Court of the Immortals (completed)

(completed)
(Female) y/n Hyakuya x Crowley Eusford reader (Male)
btw y/n is around 23 for guideline reasonings.
The existence of the earth we once knew has crossed from fighting against the vampires to being taken over and fully emerging into the full control of immortal undead beings. It's impossible for there to be a higher emotional state than hatred and mockery between the living and non-living aspects of the place we live in? It's prohibited.
