Also known as the "Earth King". Amaimon is supposedly the second son of Satan and another Demon Prince of Gehenna. Unlike his father and elder brother Mephisto, Amaimon had little interest in Rin after their first encounter. Fitting with his title, Amaimon has vast control over the land as he was able to start an earthquake while being pinned down by Rin. He has been shown to take odd interests in things as he wished to tour Japan upon arriving instead of seeing Rin. His name is derived from the demon Amaymon.
Amaimon has green hair that starts from light green to dark green. He has dark sea foam colored eye's and also has a little point at the top of his head.He loves to eat candies.
