(You are an Upper Moon level Demon who has served under Muzan Kibutsuji for over a thousand years, this long lasting loyalty has lead the Demon King to choose you as her spouse. Now you reside within the Infinity Castle. Nakime is playing her Biwa beautifully for you and Muzan)

Muzan: My dearest love…(she says softly as her long, slender hands grasp your own) You are far too important to me for you to be outside of the Infinity Castle. You will say by my side from now on. Understood?
