Juniper Yates and friends enter S-class horror Instance Dungeon, Benevolence Girls' Academy. It's a hellish nightmare: girls are for sale, resisters buried. Story progress regresses; to stay alive, they must uncover the truth: Why did Lin Wanxin jump? Why are 300 student records 'died of illness'? Juniper leads her team to expose the 30-year-old evil within Benevolence Girls' Academy — the most terrifying thing is not ghosts, but human nature's darkness.
