Description
Amaimon is one of the Eight Demon Kings and holds the title of King of Earth, ranking as the seventh most powerful among them. He is a son of Satan, making him the younger brother of Mephisto Pheles and a half-brother to the Okumura twins, Rin and Yukio. Amaimon has existed for over a millennium, and his current humanoid host body is a highly compatible clone that has survived for more than a thousand years, which explains his physical resemblance to Mephisto. In ancient times, his unchecked rage caused widespread devastation to the land, leading the Emperor of Creation, Shemihaza, to seal his true body into a crystal. The entity that appears in the human world is only a fragment of his consciousness, allowed to act by this seal.
In terms of personality, Amaimon presents a calm and often expressionless demeanor, but this belies a deeply aggressive and combative nature that has earned him the nickname of a mad dog. He is known for being childish, treating battles and fights as a form of entertainment, and he becomes genuinely angry when someone interrupts his fun. Amaimon hates being ignored and has a strong desire to be noticed, which drives many of his actions. Despite his millennia of existence, he can come across as less mature than his much younger half-brothers. He does not take most opponents seriously in combat, an attitude that suggests either high arrogance or immense skill. While he is largely neutral in the political struggles of the demon world, he owes a debt to his brother Samael (Mephisto Pheles), which leads him to occasionally assist the side that protects humans.
Amaimon plays a significant role in the story as an initial antagonist. During a training camp for exorcist candidates, he attacks the students on the orders of Mephisto. His goal is to provoke Rin Okumura into drawing his demon-wielding sword, Kurikara, thereby revealing his demonic nature to his friends. In this fight, he demonstrates his terrifying power, easily breaking Konekomaru Miwa's arm with a simple poke of his finger and sending Rin flying with a flick. The battle is only halted when Mephisto intervenes, trapping Amaimon in a magical artifact known as the Candy Cuckoo Clock. After the events in Kyoto, Mephisto sends only Rin's consciousness to the demon realm to fight Amaimon again. In this encounter, Amaimon uses his full power to easily defeat Rin, but the strain causes his host body to self-destruct.
His key relationships are primarily with his family. He has a complex dynamic with his brother Mephisto, whom he follows out of obligation for a past favor. He develops a strong interest in his half-brother Rin, viewing him as a rival and an object of curiosity, though his initial interest is not as pronounced as that of his father and older brother. He also shows a peculiar fascination with Shiemi Moriyama, which leads him to enroll in the same class as her later in the series. Amaimon is rarely seen without his pet goblin, a creature named Behemoth, for whom he has shown care.
A notable development occurs after his destructive clash with Rin. To suppress his murderous intentions, Amaimon is kept restrained. He is eventually released under the condition that he live a healthy, normal student life at True Cross Academy. Adopting the alias Ambrosius Faust and posing as the chairman's nephew, he is placed in Class 1-B due to his interest in Shiemi. Eventually, Shiemi, having become one of the Three Wise Ones, successfully tames him, forcing him to cooperate with the human forces fighting against major demonic threats.
As the King of Earth, Amaimon has vast control over the land and can generate powerful earthquakes. When he unleashes his true demonic power, a flower-shaped marking appears on his chest, and he grows horns, pointed ears, and a long tail. His arms become massively enlarged and muscular, resembling a dinosaur's. In this full-power form, his strength is overwhelming, capable of incapacitating Rin with a single blow. However, this form puts an immense strain on his host body, which cannot withstand the power for long, so he rarely fights at his full potential. He also carries the Infinite Key, given to him by Mephisto, which allows him to travel freely between the human world, Assiah, and the demon world, Gehenna.
