She has wavy dark green hair which she often wears in a pony-tail; she also has lime green eyes, where she wears glasses over them.
Though well-intentioned and kind, she is timid and is terribly lacking in confidence. She is also clumsy and though slightly incompetent in working as a member of Anti-Skill, she is still trusted in taking dangerous operations. She is once seen to fire her weapon while her eyes were closed.
She is a teacher of an unnamed school, and is also a volunteer of Anti-Skill, where in the anime adaptation she is often partnered with Yomikawa Aiho. She is also an avid player of the Gekisho series of fighting games, and specializes in the character Jamie, to the point that she is called Empress Jamie for her skills on using the character.
