Grimoire Weiss

Grimoire Weiss, also known as the "white book", was initially released with Nier's help. He was known as the white book, because he is meant to stop Grimoire Noir, the black book. In the past, Weiss was a part of Project Gestalt along with those who became known as Grimoire Noir and Grimoire Rubrum. Grimoire Weiss "only contains a small portion of the Sealed Verses' power," as said by Devola and Popola, meaning that the power of the Sealed Verses are immensely strong.
