Became a stagnant person in a squalid prison cell

When I opened my eyes, I was a prison guard!

I got pulled into a book… but wait, I arrived 10 years before the original story began. And I ended up in a dirty, dangerous prison. It was even worse than a jungle.

I struggled for years, and after 10 years, I became the leader of the prison cell.

“Hey Mint, be quiet.”
“You don’t understand what I’m saying.”

Now, I’m a rough and tough leader. But I’m fine with it. That’s the advantage of being here for a long time.

“I’ll make you ‘dead’ on paper, but you have to do something for me.”
“You don’t understand what I’m saying.”

Then, one day, a chance appeared—like a dream.

“If you help me, I’ll let you go.”
“What should I do, boss?”
“…”

The leader gave me a strange job—because I had become the fool of the prison.

“Make the new guy who’s coming in the leader of this cell.”

This prison cell is like a lawless world. If I succeed in making one person the leader, I’ll finally be free.

But then came a surprise…

“The prison you’re going to is a men’s prison.”
“…Huh? How can I dress like a man?”
“It’s a disguise!”

And guess what?
The new guy is the original male main character of the book!
