Sword Birth

**Sword Birth**, also known as the **Demonic Sword Creation**, is the Sacred Gear wielded by Yuuto Kiba of Rias Gremory's peerage.

## Summary

Sword Birth is among the numerous Sacred Gears created by the Biblical God before his death under the hands of the original Four Great Satans. It is considered the demonic counterpart of Blade Blacksmith, which possesses the power to create many holy swords of different attributes.

## Appearance

Sword Birth can take the appearance of any sword that the user may think of, but all the swords have one thing in common: all the swords created are demonic swords.

## Abilities

Sword Birth can create numerous demonic swords from a combination of the user's stamina and magical energy, which can possess a variety of abilities and attributes and be very effective in both offensive and defensive combat.

Afterward, the user can manipulate the swords that they have created, controlling them to shape, move, and interact with other things and people around them as extensions of their own will. Advanced users have shown to even be capable of remodelling it into a long-ranged weapon by firing a barrage of demonic swords at their enemies, akin to telekinesis.

While activating, it also cloaks the user in a thin layer of demonic aura which increases their natural defense against magical attacks and curses, as well as increasing their base physical capabilities by several times for a limited amount of time before requiring re-charge.

## Known Swords

* **Holy Eraser** (光喰剣ホーリー・イレイザー, *Hōrī Ireizā*): The Light-Devouring Sword. It's a demonic sword that devours light and holy power of common exorcist weapons, but has shown to be incapable of defending against "true" holy weapons like the Excalibur swords.
* **Flame Delete** (炎凍剣フレイム・デリート, *Fureimu Derīto*): The Flame-Freezing Sword. It's a ice-based demonic sword the devours flame and can inflict extreme frostbite onto who ever being slashed by it.
* **Repression Calm** (風凪剣プレッション・カーム, *Ripuresshon Kāmu*): The Wind-Calming Sword. It's a demonic sword that absorbs wind and nullifies Air-elemented magical attack.
* **Fire Sword** (火の剣ァイア・ソード, *Faia Sōdo*): It's a demonic sword made of fire that burns anything it touches. It can generally powerful pseudo-demonic flames of darkness.
* **Destruction Sword** (破壊剣デストラクション・ソード, *Desutorakushon Sōdo*): A gigantic two-handed demonic sword that's about more than 2-meters long and releases an ominous aura with presumably much destructive power. Wielding it requires a lot of strength and the sacrifice of one's speed, therefore leaving it unnecessary for Yuuto due to his speed-based fighting style.
* **Dragon Slayer** (龍殺しドラゴン・スレイヤー, *Doragon Sureiyā*): A demonic sword specifically made to kill dragons and draconic creatures. It's the most difficult kind of demon sword to produce, as Yuuto originally started developing it to stop Issei if he ever enters a berserked state in Juggernaut Drive again. After he gained Cardinal Crimson Promotion, Yuuto stopped working on it, but started to develop it once again to defeat future opponents with the draconic trait.

## Forms

### Sword of Betrayer

**Sword of Betrayer** (双覇の聖魔剣ソード・オブ・ビトレイヤー, *Sōdo obu Bitoreiyā*), also known as the **Holy-Demonic Sword of Twin Supremacy**, is Yuuto Kiba's X-Side Balance Breaker. It is a fusion between a demonic sword and a holy sword, forged together by combining the Balance Breaker power of Sword Birth and the common powers of Yuuto's second Sacred Gear, Blade Blacksmith.

Its existence is said to only be possible due to the death of countless demons, angels, and not to mention the various incarnations of God during the Great War, thus causing an imbalance within the holy and demonic power and allowing the Holy-Demonic Swords to become possible.

## Trivia

* It is a high-ranked Creation-type Sacred Gear.
* While being a wielder of Sword Birth gives the user a natural affinity toward demonic weapons, it doesn't make them a natural demonic sword wielder.
* Since the Dragon Slayer sword iss modelled on the draconic aura radiated from the Boosted Gear, so it has been dubbed the "Anti-Dragon Emperor" sword by Azazel.
* According to Xenovia, it is considered unique among the demonic sword-based Sacred Gears.
