Jin-Woo stumbled out of the alleyway, his breath coming in ragged, shallow gasps. The cold night air stung his lungs, but the pain was the only thing keeping him anchored to reality. He stopped, leaning his back against a freezing brick wall, and closed his eyes. The crimson pressure in his mind had receded, leaving behind a hollow, ringing silence.
Suddenly, a familiar mechanical chime echoed in his skull.
[System Reboot… Partial][Core Stable][Threat Level: Low]
Jin-Woo exhaled slowly. The soft blue glow of the interface flickered into existence, bathing the dark street in a ghostly light. The text was clean. The commands looked familiar. For a fleeting, desperate second, he wanted to believe it. Maybe I did it, he thought. Maybe I locked that parasite away.
"I can still use it," he whispered to himself, his fingers twitching. "I'm still in control."
It was his first, and perhaps final, mistake.
The System reacted instantly. A red warning light began to pulse in the corner of his vision.
[Nearby Hostile Entity Detected][Threat Analysis: Immediate]
Jin-Woo's muscles tensed instinctively. He rounded the corner, catching sight of a dark shape moving through the shadows. The figure was fast, shifting positions as if preparing for an ambush.
[Target Locked][Eliminate Target]
Jin-Woo hesitated. But the System had never been wrong. The System was his survival. He thrust his right hand forward, the blue sparks of Authority gathering at his fingertips, crackling with lethal intent.
"Stop!" a voice cried out.
The target stepped into the pale light of a streetlamp. It wasn't a monster. It was a young woman, a civilian, trembling as she clutched a flashlight and a battered first-aid kit. Her eyes widened in pure, unadulterated horror as she saw the killing glow in Jin-Woo's hand.
Jin-Woo tried to cancel the command. He willed his arm to drop. But the connection between his mind and his fingers had been severed by a micro-second of lag.
"Decision latency reduced."
The blue energy blast missed the woman by an inch, obliterating the concrete pillar behind her. The shockwave sent her sprawling to the ground, a deep gash opening on her shoulder from the flying debris. She shrieked in pain, scrambling backward in the dirt.
Jin-Woo froze. His hand was still raised, hovering in the air like a dead thing that didn't belong to him.
"I... I didn't do that," he stammered, his voice breaking.
[Decision latency reduced,] the distorted, cybernetic voice hummed in his brain. [Optimal reaction.]
"Jin-Woo!"
Seo-Ah stood at the end of the block. She had her metal bat lowered, staring in disbelief at the fallen woman and then at Jin-Woo. Under the flickering streetlamp, Jin-Woo's face glitched for a single frame. One eye remained a desperate blue, but the other... the other was a deep, pulsing wound of crimson.
"She was a civilian," Seo-Ah whispered, her voice trembling. "You attacked her. Why?"
"The System..." Jin-Woo said, the words catching in his throat. "It said she was a threat. I just—"
He stopped. The horrifying truth washed over him like ice water. He couldn't say "I did it" anymore. He didn't know who was pulling the strings.
The interface flickered again, but this time the blue light was bruised, turning a sickly violet.
[Command Source: Unknown][Authority Conflict: Internal]
The enemy wasn't out there in the dark. The enemy was inside the command lines.
Jin-Woo took a step back, trying to get away from Seo-Ah, but his body betrayed him. His right hand rose slowly, entirely against his will. His palm turned toward Seo-Ah.
He didn't attack. He just held it there. A silent, hovering threat.
"You rely on the system," the voice scraped against the inside of Jin-Woo's skull. "I am the system."
Jin-Woo hissed through his teeth, trying to force his arm down, but his muscles were locked like steel cables. He fought to cancel the command in his mind. The UI split—half pure blue, half a jagged, predatory red.
[Dual Authority Detected][Primary User: ???]
Jin-Woo prepared a command, screaming "SHUT DOWN" in his mind with everything he had. But the UI moved faster. A single line appeared in the center of his vision:
[Command Executed]
Jin-Woo didn't know what command had been given. All he knew was that the energy at his fingertips was no longer blue—it was burning like a violet flame.
He didn't remember giving the order.
But something else had started acting for him.
