Reliving the past - Kokushibo x Reader -ONGOING-

Kokushibo x Reader - MANGA SPOILERS!
Kokushibo, also known as Michikatsu Tsugikuni who's been a demon slayer himself before turning into a demon. His life as a human was as happy as a man could wish it to be. His wife was the source of his happiness until everything has been taken away from him because of an incurable illness his wife suffered from.

He lost everything and he promised himself that even if it took thousands of years, he will find the soul of his wife again. That's why he accepted the demon king's offer to become a demon over 500 years ago.

He was beginning to lose hope until one day he had finally found her. His beloved (y/n), more than 500 years later. A woman in her 20s who looked exactly like Kokushibo's long lost wife. She was her reincarnation.

But how will she react when he tells her?
