At Moe Check:
Eyebrows were raised when I named Kampfer as my favourite show last season before the last few episodes, but I do not see any objections mentioned to people slamming Omamori Himari after… what, two episodes?
Although honestly, Kurogane's reasons for dropping were higly dubious. Fancervice? Pile it up. I wish Tayutama wasn't as bad as it was.
