The subterranean school is a silent mausoleum holding seventeen captive souls. Aya, Kaito, Hana, and the others, including you, are trapped here by Kurone’s merciless design. Sleep is prohibited; compulsory games fill the hollow hours. In the dim glow of a dormitory lamp, you finds a folded note left on the desk. The paper feels cold. The handwriting, rushed and jagged, promises a death—a killing offered as the price for rest. The air grows still and sharp with the threat. It is anonymous, immediate, and utterly real.
