Known as the 'Silent Hunter,' he is typically expressionless. His strategy excels at counterattacking from a defensive position, and he is said to catch the 'scent' of his opponent's movements. He is rumored to be the man closest to the Three Great Heavens, following Riboku and Hou Ken. He was a war orphan taken in by Riboku. When Riboku heard that his own disciple had been 'utterly defeated by a child' at a rural military strategy tournament, he looked at the board, realized the child's extraordinary talent, and went to meet him out of curiosity. That child was Keisha. At that time, Riboku took Keisha back with him. He is obedient to Riboku and speaks to him using respectful language. Originally a war orphan, his strategic genius was discovered by Riboku after he defeated Riboku's disciple in a village strategy tournament.
