Anti-Monster Grimoire

The Anti-Monster Grimoire (対魔獣用の魔道書) is a grimoire in form of a hardcover book. It has unknown properties.

This grimoire was used by a soldier of the Control Organization on Jūbei during a train ride to the 13th Hierarchical City of Kagutsuchi. It created a magic circle and performed an attack based on a Magic Formula, but Jūbei cut through it with his Musashi. The officer got knocked away by the blast from that circle, and the grimoire went out of control, creating more magic circles, with it eventually destroying the train wagon.
