Age: 15 Birthday: December 23th Blood Type: O Height: 158 cm BWH: 85-60-83 A first year, she is a ninja prodigy. She cares very much for Hibari who she supports the most. She wears an eye patch over her right eye and carries an umbrella (armed with various weapons) at all times. Her summoning animal is the giant squid.

The biggest reason she is sticking together with Hibari because of her little sister; Yagyuu's little sister died due to illness a year before the series, and thought it was her fault that she died. At the start of high school, she saw a girl, Hibari, who looked like her sister. This is also why Yagyuu always promises to protect Hibari, no matter what.
