Ukyo's father

Ukyo's Father is the unnamed father of Ukyo Kuonji and was once good friends with Genma Saotome. However, this friendship wore thin when Ranma continually defeated Ukyo and got free Okonomiyaki. This made Ukyo's Father decide that Ukyo should marry Ranma and gave Genma his Okonomiyaki cart as dowry, however, Ranma and Genma left with the cart but forgot to take Ukyo with them.

Ukyo Kuonji Intro
Ten years prior to the events of the series Genma and Ranma are in a town as they travel on their training journey. While there they discover Ukyo Kuonji and her father who make and sell Okonomiyaki. Ranma quickly becomes friends with Ukyo, but this feelings are one-sided as Ukyo hates Ranma for continually defeating her (although Ranma doesn't realises this). When Ranma defeats Ukyo he gets free Okonomiyaki from her father (to his annoyance).

Eventually Ukyo's father decides that Ukyo and Ranma should get married and proposes this idea to Genma. At first Genma refuses and says that Ranma is "already promised" to someone else. However, Genma quickly changes his mind when Ukyo's father says he was going to offer his Okonomiyaki cart as a dowry. Unfortunately for Ukyo and her father, Genma just took the cart and ran, leaving the two of them without a fiancé or a source of income.

Hard Battle
While Ranma and Genma they find Ukyo and her father's business and eventually Ukyo ends up playing a "game" with Ranma that each time he beats her he gets free Okonomiyaki (it's never mentioned what happens when Ukyo wins, since she never does). One day while Ukyo and Ranma are distracted and eating some Okonomiyaki, Ukyo's father tells Genma he wants Ranma to marry his Ukyo. At first Genma is against it as Ranma's already spoken for. Ukyo's father says that's a shame since he was going to throw in his Okonomiyaki cart as a dowry, this causes Genma to quickly change his mind and accept. However, Genma takes the cart and runs, leaving behind Ukyo without a fiancé or a source of income.

Relationships
With Ukyo: Ukyo's father seems to have a good relationship for his daughter and seems to want the best for her, hence why he wanted her to marry Ranma after being defeated by him so many times. In the anime Ukyo's father is also shown to do typical duties of a father, the most notable of which being telling Ukyo to "watch her mouth" when she badmouths Ranma out of earshot of Ranma.
