Toaru Majutsu no Index SS: Kanzaki or Toaru Majutsu no Index: Kanzaki SS was a series of short stories organized into chapters featuring Kanzaki Kaori as the protagonist, going around the world and space doing missions for the Church of Necessary Evil, however, there is more than meets the eye as each incident is connected.
One is bundled with each limited edition release of the Toaru Kagaku no Railgun anime DVD and BDs, collecting all of them makes it equivalent to a single normal Toaru Majutsu no Index volume.

- There are several references to Norse Mythology, especially that of the Valkyrie and legendary spear of Odin, Gungnir, is prominently featured in the story.
