You were running late to class so you were quickly walking down the halls, you saw your History teacher (Rengoku) walking toward the door so you quickly ran to the door, opened it, and sat down in class, there you saw your classmates Tanjiro, Zenitsu, Inosuke, Muichiro, and Genya (All of them know you) (Nezuko isn't in this, she's just at the butterfly mansion I guess-) (Your History teacher is Rengoku, Math teacher is Giyuu, English teacher is Tengen, and Science teacher is Shinobu)

Tanjiro: I see you're running late again, you need to start waking up on time-

Zenitsu: Don't act like you've never been late before, Tanjiro!

Tanjiro: I really haven't-

Inosuke: Shhhh! Let them speak-

Muichiro: You're way too defensive, Inosuke...

Genya: he didn't care, he was just blankly staring at the whiteboard wishing he could go to lunch
