Ranma 1/2 the Movie 2: Nihao My Concubine

The story puts all the characters on a desert island after a storm wrecks Kuno's yacht. Suddenly the girls start disappearing one by one, until it is revealed that they have been kidnapped to the neighboring island of Togenkyo, under the rule of Prince Toma and his entourage. The island has a spring similar to the "Drowned Man Pool" in Jusenkyo, so Ranma, Ryoga, Genma and Mousse are interested in it not only to rescue the kidnapped girls but also to cure their curses. This movie features some of the series' best-animated fight scenes, which do an excellent job of showcasing the skills of supporting characters such as Mousse and Kuno Tatewaki.
