After losing his fiancée to suicide, Itsuki Kisaragi devotes his life to saving others by patrolling the cliffs that claimed her. However, when a woman, Sayaka Usami, leaps and accidentally pulls him with her in a rescue attempt gone wrong, both awaken in a new world far different than their own. Reincarnated with the powers 'to hold life in one's hand no matter the pain', and 'to fray all danger beneath conviction', they're thrust into a conflict far grander than themselves. Now they must decide the direction of their new life, all while still coming to grips with their old.
