Codex Of Monster Girls

Section D: Devil

Mid-rank demons that give off a wicked aura. They have a childish appearance with blue skin and red eyes with black sclera. They are a race that was born bearing clear malice towards humans during the age of the demon lords when most monsters were born to kill humans because of instinct and hunger. They once fed on human fear, screams, and expressions twisted in agony, but now that they have become succubi (inma) in the present, they have come to prefer human expressions slackened in pleasure and ecstasy, and cries of delight. They love depravity and chaos and detest purity and order. They’re the vanguard of the “radical faction” that is plotting to convert all women into monsters and shroud the entire world in a demon realm filled with pleasure.

According to their radical ideology, they enjoy having sex with humans and corrupting them into lewd monsters. When they spot a human that strikes their fancy, they’ll attack regardless of whether it’s a man or a woman. If they assault a chaste and noble man, they’ll make him drown in devilish pleasure using their own body, and transform him into an incubus like an animal in heat overflowing with lust, who, appropriately for a devil’s partner, will desire to have sex with them more than anything.

If they assault a pure woman who has never known a man, they’ll engrave pleasure and desire into her body and soul, and change her into a lustful succubus (inma) that loves impassioned days with her husband and enjoys sex the same as themselves. They love seeing the guy they like drown in pleasure more than anything, and for that sake, they’ll use every part of their tiny body to try and satisfy a man with thorough pleasure. Even though they have a sadistic aura, during sex they give highest priority to the man’s pleasure. Sometimes they don’t just rape men, conversely, they fan the flames of a man’s desire, and let him rape them like a beast or criminal.

A tactic once commonly used by devils was to destroy people by giving them power and wealth beyond what they could handle, but many still use the same kind of method even now. They don’t just have sex with men, they make men’s desire swell beyond what they can handle and drown them in it with excessive love and pleasure by making them home-cooked meals every day, waiting on them hand and foot, and briskly taking care of anything they could possibly need.

What they love more than anything else is the expression of their husband after being drowned in love and happiness in this matter, which from an objective point of view does indeed appear slackened and slovenly. Conversely, they don’t like it if their husband makes a difficult or sad expression, so if he makes a face like that, they’ll extend a hand or tongue to his penis right away, and it will be overwritten with any expression that they love.
