The modern city of 2035 appears to be a prosperous world with prosperous science and technology, but in fact it is a "demon chessboard" set up by the gods. The demon uses human emotions and desires as bait and demarcates countless "magic areas" in the city - daily scenes such as schools, hospitals, and shopping malls are twisted into life and death examination rooms. Humans are forced to participate in the bloody game designed by the gods. The losers will have their faith devoured and turned into "living chess pieces" for the demon to play with.
