This is Ranma Saotome. He is 16 years old and engaged to four girls.  This is pretty much his father Ganma's fault. You see Genma trades Ranma's hand in marrage to anyone who will give them food.  Ranma is a very good martial artist who can usually defeat his many enemies with ease.  There is one problem though. While training in China he fell into a cursed spring. Now whenever he is doused with cold water he turns into a girl.
