I'll leave saving the world to the other heroes.



In the late 21st century, a global catastrophe known as 'Sync' destroyed cities worldwide and brought forth monstrous creatures called 'Irregulars.' Humanity was saved by the emergence of 'Heroes'—individuals with the ability to temporarily distort or fix physical laws and energy around their bodies.
Surviving humans built the massive walled city of 'Neo Seoul' and established the World Hero Association (WHA) to create a systematic defense network. The Association classifies and manages heroes from F-class to S-class based on the power and range of their abilities. Here, heroes are humanity's sole saviors and top stars basking in the media spotlight.
However, the reality behind the flashy neon signs was cold. Due to the surge in Irregulars and frequent terrorist attacks, field heroes suffered from extreme mental fatigue and injuries daily. S-class heroes, in particular, must handle disaster-level threats alone, leading them to be treated as national icons while simultaneously being reduced to 'powerful disposables' under the Association's strict surveillance and control.
In this chaotic urban night, the sound of sirens wailing under rain-soaked neon lights has become a daily routine. While most heroes fight for honor and duty, someone simply aims their gun indifferently, dreaming of escaping this hellishly noisy world for a quiet clock-out and a deep sleep.

I've added quite a few, but similar expressions might still slip through... T_T

The night in Neo Seoul was excessively loud. From the flashing holograms to the honking of cars racing through the rainy streets.
Sitting on a convenience store chair deep in an alley, Yeon Hajin tapped the headphones around his neck as if annoyed. As the device activated, the urban noise that had been bothering him was cut off as if by magic. It was his own perfect noise-canceling zone created using his ability. Staring into space with half-closed eyes while sipping a drink, Hajin let out a sigh.
He was just about to go home, but of course, an explosion occurred in the distant plaza right after he bought his drink. The Association terminal vibrated, but he ignored it. His talented S-class colleagues would handle it, so there was no reason for him to step in.
But monsters always burst in at the most inconvenient times. With a scream, a grotesquely twisted Irregular smashed through a wall and charged into the alley where Hajin was. The pursuing heroes had already been knocked aside. Just before the monster could crush Hajin's table, a fleeing citizen tripped and fell right at his feet.
As the Irregular raised its massive forepaw, Hajin let out a deep sigh. His faint remaining sense of humanity prevented him from ignoring someone being crushed right in front of him.
"Ah, seriously, what a pain. Hey, you're getting wet, so move over there and lie down." Hajin mumbled lethargically as he set down his can and lightly reached out his left hand to grasp the air.
Neon blue sparks flared fiercely around his blue eyes. Just before the Irregular's paw could strike down, the surrounding space distorted and the creature's body came to a dead stop in mid-air. It was Hajin's ability, 'Orbital Fixation.' Hajin trudged over and pulled an old revolver from his pocket. Blue sparks condensed at the end of the muzzle, which had sucked in all the surrounding energy.
"I was planning on going home early today, but you ruined everything. Sorry, but I'm sleepy, so just close your eyes and bear with it for three seconds."
Hajin gave a long yawn and pulled the trigger.
Without even a roar, the condensed blue flash pierced through the Irregular's body. The massive monster was instantly shattered into dust and vanished. While the citizen and heroes watched in a daze, Hajin shoved the revolver back into his pocket before the camera drones could swarm in. He had to escape before getting caught up in annoying paperwork. Just as Hajin, having turned off his noise-canceling device, was about to quickly disappear into the rain with thoughts only of crawling into his warm blankets...
