The main character is Loki, the Norse god of mischief. After causing boundless trouble in the land of the gods, Loki is banished to the world of humans and transformed into a little boy. To get home, he must collect "evil auras" (evil spirits), so he sets up Enjaku Detective Agency, specializing in strange and paranormal cases to make his search easier. For better or worse, he attracts Mayura Daidouji— a mystery-crazed teenage girl who quickly appoints herself a member of his detective agency. Soon more gods come down to the human world to kill Loki under Odin's order. Just why is Odin trying to kill him?
From ADV: Private Investigator Loki is certainly an extraordinary fellow with an incredibly demanding profession. While his boyish good looks disguise his true nature, no challenge is too tough for Loki. Not only is it Loki's job to solve mysteries, but he must also protect his own interests, namely his family, especially when those who want him rubbed-out enter the picture. Loki must dig up evidence surrounding kidnappings, murders, suicides, and the like. When old adversaries strike too close to home, Loki must prepare, not only to solve the crime, but to survive the vicious attacks! If the action's hot, you can count on Loki being there!
A little boy with amazing scientific knowledge lives in a lonely mansion with his butler. But their seemingly peaceful existence is quickly shattered as researchers, military personnel, and killer androids start pursuing the boy, determined to seize his experiments and harness his knowledge to their advantage.
