One Piece (Omnibus Edition), Vol. 33: Includes vols. 97, 98 & 99

Luffy and crew regroup on the Sunny, their trusty vessel, to continue the battle against fearsome Emperor Kaido. But when their backup doesn't show, they have to go it alone against the pirate known as 'the strongest creature alive.' Things look up when they're joined by some unexpected allies in the land of Wano, but it turns out the enemy also has some surprising (and terrifying) friends!
