Super Cub follows Koguma, a reserved second-year high school student who feels as though her life has been stripped of everything that usually anchors a teenager—no parents, hobbies, friends, or goals. One afternoon, on her way home, she stops at a vehicle shop hoping to buy a motor scooter, only to find that even the cheapest models are beyond her reach. With little money to spare, she is ready to walk away discouraged.
Just before she gives up, the shop owner offers her a used Honda Super Cub for ten thousand yen. Koguma accepts, thinking the machine might add a little color to her otherwise monotonous world. What begins as a practical purchase soon becomes the center of a quiet transformation: as she rides through town and takes on small errands, the motorcycle leads her into modest adventures, new routines, and friendships she never expected to have. In the calm rhythm of everyday travel, Super Cub traces how a simple machine can open the door to independence, confidence, and a life that finally feels like it is moving forward.
