Monsterization is the phenomenon where humans are transformed into monsters via mamono mana infusion. Monsterization only occurs in women. The succubus is a typical monster that possesses this ability. Monsterization occurs when mamono mana enters the body of a human woman. There are several methods for changing a human into a monster, but typically they are infused with mamono mana through sex. When a human woman has sex with a monster, she has all of her essence stolen away and replaced by the mamono mana that pours inside. Once a woman has been infused with mamono mana, her body grows hot, and her thoughts grow vague. Eventually, the mamono mana she was infused with gives her pleasure while gradually remaking her body into that of a monster. Reason rapidly melts away as she indulges in the pleasure of sex with a monster, and the sweet sensation of her body changing to a devilish nature from the inside. Her mind becomes full of nothing but thoughts of pleasure, and before long her body and heart will both be changed completely into that of a monster. There are also other methods of monsterization besides sex, such as being bitten, having mamono mana pour into the body through a wound, expelling essence, also, when a woman spends a long period of time in certain lands such as the mamono realm where mamono mana is contained in the air, or by taking a medicine made with the mamono mana of a succubus. Even after they become monsters, the base is still their original human woman form, and the looks of the woman from when she was human are very much well-preserved; however, her face becomes more devilishly beautiful in a way that attracts men, and her body changes becoming more attractive as well, such to strongly arouse the carnal desires of men. And then, the parts and organs that are defining characteristics of her particular race start to appear (such as the horns, wings, and tail of a succubus). The sexual desire of a woman who has become a monster swells exponentially, and her body naturally throbs, seeking men. In order to taste pleasure more rapaciously, it becomes extremely sensitive. Having sex in the body of a monster gives them a devilish pleasure unlike anything they could have ever experienced while human, which likely makes them become it's prisoner. Also, the special abilities and various techniques for pleasuring men are gained automatically through instinct along with the new body, so they are able to use them naturally even immediately after having just transformed. Soon enough, they'll use them to obtain a man. Just as with the body, the personality and memories from when they were human largely remain intact. However, the mind is warped by monsterization. No matter whether they were once a knight, or a timid village girl unable to even speak to men, the women end up becoming extremely lustful as though they had never even been human in the first place. They become extremely aggressive about getting sex from men. They're shameless
