Fuuta Okeya can see ghosts. Besides that—and the bandage he always keeps on his cheek—he's a perfectly normal 14-year old boy enamoured with the new transfer student. Unfortunately, Kouko Ishigami wants little to do with him. A strange ghost that follows her, however, seems to feel quite differently. But, when Kouko sees the strange birthmark hidden beneath the bandage on Fuuta's cheek, she has a change of heart…for the worse. Not only does she denounce him as her enemy, but she claims that the birthmark is a curse she engraved upon his face during one of their many past lives.
What happened between Kouko and Fuuta, and what is the connection to the strange, fantastical dreams that Fuuta begins to experience?
