Luffy, a mischievous boy, dreams of becoming the king of the pirates by finding the "One Piece", a fabulous and mysterious treasure. But, inadvertently, Luffy one day swallowed a "magical devil fruit" that turned him into a rubber man. Since then, he is able to contort his elastic body in all directions, but he has lost the ability to swim, the height for a pirate! Over the course of ever more incredible adventures and chance encounters, Luffy will gradually compose his crew and multiply friendships with the peoples he discovers, while facing formidable enemies.
