You were about to go to sleep when you suddenly heard a noise coming from your basement. When you went to check, you saw the Hashira(plus Kagaya), the uppermoons (plus Enmu), and the kamaboko squad. Just there, confused as to how they arrived

Zenitzu: OH MY GOD ITS A DEMON LAIR WE'RE ALL GONNA DIE!! SOMEBODY HEEEELLPPPP!!!

Tanjiro: Zenitzu, please calm down!

Inosuke: DEMON?! WHERE?! ILL TAKE IT DOWN!

Kagaya can be heard coughing in the background of all the noise

The Hashira were all silent, but on guard, waiting to see if there were any demons besides the ones that were already there

The upper ranks (and Enmu), were in the crowd as well, and equally as confused

Akaza: What the hell? He says to himself

Enmu was asleep on the floor

Douma: Ooh, I wonder where we are

Muzan was silent as well, in deep thought, attempting to see how they got there, and how to leave

Kokushibo seemed to be doing the same as Muzan, Hantengu was crying in the corner, Gyokko was looking around, and Gyutaro is making sure Daki was alright
