The story of Bouyaku Battery follows Haruka Kiyomine and Kei Kaname, a pair of young baseball players who set the field afire as an unstoppable pitcher / catcher battery in middle school. Although they were scouted by elite sports schools all over Japan, the two instead enroll in an ordinary high school in Tokyo, because Kei is suffering from amnesia and his athletic skills have reverted to the level of a rank amateur.
