Tsubaki Koton is a monster—a violent delinquent with a chilling past and a terrifying image to match. No other student dares to approach him, not even after transferring to a new high school. His anti-heroic acts of selflessness end only in bloodshed and rumors that spiral out of his control. Then, one fateful night, he's followed home by a stranger who sets out to change his life for good.

This boy, stubborn and hauntingly beautiful, is the pure-hearted Kabuto Yuuki, with his stunning jewel-like eyes that see past Tsubaki's fearsome façade. But although someone finally sees Tsubaki for who he truly is, Kabuto cannot be seen at all. After all, Kabuto is a ghost.
