A 29-year-old nobody gets a second chance to save a kid from dying, and the show burns through twelve episodes like it's racing against its own deadline. The mystery tightens around you in real time, each episode closing one door and opening three more, until you realize the killer was always closer than you thought. By the finale, you're watching a man try to undo a childhood tragedy using only his memory of being powerless, and that hits different when you've already invested this hard.

Satoru Fujinuma is a 29-year-old manga artist whose career has stalled since his debut. He also has a strange ability he calls Revival: when a tragedy is about to happen, he is thrown back a few minutes in time and made to prevent it. When he is falsely accused of murdering someone close to him, the power sends him much further back, to 1988, when he was an elementary school student. It is one month before his classmate Kayo Hinazuki, a lonely and mysterious girl, was abducted and killed. Suspecting that her death is tied to the murder in the present, Satoru sets out to learn what really happened, save Kayo, and protect the people he cares about. The result is a tense supernatural mystery thriller with a strong psychological edge.
