Three Kingdoms counterpart: Cheng Pu

A long-time friend of Saji and Ryomou. He was once a strong fighter and was well respected by others. He often bullied Enjutsu even though it was Enjutsu who was the leader of Nanyo at the time. He has had feelings for Ryomou for as long as they knew each other. Enjutsu got his revenge when he and Kaku tricked Teifu into awakening Ryubi's dragon, and led Teifu to believe Ryomou would get raped if Teifu would not obey him.

A few years later, Teifu was chosen to be one of Nanyo's representatives for the Grest Fighters Tournament, and suffered a horrible beating in a match that left him in a coma. He would have been killed if Ryomou had not interfered in the match, causing him to be disqualified. Teifu recovered from his coma but is now blind and nowhere near fully recovered. Teifu still jokes about blaming Ryomou for getting him disqualified. When Ryomou is left doubting her abilities after losing to Hakufu, Teifu offers her some much needed encouragement. In the anime, Teifu keeps his injuries and also his feelings for Ryomou. However, he does not appear at all in Dragon Destiny, which is where Ryomou discovered her own dragon.
