XBlaze

The XBlaze (覚醒開放, EkusuBureizu) is one of the functions of the Original Grimoire (原初の魔導書, Gensho no Madōsho, lit. Grimoire of Origin), Code: Soul Eater (コード:ソウルイーター, Kōdo: Sōru Ītā).

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, Chōteisha Tōya Kagari) 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 been born as a self-defense mechanism.
