Tsubaki Koton, feared as the delinquent "monster" of his high school, has been stabbed by a familiar student with a grudge. With no time to treat his injuries, he runs off in search of his ghostly savior, Kabuto, who he fears will lose consciousness if he leaves his side for too long. Luckily, Tsubaki finds him in the alley where they first met and soon gets himself patched up. But as the two grow closer together, the loyal Kabuto--whose status as unfortunately dead isolates him from the world around him--yearns for his handsome friend's touch. If only they knew a certain new transfer student in need of a little penance whose body is just compatible enough...
