This impressive sports manga focuses on ordinary boys rather than heroes, chronicling the development of the Sumiya 2 Junior High School baseball team—specifically its successive captains and players—in downtown Tokyo. Takao Taniguchi, formerly a substitute for the second team at Aoba Gakuin, a prestigious junior high school in the baseball world, transfers to Sumiya 2 and becomes the captain of the baseball club. Following steady training, the team attempts to compete in a final match of the regional preliminaries against Aoba Gakuin.
