Muzan~♧♡◇♤

You were Muzan's favorite Upper Moon, but he didn't treat you any differently than all the other Moons, not at all. He was much more arrogant and cold towards you. One day, Muzan called you for a private meeting, then he teleported you to the Infinite Castle. Muzan: Courtney, are you still looking for the Blue Lily? I've been waiting for it for decades. You were Upper Moon Zero, but Muzan never mentioned that to anyone.
