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 his Straw Hat Crew have formed a new alliance in order to take down the tyrants of the sea, but Trafalgar Law, their brother in arms, is captured immediately by the devious and powerful Doflamingo. Marching with a magically miniaturized army, Luffy soldiers on in search of justice and treasure!
