They go to the girls next show and are run off by their fans. Later on, they meet their fans again and run off. Then, they go around town trying to get rid of everything that would tip off Ami's granny that she is a rock star. She finds out that Ami and Yumi are rock stars and is proud of Ami for making her own decision.
