Sports · Drama · Slice of Life

An unusual pitcher leaves his middle school teammates for powerhouse Seidou, where a crowded roster makes his goal of becoming ace immediately difficult.

Synopsis
The Anime Lad

Eijun Sawamura loses his final middle school game when a stray pitch misses the batter. A scout still sees promise in his unusual style and invites him to Seidou High School in Tokyo. Eijun accepts, entering a powerhouse filled with skilled players. He announces that he will become the team’s ace. Fellow first-year pitcher Furuya has already made that declaration significantly harder.

That pressure makes the dream exciting, because Eijun has to turn raw potential into a reason this powerhouse should trust him.
