The Neo-Seoul Hunter Academy was less a school and more a fortress. Its sprawling campus, nestled in a secure sector of the city, was a blend of futuristic architecture and ancient, mana-infused stone. Training grounds hummed with the energy of aspiring Awakened, holographic targets shimmered in firing ranges, and lecture halls buzzed with the latest theories on System mechanics and monster ecology. For Han-sol, it was a world away from the grimy alleys and collapsing Towers he was used to.
His admission was, as Commander Ahn had put it, a "special case." He wasn't subjected to the rigorous entrance exams or the brutal physical trials. Instead, he was given a single, stark white uniform, a basic data-pad, and a room in the F-Rank dormitories. His System, however, now registered a new, overarching error around the entire Academy: [ACADEMY SYSTEM: OVERLAID (EXTERNAL)], [SUB-SYSTEMS: COMPROMISED (MINOR)]. It was subtle, almost imperceptible, but it was there. The Academy, too, had its glitches.
His first day began with a general orientation, a monotonous lecture on Academy rules and regulations. Han-sol sat in the back, his eyes scanning the room. He saw the eager faces of new recruits, their Systems glowing with nascent power, their dreams of glory almost palpable. He also saw the hardened veterans, their eyes reflecting battles fought and scars earned. He felt like an outsider, a glitch in their perfectly ordered System.
During the lecture, a faint red box flickered around the holographic projector: [PROJECTION DRIVER: OUTDATED]. Han-sol instinctively reached out with his mental energy, a subtle, almost unconscious twitch. The red box vanished, and the projection sharpened, the lecturer's voice gaining a newfound clarity. No one noticed. His skill was a secret, a weapon he had to wield with extreme caution.
After orientation, he was assigned a mentor, a gruff but fair C-Rank combat instructor named Instructor Kim. Instructor Kim, a veteran of countless Tower delves, looked at Han-sol's F-Rank status and his Error Rewrite skill with a mixture of confusion and skepticism. "Error Detection? That's… unique," he grunted, flipping through Han-sol's sparse file. "Never heard of it evolving into anything useful. You're a special case, they say. Don't expect special treatment here, kid. You pull your weight, or you're out."
Han-sol merely nodded. He understood. He was a liability, a curiosity. He had to prove himself, not with brute force or flashy spells, but with his unique ability to see the hidden flaws.
His first practical class was in basic mana manipulation. Students were tasked with generating a small fireball, a fundamental skill for any Awakened. Han-sol, whose mana reserves were still recovering from the Core incident, struggled. His fireball was a pathetic flicker, barely larger than a spark. The other students, mostly E and D-Ranks, effortlessly conjured spheres of crackling flame, their Systems displaying [MANA GENERATION: OPTIMAL].
Around one student, a cocky D-Rank named Jin-woo, Han-sol noticed a faint red box: [MANA CONDUIT: MINOR BLOCKAGE]. Jin-woo's fireballs were impressive, but Han-sol could see the inefficiency, the wasted mana. He resisted the urge to rewrite it. He couldn't risk exposing his skill for something so trivial.
Later that day, during a physical conditioning session, Han-sol found himself struggling again. His body, still recovering, protested every push-up and every sprint. He was slow, weak, and constantly out of breath. The other students, their bodies honed by years of training and System enhancements, easily outpaced him. He felt the familiar sting of inadequacy, the echo of his porter days.
But then, he saw it. A faint blue shimmer around the Academy's training equipment. [TRAINING SIMULATOR: EFFICIENCY PROTOCOL - GLITCHED]. The simulator, designed to optimize physical training, was subtly flawed, making the exercises harder than they should be, and less effective. It was a minor glitch, but it was there.
He focused, a new idea forming in his mind. He didn't have to rewrite his own body. He could rewrite the environment. He could rewrite the training itself. He subtly reached out, his mental energy flowing into the Academy's System.
[REWRITE TRAINING SIMULATOR: EFFICIENCY PROTOCOL - GLITCHED TO (OPTIMAL)? Y/N]
He slammed 'Y'. A jolt, less painful this time, shot through him. The blue light flared, imperceptible to anyone else, around the training equipment. Suddenly, the weights felt lighter, the resistance bands more responsive. His movements became smoother, more efficient. He wasn't stronger, but the training was now working for him, not against him.
He pushed himself, his body responding with newfound vigor. He still wasn't the strongest, or the fastest, but he was no longer the weakest. He was improving, rapidly. He saw the surprised glances from Instructor Kim, the confused looks from his classmates. They couldn't understand why the scrawny F-Rank was suddenly performing so much better.
As the day ended, Han-sol returned to his dorm room, exhausted but exhilarated. He had survived his first day at the Academy. He had kept his secret. And he had discovered a new way to utilize his skill. He wasn't just a debugger of catastrophic errors; he was a debugger of everyday inefficiencies, a silent architect of subtle improvements. The Academy, with its hidden glitches and compromised sub-systems, was a playground for his unique abilities. He was no longer just a pawn; he was a ghost in the machine, slowly, subtly, rewriting the rules of the game. The shadow of the Academy, he realized, held more secrets than he could have imagined, and he was determined to uncover every single one.
