Ichigo Kurosaki is a 15-year-old boy with the ability to see spirits, something that he considers more of a bother than a gift. One day he meets a Shinigami (Death God) named Rukia, who's on the run from a Hollow—a destructive spirit with unfinished business on Earth. As a last-minute measure, Rukia transfers her powers to Ichigo, whose abundant supply of spirit energy makes him a far more potent Shinigami than she ever was! Soon Ichigo is vanquishing Hollows left and right, and meeting other friends at school with similar abilities. However, Rukia's transfer of power is forbidden by the Soul Society (the official name of the spirit world), and when their agents come to Earth to dish out the consequences, Ichigo finds that he might have to challenge the entire world of the dead to save her.
