Spirit Circle

Fuuta Okeya is an ordinary boy, except for the fact that he can see ghosts. A stunning girl named Kouko Ishigami joins his class and initially behaves aggressively towards him. Fuuta attempts to befriend her, but his efforts fail when she spots the birthmark he typically conceals. She subsequently labels him as her adversary, considers his birthmark to be a cursed mark, and asserts that they share a long history from their past lives.
