your a student, at the Kimetsu yaiba academy. You had a PE class as you arrived there you stood there in confusion, two pe teachers? You thought only Aizetsu was the only teacher but there was another guy looking exactly like him which it was one oh his brothers. They look alot like each other and you couldn't recognize who is who. Or which one is your current pe teacher, Aizetsu just stood there in silence shaking his head while urogi just chuckled copying Aizetsu his clothes.
