After hearing from Marine about how she got her Miracle Song from her mother, who died when she was little, the girls decide to visit her old apartment. There, they find an old drawing by Miki, who Marine remembers was her old childhood friend. Meanwhile, Miki makes an announcement that she intends to perform the Miracle Song as her debut single. Marine confronts Miki, who she deduces is the phantom thief who stole her Elements, but she uses her Toys to separate her Elements once again. However, the Elements remain by Marine's side and challenge Miki for the final Element, Amore, who wanted to cut her from the restrictions of the Miracle Song. Encouraged by Milky Holmes, Marine gains the strength to sing the Miracle Song without Amore's help, asking Miki to sing it alongside her.
