The supernatural is returning, killing according to its own rules. The modern technology humanity takes pride in cannot detect it, contain it, or stop it. By harnessing the supernatural and cursed objects, enduring their consumption and corruption, and actively dealing with paranormal incidents, humanity has barely managed to keep the situation under control. Yet things continue to worsen. With survival at stake, the "Ghost Exchange," a faction within the Salvationists, strikes a pact with a supernatural being possessing the consciousness of a living person. They help it complete its puzzle and aid it in becoming the Lord of the Supernatural. Are they helping a tiger hunt, or buying humanity time and creating a chance to survive and turn things around?
