Hiromichi Kojima (児島 弘道) is the cleanup batter for the professional baseball team, Saikyou Saitama Lycaons. He is defeated by Toa during his time at the training camp after challenging Toua to avenge his relief pitcher, Nakane. After his defeat, he goes into the forest to train himself mentally against Toua but as he trained he injured his wrist. Even with the injury, he decides to challenges Toua to a rematch with the bet that if he wins, he would take Toua's arm. With the One Outs game ending in a do or die pitch, Kojima resolves that he couldn't lose, getting in the way of the ball and making the pitch count as a deadball. He wins the match because of this, albeit not without contention. Toua admits defeat and Kojima makes Toua join the Lycaons, effectively taking Toua's arm and disabling him from gambling ever again in a One Outs game.
