Ranma ½ (Japanese: らんま½) is a manga, and later an anime, that tells the story of Ranma Soatome, a boy who due to an accident while doing martial arts training in Chine is cursed to become a girl when he comes into contact with cold water, while warm water will return him to a male state. (His father also suffers from this, but turns into a panda instead.)
Why, though, does the name of the manga/anime have the "½"? I assume it has something to do with Ranma's gender bending, but is there an explanation for why the "½"?
