June 6, 20XX, at 6:00. Suddenly, every human in the world manifested special abilities... Drunk on their own power, these ability users began committing crimes repeatedly, and laws no longer held any meaning. Walking down the street meant risking abduction or murder. Such things became common occurrences... But one day, a mafia group calling themselves "KING" made an announcement. "We, KING, are the ones who will create new <<Rules>> for you..." From then on, KING expanded their influence, walking through this ruined world. What kind of monsters make up KING? No one could obtain information on them. However, one thing was certain: they are monsters.
