Shun Satan is one of the main characters of Dragons of Fate. He is the son of Satan, the progenitor of the Devil race, thus he is both the oldest and most powerful Devil in existence, surpassing even Sirzechs Lucifer, assuming the position of Supreme Devil (最高裁悪魔, Saikōsai akuma). Acting as both the High Elder of the Elder Council, and the Principal of Kuoh Academy, he is the master of Issei Hyoudou and Rias Gremory, and by extension, her peerage. He wields all of the powers available to the 72 Pillars, including the Phenex Clans' power of healing and the Bael Clans' power of destruction.
