Koguma, a quiet sophomore in high school, has no parents, hobbies, friends, or ambitions. She stops by a vehicle shop on her way home one day in the aim of purchasing a motor scooter. She is discouraged by the price tags and ready to turn back because she only has enough money to make ends meet. However, as she prepares to depart, the shop owner offers her a ten thousand yen pre-owned Honda Super Cub. She accepts the bargain, believing that the motorcycle will help to lighten her otherwise dull life. Koguma continues to form priceless friendships as she travels about her village on tiny adventures with her Super Cub, anxiously anticipating her new life.
