Principal Murayama

former captain of the baseball team from 43 years ago, when the team went to Koshien. He harbors a resentment for the current baseball team as he views them as tarnishing the legacy he left behind, and is willing to do anything to get them all expelled. However, after witnessing their first game against Yoga Daiichi, he starts to regard the baseball team more positively. When Yoga Daiichi's coach threatens to press charges of assault against Kawato for hitting him during their game, Murayama takes the blame for Kawato and resigns.
