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.
