Minor Characters

Fujimoto Shirou:

Father Fujimoto was Rin and Yukio's guardian and was also considered to be one of the most powerful Exorcists in the world. He was thought to be the only man in the world that was able to sustain possession by Satan himself and thus Satan was constantly after his body. Fujimoto was able to fight off Satan's attempts at possessing his body through sheer willpower. However after receiving a mental shock from what Rin had said, Satan was finally able to take over his body and later killed him. Fujimoto had a familiar sith cat demon, which he called Kuro, that Rin has inherited. He was a confirmed Aria, Dragoon and Tamer and could possibly have been a Knight and a Doctor as two of those who have studied under him have become these. He was said to be the strongest exorcist on the planet and was the only one to gain the rank of Paladin, the highest rank of the exorcists.

Mephisto Pheles:

Pheles is the Chairman of True Cross Academy and also an Exorcists. After Fujimoto's death Pheles was ordered to kill Rin, however he accepted Rin's proposal in becoming an Exorcist and entered him into True Cross Academy. It has been heavily implied that he is the son of Satan along with his brother, the Earth King,Amaimon. He possesses the unique and peculiar ability of transforming into a small dog after counting down from three in German. How powerful he is has not been shown but he has mentioned that he is a honorary knight, the position two ranks below Paladin. He has been shown responsible for allowing several higher class demons onto campus.

Amaimon:

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.

Arthur Augusto Angel:

The newly appointed Paladin. He was ordered by the Grigori to interrogate Mephisto and captured Rin as evidence. According to Shuru, he's a saint on the outside and a devil inside. He uses the demon sword Caliburn.
