Satoru Fujinuma is a 29 year old (in 2006) manga artist who also works part-time as a deliveryman at Oasi Pizza and the main protagonist of the series. He possesses an ability called "Revival", which would bring him back to a time before a life-threatening incident has happened and allow him to prevent it. When he was framed for his mother's murder, he was brought back to 18 years ago when he was 11 years old (1988) where the same kidnapper has killed two young girls and a young boy in his hometown.
