On the day of their first guerrilla show, Sakura and the girls have barely had any time to rehearse, and Junko and Ai aren't sure about joining in. Will they be able to set aside their differences and capture the hearts of the passing pedestrians?

After the trouble at the hot springs, the girls get an opportunity to promote a local legend. After they fail to chicken out, their next gig involves a train to Kashima to steal a muddy spotlight.
