This is an information chapter about his Heavenly Restrictions.
1. Enhanced Physiology
Rein has a superhumanly gifted body, making him MUCH stronger than a standard supernatural being physically.
Tradeoff:
Rein possesses zero Cursed Energy.
2. Temple of Time
Rein can activate the Temple of Time once every 24 hours. When used, his left eye allows him to see two hours into the future, either his own future or someone else's. The future he sees is near-perfect, but not set in stone; his actions in the present can still change it.
Tradeoff:
His right eye is permanently missing. Even if the eye were replaced or reconstructed through supernatural means, vision in that socket would never return. For this reason, he wears an eyepatch to conceal the absence of his right eye.
3. Essence Protection
Grants existential protection by providing near-absolute immunity to attacks targeting his soul and mind.
Tradeoff:
No supernatural healing can regenerate Rein's physical wounds. Only his own body's natural healing and regeneration can repair damage. Non-supernatural methods, such as medicine or surgery still work normally. The only way to fully circumvent this limitation is through the immortality gained via Enlightenment.
4. Erasure(inspired by Pochita's Devil erasure)
By consuming the heart, or whatever serves as a being's true core, Rein can permanently erase the target from existence.
If the target is an embodiment of a concept (such as Primordial Gods, or even Devils from the CSM world), their erasure also removes the concept they represent from reality.
Tradeoff:
Each successful use of Erasure consumes five years of his lifespan permanently. Moreover, his lifespan cannot be increased or restored by any supernatural life-extending means (except Enlightenment).
