Ace of the Diamond

Game set. Eijun Sawamura, the pitcher of a novice junior high baseball team, meets with a bitter walk-off loss. For Sawamura, that became his last game in junior high, so he sets a new goal of going to the nationals in high school with his teammates. As he begins his hard quest on studying, a guest arrives unannounced. Her name is Rei Takashima, and she is the assistant director of the prestigious Seidou High School Baseball Team. Takashima invites Sawamura to Seidou after seeing his potential, but Sawamura's reply was far from what she had expected.
