From time-to-time, Satoru Fijinuma, a 29-year-old hopeful manga artist, finds himself
propeled through time in order to prevent tragedies. Usually, these are short trips in time,
but when his mother is murdered, Satoru finds himself back at age ten where he must change
things to prevent the far-future murder of his mother and the present-day murders of his
classmates.
The eight-volume English version of the manga appeared in 2017-18 with the
title Erased.
I'm afraid. . . of digging deeper into myself.
