- "Now, repent."
- ―Nemesis Sudou[src]
The song begins with Nemesis Sudou approaching a man and pointing her gun at him. She thinks of her mother as she recalls all the events that led to her seeking revenge against the man. Saying goodbye to "Mr. Pere Noel", she offers him the choice of dying by the fire burning the house or a gunshot. Nemesis then proposes he give back his entire fortune to be spared, only for the man, Gallerian Marlon, to snap that he wouldn't do so. Thinking back on her childhood, Nemesis notices the man comforting his Doll and declares him mad, remarking on how the man's true daughter died long ago. Bidding her father farewell, she wonders why her mother loved such a man as she prepares to shoot him.

Conceptualization and Origin
- Nemesis is the goddess of vengeance in Greek mythology.
- The term "muzzle" means gun point, referring to the open end of a firearm's barrel; interestingly, the term "gunpoint" means to threaten someone with a gun.
- The song's English title, "Satan's Revenge", is a reference to Satan, the patron demon of Wrath; it also refers to Nemesis' act of getting revenge on Gallerian, as portrayed in the song.
- When first concepting the song, mothy had planned for the story to portray the entire life of its central character, Nemesis, but realized later on that the song would be too large; he also admitted the issue caused a delay in the song's release schedule.
- While commenting on the song's creation, mothy stated that it was a process of trial and error and that the final song was nothing like the initial version, having eventually decided it was too bloated and cut down on its content.
- Prior to the song's announcement, mothy posted a poem entitled "Nemesis" with allusions seemingly reflecting characters, places, or events in the Evillious Chronicles; at the end of the poem, mothy stated it was a late night work and didn't have any meaning.
- On twitter, mothy posted a twit sound titled "the muzzle of a gun" for a period of time, featuring an instrumental sample for a future song; despite the name similarity, the sample itself used a different instrumental from The Muzzle of Nemesis.
- The revolver used in the song PV is based on the design of a Colt Python revolver.
- At the beginning of the song PV, a timeline involving the birth of Hänsel and Gretel, the Levianta Catastrophe, and all the major events involving the Seven Deadly Sins leading up to the song is rushed through.
- Like the other songs in the Seven Deadly Sins Series, the song begins with the phrase "さあ" (Saa) after the singer addresses the "sinful man" following the timeline sequence.
- Towards the climax of the song PV, the screen flashes phrases and images related to other songs; the phrases include "And Then the Girl Went Mad", "Abandoned" twice, "The Last Revolver", "Judgment of Corruption", and "Master of the Hellish Yard".
- Similar to the Judgment of Corruption PV, after Ma appears, a tunnel is being fallen through towards the end, with five colored rings along the tunnels of the walls; each ring is the color of the Deadly Sin representing it, excluding greed and wrath, and appears in the song series' chronological order.
- During the ending instrumental in the song PV, illustrations for each of the other six characters featured in their representative song in the series appear in reverse chronologicial order; afterwards, all six line up with the six shots in Nemesis' gun cylinder that's pointed at the viewer before fading away.
- The illustration for Gallerian in particular is lined up with the revolver's gun barrel as well; the moment after the illustration fades away, the revolver's barrel flashes the screen to white, as if being fired.
- Humorously, mothy admitted he had uploaded the song on August 8th, the eighth day of the eighth month of the year, by pure coincidence, not noticing the date until shortly before he posted it; Nemesis, the song's central character, happens to have the codename "Eight".
