Pretty Top holds a Halloween festival in the Motomachi shopping district. While preparing for the festival, Mion becomes frightened when she and Wataru get supplies from a dark warehouse. Recalling Mion's crush on Jun, Wataru asks her to depend on him instead. Before Mion is convinced, Rizumu's prank accidentally leads MARs to a stage. To excite the audience, Callings performs a Prism Show, followed by MARs with their new Prism Jump, "Exciting Halloween Night."
