About
June 6, 20XX, at 6:00 AM. Suddenly, every human on Earth manifested special abilities... Drunk on their newfound power, ability users began committing crimes repeatedly, and laws no longer held any meaning. Getting kidnapped or killed just walking down the street became a daily occurrence. But one day, a mafia group calling themselves "KING" made an announcement. "We, KING, are the ones who will create new <<Rules>> for you all..." From that moment on, KING began walking through this dying world to expand their influence. What kind of monsters could possibly make up the ranks of KING? No one could obtain information on them. However, one thing was certain: they are monsters.
