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...

In the salty city of Water Seven, Luffy and his Straw Hat crew are fighting for their lives, and for their beloved caravel, the Merry Go! The crew starts to splinter when they hear their ship may be beyond repair...and the damage goes even further when their newest member, the mysterious Nico Robin, is blamed for the attempted assassination of Water Seven's mayor! Is Nico Robin secretly an agent of darkness...or, even worse, a World Government operative?!
