When the soul of a top "Dungeon and Fighter" player is torn into four parts and thrown into the world of "One Piece" - the God of War, the Sword Master, the Wandering Gunner, and the Summoner, the four major professional incarnations arrive at the same time. They share the same mind, interconnected memories, and overlook the sea from a prophetic perspective. This is not a simple time travel, but a four-in-one grand strategy that rewrites history.
From the Four Seas to the Grand Line, from the Navy Headquarters to the Final Island, four identities advance simultaneously along four completely different paths: the Justice Navy, the Free Pirates, the Underground Emperor, and the Iron-Fisted Monarch. When they finally unite, they will subvert not only the rule of the Celestial Dragons, but also the eight-hundred-year-old rules of this world.
