Gameplay

Combat is arena style, following the Grand Battle format rather than a crew brawler. The centerpiece Adventure Mode strings together ten stages navigated from the Going Merry, and characters beaten in battle can join the player's crew or turn up in minigames. A leveling system nudges character stats upward over the course of play.

Story and Setting

Players guide the Straw Hat Pirates across a world map in pursuit of the One Piece, covering the manga's early events up through the Skypiea arc. The mode blends story recreation with side activities rather than delivering a strict retelling.
