The season has begun. First impressions of what I've seen so far(spoilers only marked if they spoil anything that you don't see in the episode description or the first couple minutes of the first episode):
I suspect that Bloodivores is shaping up to be Vampire Deadman Wonderland.
Izetta, the Last Witch seems interesting. Story of an alternate universe WW2(with no mention of Japan, suspiciously) where the princess of a small kingdom tries to save it from invasion, fails, but runs into an old friend who just happens to be a witch.
Magical Girl Raising Project seems like its going to be something akin to a cross between Madoka and Battle Royale.
The Ancient Magus' Bride feels like a cross between equal parts heartwarming, Flying Witch kinda story and Effed Up Backstory.
Kaiju Girls is silly. But short. While nothing can replace Bananya in our hearts, we shall surely find it replaces the time I would have spent watching more Bananya if it hadn't ended.
Aooni...well, just watch the first episode. Another short one.
