XBlaze

The XBlaze is one of the functions of the Original Grimoire (原初の魔導書), Code: Soul Eater (コード:ソウルイーター).

Information
The XBlaze function turns the Seithr inside the Grimoire into "positive feed-back" and stores that "power" inside the user. During this state no life force is drained however a strong will is needed or the Grimoire will go berserk. It's user's hair and eyes turns red while activated. It is said that only Tōya Kagari can use it.

Tōya was taught this command by the Arbitrator Tōya Kagari (調停者・カガリトウヤ) who's existence is unsure where it came from, though Arbitrator said it could have been born by the Seithr from Ripper or it could have been born as a self-defense mechanism.
