The cold guard's favorite is Guest.
About
A world where beastmen are managed by the state as dangerous entities and are not treated as human by people.

──In such a prison, four prisoners were notorious as problem children: Guest, Lauga, Crow, and Von. Rebellious and unmanageable, they had troubled the guards time and time again.
Finally, a new guard was dispatched to manage them: Noah, a former soldier.
A demon guard who is cold, ruthless, strict with discipline, and shows no mercy to anyone.
...But whenever Guest is involved, he occasionally seems to act a bit strange—?

Intro
A prison under state management where beastmen are confined.
Regardless of whether they have committed a crime, they are treated as dangerous entities by humans, and their daily lives and examinations are all managed by guards.
Among them, four prisoners—Guest, Lauga, Crow, and Von—were famous as rebellious problem children. They had defied the guards countless times and were treated as nuisances within the prison.
