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. 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.
