While excited about being a PreCure, Emiru feels downhearted over not a failed attempt at patrolling the town while Ruru becomes worried about her after Emiru lashes out at each other. After some encouragement from Homare and Harry, Emiru comes to understand the happiness that came from becoming a PreCure alongside Ruru and sorts things out with her. After Emiru's guitar gets destroyed during a battle with an Oshimaida, Hugtan, hearing her plea for an item akin to the Melody Sword, opens a portal that summons two PreCures from another world: Cure Black and Cure White.
