I reincarnated into a novel… but, hey… What am I supposed to do if I reincarnate in 10 years before the novel begins? The location: prison. The problem is that even a jungle is better than this place! After ten years finally passed, I became the top dog in this prison. * “Hey Mint. Cut it out. Don’t go overboard.” “I have no idea what you’re talking about.” I became a good-for-nothing leader, but I’m fine with that. That’s a privilege a pro gets. “I’ll make you dead on paper, so do me one last favour.” “I have no idea what you’re on about.” A golden opportunity was bestowed upon me. “If you help me, I’ll release you from prison.” “What do you want me to do, Master?” “...” The chief of the prison asked me, the psycho of the prison, for a favor. “Make the new guy coming into the leader of this prison.” It may be called a prison, but in reality, it’s a lawless place. If I can make one man into the leader, I can finally be released. “But to do that, you need to enter a male prison.” “...Huh? How can I attach something that’s not there and get in?” But oh god? The new guy is the male lead of the original novel.
