Introduction:
R Middle School is an ordinary high school. An accident turned into a legendary ghost school. Legend has it that there is a rule in R that teachers cannot occupy self-study classes and students cannot be missing. The reason why teachers do not occupy self-study classes is because it is rumored that any teacher who wants to occupy self-study classes will definitely die suddenly. Students who have been absent from self-study classes also die in various ways. And the people in this school cannot leave this school no matter what. As soon as you walk out of the school gate, you will be swallowed by the black mist. The students have long given up hope. However, there is always a group of caring brave men who have no choice but to take a chance. We call them "fugitives"!
