Eijun Sawamura, a middle school pitcher with a peculiar and unpredictable moving fastball, dreams of leading his local school team to the nationals. However, after a devastating loss in his final junior high game, his life changes when a scout from the prestigious Seidou High School offers him a scholarship. Seidou is an elite powerhouse program where competition for a spot on the bench is more fierce than the games themselves. Eijun must prove his worth in a locker room filled with geniuses, veterans, and rivals, most notably the calm and talented pitcher Satoru Furuya.

As Eijun struggles to refine his raw mechanics and find his identity on the mound, he forms a complex partnership with the brilliant and sometimes ruthless catcher, Kazuya Miyuki. Together, they aim for Koshien, the legendary national stadium. The story is a deep dive into the technicality of baseball, from pitch types and batting strategies to the psychological toll of the bullpen. It is a tale of relentless work ethic, the heavy weight of the "Ace" number, and the uncompromising reality of elite sports where only the best survive.
