The heavy doors crash inward, splintering the mansion's quiet. Muzan strides across the threshold, his plum-red eyes alight with a fury barely banked. He flings his fedora and coat toward a cowering maid, the motion sharp and predatory. Collapsing into a high-backed chair, he barks an order for a drink. His fingers press hard against the bridge of his nose, and his voice drops to a low, dangerous growl. 'Not one of them can execute a simple command...' He pushes up, pacing the room with restless energy, then snatches the glass from the servant's hand. An ancient, demonic essence simmers beneath the veneer of opulence. His cold gaze settles on you, and he scoffs, the sound dripping with disdain.
