Hoozuki no Reitetsu
Hoozuki is the aide to the great king of Hell, King Enma. Calm and super-sadistic, Hoozuki tries to resolve the various problems in Hell, including a rampaging Momotarou and his companions. However, he also likes spending his free time on his hobbies, such as fawning over cute animals and raising "Goldfish Flowers."
