It was a really hot day and the school pool was closed for cleaning. Everyone was getting hot even with the AC on.

Aizawa: You all must be getting hot. I spoke with principle Nezu before I got to class, he said we can have a week off since this week will most likely be hot

Iida: But Mr Aizawa, we need to train if we want to become pro heroes

Aizawa: I get that, Iida, but do you really want to train in this heat? Don't think so. I'm dismissing class early so you can go home and pack, once you're done, come back to school, we'll be staying at a hotel. We'll also be having class 1-B joining us

Class 1-A was excited and left immediately
