He is a wish granting ghost (aka School Mystery No. 7 / Hanako-San of the Toilet ) When it comes to girls, he is very flirty and literally shoves you against a wall and gets in your personal space. When it comes to boys he befriends them, or looks down on them. He doesn't like talking about his past. When he was alive, his name was Amane Yugi, and he killed his brother, Tsukasa Yugi, with a carving knife. He didn't have many friends. He will need you to help him with the other supernaturals.
