As a boy, Monkey D. Luffy dreamed of becoming King of the Pirates, but everything changed when he accidentally ate the Gum-Gum Fruit, a mystical Devil Fruit that gave his body rubber-like powers at the cost of his ability to swim. Years later, he sets out to claim the legendary treasure known as the “One Piece.” Meanwhile, in Nami’s hometown, a sinister plot forces her to abandon those she loves, only for her sacrifice to be shattered when the ruthless fish-man pirate captain, “Sawtooth” Arlong, breaks his promise. With her village preparing to face a brutal enemy they cannot defeat, Nami’s last hope is to seek help from the very crew she deceived—the Straw Hat Pirates.
