While out and about at the amusement park one afternoon, Toshio races ahead to secure the optimum perspective of the upcoming Creamy Mami concert while Yuu leads Midori through a roller coaster ride in which he faints; while taking responsibility for Midori is relatively simple and straightforward, finding a private location to conduct the henshin into Creamy Mami proves to be a challenge for Yuu -- especially when a secluded location is a house of mirrors that causes the henshin to summon a mirror image doppelganger that wastes no time causing an uproar around town. Astonished at the lack of modesty demonstrated by the doppelganger and anguished at the effect it has on Toshio who eventually begins to put two and two together, Yuu decides to get into the act herself after heeding Nega's recommendation to have a mirror on hand; a frenzied pursuit sequence later, Creamy Mami ultimately corners the doppelganger into an iconoclastic strategy that brings about her voluntary return to the mirror.
