During junior high, Ryou Mizushima and his friends impulsively join the badminton club. As he develops a fondness for the sport, Ryou works tirelessly to hone his badminton skills until he qualifies for the prefectural tournament. Lacking a coach who can unlock his full potential, he does not consider applying to a high school with a strong badminton team. Instead, he plans to attend a local high school where he can play badminton for fun. However, Ryou's perspective shifts when the badminton coach from Yokohama Minato High School scouts him. The institution not only boasts one of the region's strongest badminton teams but also features Kento Yusa, a player Ryou admires. Though initially hesitant, Ryou decides to enroll with his sister's support. Driven by firm ambition, he begins to gain experience under the proper guidance of a coach—all in hopes of surpassing Yusa one day.
