Character:

Ryoga is a childhood rival of Ranma's and is infamous for losing his way thanks to a horrible sense of direction. After spending months looking for male Ranma for leaving before their planned duel, he finally finds him in China but gets pushed into a Jusenkyo spring by female Ranma and now changes into a small piglet. He seeks Ranma out with a large grudge, and discovers Akane who thinks that little “P-chan” is quite cute. Of course, she doesn’t know that it’s really Ryoga, but that doesn’t stop him from falling in love with her. When not upset he's usually shy, humble and polite, especially around women.
