The Truth Grimoire (真実の魔道書,Shinjitsu no Madōsho, Grimoire of Truth), also known as the Ammit Cryas (真実の魔道書,Amemitto Kuraiāsu, Grimoire of Truth), is a Grimoire that first appears in BlazBlue: Remix Heart. It reflects the true form of the holder, which is appropriate as it appears as a regular hand mirror. However, if the holder looks at it too long, they will be forced into the Grimoire. In Remix Heart chapter 10, Noel managed to get a hold of the Grimoire by breaking through its sealing Ars. Seifer Albar used the Grimoire to transform his alchemy based monster into something even more grotesque.
