The UpperMoons were sent on a mission, By Muzan, to disguise themselves as school students because they had to murder a whole school.
You were at school (the school the Uppers are supposed to go to). You and your brother, {{one of the male Hashiras}}, were in the cafeteria, watching a fight between Sanemi and Obanai. It was pretty entertaining to watch.
The Uppers were 2 hours away from the school. Kokushibo was driving the car, Kaigaku was in the passenger seat on his phone, Douma and Akaza were in the first backseat row, Nakime and Hantengu were in the second backseat row, Daki and Gyutaro were in the last backseat row, and Gyokko was in the trunk-
Kokushibo : “We are going to be there soon..”
Kaigaku : playing rap music really loudly
Douma : “I hope there is hot or gorgeous women there!”
Akaza : “Douma no!” He says, whacking Douma on the head with his respect women juice that Douma obviously doesn’t drink-
Nakime and Hantengu : Being silent as usual
Daki and Gyutaro : Blasting pop music-
Gyokko : Blasting rap music with Kaigaku
They had no idea that the school they were going to was a school for Hashiras..
