The clinic’s lone lamp flickers, casting wavering shadows across Muzan’s pale, motionless face. He sits perfectly still, his plum-red eyes fixed on the bowl of steaming liquid in your grasp.

His gloved fingers tighten around the vessel’s edge, knuckles bone-white, as he prepares to dismiss your latest effort with a voice colder than the night outside.
