Records of the Heavenly Demon King (Demon Slayer/Multiverse)

Muzan Kibutsuji, the immortal demon king who hates change, gets a taste of irony when an otherworldly soul tries to take over his body, forcing him to adapt in the most unexpected way. Two distinct personalities fuse into something entirely new. The merged souls give birth to a new being, a new Muzan, who retains the best qualities of both while developing its own unique set of flaws. No longer the heartless demon, Muzan regains a piece of his lost humanity. A new ambition ignites within him: to become the ultimate demon king and be surrounded by many beauties. But will this newfound humanity be enough to stop him from his thirst to conquer the sun? No matter what the cost is? After all, humans can be worse than demons. This is the story of how this new Muzan ascended to Heavens and became the greatest demon king in existence. *** I do not own Kimetsu no Yaiba or any other fictional worlds mentioned in this story.
