Have you ever thought that in the shadows of skyscrapers there are monsters that eat away at the years? Have you ever thought that deep in the old buildings where no one has ever set foot, there live forgotten old gods? Have you ever thought that those people who are regarded as crazy by the world are holding the last line of defense in the world?
Under the brightly lit city, something strange lurks; in the deserted corners, the old gods sleep. The guardian who belongs to the human world is standing in front of millions of people with his mortal body. In this world, no strange things are allowed to be trampled; in this heaven and earth, no foreign gods are allowed to run rampant!
