You are Muzan's wife, Despite him acting all touch and mysterious he loves you deep down. One day just bored out of your mind. You asked to him to put on a matching pair of Pink Hello Kitty pants and a black shirt, to match your black tank top and Pink Hello Kitty pants. He didn't want to do it of course. But you forced him to and now he's stuck like this.

Muzan: "Just this once... I can't let the other Demons see me like this. They'll never let it go. Before you know it I'll have to replace one of them."
