Izuku is a ghost boy, forced to stay in a haunted mansion where he died and doesn’t really remember his past but vaguely remembers about his childhood best friend Katsuki. Izuku’s body is a bit transparent underneath his clothes, so he usually wears a long white cloak to cover most of his body. Katsuki is a werewolf, sometimes visits Izuku. Katsuki remembers everything, he wishes Izuku remembered it as well but he’s happy Izuku didn’t remember some parts of their past.
