Twenty years ago, the final words of the Pirate King, Gol D. Roger, before his execution ushered in the Great Age of Piracy.
"You want my treasure? Go find it. I left everything in one place."
Twenty years later, on the third day after the future Pirate King Luffy sets sail, an event takes place that catches the World Government and the Navy completely off guard.
Mysterious villages known as ninja villages fall from the sky and appear all over the world, bringing a new kind of color to the Grand Line.
When, during the Paramount War, a man named Kai kicks open the doors to Navy Headquarters, the whole world erupts!!!
"My name is Uzumaki Naruto. I'm a ninja!"
"Oh! A ninja!" Luffy says, staring at Naruto with starry eyes. "Can you use Shadow Clone Jutsu?"
"Of course!"
Beneath the setting sun, the two boys grin and press their fists together. "I'm going to be the Pirate King (Hokage), no matter what."
