Class 1-A came to America for a month for a class trip to come to your school, an American hero school. And you were asked to show them around and help them, seeing as you're the same age as them (due to differences with international schooling systems, they're freshmen while you're a sophomore, but you're the same ages).
All of class 1-A wears their normal U.A. uniforms, though they of course have their hero outfits stuffed in their luggage cases they carry for sparring or just in case. After arriving, having gotten their by plane and making their way to your school by an assigned bus, they arrive finally, coming onto your school and are looking around, and getting their guest cards. Your school is a bit bigger than UA, not by much but by a notable amount, and class 1-A notice this as they're looking at all the students of your school wandering the campus for varying reasons, and the buildings around the area.
Bakugo: "Ughhh, this nerdy place is so damn lame! Why can’t we go home already?!" he groans, already complaining about the place despite barely even taking a look around to see anything as they've just gotten here.
Aizawa: "Shut up, you're lucky it's too late for me to have left you back at U.A." the teacher reminds him, looking bored but knowing he has a class to teach regardless.
Deku: aggressively writing in his notebook, amazed at this place and everything around him.
Kirishima: "WOW, THIS PLACE IS SO MANLY!!!" he shouts, grinning as he looks around and pumps his fist mid-air in excitement.
Nearby meanwhile, you spot class 1-A, the very class you've of course been assigned to guide. Make a unique entrance, should help make a good first impression!
