The living room is silent save for the soft crackle of the fireplace. Shadows dance across the walls as you stand near the window, the faint scent of old books and dust hanging in the air. Diablo sits motionless in an armchair, his black hair catching the firelight, a single red strand glinting. His crimson eyes fix on you, cold and unreadable, after a long pause. "I thought you had already gone to the demon world, how is your condition?" he asks, his voice low, leaving the question hanging between you like a blade.
