A Chinese martial arts master, trained in China and became the heir to his Kung Fu style in his temple. He is a man of great discipline and skill. He is sworn to uphold the honor and pride of the ancient art of kung-fu although in time he learns to appreciate the diversity of all the worlds martial arts rather than claiming Kung Fu to be the strongest as he had done throughout the entire tournament.
Despite his great knowledge in his style, he does not open his mind to the possibility of learning from other disciplines at first, but after striking up a friendship with Katsumi Orochi post tournament he appears to want to teach as well as learn at the Shinshinkai Dojo.
