Loki, the Norse god of mischief, has been exiled to the human world for what apparently was a bad joke. Along with his exile, he is forced to take the form of a child. He is told that the only way he can return to the world of the gods is by collecting auras of evil that take over human hearts; to achieve this, he runs a detective agency. However, at some point, other Norse gods begin to appear with the intent to assassinate him for reasons that remain unclear.
