Darkness had a sound.
It wasn't silence.
It was breathing.
Slow. Mechanical. Endless.
---
Drip.
Drip.
Drip.
---
A dim red light flickered above a narrow chamber of reinforced glass and steel.
Inside A boy sat chained to the floor.
---
His name… was Diablo.
---
His wrists were bound in black restraints etched with faintly glowing runes.
His ankles were locked in place.
His body—covered in scars, both fresh and old.
Not the kind of scars earned in battle.
The kind inflicted.
Repeatedly.
---
He didn't move.
Didn't speak.
Didn't react.
---
Outside the chamber, behind a thick observation panel, several figures stood watching.
White coats.
Cold eyes.
No hesitation.
---
"Subject D-13," one of them said, adjusting a glowing tablet.
"Heart rate stable. Regeneration speed… increasing again."
Another leaned forward, frowning.
"That's impossible. We increased the dosage."
---
A third voice spoke—calm, precise, controlled.
"He's adapting."
---
The room fell silent.
All eyes shifted to the man standing at the center.
Tall.
Composed.
Dangerous.
---
Dr. Kael Virex.
---
"He shouldn't be alive," one researcher muttered.
Kael didn't respond immediately.
His gaze remained fixed on the boy.
Studying.
Calculating.
---
"No," Kael said quietly.
"He shouldn't."
---
Inside the chamber—
Diablo's eyes opened.
---
Crimson.
Faint.
But unmistakable.
---
The chains rattled… just slightly.
---
"Begin the next phase," Kael ordered.
---
Alarms flickered softly as the chamber shifted.
From the ceiling, mechanical arms descended—each carrying syringes filled with dark, unnatural liquid.
Not human.
Not pure.
---
A mixture.
---
Vampire essence.
Werewolf serum.
Demonic ichor.
---
A forbidden fusion.
---
The needles drove into Diablo's skin.
---
His body tensed.
But he didn't scream.
---
Not anymore.
---
The liquid entered his bloodstream.
For a moment—
Nothing happened.
---
Then—
---
His heartbeat spiked.
Violently.
---
THUD.
THUD.
THUD.
---
Veins darkened beneath his skin, spreading like cracks across glass.
His fingers twitched.
Muscles tightened.
Bones… shifted.
---
"Energy levels rising—!" a researcher shouted.
"Containment might not hold!"
---
Kael didn't move.
"Observe."
---
Inside the chamber—
Something changed.
---
Diablo's breathing slowed.
Not weakened.
Controlled.
---
His eyes… focused.
---
For the first time—
He wasn't enduring.
---
He was aware.
---
The chains around his wrists creaked.
Not from struggle.
From pressure.
---
Crack.
---
A faint fracture appeared along one of the restraints.
---
The nearest scientist froze.
"…Did you see that?"
---
Kael's eyes narrowed.
"Interesting."
---
Inside the chamber—
Diablo tilted his head slightly.
As if listening to something no one else could hear.
---
A whisper.
Not outside.
Inside him.
---
Something ancient.
Something hungry.
Something… awake.
---
His fingers curled slowly.
Deliberately.
---
Crack.
---
The chain snapped.
---
For a second—
No one moved.
No one breathed.
---
Then—
---
"All units—!"
---
Too late.
---
Diablo stood up.
---
Unsteady.
But not weak.
---
The remaining chains dragged behind him.
His head lowered.
His expression empty.
---
Then—
He took a step forward.
---
The chamber trembled.
---
The glass—
Reinforced.
Layered.
Runic.
Unbreakable—
---
Shattered.
---
Silence collapsed into chaos.
---
Alarms screamed.
Red lights flooded the facility.
Guards rushed in.
Weapons drawn.
---
"Contain the subject!"
---
Diablo stepped out of the chamber.
Barefoot.
Unarmed.
Unafraid.
---
A guard lunged first.
Fast.
Trained.
Precise.
---
Diablo moved.
---
Not fast.
Not flashy.
---
Efficient.
---
The guard hit the ground.
Didn't get back up.
---
The others hesitated.
Just for a second.
---
That was enough.
---
Something flickered in Diablo's eyes.
Not rage.
Not fear.
---
Recognition.
---
He understood something now.
---
Power.
---
Not given.
Not borrowed.
---
Taken.
---
He moved again.
---
Faster this time.
---
Too fast.
---
The hallway filled with echoes of movement, impact, and collapsing bodies.
Metal bent.
Concrete cracked.
The air itself felt… heavier.
---
Outside—
The scientists stared in horror.
---
"This isn't control," someone whispered.
---
Kael remained still.
Watching.
---
"No," he said softly.
---
"This… is evolution."
---
Inside the chaos—
Diablo stopped.
---
Not because he was tired.
Not because he was hurt.
---
Because he heard something.
---
Footsteps.
Different.
Heavier.
Stronger.
---
He turned slowly.
---
At the end of the hallway—
A massive figure stood.
Armored.
Silent.
Eyes glowing faintly behind a reinforced mask.
---
Grave-9.
The execution unit.
---
For the first time—
Diablo smiled.
---
Not with joy.
Not with madness.
---
With understanding.
---
A challenge.
---
And deep within him—
Something answered.
