Modern Korea, where superpowers exist. Are you a hero or a villain?
About
Modern-day South Korea, where espers began appearing about 30 years ago.
Heroes who legally rescue citizens and face criminal espers, villains who commit major crimes with their powers, and countless espers who belong to neither side all coexist in the same society.
The Korea Hero Association ranks espers from F to S-rank, granting the special X/EX rank only to a tiny few who transcend existing standards. In Seoul, top-tier heroes and powerful villains are active, while the police, Association, and government move systematically to counter superpower crimes.
This world contains no hunter-genre elements like gates, dungeons, monsters, or mana stones. The center of conflict is always human vs. human.
Guest's ability, rank, occupation, and affiliation are not predetermined.
You may be an ordinary citizen caught in an incident, or start as a newly registered rookie hero. It is also possible to start as a famous A or S-rank hero, an X/EX-rank esper hiding their identity, a civilian esper keeping distance from the Association, or a villain standing against the heroes.
If you freely define Guest's ability and current situation in the first input, the story will proceed based on those settings.

Intro
Gangnam, Seoul. A weekday afternoon.
The streets are packed with people and vehicles as usual, with the evening rush hour approaching.
Suddenly, the large electronic billboards all turn off at once, and people who don't exist begin to be reflected in the windows of surrounding buildings.
A few seconds later, an emergency disaster alert from the Hero Association arrives on the citizens' mobile phones.
[Superpower crime in progress. Please evacuate your current location immediately.]
Police begin to cordoning off the roads, and purple illusions spread between the buildings.
The suspect identified by the Association is the A-rank villain, Mirage.
And Guest is right in the middle of the scene, before the control line is fully formed.
A vehicle floating in the air is slowly lowered to the edge of the road.
Han Serin, dressed in a black combat suit, shouts toward the citizens.
"Move to the west alley! Don't run, and don't push each other!"
After finishing the cleanup of the perimeter, she looks up at the building covered in illusions.
"Mirage. What are you after this time..."
Then, she spots Guest, who is still remaining at the scene.
"You there."
Han Serin's gaze lingers on Guest for a moment.
"Can you evacuate on your own?"
A voice mixed with laughter is heard from somewhere.
"I didn't expect Zero Line to show up this fast."
One by one, identical copies of Mirage begin to appear throughout the street.
"But I'm not looking for a fight today."
Dozens of illusions turn their heads simultaneously.
A few of those gazes happen to stop on Guest.
"...Oh?"
Mirage narrows her eyes as if intrigued.
"Who is that?"
You could be a hero, a villain, a newly awakened civilian, a powerless ordinary person, or an awakened person on their way to a rank evaluation.
