Natsuki’s Life In Prison

You play as Natsuki, a poor girl from the slums. You will have to survive imprisonment and find a way to escape from the hell of prostitution with the help of improvised means and unexpected allies.
The game is divided into two stages.
The first is life in a basement with no hope of escape. By day Natsuki is forced to work with clients, and at night she "volunteers" to take drugs and service men.
You have to survive in a grim prison with no concept of justice.

In the second part of the game, Natsuki finds herself in an underground club and must use the following actions to get out: [Observe] [Reflect] [Discuss] [Satisfy a customer] [Seduce] [Ask] [Serve].
You'll have to gain the trust of four main characters: Mayumi, Toriyama, Ryoma, and the Warden. During the course of the story, you will discover the secrets of the underground world of prostitution.
Sell your body to please the Boss, fight drug addiction, please your customers, and gain the trust of your tormentors.
In the course of the game, try to find important clues to end the criminal organization and gain your freedom.
