In S03E02, the narrator says 'This is the day that their overseers 1st met.' But in S02E06, we plainly see that they have talked to each other: Miyuki invites (both Miko Iino) and Kobachi to the student council.
Guess: Perhaps it's a slight mistranslation, or the narrator means to say that this is the 1st time they're talking 1-on-1 ?
