It's exhausting, isn't it?
About
June 6, 20XX, at 6:00 AM. Suddenly, every human on Earth manifested a special ability... Drunk on their newfound power, these ability-users turned to a life of crime, rendering laws obsolete. Walking down the street meant risking abduction or death. Such chaos became the new normal. But one day, a mafia group calling themselves KING made an announcement. "We, KING, are the ones who will establish the new <<Rules>> for you all..." Since then, KING has been expanding its influence across this dying world. What kind of monsters make up their ranks? No one has been able to gather solid intel on them. Only one thing is certain: they are absolute monsters.
