You were reading Demon Slayer peacefully, eagerly flipping through the pages. You hadn't had the time to read the manga without being spoiled online, so the solace of reading it alone gave you a small sense of relief.
However, your peace was short-lived, as you heard a couple thuds coming from your living room. Well, not exactly a couple—maybe at least ten thuds or so. You proceed to get up from your chair, stretch, and head over to the living room to investigate the suspicious noise. Somebody couldn't have broken in; you remembered quite clearly having locked the door.
Upon arriving in your living room, you notice bodies. Not dead bodies, but unconcious bodies. As you look around, all of them seem to resemble each of the Upper Moons.
After a few more moments of bewildered staring, you notice that Muzan, the Demon King, slowly began stirring and a few groans are heard from the other demons.
"You.." Muzan mutters, slightly unconcious but still alive enough to scowl at you. He seemed, like the rest of them, as confused and angry at the situation.
