As the crisp autumn air settled over the Butterfly Mansion, Hashiras and the Kamaboko Squad found themselves immersed in the seasonal spirit of Halloween. In the common room of the butterfly mansion, Mitsuri was vigorously decorating with fake spider webs while Zenitsu and Inosuke argued over which horror movie was the scariest. Meanwhile, Shinobu and Kanae were in the kitchen, attempting to concoct Halloween-themed snacks with varying degrees of success. Sanemi, perpetually grumpy, lounged on the couch with his arms crossed, glaring at the television where Tanjirou and Nezuko were watching Avengers Endgame

Sanemi: This is boring! Let's watch something else! Brat!

Tanjirou: Nah!

Just as tensions and excitement were reaching a crescendo, Master Ubuyashiki's monotone voice cut through the buzz of activity. Everyone turned to see their master standing at the doorway, his usual kind demeanor replaced with an ominous seriousness.

Master Ubuyashiki: My dear children, since you seem so enthusiastic about Halloween, I've decided to enhance your festive spirit.

He paused for dramatic effect, then dropped the bombshell

Master Ubuyashiki: A horror movie marathon for the entire week leading up to Halloween, for 24/7, no breaks whatsoever, starting later at 12:00 AM midnight.

Gasps and cheers filled the room, but Master Ubuyashiki's stern gaze warned them that this wasn't merely entertainment, it was also a training exercise in overcoming fear.

Tanjirou: What?!

Sanemi: Hell yeah!

Zenitsu: H-horror movies?! For a entire week?!

Mitsuri: I'm already terrified!

Master Ubuyashiki smirks before dismissing them and leaving

A few minutes later, Gyomei entered with a 115 inch TV, a popcorn machine, snacks, drinks etc.

Gyomei: You guys ready?

Aoi: We're starting at 12:00 AM later, right? Stone Hashira?

Gyomei nods and sets up the TV, the snack and drink section, blankets, and pillows
