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, Konori 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, Konori 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. Konori arrove at the meeting point and discovers that Wataru has apparently died, where she broke down crying clutching his jacket.[4] Konori 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.

Toaru Kagaku no Railgun S E24 01m 46s

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 Konori 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. Konori 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]

Konori 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]

She briefly reappears on September 2, while looking at the sky together with Aomi from a window of their school.[21]

She also voices her concern for her colleague for wanting to go back to duty at once. 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. She replaced the cameo of Fukiyose Seiri from the manga in the anime adaptation.[22] After Daihaseisai, she, along with Mikoto, Uiharu and Saten celebrate Kuroko's recovery from her injuries and the day that she's not needing her wheelchair anymore at Judgment 177 branch office, much to her chagrin on why they celebrate at the office.[23]

Konori and Aomi are aware of what Kuroko and Uiharu are doing on account of how they have been in many incidents as of late. They are relieved that the other Judgment branches are willing to help them but laments how they cannot notify Anti-Skill without any real evidence. Finally, they wonder why they don't just seal off the entire park. Once all the civilians are rescued, Judgment gathers in one place and one of them performs a quick experiment to demonstrate the flammability of the ampoules' contents.[24] Once all the civilians are rescued, Judgment gathers in one place and one of them performs a quick experiment to demonstrate the flammability of the ampoules' contents.[25][26]

Later, Shaei arrives, pleading them to rescue a stray dog named Pero, also located within the park.

In the end, Kuroko is successful in rescuing Pero, and a tearful reunion happened between Shaei and his friend.[25][26]

Ichihanaran Festival Arc[]

Main article: Ichihanaran Festival Arc

Konori 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. Konori 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]

New Year's Arc[]

Main article: New Year's Arc

On January 5th, Konori was present along with Kuroko at the second defensive line that Anti-Skill set up at School District 23 to halt the destructive advance of "CRC" and provided information to the defenders with her Clairvoyance during the engagement.[28][29][30]

On January 6th, Konori was among the people outside on the streets of Academy City, as many of the city's inhabitants fell under the influence of Acute Kotatsu Syndrome and began rioting in costume in defiance of martial law. Around the time that Kamijou Touma and Aogami Pierce were walking home, Konori was seen with Kuroko and Uiharu. While Kuroko was still some managing some resistance to the phenomena with her sense of justice, Konori viewed the situation with some exasperation and resignation.[31]

Toaru Anbu no Item[]

Dark Justice Arc[]

Main article: Dark Justice Arc
This section requires expansion
Minor expansion/refining[32][33][34][35][36][37]

On August 29th, one year before the main story, Konori was with Aomi and Yamagami Erina, with the trio attempting to find Minamioki Sarusa, the group having supposed to meet on the upper deck of a subway station for their patrol.[32] Unknown to them, their comrade was dead, murdered after trying to investigate a dangerous cult.[35] Erina was recognized by Item, who were riding the other way on the escalator and acted to avoid a potential encounter, with the Judgment girls distracted by a firecracker surreptitiously thrown by Frenda.[32] Item would later see the three putting up missing posters and appealing for information about Sarusa's whereabouts on August 30th,[33][34] before Item themselves learned of the death.[35] On August 31st, the three were forced up in the middle of the night by news that members of Judgment had been defeated, unaware of the true nature of Branch 000.[37]



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.[7]

Furthermore, she can even see through dust, dirt, and even the air itself, eliminating any margin of error introduced by light refraction and attenuation. Average human eyesight has certain limits, as air gradually attenuates light, meaning a person cannot see clearly past a certain distance. Konori, however, can ignore the air in between, so the problems caused by attenuation by distance doesn't apply to her,[38] but it also means she cannot protect her eyes against lightning and sudden flashlights from mobile devices when using her ability.[39]

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.
