Naru Sekiya is an ordinary 14-year old girl who likes fairy tales, but is worried about her lack of other interests. She has a chance encounter with a "fairy", a foreign girl practicing dance at night. On a spur of the moment, Naru asks to join her, and she is introduced to the world of yosakoi dancing.

Normal appearance, normal intelligence, normal in arts and sports... just normal. This is the entirely normal 14-year-old, Naru Sekiya. While she admires "Heroines" she continues to live a normal life until one moonlit night she meets a fairy. This foreign girl then guides her into the extraordinary world of the yosakoi dance.
