The opening starts with the Thousand Sunny sailing down a stretch of the open ocean whilst dodging cannon shots. The Straw Hats then appear in front of the Sunny before dissolving into differently colored rays of lights that shoot up toward the sky. Each of the Straw Hats are shown one by one, doing a different pose before the title logo appears.
It then cuts to Luffy facing Charlotte Katakuri in the Mirro-World, with the two clashing Haki-imbued fists. We then see shots of Jinbe performing a Fishman Karate punch, Brook using his soul projection before slashing out with Soul Solid, Nami using her Clima-Tact to bring down several bolts of lightning, and Chopper transforming into Monster Point and blocking Big Mom's sword with his fingers. It cuts to Luffy dodging multiple mochi punches from Katakuri, and the two of them clash giant fists before trading blows to the face.
The next shot shows Sanji and Pudding staring at each other with the giant wedding cake and rolls of memory film in the background. It then cuts to Capone Bege shooting at a charging horde of Big Mom Pirates while Chiffon, Pez, Vito, Gotti and the Fire Tank Pirates surround him jubilantly. Next is a shot of Pedro and Carrot, with Carrot's eye overlaying this; this eye becomes the moon, with a shot of Carrot activating her Sulong form below it. We then see a shot of the Straw Hat Pirates standing next to each other as they sail into the sunrise.
After this is a shot of Luffy using Kenbunshoku Haki to foresee Katakuri's attacks, which is followed by a scene of the Vinsmoke Family members using their signature abilities. We then cut back to the Mirro-World, where after Katakuri removes his scarf (revealing his face starting Episode 857), Luffy activates his Snakeman form, although only the silhouette is seen. Then, a series of shots consisting of Zoro performing an attack, Sanji and his team completing the wedding cake, Usopp and Franky fighting Marines, Charlotte Flampe and her minions in the Mirro-World, Robinsubduing a group of attackers, and Charlotte Oven and his army on Cacao Island guarding the last mirror. Big Mom then appears with her face in shadow and Prometheus igniting her hair as she raises Napoleon to attack, and Luffy then appears in front of her before jumping forward as the other Straw Hats appear with him.
