A boy living in Fusha town, Monkey D Luffy, made friends with Red hair Shanks. Shanks is a pirate staying in the town. Luffy was attacked by pirates. One day, Luffy ate a Devil Fruit called the "Gum-Gum" fruit, giving him the power to stretch like rubber, but he can't swim. After a while, Luffy made bandits angry, so they threw him into the sea. Luffy was nearly eaten by big fish, but Shanks helped him at the cost of his arm. When Shanks leave the town, Luffy was given his straw hat. The straw hat is Shanks's trend mark. Luffy promised him to become a great pirate and see him again.
