Great King Enma is a giant oni in the afterlife who judges the fate of each deceased soul sending them to either Heaven or Hell.
Enma had Trampire as one of his reapers at one point who retrieved Senbei Norimaki who died of getting hit by a coconut. When they brought Arale Norimaki along with the deceased Senbei, Arale threw a poop on him, making him angry and sending them both to Hell (which they later avoid because of Chivil). After the incident, Enma fired Trampire.
- Great King Enma is based on the Buddhism Yama.
