Dororon Enma-kun

Monsters from Hell have begun crossing into the human world in pursuit of human spirits. As people's minds grow increasingly corrupted, the monsters are drawn to these tainted souls, leading them to violate the ancient rule that forbids their entry into the mortal realm. Tsutomu, a student at Yokai Elementary School, finds himself suddenly attacked by these creatures. His rescuers are Enma-kun—the son of the King of Hell—alongside Yukiko, a snow woman, and Kapaeru. Together, they form the Monster Patrol, a team dispatched to the human world with a single mission: to apprehend rogue monsters and restore order.
