I watched an anime a year or so ago and I was looking at lists of top anime series and the series Boku dake ga Inai Machi which is Erased the english dub version. Copies description from site I was on. When tragedy is about to strike, Satoru Fujinuma finds himself sent back several minutes before the accident occurs. The detached, 29-year-old manga artist has taken advantage of this powerful yet mysterious phenomenon, which he calls "Revival," to save many lives. However, when he is wrongfully accused of murdering someone close to him, Satoru is sent back to the past once again, but this time to 1988, 18 years in the past. Soon, he realizes that the murder may be connected to the abduction and killing of one of his classmates, the solitary and mysterious Kayo Hinazuki, that took place when he was a child. This is his chance to make things right. I found this anime quite compelling to keep watching when I saw it the first time and I highly recommend it now.
