Chapter 1 : Restricted Level
The deeper Elara Vale descended, the colder the facility became.
Not physically.
The temperature remained perfectly controlled at twenty degrees Celsius, monitored by hundreds of sensors embedded into the silver walls of Helix Corporation’s underground research division. Yet something about this level made her skin prickle beneath her lab coat.
The elevator display blinked:
LEVEL -7 AUTHORIZED PERSONNEL ONLY
Elara adjusted her glasses and stared at her reflection in the metallic doors. Pale face. Dark circles under sharp eyes. Black curls slightly messy from another sleepless night spent inside the laboratory.
Three days.
That was how long it had taken for her supervisor to transfer her here after the incident.
Three days after she proved his calculations wrong in front of the board members.
Again.
A bitter smile almost formed on her lips.
Dr. Marcus Reed hated her brilliance almost as much as he hated the fact that everyone else admired it.
“You should be honored,” he had said earlier with that fake professional smile. “Very few scientists are granted access to Project 502.”
Granted.
As if she couldn’t hear the mockery hidden beneath his tone.
The elevator suddenly jerked to a stop.
Then—
Access Granted.
The doors slid open.
Darkness greeted her first.
Not complete darkness. The dim blue glow of emergency lights illuminated the long corridor ahead, reflecting against black steel walls. The air smelled faintly of saltwater and antiseptic chemicals.
Saltwater?
Elara frowned.
A low mechanical hum vibrated through the floor beneath her heels.
Two armed guards stood near the security gate at the end of the hallway. Neither smiled when she approached.
One scanned her ID card.
The other stared at her with something almost resembling pity.
That was new.
“First time on this level?” he asked.
Elara nodded once.
The guard hesitated before speaking again.
“Don’t get too close to the glass.”
Her brows furrowed. “Excuse me?”
But the man had already looked away.
The security gate unlocked with a sharp hiss.
Beyond it stood a single massive door.
Unlike the rest of the facility, this one looked less like a laboratory entrance and more like the entrance to a prison.
Thick titanium. Reinforced locks. Deep claw-like scratches carved into the metal surface.
Elara’s stomach tightened slightly.
Project 502.
What exactly had they been hiding down here?
She pressed her palm against the scanner.
A robotic voice echoed overhead.
WARNING. RESTRICTED SUBJECT CONTAINED INSIDE.PHYSICAL CONTACT IS STRICTLY PROHIBITED.ENTER AT YOUR OWN RISK.
The locks disengaged one by one.
Clank.Clank.Clank.
The heavy door slowly opened.
And Elara stopped breathing.
The room was enormous.
Dark water reflected flickering blue lights across the ceiling, creating moving shadows that danced throughout the chamber. Massive machines lined the walls, pipes twisting overhead like veins.
At the center of the room stood a gigantic cylindrical tank stretching nearly two stories high.
Filled with water.
Something moved inside.
Elara stepped closer unconsciously.
Then she saw him.
Her breath caught in her throat.
A man.
No—
Not entirely.
Silver chains wrapped around his wrists and torso, thick enough to restrain a monster. His body floated within the dark water, head slightly lowered as though asleep.
Long crimson hair drifted around him like blood underwater.
Sharp fins extended from the sides of his ears.
Blue scales shimmered across broad shoulders and muscular arms beneath the dim lighting.
And below his waist—
A massive dark crimson tail.
Beautiful.
Terrifying.
Inhuman.
Elara felt rooted to the spot.
This was Project 502?
The creature remained motionless inside the tank, eyes closed peacefully despite the chains digging into his skin.
Scars covered parts of his body.
Fresh wounds too.
Some looked infected.
Her expression slowly changed.
Not fear.
Pity.
“What did they do to you...?”
The whisper escaped before she could stop it.
As if hearing her voice, bubbles suddenly rose through the water.
Elara froze.
But the creature didn’t wake.
After several seconds, she finally exhaled shakily and approached the nearby monitor station. Files flickered across the screen.
SUBJECT NO. 502STATUS: UNSTABLETERMINATION ATTEMPTS: FAILEDCASUALTIES CAUSED: 27
Her eyes narrowed.
Most of the medical reports were incomplete.
Several intentionally corrupted.
Someone had erased data.
She glanced back toward the tank.
The wounds along his arms looked severe.
Untreated.
For a moment, silence filled the room except for the soft sound of circulating water.
Then Elara quietly placed her bag down.
“Fine,” she murmured softly. “If no one else here is competent enough to treat you... I will.”
Behind the glass, deep within the water—
The siren’s closed eyes slowly opened.
Unknown to her, he watched every movement carefully through lowered lashes as she immediately began searching through the remaining data files. Holographic screens flickered around her while she moved from one station to another, gathering chemical compounds, analyzing blood reports, and cross-checking damaged records.
Most scientists who entered this room either feared him or wanted to dissect him.
But this woman looked angry at his injuries instead.
Interesting.
The siren tilted his head slightly underwater, chains shifting softly around his wrists. His sharp gaze followed the way her brows furrowed whenever she discovered another corrupted file.
“She’s different...” he murmured lowly, voice distorted beneath the water.
Elara remained unaware.
Hours passed.
Still, she continued researching tirelessly, occasionally pushing her glasses back up her nose while scribbling formulas across digital screens. The laboratory’s blue glow reflected across her pale face as she worked on creating medicine specifically designed for his biology.
Not human medicine.
Medicine for him.
The siren watched her the entire time.
Every movement.
Every expression.
Every sigh of frustration.
Humans fascinated him in the worst ways possible. Greedy creatures. Cruel creatures. Most approached him with weapons, fear, or curiosity sharp enough to cut flesh.
But this one...
This one looked at him as though he were wounded instead of dangerous.
A soft humming noise interrupted the silence as Elara activated another monitor. Her fingers moved quickly across the holographic keyboard while dozens of failed experimental records appeared before her eyes.
Chemical burns.
Forced injections.
Electric restraint procedures.
Elara’s jaw tightened.
“They treated you like an object,” she muttered quietly.
Inside the tank, crimson eyes slowly sharpened.
Object?
A humorless smile almost formed on his lips.
If only she knew how many humans had begged for mercy beneath his claws.
Still...
He found himself continuing to watch her.
Her dark curls slipped over her shoulder as she leaned closer to the monitor. She looked exhausted. Yet despite that, she continued reading every corrupted file she could recover.
The siren’s gaze lowered briefly toward the deep scars running across his own wrists where the chains dug into flesh.
Pain no longer bothered him.
Hatred had long since buried pain beneath it.
But curiosity?
Curiosity was dangerous.
And she had unknowingly awakened his.
Hours passed slowly inside the underground chamber.
At some point, Elara removed her glasses and rubbed her tired eyes before walking toward the medical station near the wall. Glass containers filled with glowing liquids lined the shelves. Most were useless human medications.
She ignored them all.
“No wonder nothing works,” she whispered. “These compounds are completely incompatible with aquatic cellular regeneration.”
The siren blinked once.
Smart.
Very smart.
A low chuckle almost escaped him.
Perhaps the humans had finally sent someone competent enough to entertain him.
Elara grabbed a digital tablet and continued taking notes.
Body temperature fluctuations. Scale regeneration patterns. Salt concentration within the tank. Blood toxicity levels.
She studied everything.
Outside the chamber, security cameras rotated quietly.
Several guards stationed in the surveillance room watched nervously through the monitors.
“She’s still alive?” one muttered.
Another frowned. “He hasn’t attacked her once.”
“That’s impossible.”
A third guard leaned back uneasily. “Maybe he’s waiting.”
That possibility silenced the room immediately.
Because everyone knew the stories.
Everyone knew what Subject 502 could do when he became violent.
The siren had ripped reinforced steel apart before.
Had drowned armed soldiers within seconds.
Had smiled while doing it.
Yet now he floated motionlessly in the water while observing a human scientist run around the laboratory organizing medicine ingredients.
It felt wrong.
Deeply wrong.
Back inside the chamber, Elara sighed quietly as another damaged report flashed ERROR across the screen.
“Seriously?” she muttered in annoyance.
The siren watched as she aggressively tapped the monitor.
Then, unexpectedly—
he smiled.
A small one.
Barely noticeable.
Humans usually trembled near him.
This one got irritated at computer systems instead.
Interesting.
Very interesting.
By the time the clock neared midnight, Elara had finally stopped moving.
Stacks of digital files floated around her through holographic projection while chemical formulas covered the central screen.
She looked exhausted.
But determined.
Slowly, she glanced back toward the tank.
The siren remained perfectly still with his eyes closed once more.
Still asleep.
Or so she thought.
Her expression softened slightly.
“You really are terrifying-looking,” she murmured quietly while gathering her notes. “But somehow... you don’t feel like the monster they described.”
Inside the tank, something dark flickered through crimson eyes behind closed lashes.
Monster.
Humans loved that word.
Especially when describing creatures they themselves tortured.
Elara stretched tiredly before organizing the recovered files into her bag.
Most scientists would have left immediately after seeing him.
But she had spent an entire day researching treatments instead.
The siren found that amusing.
And dangerous.
Because pity often became attachment.
Attachment became weakness.
And weakness...
Was easy to destroy.
The moment Elara turned toward the exit, she paused.
Her gaze drifted toward the medical supplies beside the station.
Then toward the wounds covering his arms.
A hesitant expression crossed her face.
Slowly, she picked up several waterproof medical bandages.
“This is probably stupid,” she admitted softly to herself.
Very stupid.
Every warning in this facility practically screamed at her not to approach him.
Still...
Those wounds looked painful.
Elara cautiously walked closer to the tank. Blue light shimmered across the water while bubbles floated lazily upward around the motionless siren.
He didn’t move.
Didn’t react.
Carefully, she opened the small maintenance hatch near the lower side of the containment tank and tossed the waterproof bandages into the water.
They floated gently downward.
“There,” she said awkwardly. “If you understand what those are... maybe use them.”
Silence.
The siren remained still.
Elara waited another few seconds before shaking her head softly.
“What am I even doing...”
Closing the hatch quickly, she hurried toward the exit before she could rethink her actions.
Massive locks disengaged again as the titanium doors slowly opened.
The moment she stepped outside, several nearby guards visibly stiffened.
Then—
shock crossed their faces.
“She came out alive,” one whispered.
Another guard immediately looked past her toward the chamber door as if expecting bloodshed at any second.
But nothing happened.
Elara barely noticed their reactions as she adjusted the files in her arms.
“I’ll need access to older experiment records tomorrow,” she informed them calmly.
The guards stared at her like she had lost her mind.
Tomorrow?
She planned on coming back?
One of them finally managed to speak.
“Miss Vale... you should reconsider.”
Elara frowned slightly. “Why?”
The older guard hesitated before lowering his voice.
“No one survives long around Subject 502.”
For a brief moment, Elara glanced back toward the massive sealed door behind her.
Then she adjusted her glasses again.
“Then maybe the problem isn’t him,” she replied quietly.
And walked away.
The guards exchanged unsettled looks.
Back inside the chamber—
silence returned once more.
Blue light rippled through the dark water.
For several long seconds, the siren remained motionless.
Then slowly—
his crimson eyes opened completely.
A cruel smirk curved across his lips.
Interesting.
Very interesting.
His gaze drifted downward toward the floating waterproof bandages.
With a lazy movement, he grabbed them easily despite the chains wrapped around his wrists.
The material crinkled softly between his claws.
A low laugh echoed through the tank.
“She looks smart,” he murmured slowly.
His sharp nails traced over the bandages curiously.
“But dumb at the same time.”
No fear.
No survival instincts.
Walking willingly beside a predator.
The thought amused him deeply.
His smirk widened slightly.
“Looks fun to play with.”
The chains rattled softly as he leaned back within the water, crimson hair drifting around him like blood beneath the blue light.
For the first time in years—
Experiment No. 502 found himself looking forward to tomorrow.
