Satoru Fujinuma is a 29-year-old who works part-time as a pizza deliveryman in order to make ends meet due to his unsuccessful career as a mangaka. But there is more to this struggling adult than meets the eye, as he possesses a mysterious ability which takes him back in time right before a life-threatening incident occurs. When “Revival,” as he calls it, triggers, it will continue to send him back again and again until he is able to save the lives of the individuals involved.
But Satoru’s life is about to take a turn for the worse when a loved one is killed by an unknown man and he is framed for the crime. Desperate to get away so that he can assess his situation, he is inexplicably sent 18 years into the past—right before the disappearance and death of his classmate, Kayo Hinazuki, an event that has plagued him since childhood.
Satoru, now an elementary school student, must get his wits together and save the young girl from an untimely demise by figuring out the identity of the person responsible. But just how is Kayo’s murder connected to the present?
