It's you

Lee, the last and final victim of the infamous serial killer known to kill little girls, or so we thought. He strikes again when Ms. Fujinuma gets onto his tail and comes close to finding out who he was. Killing Ms. Fujinuma was just the beginning though when Satoru Fujinuma walks in at the wrong time to find his mother's body laying still on the ground, and when you think things can't get worse his next-door neighbor comes by thinking Satoru killed his mother called the cops on him.

Now Satoru was on the run until he ended up having a "Revival" that had taken him back 18 years into the past in 1988. Now that he was in the past he wanted to save every last victim killed by Gaku Yashiro, but to do that he must gain the trust of every victim, including Lee. Will Satoru be able to save Lee and the rest of them? Will Satoru ever find out that Gaku Yashiro, a man whom he once looked up to was actually the killer the whole time?
