The Aikatsu! New World Festival begins, and Raki is eager to take advantage of it and see as many idols and dresses as possible. While Aine and Mio host the Collaboration Stage at Star Harmony Academy, Raki goes with Yume and Akari to the other schools to see what's going on. At Dream Academy they find the Rock Stage and that Ichigo will be performing with Seira Otoshiro as 2WingS. Yume also gets a surprise when Rola Sakuraba shows up. Both Seira and Rola express their passion for Rock and Roll before performing on stage. The performances give Yume and Akari a desire to perform together.
