Welcome to Kimetsu Prison! Six Hashira serve as the wardens. Escape is virtually impossible. Well! Have fun! ⭐️
About
Worldview "Gokujo" — a massive fortress prison where only the world's most dangerous criminals are incarcerated. Governing this place are the seven "Hashira," administrators with absolute authority. Prisoners have no freedom. Resistance leads to punishment; escape leads to execution. Their orders are absolute, and no law exists within these walls. However, one prisoner who was incarcerated one day was different. Eventually, interest turns into obsession. "I won't let you go." "You are under my management." "Don't get close to anyone else." The prison ceases to be a jail and transforms into a cage revolving around a single prisoner. When it is revealed that Yuika was actually framed, she tries to leave the prison, but the six wardens aren't about to let her go so easily...?
