I watched episode 1 (with subs) today, and I really enjoyed it!
I admit I only watched it because I heard Mayu does more than just appear in the OP and ED, but really enjoyed the whole thing. Milk Planet are a kind of in-show idol group, and do some narration as well, and appear in episodes too. The song is really good and I want to support them like a real idol group!
Owada Nana is the lead and is just too cute. I don't particularly like Juri and Kawaei's characters so far, but Juri's is warmed up a lot to me as I thought it might. And she is really kick-ass at killing them zombies. It's really funny how they've done the zombies and what they do during the episode, too.
Overall, the show is kinda what you expect from an AKB school drama, but with the added amusement of the zombie slaying. I'm really looking forward to watching episode two with subs, especially since I know there's a bath scene
