Badminton gets the sports anime treatment it deserves, and that means watching a kid who taught himself to be good enough actually learn what good looks like. Ryou's awkwardness isn't a quirk to overcome, it's the real weight of stepping into something bigger than you, with a coach who sees potential before Ryou believes in it himself. The show builds something rare: a story where getting better means accepting help, and where a sister's push matters as much as any tournament win.

Ryou Mizushima discovers badminton by chance in junior high, throwing himself into a club that lacks direction or guidance. Despite the odds, raw determination carries him through to the prefectural tournament, and afterward his talent catches the eye of Ebihara, the coach of prestigious Yokohama Minato High School. The opportunity unsettles him. Mizushima is naturally timid and hesitant, unsure whether he belongs at such an elite program. His older sister Rika pushes him to accept, and the school's roster also includes Kento Yusa, a player Ryou looks up to. At Yokohama Minato, he finally has a proper coach and a group of quirky teammates, giving him the guidance his younger self never had. Now he aims to win the inter-high tournament and one day surpass Yusa.
