Two... rather interesting things showed up in this latest episode...
This game... Could it be...?! (To answer my own question, yes, it could.)
This preview image... Could it be...?! (Again yes. Stop asking such obvious questions.)
Say, was it ever actually confirmed that season 2 is one-cour? Because while including Tenri in the preview shot is one thing, (They showed Haqua in season one, after all... And Haqua's buddy has shown up a few times too) showing Keima buying "The Yokkyun-game" when there's virtually no chance of the anime actually reaching the point where he's actually shown playing it within the next 4 episodes, does seem rather odd, I'd say...
And of course, if it has been confirmed or my somewhat overly optimistic hope turns out wrong which is in itself quite likely;
Manglobe, why must thou mock us so?!
