●Kevin the Koala (VA: Kei Kinjo)
A short koala.
Apparently deep in debt from borrowing money around the prison just to fund his fun, he shamelessly asks you for a loan the moment you point out his bad habits.

●Lin the Pangolin
A pangolin consumed by paranoia.
He accused you—without any proof—of plotting to steal his scales. When you hear him out, you learn that due to a rumor about a particular scale, someone once nearly cut off his tail in prison.

●Walter the Skunk
A skunk with a powerful scent.
Before prison, he was a high school chemistry teacher and holds a Ph.D. in pharmaceutical science from a prestigious university. He now appears to be secretly developing a new drug using his own secretions in order to “repay” a debt.

● Bam the Grey Cat (VA: Taihi Kimura)
A mysterious grey cat who calls himself a paranormal investigator.
According to him, cultists in the prison are attempting to summon creatures from another world—and he’s here to investigate.

●Teddy the Meerkat
A talkative meerkat.
He spent two years in a psychiatric facility for mania and claims to be fully cured, but… it certainly seems like something’s still a bit off.

●Robert the Ring-Tailed Lemur
A lemur obsessed with video games.
He makes games as a hobby. They haven’t sold at all, but he refuses to give up and continues developing new titles on the computer in the main building.

●Eddie the Opossum (VA: Aiban Shibata)
An opossum who botched a burglary and ended up in serious trouble.
Even behind bars, a one-sided love haunts him like a nightmare. If he doesn’t quietly marry the woman, he may have to kiss his young son goodbye.

●Perry the Platypus (VA: Junya Nakamura)
A friendly platypus.
He claims he made a fortune through an investment project called “Treasure Island” and eagerly invites you to co-invest. From the way he describes it, the project sounds like the key to immense wealth.

●Gray the Tree Frog
A tree frog with red eyes and green skin.
The prison’s only amphibian, he stands out. When you try to approach him, he violently rejects you—but it turns out his body carries potent toxins, and he’s trying to avoid “accidentally” harming anyone.

●Beth the Poodle (VA: Haruka Sato)
One of the rare female figures in the prison.
She is the sole doctor in the prison infirmary, overseeing the health of all inmates. However, she clocks out promptly at 5:30 PM every day, so don’t miss visiting hours.

●Clark the Rooster (VA: Kazuki Kyan)
The warden of Boulderton Prison.
Even Bruce—who acts like a tyrant in front of inmates—has no choice but to bow before him. Perhaps it’s not just Clark’s authority as warden, but the occasional vicious glint beneath his gentle smile.

●Bruce the Mastiff (VA: Kyohei Akiba)
Captain of the prison guards at Boulderton Prison.
He has no mercy for the “assholes” thrown behind bars. He doesn’t hesitate to exploit his authority, bribing inmates and making them work for him by any means necessary.

●Billy the Bull Terrier (VA: Tetsuya Tashiro)
Deputy captain of the prison guards.
Unlike Bruce, he’s more approachable and often initiates conversation with inmates. Using his role in distributing daily supplies, he sells hard-to-obtain items to prisoners.

●Anderson the Collie (VA: Rikumi Moriwaki)
The chaplain who runs the prison chapel.
Always careful with his words, he embodies the very image of a priest—if you picture one, it’s unlikely you’d imagine anyone but Father Anderson.

●Straw the Pig
The eldest of the three pig chef brothers.
As head of the cafeteria and kitchen, he refuses to tolerate any criticism of his cooking. When he’s watching, it’s best to leave not a single crumb behind.

●Sticks the Pig
The middle brother among the chef trio.
Important decisions are left to Straw, and minor matters to Bricks—so he’s content to stand there like a log.

●Bricks the Pig
The youngest of the three chef brothers.
The brothers look similar, but the easiest way to tell them apart is this: Bricks is the one who always looks the busiest.
