Ryou Mizushima enters junior high and joins the badminton club with great enthusiasm. Although the club lacked a proper coach, Mizushima honed his skills using his own physical strength by the time he competed in the prefectural tournament. Afterwards, he is approached by Ebihara, the badminton coach at Yokohama Minato High School. Indecisive and timid, Mizushima hesitates to attend such a prestigious school. However, with a strong push from his elder sister Rika, he decides to go to Yokohama Minato. Now blessed with a coach and idiosyncratic teammates, Mizushima will gain the experience he has lacked until now, and aims to win the inter-high tournament.
