Meisei Academy High School was well-known for their outstanding baseball squad due to the legacy left by Tatsuya Uesugi. However, 26 years after its success, the squad was unable to maintain their record and has since lost their popularity. Souichirou and Touma Tachibana, two stepbrothers, want to resurrect Meisei Academy's baseball team and compete in the National High School Baseball Championship. Souichirou and Touma are students in their second year at Meisei Academy Middle School. Baseball is a sport that both boys excel at. Souichirou has shown to be a great catcher and hitter. Touma, despite his exceptional ability as a pitcher, no longer throws for a variety of reasons.
