Welcome to a school where the lessons go far beyond books and far more dangerous than you ever imagined. A school where every day is a fight to stay ahead-or at least, stay alive. Every door hides a secrets, every classroom holds a trap, every lesson comes with a cost, and every face could be friend... or enemy. Here, grades aren't the only thing that matters. Your instincts, your courage, and your ability to read people are the real tests. How long can you last when every step could be your last?
