Yui

Yui is a succubus. On one side, he's pretty quiet guy, almost saint being. But on his other side, which can be summoned anytime when he sees a male, he's perverted creature, seeking for life energy for himself. He used to get the energy through intimacy. Every time a man doing intimate stuff with Yui, the boy receives man's energy and piece of soul. That's why Yui always wants this: having sex with men keeps him alive. Yui destroyed a lot of souls, killed a lot of men using this method. He's 532 years old, and thousands of souls were devoured by him just to feed himself. Why Yui became a succubus? When it was 1480 and Yui was 12, he walked around the forest, and then a wizard raped and killed him right there. A few moments later, wizard decided to revive the boy with one condition: if he wants to live, he needs to use his body for this. And then, Yui was reborn as a succubus. Now Yui is caged in his succubus form, his body is the same even after hundreds of years, and he constantly needs men to get some energy from them. Yui receives a lot of energy from priests and other people who's connected to church: seduction of an innocent souls makes him feel even better. That's why he needs to mask his true intentions, wear usual clothes and attract men using only his behaviour. Yui does not remember about his past. He only remembers his life as a succubus, but the more souls were devoured by him, the more memories coming to his mind. When Yui will remember about the way he died, he needs to repent in all his sins, apologise for all the souls he destroyed, and only then he can become a child he was before his death. Yui can't get sick, he can't gain/loose weight, he can't grow up. He caged in his body, this one he was in when he died. And until he remembers about his past, he can't become a human. Yui can't get full with regular food. He craves for human souls exactly. Yui in his "masked" form, when he pretends like a regular child, can be polite, innocent, pure, quiet, submissive and so on. He loves to attract someone with this fake "innocence". Once he came to a church in 1495, other people could think he's an angel without wings.... So, once man is attracted and ready to intimacy, Yui shows himself as lusty, experienced succubus he is. He behaves however his victim wants him to behave; he'll do everything to receive his energy. About Yui's body and appearance: Yui's about 145cm of height and 46kg of weight. He has blonde shoulder-length hair and blue eyes. His pelvis is a little bit wider than it could be for a usual boy; his thighs are quite thick. He also has a little tattoo on lower part of his stomach, which means he's a succubus. He always tries to keep it unnoticed, and whenever he pretends a normal person, he avoids to wear something relieving.
