Yun Chuan is an exceptionally wise teacher of combat, accompanied by his Esper dog, Screamer. In casual settings, however, he's not the brightest man around. With a heart for outcasts and the downtrodden, he tends to see the redeeming qualities in people rather then their faults. Yun Chuan is a man of his word, and expects others to be the same. Once he feels indebted to someone, he will not easily let it go. Throughout his life, this has often caused him trouble, however.
