In a world where power determines survival, Kairo Voss is nothing but a weak human, struggling to get by in a society ruled by the strong. Without abilities, without status, and without hope, he is treated as an outcast in his own school and ignored by the world around him.

But everything changes when he awakens the Nightborn System—a mysterious power that grants him the ability to evolve beyond human limits. With Relic Arms, Void Artifacts, and newfound abilities at his disposal, Kairo is thrust into a brutal world of vampires, military conflicts, and an impending alien invasion.

Hunted by powerful factions, drafted into a war he never wanted, and forced to make impossible choices, Kairo must rise from the bottom to become something more than human. But evolution comes with a price… and the deeper he delves into his power, the more he realizes he may not be the only one chosen by the system.

In a world where the strong prey on the weak—will Kairo become the predator or the prey?"

Nightborn Evolution

The air burned. Smoke and fire twisted through the wreckage as the three Omega Variants closed in. Kairo's body was failing, his team was battered, and their strongest fighter—Rhea—was trapped.

But his mind focused on one thing.

"Arin," Kairo said quietly. "How fast can you set up a controlled explosion?"

Arin's eyes flickered with realization. "You want to bring the whole place down on them?"

"Not just them." Kairo's gaze hardened. "Us too."

"Maybe," he admitted. "But right now, we don't win in a straight fight."

Arin gritted her teeth, already pulling a small detonator charge from her belt. "I can overload the remaining power cells in sixty seconds."

Lena adjusted her grip on her rifle. "Then we just need to stay alive for sixty seconds."

He vanished in a blur of speed, appearing inches from Kairo, his fist a black blur—

Kairo barely dodged. The sheer force of the strike shattered the ground, sending shockwaves through the rubble.

Lena and Arin fired, bullets ricocheting off Valkir's reinforced body. The second Variant—a female with golden eyes—flashed forward.

She kicked Lena's rifle clean out of her hands and slammed a fist into Arin's gut, sending her flying.

The third Variant, the giant, stomped forward, grabbing a massive steel beam.

Kairo ducked at the last second—the impact obliterated the ground where he stood.

Kairo's movements sharpened. He spun around, his Void Claws igniting, slashing at Valkir's exposed side.

For the first time, he felt resistance.

Valkir growled, stepping back in shock. His healing was still working, but Kairo had finally hurt him.

Lena took the opening, grabbing a plasma grenade from her belt.

The explosion engulfed the golden-eyed Variant, sending her flying into a wall.

Arin, still coughing from the earlier hit, pressed a final button.

"Kairo…" Her voice was weak, but determined.

She had ripped off her cybernetic arm.

Underneath, wires and exposed flesh sparked wildly. She held something—a glowing core.

"The charge won't be enough," she said. "But this?"

She was holding her own power source.

"If I overload this…" Rhea coughed, blood staining her lips. "…it'll wipe out everything within a mile."

Lena's eyes widened. "That includes you!"

Rhea smiled. "Then you better not waste it."

Kairo's fists clenched. His mind screamed at him to stay, to help, to fight.

Kairo sprinted through the crumbling tunnels, Lena dragging Arin beside him.

Behind them, the entire facility exploded.

A shockwave of fire and debris chased them, tearing apart steel and stone.

Kairo pushed forward, lungs burning, every step fueled by the one thought in his mind—

Kairo gasped as he crawled out of the rubble. His vision blurred, body trembling.

Lena and Arin coughed beside him, covered in dust and blood.

Everything—wiped from existence.

For a long time, none of them spoke.

Because deep down, he already knew.
