The sky above Mega City Helios was never truly dark. A dull crimson glow stretched across the horizon where the Rift Zones bled into the world, staining the clouds the color of old iron. Towering alloy walls surrounded the city like the ribs of a giant skeleton, reinforced with plasma cannons that hummed in a constant, low register. Beyond those walls lay a different world — a world of mutation where humans were no longer at the top of the food chain.
Inside the outer district of Helios, the slums were packed with rusted steel houses stacked on top of one another like unstable towers of scrap metal. Neon signs flickered weakly in narrow streets crowded with scavengers, hunters, and desperate survivors trying to live another day. Life here was cheap. People disappeared overnight, and nobody asked questions.
Kai Ren moved quietly through the alleyways, his worn backpack hanging loosely from one shoulder. His clothes were stained with dust and dried blood that had long since lost its color. No one stared. In the slums, stains like that were normal. His eyes stayed calm and observant, sweeping every shadow as he walked. Every scavenger learned the same lesson sooner or later: the weak died first.
He stopped at a reinforced iron gate leading outside the city. Beyond it stretched a wasteland of broken buildings, collapsed highways, and twisted steel towers. The Outer Rift Zone. Dangerous ground for ordinary citizens — but for scavengers like Kai, it was simply survival. A guard inside the checkpoint booth glanced up lazily as he approached.
"Another scavenger run?"
Kai nodded and slid a worn metal tag across the counter. The guard scanned it. A short electronic beep confirmed his identity. The gate groaned open. No warning followed. The guard had seen too many scavengers leave and never return.
The world outside the walls felt colder. The wind carried a metallic scent mixed with decay. In the distance, broken skyscrapers leaned at unnatural angles while faint purple mist leaked from dimensional fractures scattered across the ruins. These fractures were called Rifts. Twenty years ago they had appeared without warning, tearing open space itself. From them came monsters — creatures that were neither animal nor alien, but something twisted between the two.
Humanity had nearly lost the planet during the first Rift outbreak. Entire cities vanished within weeks. The only reason civilization survived was because scientists discovered something hidden inside those creatures: Gene Fragments. Strange pieces of DNA capable of merging with human cells and pushing the body far beyond its natural limits. Strength, speed, endurance, and reflexes could all be enhanced. Humanity entered the era of Gene Evolution.
But evolution came at a price. Gene fragments were rare and controlled by powerful corporations and military organizations. Only the wealthy could afford the strongest upgrades. For people in the slums, survival depended on scavenging the dangerous Rift Zones and selling whatever mutated materials they could find.

Kai stepped deeper into the ruins, his boots crunching softly on broken glass and concrete. The Rift Zone was quiet now. Quiet never lasted long.
A faint growl echoed from inside a collapsed building nearby.
Kai froze. His hand moved slowly toward the short combat blade strapped to his thigh.
Moments later, the creature appeared.
A Mutant Bloodhound.
Its body was twice the size of a normal dog, muscles bulging beneath grey skin reinforced by unnatural bone plates. Purple veins pulsed beneath its flesh while glowing eyes locked onto Kai. Its nose twitched. It had already caught his scent.
The Bloodhound lunged.
Kai twisted instantly, sidestepping as the creature slammed into the concrete where he had been standing. Cracks spread from the impact like a spider's web. Fast. Too fast for an ordinary human.
Kai stepped forward and drove his blade downward. The weapon pierced the creature's neck, but the Bloodhound refused to fall immediately. It snapped its jaws toward his arm, teeth scraping dangerously close to his sleeve. Kai wrenched the blade free and struck again — deeper this time. The creature collapsed with a choking growl and finally went still.
Silence returned to the ruins.
Kai exhaled slowly and steadied his breathing. Even small mutant beasts could kill an unmodified human. He crouched beside the corpse and began working quickly. From his pouch he pulled a small extraction tool and carefully opened the creature's chest cavity.
After a moment of searching, the tool struck something solid. A small, crystal-like organ embedded near the creature's spine — glowing faintly, pulsing with strange energy.
A Gene Core.
Rare. Very rare.
Kai wiped the blood from the crystal and sealed it inside a protective container. Even a damaged gene core could sell for enough credits to survive another week.

But before he could stand, the ground beneath him vibrated slightly.
At first he thought another monster was approaching, but the feeling was different — it came from below. A crack appeared in the concrete nearby. Then another. The floor collapsed inward, revealing a narrow tunnel hidden beneath the ruins.
Kai stared into the darkness as cold air drifted upward from the opening. Something deep inside the tunnel emitted a faint blue glow.
Curiosity could be deadly in the Rift Zone.
But sometimes danger meant opportunity.
Kai activated the flashlight on his wrist and climbed carefully into the tunnel. Dust covered the walls, and strange metallic structures protruded from the ground like fragments of an ancient machine. None of it looked human-made.
The deeper he walked, the brighter the glow became.
Eventually the tunnel opened into a small underground chamber. At its center lay a smooth metallic sphere — roughly the size of a man's torso — embedded firmly in the stone floor. The object hummed softly, releasing steady waves of blue light that cast shifting shadows across the walls.
Kai stepped closer.
The sphere reacted instantly.
Its surface unfolded like a mechanical flower, revealing interlocking rings of dark metal and pulsing crystal veins beneath. Before Kai could step back, a beam of concentrated light shot directly into his chest.
Pain exploded through his body. His muscles locked as his vision blurred. Something cold spread through his veins, rewriting the structure of his cells from the inside out.
Then a mechanical voice echoed inside his mind.
[Ultra Gene Evolution System — Activated]
[Host DNA Compatibility: Confirmed]
[Binding Sequence: Initiated]
Kai collapsed onto the ground as waves of energy surged through him. Something deep inside his DNA was changing. Evolving.
Far above the ruins, hidden satellites belonging to powerful corporations suddenly detected a new and impossible energy signature rising from beneath the Rift Zone.
The birth of something unknown.
Something dangerous.
Kai Ren did not yet understand what had happened to him.
But from this moment forward, his evolution had begun.
