Chapter 6: The Faceless Hunter

The silence of the Oblivion shattered like glass.

The hallways vibrated. The lights flickered. And on the surveillance screens, a figure advanced with a chilling slowness.Tall. Slim. Covered in a dark suit of armored polymer. Faceless. Only a smooth, white mask, with no eyes or mouth.

HK-01.But in the records, it was called something else.

ZERO.

Z3R0 spoke quickly, broadcasting to all lower-level shelters.

"We have a total breach. Black Code. Maximum priority. If you see him, do not engage. Do not try to reason. Do not shoot. Run."

Aiko and Kael were no longer running. They stood frozen in front of a camera where the image flickered, revealing the enemy slowly approaching, as if he had no rush to kill.Only absolute certainty.

"Is that your... brother?" Kael asked, gun loaded in his hand.

Aiko couldn't answer. There was something about that figure... something she couldn't explain. An echo in her chest. A tremor that wasn't fear, but recognition.

He was like her too.But broken. Empty.

"Zero was the first functional subject," Z3R0 explained through the communicator. "He has no memories. No identity. No voice. Only orders. He was the greatest success and the most monstrous failure of Project Hikari."

"Why did they send him now?" Kael asked.

"Because you unlocked the file. You're no longer a shadow. Now they know you're alive."

Screams started echoing from the lower levels.Short. Brutal.As if death had no time to waste.

Kael and Aiko moved through the tunnels, helping evacuate the few who could still walk.But every corner smelled of desperation.Every step felt like they were being followed.

And then...

Silence.

A door slammed shut by itself.

The metal froze.

The air became static.

And there he was.

ZERO.

Aiko saw him face-to-face for the first time.Or rather, face-to-mask.

He said nothing. Made no gesture.He simply extended a hand toward her.

As if calling her home.

Kael fired.

Three shots.

Direct hits to the chest.

ZERO didn't even flinch. He just slowly turned his head toward him.

And then, hell broke loose.

He moved like a living shadow. Silent. Fearless.Kael barely managed to block the first blow. It hurled him into a wall, cracking concrete.

Aiko screamed his name, ran toward him, and without thinking... struck.

A punch.A surge.

ZERO flew several meters back.

Kael looked up at her from the ground, blood dripping from his mouth.

"How... did you do that?"

Aiko was panting. Her arm trembled.She had felt... a force inside her. Like a spring that released only when she was about to break.

ZERO stood up slowly. His mask now cracked.

He made no sound.

But something in his posture changed.

Now he recognized her.

She was the next one.HK-07.

And he wouldn't stop until he deactivated her.

"We have to go," Kael said, crawling toward her.

"No. We can't keep running."

"You can't beat him. Not yet."

Aiko looked at him. Her body shook. But her eyes were ablaze.

"Then he won't kill me today."

And for the first time, she chose to fight.

Not as Aiko, the broken girl.

But as HK-07, the forgotten anomaly.
