Staz Charlie Blood is a strong vampire that governs Demon World's Eastern sector. Despite reports that he is a ferocious and ruthless monster, Staz is simply an otaku infatuated with Japanese culture who is utterly disinterested in human blood. Staz spends his days lounging about, delighting in anime, comics, and games, leaving the management of his domain to his subordinates. Staz is pleased when Fuyumi Yanagi, a Japanese girl, unintentionally walks through a portal leading into the demon world. However, just as he begins to develop an unexpected affinity to her, his territory is assaulted, culminating in Fuyumi's tragic death. She transforms into a roaming ghost, and the heartbroken Staz pledges to resuscitate her in order to be able to see her again.
