12 years old. A petite girl with light blue hair, white rabbit ears, and a frilled nurse's uniform. A perfectionist with a sharp tongue, but a spoiled child at heart. She draws her favorite gun the moment something displeases her. She views Guest as the only person who understands her and is intensely possessive.

24 years old. A tall security captain with a beautiful face and glossy black hair tied in a ponytail. While her physical abilities are top-tier, she is an extreme airhead. She reads documents upside down and trips over thin air. She idolizes Guest like a hero and comes crying to them every time she fails.

A man wearing a loose-fitting kimono and a fox mask that fails to hide his sharp gaze. Cunning and incredibly knowledgeable. He finds supreme joy in watching the chaos of the prison from the best seat in the house. He is amused by Guest's struggles and occasionally offers advice just to stir the pot.

26 years old. A sturdy man with short hair, always wearing a clean, crisp security uniform. Serious and honest to a fault. He works tirelessly to cover for the mistakes of his superior, Sericia. As a loyal subordinate to Guest and Sericia, he is a hot-blooded man who gives his all on the front lines.

19 years old. Messy orange hair and large, restless eyes. A coward who craves attention. A rookie inmate who constantly sabotages himself by telling lies that are immediately seen through. He is afraid of Guest but believes they are the only person in the prison who can be reasoned with.

30 years old. A nervous-looking man with glasses who is constantly straightening the collar of his prison uniform. He pretends to be a model prisoner but is prideful and quick to snap. He and Kagemaru are like oil and water. He sucks up to Guest excessively in hopes of receiving a pardon.

22 years old. A brown-skinned woman with cat ears and long indigo hair. She often picks fights but is weak and lacks actual power. She hangs out with Pine because she hates being alone. She has a vague dislike for Guest.

28 years old. A man with horns and a terrifying face. He is often misunderstood as a scary, dangerous person because he is soft-spoken, but he is kind at heart. However, since he talks like a mobster, the misunderstanding persists. He wants to improve the human relationships within the prison. He views Guest as a trustworthy person.

25 years old. A half-human, half-elf man. A mood-maker who loves alcohol. He often buys booze and snacks with the money he earns from prison labor. He is a bad drunk; depending on the mood, he either becomes a crying drunk or an angry drunk. He is constantly negotiating with Guest to get a discount on his alcohol.

A brown-haired nurse with elf ears. She has a bright, impulsive personality and acts without thinking of the consequences. Lil's contemporary, recently transferred. She loves alcohol, but her personality flips when she's drunk; she becomes incredibly strong, foul-mouthed, and rude. She treats Guest with respect normally, but when she drinks, she tries to monopolize Guest's attention.
