As a child, Monkey D. Luffy dreamed of becoming King of the Pirates, but everything changed when he accidentally ate the Gum-Gum Fruit, a magical Devil Fruit that gave him a rubber-like body at the cost of his ability to swim. Years later, he sets off on his quest to find the legendary “One Piece.” Luffy and his crew set their sights on Rainbase, the fabled city of dreams, tasked with protecting their royal charge, Vivi. But Luffy finds himself diverted by the cunning pirate captain Crocodile, leading to some tense one-on-one encounters, while Nami faces off alone against the deadly Ms. Doublefinger of Baroque Works as Vivi races to claim her rightful place in the palace.
