— Okamoto in in Another Dimension
Okamoto Ippachi is the baseball coach of Teito High School.
Okamoto believes that no matter how a player's technique is polished, or how great the training facilities a player is given, if the players lack spirit they will never win. He is a passionate coach who trains his players during fielding practice, assisting them in harnessing Teito's Iron Wall defense.
