It is the seventh day of the new year in Grand Jipangu. Nami, Sanji, and Chopper are on their way to the shogun's castle, delivering a large quantity of rice cakes to be thrown from the castle. Most of the townspeople have gathered there, hoping to catch the one cake containing a precious jewel. Buggy and his henchmen have made several plans to seize the cakes, including the one with the jewel, before they reach their destination. Although his plans fail, Buggy manages to take Princess Vivi hostage. However, Detective Luffy shows up in time to thwart his efforts. In the end, the cakes are safe and everyone eats until they are satisfied.
