The era of pirates is ruled by chaos, ambition… and monsters.

After the fall of the most terrifying pirate in history, a man whose name once dominated the seas, the world believed the age of ultimate evil had ended. They were wrong.

From the shadows of history, a new legend rises.

Armed with unimaginable power, a blade that can shatter heaven and earth, and a will that refuses to bow to gods or kings, Rono steps onto the stage of the world. From the ruins of God Valley to the chaos of the Sabaody Archipelago, his return sends shockwaves across the seas. The Navy trembles. The World Government panics. Even the mysterious Five Elders begin to fear what has awakened.

Admirals move to stop him. The strongest pirates are drawn to him. Old legends return to the battlefield.

But Rono has only one goal:

To pursue the Ultimate Evil, destroy the false gods who rule the world, and carve his name into history as the pirate who dared to challenge heaven itself.

As alliances form, enemies gather, and the greatest war of the era approaches, one question spreads across the seas:

Is he the world's greatest villain… or the man who will change the fate of the ocean forever?
