The siren echoed again.
The sharp sound tore through the air, forcing everyone's attention upward.
A calm, mechanical voice followed.
"Our world has entered a new era."
The words spread across the beach, cold and deliberate.
"In the past, humanity relied on courts, laws, and institutions to judge crime. However, such systems have repeatedly proven flawed, influenced by bias, corruption, and the weight of wealth."
Uneasy murmurs spread through the crowd.
Some shifted uncomfortably.
Others fell silent.
"In this new era, judgment will no longer be left in human hands."
A brief pause.
"Nature itself shall intervene."
The words settled heavily, drawing confused looks from some, while others stiffened, as if beginning to understand.
"The Criminal Rehabilitation Center was established to remove all external influence."
Another pause.
Longer this time.
"To ensure that justice is absolute."
The voice did not rise.
It remained the same.
And yet, it felt heavier than before.
A man nearby let out a bitter laugh, the sound sharp against the heavy silence.
"You've got to be kidding…"
The announcement did not pause.
It did not acknowledge him.
It simply continued.
"All individuals present have been designated as participants."
A brief pause.
"You are now players within the Criminal Rehabilitation Trials."
The words settled deeper than before.
Heavier.
More final.
"Participants sent to the Rehabilitation Center are individuals whose crimes have been judged severe, controversial, or difficult to determine through conventional systems."
The weight of it spread through the crowd.
"Some of you stand here because your crimes caused great harm, yet you claimed remorse."
A woman collapsed to her knees, her breath breaking as if something inside her had just been exposed.
"Some of you stand here because the victims of your crimes demanded rehabilitation trials rather than traditional punishment."
Anger flashed across several faces, sharp and immediate.
"And some of you stand here because society itself could not decide what fate you deserved."
Silence followed.
Not empty.
But suffocating.
The silence did not last.
The crowd grew restless.
Voices rose, sharp and unsteady.
"This is insane!"
"You can't do this to us!"
Some shouted, anger spilling over their fear.
Others said nothing at all, their silence heavier than the noise around them.
Then the voice spoke again.
"Participants will undergo a series of rehabilitation trials."
The words cut through the chaos, forcing the crowd to listen.
"Your behavior, decisions, and survival during these trials will determine whether you possess the qualities necessary for reintegration into society."
A chill spread through the group, subtle at first, then impossible to ignore.
"The environment itself will serve as judge."
The statement lingered, sinking into them.
"But the trials are not fixed."
A pause.
"Each rehabilitation cycle differs from the last. The environment, conditions, and challenges will change."
Murmurs broke out again, uncertain, uneasy.
"Within each trial, rules exist."
This time, the voice slowed slightly.
"They will not be given."
A ripple of confusion spread through the crowd.
"They must be observed."
The air grew heavier.
"They must be understood."
A few faces tightened.
"And they must be followed."
No one spoke.
"Failure to recognize and comply with these rules will result in consequences."
The voice did not explain further.
It did not need to.
Some people began to panic, their voices rising over one another as fear finally broke through whatever control they had left.
"That means no one knows what will happen!"
"This is murder!"
"Shut up!" someone else shouted, the words sharp, desperate, as if silencing it could make it less real.
Different emotions erupted across the island, clashing and overlapping in a storm of voices and movement.
Fear.
Anger.
Denial.
Ren looked toward the chaotic crowd and noticed something.
The clothes they wore were not the same.
Some were still dressed in business suits, their appearance completely out of place on the island. Others wore simple home clothes, as if they had been taken straight from their daily lives without warning.
Which raised a question.
If they were all criminals, why were none of them in prison uniforms?
Ren lowered his gaze to himself.
The fabric clung to his skin, heavier now that he was aware of it.
He knew these clothes.
He remembered them.
A faint crease formed between his brows.
Not from confusion.
From recognition.
His memory did not return all at once.
But the feeling did.
This was what he had been wearing.
That day.
His expression stilled.
Then, just as quickly, it returned to its usual calm.
Among the shouting and panic around him, Ren remained silent.
So that was it.
They had not been taken at random.
They had been taken from moments.
Specific moments.
Then he noticed something else.
Amid the chaos, a few individuals remained calm.
Not unshaken.
But controlled.
They were not reacting.
They were watching.
Calculating.
People worth paying attention to.
There was the woman still sprawled near the shoreline, the same one who had been struck by the surge earlier. Her white blouse clung to her body, soaked through, while her dark skirt was streaked with sand. She had not moved far, as if her body had yet to catch up with what had happened.
Nearby stood a young girl, no older than eight.
She wore a simple yellow dress and small white shoes, the kind meant for quiet days and harmless outings. Yet she did not look frightened.
Her posture was relaxed.
Too relaxed.
She watched the crowd as if observing something distant, something separate from herself.
Her eyes moved slowly, taking everything in.
Then, for a brief moment, she smiled.
It was not wide.
Just small.
But it lingered longer than it should have.
A slim man stood a short distance away, covering his mouth with one hand as if suppressing a reaction he did not want others to see.
Not fear.
Something else.
He wore a wrinkled office shirt, sleeves rolled up, his loosened tie hanging unevenly around his neck. His gaze flickered across the scene with quiet interest.
Not far away, a girl wearing glasses briefly met Ren's eyes before looking away.
She wore a dark cardigan over a simple blouse, her appearance neat, controlled, almost untouched by the surrounding chaos.
And then there was the heavily tattooed man.
Broad.
Still.
His sleeveless black shirt revealed arms covered in ink, the patterns twisting across his skin like coiled serpents. Despite his imposing presence, he did not move.
He only watched.
Ren's gaze shifted again.
A man and a woman stood close together within the crowd.
The man wore a grey jacket over a dark shirt, while the woman beside him was dressed in a simple floral blouse.
Their hands were tightly clasped together.
But the moment the man noticed Ren looking in their direction, they let go.
Too quickly.
Both of them turned away, their attention shifting elsewhere, as if nothing had happened.
Ren said nothing, but he remembered their faces.
In a place like this, calm people, and secrets, were rarely harmless.
A voice echoed across the island once more.
"The first rehabilitation trial lies beyond the dense green forest."
"Equipment necessary for survival can be found in supply crates scattered across the area."
The voice paused briefly, as if allowing the information to settle.
"Participants…"
"May you find redemption and salvation in Mother Nature's embrace."
A faint mechanical hum followed.
Several black spheres emerged from hidden compartments among the rocks and trees, rising slowly into the air. They hovered above the island in complete silence, their smooth metallic surfaces reflecting the sunlight.
Thin lenses rotated across their bodies.
Watching.
Recording.
Cameras.
The trials were not only real.
They were being observed.
The island fell silent again.
Then the forest moved.
At first, it was subtle.
Leaves shifting.
Branches trembling.
Then came the sound.
Low growls echoed from deep within the dense trees, spreading across the island like a warning that could not be ignored.
The sound crept through the air, pressing against the skin, settling deep in the chest, making every breath feel tight and uncertain.
No one could see what was making those sounds.
But they understood.
Something was coming.
When the growls finally faded, the silence that followed felt worse than the noise.
No one moved toward the forest.
No one wanted to be first.
Because now, they were waiting.
The silence stretched.
Heavy.
Unbearable.
Then—
someone moved.
Panic erupted.
People rushed toward the scattered supply crates, kicking up sand as they ran.
The crates were marked in different colors.
Green for medical supplies.
Red for weapons.
Blue for food and water.
Others contained tools and basic survival necessities.
The moment people noticed the red crates, the crowd became even more frantic.
Weapons meant survival.
Several tried dragging entire crates away, only to realize they barely moved.
The containers dug into the sand, heavy and unyielding.
They weren't meant to carry the crates.
Only what was inside.
Realization spread quickly.
People pried them open instead, grabbing whatever they could.
Inside were tightly packed supplies—guns, knives, ammunition, bandages, bottled water, canned food, flashlights, rope, and various tools.
Some crates also contained backpacks, utility belts, and sling bags.
Those who found them snatched them immediately.
Without something to carry supplies, everything else would be useless.
Then confusion spread.
"Empty?!"
"This one's a dud!"
Several players had opened crates only to find them completely empty.
The panic intensified.
More people rushed from crate to crate, desperation replacing any sense of order
Ren watched the chaos quietly.
Then something caught his attention.
Not far from the crowd, a small boy with a backpack crouched beside one of the crates.
Unlike the others, he wasn't tearing it open in desperation.
He only looked inside.
Carefully.
As if inspecting something others could not see.
Then he stood and moved on.
Someone else rushed over and opened the crate he had just left.
"Damn it! Another empty one!"
Ren's eyes narrowed slightly.
The boy crouched again at another crate.
This time, he opened it.
The lid lifted, revealing stacks of canned food and sealed water bottles.
Before he could reach in, a larger man shoved him aside.
"Move, kid!"
The man immediately began stuffing the supplies into his own bag.
The boy stumbled back but did not argue.
He simply adjusted the straps of his backpack and walked toward another crate.
Ren kept watching.
Again, the boy crouched.
Looked inside.
Then stood and walked away.
Moments later, someone else opened that same crate.
"Nothing here!"
A flicker of something passed through Ren's eyes.
The boy wasn't searching at random.
He was choosing.
Every crate he left behind was empty.
Every crate he stopped at first had something inside.
And yet, when others checked, there was nothing left.
Ren's gaze sharpened.
As if the contents had vanished.
Or had never been there at all.
Ren did not know how.
But the pattern was too precise to be coincidence.
A thought crossed his mind.
Some kind of sight ability?
He said nothing.
But he remembered the boy.
In a place like this, people with unusual advantages were worth paying attention to.
Ren finally moved.
While most of the crowd fought over the nearest crates, he walked toward the ones farther away, where the chaos had yet to reach.
His eyes moved quickly across the colors.
Red.
Green.
Blue.
Weapons.
Medical supplies.
Food and water.
He stopped beside a crate and opened it.
Inside were several backpacks.
Without something to carry supplies, everything else would be useless.
Ren took one and slung it over his shoulder.
Only then did he begin selecting what he needed.
A few bottles of water.
Several sealed food packs.
A compact medical kit.
Nothing more.
Nothing unnecessary.
Finally, he stepped toward a nearby red crate and picked up a knife.
Around him, people were still shouting and shoving each other, grabbing whatever they could carry.
Some filled their arms with weapons.
Others hoarded food as if they could consume it all in a single day.
Ren ignored the chaos.
In a place like this, survival was not about taking the most.
It was about taking what you could keep.
And what you could protect.
