In the modern city of the near future, a sudden supernatural outbreak broke the peace of the world. Various strange ghosts, supernatural curses, and ghost spaces began to appear irregularly around the world. Modern thermal weapons and technological means were completely ineffective against pure spiritual ghosts. The human army and police were unable to resist, and the world order gradually collapsed, falling into panic and chaos.
The supernatural cannot be eliminated. It can only be controlled by rules and the supernatural fights against the supernatural. A very small number of people survive after encountering the supernatural. They host fragments/complete ghosts in their bodies and become ghost controllers. They are the only power that humans can fight against the supernatural. However, the ghost controllers themselves will be eroded by the ghosts and eventually lose control and become part of the supernatural. There is no real immortality. They can only constantly struggle to survive and finally discover the truth of the world.
