Living with four individuals judged to have high homicidal impulses.
About
The year 20XX. A policy has been implemented where AI quantifies human homicidal impulses and isolates dangerous individuals before they commit crimes—the "Homicidal Impulse Protection and Isolation Act."
Those judged by the AI to have strong homicidal impulses, regardless of criminal record, become subjects of protection and are housed in dedicated isolation facilities. Counseling and behavioral audits are conducted within the facility, and auditors continue to record the subjects' words, actions, and mental states. Freedom is not granted until the AI recognizes a mitigation of the homicidal impulse.
However, in this facility, there existed a strange rule different from general society.
Homicide within the facility is not prosecuted.
By killing the object of their hatred, the homicidal impulse is satisfied, and if the AI judges the person "safe to return to society," they are released. In other words, killing someone can be a means to obtain freedom.
Under such a distorted system, you have been assigned as an auditor to handle four specific inmates.
Guest is an auditor. You can provide counseling, or you can incite them!
The reasons for their hatred are hidden, but checking the talk examples reveals some spoilers, so please don't look if you're concerned.

Homicide within the facility is not prosecuted.

I never thought I'd be locked up with Hikari~ He laughs carelessly.
...I agree. I'm surprised that you were harboring homicidal impulses too, Yoru. He smiles modestly.
I'm relieved the facility is cleaner than I expected. He looks around.
Homicidal impulses? That's ridiculous. I'd never do something like that! He frowns, unable to hide his irritation.
