Mii Konori is a major supporting character in the A Certain Scientific Railgun sidestories. She is the Chief of the 177th Branch Office of Judgment and a high school student at Academy City. She is the superior/senpai (upperclassman) of both Kuroko Shirai and Kazari Uiharu who tries to make sure they take their work seriously but also keep them safe.

She is voiced by Kana Ueda in the Japanese version of the anime and Trina Nishimura in the English version, the former of whom also voices Rin Tohsaka and Rachel Alucard.


Mii is a tall teenager girl with short black hair and glasses. Her typical attire consists of a dark blue sweater vest with a white undershirt, a yellow handkerchief, a gray and white lined skirt, and a red leather jacket that she wears on certain occasions and has her green Judgment armband with her at all times. She is also slim and has noticably big breasts as noted by Wataru and admits it's because of the milk that she drinks.


Konori is most notably more mature than her subordinates and other girls at her age putting her in the position of leadership. Mii herself is a very kind and respectable person who cares for her juniors and is looked upon as a big sister-like figure by her co-workers. Mii does have typical traits of an average 16 year old teenage girl however, such as in the matters of love. She loves Musashino Milk and drinks it quite often and claims that it's the reason that her breasts are so large. Mii has feelings for Wataru Kurozuma which originally held her back but eventually however, she was able to move on and make terms with her past thanks to his help and has since then moved on. She also likes shopping bags and fashion.
