One Piece Movie 5: The Curse of the Sacred Sword

Synopsis:

When Zoro disappears during his guard shift, the crew of the Going Merry naturally head to the nearby island to search for him... an island that, according to legend, is home to the Seven-Star Sword that treasure-loving Nami is just itching to get her hands on. But when the islanders' less-than-friendly welcome is quickly followed by the appearance of a less-than-friendly Zoro, the crew is in a pickle. Has Zoro betrayed his nakama? The Straw Hat Pirates are in for a new adventure as they try to track down their wayward friend and solve the mystery of the Seven-Star Sword!
