Years after the death of the King of the Pirates, two boys set off for the Grand Line. One to be a Marine Admiral, the other to be King of the Pirates. This is their story.

What if the One Piece and the Great Pirate Era really happened, but the evidence was erased? If the most respected person in the world were to discover what the history hides… Would he reveal it to the world even knowing the consequences?

Class 1-A are training daily to become future heroes of Japan, but being heroes may need to be put on hold temporarily as they encounter a villain in a surprise attack, that leaves some of the class stranded on a floating raft that is found by a pirate crew who have just arrived into the New World.
