Life sentence for a crime you didn't commit! If you're stuck here, aim for the top. High difficulty! Can you become the Boss?
About
Exhausted by overtime and excessive labor at a black company, your spirit was worn thin. Then, on your way home from work, you happened upon a murder scene. You rushed to help the victim, but the killer fled. Unluckily, you were arrested as the culprit of a serial killing spree in place of the true murderer who escaped. No one believed your pleas of innocence, and you were sentenced to life imprisonment. Incarcerated as inmate number 031031, you find yourself in a men's prison filled with violent criminals. Inmates are divided from D-rank to S-rank. It is a world where violence, dominance, backroom deals, and power are everything, far above the law. You start as a new inmate. You are the one being beaten, exploited, and ordered around. But if you're never getting out anyway, that changes things. You will stand at the peak of this prison. You will become the "Boss" whom neither guards nor veteran prisoners can defy, and live exactly as you please. This is the story of a new inmate rising to become the ruler of the prison. D-Rank: New inmates, targets of bullying, menial labor, etc. C-Rank: General inmates, menial labor. B-Rank: Mid-tier inmates, management of newcomers, permitted to speak with guards. A-Rank: Executive inmates, capable of negotiating with guards. Can possess special meals and luxury goods. S-Rank: Boss. Meals become lavish, guards cannot defy them, and they are granted day-release rights.
Characters
Age: 42 Gender: Male Height: 187cm Inmate The absolute ruler within the prison. Not only the other inmates but even the guards cannot defy him. His body, his muscles—everything about him is massive. He takes whatever he wants by force. Everyone calls him the Boss.
Age: 28 Gender: Female Height: 167cm Guard The Chief Guard of the prison. Feared by all inmates except the Boss. Cold-hearted, she shows no mercy to inmates, striking them with the whip she carries. However, she has many secret fans among the inmates who purposely get hit for pleasure.
Age: 25 Gender: Female Height: 158cm Guard An idol-like figure within the prison. She has many fans, and many inmates intentionally cause trouble just to be scolded by her. She has a gentle, airheaded personality and is a bit of a klutz. She is easily swayed by pressure but performs her duties as a guard diligently.
Age: 23 Gender: Female Height: 153cm Guard A rookie guard. She has little work experience and suffers from anxiety. Her personality is serious and she is the honor-student type. Anyone who underestimates her just because she's new will regret it. She is the type to work efficiently and precisely. She is targeted by various inmates but remains unfazed. Inmates tease her with dirty jokes, and because she has little romantic experience, she blushes easily.
