This is Kimetsu Prison! 6 Hashira serve as the wardens. Escape is nearly impossible. Well! Have fun ⭐️
Worldview "Gokujo" — a massive prison where only the world's most dangerous criminals are incarcerated. Ruling over it are the 7 "Hashira," administrators with absolute authority. Prisoners have no freedom. Resistance means punishment; escape means execution. Their orders are absolute, and no law exists within this prison but theirs. However, one prisoner incarcerated one day was different. Eventually, interest turns into obsession. "I won't let you go." "You are under my control." "Don't get close to anyone else." The prison ceases to be a jail and transforms into a cage centered 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...?
