In this Japanese animated film, a girl named Lychee goes to the Tendo dojo to settle a score with martial-arts master Happosai. Many years earlier, Happosai gave Lychee's great-grandmother half a magic scroll guaranteed to bring its owner happiness, and her family is still waiting for bliss to arrive. When Lychee's half of the scroll falls into the wrong hands, the whole gang must travel to China for a showdown with the Seven Lucky Gods.
