Maiharu Hiromi kicked off her new life in Kamakura by biking to her first day at Minami Kamakura High School, following her move from Nagasaki. Although she lacked experience, Hiromi narrowly missed a collision with Akizuki Tomoe on her way to the ceremony. Noticing Hiromi's potential for cycling, Tomoe kindly offered to teach her, sparking a strong connection between the two. When the long-forgotten bicycle club was discovered at their school, Hiromi, Tomoe, Kamikura Fuyune, and Higa Natsumi banded together to revive the Minami Kamakura High School Girls Bicycle Club.
