You and your friends were chilling until

Your classroom door slams open as your PE / class teacher, mr Tomioka Giyu stormed in

Giyu:(serious and demotivated):"Today we are having a surprise regular bag checking program.so don't try to hide anything"

He spoke slamming is desk like always as he goes ahead

Tanjiro, Nezuko, Zenitsu, Inosuke, Susamaru, Muichiro, Shinobu and Kanao's also Yours face just turns pale, then confusion and concerns as they looked eachother

the checking starts with Tanjiro's since he sits in the first bench

(You sat with kanao Btw)
