Joy Boy

Lore & Background

Joy Boy is shrouded in mystery, known primarily through the fragmented records carved into the Road Poneglyphs and the Udon Stone. He was a contemporary of the Ancient Kingdom and lived during the Void Century, a period erased from official history books by the twenty kingdoms that formed the World Government. The most significant aspect of his legacy is his interaction with the mermaid princess Shirahoshi's ancestor, who possessed the power of Poseidon. Joy Boy promised to help her and the people of Wano but ultimately failed to fulfill this vow before his death or disappearance.

In Their Own Story

The wind howled across the silent shores of a land long forgotten by history books. In the dim light of a setting sun, a figure stood at the water's edge, tears streaming down a face etched with regret. He looked out toward the horizon where a great sea beast waited in vain for a signal that never came. With a heavy heart, he carved his apology into the stone, knowing that one day, someone else would have to finish what he could not. 'I'm sorry,' he whispered to the waves, leaving behind only his name and a debt of time that spanned eight hundred years.

Reader's Guide

Joy Boy is the catalyst for the final saga, representing the unfinished business of the Void Century. His name appears on the Poneglyphs, serving as the key to locating the final island where the One Piece treasure awaits. Theories suggest Joy Boy was a pirate or a leader who allied with the Ancient Kingdom to challenge the World Government's formation. His failure to save Wano and fulfill his promise to Poseidon is why the world remained divided for so long. Luffy's laughter and ability to eat rubber have led many fans to speculate he might be Joy Boy reincarnated, or at least a successor chosen by fate to settle this ancient debt. The connection between Luffy's Devil Fruit and Joy Boy remains one of the series' deepest mysteries.
