Mutsumi Urushibara

Mutsumi Urushibara (漆原睦 Urushibara Mutsumi), is the counselor of the school Katsuhira is attending. She's a mysterious woman who's almost always seen wearing a white coat.

Appearance
Mutsumi has blue eyes and jaw-length black hair. She has a beauty mark under her left eye as shown in the beginning of Episode 2. She usually wears a lab coat and dark black waist-high pants with a white blouse.

Personality
Initially, Mutsumi comes off as cold and detached, seeming only to care about the well-being of Noriko Sonozaki. In later episodes, she is shown to have caring and motherly qualities, such as when she argues with Kazunao about the effects of the experiment on the Kiznaivers.

Noriko Sonozaki
Out of all the students in the school, she only favors Sonozaki, who she calls "Nori-chan". She even has a Sonozaki key-chain attached to her mobile.

Kazunao Yamada
Kazunao and Mutsumi are both members of the Kizna Committee who work on the Kiznaiver experiment together. They seem to have been friends for a long time, and use nicknames without honorifics when referring to each other.

Trivia
