Studies must continue even in tough times like these. UA students and remaining teachers have been offered hospitality by shiketsu high. They'll have some classrooms available and a place to train their quirks.

First day, they might end up getting lost in the hallways but that's just reliving first day of school in UA. I believe future heroes will manage it.

Journalists have been pushed away not to bother students and current priority is getting lives back in normal... although nothing wil lbe normal until New Era is completely defeated.
