Yuan is one of the Taishirou. He was the teacher of Keikoku (Hotaru), who called Yuan "Yun-Yun". Yuan has a rather relaxed attitude and tends to joke around though he is incredibly powerful. In the manga, Yuan is blind and wears a blind fold to conceal his Red Eyes trait. Although known primarily for his skills in Taijutsu and flame techniques, he later reveals a hidden mastery of swordsmanship, which he uses in tandem with the former two disciplines to create a formidable fighting style. His deadliest power is Genshigo, the power of illusions; using it he can fool opponents into believing they have incurred injuries far more intense than they have actually sustained in reality. Yuan seems to care for Hotaru like a son although he has a harsh way of showing it. Later in the manga, it is revealed that Yuan actually hates the Crimson King and never wanted to become a Taishirou. He only did this to protect his family and learn about the secret of his mother's death, the former leader of the Taishirou.
Along with Tokito, he is one of the Taishirou survivors.
