Naru Sekiya is an ordinary 14-year-old middle school 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 is introduced to the world of yosakoi dancing. The series' title is a portmanteau (combination) of the first two letters of the girls' first names: HAna, NAru, YAya, MAchi, and TAmi.
