There are now strong indications (including the ad poster below) that this will be a "2 kuur" (i.e., two season, or 24-episode) anime. This seems like a bad idea for an anime of this kind. One person on 2 channel posted that although he is a fan of the comic, he doesn't think it should go two seasons. We'll see. I love
Hidamari Sketch, for example, but 12-13 episodes is definitely going to be enough.
I don't know if this has been posted here before, but there is an English advertising poster for the anime. I
guess it's genuine. The English advertising suggests to me that KyoAni may be aiming for quick international licensing:
I suspect that voice-recording is already underway, so I hope they made the decision to go 24 episodes based on the excellence of the first couple of episodes, lol.
