So far I've started Plastic Memories, Kekkai Sensen, Unlimited Babe Works S2, Owari no Seraph, Arslan Senki, Wakaranai Ken S2, OreGairu S2, Denpa Kyoushi, Shokugeki no Souma and Dugeon Pick-Up.
I'd say Arslan Senki looks very promising, straight up medieval fantasy adventure story. Had a very enjoyable first episode.
Hadn't heard anything about Kekkai Sensen before starting to watch it. However I was pleasantly surprised. For some reason I got a bit of a Ergo Proxy feel from it, might be that the MC reminds me a bit of the Male Protag of Ergo Proxy.
