The novel "Arashi no Yoru ni" (One Stormy Night...) by Yuuichi Kimura was adapted into an anime produced by Sparky Animation, Duckbill Entertainment, Baku Enterprise, and Bandai Visual.

This unaired episode was released as part of a special edition Blu-ray. The girls learn from school principal Ryuko that Taiwan is being considered as the destination for their upcoming school trip. Because Taiwan is one of the few advanced cycling nations, she tasks the cycling club with going there as a preliminary inspection for the trip. However, as soon as they arrive in Taiwan, Hiromi and Sandy get separated from the group.

After moving from Nagasaki to Kamakura, Maiharu Hiromi tries to ride a bicycle to her first day at Minami Kamakura High School, despite not having cycled in years. At the entrance ceremony, she almost collides with Akizuki Tomoe, who then offers to help her get back into riding. This gesture deepens their connection into a close friendship. When they learn the school once had a cycling club, Hiromi, Tomoe, Kamikura Fuyune, and Higa Natsumi decide to revive it, forming the Minami Kamakura High School Girls Bicycle Club.
