Following a crushing 21-0 defeat at the National Junior Badminton Tournament, Nagisa Aragaki's passion for her sport begins to warp. Unable to cope with the shame of losing, she starts terrorizing the members of her high school badminton club. Her grueling drills drive some to the verge of tears, while others quit the club outright. As the team loses members and new prospects are too terrified to join, the future of the badminton club looks exceptionally grim. That changes when Kentarou Tachibana joins as the new head coach. He is not only an Olympic-level player but also arrives with a secret weapon: Ayano Hanesaki, the girl who defeated Nagisa six months ago. However, Ayano is not the rival Nagisa remembers; she is a girl with conflicted feelings who wants to distance herself from badminton. With her sporting future now on the line, Nagisa must find a way to confront her fears of inadequacy, heal her rival's troubled heart, and bring victory to Kitakomachi High School's badminton club.
