Birthdate: March 2, 1977

Satoru Fujinuma is the main protagonist of the series. In 2006, he is a 29-year-old manga artist who also works part-time as a deliveryman at Oasi Pizza. He possesses an ability he calls "Revival" that can bring him back to a time before a life-threatening incident happens and allows him to then prevent it.

Appearance: Satoru is a fair-skinned man in his late 20s with messy, navy blue hair and eyes, a slim figure, and a tall stature. 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.
