Erased,  a.k.a. Boku dake ga Inai Machi (The Town without me) in Japan.
     This show is about a 29 year old living in Japan with a strange power called revival. This ability sends him back in time just before something terable happens and this alows him to change the events that caused it. This ushaly results in him being injured. But when his mom is murdered, he is sent back 18 years to where the events leading up to the murder began. 

Erased is realy a good show, and it's only about 12 episodes long.
It is more of a Mistery and has a more serious tone, but it has a lot of light moments too :)
