Description
Neko musume is a cat half-human, half-yōkai who is a member of the Kitarō family. She was created by Shigeru Mizuki and first appeared in the Shōnen Magazine story Nezumi-Otoko and Neko-Musume. In nearly all adaptations, she harbors a romantic interest in Kitarō. She is officially classified as a hanyō, the same as Nezumi-Otoko, and is one year older than Kitarō.

In her daily appearance, Neko musume looks like an ordinary human girl, but when she becomes angry or encounters fish or rats, she transforms into a fierce bake-neko with sharp claws, fangs, and glowing eyes. Her personality varies across the different anime series. In the 1968 series, she is depicted as cold and indifferent. The 1971 series shows her as strong-willed and tomboyish, with a big-sisterly attitude toward Kitarō and Medama-Oyaji. The 1985 series presents her as openly affectionate and a bit of a tomboy. The 1996 series gives her a more cool, mature demeanor, with less overt jealousy. The 2007 series portrays her as lively, modern, and openly affectionate, often working part-time jobs in the human world and spending her earnings on Kitarō and his father. The 2018 series casts her as cool and tsundere, with a dry and distant exterior that hides a kind and caring nature.

Her primary motivation is her affection for Kitarō and her desire to be close to him, and she frequently tries to earn his attention. She also possesses a strong sense of justice and often helps Kitarō in battles against evil yōkai. She works part-time jobs in the human world to earn money, which she sometimes uses to treat Kitarō and Medama-Oyaji.

In the story, Neko musume serves as a supporting character and a key member of the Kitarō family. She often acts as the enforcer of the group, particularly when dealing with Nezumi-Otoko, and is sometimes the only one willing to punish him for his misdeeds. She has become a main character starting from the anime series and is often positioned as a heroine-like figure, the girlfriend of Kitarō.

Her central relationship is her long-standing, often unrequited romantic interest in Kitarō, who generally sees her as a friend. She has a hostile relationship with Nezumi-Otoko, whom she despises both for his rodent nature and his personality, and she frequently punishes him with her claws. She is close to other members of the Kitarō family, including Medama-Oyaji, Sunakake-Babaa, and Konaki-Jijii.

The character has undergone significant development across the series. Her design has evolved from a childlike appearance in the early adaptations to a more mature and fashionable look in later series. Her personality has also shifted, becoming more modern, complex, and independent over time. In the 2018 series, she is depicted as a tall, cool, and capable fighter, often acting on her own to solve cases. She has also shown increased intelligence and resourcefulness, using smartphones and the internet for information gathering.

Her notable abilities include the transformation into a fierce bake-neko when stimulated by fish, rats, or anger, granting her sharp claws and fangs. She possesses enhanced agility and physical abilities, and she is skilled in hand-to-hand combat. In the 2018 series, she is depicted as a formidable fighter, often defeating enemies on her own and acting as a reliable combatant for the group.
