Haruno Shiozaki is a seventeen-year-old high school girl in the remote highlands who loves her Honda Giorno motorcycle and rides to school with her friends Anri and Sayo. Seventeen and restless, she dreams of escaping to the city for something more vivid, more alive than what her small world offers. In early summer her parents, who run a boardinghouse and a motorcycle repair shop, take on Cynthia, a lively rider from Australia, to help out. Haruno is fascinated by Cynthia's travels abroad, and meeting the people staying with her family slowly makes her less pessimistic and encourages her to move toward her dream. The OVA is a gentle slice-of-life story told over four episodes.
