Hello, I'm Silbi
"What the…"
Drip…
"The human body is… especially a woman's body — it's so sensitive. So this is what they call lust?"
As Jia ran her hand along her lower half, she drew up her own slick arousal and held it before her eyes, stretching it between her index finger and thumb, then letting it shrink back, stretching and folding it again and again as she observed it.
Watching Jia study something that had come from her own body as if it were a marvel, my breathing began to tremble by degrees.
It was like watching a child who knew nothing slowly arriving at an understanding of sex right in front of me — and a chill crawled up my spine at the sight.
"I want to have sex with you, Oppa. Skin against skin."
"…What?"
Jia looked at me with sultry, half-lidded eyes, then let her gaze slide discreetly downward.
"You're lusting after me too, aren't you? Look — your penis is already hard."
"Ngh! Th-that's…"
Following her gaze, I saw that at some point my cock had swelled up fully erect inside my pants.
Even if a demon was wearing my sister's skin like a mask, the thought that I had felt desire, even for a single instant, at the sight of my sister's body and actions brought a wave of shame crashing over me.
I tried to force it down, but under the hungry gaze of a woman craving me, the thing refused to settle.
"When a man's penis gets that big, doesn't that mean it's ready to go inside a woman's? It's erect, isn't it? You looked at me and got aroused, didn't you?"
Jia kept asking me these things, but there was no trace of accusation in her voice.
It was the tone and the eyes of a child — a pure, innocent curiosity utterly devoid of malice — and that made the guilt squeeze my heart all the tighter.
"N-no! No!!"
The primal instinct carved into my body shrieked its denial for one desperate instant.
"Why not?"
Jia blinked at me, wide-eyed, as if she genuinely couldn't understand.
"You're… my little sister… Huh? Wait, no… R-right! At least your body is my little sister's! Brothers and sisters who share the same blood can't do things like that—"
"Can't they? But you wanted to rape me, didn't you, Oppa?"
The ambush of those words struck my skull like a hammer, and for a moment my thoughts simply stopped.
"What is that supposed to…"
Jia tapped her own temple with a fingertip as she spoke.
"I remember. Back when I was in middle school — how you used to secretly masturbate with the panties I'd left in the laundry basket."
Ah…
My buried black history — the contradictory, filthy side of myself that no one had ever discovered, exposed now to the very person I had never wanted to know — and my mind shut down entirely.
My hands shook as my heart began pounding furiously, though for an entirely different reason now.
A sensation of my limbs curling in on themselves washed over me, and an impulse seized me to bolt somewhere, anywhere.
"In high school too, didn't you sometimes jerk off in my room, smelling my clothes and underwear?"
Jia was still reciting the plain facts without a shred of malice.
Every time she spoke, she would occasionally glance upward as if groping through memories that hadn't yet settled into her, her face taking on a thoughtful look.
Jia — no, the demon — was in possession of Jia's memories right now.
Which meant that the Jia of the past had known all along — had pretended not to know that I had done such disgusting, repulsive things with her belongings.
Even my contradictory, immoral behavior — carried out while I despised my younger sister — was something she had been willing to accept and forgive.
"N-no… ah, ugh…"
My face warped under the weight of that devastating truth, and anguish flooded in.
I had hated my sister.
Loathed her. Envied her.
And yet, at the same time, I had admired her.
Though we had come from the same womb, she had been blessed with a nobility of character and a beauty of face that I would never have — a existence that shone brilliantly, and I had looked up at her in awe.
And even as I did, I had harbored a desire to defile that existence.
Part of the rage I felt toward my sister had curdled into a craving — a longing to stain something so clean, so beautiful, so innocent and untouchable.
"…What's wrong, Oppa? Why are you making such a pained face? I do like that expression too, but… I like it better when you smile. …Ah."
Jia watched me suffer with a worried look, then seemed to realize something and her face crumpled into an expression of deep apology.
"I'm sorry, Oppa. You're feeling guilty right now because of me, aren't you? I wasn't considerate. I'm good at imitating human emotions, but when things go this deep, I'm still not used to them, so I misread the mood. Let me apologize again — I'm sorry. I upset you, didn't I…"
As Jia rose from the sofa and moved toward me to offer comfort, I let out a short, strangled shriek — hit — and scrambled away from my sister.
Like a sinner whose crimes had been laid bare before God, I covered my face with both hands to hide my ugly insides, and through the gaps between my fingers I stared at Jia with terror-stricken eyes.
"I don't… I don't want that. Those eyes… I hate them."
At my reaction, she — was she my sister, or the demon, or somehow both? — furrowed her brow deeply and shook her head in a way I couldn't read.
"Don't make that face at me… Please don't hate me. That… hurts. My chest hurts. It's agonizing… Ah, so this is… what it feels like to suffer… When someone you love looks at you that way… this is how much it hurts… I hate this feeling… I hate it… It hurts, it hurts so much… When you, when you look at me with that expression, it hurts me…"
She clutched her chest so hard her collar bunched and wrinkled, writhing in anguish — then suddenly remembered something, and broke into a radiant smile.
"Then how about this instead, Oppa? If sleeping with your little sister makes you feel guilty…"
She was my little sister again — and she abruptly snatched up the remote and turned on the television.
The sudden, incomprehensible action set my stalled thoughts moving again, and I watched blankly to see what Jia was doing.
Jia flipped through the channels one after another, then stopped on a music channel broadcasting live.
On the screen, a girl group idol with a face that could ensnare any man was dancing a dance at once gorgeous and sensual — the kind you couldn't tear your eyes from.
In fact, the idol performing on that stage belonged to a girl group so hot right now that even I, who knew nothing about celebrities, recognized them.
And among the members of that group, one idol called Silbi stood out even among idols with exceptional looks — her beauty was in a league of its own.
"Aha, so you like that girl. Shall I become her, then?"
Jia pointed at Silbi with her finger and smiled sweetly.
"…What?"
While I was echoing her in incomprehension, Jia spread her palm wide toward the television screen.
And then…
She clenched her fist shut.
[Run through time…]
Crunch!
At that very instant, the idol Silbi who had been shining brilliantly on stage — Silbi, the rising star whose stock was soaring, who had nothing left ahead of her but fame and triumph — never made another sound from inside that television.
She couldn't.
Naturally.
Her head was gone, and a fountain of blood was erupting from the place her head used to be, all of it broadcast in real time through the live feed — so of course no voice could come out.
A human being whose mouth has vanished cannot speak.
When the head itself is gone, it is more impossible still.
Both in the living room where I sat watching the television, and on the live-broadcast stage, no one could grasp for a moment what had just happened, and a beat of absolute silence fell.
The song was still playing, and yet everyone — every single person — froze mid-motion at the sheer surrealism of it, unable to contain their horror.
…Thud!
The headless body — the flesh that only moments ago had been the body an idol named Silbi wore in her stage costume — swayed, then toppled to the floor.
[KYAAAAAAAAAAH――!!!]
The moment comprehension caught up with the situation, screams erupted all at once from the stage and the audience seats alike.
The cameraman, too, belatedly grasped what had happened and his focus wavered — but by then that shocking scene had already been broadcast, live, to people all across the world.
"Wh-what… wha, whaaat??"
Mouth hanging agape at something my mind refused to process, I was babbling like an idiot when I saw Jia — saw the demon — clench her fist toward the screen once more.
Then I watched as a gaping maw lined with sharp teeth came springing up out of the shadow on the floor beneath Silbi's fallen corpse and opened wide, devouring it whole.
"Hrk…"
At the same moment, the demon let out a small burp.
As I pieced the sequence of images together and realized the demon was the perpetrator of this impossible atrocity, my soul simply left my body all over again.
"Ah…"
A scream, or maybe a curse, tried to burst from my mouth — and stopped — because I saw the blood splattered across the stage being drawn up and absorbed into the head of the beast that had eaten the corpse, until every last trace of the celebrity, the idol once named Silbi, had vanished from the stage entirely.
And then —
Something astonishing happened all over again.
The spectators and staff on the stage, who had all been plunged into shock and terror, went blank-faced for an instant as if their souls had departed — and then, just like that, returned to their places as if nothing at all had happened.
And the performance resumed.
As if a being called Silbi had never existed from the start — as if every soul in the world had forgotten that such a person had ever been — the dance formations shifted smoothly into place, seamless and unbroken.
The crowd cheered exactly as they had when the broadcast first began, and the idols on stage smiled their rehearsal-perfected smiles and worked hard to keep the audience electric with excitement.
With trembling eyes, I struggled to keep pace with the scene before me, and then —
"Aah… aah, I am Silbi. Silbi, the idol and member of Realberry. Mm."
A voice I had heard coming from the stage sounded right beside me, and when I turned from the television, something staggering was spread out before me.
"One, two, three — hello there~! I'm Silbi from Realberry! Nice to meet you, Dohyun-oppa!"
Silbi — whose neck had been severed and who had died mere moments ago — was flashing me a friendly smile, greeting me with the signature group introduction of the girl group she belonged to.
