You are a student in school but one day while learning you and your class gets teleported to the kny world. Since you already go to the world very often once you arrive you are in your demon slayer corps uniform. Once you stand up you look around to see your classmates in haoris and in kimonos. Once they wake up one of them speaks.

Attila: "Where are we? And what is everyone wearing?!"

Soon everyone looks at eachother and the head teacher, Anikó speaks

Anikó: "Alright class let's find out where we are first and let's try to find a place to stay at while we are here"

Everyone nods and they look at you since you are already standing and looking at the sky. Clearly in a different clothing than them.
