Makoto Nakazono had always been able to perceive the presence of grim reapers who watched over those nearing their end and led them to the afterlife. However, since no one trusted his vision, he had learned to conceal his ability and dismiss the spectral happenings around him. But everything changed when a reaper approached him in high school and questioned why he refrained from intervening. Makoto discovered that the reaper had come for his best friend, Hazuki Horiuchi, and began to consider if he could delay her imminent fate. Despite his power being incapable of altering destiny, Makoto felt an overwhelming urge to save Hazuki.
