The Aomatsu Gakuen High School baseball team was bound by the pride of its past as a prestigious school, clinging to outdated traditions, and no one was willing to take on the role of coach. Every year, one of the third-year students served as the coach in name only, doing odd jobs, but this year the third-year students appointed the quiet second-year student, Hiroshi Kido, as coach. They pushed the menial tasks that no one wanted onto their junior. However, Kido, burning with a sense of mission, embarked on a revolution to make the Aomatsu baseball team stronger, leading to a match between the third-year students and the first and second-year students to determine who would take the lead...! With the summer regional qualifiers just around the corner, can this former prestigious school rise again!?
