Seto Ashiya

Seto Ashiya(whose real name is unknown) is a cross dressing, cake loving, exorcist boy. He protects Mikuzu from Oni by exorcising them with his fan that once belongs to his little twin sister, who died years ago while protecting him from an Oni. It is revealed that "Seto" is not his real name, but in reality is his little sister's. His goal is to get enough money to get a sex change, so that he can bring his sister's soul out of the fan and into his body, killing him, much to Mikuzu's dismay. Seto helps Mikuzu get over her fear of men little by little because of the fact that he is a boy who looks like a girl. His companion is a vampire who can turn into a wolf named Kagari. He has a very bright personality and loves food. (Source: Wikipedia)
