Erased (2017)

Kei Sanbe's manga gives its time travel one strict and personal rule. Satoru Fujinuma, floundering through life at 29, is thrown by a "Revival" eighteen years into the past, back to his childhood, with a chance to save Kayo Hinazuki, the girl who was kidnapped and murdered when he was a boy the first time around. Because he only has a child's freedom to act, every change costs effort and nerve, and the mystery of who the killer is runs alongside the question of what changing the past does to the present. It is the most suspenseful entry here and the one where the stakes feel most personal. Yen Press publishes it in English.
