Satoru Fujinuma is the main protagonist of the series. He is a 29 year old (in 2006) manga artist who also works part-time as a deliveryman at Oasi Pizza who possesses an ability which he calls "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 kidnapper has killed two young girls and a young boy in his hometown.
Satoru is a fair-skinned man in his late 20s with messy navy blue hair and eyes, a slim figure, and a tall stance. He often bears a blank expression and rarely smiles. He is most often seen wearing a white polo shirt, black pants, and a pair of loafers in the same color in addition to his maroon-colored prescribed glasses due to his eyesight loss as his age progressed.
When he was younger, Satoru had better eyesight and habitually smiled more often. He was of average height for children his age and wore a two-toned brown windbreaker above a light blue tee, dark pants, and navy blue rubber shoes.
