One Piece: Curse of the Sacred Sword

Luffy and his crew arrive on an island in search of a legendary sword rumored to be the most valuable in the world. Soon, attacking marines and a group of mysterious women separate the crew. Zoro turns against his friends to aid an old ally, while Luffy and Usopp find themselves lost in a cave. Meanwhile, the others help a village fend off the marines. After Zoro defeats Sanji in a fight, he takes the sacred pearls-the only protection against a cursed sword that threatens to bring darkness to the world.
