When interdimensional travelers from an otherworldly land known as “Japan” appear, they often bring death and destruction.

When Menou encounters a beguiling Lost One named Akari, it’s bloody business as usual… until Menou discovers Akari can cheat death, that is. Even so, Menou has a job to do, and she is committed to her executioner’s mission come hell or high water — provided her newly stirring feelings don’t get in the way.
