Sunshine!!

As the girls keep practicing for the regional qualifiers, some of Chika's friends, having seen everyone's efforts, decide they want to become idols and help the school. Despite almost the entire school showing up to support, Riko reveals that the rules prevent them from joining the group on stage. As Aqours take the stage, they put on a pre-show performance about how they came to be formed and what makes their town so great before performing their song, during which Chika calls down everyone to join in.
