Neko Musume

ねこ娘

aka 寝子

A normally-quiet youkai girl, who transforms into a frightening cat monster with fangs and feline eyes when she is angry or hungry for fish. Predictably, she does not get along well with Nezumi Otoko. She seems to harbor a slight crush on Kitarou, who sees her only as a friend. She bears some resemblance to the bakeneko of Japanese folklore.
