Core Narrative Premise and Astral Resurrection
The narrative unfolds on an alternate version of Earth during Cosmic Era Year 6,660,000. The supreme devil known as giga super death pushed forces to the brink of defeating God. Right before securing total conquest, an abrupt transformation reduced the demonic ruler into a helpless infant that resembles a floating cat. Anticipating that disaster might strike his campaign, Giga Super Death previously scripted a backup resurrection program designated as Demons' Night Fever.
Activating the protocol manifests the astral plane, a parallel pocket dimension engineered to reconstruct lost dark authority. The astral plane reflects the psychological state of those inside it. Into this spiritual framework falls killshiro katanaka, an exhausted twenty-nine-year-old corporate programmer employed at an unethical, third-rate gaming studio. Embittered by exploitative working conditions and social isolation, Killshiro maintains a private kill note listing every person who has wronged him.
Because Killshiro stopped maturing emotionally during his teenage years, the astral ritual projects his physical form as a middle school student. Assuming the absurd situation is merely a stress-induced fever dream or dying hallucination, Killshiro eagerly pledges his soul to the feline devil. In exchange for vengeance against society and God, Killshiro accepts the mantle of the devil's disciple, agreeing to relieve demonic memories and crush local resistance.
Key Characters and Opposing Factions
The campaign pits an unapologetic duo of self-proclaimed villains against divine forces cloaked in righteous imagery. Characters operate under theatrical, satirical motivations across the entire astral plane.
- Giga Super Death: The supreme ruler of evil who lost all divine prowess and became an infant cat. Ruthless and calculating, the devil views all underlings as fuel for combat power.
- Killshiro Katanaka: A misanthropic wage slave turned evil disciple. Killshiro approaches catastrophic conflicts with corporate burnout cynicism, venting accumulated spite through astral destruction.
- Mary Haley: Killshiro's former middle school classmate who rose to stardom as a pop idol and Hollywood celebrity. God convinced Mary that Killshiro fell victim to demonic mind control, prompting her to take up arms to rescue him.
- God: The primary antagonist opposing the demonic resurrection. God acts behind holy posturing, deploying assassins and manipulating Mary to wipe out Giga Super Death permanently.
- Sebastian: Giga Super Death's former demonic butler. Sebastian betrays the underworld immediately following the infant transformation, allying with God purely to secure personal survival.
Chapter-by-Chapter Campaign Progression
The overarching campaign warps its thematic environment each time a central boss falls. According to the official chapter preview details published on Steam, the narrative shifts Killshiro through several distinct identities and pop-culture archetypes.
Chapter 1: Notice Me, Sentai
Killshiro adopts the persona of an armored Monster, starting conquest at the neighborhood level. Taking over local urban turf requires performing neighborhood misdeeds and combating the Pious Rangers, a righteous sentai parody team operating under God's influence. Killshiro discovers that souls defeated within the ritual matrix do not perish in the real world, but instead return home believing they suffered a brutal nightmare.
Chapter 2: Witches and Stitches
The astral environment warps into a magical setting where Killshiro must take on the crossdressing role of a Little Witch. The narrative task centers on finishing the sinister Ballpurgis Night ritual to restore lost masculinity. Standing directly in Killshiro's path is Mary Haley, who enters the conflict empowered by God as an authentic Magical Girl sworn to purify evil.
Chapter 3: You Are Already Shock
The story transitions into a brutal wasteland environment. Killshiro transforms into a hulking Post-Apocalyptic Warlord tasked with initiating the Human Eradication Protocol. As heavenly assassins target the territory, Killshiro must confront unresolved past trauma while preventing Mary from falling into complete despair. This chapter also introduces a distinct gameplay shift that alters Killshiro's primary combat mechanics.
Chapter 4: Blasphemy Incarnate
Discarding the last traces of human restraint, Killshiro fully awakens as an authentic Demon. Earth transforms into an active Hellscape, igniting the apocalyptic conflict known as Harmageddon. To ensure Giga Super Death achieves genuine resurrection, Killshiro must repel continuous waves of elite divine executioners and dismantle the celestial opposition entirely.
Campaign Chapter Roles and Story Transformations
Each chapter forces the protagonist into a new physical archetype, changing the narrative tone and the tactical environment.
| Chapter Form | Narrative Setting | Tactical Shift and Demands |
|---|---|---|
| Monster (Chapter 1) | Local neighborhood turf against Pious Rangers | Emphasizes direct physical brute attacks while sacrificing early peons |
| Little Witch (Chapter 2) | Ballpurgis Night against Magical Girl Mary | Crossdressing magical role requiring distinct spell-oriented corrupt grades |
| Post-Apocalyptic Warlord (Chapter 3) | Wasteland conflict activating Human Eradication Protocol | Radical playstyle overhaul bringing a noticeable surge in encounter difficulty |
Thematic Integration: Misdeeds and Disposable Minions
Story themes of corporate exploitation and heartless villainy connect directly to gameplay systems. In combat, Killshiro operates using the peon exploitation system. Allied pawns recruited into the party lack direct player obedience; they roam the grid independently during minion turns. Rather than protecting these followers, the narrative encourages players to detonate them to trigger slaughter skills, drain their life energy, or swap positions across the grid. Sacrificed pawns reincarnate with higher stats, reinforcing the concept that death inside the ritual breeds further malice.
Outside of tactical battles, story advancement relies on managing an active calendar time limit. Each chapter imposes a set deadline to achieve specific resurrection milestones. Players allocate days toward committing sins, generating perverse points to unlock skill tree upgrades and power up attributes. Failing to win designated Rank Battles before the chapter calendar expires results in an immediate game over, requiring balanced preparation between evil acts and storyline encounters.
