Ep. 18: The Picture Book's Secret! What is a Princess?

Haruka and Yui attend an autograph session for Yume Mochizuki, author of The Flower Princess. Haruka is disheartened when Yume reveals she will not continue the story, explaining that conflicting fan theories made it better to leave the princess's fate to imagination. Twilight then traps everyone in glass mirrors to harvest despair. Overpowering the Cures, Twilight tries to destroy Haruka's book, but Haruka protects it, inspired by Yume's advice to become her own princess. This resolves into the Lily Miracle Dress-Up Key. Haruka, Minami, and Kirara combine their new keys to defeat Twilight with the Trinity Explosion attack. Yume is later revealed to be the principal of Noble Academy.
