Amaimon (アマイモン Amaimon), also known as the Earth King (地の王 Chi no Ō), is one of the 8 Demon Princes of Gehenna, wherein he ranks as the seventh strongest, and a son of Satan. Unlike his father and elder brother, Amaimon had little interest in Rin after their first meeting, but his interest grows with each encounter.
Amaimon's host is a teenage boy that he acquired over 1,000 years ago. He has a spike of hair which is lightly colored compared to the rest of his dark green hair and has long claw-like black fingernails. He wears a jacket that has cross bones as buttons. He also wears green arm warmers and a black and pink short sleeved shirt (same color as his spike) under his jacket which is ripped at the ends. When he is in his Demon form and at full power he has longer ears, two horns on his head, an alligator-like tail, and muscular arms like his familiar, Behemoth , all of which are green with red markings. He stands at 172 cm (5'7"); an average height.
Amaimon appears to be calm and collected, but holds his power in a very high regard, very brash and, overall, quite carefree. However, he shows great anger and annoyance when someone ruins his fun, like when Mephisto intervened in his fight with Rin in the Chuchi forest. Amaimon also hates to lose, as after he lost to Rin, during the hearing against Mephisto (anime only), to ensure his victory against the former, Amaimon assumed his Demon form. He is very playful and doesn't take his opponents seriously in battle, which suggests that Amaimon is either highly arrogant, or hideously skilled in combat. He has also been shown to care for his familiar, Behemoth, and showed great distress when Shura killed it (anime only). He does not tolerate being laughed at and does not like to be ignored. He was sent back to "Hell" with his father "Satan".
- In Demonology, Amaimon is the only one who can control Asmodeous, the Demon of Lust.
- (To himself after talking with Mephisto) "Both brother and father have become entranced... How long will it be until Rin joins them? It'd be good to kill a little time..."
- (To Rin Okumura) "Who...? Ah, yes. I'm Amaimon, a Demon king. I'm kind of like your big brother. Nice to meet you."
- (After being stabbed by Rin) "No way, I'm the Earth King... How can I lose?! Big Brother!"
- (To Shiemi) "Let's see...Yeah! I'll make her my wife. Do you promise to be faithful to me in good times and bad? In sickness and in health? Will you love and honour me, all the days of your life? Then seal this convenant with a kiss...."
