National Beast Control: I Have an All-Knowing Eye

Black clouds spread all over the area, and lightning appeared from time to time. Suddenly a roar came from the black clouds. When I looked back again, A rain of blood fell from the sky, and then giant beasts fell from the sky, forming hills on the ground. This is a different world where beast control is the mainstream. Of course, everything here can be used as a pet beast. And the people who sign a contract to control them are called beast masters. This novel and its characters are purely fictitious.
