Blade Birth

Blade Birth (ブレード・バース, Burēdo tanjō) is an irregular Sacred Gear that originated after the death of both the God of the Bible and the original Four Great Satans. It is also the counter to Sword Blacksmith.

Summary
Once the god of the bible died, the system he left behind stared malfunctioning and caused several errors all above the world. This sacred gear is one of those errors, it appeared when a person held Blade Blacksmith and Sword Birth together, causing a massive error, shuting down both sacred gears and causing them to react to each other, fusing between themselves and amplifying the "holy" and "demonic" properties of each other.

With the "holy" and "demonic" properties being amplified, the swords made by this Gear can match up to legendary holy and demonic swords like Durandal and Gram, and possibly exceed them, depending on the potential of the user.

Abilities
Blade Birth has the ability to create numerous Holy, Demonic, Holy-Demonic swords of different attributes, shapes, and properties according to the user's will.

As an irregular gear that can create swords matching legendary swords, it can create swords in the image of legendary swords with extra properties and abilities.

Forms
Blade Birth takes the appearance of any sword that the user may think of, and it sometimes also takes the form of magic sigils from where the swords are summoned. It may also manifest as a sheath, and the created swords appear there.

Balance Breaker
The True Holy and Demonic, Law and Chaos (ザー・トルー・ホーリー・アンド・ディーモニック・ロー・アンド・ケーオス), (Shin no shinsei to akuma,-hō to kaosu), is the Balance Breaker of Blade Birth. It summons two blades to the user's hands, each representing "holy" and "demonic" in their truest forms. Law, the shorter blade, uses magic to create barriers and heal, while Chaos, the larger blade, uses magic for attacking, being able to launch waves of destruction and burn with demonic flames.
 * Chaos. the True Demon Blade is one of the sub-species Balance Breakers Blade Birth possesses. Summoning only Chaos to the user's dominant hand, the user's arm is covered in a scaley black and crimson gauntlet with a purple gem, which can channel and gather demonic power.
 * Law, the Truly Blessed Blade is the second sub-species Balance Breaker of Blade Birth. Summoning only Law to the user's dominant hand, the user's arm is covered in a feather covered white and gold gauntlet with a blue gem, which can channe and gather light power.
