In the American Old West, the world's greatest race is about to begin. Thousands line up in San Diego to travel over six thousand kilometers for a chance to win the grand prize of fifty million dollars. With the era of the horse reaching its end, contestants are allowed to use any kind of vehicle they wish. Competitors will have to endure grueling conditions, traveling up to a hundred kilometers a day through uncharted wastelands. The Steel Ball Run is truly a one-of-a-kind event. The youthful Johnny Joestar, a crippled former horse racer, has come to San Diego to watch the start of the race. There he encounters Gyro Zeppeli, a racer with two steel balls at his waist instead of a gun. Johnny witnesses Gyro using one of his steel balls to unleash a fantastical power, compelling a man to fire his gun at himself during a duel. In the midst of the action, Johnny happens to touch the steel ball and feels a power surging through his legs, allowing him to stand up for the first time in two years. Vowing to find the secret of the steel balls, Johnny decides to compete in the race, and so begins his bizarre adventure across America on the Steel Ball Run.

Gold Roger was known as the "Pirate King," the strongest and most infamous being to have sailed the Grand Line. The capture and execution of Roger by the World Government brought a change throughout the world. His last words before his death revealed the existence of the greatest treasure in the world, One Piece. It was this revelation that brought about the Grand Age of Pirates, men who dreamed of finding One Piece—which promises an unlimited amount of riches and fame—and quite possibly the pinnacle of glory and the title of the Pirate King. Enter Monkey Luffy, a 17-year-old boy who defies your standard definition of a pirate. Rather than the popular persona of a wicked, hardened, toothless pirate ransacking villages for fun, Luffy's reason for being a pirate is one of pure wonder: the thought of an exciting adventure that leads him to intriguing people and ultimately, the promised treasure. Following in the footsteps of his childhood hero, Luffy and his crew travel across the Grand Line, experiencing crazy adventures, unveiling dark mysteries and battling strong enemies, all in order to reach the most coveted of all fortunes—One Piece.
