Ranma ½: The Movie 2 — The Battle of Togenkyo: Rescue the Brides!

With the Tendos, the Saotomes, Ryoga, Shampoo and Ukyo misinterpreting Tatewake Kuno's invitation to his two loves, Akane and 'The Pig Tailed Girl', to try his new yacht, a whole new episode of chaos begins in the already unstable lives of the Saotome/Tendo clan. A mysterious shadow kidnaps first Akane's sister Kasumi, then continues on until all the girls disappear. All except everyone's favorite hydrotranssexual.
