<b>Ukyo Kuonji</b> is one of <b>Ranma</b>'s oldest friends, and was his second engagement after <b>Akane</b>. <b>Genma</b> and <b>Ukyo</b>'s father made a deal that in exchange for the Kuonji family Okonomiyaki cart, <b>Ukyo</b> would become <b>Ranma</b>'s fiancee. When <b>Genma</b> offered <b>Ranma</b>, then just a small child, which he would rather have, okonomiyaki or <b>Ukyo</b>, <b>Ranma</b> responded "okonomiyaki". This prompted <b>Genma</b> to take the cart and leave <b>Ukyo</b> all alone.

Years later, <b>Ukyo</b> found <b>Ranma</b> and tried to take her revenge. Because she was so embarrassed by <b>Ranma</b>'s rejection, she had begun dressing as a boy so that she would never have to deal with the opposite sex again. After a quick match <b>Ranma</b> discovered that his childhood friend, whom he lovingly called Ucchan, was really quite a cute girl. He was very kind to her to make up for his father's desertion years earlier, and <b>Ukyo</b> quickly fell in love with <b>Ranma</b> all over again.

Now <b>Ukyo</b> lives in Tokyo alone and runs Ucchan's Okonomiyaki, a popular neighborhood restaurant among the students of Furinkan High.
