Erased (Boku dake ga Inai Machi) is one of my favorite series so far this season.
It's a "Butterly Effect" themed series. The main character has the ability to time travel in a very similar way to Max Caulfield from "Life is Strange" - whenever something bad is about to happen, he can perform a "revival" and travel back to moments before whenever the cause of the event began.
The pacing is excellent. The characters are interesting. There's a big murder mystery element to the story. It has a similar but more serious tone than Steins;Gate.
I very, very highly recommend watching this one. As of the time of this post, there are seven episodes out on Hulu.
