A couple of days ago, One Piece celebrated a massive milestone — the manga selling over 600 million copies — with a wild publicity stunt. Series creator Eiichiro Oda wrote down the biggest secret in his 29-year-and-counting epic, the nature of the One Piece treasure, for the first time. Then he put that piece of paper in a sealed container that was dropped to the floor of the Japanese sea, 651 meters deep. “The truth will rest far beyond anyone’s reach,” the video of the stunt states. But it’s possible that the statement will have to be retracted.
