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...

Stopping by the Sabaody Archipelago to get an expert varnish on their ship, the Thousand Sunny, Luffy and his Straw Hat crew run into trouble when they bristle at the local slave trade. Soon the Navy is hot on their trail, and due to the astounding powers of an animalian warlord, Luffy is spirited away to a distant corner of the sea! Will he ever make it back to his crew and achieve his dream of finding the "One Piece"?
