Ranma ½
Ranma Saotome and his father, Genma, both practitioners of the Saotome school of anything-goes martial arts, fall into the cursed springs of the legendary training ground of Jusenkyo in mainland China during a training mission. Each spring holds a different curse for any who come in contact with its water, all of which involve who or what has drowned in the spring in the past - Ranma emerges from the spring a girl and Genma a panda, both now cursed to change forms each time they come in contact with hot and cold water.
