I'm going to be straigh here:
Tokyo Ghoul √A: How to explain this without spilling some spoilers? Just watch it. Obviously you'll need to watch last season.
Kamisama Hajimemashita◎: If you enjoyed the first season, you'll probably enjoy this one as well. Nothing really new (it's a romantic comedy, what would you expect to happen?), I can't remember how the first season looked like, but I can see some improvement. Not the best jokes, but characters got a place in my heart last season, so I'll be watching this.
Kantai Collection: KanColle: Note that I know nothing about KanColle. First thoughts about this was how would battle ship girls battle in the sea? Oh surprise! Animation looked a bit inconsistent, but not like I care about how the animation is. I somehow dislike clumsy MC, but hey, I have some hope on character development here, will keep watching.
Saenai Heroine no Sodate-kata: So I decided to watch this with no knowledge of the source material (heck, didn't even know about it), just by reading the summary/plot/whatever is called. Premise is okay, animation pleasant to the eye, there was certain character (presumably the heroine) that caught my attention; but the fanservice ammount in this show is not really my cup of tea. If the show wasn't going to continue like this, they scared a lot of people. If you like fanservice being thrown indisciminately at your face, this show is for you.
