High Priest

僧正

The High Priest is a "bizarre magician," a magic god, who dwells in a territory beyond a certain layer of the world. According to Nephthys, the High Priest is kind when it comes to judging others, something which comes from him looking down on everyone. [Spoiler] During his fight with Kihara Noukan, it is revealed that High Priest had something to do with the death of Aleister Crowley's daughter; he was then killed by Noukan.
