Asunaro Enoki joins his school's third baseball team, comprised of players deemed unskilled or rejected from more competitive teams. Facing disbandment by the disapproving school baseball instructor, Asunaro becomes part of the effort to save the team. A teammate secures a critical opportunity: a single game against the prefecture's highly-regarded first team. The condition states that a third-team victory will prevent disbandment, transfer the first team's title and privileges to them, and open a path toward Koshien Stadium. Asunaro commits to this challenge alongside his fellow players. Assisted by Kaido, a former first-team member, Asunaro and the team strive to transcend their label as unskilled players. They focus their collective efforts on rigorous preparation for the decisive game against the first team, aiming to prove their worth.
