The beginning

Hiunet is a man who is known to all as a philanthropist and a man of culture, but his other side is not known to all but his victims. In his private quarters he is a man who tortures women and children for pleasure and his past.

Yu-mi, the only person Hiunet truly loves, is bright and idealistic, always eager to improve their joint work. Her excitement is palpable as she shares her new ideas for the website—a project that symbolizes their sibling bond. Hiunet, uncharacteristically warm during their call, encourages her efforts with a rare smile.

But when Yu-mi is alone and finalizing the update, something impossible happens.

The air grows thick. The screen begins to glitch. Symbols flash that she didn't code in. The walls shimmer—then begin to melt, dripping like hot wax. Her breath catches. The floor shifts. Her laptop heats rapidly, glowing red beneath her fingers. Before she can move, it bursts—metal and plastic shards explode outward. One piece strikes her temple.

Yu-mi falls, unconscious, into darkness.

Yu-mi's eyes flutter open. Pain throbs at the side of her head, but it's dulled by confusion. She's no longer in her room. The world around her is endless, white, empty—no horizon, no ceiling, no shadow. Just her… and silence.

She stumbles to her feet, heart pounding. In the distance, a lone figure stands, unmoving. Something about the figure draws her in. She squints—and her breath catches in her throat.

It looks like her.

Panic rises. She rubs her eyes, thinking it's a trick. But the moment her hands fall away, the figure is right there, nose almost touching hers, eyes like glass cutting into her soul.

Yu-mi screams and falls back, but her vision goes hazy. Her consciousness slips, and in that liminal space between waking and sleep, the figure speaks.

"My child… you will kill your brother."

Yu-mi's voice shakes with fury. "I'll do no such thing, you demon."

The figure smiles—but it's not wicked. It's… sad. Cold. Heavy.

"Demon?" it echoes. "I'm no such thing. I'm just doing the world a favor by eliminating that foul beast you call family."

Yu-mi lets out a shaky breath, forcing a smile.

"It's not real. Just a dream," she whispers to herself, trying to steady the thudding of her heart. "I just hit my head. That's all."

But the figure doesn't move. It stares, unblinking.

Then, in a voice both within and outside her mind, it says:

"You think this is a dream? No, Yu-mi. This is the beginning."

The figure vanishes in an instant—no sound, no trace. Just gone.

Yu-mi stumbles. Her head throbs like it's being split open. She groans, clutching it as the sterile white world begins to tilt and distort. A whisper slithers through her skull, sharp and cold:

"Hiunet must die."

"No," she gasps, shaking her head violently. "No, he's my brother. I love him. I—"

The voice grows louder. "Hiunet must die."

She tries to summon memories—him holding her hand when they were children, his rare, proud smile, the way he always called her his 'little genius'...

But the laughter returns.

Dark. Familiar. Right beside her ear.

"He will die."

Yu-mi collapses to her knees, tears streaming down as a war begins inside her mind—a battle between her devotion and something ancient, cold, and utterly relentless.

The pain reaches a peak—like her skull might crack open from the inside. Yu-mi screams silently, body trembling, as her vision flickers between white void and black nothingness.

Then—

Silence.

Just like that, everything returns to normal.

She's back in her room. The floor is intact. The walls solid. Her laptop is mysteriously whole again, screen blinking idly like nothing ever happened.

Yu-mi blinks. Slowly rises from her chair.

For a brief moment—just a second—her eyes burn with an unnatural red glow, like fire trapped behind glass.

Then they fade. Normal again. Calm. As if nothing occurred.

She looks around the room with a curious stillness. Not confused. Not scared. Just... present.

Then she softly whispers, as if testing her own voice:

"Time to work."

She sits, fingers dancing across the keyboard.

But this isn't the Yu-mi the world knows.

Not anymore.

Deep beneath the pristine walls of his mansion, Hiunet stood in silence.

The woman at his feet lay still—another "session" completed, her body marked by the evidence of his cruelty. Behind him, a small boy whimpered, curled against the wall, too scared to move.

But Hiunet didn't look at the boy.

His gaze locked on the girl in the corner—the last one left.

She sat trembling, knees to chest, face buried in her arms, rocking slightly as she sobbed.

"Please… please don't… I just want to go home…"

Her words were muffled, desperate, drowned in the thick tension of the room.

Hiunet took a slow, deliberate step toward her. Then another.

The floorboards creaked under his polished shoes.

His lips curled into a smile—not of joy, but of pure, unfiltered malice.

"Home?" he said softly, almost mockingly. "You think there's a home waiting for you now?"

The girl looked up, tears streaking her face, fear etched into her every feature.

Hiunet crouched down just enough to meet her terrified eyes.

"No one's coming for you."

And just as he reached out his gloved hand—

A sudden chill swept the room. The air tightened.

For the briefest moment, Hiunet paused… a strange sensation pricking the back of his neck.

A presence.

He slowly stood, turning his head toward the shadows—his grin fading into a look of vague irritation.

Something had changed.

But he didn't know yet… that his beloved sister was no longer entirely his.

The knock echoed through the chamber like a scream in a church.

Hiunet froze mid-step, eyes narrowing toward the door. That chill again. That unwelcome presence brushing the back of his mind. But no—he wouldn't show weakness. He smoothed his sleeves, fixed his collar, and walked calmly to the door.

When he opened it, his eyes softened at the sight.

Yu-mi.

Her smile radiant, just like always. The sister he loved. The only one he cared about in this rotting world.

"Yu-mi?" he asked, forcing a casual tone. "Why are you here?"

Her smile stayed, but her eyes… something about them felt wrong.

Then she spoke—and it wasn't her voice.

"I'm here to kill you."

The words were clear. Cold. Absolute.

Hiunet blinked, caught off guard. He gave a short laugh, masking the flicker of unease in his gut. "Very funny," he murmured, patting her lightly on the head.

But she didn't blink. Didn't flinch.

That smile faded, replaced by a blank, emotionless stare. Her head tilted slightly.

Hiunet's hand slowly moved toward the back of his coat, toward the hidden holster at his waist.

This… wasn't Yu-mi.

And for the first time in years—Hiunet hesitated.

"Who… are you?" he said lowly, his fingers brushing metal.

Yu-mi stepped forward, her voice now a haunting whisper wrapped in static:

"I am justice… for every cry you've silenced."

Her eyes flared bright red—like the last embers of a fire that had waited far too long to burn.

Hiunet's hand gripped the gun. Finger on the trigger.

He didn't hesitate.

He fired.

But before the bullet could even leave the chamber, a foot crashed into his ribs—crack—the sound of bones snapping echoed in the room like thunder.

Hiunet's body folded, dropping to his knees as he gasped, blood dripping from the corner of his mouth. His eyes wide. Disbelieving.

"You…" he croaked, the world spinning.

But he never finished the sentence.

Yu-mi spun with unnatural speed and slammed her foot into the back of his head.

His body lurched forward—launched off the ground from the sheer force—just in time to meet her fist.

A devastating uppercut to the jaw.

The sound of impact was like a gunshot.

Hiunet flew across the room, crashing into the wall with a sickening thud before slumping to the floor in a mangled heap.

For a second, there was only the hum of silence.

Then footsteps.

Measured. Calm.

Yu-mi approached, her expression unreadable. Eyes dimmed to normal now—but her presence was anything but human.

She stood over him, looking down at the man the world admired, the monster she had once called "brother."

His limbs twitched, trying to move. Trying to understand.

And somewhere, deep inside her, the real Yu-mi screamed—fighting for control.

But the being only smiled through her lips.

"You're weaker than I expected," it said. "But don't worry… I'm just getting started."

Hiunet groaned, blood pouring from his mouth as he tried to crawl away. Bones broken, vision blurred, pride shattered.

But it was too late.

Yu-mi stepped over him like he was nothing more than garbage.

With inhuman ease, she grabbed him by the head—fingers digging into his scalp like iron claws. His feet dangled inches above the floor, his body limp, too broken to resist.

Her eyes glowed red again. Brighter this time. Like twin suns at the end of all things.

"This… is your end."

Hiunet's eyes widened. There was no plea. No final clever line. Just terror. Raw and choking.

Yu-mi pressed her free hand to his chest—right over his heart. Her fingers sparked with strange symbols, ancient and shifting.

She began to speak—foreign words, harsh and rhythmic, echoing with ancient power.

"Atravan… Ves'tar… Ki'Morta... Elimination."

A blinding light erupted from her hand.

Hiunet didn't scream.

He didn't even have time to.

His body imploded—instantly reduced to a cloud of blood, bone, and shredded flesh. Bits of him hit the floor like rain. What remained of the feared man was now nothing more than minced meat soaking into the tiles.

The room fell silent.

Yu-mi stood in the middle of the mess, completely still. Not a drop of blood on her.

Her eyes dimmed.

She blinked.

Confusion flickered on her face.

"...Brother?" she whispered, voice trembling.

Then she looked down.

And saw what she had done.

Yu-mi blinked rapidly, heart hammering in her chest. The red glow was gone from her eyes.

The power had faded.

But in front of her—what remained of Hiunet—was unrecognizable. A shredded mass of flesh and blood, soaking the floor, staining her shoes.

She stumbled back with a scream, trembling violently.

"What… what have I done?"

She spun, clutching her head, tears flooding her face. Panic rose like bile. She didn't know how she got here. She didn't remember the fight. Only fragments. Only the voice.

She ran—blinded by shock—through the halls of his private quarters, stopping only when she collapsed in a corner, hugging her knees.

And then it hit her.

The voice. The void. The figure.

It all came rushing back.

"I killed my brother…"

She sobbed, face buried in her arms, whispering curse after curse between ragged breaths. Her mind spiraled. She looked at her blood-soaked hands.

"I should die too."

Driven by desperation, she sprinted down the narrow stairway to the basement—anywhere to escape herself.

But then…

She stopped cold.

The air was heavy. Thick with rot.

And there—lying on the ground—was the mutilated body of a woman.

In the corner, two small figures shivered, wide-eyed, terrified. The same children Hiunet had tortured, now frozen in silence.

Yu-mi stared.

She looked at the body.

Then the children.

And in that moment, everything inside her broke open.

This was who he was.

The monster in her memories wasn't a lie. She hadn't destroyed an innocent man. She had stopped a monster. Saved lives.

Her hands trembled for a new reason.

She dropped to her knees beside the kids, her voice barely a whisper. "You're safe now… I'm going to get you out."

She gently unshackled them, wrapped them in whatever cloth she could find, and led them out through the back tunnels—into the cold night.

Not as a sister. Not as a killer.

But as a survivor.

And then she vanished, disappearing into hiding—haunted, hunted, but finally walking her own path.
