Revival (再上映, Ribaibaru, lit. "Rerun") is an involuntary special phenomenon exclusive to Satoru that allows him to jump back in time in order to rescue someone from a fatal encounter within his proximity.
Satoru begins to feel a discomfort, before being brought back in time by a few seconds prior to a forthcoming incident. This allows him to seek out the source of discomfort and remove it in order to prevent further complications. However, this solely relies on his experience, as the cause is often oblivious. The event enables him to prevent people's deaths, hence the term "Revival". Empirically, Satoru's capable of responding to Revival, as it occurs involuntary and often at random times. Fujinuma described his experience as deja vu.
- In the midst of traffic, Satoru notices a runaway truck. He quickly catches up to the vehicle and manages to alter its path, saving a boy's life, but ends up hospitalized after sustaining non-fatal injuries.
- At the market's parking lot, Satoru informs his mother to look for anything out of the ordinary. Having noticed the two in the distance, a mysterious man holding a child's hand leaves by himself soon after.
- After discovering his mother's death, Satoru attempts to track down the murderer, who leads him astray into an alleyway, before being cornered by police officers under the suspicion that he tried to flee the crime scene. Satoru persistently attempts to turn back time, which triggers a large-scale Revival, bringing him back 18 years in the past.
- Having failed to prevent murders that occurred in 1988, Satoru's ejected into the aforementioned alleyway. A few days later, Airi restores Fujinuma's lost confidence, which later helps him to jump back in time again.
