I don't mind if you bite

in the principal's office

Principal Ubuyashiki looked at them in disappointment "Why were you guys fighting?" "he changed me to a fight!" "ok, tanjiro why did you change him to a fight?" "I did not change him, I just said hi and he pushed me." "he did change me!" Inosuke says defending himself "no I didn't!" Tanjiro retorts back "yes you did!" "no I didn't!" "yes you did!" "no I did not!" "Did to" "did not" "well since we can't settle on anything you both be in trouble" Principal Ubuyashiki says leaving no room for arguments "but-" "no, the both will be getting detention, gyomei please take them to the detention room".
They both followed gyomei to a room that was about the same of a class room "ok you guys will have to stay in here for half an hour so please Don't fight each other".
