Neko-Musume
Neko-Musume is a Kitaro Family member and a cat hanyo. She has a romantic interest in Kitaro in practically all renditions. Neko-Musume has undergone the most transformations of any character in the show. Her typical outfit includes a long-sleeved white top, a pink dress with suspenders, pink shoes, and a pink bow in her hair. Her hair is normally in a bowl cut, and the color varies depending on the series.
She appears human most of the time, but when she is angry or sees fish or rats, her eyes change to gold and cat-like, and she bares her fangs. She, predictably, does not get along with Nezumi-Otoko. In most renditions, she has a crush on Kitaro, who regards her merely as a friend. In the sixth anime, she grows taller and loses her childish characteristics, getting an adult, mature physique with longer legs and more delicate features, as well as red stiletto heels.
When Neko-Musume goes into fight, she appears to be able to regulate her transformations, getting a more monstrous, cat-like face with a wide fanged mouth, yellow eyes, and a flat nose. In this state, she has been completely taken over by cat instincts: despite being able to distinguish between friend and foe, she rarely talks, screaming and wailing ominously and charging on all fours, hitting and scratching violently.
