Kouzaku Mitori

Kouzaku Mitori (警策看取) is an antagonist in the Toaru Kagaku no Railgun manga series. 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.

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".

Chronology
14 months prior to the  Daihasei Festival Arc, Kouzaku Mitori was put in 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 Juvenile Hall.

Abilities
The nature of Mitori's abilities are yet to be revealed, but what is known is that she is capable of using a material similar to that used for Powered Suits to 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.

Trivia

 * In the manga series, 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.
