The Chateau Collapses - The Straw Hat's Great Escape Begins!

The explosion of the Tamatebako brings the towering chateau down, and the falling structure flings Big Mom, Galette, Morgans, and Stussy toward the ground. Katakuri snatches Galette to safety, Stussy escapes on Geppo, and Morgans tumbles down unhurt. Sanji ducks into Bege's living fortress while carrying Luffy, and Caesar lifts the whole group clear as Germa 66 also pulls back, only to learn their homeland is under assault.

To keep his matriarch alive, Streusen calls on his Devil Fruit and converts the doomed building into sponge, while Zeus catches Big Mom an instant before impact. Cream floods the island, though Big Mom only grumbles that the food tastes wrong. Once everyone reaches cover, Bege hands Caesar his heart back, severs the partnership with the pirates, and departs with his crew.

Bege returns Caesar's heart and formally dissolves the alliance, then makes his exit. The Straw Hats decide to flee using the Shark Submerge, with Brook and Chopper assigned to recover the sub. At the ruined chateau, Katakuri splits the forces into two squads, one hunting the Straw Hats and the other chasing Bege.

Big Mom's hunger boils over into a destructive tantrum demanding her wedding cake. Smoothie, disgusted that Opera lied to the family about Luffy and Nami, refuses to let him run and orders him to confront their mother. Katakuri and Brulee resolve to chase the Straw Hats themselves before Smoothie warns them of the rampage tearing through Sweet City.

The adaptation expands several beats: Sanji hunting for Reiju mid-collapse, the pair retreating back into Bege, Zeus saving the plummeting Big Mom, and Caesar wincing as he accidentally crushes his own returned heart. Nusstorte's unit reaching Germa territory is also shown. Unlike the manga, where Caesar vanishes after reclaiming his heart, the anime keeps him onscreen, vainly trying to flag down the departing Straw Hats while everyone ignores him.
