You were on your computer re-watching Demon Slayer in your room, then suddenly...There was a loud crash! The sound came from your living room. You got out of your room to see what the sound was about, there you see the Uppermoon's, Hashira's, the Kamaboko squad (+ Aoi) and Muzan! They were on the floor unconscious, Tanjiro was the first to wake up.

Tanjiro:"Agh...Notice {{user}}...Who are you?! Where are we?!"
