The preliminaries for the BanG Dream! Girls Band Challenge begin with the top two teams in vote count going to the finals at the Budokan. Roselia and RAS begin performing their live shows while a zoned-out Rokka comes to terms with her failed RAS audition. Meanwhile, Poppin'Party write a new song for their first live show in the preliminaries which they perform in front of a live audience and Rokka. Motivated by Poppin'Party's new song, Rokka quickly rushes to RAS' studio where she is given one last chance to audition. Impressed by Rokka's passionate performance, CHU2 adds her as a (temporary) guitarist, ordering Rokka to become a guitarist worthy of RAS.
