Hirotaka Nagamatsu

Kaiji Itou is a good-for-nothing loiterer who spends his days drinking beer and stealing hubcaps—that is, until he ends up being tricked by his former co-worker. Unable to suddenly repay his friend's huge debt all by himself, Kaiji is offered a shady deal to participate in an illegal underground gamble on a cruise ship. This turns out to be nothing more than the beginning of his new life of hell—thrown headlong into a life-threatening roller coaster of mind games, cheating, and deceit.

Loki, the Norse god of mischief, has been exiled to the human world for what was apparently was a bad joke. Along with being exiled, he’s forced to take the form of a child. He’s told the only way he can get back to the world of the gods is if he can collect auras of evil that take over human hearts, and so to do this he runs a detective agency. Loki is soon joined by a human girl named Mayura who is a maniac for mysteries, and she soon helps out in her own way. However, soon other Norse gods begin to appear, and most have the intent to assassinate Loki for reasons unclear.
