At Futatsuzaka High School, first-year student Asahi Toujima (とうじま・あさひ), 15 years old. Having been in the art club until middle school, Asahi is inspired by the slogan "Naginata is the American Dream of high school clubs! Even those with no connection to sports can make their name known nationwide" and joins the naginata club. A strong girl who repels molesters with a kick, her admired senior Maharu Miyaji (みやじ・まはる), fellow first-year and kendo practitioner Shouko Yasomura (やそむら・しょうこ), and tall girl Sakura Konno (こんの・さくら) who struggles with her height… The story of Asahi and her friends, the "Naginata Girls," begins—strong! Fun!! Beautiful!!!
