One day, teenaged martial artist Ranma Saotome went on a training mission with his father, and ended up taking a dive into some cursed springs at a legendary training ground in China. Now, every time he's splashed with cold water, he changes into a girl. His father, Genma, changes into a panda! To make matters worse, Ranma's supposed to be engaged to a girl who doesn't like him -- or at least says she doesn't. Shampoo's great-grandmother Cologne has every intention of seeing her gret-granddaughter marry Ranma, and to that end, she promises to teach Ryoga an ultimate martial arts move -- the Bakusai Tenketsu or "Breaking Point" technique. Can Ranma defeat his greatest rival for Akane's affection? Or a better question might be, does he even want to?
