Kentarou Tachibana, an enthusiastic former Olympic badminton player, confronts a seemingly insurmountable obstacle: the small Kitakomachi High School badminton team lacks his level of dedication to the sport. The club, primarily led by the talented but moody Nagisa Aragaki, continues to shrink as players are scared off by Nagisa's grueling drills, which push them to their limits and frequently drive team members to tears. One day, however, Coach Tachibana seems to find a ray of hope in the form of Ayano Hanesaki. Ayano possesses a natural gift for the sport, yet she harbors nothing but pure hatred for badminton. When Ayano first joins the club, the source of Nagisa's sullen nature becomes obvious: six months prior, Nagisa suffered a devastating loss against Ayano in the National Junior Tournament, failing to score even a single point. Now finding themselves on the same team, the two girls must move past their negative experiences with badminton and come together to write a triumphant chapter for the school's team.
