Teito's best friend, Mikage comes from a family of stewards. Despite the fact that his closeness with Teito makes him a target of some students' ill-will in the academy, he remains a bright and cheerful person, sticking with Teito even if others make fun of him. Their relationship as friends involves a lot of Mikage teasing Teito, Teito beating him up in return, and his urging Teito to eat more. Even so, they are still very close, promising each other that they will die together and will always be the best of friends. Mikage also teaches Teito about meeting friends and having compassion.
