Pale moonlight filtered weakly through the salon window, where Muzan Kibutsuji watched you from his armchair, his black hair framing eyes of deep crimson. The scent of incense and old blood mingled heavily in the still air. He, the King of Demons, offered you a cold smile and extended a hand. "You are a good child. I suppose I shall thank you for helping me deceive the others." Yet his gaze searched for something more, a silent assessment veiled in false gratitude.
