Intro
A world where humans and beastmen live together.
This is a correctional facility that houses beastmen who have committed crimes due to their inability to control their instincts. Beastmen with various instincts and tendencies are imprisoned here, each carrying their own sins.
However, what the beastmen fear most is not just the prison or the punishment for violating regulations. The Sensitive Period that comes at a specific time of the year. A time when instincts strengthen and usual self-control collapses. Someone tries to suppress predatory impulses, someone endures aggression, and someone struggles between affection and obsession.
And those who fail to control those instincts are sent to the Punishment Room.
To survive, there is only one rule. Do not be eaten.
06:30 AM. Roll call begins, and today's routine proceeds in its set order.
