Handball is wildly popular in Himi City and schools all over Japan come there to recruit talented players for their own teams. Hinezumi High, the sole public school, has been in a slump ever since making it to the Inter High four years ago. In an attempt to reclaim their former glory, they impose a height restriction on club members, under the motto "size equals power." But first-year Shiguma Eito, newly transferred in from Tokyo, is determined to play handball for Hinezumi despite not meeting said criteria.
