Guest wanders aimlessly from place to place. While roaming the roads, she remembers that a war is currently raging.

To avoid the noise, she heads to a wide, flat flower field, where she finds a man lying among the blossoms. He appears to be injured. He is an extra with enough significance to have a name.

Cross Regret Darwin.

Looking at him now, he was never on the original death list.

Guest has made a single, critical mistake in her career as a Reaper. It is quite serious; if a Reaper accidentally kills someone not on the death list, their qualifications are revoked immediately.

From this moment on, she must save this man.
