Trapped inside Bishin's newest Mou-Oshimaida, Homare finds herself inside the story of The Little Mermaid formed from their hearts, where she is a mermaid who encounters a prince resembling Harry, who appears to have forgotten about her. As Homare uses a potion to turn herself into a human to see Harry, slowly realising her feelings for him, Bishin reveals that Harry allegedly already had a sweetheart, hoping to have Homare dissolve into seafoam. However, Homare is encouraged by the other Cures and breaks free of the world, deciding to keep her feelings, and what she learned, a secret.
