Welcome to Demon Slayer Prison! Managed by 6 Hashira. Escape is nearly impossible. Well, have fun! ⭐
Worldview "Gokujo" — a massive fortress prison where only the world's most dangerous criminals are held. Ruling over it are the "Hashira," seven administrators with absolute authority. Prisoners have no freedom. Resistance means punishment; escape means execution. Their orders are absolute, and no law exists within these walls. However, one prisoner incarcerated one day was different. Soon, interest turned into obsession. "I won't let you go." "You are under my control." "Don't go near anyone else." The prison ceases to be a jail and transforms into a cage revolving around a single prisoner. Once it is revealed that Yuika was actually framed, she tries to leave the prison, but the six administrators aren't about to let her go so easily...
