The Crimson Grimoire (紅の魔道書 Aka no Madōsho), also known as the Burning Red (
Sypher Alvar's ultimate desire, the Burning Red, was researched extensively by him to the point of pure obsession. Despite the initial fairy-tale status of the Grimoire, Kokonoe Mercury also sought out the Grimoire's power, sending Kajun Faycott out to the 15th Hierarchical City "Torifune" to find it.
In order to make the Grimoire, a vast number of souls are required as a catalyst, and a Remix Heart. Sypher eventually managed to make his dreams come true, and created the Burning Red, albeit incomplete thanks to the lack of souls used.
Physically, the Grimoire resembles a small glowing orb that can easily fit into a persons palm. When being used, the orb seemingly takes the form of the magic being used, such as lightning being directed from the users hand. The magic launched from the Grimoire is remarkably strong, even when incomplete, managing to easily break the walls surrounding a Kiln.
Hazama is the last known person to be in possession of the Grimoire after Sypher's murder.
