Alaya

Arayashiki (阿頼耶識), AKA Alaya (アラヤ), is the unconscious, universal will of humans. All humans are tied to it.

Alaya is the wish of humanity to avoid destruction, just like Gaia is the wish of the Earth to preserve life.

The Counter Force born from it is called the "Beast of Alaya", made to match up all harm targeting the entire humanity. Its way of acting indirectly is by boosting the strength of a particular human. In the present era, Joan of Arc received that boost from Alaya.

Making a contract with Alaya, one receives a support in power that goes beyond the standard of humanity, becoming a hero; but after death, he will be used for eternity by the Counter Force as a Heroic Spirit, a Guardian.

Counter Force
The Counter Force is the balance of powers (抑止力 yokushiryoku) that aims to maintain and prolongate the present world, a safety device with no consciousness.

Gaia's Counter Force lets humans live, although it doesn't care about them as long as the world is safe. As with the Beast of Alaya, the Beast of Gaia is Primate Murder.

The Counter Force born from all humans wants to survive even if it eats up their own planet. Our Counter Guardians start acting up only when a situation is already happening; the instant a factor that can destroy the world starts moving, they come to annihilate that factor.

The Counter Force itself is a swirl with no shape or body that will adjust its structure in order to definitely exceed the target and erase it. Usually, the Counter Force will boost up an "ordinary person" to remove the factor of destruction, and thus, create a hero. A human who has become a hero thanks to the Counter Force will be added into Alaya after death.

As it has no consciousness, it can't be witnessed and people don't notice it consciously.

Beast of Alaya
The Beast of Alaya is the Counter Force born from Alaya, the Counter Force of humanity: the Guardians, the Heroic Spirits.

They defend humanity from destruction. But when humans themselves are the cause of their own ruin, then the Guardians will kill everyone around when they are summoned in order to save humanity as a whole. Heroes are no exception and can become their target.

Beast of Gaia
The Beast of Gaia is the Counter Force born from Gaia. It protects the celestial body called the Earth from harm. The Beast of Gaia is the Dead Apostle ranked first in the 27 Dead Apostle Ancestors, Primate Murder. It moves when an external factor threatens Earth with destruction.
