Sacred Gear

**Sacred Gears**, also known as **God's Artifacts**, are items with powerful abilities bestowed upon Humans by **God of the Bible**.

## Abilities

Sacred Gears can have a variety of effects, such as Asia Argento's Twilight Healing granting near-instantaneous healing and Siegfried's Twice Critical doubling the power of the user.

Sacred Gears can also adapt and evolve based on their wielder's thoughts, needs, and feelings, gaining abilities or qualities as time passes. This is stated to be the source of Balance Breaker, and suggested to be the source of the transformation into a Sub-Species.

### Balance Breaker

Sacred Gears have an ultimate state of activation called the Balance Breaker, also known as the Forbidden Move, which is the most powerful manifestation of the Sacred Gear. Once reached, the Balance Breaker can be entered again far more easily than the first time.

An incomplete Balance Breaker can be reached by self-sacrifice on the part of the user, such as when Issei Hyoudou sacrificed his left arm, allowing it to be transformed into a Dragon arm. However, this sacrifice method does not count as a true activation of Balance Breaker.

Reaching the Balance Breaker can be triggered by the feelings of its possessor. Balance Breaker is said to be have been never intended, and that it was a flaw in the system created by God.

### Juggernaut Drive

Juggernaut Drive, also known as Dragon of Supremacy, is a special ability exclusive only to the Longinus Boosted Gear and Divine Dividing, and is considered to be a forbidden move.

The Juggernaut Drive temporarily removes the seal placed on the Heavenly Dragons, and for users that possess insufficient power the Juggernaut Drive will drain the user's life force which is needed to fuel the power, and drive them insane in the process as they cannot handle it.

For other Sacred Gears that have creatures sealed inside (such as the Regulus Nemea), their Juggernaut Drive goes under a different name called Breakdown the Beast, also known as Beast of Supremacy.

The True Longinus has a similar power as well, which unleashes the 'Dying Will' of the God of the Bible, called Truth Idea, also known as Brightness of Supremacy.

## Types

### Longinus

Aside from the normal Sacred Gears, there are also the Longinus. This class of Sacred Gears are also known as Tools that Destroy God.

Longinus are unique top-tier Sacred Gears, with each having multiple abilities compared to a normal Sacred Gear which only has one, and has the power to slay Gods (according to narrative).

There are 13 Longinus in total. However, Azazel has stated that there is the potential for more Sacred Gear to eventually evolve into Longinus, under the right conditions.

Longinus and Balance Breakers were never intended to be created, and are considered to be glitches in the system. The Longinus class of Sacred Gears are named for the first Sacred Gear to achieve this level of power: the True Longinus.

### Sub-Species

Sub-Species are Sacred Gears that have taken on a unique characteristic because of the thoughts and feelings of the wielder. They are more powerful than the normal form of the same Sacred Gear, and will sometimes gain a new ability as well.

Sometimes, both the Sacred Gear in its normal state, as well as the Balance Breaker will be a Sub-Species, like Siegfried's for example. Other times, however, only the Balance Breaker will be a Sub-Species, such as Yuuto's Blade Blacksmith. Even Longinus can gain a Sub-Species Balance Breaker like Cao Cao's True Longinus' Polar Night Longinus Chakravartin or Sairaorg Bael's Regulus Nemea's Regulus Rey Leather Rex.

### Artificial Sacred Gears

It is possible for Artificial Sacred Gears to be created. Azazel, the leader of the Fallen Angels and Grigori, has conducted countless research studies on Sacred Gears.

Artificial Sacred Gears, however, are inferior to the real ones. The Artificial Sacred Gears that Azazel researched and invented have several limits and side effects. For example, after some time has passed, an Artificial Sacred Gear can cause fatigue after their usage and may affect both the powers and abilities of the wielder if said wielder uses them for long periods of time.

**Aaron R. Deathwill** once researched Sacred Gears and created the Sacred Gear Compass (which can locate Sacred Gear holders). He even created a Sacred Gear classified as Longinus (Twin Triaina) but he was no longer interested in Sacred Gears so his future products were no longer related to Sacred Gears. He also modified the original items he created so that they were no longer related to the Sacred Gear System to avoid possible effects if someone later attempted to infiltrate or destroy the Sacred Gear System.
