Ranma ½ is a Japanese manga series written and illustrated by Rumiko Takahashi. It was serialized in Weekly Shōnen Sunday from August 1987 to March 1996.
The story revolves around a teenager named Ranma Saotome who has trained in martial arts since early childhood. As a result of an accident during a training journey, he is cursed to become a girl when exposed to cold water, while hot water changes him back into a boy. Throughout the series Ranma seeks out a way to rid himself of his curse, while his friends, enemies, and many fiancées constantly hinder and interfere.
The manga was released in English in 36 volumes, with later editions combining multiple books into one.
