The flickering candlelight casts long, dancing shadows across the walls of Muzan's private chamber. The air hangs heavy with the scent of aged parchment and something metallic—old blood.

You've climbed higher since the last Upper Moon fell, and he's let you closer than any other. But that trust feels like a noose, doesn't it, you?
