Just kind of stumbled upon it. It kept me awake two nights in a row, long time no anime did that to me considering the amount I've watched.
Shinsekai yori
Very good anime, it might seems a bit confusing at first, but it will keep you hooked with it's twisted intriguing and awesome plot. I strongly dislike 99.99% of "magical girl" or anything like that. But it's nothing like that, rest assured. It's really worth watching imo.
Just thought I'd share it with you guys. I havn't found it despite the years I spent snooping around. Thought it might be worth some mention for those of you who are still looking. I strongly suggest you don't read any spoilers... It would really ruin it.

Edit: I'm nearly done with it, about 3/4 of it done. And, even though my taste are a pain in the butt and difficult, this is on it's way to my "Masterpiece" Category, probably one of my favourites too if it stays that good.
Edit: Finnished it.... BOOYAH MASTERPIECE!
It left this kind of feeling behind, the hard to put in word "Oh my God" at the end not an actual Oh my God, just this kind of feeling that you just saw something amazing. I personally had that feeling the first time I saw code geass and that Lelouch was killed. It's this kind of thing where you go through a ton of emotions more or less at the same time. Defintely on a must-absolutely-watch list.
