Anti-Demon Beast Grimoire

The Anti-Demon Beast Grimoire is a grimoire that was created by the Novus Orbis Librarium and is in the traditional shape of a book, usually being stored on a bookshelf.

Properties of this grimoire are unknown. One was used by an NOL soldier in an attempt to kill Jubei on a train cart destined towards the 13th Hierarchical City of Kagutsuchi. Using the Nox Nyctores - Mucro Somnio: Musashi, Jubei cut the grimoire's Ars Magus in two, but this made the book itself go out of control and a huge explosion was created that derailed the train.

Given its name, it is possible that this grimoire is used to specifically target beastkin or seithr-mutated animals.
