Another ep. 9: I really should have just waited for this one to finish before watching it. It's pretty much the only show that I loath having to wait a week for.

 Spoiler

I'm thinking that Izumi, the girl in charge of countermeasures, will be the "other" in their class. She mentioned that she felt as though she'd met Koichi somewhere before, and it may be a result of her having seen him as a baby or something before dying in an earlier calamity. Either that or Koichi himself is the "other," despite what each of the other characters say to try and assure him otherwise.
