One Piece: Baron Omatsuri and the Secret Island
The Straw Hats visit with a recreational island run by Baron Omatsuri, the former captain of a group, who were killed years ago. Being the only survivor, he then started wishing to distinguish them and hating all close-knit groups of pirates. He and his henchmen seed skepticism one of the Straw Hats and capture them one by one, leaving Luffy to free his crew against the hold of the Baron.
