a volcanic crater, will gain resistance to heat, and an incubus that is coupled with a monster from a snowy country will gain resistance to cold. They gain such strong resistance that they can even actively have sex with monsters in such environments. To provide a remarkable example, due to a ritual performed by a Sea Bishop, there are incubi that became able to live underwater. This ritual is performed to quickly change someone into an incubus, so as a result of having been changed into an incubus with the demonic energy of the monsters of the sea, they've adapted to live underwater.

Since an incubus retains the demonic energy of the monster he's coupled with inside his body, a human woman who has sex with an incubus will end up transforming into that race. However, the lust of an incubus who's kept having sex with monsters will not be satisfied by having sex with anyone other than a monster.

Also, an incubus' superhuman lust is only directed towards the monster he's coupled with no matter what, and they don't have an instinct to attack the opposite sex like monsters do. For that reason, incubi do not attack and forcibly rape human women, and such an incident has never been confirmed.

A Kenkou-Approved Explanation of Monsterization/Corruption in MGE
The following is a KC-endorsed explanation as to how corruption and monsterization is actually meant to be understood in the MGE franchise:

Firstly, KC says that life after monsterization can be "However you want it, as long as it does not go against the spirit of MGE". Love conquers all and even without anything but love, you can still live. MGE is such escapist porn fantasy. It is not a work meant to make you suffer and in the end, everything will be settled at a good conclusion, as long as the setting permits it. And it is the main theme of MGE. From their first transformation, monsterization may make women lustful or loyal to their desire [TL Note: Assume this refers to their 'sexual desires'.], strengthening their instincts as Monsters, but it hardly changes the personality of the target.

Some may want to continue living a life where they can work, indulge in hobbies, explore cultures, go traveling/exploring, and partake in other various activities after the monsterization process. To this, MGE says yes. (This aspect can be seen in a handful of examples in the books. Following KC's original intentions, the priority of sex in their life will become nearly equal to that of having to eat a meal.) Some may choose to be completely free of life's duties and spend their remaining days indulging in sexual pleasures. To this, MGE also says yes. (This is a rare case, but can be quite an attractive choice for people who live in a country where working for 600 hours a month and dying of exhaustion is a real possibility.)

Some may feel a desire to release their violent urges and commit crimes like murder, theft, and other harmful acts. To this, MGE says no, definitely not. (In these people, Monsters will make the criminal indulge in their bodies so that their violent thoughts are overcome with love and lust. The priority shift of sex in their life is mostly intended to function in this way. It's not too different from any other case where a person's values are changed because of an experience they had. For example, our values/desires change when we eat a delicious dish for the first time [TL Note: I believe what he meant was that when you eat a new dish and find out you really like that taste, you're going to try have it again because it changed your desire for that particular food.]. And when we marry with a partner, the priorities of your life will definitely change.) So you'll still be free to live a 'normal' life after becoming a Monster or joining with a female monster but, sex will simply become a more raised priority in your life. This should still be acceptable for most be, right?

Additionally, we Japanese value the contexts of sentences more than what is written literally. We refer to this as called "言葉の綾 (kotoba no aya)". For example, if MGE says, "Men who have sex with Monsters begin to think of nothing but sex with them." the intention of the sentence was to describe how attractive the idea of having sex with Monsters has become. It doesn't mean that all of them LITERALLY become unable to think except for sex with Monsters.(But, if they really do want to think of nothing but sex with Monsters, then they are allowed to do that.) This seems to be one of the gaps in understanding that KC attempted to explain years ago. ''[TL Note: Back when MGE was becoming popular among Western audiences, there was a lot of confusion about things like the above. KC attempted to better explain the details to his Western fans but the endeavor ultimately ended in failure on both sides (This lead to some bitterness between KC and his Western fans but things have since returned to a more friendly state). As a result, the 'gaps' in comprehension of the story have continued to grow among Western followers as more and more information is posted without a proper explanation. The effects of these 'gaps' are very obvious among Western communities as almost all of them are plagued with constant bickering and arguments that don't have a clear answer. These disagreements have resulted in several other events happening among the Western audience but we'll save that for another time.]''

Most Japanese fans understand KC's original intentions well, and understand that MGE is an ideal world that rejects all "bad endings" regardless of how they might happen. Of course, there are people who dislike MGE because they think of it as a dystopian world but usually people don't continue to hang around the stories and communities that they dislike, seeing as how that would be a complete waste of their time. Lastly, about 'corruption' elements within MGE: Originally, 'corruption' was a fetish that focused on brainwashing, mind breaking, netorare, etc. KC appreciates some elements of 'corruption' like changes in physical appearance and the adoption of a more seductive and (sexually) aggressive mindset, but dislikes the 'bad endings' that usually accompany these things. If he was a true disciple of the 'corruption' fetish, then the Fallen Maidens would massacre people cheerfully, physically hurt you, and have sex with the person who brainwashed them while forcing you to watch. Of course KC did not want this so he chose to remove brainwashing and soften the strength of the 'corruption' fetish within MGE.

Now, 'corrupted' girls focus on the feelings of desire and true love that they previously suppressed and their personalities are liberated rather than warped against their will. (Though, it should be noted they that do undergo mental changes when they go through monsterization like becoming much more lustful and having a greater sex drive. If MGE's detractors would call this brainwashing and hate it, then it can't be helped. [TL Note: By saying "it can't be helped" he means that that if people claim this is brainwashing and choose to hate it then let them hate it. As we'd say here in America, Fuck'em]).

Wilmarina is a special case. Not only her but all the other Fallen Maidens were described by KC as girls who couldn't be redeemed without giving up their humanity. She (Wilmarina) was bound by sense of duty to become an 'ideal hero' and as a result, felt guilty when she couldn't fit the role. She compensated by obsessively helping others and never taking a moment to enjoy some time for herself. This led to her being manipulated and used by people but after being turned into a Monster, she is free to follow her true nature. In this case, I think it's actually the Holy Church and her (Wilmaria) father that did the brainwashing. She had spent her entire life sacrificing every waking moment to helping others so to call her selfish for indulging in her true desires seems to be a mistake.
