Neko-Musume, a half-yōkai (Hanyō) from Shigeru Mizuki's *GeGeGe no Kitarō* franchise, also features in the *Yo-kai Watch* film *Shadowside: Oni-ō no Fukkatsu*. She belongs to the Charming tribe and holds Rank A classification in *Yo-kai Watch* media, with a Rank S variant appearing in *Yo-kai Sangokushi: Kunitori Wars* and *Yo-kai Watch: Wibble Wobble*. A member of the Kitarō Family residing in GeGeGe Forest, she is roughly one year older than Kitarō. She maintains close bonds with Sunakake-Babaa and Medama-Oyaji, often showing them respect. Her origins trace back to a 1967 manga debut in *Nezumi-Otoko and Neko-Musume*, though early versions lacked her signature ribbon. Her design evolved significantly across anime adaptations, shifting from a simplistic bowl-cut hairstyle and polka-dot dress to more humanized, feminine appearances. The sixth anime series depicted her with taller stature, adult proportions, purple hair in a bun, red stiletto heels, and sheer pantyhose. Typically resembling a humanoid girl with cat-like features, she possesses pointed teeth, thin oval pupils with yellow sclera, and pointed ears that droop when distressed. Her standard attire includes a red dress with suspenders, a white long-sleeved blouse, red Mary Jane shoes, and a yellow bow projecting cat-ear shadows. When angered or exposed to fish or rats, her eyes shift to gold, triggering a feral Bake-Neko transformation. This form grants enhanced agility, razor-sharp claws, and cat-like reflexes, amplifying her instincts, reducing speech to howls and wails, and causing her to fight on all fours. Her personality centers on a longstanding romantic interest in Kitarō, though he typically views her platonically. She frequently clashes with Nezumi-Otoko due to their cat-rat rivalry, often punishing him for deceit. Notably, some narratives show her exhibiting prejudice against half-yōkai like Nezumi-Otoko, criticizing his human ancestry despite her own hybrid status. Manga iterations depict her attending yōkai primary school with Kitarō and later enrolling in Bizarre Women's University, where she develops an arrogant persona and part-times to financially support Kitarō and Medama-Oyaji. In *Shadowside: Oni-ō no Fukkatsu*, Neko-Musume appears in GeGeGe Forest alongside Sunakake-Babaa, Konaki-Jijii, and Nezumi-Otoko. She encounters human protagonists Natsume Amano and Akinori Arihoshi seeking Kitarō's aid against the Onimaro threat. During this meeting, Nezumi-Otoko impersonates Kitarō for financial gain until Kitarō intervenes, prompting Neko-Musume and the others to assist the group. Kitarō ultimately delegates the primary conflict resolution to the humans. Trivia includes her favorite foods (fish, bonito flakes, rats), her original manga residence near a ramen shop in Chōfu, and her alternate English name "Cat Chick" in Kodansha International's 2002 bilingual comics.
