Tannin is a former Dragon King that was given the title of Blaze Meteor Dragon. He was reincarnated as a Devil by Mephisto Pheles, becoming an Ultimate-Class Devil and helped Issei train in order for him to achieve his Balance Breaker. He is a 15 meter tall purple dragon that has a warrior-like personality, taking a dislike to lazy people and cares for his fellow dragons, despite dragons usually being selfish. He once challenged Great Red when he was still a Dragon King, though Great Red simply ignored him. He wanted to be a Devil for 2 reasons: to participate in the Rating Games and to obtain Dragon Apples. These apples are a necessity for a certain species of dragons, since they need them for survival.
