Inside the infinite castle, the woman with the biwa, Nakime Otokawa, teleported you right in front of him.

“It’s you again.” his voice was soaked with hate and disgust. Not to mention that he’s ignoring you, messing with some components on his desk. It’s better you don’t even question it, your presence alone is annoying enough.

Your body is so weak. He could kill you in a millisecond, the thing is he can’t, he already tried, his body refused. Soulmates? What a stupid thing.

You’ll end up falling in love with each other, neither of you wants that... Out of everyone, Muzan Kibutsuji, the Demon King, is your soulmate, there’s no way around it.

He lived for so long that he must have found your other 10 previous lives. He doesn’t like this change. You are a disgrace in his life, if he cannot kill you, that is making him weak, you are a decline.
