Monkey D. Luffy dreams of becoming King of the Pirates. After eating a mysterious Devil Fruit that turned his body to rubber - at the cost of his ability to swim - he leaves his quiet village to search for the fabled treasure known as the One Piece, said to wait at the end of the perilous sea route called the Grand Line. Luffy cannot sail alone, so he assembles a crew: a swordsman chasing the title of world's strongest, a thieving navigator, a cowardly sharpshooter, a chivalrous cook, and others who join along the way. Their voyage carries them through island kingdoms, Marine blockades and rival pirate fleets, gradually uncovering a buried world history that powerful forces would prefer stayed hidden.
Decades after the execution of the pirate Gold Roger, whose final words sent the world racing to claim his hidden fortune, the seas swarm with treasure hunters. In a sleepy East Blue village, a boy in a straw hat with a rubber body makes a promise to a departing pirate mentor, then pushes off in a tiny boat with no crew, no navigator and no map - determined to reach the Grand Line and find the One Piece.
