For training, Mia, Reina, Karin, and Ayami are sent to observe MARs' shows. Dear Crown, a new store, opens next to Prism Stone's new shop at VenusFort, with its designer, Yun-su, taking interest in Aira. At MARs' show, Yun-su gives Aira a crown, while Sho gives her a Prism Stone, declaring him as his rival. Mia, who is irritated at Aira's fame despite her ditzy personality, challenges her directly on stage and performs the Prism Jump "Twinkling Future Star" for the first time.
