As a child, Monkey D. Luffy dreamed of becoming King of the Pirates. But his life changed when he accidentally ate the Gum-Gum Fruit, an enchanted Devil Fruit that gave him the ability to stretch like rubber. Its only drawback? He'll never be able to swim again--a serious handicap for an aspiring sea dog! Years later, Luffy sets off on his quest to find the "One Piece," said to be the greatest treasure in the world...

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!
