Toaru Majutsu no Index SS: Kanzaki (とある魔術の禁書目録SS -神裂火織編-?) is a story written by Kamachi Kazuma, released in parts in the limited edition DVDs and Blu-rays of the first season of Toaru Kagaku no Railgun anime. The individual parts were later collected into Toaru Majutsu no Index: Gaiten Shoku Light Novel Volume 01 alongside Toaru Majutsu no Index SS: Necessarius Special Admission Test and Toaru Majutsu no Index: Road to Endymion.[1]

The story features Kanzaki Kaori as the protagonist, as she goes around the world and space doing missions as an agent of Necessarius. However, there is more than meets the eye as each incident she encounters is connected.
