Rin Hirakoba (平古場凛) is the only member who likes fair play. He uses Habu, which has the stance of a smash, except that it curves while bouncing, and Giant Habu, which curves immediately after leaving the racket, though it causes his hand to go numb, limiting it to one use per match. He is one of the only players to stand up to Coach Saotome, refusing an order to attack Seigaku's coach, because he felt the match was more interesting.
