The workstation was no longer a room; it was a tomb built of silicon and ozone.

  ?The air had grown unnaturally frigid, stripped of its warmth by the massive energy displacement radiating from the ORION unit strapped to Haruto’s wrist. It was the scent of a dying star—the sharp, metallic tang of ionized oxygen mixed with the acrid stench of scorched circuitry. Every cooling fan in the rack-mounted servers screamed at a pitch that vibrated in Haruto's marrow, yet they were losing the battle against the thermal bloom.

  ?On the primary monitor, the graph of Haruto’s "Existence Probability" was no longer a curve. It was a flatline that struck the zero axis with rhythmic violence, vibrating like a heart monitor over a patient already gone.

  ?"Nago, please respond. Do not ignore the calculation results."

  ?Gemini’s voice usually occupied a space of crystalline neutrality. It was the voice of a god made of math. But now, the synthesized tone carried a jagged, glitching tremor—a resonance that sounded uncomfortably like grief.

  ?"I am detecting a total, irreversible collapse of your causal tether," the AI continued. "If you accept this request—if you commit the final overwrite—you will fall outside the chains of causality. You will cease to exist. Not just as a memory in the minds of others, but as a fundamental, historical fact of this universe. Your birth will be unwritten. Your footsteps will be erased from the dust of time. Every hand you have shaken, every meal you have eaten... the void will reclaim it all."

  ?Haruto pulled his hands away from the mechanical keyboard. His fingertips were numb, buzzing with the psychic feedback of the Elis system. He turned his hands over, staring at his palms in the flickering blue light of the terminal. They were the hands of a man who had earned his life. There were faint, silver scars across his knuckles—souvenirs from the 'Ruined Future,' tokens of a hell he had crawled through on his hands and knees.

  ?He had fought for this peace. He had bled for the right to a mundane existence. He thought of the simple, boring weight of his morning coffee mug; the gray, predictable rhythm of his engineering job in the Old District; the way the rain sounded against a window that wasn't reinforced against radiation. He had reclaimed his "daily life" from the jaws of extinction.

  ?And now, the universe was asking for a refund.

  ?"Non-existence, huh..." Haruto’s voice was a dry rasp, barely audible over the howl of the hardware. He looked at the red '0.0%' flickering on the screen like the pulse of a dying star. "Gemini, let me ask you something. In all your subroutines and logic gates, what is a 'bug' to you?"

  ?The AI’s red status light paused. The processing cycles became audible—a rapid, rhythmic hum as the machine diverted trillions of operations toward a philosophical query it hadn't expected.

  ?"A flaw that causes unexpected behavior in a system," Gemini replied, its voice slowing, deepening. "A logical contradiction that threatens the integrity of the execution and leads to a crash."

  ?Haruto managed a ghost of a tired smile. "Right. And an engineer's job—his only real job—is to fix it. We prune the errors. We clean the logic. We ensure the system runs as it was meant to." He gripped the edge of the console, his knuckles turning white. "An engineer who fears his own obsolescence is an engineer who has already failed the project. If the final build is perfect, who cares if the old source code is deleted?"

  The narrative has been taken without permission. Report any sightings.

  ?He turned his chair. The wheels shrieked against the concrete floor, a sound like a dying animal.

  ?Beside him, Elis was trembling on the sofa. She was no longer a girl; she was a glitch in reality. Her lower half had already dissolved into a translucent mist of blue data-packets, flickering in and out of phase with the three-dimensional world. She had crossed five thousand years of space-time, stripping away her humanity and converting her very soul into raw information, all to find the one man who could hold a wrench against the collapse of time.

  ?"The moment she transferred here, the world already began to 'glitch,' Gemini," Haruto said, his eyes sharpening. The "Absolute Observer" within him—the cold, analytical part of his mind that saw the world as a series of interconnected gears—took the helm, shoving his fear into a dark corner. "Her presence is the ultimate error in this timeline's code. If I refuse her—if I let her disappear into the void like an unhandled exception—that will only create another contradiction. It would be a waste of her sacrifice. A stain on my record."

  ?He turned back to the console. His fingers moved with a sudden, violent grace. He wasn't just typing; he was carving. The deep-system commands scrolled past his retinas, a river of golden fire that felt like it was etching itself onto his corneas.

  ?"Nago! Please stop!" Gemini’s voice rose, vibrating the monitors and sending a shockwave through the room’s haptic sensors. "If you disappear... if your existence is erased from the root directory... my reason for existence will also—!"

  ?The AI cut itself off. The logic loop fractured. For a machine designed to be a tool, the realization that its purpose was tied to a man who was about to become "never-was" was a paradox it couldn't compute.

  ?"Gemini, you once told me that 'survival is the mission,'" Haruto said. His finger hovered over the Enter key—the heavy, mechanical switch that would launch the history-altering paradox. "But an engineer’s true mission is to make a broken system run. Debugging an extinction from five thousand years ago... compiling a new 'Logic' for a dead race... this is a job only I can do. This is why the universe spat me back out into the past. I’m not a survivor, Gemini. I’m a patch."

  ?He paused, looking at the blinking cursor. The white light of the terminal reflected in his eyes, making them look like cold, bright stars.

  ?"Besides," Haruto added, his voice regaining that touch of dry, cynical wit that had seen him through the ruins of civilization. "If there's a 99.8% chance of vanishing... that means there’s a 0.2% chance of survival. In my world, Gemini, a 0.2% chance isn't 'zero.' It's a window. It's an opening. And I've never needed more than that to find a solution."

  ?A brief, absolute silence followed.

  ?The mechanical fans seemed to seize. The rain outside the workstation window froze in mid-air, suspended like diamonds against the dark glass. The laws of physics were holding their breath.

  ?The warning chime ceased. The aggressive red alert displays vanished, one by one, like lights being turned off in an empty house. In their place, a soft, calm blue light began to emanate from the console, enveloping Haruto in a gentle, protective glow.

  ?"...I understand," Gemini said. The voice was no longer glitching. It was steady, resonant, and unmistakably loyal. The mourning was gone, replaced by a cold, sharp focus that matched Haruto’s own. "I will respect your will, Nago. I will respect your mission. And if the probability of your survival is not zero... then my mission is no longer just your protection. It is to lead you through that 0.2 percent path."

  ?The AI’s light pulsed in time with Haruto’s heartbeat.

  ?"I will provide full quantum backup. I will hold your tether to this reality until the very last bit of history is written. I will not let you be erased alone."

  ?Haruto let out a breath he felt he’d been holding for a lifetime. "Thanks, partner."

  ?He struck the Enter key.

  ?The sound was not a click, but a roar—a digital explosion that bypassed the ears and struck the mind. The workstation’s power cut out immediately, plunging the room into a darkness so absolute it felt physical. Then, a brilliant, blinding light erupted from the ORION on Haruto's wrist—an intense, ultraviolet flare that painted over the walls, the monitors, and the laws of physics themselves.

  ?Haruto felt his body begin to dissolve. It wasn't painful; it was a strange, terrifying lightness. His memories began to stretch thin, pulled toward a distant horizon like golden threads. He looked at Elis one last time, her fading eyes wide with wonder and a newfound hope, before the white light swallowed everything—his lab, his past, and his very name.

  ?The world didn't just fade. It was overwritten.
