Monster Girl Encyclopedia World Guide I: Fallen Maidens

Monster Girl Encyclopedia World Guide I: Fallen Maidens is a collection of character bios about several women in the Monster Girl Encyclopedia (MGE) universe.

Plot
Each character bio gives a brief account of that particular character's story (background, history, etc.) before showing the character as having been transformed from a human into a mamono by a lilim, a rare type of succubus and a daughter of the Demon Lord.

One point of interest is that in each character bio, it is stated that there is a certain man in each of the character's lives, whom the have a close history with. After becoming mamono, each and every one of the characters has their way with that man.

Also, available translations have shown that the character bios indicate "you" (the reader) are the man that they are involved with, likely as a form of reader interaction. Furthermore, there is evidence that the male whom each of the characters has fallen for is actually the same person in every story, adding to the likelihood that the reader is the designated male in each story.

Lescatie
Religious Nation “Lescatie”

A religious nation that no longer currently exists because it was dropped into the demon realm at the hands of the lilim Deruella. Before it fell, the king “Castor Bistoa Lescatie” made the faith of the chief god the main religion. The order was extremely powerful, and basically all of the nation's important offices were filled by individuals from the upper echelon of the order. It was an enormous nation which boasted the second most powerful military among all order aligned states at the time. What's more important than it's size and population is the fact that it was the number one hero producing nation in the world.

There was an extremely substantial number of organizations and facilities that raised people from childhood into disciples to fight for the order, and many heroes who received god's divine protection appeared. For that reason, the religious nation of Lescatie was the hope of humanity and the order, and an extremely large threat to the monsters; however, the light of hope was extinguished in the blink of an eye due to Deruella's invasion. It is said that there was a lot of dissent amongst the people to begin with because the nation was managed by the upper echelon of the order for the order's conveniences.

In contrast with the dazzling central district, there were many slums where people suffered under heavy taxation, and besides that, many of the heroes who mostly lived in the central district, especially young heroes, didn't think highly of the government that ignored their will and tried to manipulate their lives. The hearts of the most important force, the heroes, were not with the religious nation of Lescatie, and more and more of them went over to Deruella's side. We could say that this is the reason for the nation's defeat. The religious nation of Lescatie was formerly a symbol of glory to the order, but it's presently a huge disgrace because of how quickly it fell, and the failure to recapture it.

Demon Realm Nation "Lescatie"

A former religious nation that was dropped into the demon realm by the lilim Deruella. The queen " Francisca Mistel Lescatie" rules, but she is infatuated with Deruella who changed her into a monster, so she's a puppet and Druella holds the true authority. The left over hero-raising facilities and churches were mainly converted into pleasure quarters for the entertainment of monsters and incubi. Compared to other demon realms, these many facilities are distinguished as being even more radically obscene.

The entire nation was converted into a Demon Realm, and it is filled with extremely thick demonic energy. It's always dusky, and demonic energy shines eerily. It has become a country that is extremely easy for monsters to live in. The demonic energy gets thicker as one approaches the central district, and once inside the castle, it is so thick that it causes the monsters to become sexually excited and lose themselves. Additionally, in the middle of the castle in the throne room there are several monsters of enormous power including "Wilmarina" who continuously have sex with one man, and highly thick demonic energy is always being produced. It is the space where it is most concentrated.

If an ordinary human enters, it is so potent that they will change into a monster just from being showered in the demonic energy. "Amanomiya Koyoi" who was introduced in the first book did well to endure it. Additionally, it has worsened since Koyoi became an inari. Also, to the delight of the monsters who live in Lescatie, a mass of this highly condensed demonic energy is released into the city on holidays by Koyoi, who excels at controlling demonic energy. This mass of demonic energy drops in appropriate areas throughout the city depending on Koyoi's whim.

For a while, the area around where it was dropped becomes overflowing with highly thick demonic energy. A narcotic effect is induced that ignites the passion of monsters and incubi, making them feel the best. Having sex with their partners in this state amplifies the pleasure and arousal they would normally experience by many orders of magnitude. The demonic energy lingers for several days and during this time their arousal never subsides and their bodies never grow tired. They continuously feel amazing and experience the greatest pleasure. For monsters who desire to spend their days indulging in pleasure with their husband, it's probably the happiest holiday ever. It is said that when the holidays come around, the monsters of Lescatie anticipate having these presents dropped where they live, and everyone starts getting restless.

Foreword
“Monsters drown humans in supernatural pleasure and tempt them into an existence of a devilish nature just like themselves. The monsters I found living in “Demon Realm Nation Lescatie” when I dropped by this time were beings that truly fit that description.

In this book, I've summed up everything I've collected until now as a scholar of monsters and added the knowledge I gained due to the cooperation of the mistress of Lescatie, and a daughter of the demon lord, the lilim Druella, and many “former” humans. I've written in detail about the ecology and moral values of the monsters in “Monsters' Ecology”, and recorded the transformations that human women undergo when changing into monsters in “Monsterization Case Files.”

I would like the readers to read the second section carefully and become more acquainted with the details concerning the monsters. That is, if you still don't want to surrender your humanity.”

- a certain wandering scholar of monsters

“There is no suffering or sadness here. All there is is a wonderful world of indulging in love and pleasure to the heart's content. If you come this way, you'll never have to fear anything, and you'll never have to suffer.

This book is a guide to help you cast aside human fetters and be reborn.

Now, let's have fun together...♥ I'll teach you about the wonderful world of monsters...♥”

Monster Transformation
'''(Pg 77-79) incubus

Incubus

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.

1. Until Changing 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 mamono mana poured inside of them. Unlike women, who recover mana by absorbing it from the air, men continue to produce mana within their own body, so compared to women, it's more difficult for mamono mana 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 mana 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, mamono mana 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 mana, and pass out, will steadily increase the amount of time he can have sex, and the number of times he can release mana 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 mana within his body and the existence of a mana production faculty. Very rarely among the incubi, there exist those who unconsciously destroy their own mana production faculty. In that case, mana will not be produced, and the body of an incubus who loses mana and is completely ruled by mamono mana will completely change into a monster. This monster is called an “Alp (encyclopedia – p. 108). The process of changing into this monster is described on p.92 of this book.

2. 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 mana 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 mana 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 mana, 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 mamono mana 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 mamono mana. When the body of an incubus obtains mamono mana by having sex with a monster, it will immediately produce mana. When this mana is released to a monster, the monster will produce mamono mana 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 mamono mana 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 (encyclopedia I – p. 116)”, 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 mamono mana of the monsters of the sea, they've adapted to live underwater.

Since an incubus retains the mamono mana 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.

(Pg 81) CASE 01: Sexual Intercourse

["Ahh... it's so nice to be a demon... ♥

Being one with the one you want, becoming beautiful,

feeling good, having a superb body... Ahh, it's like a dream ♥"]

(Formerly a Human Village Girl/A Succubus)

Many monsters can change human women into monsters themselves. Through the act of sexual intercourse, they change these women into monsters by pouring their Demonic Essence into them. This is the most common, and efficient, way for "Monsterization" to occur.

During the close contact of sexual intercourse, monsters will stay glued to a woman pouring their Demonic Essence into her. Also, this contact will fill a human woman's mind with pure pleasure, making it harder to resist the influx of Demonic Essence and smoothing the process of conversion.

During this sex, with a monster, the human woman will change into a lewd monster herself, their bodies completely stained with pleasure, their appetite for sex developing and they're taught about the lewd abilities of a monster. These women also learn that despite these sweetness of their current pleasure they will feel even more pleasure and excitement when they have the company of a man.

These human monster are given a thorough sexual education and there are many who feel a great gratitude and respect for the monster that changed them into a monster themselves. With the sweet pleasure, good feelings and new monstrous body given to them by their "Big Sister", a name many call the monsters that transformed them, they will find a human man before dawn and have their "Big Sister" watch them use their new perverted skills.

The most iconic monster known for using this method is the Succubus. For the hedonistic Succubi the process is almost as enjoyable as intercourse with a man and as such it is a relatively common practice. The human women targeted for transformation into a monster are given the greatest sexual pleasure possible, reaching climax dozens of times during the sexual intercourse. As these women are given pleasure, the Demonic Essence flooding into the becomes them becomes greater the more they climax. Also, during this sexual intercourse, they are taught to enjoy their own sexual preferences.

Giving the women are becoming Succubi the greatest amount of pleasure is also extremely pleasurable for the Succubi themselves and is one of their greatest drives. The women turned, who may have once thought such a body was disgusting or filthy, now think that pleasure is a great thing. However, even when creating Succubi, no matter if it is day or night, they will still seek pleasure from a man if they spot one.

(Pg 84) CASE 02: Spirit Energy Corrosion

["Haa... Haa...my body's getting hot... ♥ hey...can you help me... ♥"]

(Female adventurer lost in the Demon Realm/Human)

Spirit energy (or mana), floating free in the atmosphere, will slowly flow into a human woman's body, accumulate, and eventually, once enough has built up,change her into a monster. Thanks to the phenomenon of the Demon Realm constantly releasing, and being and being steeped in monstrous demonic energy, any women who visit a Demon Realm for a period of time will become a Succubus.

Unlike being assaulted by a monster, exposure to mana is a slow, gradual process. A woman who is exposed to mana will find herself becoming more and more excited as the mana trickles into her, eventually her thoughts fading as she enters an oestrus. Her body heating up little by little and becoming feverish, she'll also take a special interest in any companions with her as her body becomes more sensitive to pleasure.

Once the woman has entered oestrus, her body feverish with desire, it is already too late for the woman, in this state she is already on the verge of becoming a monster. Spotting a man she will attack him and when he releases his spiritual energy, this will provide the final burst needed to completely change her into a monster.

During this phase, the effected women, their body feverish and minds foggy, find it impossible to resist these feelings and it is inevitable they will change into a monster when they become across man. Having just transformed, their bodies will seethe with fever and lust, thanks to this they will continue to force themselves on the man that just helped them transform.

For those traveling in the Demon Realm, particularly heroes sent to slay the Demon Lord, this constant corruption caused by the monstrous mana flooding the atmosphere is a big problem. Even though you can avoid or fight off monsters, there is nothing that can be done to prevent this corruption from occurring.

So far only two female heroes, a two member party, managed to reach Demon Lord herself, they were, however, already on the verge of becoming Succubi and were given their lastpush by the Demon Lord's own hand. So far no hero or heroine has managed for the face off against the Demon Lord without becoming a Succubus or Incubus and joining her ranks.

In addition, the type of Demonic Essence that a human woman is exposed to can change the species of monster she'll become, different areas producing different types of mana. For example, a woman who drowns at sea is invaded by Poseidon's mana changing the woman into a Nereid.

(Pg 85) CASE 03: External Wounds How is it? The wound gouged out by my fangs? How is it? The wound torn by my claws? They're hotly throbbing, right? Soon you'll be at ease..... Because soon, you too will become a beast. (The last words a female soldier of the Order heard just before changing into a werewolf.)

Monsterization can occur due to a variety of reasons, and there's also the danger of a human woman changing into a monster as a result of a wound sustained from a monster attack. External wounds caused by claws and fangs infused with a werewolf's mana (encyclopedia I – p. 26) cause mana to pour out of the body instead of blood. And after mana pours out, their mamono mana will be poured in. In a woman's case, she will be changed into a werewolf the same as them. No pain is felt from such wounds. Instead of hurting, the wound heats up and continually throbs. The hot throbbing of the wound gradually spreads throughout the body. The heat of the wound causes the body to flush, and the throbbing of the wound causes the body to throb, remaking a woman's body into that of a monster. Basically, the wound completely heals at the same time a woman changes into a monster, but by that time, their monster body will be seeking a man and their monster womb will begin to throb with even more heat, seeking sperm.

Mamono realm weapons made using “mamono realm silver”, a special metal produced exclusively in the mamono realm, and special weapons made from hardened mamono mana have the same effects as the claws and fangs of werewolves as described above. They can inflict wounds not on the body of a living thing, but on a living thing's “mana”. Due to these sorts of weapons, once a large external wound is sustained, mana pours out, and the mamono mana contained in the weapon flows in, causing women to change into monsters such as “succubi”, etc. These weapons were produced especially because of the monsters' disdain for injuring and killing humans. They are widely distributed and used by monsters such as those in the Mamono Lord's army. They are actively being used even in battles with the Order's troops. They're changing the soldiers of the Order into monsters like themselves instead of corpses. Battles between humans and monsters end with extremely few dead and injured for the human side thanks in large part to the existence of these weapons.

Furthermore, the effectiveness of mamono realm weapons varies greatly depending on the quality of the weapon used as a catalyst, the quality of the mamono mana infused, and the skill of the one wielding it. In the case of a weapon where all those qualities are low, even if a woman is cut and some wounds are inflicted, it won't result in monsterization. However, on the contrary, if all the standards are high, such as in the case of a “Dullahan (encyclopedia I – p.170)” master fencer wielding a sword made by a “Cyclops (encyclopedia I – p.110)” artisan with the concentrated mana of a lilim, then even a scratch can result in monsterization. A wielder of such a weapon leaves a mountain of monsters in heat in her wake rather than a mountain of corpses.

(Pg 86) CASE 04: Parasism

["Aha♥ an egg went inside.....♥ My baby,

she is bouncing with joy inside your womb...♥

Ufufu, hurry up and be born so we can get off together...♥"]

( A maid working at Lescatie Castle / Roper)

Even among the numerous varieties of monsterization, this “parasitism” is something extremely peculiar. “Matango“ come from human women parasitically infected by mushrooms. “Roper“ come from human women implanted with eggs and parasitically infected. Other than those, it is said that there are also slimes, etc. that are parasitic in women. Unlike other monsters which change women into monsters by infusing them with demonic energy, they implant things such as eggs and spores, etc. inside women, and make them grow inside women's bodies. By doing this, the women's bodies are remade from the inside, and changed into monsters.

The sensation of having the body physically remade from within is far greater than that which is caused by demonic energy. Having their whole body teased all over, kneaded around, and changed into something else is accompanied by extreme pleasure. Reason gets thrown out the window and their minds will be stained one color with pleasure. In the case of monsterization due to parasitism like this, even after changing into a monster, their human values and thoughts continue to linger for some time.

The parasite that infects her makes the host's body become unbearably hot and gives her extreme pleasure. By robbing her thoughts and implanting its own thoughts, it rules its host by seizing control of the woman's thoughts. The parasite's objective is a source of nutrition, and the obtainment of a human male partner for the production of seeds. The parasite can read which man she yearns for from the host's memories and feelings, and it will target that man, or target any man indiscriminately if there is no such person. The parasite will lead the host to a man by manipulating her thoughts and actions and will try to obtain the man using the host's body.

Eventually the parasite will make the host have sex with a man, and absorb spirit energy. Upon obtaining spirit energy, the parasite begins rapid growth, binding itself with the host in an attempt to become one. After perfectly binding and fusing with the host in this way, the parasite will stop controlling the host, and will return all the thoughts that it had seized back to the host. However, after fusing with the parasite, the host will no longer have human-like thoughts or values. Her body and heart will have changed into those which belong to a lewd monster. The host's self-perception will also change. Until that point, she would have thought of herself as “a human parasitically infected with a monster”, but due to fusion with the parasite, she would start to think, “I, myself, am a monster.”

Since the parasite's instinct and memories are also completely fused, even though she'll have the memories of being manipulated as a host, she'll also have the memories of doing the manipulation as the parasite at the same time. Ecstatic two-fold joy springs forth, since she was reborn as a host, and she obtained her own body as a parasite. Their thoughts and behavior objectives become based on the parasite's instinct. That objective is mainly to keep having sex with their beloved and obtaining spirit energy which is a source of nutrition. And then, they'll implant their own egg or spore, etc. inside a human woman and change her into their own kind.

This is the troublesome thing about them. Unlike other races that change human women into monsters for amusement or to be meddlesome, attacking human women and changing them into monsters is their main objective. Since it's the equivalent of becoming pregnant for other monsters, they strongly desire it, and since they do it aggressively following sex with a man, if one of them appears, it will cause a widespread outbreak in no time at all. Villages, towns, and in the worst case scenario, entire nations of matango and roper will be formed.

(Pg 87) CASE 05: Fusion

["Hey~ Hey~!♥ Get sticky with me!♥ There... Put it inside my sticky pussy...♥

I want you to shoot lots and lots of sticky semen♥".]

(Former human, assassin of the religious kingdom of Lescatie/Dark Slime)

It is unique even among the multitude of monsterization phenomena. As of the present, only "Dark Slime" uses this method. They envelop human women with their own half-liquid body, and in doing so, tease the woman's entire body, diving into and violating every single orifice. The messy body of the slime continually gives them sticky pleasure throughout their entire body that we can say is truly out of this world, melting away the woman's thoughts. As for women violated by dark slimes, everything melts into the dark slime, including their body, thoughts, knowledge, and memories. All of it mixes with the pleasure given to them by the dark slime, and their mind gets muddled.

After the woman's consciousness has been completely melted away by pleasure, before long, even her body melts away inside the dark slime and disappears. After the human body melts away and disappears, a “slime core” the same as one of those possessed by the slimes remains. After that, the woman's body is reformed from half-liquid goo based on her form from when she was human. In this way, after one's heart and body have completely melted away, a new “dark slime” is born.

Unlike other slimes, dark slimes are a race that possesses high intelligence and thinking abilities. For that reason, their knowledge and intelligence from when they were human remains intact, but since the inside of their head has been melted by pleasure, they think of everything based on sex and pleasure, and they use everything for that purpose. If they were originally a powerful sorceress, all of their spells will be used to heighten their enjoyment of sex with men. If they were originally military strategists gifted with great intelligence, they can come up with an elaborate strategy to imprison whatever man they have their mind set on.

(Pg 88) CASE 06: Undead

[“Uh... ah ah... I'm so cold... big brother...

Hey... Fill my empty insides with it...♥

Fill my insides full of your white stuff...♥“]

(Former human, younger sister who died during her first year as a soldier of the order / zombie )

Demonic energy sometimes even dwells in the corpses of human women, resurrecting them as monsters. Monsters born in this way are called “undead”, there are many races, including “zombie“ and “ghost”. Corpses in lands such as the demon realm that are full of demonic energy will most certainly resurrect as the undead, but aside from that, there are also many who are intentionally infused with demonic energy and resurrected directly by monsters. Also, since it's in the nature of demonic energy to bind with powerful human emotions, it easily gathers in the corpses of those women who died with strong regrets, and those who left behind a man they deeply loved, so even in lands where there is little demonic energy, undead outbreaks are not uncommon.

No matter how horrific their wounds were at the time of death, the bodies of the undead are mended enough to be attractive to men. Rotting also stops, and they don't reek. The undead basically keep their memories from when they were human intact, but many of them have diminished intelligence and capacity for thought due to a lack of spirit energy. They'll try to assault human men and have their way with them due to an attachment to life and an attachment to sex. All of the undead are fueled by the spirit energy of human men, and through it they maintain their body.

At first they are dim-witted, and hardly seem to be alive, but the more they have sex with a human man, the more they regain their beauty and wits from when they were alive. Not only that, as far as beauty is concerned, since they've become monsters, by continuously having sex, they grow even more alluringly attractive than they ever were as humans.

It is hypothesized that the monsters seek humans because of 3 desires, “appetite” “lust” and “love”. In addition, the undead have a fourth strong desire. It is an “attachment to life.” They sense life when they cling to a beloved man and feel the warmth of his body, when they join with him, have sex with him, and are pierced by his cock, and when spirit energy is poured into their body. They are always continuously seeking to have as sex with a man, the only thing that makes them feel alive. Most of them would rather not separate from a conjoined state with their beloved if at all possible.

Furthermore, as mentioned previously, by continuously gaining spirit energy, the bodies of the undead are mended to the state they were in before death. An undead that is continuously pumped full of tons of spirit energy everyday can even completely mend her own womb, if she so desires, and then it's even possible for her to become pregnant with the children of her beloved. For an undead, the sense of life she gets at the moment of conception is the greatest happiness she can ever know as an organism, and as a monster female. During pregnancy, at the moment of the child's birth, and even afterwards, this joy will always remain with her. The children born on such occasions are not human children. If it's a zombie, then the child will be the same kind of zombie. For this reason, it is said that the undead aren't “human corpses reanimated via demonic energy”, but “organisms called undead that are reborn from human corpses due to demonic energy.”

(Pg 89) CASE 07: Corruption Oh, God... I confess. I didn't use my body, even though I wanted this person. I didn't strike him with my desire. My sin was being ignorant of such a pleasurable thing...

Ah... You came again for me, huh...

From now on..... I swear to you and God, that I'll drown in this pleasure, and be lewdly corrupted......

Aah… Please fill me with more thick white stuff and stain my sin pure white... (A sister / dark priest and former human confessing while straddling a man.)

Yielding to pleasure, losing to desire, and doing whatever one pleases is nothing other than corruption to the humans who uphold the teachings of the Chief God and regard chastity and abstinence as righteous.

The one who governs such “corruption” is a god of the monsters possessing vast power that is called “the Fallen God”. She regards falling, and living according to pleasure and desire as virtuous, and she uses her own subordinates, angels, and devotees to corrupt every race, whether human, monster, or other. Her religion is propagated by her angels and devotees using sex to directly instill the body with the wonderfulness of corruption and spending ones days enjoying hedonism. They basically increase the number of devotees using mostly this method, but sometimes the Fallen God directly calls out to a human heart in an attempt to corrupt it.

Among people who are devotees of the Chief God, there are those who can hear the voice of god, and use god's power to cast holy spells. Such is only possible because the devotee is connected to god through mana. Due to this connection, the will of god can be revealed, and it's possible to use divine powers. This mana link is extremely firm, but if the devotee begins to harbor doubts about god and the Order, their faith weakens, and they're corrupted by mamono mana and in the process of changing into a monster, then the link weakens tremendously. According to one explanation, the mana of the Fallen God has a very similar quality to that of the Chief God, so she can usurp these weakened mana links, and use them to call out to human hearts. The Fallen God's words are words of temptation that vividly illustrate the ecstasy and happiness that awaits after falling.

Those who listen are painted with desire, and envision a wonderfully splendid future in which they do as they want, seeking sex, becoming more and more lewd and lascivious, ultimately falling as a filthy, depraved being that exists solely for the purpose of indulging in desire. The vision of the future revealed by the Fallen God is so sweet that their faith in the Chief God is completely swapped for faith in the Fallen God. Lewd desire and sex which were formerly taboo become deeply rooted for them, and conversely, overcoming desire and living abstemiously becomes their new taboo. On the contrary, they become ashamed of themselves for having formerly been clean and pure, and having had puritanical thoughts, so they have sex with men and try to fall as hard as they can, almost as if to drag down and defile their past self, painting over her with thick white mana.

Even in the case of monsterization where the devotees of the Fallen God are not involved, due to the intervention of the Fallen God's voice, one who would change into a “succubus” would instead change into a “dark priest”, and in the case of other races, as soon as they change, they awaken to the faith of the Fallen God at the same time that they change.

Human beings are animals filled with desire in the first place. The Fallen God awakens them to the desire that they possessed all along and corrupts them by making it swell so huge that desire itself becomes a core value. However, warping the values of god's servants who regard chastity and abstinence as virtuous to be exactly the opposite is something that feels almost like brainwashing.

(Pg 90) CASE 08: Ritual Aah...... thank you..... I too have a beautiful snake body, the same as god..... I'm so happy. I can bind my beloved man with this body, and continue to be joined with him...... (Former human, girl who was a member of the snake god faith / echidna)

Races that can change human women into monsters had that ability to begin with. However, they aren't necessarily the only ones that can change human women into monsters. Although it can take some time, there are various spells and magical rituals for changing humans into monsters that exist in the world.

One of them is the “ritual of the snake god” performed by the snake god faith. The snake god faith is one of the monster faiths where the monster “echidna” is worshiped as a god. It's treated as heresy by the Order of the Chief God. To them, the snake is the symbol of bountiful harvest, eternity, and womanhood. We can say that the form of lamia family monsters having a snake body binding men, and the motherly nature of echidna, the mother of monsters, are truly symbols of eternity and womanhood.

Also, they are symbolic of “power”, since they can seize the prey they desire, claim it as their own, and bind it to themselves. Not only echidna, but other lamia family monsters such as “medusa” and “lamia” also generally end up as targets of worship as relatives of god. The worshipers have peculiar values. Their children are also raised with those values from generation to generation. Along with their god echidna, they hold monsters in an entirely positive light. They desire the power to bind what they want to themselves the way that monsters, especially lamia family monsters can. Human girls brought up that way since early childhood strongly desire to become monsters themselves and acquire a beautiful, alluring snake body. Becoming an echidna means becoming a god themselves. Becoming another lamia family monster is also an act of approaching godhood. The ritual for converting such girls into monsters is the “ritual of the snake god”. The ritual is performed using numerous snakes.

By continuously exposing the snakes to the mamono mana of echidna and other lamia family monsters over a prolonged period of time, they can infuse them with mamono mana for future use. The ritual is performed over a special magic square that changes the body to make it easier to receive mamono mana and pleasure. The snakes infused with mamono mana are released onto the girl's body, crawling around, coiling around, and binding her while giving her pleasure. The mamono mana settles in over night. At the same time when the girl's body changes into that of a monster, in the case that she changes into a medusa or echidna, the snakes used in the ritual join with the girl's body, becoming her hair snakes. Once the ritual is over, the girls are ecstatic that their body has changed into a beautiful snake body like that of a god. They will then immediately desire to use that body to bind the man they love to them eternally.

As for the preparation of this ritual, when young men are offered up as sacrifices, in exchange, the lamia family monsters will continuously have sex with them, and after this the mamono mana produced from all that sex is then infused into the snakes. The higher the rank of the lamia family monster, the longer it takes for the preparation. If they're snakes for lower rank lamia, then it can be done in a few days at the earliest, but in order to produce a high rank echidna, it takes at least several years, and could take decades, depending on the case. That's why these girls feel extremely happy and honored to be chosen for the snake god's ritual, and even more so if they're able to change into an echidna.

One point about these rituals that deserves special mention is that these rituals weren't created by the monsters. They were created by humans who desired to become gods. In this way, among the adherents of the monster faiths, there are many trials for the sake of approaching godhood. Various spells and rituals for monsterization were produced by the hands of humans.

(Pg 91) Case 09: Possession Huh!? Why can't I take off this armor!? Damn! Damn! Oh, my head came off..... (Dullahan that had been a human knight until only a moment ago.)

In the dungeons where monsters lurk, there sleep various treasures such as valuable, beautiful ornaments, and magically enchanted armors and robes, etc. Even among such treasures, there exists some equipment such as clothing, weapons, and ornaments, etc. that is imbued with powerfully concentrated mamono mana.

This equipment is also called “cursed equipment” by humans. Once a human puts it on, they're unable to take it off, and the thick, solidified mamono mana dwelling within the equipment will flow into the human wearer's body to bind with the mana inside. At first, effects such as a heightened mood, and greater physical abilities, appear. Depending on what race the imbued mana belongs to, it can cause various other effects such as improved agility and a better sense of smell in the case of “werewolf mana”, freakish strength in the case of “ogre mana”, and the ability to cast ice magic in the case of “yuki onna mana”. However, if worn for a long time, with each use of the equipment's ability, more mamono mana flows inside. It's difficult to notice because there will be no change in appearance whatsoever, but bit by bit their thoughts and behavior will get closer and closer to that of a monster of that race. Additionally, like a monster, they'll start to feel that human men are delicious, and notice the sweet smell of mana in the air.

By the time they notice, it's already too late, and they're unable to remove the equipment. Their desire for men just keeps on swelling, and all they can do is wait until they change into a monster. Eventually, all of the equipment's mana flows into the wearer, and at that moment, the body suddenly starts changing completely into a monster. Equipment like this has been set up as a trap for humans by the monsters of the “radical faction”. Monster merchants disguised as humans sell them to people, and they get mixed in with the regular merchandise, so they're scattered throughout all the lands of the world.

These items are made with a special product of the mamono realm called “mamono realm silver”, a metal that is easily infused with mamono mana. Other than that, if items related to each particular race are used, such as collars for “werewolves”, armor for “dullahans”, or flower decorations for “alraune”, then it's easier to infuse mana. What's dangerous are pajamas made from “weresheep” wool, etc. Only a faint amount of mamono mana dwells in wool that has just been sheared normally, and it would have no influence on humans other than causing the original effect of peaceful sleep, but it's impossible to tell if there's one with condensed mamono mana mixed just by looking. If a woman were to wear it and go to sleep, then upon awakening, she would completely change into a weresheep.

Additionally, if a man were to wear one of these items, then he would gradually change into an incubus due to the mamono mana imbued in the item. In that scenario, what's different from changing into an incubus normally is that the mana generated by the man will change to be more preferred by monsters of the same race as the monster whose mana is imbued in the equipment. For example, in the case of equipment imbued with “werewolf” mana, the flavor and taste of the man's mana will change to suit the preference of werewolves. The scent would tickle the nose of werewolves and be more appealing to them compared to that of normal mana. No matter where the wearer went, he would be hunted by unmarried werewolves, and he'd end up getting attacked over and over.

(Pg 96-97) Monsterization Case File: Non-Human Monsterization

Monsterization of Non-humans

It's not just humans that change into monsters. Mamono mana can change all kinds of races into monsters, and, at times, even gods and material objects. In this section, let's introduce that sort of monsterization of “non-humans” just a little bit.

1. Elves

A type of people that live deep in the forests and build peculiar villages. They're also called “forest elves.” They are a pure and proud race, but they are hard-headed and stubborn. They are ascetic, and extremely negative towards sex and pleasure. They regard humans, monsters, and all things related to sex and pleasure as filthy and inferior, and they despise them. Since they have high magical energy, it's much more difficult for mamono mana to bind to them compared to humans, and monsterization is extremely gradual. They won't completely become monsters just from having sex with monsters. Mamono mana arouses their bodies, eventually leading to a state where they have lewd desires and fantasies. Then, upon receiving a man's sperm, they completely change into monsters. Elves are sensitive to magical energy, and at the stage when one has been corrupted by mamono mana, everyone around will notice it, and banish them from the village, so chain monsterization and conversion of elven men into incubi rarely ever happens.

After monsterization is completely finished, they become extremely lustful and lewd monsters almost like a backlash or something from everything until that point. When humans who think of sex and pleasure as dirty things change into monsters, in most cases, that hatred disappears, and they start to recognize it as a wonderful thing. But for most elves, sex and pleasure remain as filthy things along with humans. However, in monster-like fashion, they start to deeply love those filthy humans. As if ashamed of how clean they had been until then, they wish to be defiled with filthy lust and milky white semen, falling to become a being just as filthy as their beloved men. For them, it is an unbearably joyous thing. Just as they were once proud of their purity, it is said they become proud of their filthy, indulgent lives as monster “elves.”

Additionally, there is a matter that is often misunderstood. That is, even if “elves” change into monsters, they don't become “dark elves.” These two races were entirely separate from the beginning.

2. Fairies

A race that have extremely tiny bodies, and they are not monsters to begin with. They're a childish race that likes fun things. They spend every day playing and having fun. Since they are balls of magical energy, they are easily influenced by mamono mana. By playing with monsters that are childish like themselves, they get showered with mamono mana, and soon change into monsters. After becoming monsters, they still have the same childish appearance and still love to play, but in monster-fashion, they end up mainly choosing human men as their playmates. And then, after being taught by their monster friends, or by their own monster instinct, they'll try out very pleasurable forms of play.

They have tiny little bodies that look way too small for a man's penis to fit inside, but with a monster's durable body; they can swell up their stomach and receive a man's penis. It looks painful, but the fairies don't feel any pain. Even when they play in this state by having a man seize their tiny body and shove his cock in and out wildly, for them, the only thing induced by it is wild pleasure. Many fairies live in the Fairy Kingdom ruled by the Fairy Queen. The Fairy Queen and fairies want to have more fun and experience more pleasure. Many monsters are accepted in the Fairy Kingdom, and the fairies are changing into monsters one after another. In the not too distant future, the Fairy Kingdom will become a mamono realm, and the fairies will all become a type of monster.

3. Angels

Lesser divinities that are merciful and abstemious servants of the gods. Since they have extremely strong magical energy, they don't completely become monsters right away. Many of them retain the same sense of self, and when mamono mana induces lust and makes them do dirty things with human men, they just think of it as being part of an angel's duty to give happiness to people. In the same way that the Mamono Lord is connected to the monsters through mamono mana, the angels are connected to the Chief God through magical energy, and it is possible for angels to hear the voice of god.

However, in the case where they become self-aware of their affection for human men, that magical link is usurped by the “Fallen God,” and their indecent desire for human men is made to swell. Once a man lusts for them, it is said they end up being reborn as “fallen angels,” servants of the Fallen God who just want to fall together as ever more indulgent, lewd beings.

4. Gods

Mamono mana can corrupt even a god at times. “Poseidon, God of the Sea” and the “Fallen God” are gods that became monsters, and using their vast power, they have created mamono realms in other dimensions, changing the environment itself to make an ideal world appropriate for monsters to live in. If even more of the gods end up falling, the Mamono Lord's ideal world will be realized, and then the arrival of the end of the gods will be rapidly hastened.

5. Beasts

It is extremely rare for a mere beast to change into a monster. They will never change into monsters just from simply being showered with mamono mana. However, mamono mana reacts to love and lust, and it is extremely easy for it to become fused with those. For that reason, in the case of dogs and cats, etc. that are kept by humans and share a strong bond with their masters, a beast may change into a monster. Those who are called “kettoshii” and “kuushii” may have a humanoid appearance, but their forms are entirely covered in fur. Compared to other beastman type monsters, their appearance and biology are closer to that of beasts. From the time when they were merely beasts, they had a love for their master strong enough to change themselves into beasts, and a bestial desire to mate as male and female. They want more than anything to mate with their beloved master and bear his children.

6. Material Objects

Since material objects are inorganic, it is easy for mamono mana to dwell within them, especially things that were designed as receptacles for mamono mana, and human-shaped things. If there are more thoughts concentrated on an object, it becomes easier for mamono mana to dwell within it. “Golems” and “gargoyles,” etc. are also such with life within them. The magical material type monsters are almost entirely fueled by the mana of human men. They maintain their bodies through sex with human men.

Also, in Zipangu, spirits of things used and taken care of for a long time that have feelings of gratitude, or conversely, spirits of things that were abused and discarded that have feelings of resentment may manifest as “artifact spirits” and start moving. These result when the strong emotion dwelling within objects is fused with mamono mana, causing them to change into monsters. As for artifact spirits, in either case, their goal is “to be used” by humans. Of course they can be used as ordinary tools, but after becoming monsters, they all obtain a devilish body without exception, and a bigger goal for them is to get human men to use their body and get off with them.

In this way, various other living things besides humans may change into monsters. However, when they change into monsters, their race is fixed. If they're elves, then they change into “elf” monsters. If they're fairies, then they change into “fairy” monsters. Basically even when an elf is bitten by a werewolf, they of course still change into “elves.” Unlike humans, they individually have strong magical energy within them, so that's one of the reasons why, but the reason why only humans can change forms into various monsters might also be because the current monsters have become closer to “human” than anything else so that they can couple with human men.

(Pg 127) AfterWord

Well, I safely finished writing this time as well. While I was staying here in “Lescatie” writing, I was also attacked by many monsters, but my traveling companion, a Leanan Sidhe, held them off for me, so I somehow managed to avoid trouble.

Currently, the only reason human forces and monster forces are almost evenly matched in the struggle is because of the present state of affairs with monsters generally prioritizing having sex with men above all else, and only monsterizing women if they feel like it. If “radicals” increase like the monsters living in this country, and the monsters begin aggressive invasions, mankind could face a dilemma.

Well, I was originally supposed to be headed for Zipangu, what can I say, it seems I've become a wanted man, as expected. Somehow, I managed to slip through the Order's pursuers and take refuge here in Lescatie. I guess this time for sure I'll head for Zipangu. I may end up writing another volume after being chased somewhere else by the Order. As long as my life is safe, we'll meet again with the monsters in another book.
