Haruka, Chihaya and Azusa are chosen for the trip to Vacation Island, but they struggle to decide what songs to perform. As Ritsuko is chosen to accompany them in place of the Producer, they decide to have her perform with them. Upon arriving at Vacation Island, they discover Jupiter is also participating in the festival, showing off an impressive stage. As the girls think of how to compete against them, Chihaya suggests they should think of a unique image they can use. As they notice how much music connects people, they decide on their motif; to deliver the world of music to everyone. They manage to win against Jupiter and are soon joined by the others for an encore.
