The world had stopped spinning. Or perhaps, it had spun so violently that it had inverted itself.
Hiroshi Sato gasped, a ragged, desperate sound that tore through the sudden, oppressive silence.
His lungs burned, not with the stale office air, but with something cool, damp, and overwhelmingly earthy.
Pine, perhaps? And something else, something sweet and alien, like blossoms he'd never encountered, mingled with the faint, metallic tang of ozone.
He lay sprawled on a surface that was definitely not the linoleum floor of Innovation Solutions Inc.
It was rough, uneven, and surprisingly cold against his cheek. He pushed himself up, his muscles protesting with a dull ache that seemed to permeate every fiber of his being. His eyes, still gritty from lack of sleep, struggled to adjust. There were no fluorescent lights here, only a soft, diffused glow filtering through a dense canopy overhead. Towering trees, unlike any he'd ever seen, stretched towards a sky that was a dizzying mosaic of greens and blues, pierced by slivers of what looked like sunlight.
"What…?"
The word was a croak, lost in the rustling of leaves and the distant, unfamiliar chirps of unseen creatures. He blinked, trying to clear the lingering static from his vision. The cubicle was gone.
Kenji's weary face, the stacks of bug reports, the endless hum of servers – all vanished. He was in a forest. A very, very large forest.
Panic, cold and sharp, began to prickle at the edges of his consciousness. His programmer's brain, usually so adept at processing data and identifying patterns, was short-circuiting. This wasn't a dream.
The cold dampness seeping through his thin office shirt, the earthy smell, the sharp pain in his elbow from where he'd landed – it was all too real. He was still wearing his crumpled white shirt, loosened tie, and dark trousers. His worn office shoes were still on his feet, now caked with damp soil.
He scrambled to his feet, swaying slightly. Around him, the forest floor was a riot of unfamiliar foliage: ferns with iridescent fronds, mosses that glowed faintly, and strange, bulbous fungi that pulsed with a soft, internal light. The air was thick with the scent of life, vibrant and untamed.
This was not Tokyo. This was not even Japan. This was… impossible.
His mind raced, trying to find a logical explanation. A hallucination? A stress-induced breakdown? But the sheer sensory detail, the undeniable otherness of it all, screamed otherwise. He remembered the jolt, the bursting lights, the roaring vortex. It had felt like a system crash, but he wasn't dead. He was… somewhere else.
"Isekai?" The word slipped out, a whispered, almost desperate hope. He was a programmer, yes, but he was also a product of his generation, and the concept of being transported to another world was not entirely alien, thanks to countless light novels and anime. But to actually experience it? It was absurd. Yet, here he was.
He took a tentative step, then another, pushing through the dense undergrowth. Every rustle, every distant bird call, sent a jolt of anxiety through him. He was utterly vulnerable, completely unprepared. His phone, his wallet, his laptop – all gone. He was just Hiroshi Sato, a salaryman in a fantasy world.
As he walked, a strange sensation began to manifest. It wasn't physical, but mental. A subtle hum, like a background process running in his mind, grew steadily louder. Then, a shimmering, translucent interface flickered into existence before his eyes. It was a soft, bluish-green, like a terminal window projected directly onto his retina. It was clean, minimalist, and utterly familiar in its design.
>>>
A command prompt. His breath hitched. This wasn't just a vision. He reached out a hand, and his fingers, without touching anything, seemed to interact with the ethereal display. A cursor blinked, awaiting input.
His heart pounded. Could it be? He thought of the "Reality Coding" concept he'd idly imagined, a programmer's ultimate cheat. He focused, trying to recall a simple Python command.
>>> print("Hello World")
He willed the command to execute. For a moment, nothing happened. Then, a small, glowing string of characters, "Hello World," materialized in the air directly in front of him, hovering for a few seconds before fading away.
Hiroshi stared, dumbfounded. It worked. It actually worked. His mind, his programming knowledge, was somehow directly linked to the fabric of this reality. This was beyond anything he could have dreamed. This was his cheat. This was Reality Coding.
He tried another, more practical command, his mind racing with possibilities. He needed light.
>>> create_light_source(intensity=50, color='white', duration='infinite')
A small, spherical orb of pure white light, about the size of his fist, flickered into existence beside him, illuminating the immediate surroundings with a soft, steady glow. It floated obediently at his side, casting dancing shadows on the strange trees.
"Incredible," he whispered, a genuine smile, the first in what felt like years, breaking across his face. The fear was still there, a cold knot in his stomach, but it was now overshadowed by a surge of exhilaration, a programmer's thrill of discovery.
Then, another thought struck him. His synopsis mentioned "Omni-Net." Could that be real too?
He focused, trying to access it. The terminal interface shifted, morphing into a clean, almost stark search bar.
Search Omni-Net:
He hesitated, then typed, his fingers miming the motions in the air.
Search Omni-Net: what is isekai
The search bar glowed, and then, in a flash, a list of results appeared below it. They weren't web links, but concise, information-rich snippets.
Isekai (異世界): A literary genre in which a character is transported from their ordinary world to a new, fantastical, or alternate world. Often involves a "cheat" ability.
Common Isekai Tropes: Reincarnation, summoning, truck-kun, god's blessing, OP abilities, harem, nation-building.
Survival in an Isekai: Varies greatly by world. Key concerns: food, water, shelter, hostile creatures, magic systems, local customs, currency, language.
Hiroshi felt a laugh bubble up, a slightly hysterical sound. It was real. All of it. He had been isekai'd, he had an OP ability, and he had access to a universal search engine. The sheer absurdity of it was almost too much to bear, yet it was the most logical thing that had happened to him all day.
His programmer's mind, now fully engaged, immediately shifted from panic to problem-solving. He was in an unknown environment, with unknown threats. What was the first thing any rational entity would do in this situation? Gather information. Organize it. Create a plan.
His first project: an Isekai Survival Guide.
He brought up the Reality Coding interface again, clearing the previous commands. He'd structure it like a Python script, a dynamic document that he could update as he learned more.

Code End
As he mentally typed, the lines of code flowed effortlessly, the syntax familiar and comforting. The interface responded instantly, compiling his thoughts into actionable commands. He could feel the guide forming, not just as text, but as a structured mental framework, a blueprint for his new existence. The display_text command brought up the compiled guide as a scrollable document within his visual interface, clear and concise.
He read through it, nodding. It was a solid start. A programmer's approach to survival. He had mapped out the known unknowns and identified the variables. Now, he just needed to gather the data.
The small orb of light he had created earlier still floated beside him, a beacon in the deepening twilight of the forest. He was alone, utterly alone, in a world that was both terrifying and exhilarating. The weight of his old life, the endless hours, the crushing pressure, seemed to dissipate with every line of code he mentally wrote. Here, his skills weren't just valued; they were a superpower.
He took another deep breath, this one filled with a strange mix of apprehension and anticipation. The survival guide was just the beginning. He had a world to explore, a reality to debug, and perhaps, a nation to build. The terminal loop of his old life was truly broken. His new program had just begun to run.
And for the first time in a very long time, Hiroshi Sato felt a flicker of genuine hope.
