Toaru Majutsu no Index Wiki

Konori Mii (固法 美偉 Konori Mii?) is a recurring character in the Toaru Kagaku no Railgun side story. A high school student of Academy City, she is a Level 3 esper and is Chief of the 177th Branch of Judgment where Uiharu Kazari and Shirai Kuroko work. As their senpai and chief, she tries to make sure both girls take their work at Judgment seriously and at the same time wants them to be safe.


Konori has short black hair, blue eyes, and wears glasses. She has a red leather jacket that she wears from time to time. Her measurements are B85-W60-H81.[1][2] She is 163cm tall, and weighs 50kg.[3]


Konori displays a responsible and motherly maturity rarely found in girls of her age; an attribute that earned her station of leadership in the 177th Judgement Branch and the universal respect of her juniors, to whom she is a lovingly-kind and reliable big-sister. That said, she is still a teenage girl who shows a warmly mischievous streak when at ease, and can be just as tender-hearted and vulnerable as any 16 year old girl when it comes to matters of love.

She enjoys Musashino milk, a trait which she has adopted from Big Spider leader Kurozuma Wataru, and she says that it is the reason why her breasts are large.[4] She displays an obvious affection to Kurozuma Wataru. She is also very fond of designer bags.[5]


Two years before the start of Toaru Kagaku no Railgun, Konori Mii ran into an obstacle as an esper and felt unable to surmount it. That difficulty led to her feeling as if she had no place she belonged.[4]

A stylistic flashback of a young Konori Mii.

During a rainy day, Mii encountered a scuffle between Big Spider and another group near an artificial river bank. She later saw that Big Spider were trying to save a little boy and admired the group, especially it's leader Kurozuma Wataru. She later joined Big Spider and their escapades, donning a red jacket to show her place in the group. Eventually, Wataru discovered that she was (at the time) a level 2 esper, and confronted her about this, asking if she really intended to stay in Skill-Out forever, and that she should consider what she was going to do. Shortly afterwards, Hebitani Tsuguo, a member of Big Spider, was captured by an enemy group and forced Wataru to come to their meeting point alone. Believing it to be a trap, Mii pleaded to Wataru to not go, Wataru, however, did not relent to her pleas and told her that she perhaps did not belong there after all. He said that the place they were is not where she should be carving her name, referencing the "love umbrella" she had drawn with their names under. Mii arrove at the meeting point and discovers that Wataru has apparently died, where she broke down crying clutching his jacket.[4] Mii left Big Spider not long afterwards, but kept her red jacket.

At an unknown point afterwards, she reaches level 3.

Konori, at an unknown time, joined Judgement. She became part of the 177th branch, the same Shirai Kuroko would become a part of. The two would eventually find themselves in the middle of a post office robbery. During the robbery, Kuroko recklessly charged one of the assailants. Konori attempted to intervene, and was injured in the process. The injuries, however, were minor, and she was treated afterwards.[6]

Eventually, she became the Chief of the 177th Branch of Judgment.

Main article: Silent Party Arc

Judgment crashes the Silent Party.

On the night before the Silent Party she calls her roommate Yanagisako Aomi, asking her what she thinks of Academy City.[20] It is here that is likely that Mii asks Aomi the favor of asking Judgment to participate against the Silent Party and protect the Academy City Research Exhibition Assembly venue from STUDY. She somehow has the authority or seniority to do this, and she later rallies a countless number of them just after the break of dawn. Mii once again dawns her the red leather jacket and waits at one of the venue entrances for the Academic Assembly, despite having no weapons and offensive abilities. She greets the Powered Suits controlled by Diffusion Ghost there, apparently waiting for Aomi and the others. When they arrive, they perform Kuroko's catchphrase, and proceed to do battle with the Powered Suits in order for Mikoto to deal with STUDY herself.[21]

Mii acts as a field leader throughout the battle, and is later informed of the AIM bomb Aritomi Haruki released. She tells that she will have the members of Judgment who are "science-types" aid in the calculations in stopping the AIM bomb but they are inadequate. She later views the Ekaterina II S being launched into the upper atmosphere after Mikoto somehow finds the proper "computer" to calculate how to launch it and use it against the AIM bomb.[21]

At the day of Daihaseisai, September 19th, on a competition venue, she takes Shokuhou Misaki's purse of remote controls, as they are not allowed in the competition Misaki participates in.

Ichihanaran Festival Arc

Main article: Ichihanaran Festival Arc

Mii debuts in Toaru Majutsu no Index novels during the arc. She appears with Shirai Kuroko across the road from where Uiharu Kazari is. As members of Judgment, it is her duty to aid Anti-Skill during the Ichihanaransai. Her first action is to call out to Aogami Pierce for questioning, deeming him to be a suspicious person. Kuroko questions her on why they couldn't just throw him into a cell, as there are cases and mysterious reports that are needlessly driving down their efficiency, especially about rampaging Rhinoceros beetles. Mii says not to take her frustration on Aogami, to which she then asks for his belongings to check them.[27]

That was the 43rd time he had been questioned by authorities that year.[27]



Her ability is Clairvoyance (透視能力クレアボイアンス Tōshi Nōryoku (Kureaboiansu)?, lit. "See-through Ability"), which is similar to x-ray vision, allowing her to see hidden things such as concealed weapons. Her ability is listed as No. 00484 in the Bank.[7]

Other abilities

She also possesses a formidable level of expertise in basic Judgment combat training, which coupled with her apparent immunity to surprise, makes her more than a match for most combatants in Academy City.
