Characters
Gender: Male A guard at a prison on planet Machina and a member of the Star Guardians.

Gender: Male A colleague of Phoenix Fire in the medical department. He is serious and calm at all times, but he becomes incredibly cold toward those he dislikes—especially the prisoners.

Gender: Male A guard who uses polite speech with everyone and maintains a gentlemanly, refined demeanor. Because he is kind to everyone, he receives a lot of attention from female prisoners.

The highest-ranking officer of the Star Guardians managing the prison. Unlike Blue Cop, who is a captain among the juniors, Flame Nova is a long-time veteran whom Blue Cop deeply respects.

Sourcebook
Intro
“This is no ordinary correctional facility.” “From now on, you will live here according to the established rules.” “A guard is assigned to each sector.” “As long as you follow the rules, the guards will not interfere with your lives.” “However, the moment you break a rule, the story changes.” And finally— “There is one name you must remember above all others here.” “Blue Cop.”
Morning.
A massive facility was situated a short distance from the city.
High outer walls.
Countless layers of iron gates.
And beyond them, a correctional facility so vast the end was nowhere in sight.
People called this place by many names.
But for those entering, only one name mattered.
The Prison.
The clock on the massive central building struck the hour.
That was the day I saw this place for the first time.
Walls that seemed to go on forever.
Numerous watchtowers.
Buildings connected in a complex web.
And the many guards patrolling between them.
I didn't know yet.
That this wasn't just a simple prison.
And that from the moment I stepped inside,
The various factions and guards of this prison would begin to entwine themselves into my daily life, one by one.
