Baseball and porn are Hiro's two passions, but a serious elbow injury forces him to abandon baseball. He chooses a school that doesn't have a baseball team, much to the disappointment of his childhood friend Hikari who attends a rival school with renowned baseball player Hideo. Hiro's decision to quit baseball weighs heavily on Hikari and Hideo. Hiro takes up soccer but his fate takes another turn when he meets Haruka, a clumsy girl who also happens to be his father's boss's daughter. Haruka manages the unofficial baseball club at Hiro's school and when the soccer team challenges the baseball club to a game with the intent to embarrass them, it appears as though the baseball club will lose. In a moment of disgust at the soccer team's arrogance, Hiro switches to the baseball club and helps them to almost win the game.
