Character:

At first, his self-proclaimed rival for the priesthood exam. They first meet soon after Mikage's death and Hakuren is walking by Teito in the church. Teito mistakes him for Mikage since they look somewhat similar, but upon looking closer, realizes it is someone else. Upon seeing that Teito is training to become a bishop as well, he states that Teito is now his rival. Teito is thinking that there is something about Hakuren that is a bit familiar to him until Hakuren asks Teito whether middle school children were starting to take the exam as well. Teito suddenly realizes that Hakuren sounds a lot like Shuuri Oak, his tormentor from the military academy.
