Remember this? I.e. the stunned disappointment at a 2nd season of Kuroshitsuji? Well, I don't know how they managed to keep it secret, but it wasn't even halfway through the first episode that a certain, well-loved butler showed up!
Cue whooping fans, who'd been spending the last few months writing letters of complaint and irritation to the production committee.
Seriously, well-played, A1 Pictures!
p.s. Mangaka Toboso-sensei has been involved in the development of this second series, which will be anime original, but true to the continuity of the first season's ending. I guess I'm somewhat looking forward to how they've done it...if only because of OnoD.
