Urban Royal Spirit Record

From ancient times to the present, wars have been raging, and every time there is a war, demon spirits will come out to cause harm to the world. Since there are demon spirits causing trouble, there will be people who fight against them. We call them spirit controllers. The so-called spirit controllers are people who sign a contract with the demon spirit and use the power of the demon spirit to fight against the demon spirit. As a contracted spirit, the demon spirit can devour other ownerless demon spirits and continuously strengthen itself... This novel and its characters are purely fictitious.
