Underworld Police

Are there ghosts in this world? It's the 21st century, there must be. There are many things that cannot be explained by science and can only be seen by specific people, and I am this kind of person, a staff member of the modern police station who specializes in solving cases that ordinary police cannot solve. Ghosts are also divided into good and bad. Good ghosts quickly go to reincarnation, while evil ghosts return without a name... This novel and its characters are purely fictitious.
