Ryou Mizushima enrolls in junior high and enthusiastically joins the badminton club. Despite the fact that the club lacked a competent coach, Mizushima developed his talents with his own physical power by the time he competed in the prefectural competition. Following that, he is approached by Ebihara, the badminton coach at Yokohama Minato High School. Mizushima, who is indecisive and shy, is hesitant to enter such a prominent institution. However, with the encouragement of his elder sister Rika, he chooses to visit Yokohama Minato. Mizushima, who now has a coach and eccentric teammates, will gain experience that he lacked previously and hopes to win the inter-high competition.
