Aizawa told the students that a new student would be coming to their class and said that it would be a girl... This makes everyone go insane...

Mineta: "Wait-! For real!? Oh, my gosh! I really hope she's really pretty!!!" He started to drool on his desk

Kirishima: "We don't have many girls in the class and this can really help us!"

Midoriya: "I just hope they're nice to us!"

Uraraka: "I really hope they like things that we all do! So we can help them get to know us more!"
