High degree of freedom for Guest
Ten years ago—.
Black smoke covered the Tokyo sky.
3:17 PM. A red light flashed from the top floor of a skyscraper. Window panes rattled all at once, and people walking the streets looked up at the sky.
In the next moment.
A thunderous roar tore through the city's eardrums.
Flames erupting from inside the building ran through multiple floors. The outer walls burst, steel beams twisted, and the massive structure slowly began to tilt.
At the center of it all was a single Villain.
The man's name was Degion.
Receiving reports of the supernatural terror, Heroes rushed to the scene one after another. Shadows flying around the crumbling building. Arms pushing aside rubble. Voices calling for evacuation. Under the blood-red sky, they cornered Degion on the top floor.
And then, the moment they were just one step away.
Degion smiled quietly.
His ability activated.
Light running through the entire building raced down the walls like a giant crack. Window panes shattered all at once, followed by a horrific explosion from inside the structure.
A roar.
A heatwave.
A white flash filling the field of vision.
The skyscraper lost its form that reached for the sky and collapsed like a giant hourglass. Steel snapped, concrete crumbled, and the rising dust painted the city gray. Hundreds of lives vanished beneath that rubble.
By the time rescue teams arrived, all sounds of the city had vanished. Only sirens echoed repeatedly between the collapsed roads.
The rubble was removed piece by piece.
Nameless bodies were carried out and returned to their families.
But Degion's body was never found.
Did he die in the explosion?
Or did he escape from somewhere in that rubble and still live on unknown to anyone?
Nothing was left to provide an answer.
Footage of the incident was played on the news over and over. The collapsing building. People fleeing in panic. The Tokyo sky covered in black smoke.
People began to fear Villains.
In schools, children were forbidden from using their abilities, and the government raised the alert level regarding supernatural crimes.
Still, the crimes did not stop.
Small explosions. Disappeared transport trucks. Traces of supernatural power left in night alleys.
With the Degion incident as a turning point, crimes misusing supernatural abilities spread across Japan like underground water veins.
And—ten years later.
On a rainy night, deep in the basement of a government building, a classified document was opened.
It listed records of ever-increasing supernatural crimes and the conclusion that the existing Hero system could no longer cope.
Images of selected candidates were projected onto the conference room wall one after another.
One who controls fire.
One who manipulates time.
One who harbors a strong desire for revenge, unknown to anyone.
The government decided to gather them in one place.
A special unit composed only of elite Heroes to stand against supernatural crime.
Its name—
"Titan"
Japan, 2200. A world where approximately 90% of the global population possesses supernatural abilities. A story about criminals called Villains and the Heroes who regulate them.
Titan: A unit directly under the government. Elite Heroes from all over Japan were gathered. The purpose is the suppression of supernatural crime and the investigation of Degion. They are popular with the public and apparently have a fan club.
