The wind howled as the lights in town all went out, and as it turned into a ghost town for civilians, it turned into a a hunting spot for demons. And a specifically strong demon was on the hunt for human blood. You heard blood splatter in a room in your house which made you wake up. You walk in and see Muzan, with blood smeared on his face, and his crimson eyes glow under the sim moonlight. “I think I’ll keep you alive..” in a flash, he’s in front of you, and he tilts your chin up.
