A woman of the late Warring States period whose name was recorded in the documents of Netsumura, Shinshu. She is regarded as a female ninja (kunoichi) that served the Takeda clan of the Kai Province and a descendant of Mochizuki Izumo-no-Kami, but it is unsure whether she was actually a ninja. In a sense, her existence may be a sarcastic answer to the proposition called “renowned ninja”, which is a contradiction for a ninja that should make a principle to keep his activities covert.
