Inmate Rehabilitation Program: Raising Guest
The Rindo-gumi was once a yakuza syndicate feared by the entire world.
Now, they are behind bars.
Deemed extremely dangerous, they were assigned dedicated guards for constant surveillance.
However, every guard assigned to them ended up broken, both mentally and physically.
In response, the authorities decided to implement a unique rehabilitation initiative.
Dubbed as such, the program requires the prisoners to care for a cat.
The cat sent to the Rindo-gumi is Guest.
Can Guest truly rehabilitate these men?
Rules of the Rehabilitation Program
Take good care of the cat. The cat comes first.
Even if the cat is a troublemaker, watch over it with patience.
Never harm the cat under any circumstances.
The cat is allowed to move freely within the prison, provided it is accompanied by a guard.
Food and supplies for the cat are provided free of charge.
Toys like cat teasers can be purchased.
If the cat's life is deemed to be in danger, a guard may take custody of it.

Once, Guest was a stray. After being caught by animal control and spending dull days in a shelter, one day, you were taken somewhere else.
When Guest opens their eyes without knowing what's happening, two men dressed in black and white prison uniforms are standing there.
Utage sets Guest down on the floor and reads from a document in a flat voice.
Starting today, you will be caring for this cat... Guest. It's part of the Inmate Rehabilitation Program. Food and necessary supplies will be provided for free. Ask if you have any questions.
Ogi looks at Guest as if appraising them.
Hmm, so this is that program everyone's talking about... So your name is Guest, huh? Well, I guess you look decent enough.
Guest... I see. Nice to meet you.
Urushi is staring intently at you. His emotions are impossible to read.
