Along with Hanai, Oki is Nishiura's reserve pitcher. He has more pitching experience than Hanai, but was reluctant to admit it as he doesn't really want to pitch in official games. However, he is inspired by Mihashi's dedication and decides to try his best. Oki is the only left handed player on the team.
