I guess my impressions from the PV were right. I was beginning to get annoyed at JCstaff for making Yumekui Merry and then Hidan no Aria, both which were kinda "meh," IMO, but this was much better than both of those shows. There really is an odd "Denpa Onna"-feel to the show in the scenes Ayaka are in (Garden club scene, anyone?), but I think that's where the similarities end.
As far as animation quality, it's not super-high-budget-KyoAni-style, but it doesn't look overly cheap either. The weird ambient music suits the show, and the characters aren't all obvious cloned stereotypes of other characters; they have a bit of depth to them. There's minimal fanservice; it's not stupidly overused but it does add some humor to the show.
We could have a winner here if the rest of the series is as good as this first hour-long special episode. (I haven't watched Gosick or DRRR!, so I can't really compare them to KamiMemo)
And Catcher, there's always a KVM switch, or even better:
Synergy. :3
