A 'Pretty Cure Hunter' by the name of Phantom, who has defeated many Pretty Cures and trapped them in mirrors, learns that the current strongest Pretty Cure lies somewhere in Pikarigaoka. Meanwhile, Megumi enters Blue's Cross Mirror Room and joins Blue, who had been thinking over a lost love, in a trip through one of the mirrors, arriving at Pikarigaoka Shrine. There, Phantom appears before them, showing a particular hatred towards Blue concerning Queen Mirage, and completely overwhelms Megumi, trapping her in some restraints. Just then, Cure Fortune arrives, having sought out Phantom to avenge someone precious to her, but even she is outmatched by Phantom's strength. Megumi manages to break free from her restraints and rushes to Fortune's aid, saying they need to work together as fellow Cures. Combining their strengths, Megumi and Fortune manage to increase their power, forcing Phantom to bring out his sword to defend himself. After Blue convinces Phantom to leave, stating that defeating him would not be Queen Mirage's wish, Fortune reveals that she received her Pretty Cure powers from her older sister, Cure Tender, who was defeated by Phantom. Whilst Blue blames himself for all the misfortune that has happened, Megumi gives him some encouragement, stating her gratitude for being able to become a Pretty Cure.
