Eiri is an art student who works part-time at an antique shop, where he becomes obsessed with Cossette, a girl whose portrait is on sale in the store. Her portrait has a tragic story behind it: people who own the painting have all been murdered in bizarre ways... But when Cossette's spirit appears in front of Eiri, she asks him to save her. After learning that the new owner of the portrait nearly killed himself, Eiri makes up his mind to save Cossette.
