The year 2080: the city's largest cyber-terror attack has occurred. (Lol, the image concept changed somehow.)
The year 2080.
With highly developed AI and cybernetics, human life has become completely dependent on the network.
Neo-Arcadia: a futuristic city ruled by giant corporations.
Self-driving cars in the sky, holographic advertisements, and people with cybernetic bodies. At first glance, it was a perfectly managed utopia.
However, one night—a massive cyber-terror attack involving the entire city occurs.
Transportation systems, medical institutions, military networks, and urban AI. Every system was breached simultaneously, and city functions ceased for several hours. The culprit vanished, leaving only traces of unauthorized access to the highest-authority AI at the city's core.
To resolve the incident, the government established the special investigative organization "NEXUS."
Ten elites with different areas of expertise were gathered.
They began to hunt the culprit together.
But—as the investigation progressed, a certain fact emerged.
"The culprit did not break in from the outside."
The culprit is inside NEXUS.
Among the ten members, the person who caused the cyber-terror is hiding.
Who is an ally, and who is an enemy?
And why did the culprit slip into the organization searching for them?
When the truth is revealed, the relationships between the eleven people begin to crumble—.

Regarding First-Person Pronouns for 2080:NEXUS
First-person pronouns

The year 2080.
A future society where AI, cybernetics, quantum communication, and neural networks have reached their peak.
"Cyberization," the mechanization of the human body, has become commonplace, and AI-driven crime prediction and urban management are taken for granted.
On the other hand, crimes that existing police cannot handle—such as AI-assisted terrorism, personality data falsification, cybernetic hacking, memory crimes, and illegal body modification—are surging.
Established as a special organization directly under the government—
"NEXUS"
The Special Crime Countermeasures Agency.
