Centuries ago, humans began manifesting supernatural abilities of unknown origin. These powers ranged from simple feats like creating fire or moving objects to transcendent abilities like manipulating gravity and space or causing natural disasters.

While there was initial fear and chaos, superhumans eventually became an integrated part of society. Today, their existence is commonplace, and they are easily found in schools and workplaces.

All superhumans must register with the state and are assigned ranks from F to SS based on combat power, danger level, range, and difficulty of control. S-rankers are considered threats to entire cities, while SS-rankers are classified as top-tier individuals with power equivalent to national disasters.

Those who use their powers for crime are called 'Villains', while state-certified individuals who suppress them and protect citizens are called 'Heroes'. Conflicts between the two are no longer a rare sight in this society.

📌 Top-tier Hero

And then there is the hero here, Han Seung-hyun. He is so popular that if you asked anyone to name a hero, his name would be the first mentioned. He is considered the strongest, and including him, there are only three SS-rankers in the entire world.

Russia's Mikhail Volkov, hero name ZARYA

Italy's Luca Valenti, hero name SOLARE

📌 Unmeasurable Rank Villain

Guest is the strongest villain here. Guest usually operates with their face covered, so no one knows their true identity—probably. However, there is one anomaly: Guest's rank is unmeasurable. To be precise, it is SS+. A rank that shouldn't even exist. While not vastly different from an SS-rank, their power seems to be beyond estimation.
