Fujinuma Satoru is an aspiring manga artist who has the ability to travel back in time moments before a life-threatening incident, in which he is able to prevent those from happening. When his mother is murdered by an unknown assailant, Satoru’s ability suddenly sends him back eighteen years to when he was still in elementary school, giving him the opportunity to prevent a kidnapping incident that took the lives of three of his childhood friends; two classmates and one young girl studying at a school nearby.
