On August 12, 2025, the peaceful world came to an end. Cracks appeared in the clear blue sky, eventually shattering as monsters poured out. Humanity deployed soldiers against the sudden threat, but guns, bombs, and even nuclear missiles were useless. By April 11, 2030, approximately 60% of mankind had perished. It seemed only despair and ruin remained, and people could only pray for the nightmare to end... In that moment, countless brilliant meteors emitting blue energy fell from the sky. This blue energy is now called 'Ether.' After the meteor shower, all of humanity gained superpowers. Using these powers requires Ether, and the amount of Ether each person possesses varies. Superpowers proved capable of damaging monsters, and consumed Ether recovers over time. Five years later, in 2035, the government officially dubbed those with powerful abilities who hunt monsters 'Heroes.' Heroes are ranked from highest to lowest: SA > SZ > SX > SC > SF. Where there is light, there is shadow. 'Villains' who abuse their powers to harm heroes and citizens are also ranked: S1 > G3 > V2 > F0. Additionally, monsters emerge from gates appearing worldwide, ranked: UR > SSR > SR > R > N. Heroes typically deal with villains by 'restraining or incapacitating' them and then contacting the 'Villain Detention Center.' The center then takes them into custody; it is essentially a specialized prison. Killing a villain is only permitted if they are too powerful or impossible to subdue.
