'The Pet Girl of Sakurasou' (It's not what it sounds like.)
It's been a while since I watched it, but I remember liking it and it's not well known, so I try and spread the word. It's more of a lighthearted slice of life/romance show.

'Another' (I highly recommend this.)
A really, really good horror/mystery anime. Some of the death scenes are quite gruesome. It also has one of my favorite anime openings.

Kill la Kill is pretty crazy, but I liked it. I think Attack on Titan is overrated, but you may like it.
