Aira and Rizumu hold a slumber party, where Aira and Mion learn that Sonata Kanzaki is Rizumu's mother. After Mion sees how serious Rizumu is about performing "Aurora Rising", she warns her about how dangerous it is. Mion and Rizumu agree to a Prism Show where if Rizumu is unable to pull off "Aurora Rising", she must leave MARs. Rizumu attempts to jump, but "Aurora Rising" overwhelms her. Afterwards, she promises Aira and Mion that she will prioritize MARs while completing her training to perform Aurora Rising.
