One Piece is a pirate adventure manga written and drawn by Eiichiro Oda, created in July 1997.
One Piece is a legendary treasure said to be of unimaginable value. It was said to be hidden somewhere deep in the Grand Line, presumably on the last island, Raftel, by the late Pirate King Gol D. Roger. Before Gol D. Roger was executed, he announced to the world that this great treasure, could be claimed by anyone worthy enough to reach it, thereby starting the "Great Age of Pirates."
