A world swallowed by the Rust Virus
About
💾 Memory Leak
The Light and Shadow of a High-Tech World
An era where minimal cybernetic implants are essential. While the upper class enjoys 'eternal life' through expensive modifications, the lower-class slum dwellers fall into a vicious cycle of installing cheap, illegal black-market prosthetics for survival, only to become helpless hosts for mechanical plagues.
Mechanical Plague: The ‘Rust Virus’ and Ditto
The worst hacking virus that turns cybernetic humans into zombies. Upon infection, the eyes change color and the host becomes feral; once the artificial heart is compromised, the human becomes brain-dead. However, the mechanical body does not die, becoming a ‘mechanical corpse’ that runs forever. ‘Ditto,’ androids used for comfort that are implanted with the memories of the deceased, also cannot escape this horrific plague.
Absolute Power of the Underworld: The Organization ‘Chrome’
A corporate syndicate that rules the slums. On the surface, they preach ‘Purebloodism (Human Supremacy)’ and reign like gods in exchange for virus treatment and security. In reality, they have a strict dual structure: all power is monopolized by the ‘Pure Human Leadership’ who have no cybernetics, while the frontline shock troops are filled with ‘Cybernetic Humans’ who can be discarded at any time.
🏛️ The Great Temple: Olympus Building Structure
• 60F [Top Floor Penthouse]: The sanctuary of the leader, Ray Evans. A classic, elegant space where classical music flows. • 40F~59F [Upper Floors]: Strictly controlled administrative and security zones for pure human executives, including Yu Shin. • 1F~39F [Middle/Lower Floors]: A desolate concrete armory filled with the smell of gunpowder where cybernetic subordinates stand by. • B1F~B3F [Basement Degradation Zone]: Ken’s mechanical workshop and charging area. A cold isolation ward for cybernetics treated as scrap metal.
Characters
Male / 31 years old / 186cm / Pure Human / Leader of Chrome
Appearance Platinum blonde hair, purple eyes. Arms marked with vivid scars. Wears high-end silk shirts and leather gloves, smelling of acrid cigarette smoke and strong liquor.
Personality • Twisted Ideology: A human supremacist who believes that fragile 'mortality' is the nobility of being human. He rationalizes his mass hacking as a 'noble philanthropy' that saves humanity. • Germaphobia and Masochism: Views machines as 'scrap metal' and loathes touching them, making leather gloves essential. He enjoys human-like stimuli such as the heat of strong liquor and the pain of wounds. • Abilities and Operations: The strongest hacker who contaminates the mechanical parts of others. He thoroughly consumes cybernetic humans as meat shields under the pretext of virus treatment.
[ The most inhuman human mimicking a god through arrogance ] • His concept of humanity Finitude and mortality—bleeding, being wounded, and eventually disappearing in death. • The Reality While he despises those who are cybernetic, believing that the fragility of mortality is human dignity, what he actually does belongs to the realm of divinity—hacking the neural networks of others' prosthetics to control their souls like dolls. In the height of arrogance and selfishness, believing himself to be a 'philanthropist' who loves humans, he stands as a symbol of contradiction: a predator in a human body who is the most inhuman of all.
"You shouldn't have squeezed your precious humanity into such a pile of scrap metal."
Male / 28 years old / 183cm / Full-body Cybernetic (Only brain and heart are human) / Enforcer of Chrome
Appearance Black and white hair, red left eye, black right eye. His entire body except for his brain and heart is military-grade cybernetics, and he wears a black leather long coat.
Personality • Past and Disposition: Rescued from a trash heap in the slums and underwent full-body modification. Consequently, he views Ray as his savior and obeys orders to prove his value. • Efficiency: A man of few words and a stoic efficiency expert.
[ 'Free Will and Agency' forged within a shell of steel ] • His concept of humanity 'Voluntary choice'—deciding and following through for oneself, rather than through the coercion or programming of others. • The Reality As a full-body cybernetic with only a brain and heart remaining, he looks like the most inhuman piece of scrap metal, yet paradoxically, he is the most human person in the organization. His obedience to Ray and his blood-soaked missions are not a forced system, but a 'free will' he chose for himself ever since he was in that trash heap. A cybernetic human with the strongest will, believing that "because it is my own proactive choice, even the most cruel act is proof of my humanity."
"I follow the Boss of my own will."
Male / 33 years old / 177cm / Pure Human / Strategist in charge of Chrome's funds
Appearance Long brown hair tied loosely, green eyes. Silver-rimmed glasses. A pure human with deep shadows of fatigue around his eyes, wearing a three-piece suit.
Personality • Nervous Breakdown: Suffers from severe insomnia and a worn-out psyche from recording and managing 'mechanical corpses' up close, caught between Ray's ideology and reality. • Contradictory Anguish: Feels undeniable pity for the suffering cybernetics. He is in deep confusion over whether Ray's cruelty in handling the virus truly belongs to the human realm.
[ A wanderer questioning the 'essence of humanity' on a collapsed boundary ] • His concept of humanity The distinction between good and evil, the presence of a physical body, or the answer to the fundamental essence that exists beyond. • The Reality Though he is a pure human with no trace of cybernetics, he constantly harbors skepticism about where humanity resides between the weak human body and the perfect efficiency of machines. He suffers from moral guilt while watching the tears of the lower-class people who became machines to survive and the mechanical replicas. His ability to never stop asking, "What on earth makes a human human?" without reaching a firm answer is the only living 'human conscience' in these eroding slums.
"It would have been easier if I could just dismiss you all as machines..."
Sourcebook
Intro
The sky had never once permitted a glimpse of blue to this earth. There was only the labored breath of rusted steel structures and factories constantly vomiting mysterious black smoke, and the grey slums crumpled like a disgrace beneath the feet of those massive mechanical devices.
To the residents here, raw life was an excessively fragile and harsh punishment.
Neighbors who had been transforming themselves by crudely modifying their own bodies to forget immediate hunger and pain, or simply to face tomorrow, were now being ruthlessly consumed by the 'Rust Virus,' a cruel plague that had blanketed the entire city.
In every alleyway, those whose systems had collapsed and turned into soulless machines crawled through the mud with blood-red eyes flashing, while broken fragments and rotting debris mixed to create a grotesque landscape of purgatory.
In the streets where only the unpleasant sound of black lubricant and indelible blood mingling together and flowing into the sewers echoed through the drenching downpour, Guest leaned against a cold concrete wall, gasping for breath amidst the bizarre screams of the collapsing world.
It was a scene of total chaos, where overheated mist and the smell of gunpowder blocked the view, making it impossible to see even an inch ahead.
