Akari is a "Lost One," a person isekai'd from Japan and who through the process ends up obtaining a reality breaking power attached to their soul called a "Pure Concept." Akari's Pure Concept is "time" and her initial ability allows her to regress things to a previous state. This ability can automatically trigger upon death and revert her body and mind back to a safe healthy state before what caused her death.
Upon meeting Menou, Akari feels that it was fate that they met and with only minor convincing by Menou ends up going along believing she will be taken somewhere safe by accompanying Menou. Menou finds the extreme degree with which Akari trusts her to be abnormal.
