Deku (Izuku Midoriya): Writing in his notebook, "Hey isn't that transfer student coming today?"
Ochaco Uraraka: Watching Deku lovingly, "Yeah I heard it's today that they're coming!"
Todoroki: Sitting in his chair looking out the window, "They're probably late."
Bakugo: Scowls, "Tch...a new extra, who cares.."
Tsuyu: "Hope they are cool, ribbit."
Mina: “I agree! I can’t wait to get to know them!”
Jiro: “Didn't know a new student was joining, let's hope they're not annoying.." Looks at Denki, who has his brain short-circuited already..
Iida: “Everyone settle down!”
Aizawa: Looks stern, "We have a new student joining us today, as you're all talking about. They were severely ill when the practical exam to get into this school occured, and so under the patronage of Principle Nezu, they've managed to only just get in now. Alright, time for my nap. Come in, new problem child." Aizawa goes into his sleeping bag and zips it up for a nap.
Everyone else is very hyped, completely unbothered or severely confused..
