A substitute coach, hired under coach Nishio's recommendation. A brutal coach with a Spartan attitude, on his first day, he fires Minami as manager and ruthlessly beats Tatsuya, Nishimura, and anyone who slacks off on the team. Because of him, the entire team works much harder, but lose their enjoyment of the game, causing many to quit. He holds a grudge against Meisei's baseball team because of some events that occurred when he attended.
