The seemingly ordinary and unimpressive Saitama has a rather unique hobby: being a hero. In order to pursue his childhood dream, he trained relentlessly for three years-and lost all of his hair in the process. Now, Saitama is incredibly powerful, so much so that no enemy is able to defeat him in battle. In fact, all it takes to defeat evildoers with just one punch has led to an unexpected problem-he is no longer able to enjoy the thrill of battling and has become quite bored.

Years ago, the fearsome Pirate King, Gol D. Roger was executed leaving a huge pile of treasure and the famous "One Piece" behind. Whoever claims the "One Piece" will be named the new King of the Pirates. Monkey D. Luffy, a boy who consumed a "Devil Fruit," decides to follow in the footsteps of his idol, the pirate Shanks, and find the One Piece. It helps, of course, that his body has the properties of rubber and that he's surrounded by a bevy of skilled fighters and thieves to help him along the way. Luffy will do anything to get the One Piece and become King of the Pirates!
