Join Monkey D. Luffy and his swashbuckling crew in their search for the ultimate treasure, the One Piece.

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...

With Sanji forced into a political marriage by his scheming family, Luffy and members of the Straw Hats enter enemy territory to try to rescue him. The Straw Hats will need to work with allies they don't even trust if they hope to succeed. But first things first: how will they crash the biggest wedding in the pirate world?!
