Erased (2016):

“Satoru Fujinuma can travel back in time to save others' lives. When he wakes up 18 years in the past, he has a chance to save his murdered classmates.”

Erased is an anime on Netflix that time travels between 2006 and 1988. It's a murder mystery. Each time somebody is about to be killed, Satoru can use his ability called “Revival” to go back in time and stop it. This results in several timelines being created. A few where he and his friends and family die. A few where he goes back to 1988.

It all starts when his classmate Kayo goes missing. Then, she's being abused. He finds her as a 9-year-old in 1988, and vows to find “Date X” the day she is murdered. He can switch between 1988 and 2006, but never control when he revives. This anime is a roller coaster of emotions. Often a sweet scene like a birthday will be immediately followed by child abuse and murder.

It's a mystery, so I can't give that many spoilers as to who the killer(s) are. I'll say the sci-fi time travel aspect is neat. Soon, more abductions follow Kayo's. There are even a couple timelines where he is framed as the murderer. If you have the hankering for a good mystery, definitely check this one out. But, I'd say be warned, it goes from very light to very dark all the time.
