The story centers on Lich Arklow, one of Banica's loyal servants and a former forest spirit that was introduced in previous installments.

Meanwhile, the King of Lucifenia, Arth, Lich to investigate the sudden appearance of the Undead Soldiers known as "Outlaws" that have mysteriously appeared in the south, souls that haven't been able to move on because their bodies haven't died.
The story explores Lich's past in the Second Period and his relationships from then and now, while expanding a little on the various "endings" and alternate worlds presented in master of the heavenly yard.
This story contains examples of:
- Call-Back: The series brings back the undead soldiers from Judgment Of Corruption which Lich insisted weren't related to Banica.
- Calling the Old Man Out: Amostia, the boy of destruction Seth created that Nemesis based Punishment off of, has gained a will after the end of the world and he makes clear that he is not happy with his creator for never making him a sister, and for being a lying evil scientist in general.
- Day in the Limelight: The story is exclusively from the point of view of Lich, Arth, and Seth, and features mostly minor characters.
- I Choose to Stay: Quite a few souls are unsure about going into Allen and Riliane's new world, and instead remain in the destroyed remains of the Third Period. Arth in particular decided to stay to lead these remaining souls.
- The Reveal: A really early one is that the man on the cover dressed as Keel Freezis is actually Seth Twiright, who tried posing as Keel to be allowed to tag along with Lich.
- Save Scumming: Discussed; Seth speculates that Sickle was able to give Allen the knowledge he needs to save their world by merging him with an Allen of a parallel failed timeline, and compares it to Hazuki's motto of restarting from a save point.
- Self-Made Orphan: Seth reveals that he shot and killed his mother in the Second Period, supposedly to help her "understand" what he was thinking.
- Stealth Prequel: To the Torture Tower Never Sleeps series, explaining how the world of that series was created and where "Amos" of that story came from.
- Undying Loyalty: The last chapter reaffirms Lich's desire to literally follow Banica to the ends of the earth because of how deep his respect for her is.
- Unexplained Recovery: After being eaten by Banica and explicitly spending the whole series being inside her stomach, the Demon of Gluttony appears in the final chapter without a clear explanation of how he got out.
