[Rules-based weird story, not invincible, not cool, no heroine, not brainless, not systematic, no harem, please be careful if you mind]
Rules are a curse! Seven days to escape? No, it's the seven hells!
Trapped in a nightmare campus on the first day of school! The doors and windows were welded shut by strange blood and rust, the scarlet sky shone over the city, and the cold broadcast announced the fatal rule: no leaving school within seven days!
We just want to live, but the rules themselves are a noose
We are not students at all! This purgatory of rules is a karmic cage intertwined by the heinous sins of the four of us in our previous lives—corruption, robbery, betrayal, and desperate suicide!
The radio demon who calls himself "Qu Jie" is the embodiment of our sins! The seven-day staircase is not a way to survive, but the ultimate judgment seat for the soul!
Blood rust spreads, the rules are twisted, and the countdown begins! Can we tear apart this eternal purgatory woven by our own sins before karma swallows us up?
