Synopsis
Demons from Hell are invading the human world to gather human souls, twisting minds and drawing people toward wicked spirits. These creatures violate the laws that forbid them from entering the human realm. Tsutomu, a student at Yokai Elementary School, is attacked by these monsters. He is rescued by Enma-kun, the son of the King of Hell, together with Yukiko, a snow woman, and Kapaeru. These three are members of the Monster Patrol, a team dispatched to the human world to capture and detain the invading demons.
