Pirate
One Piece is set in a vast oceanic world filled with islands, dangerous seas, and ancient mysteries. The legendary treasure, the “One Piece,” lies hidden at the end of the Grand Line—a perilous route guarded by natural and supernatural threats. The world is ruled by the oppressive World Government, opposed by pirates, revolutionaries, and secret organizations. Themes of freedom, discovery, and ambition drive the narrative, as exploration and conflict shape the fate of the world.
