The Grimoire of Flandre

The Grimoire of Flandre (グリモワール・オブ・フランドール) is a Notchist Shinto religious text written by Flandre Scarlet, believed to be the word of hers dictated to her followers. The original version was written entirely in Japanese and has been translated into various languages over the years. It has over 114 chapters of varying lengths and touches upon all aspects of Notchist Shinto life, including her doctrine, legislation, and organization.

Many radical Shinto extremist organizations, including the Shintoist Province and Scarlet Devil of Team Crimson, follow the doctrines contained within the text.
