Red Grimoire

The Crimson Grimoire (紅の魔道書), also known as the Burning Red was researched by Nine and meant to be paired up with the Azure Grimoire. It is the ultimate Grimoire that no one has ever obtained. It allows its wielder to use the power of magic, even if they do not naturally possess the gift – making it one of the ultimate and most powerful of Grimoires. Much like its partner Grimoire, the Burning Red was long thought to be a myth.

Seifer Albar'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 also sought out the Grimoire's power, sending Kajun Faycott out to the 15th Hierarchical City of Torifune to find it. In order to make the Grimoire, a vast number of lives are required as a catalyst (much like Nox Nyctores), while a Remix Heart is also needed. Simply, a Remix Heart is the perfect combination of a person and a Grimoire, making Mai Natsume the only known person to have possessed one. Seifer eventually managed to make his dreams come true, and created the Burning Red, albeit incomplete thanks to the lack of souls used as a catalyst.

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 Cauldron.

Hazama is the last known person to be in possession of the Grimoire after Seifer's murder.

Tager was initially meant to be equipped with it, but the failure in obtaining it forced Kokonoe to use the Artificial Causality Weapon instead.
