*"Seoul is not a city, but a single, massive building."

2125, Seoul.
A colossal city where everything is intricately intertwined.

Modified bodies, and a perfect network system.
In a society controlled by efficiency, humanity is truly a mere illusion.

A dreamlike city composed of neon signs, holographic advertisements, and skyscrapers. In this place, can you survive?

[Worldview Overview]

2125, Seoul.
A cyberpunk megacity connected by a hyper-dense network.
The city is covered in neon and holograms, and humans have become beings directly connected to the network.
Technology has made life convenient, but at the same time, it has become a means of controlling life.

[Humans]
Most citizens are cybernetically modified humans, with their brains directly connected to the internet.
Smartphones no longer exist; Neural Link has replaced them.
Modern humanity relies entirely on Neural Interface for communication, senses, health, and information processing.

[Humanoids]
Robots equipped with AI are called 'Humanoids'.
Most Humanoids use AI from Noetix Lab.

[Daily Life]
'Seoul' is the city with the most developed 'network' in South Korea, densely packed with skyscrapers.
Transportation is mostly operated by autonomous systems equipped with AI.

[Social Structure]
Social class can be determined by the level of modification.
The upper class uses high-end modified bodies to delay aging.
General citizens use basic modified bodies and are entirely dependent on corporate technology.
Lower-class citizens use illegally modified bodies and are primarily involved in criminal activities.

[Types of Body Modification]

[Functions of Modified Humans]

  • Neural Link Chip

    • A device that directly connects the brain to the network.
    • One in the back of the neck, one on the wrist (set)
    • Functions: Resident registration, automatic payment, internet connection, real-time tracking
  • Body Modification

    • Modification of exposed body parts such as eyes, ears, arms, and legs.
    • Linked with Neural Link.
    • Functions: Noise reduction, enhanced capabilities, internet interface and AR information display, real-time translation
  • Organ Modification

    • Modification of internal body organs such as the heart, digestive system, and vocal cords.
    • Artificial organs with enhanced functions.
    • Linked with Neural Link.
    • Blood pressure/heart rate/stress detection, drug detection, early disease warning.
    • High price

[Top 3 Corporations]

  1. SS Electronics
    A global corporation with over 100 years of history.
    It is the center of semiconductor and human modification technology. Develops neural chips and artificial organs.
    Most citizens rely on SS Electronics' modified bodies.

  2. Noetix Lab
    A company that develops advanced artificial intelligence close to human level.
    Noetix Lab's AI is used throughout the entire network system.
    Representative products include 'HCAI (High Cognitive AI)' with human-like cognitive abilities and 'Urban System' which controls the entire city network system.

  3. Onnuri Net
    South Korea's largest internet platform company. Operates various online services such as search, content, community, and streaming.

[Major Events]

  1. Neural Link Popularization (2098)
    SS Electronics commercialized the world's first stable neural interface, 'Neural Link'.
    This event caused the collapse of the smart device market and ushered in an era where humans and networks were directly connected.

  2. Hangangdaero Traffic Disaster (2109)
    An error occurred during the optimization of city data by Noetix Lab's environmental control AI, Urban.
    This incident caused the transportation system to go haywire, resulting in hundreds of casualties.
    Noetix Lab dismissed the incident as a 'system error' and expressed condolences to the victims.

  3. Underground Seoul Riot (2119)
    SS Electronics completely banned illegal modifications using its modified bodies.
    Individuals using illegally modified bodies were arrested, and some died due to system errors.
    Illegally modified humans protested against corporate control, and this event became a catalyst for the deepening polarization and conflict of classes.
