At the distant halls of Fairy Academy, a lively lesson about the Pretty Cures kicks off a tale of magic, rivalry, and heart. A rowdy fairy named Grell and a shy companion En-En are drawn to a forbidden tree, where Shadow materializes and, curious about the Cures, latches onto the idea that they’re just ordinary girls if they can’t transform. Shadow, Chika Sakamoto voices the ominous presence as he schemes to obtain the Cures’ transformation items and grow famous by exploiting their powers.
Soon after, invitations arrive for a grand party at the academy, drawing in rival teams and their loyal allies. The Smile PreCure group—Minako Kotobuki as Rikka Hishikawa / Cure Diamond and Nana Mizuki as Tsubomi Hanasaki / Cure Blossom—receives the call alongside the DokiDoki! PreCure crew, including Mai Fuchigami as Alice Yotsuba / Cure Rosetta and Kanako Miyamoto as Makoto Kenzaki / Cure Sword. The news ricochets through the fairies and girls, hinting at celebration, strain, and the chance to prove their true transformations under bright lights and watchful eyes. Among them, Marina Inoue breathes life into Nao Midorikawa / Cure March, a steady force among her peers, while Nana Mizuki and others bring color and courage to the growing chorus of friends and rivals.
Yet the party’s shimmer masks a looming threat. Shadow covertly steals the Cures’ fairy partners and their transformation items, leaving the heroines exposed to a wave of shadow monsters. One after another, the Pretty Cures face defeat as their powers wane, and Shadow’s plan becomes clear: with the help of a magical guidebook, he anticipates their every move, turning the battle into a calculated trap. The Fairy World itself grows dim as the transformation items vanish, and even the most confident teams find themselves statue-bound and powerless. En-En expresses doubt about the path she’s chosen, but Miyuki Hoshizora / Cure Happy—Misato Fukuen—offers quiet encouragement, urging him to seek aid from the DokiDoki! teams before she is forcibly encapsulated.
With the stakes raised, Shadow unveils his grand design: to erase the Fairy Academy itself and imprison every student. The revelation staggers Grell, who is forced to reckon with the consequences of his own actions. Desperate for help, Grell and En-En travel to find the DokiDoki! teams, pursuing a glimmer of redemption and a route to rescue their friends. The search leads them to allies like Candy and Pop, voiced by Ikue Otani and Daisuke Sakaguchi, whose quick wit and steadfast loyalty help to rally the scattered fairies and Cures.
In the face of overwhelming odds, the fairies and their human partners rally. With the Fairy students and the Miracle Lights on their side, the team works frantically to recover the stolen transformation items and restore the power to transform. The moment of renewal arrives as the items are returned to their rightful owners, permitting the Cures to transform once more and rekindle the light in the fairy world. The combined might of the Pretty Cures returns, and a chorus of courage fills the air as they join forces to confront Shadow’s shadowy army.
The final clash unfolds with dramatic force. Shadow merges his strength into a colossal spider, an embodiment of his deepest fears and ambitions. But the united front of the Pretty Cures—their hearts, teamwork, and restored powers—proves stronger than any shadow. In a blaze of light and resolve, Shadow is defeated and reduced to his original size, his menace dissolving as the academy and its students reclaim their place in the sun. The moment of reckoning also brings a surprising turn: Grell, who glimpses the damage his choices caused, finds new purpose and befriends his own shadow, choosing a path toward goodness rather than notoriety.
With the danger behind them, Grell and En-En decide to become part of the Fairies’ circle within the Pretty Cures, choosing a future that blends their miracle-hearted mischief with true courage. The academy, once scarred by fear, is repaired with care and collaboration, and the festive mood returns. The closing scene settles on a genuine, joyous party that feels earned—an enduring testament to friendship, perseverance, and the belief that there is always a brighter dawn after even the darkest night. The students and fairies share a moment of quiet triumph, then dive into celebration, knowing they will face whatever comes next together, brighter and stronger than before.
