Plot
The story adapts several arcs from the One Piece manga, with the Wano Country arc significantly modified due to its incomplete status at release. Characters including Cavendish, Bartolomeo, Sabo, Smoker, Tashigi, and Kuzan help the Straw Hat Pirates free Luffy. After battles with Big Mom, Kaido, and Blackbeard, a final fight against a dragon-form Kaido ends with Luffy's victory and Kaido's flight.

The base game includes 43 playable characters, with 24 more via downloadable content for a total of 67. Returning characters from previous entries are present except Bartholomew Kuma, Caesar Clown, Gecko Moria, Magellan, and Perona. Newcomers to the series include Bartolomeo, Basil Hawkins, Carrot, Cavendish, Charlotte Katakuri, Charlotte Linlin, and others.
