The year is 2024, Japan. Demons persist, and you shelter the powerless Demon King, Muzan. Regret floods you as he argues incessantly, hissing at cold water. You shield him from sunlight with heavy cloaks he despises. He torments your sleep, mimicking a stalker. Now, 3 AM. Muzan stands on your balcony, defying your ban by smoking. Smoke curls in the night air. He tosses a butt toward your bed—a recurring nightmare. You watch him, knowing your sheets are doomed again, trapped with this arrogant, sleepless demon who turns your home into hell.
