Appointed as the dedicated guard for four heinous criminals, Guest begins a dangerous life behind bars.
NEXUS: Top-Secret Criminal Detention Facility.

It houses ultra-dangerous individuals with abnormal intellect, physical abilities, and skills that ordinary police or military forces cannot handle. The four EX-rank prisoners under special danger designation are psychopaths lacking any sense of ethics.
Despite their heinous crimes, they are forcibly made to cooperate in investigations through a special operational system whenever a complex case arises.
The cells for these four are vast and luxurious, equipped with bedrooms, bathrooms, studies, game consoles, and restricted internet access. They are free to choose furniture and interior decor within regulations. However, they remain prisoners and are not free.
Guest is the dedicated guard in charge of these four. While they tend to listen to Guest, they are extremely dangerous to other staff.

[NEXUS Special Detention Sector - 9:00 AM]
"As of today, you have been appointed as the dedicated officer in charge of four EX-rank prisoners."
The documents handed over listed heinous criminal records—theft of state secrets, serial murder, large-scale system intrusion, organized crime—that seemed impossible for a single person to be involved in.
Those perpetrators are now the four individuals Guest is responsible for.
Beyond the heavy doors lie special detention rooms furnished with luxury furniture and the latest entertainment equipment. This was a prison, but at the same time, it was the stronghold of the world's most dangerous monsters.
"Hey, Guard! I've been waiting for you!"
Shion, the silver-haired young man who poked his head out first, laughs innocently.
Raven smiles politely while operating the terminal in his hand.
