Toaru Majutsu no Index SS: Necessarius Special Admission Test (とある魔術の禁書目録SS -『必要悪の教会』特別編入試験編), previously known as Toaru Majutsu no Index SSS is an upcoming light novel written by Kamachi Kazuma, to be released in parts in the limited editions of the Blu-ray and DVDs of the Toaru Kagaku no Railgun S anime.

The story is wholly unknown, but it apparently revolves around the Amakusa-Style Remix of Church being tested by the Church of England to become part of it.
