SummaryThe prelude takes place where a Saiark attacks and Funassyi and the civilians panicking. Gratefully, the Cures arrived to defeat the Saiark to perform Happiness Big Bang, but with the help of the Miracle Lights given by Ribbon and Glasan. Outside from the victory of the Cures, a girl surrounded in the hospital room was consumed by despair, before suddenly, hears a deep voice, willing to make her happy.
One day, after Megumi and the others help put on a Snow White puppet show at a nursery, she finds a fancy doll that doesn't belong to the nursery. The doll springs into life and introduced herself as Tsumugi, claiming that her homeland, the Doll Kingdom, was under siege by the Saiarks. So, she takes the girls, especially Sagara Seiji, to the Doll Kingdom to explore.
Ribbon calls Blue, who was curious of the title the "Doll Kingdom", before being captured by a dark element from his mirror. The girls encountered and fight against a windmill-inspired Saiark. Cure Lovely uses her Pinky Love Shoot to finish off the Saiark; albeit their victory, Ribbon has no ability to sneeze out the PreCards, with puzzled reactions for everyone, but Tsumugi and the dolls. Tsumugi happily invites the Cures to a celebratory party, while meeting Prince Zeke, whom Hime have an instant monster crush on. The girls enjoy the party, but with Yuko and Iona figuring out that the Doll Kingdom's Saiark is no ordinary enemy and that something is amiss, hidden in this kingdom. While located outside of the castle, Seiji was ambushed by Bee Saiarks and was cocooned to transform into a doll, now found by Tsumugi.
Tsumugi invites Megumi to chat outside the ballroom. When Megumi explains about how fun the Doll Kingdom were, Tsumugi grew upset and ran off to a room where Megumi finally locates the Saiark. More Saiarks appear at the same time with Cure Princess, Prince Zeke, Cure Honey, and Cure Fortune. Megumi pleads her to escape, but she have learned that Tsumugi is the one who possesses control of the Saiarks. Connecting to Tsumugi melancholic story, it is revealed that Zeke and the other doll residents are the dolls belonging to Tsumugi, as Hime's love life was permanently torn apart.
In a flashback, Tsumugi adores performing ballet in the real world; but with an invisible accident, she was unable to move her legs and was taken to the hospital, shutting herself off from her friends and family. She reveals to be the girl from the prelude, and follows the voice that belongs to one of the commanders from the Phantom Empire, Black Fang. The Doll Kingdom was a man-made world invented by Black Fang himself, so he can make Tsumugi gain the ability to walk and dance forever, forgetting her worries in the real world she was currently living. Black Fang warns her that the Pretty Cure is the Doll Kingdom's enemy; and if he dies, the kingdom will fade from existence.
The Cures retreated, and Lovely laments that she was unable to help Tsumugi to walk and dance again in the real world, but the Cures encourage her to help her, until returning to the castle. Together, they try to show Tsumugi what she truly needs to be happy, but they are all ensnared by Black Fang, who truthfully reveals that he stole Tsumugi's ability to dance, creating the power based out of her despair. Zeke and the dolls resides for Tsumugi and the Cures, sacrificing themselves to create her new happiness, freeing all of the Cures, allowing Megumi to reach Tsumugi. Stating her firm desire to help her, Megumi helps Tsugumi realize there are things besides dancing that brings her happiness and stops her flow of despair, freeing the captured Seiji and Blue in the process.
Black Fang summons enough despair to pollute the real world and evolves into a much powerful ego. Blue warns every person on Earth to use the Miracle Lights to power up the Cures, but Black Fang's powerful despair shielded the path of the Miracle Lights. In order to break through the dark barrier, Megumi's undying determination gives Tsumugi the strength to turn her despair into hope, allowing the Miracle Lights and the Shining Make Dresser reach to Megumi, who transforms into Super Happiness Lovely and defeats Black Fang alongside the other Cures.
After assuring Megumi that she does have the power to make everyone happy, Tsumugi returns to the real world and regains the use of her legs, finally able to dance the way she wants again. The girls and Seiji visits Tsumugi's dance recital at the conclusion.
