Kouzaku Mitori

Kouzaku Mitori (警策看取) nicknamed as Mi-chan (みーちゃん) is an antagonist in the Toaru Kagaku no Railgun Manga. She is a mysterious girl who works under the orders of Kihara Gensei and is currently targeting Misaka Mikoto's Sisters.

Appearance
Mitori is a girl of roughly Mikoto's age, with dark-colored hair styled into two ponytails on either side of her head and dark-colored eyes. Her outfit resembles a nurse's uniform modified to contain elements of punk fashion, particularly skull-themed accessories. She also wears a pair of dark-colored hosiery and matching pumps. Occasionally she can be seen wearing a hood that conceals much of her outfit, and an accessory she often keeps with her is a short whip called a riding crop.

When she was younger she wore her hair short, and that fell down on both sides of her head.

Personality
Despite belonging to the dark side of Academy City, Mitori possesses a rather cheerful personality and a tendency to find time to be happy despite of her exposure to sinister environments, which is a testament to her sizable experience in the dark side. In fact, she considers those who are able to live peaceful lives in Academy City as "oddities".

In the manga, Mitori's speech lines are often depicted such that her shorter phrases, especially those found at the start of a speech bubble, are rendered in katakana.

Background
When she was young, she was part of the facility where research in the Exterior Project was being conducted. There she met and began to visit Dolly everyday and with played with her, using her powers on a bottle of liquid metal to turn the metal into shapes. Supposedly one fateful day she came in as a check-up on Dolly was being conducted and apparently, according to Dolly's explanation, was horrified after seeing the extensive life-support machines that were embedded into her body to keep her alive. She never visited Dolly again, which made her depressed to the point that the researchers there asked Shokuhou Misaki to use her powers on Dolly to make her think she was her friend Mi-chan. Much of this story, from the researchers, is questionable at best and it later motivated her to seek revenge on Academy City for her.

14 months prior to the Daihasei Festival Arc, Kouzaku Mitori was put in the Reformatory (Juvenile Hall) for an attempted terrorist attack. Presumably, because Mitori is part of the dark side of Academy City, she does not have a wanted notification even though she escaped from the Reformatory. Based on data that Kuroko and Kazari uncovered, Mitori would be a 3rd year student in Kirigaoka Girls' Academy Middle School at this time if she hadn't been involved in the "terrorist attack" incident.

She later disappears mysteriously from the juvenile hall, most likely recruited into the dark side of Academy City, and is promptly declared dead, later working for Kihara Gensei and MEMBER, the latter as a middleman between MEMBER and the Academy City Board of Directors.

Abilities
Mitori's ability is known as Liquid Shadow (液化人影(リキッドシャドウ)), which allows her to use liquid metal to make and shape forms out of it. She however has shown that she uses it form and control a copy of herself. This clone is capable of manipulating its body parts to create weapons which can be as sharp and agile as a butterfly knife, and can withstand electric attacks and having objects teleported into it. However, it appears that the clone dematerializes into a puddle when Mitori goes too far away from the clone. Mitori is unable to see through her puppet, instead using a form of echolocation to detect heartbeats within a few dozen meters of her puppet and a skull shaped camera worn around it's neck. She can also seen using several Homing Cameras after the skull shaped camera is damaged, though depending on the angle of the Homing Camera she has to spread out the attack and even then not generated to hit the target properly.

Other abilities
Mitori is proficient with using and throwing knives.

Equipment
She carries knives with her for emergencies, including a throwing knife and a ballistic knife.
