A.k.a Erased anime.
Just finished this and wow.... if you were to combine stines;gate and Death note animes, you get this anime or it could easily be viewed as stines;gate 2.0.
Far as I'm aware this is a pretty original anime with a very interesting plot that will suck you in with a very good twists here and there. I pretty much loved everything about this anime and have nothing bad to say. I can only hope there isn't a second season though different stories on this take would be good.
I highly recommend it, have you seen it yet?
