When Koguma lets it slip in class that she owns a motorbike, she attracts the attention of Reiko, one of the girls who sits near her. Reiko insists on seeing Koguma's Cub, as well as showing off her own, and is pleased to meet a fellow Cub rider.

As Koguma slowly adjusts to life with her Cub, she mentions to Reiko that her luggage case seems convenient, so Reiko makes a call. After school, the pair visit a credit union, where the manager has an old Cub with a luggage case available to them.
