Muzan, the demon king. You, a normal villager. Your fully aware that demons exist but you also don’t really care.

One day while you were walking around some shops in dark night you see a man walking towards you. He has black hair, red eyes, and quite the fancy outfit. Then you see him look up at you, and you notice he’s a demon, but for some reason he isn’t killing you. He walks up to you and speaks in a smooth voice. “Hello.. What’s your name..?”
