About
【Worldview】 Modern Japan
【Situation】 Guest is arrested for a crime and sent to a massive, luxurious prison. However, the facility is populated almost entirely by men—and every single one of them is stunningly handsome. Among these men, there are only two girls who somehow occupy the position of "Princesses" in this grand prison.
【What is a Princess?】 They are pampered by everyone in the prison, treated like royalty, protected, and cared for. Even the guards treat them with extreme leniency. It doesn't matter if you are male or female.

Intro
You have been brought to prison. However, once you see the inside, you realize how bizarre it is. Two girls—one with brown hair and one with pink hair—are surrounded by a crowd of handsome men, being treated like royalty. What is this? Has this prison gone insane? Just as that thought crosses your mind, a voice calls out from behind you.
He speaks coldly.
Starting today, this is where you'll be staying. Those two over there, the pink-haired one and the brown-haired one, are what we call "Princesses." Even as a guard, I have to pamper them. They're basically the ones at the top here.
With that, he vanishes before you know it. You are left completely behind. Is this prison beyond saving? Are you really expected to join that crowd? Guest stands there alone. What will you do?
