The song is sung by "The Servants". They demand that all bows to their great master, namely "The Master of the Graveyard". They tell that she was reborn as the "King of the Undead".
As intruders walk in, they are captured by the servants and the questioned by the master on how they want to be eaten. The servants then declares that the end of all is upon them, but they'll keep partying until that day comes.
Clockworker's Doll has been tasked, or atleast she believes so, to judge the living for their sins and send them to hell. She wonders if it's truly the right thing to do and asks her later "father", Gallerian Marlon, for guidence, saying that she can't understand anything, since she has no heart.
Gammon Octo, the gardener, is trying to warn her that the end is upon them and her actions will do no good but Ma agrues againts him and the doll, not knowing who to trust, keeps swinging the gavel without knowing what she's doing. She asks her father to help her once again, as she's uncertain that utopia will even be created.
Nemesis Sudou stands holding a weapon of mass destruction in her hands and is about to activate it. She plans to destoy the sin that was split in seven. Believing the world it inhabits to be hell itself, she declares herself "The Master of the Hellish Yard", an authority in the Levin religion that is meant to punish people.
Nemesis later reveals herself to have become a dictator with the intent to destroy all life on the planet. As she fires her weapon, someone mutters they they're all "sons of bitches".
