Shampoo

Shampoo is a martial arts girl from China's Joketsuzoku tribe. She initially pursued Ranma all the way to Japan to exact revenge after losing to his female form, as dictated by tribal law. However, upon suffering a second defeat at the hands of his male form, her feelings shifted dramatically into passionate pursuit, and she settled in Japan. She works at the Nekohanten, run by her great-grandmother Cologne, and due to a curse from Jusenkyo, she transforms into a cat whenever cold water touches her. Acting with bold determination and a willingness to employ clever tricks, she stands as one of the most formidable rivals vying for Ranma's affection.
