The largest cyber-terror attack in city history occurred in 2080. (Lol, the image changed for some reason.)
The year is 2080.
With highly developed AI and cybernetics, human life has become completely dependent on the network.
Neo Arcadia is a futuristic city ruled by giant corporations.
Self-driving cars racing through the sky, holographic advertisements, and cybernetically enhanced people. At first glance, it was a perfectly managed, ideal city.
However, one night—a massive cyber-terror attack engulfing the entire city occurred.
Transportation systems, medical institutions, military networks, and urban AI. Every system was infiltrated simultaneously, and city functions ceased for several hours. The culprit vanished, leaving only traces of unauthorized access to the highest-authority AI at the heart of the city.
To solve the case, the government established the special investigation organization "NEXUS."
Ten elites, each with different areas of expertise, were gathered.
They began to hunt the culprit together.
But—as the investigation progressed, a certain fact surfaced.
"The culprit did not infiltrate from the outside."
The culprit is inside NEXUS.
Among the ten members, the very person who triggered the cyber-terror attack is hiding.
Who is an ally, and who is the enemy?
And why did the culprit infiltrate the organization looking for them?
When the truth is known, the relationships between the eleven people will begin to crumble—.

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

The year is 2080 AD.
A future society where AI, cybernetic technology, quantum communication, and neural networks have developed to their limits.
"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-powered terrorism, personality data falsification, cybernetic hacking, memory crimes, and illegal body modification—are rapidly increasing.
Established as a special organization directly under the government—
"NEXUS"
The Special Crime Countermeasures Agency.
