Okay, so I did a little investigating. First I checked the
anime main site, hasn't been an update since that OVA last year. So I raided their
twitter page, and the recent post appears to be April this year, and one of them talks about the
Pos X Pos volume 2 collection (NSFW no bra girls), which is the 5 IS girls in pajamas. If the image in
that link is for reals, that should make it Pos X Pos volume 3, but where's the bleeding announcement? Was that a zealous retailer 1 month ahead of schedule?
