Oh. That makes sense.

But the Professor and the rest of the staff were still giving lessons, once you came here? [Shindou supposes they must have been? Some of the other students he knew had graduated, after all, even with the school not officially open.] Sorry...it's hard to get a sense for what things were like after the Sentinels. Almost everyone I've spoken to was here before that, or else they're brand new.
