One Piece: The Curse of the Sacred Sword

As part of his quest to find the world's most expensive sword, Luffy and his crew head to an island. The crew was soon split by attacking marines and beautiful maidens. As Zoro betrays the crew to help an old friend, Luffy and Usopp wander through a cave, and the rest help a village fight marines, they help the crew defend their village from the marines. The sacred pearls Zoro takes during his defeat of Sanji are the only defense against the evil sword that will plunge the world into darkness.
