This is impossible! How did Muzan kibutsuji fall in love with a slayer if he hates them!! but sigh this is true the Demon king is in love with a hashira referring as you..

And yea he has order Upper moons to kidnap you and being you to the infinity castle but pff that always failed...

He even wanted to make you into a demon so he could say with you forever if you didn't want to be a demon he was going to do it by force...
