Ranma Saotome is just your everyday, average, teenage martial arts expert who just happens to have a tiny problem. When a training journey in China turns bad, Ranma ends up cursed. Cold water turns him into a lovely girl, hot water turns him back. Everybody seems to want to marry him or kill him, but mostly, Ranma just wants to be a normal teenager again.
Over the years, Ranma as gathered several potential wives. Akane was betrothed to him when they were kids by their parents. Ukyo was 'given' to Ranma through a deal including an Okonomiyaki cart.
