Tannin is a Dragon and formerly one of the Six Great Dragon Kings. He chose to become a Devil so he could participate in the Rating Games and fight various beings, and acquire a territory that grows the dragon apple, a fruit a certain race of Dragons have to eat to avoid extinction, due to the fruit becoming rare in the human world. He was reincarnated as a Devil by Mephisto Pheles, becoming his Queen.
