Even if it's OVA, I sure as hell pray that it will not just be a one episode OVA!
Hmm...was there a case where an OVA series gets to 12 episodes?
I guess I'll just have to make due with low ep count.
Oh well, whatever, but if its OVA, we can expect some more quality! Actually screw that, I just want to see my Chihaya move damnit~!
Also, why did they have to change the cast if it's OVA? Doesn't OVA means it doesn't get broadcast-ed?
