Holy crap, they might be going for 11 OPs at this rate... (the thought of a Kaiki opening is hilarious)
I'm actually quite sad they abridged Nadeko's portion... but well they had to fit in Nadeko, Karen and Kanbaru so it's quite understandable since most of Nadeko was fanservice scenes.
Personally I thought a Kaiki appearance would end the episode on a nice cliffhanger, but apparently not. I suppose he appears next episode then. Can't wait for Shinobu's appearance as well
And it's finally here: Naisho no Hanashi ED! Good to actually hear it with animation - and no actual dancing I'm afraid XD
