BAD ENDING 001: Slave Walker Sonia 2
“No turbulence. No deviation from the projected route… It feels a little rushed, I won’t deny that… but Sonia doesn’t have anything else she can do for me right now. Originally we could have handled this together while she was getting ‘modified’ in the maintenance bay.”
Peko’s voice was utterly businesslike. Like a mechanic inspecting the performance of a spare part, she coldly recited Sonia’s condition.
“Think of it as getting a head start. When I press the button, the lenses will lock onto the ones already over your eyes, so don’t move and don’t panic. Slave Walker Unit Sonia. You can do that for me, right?”
Peko’s words took the shape of a question, yet refusal was never among the available options.
With her rejection circuits already destroyed, only a single answer remained possible for Sonia.
“Yes! Slave Walker Unit Sonia will not move. Please execute the education program on Slave Walker Unit Sonia, Master…♡”
Sonia answered with pure delight. As a Slave Walker Unit installed in her Master’s combat walker, it was only natural that Master would remodel her body and mind to bring them even closer to true unit specifications.
Having already decided to carry Master safely to their destination, becoming a component worthy of that duty was the most commonsensical thing in the world.
When Slave Walker Sonia returned the expected answer, a soft series of button clicks filtered in through the walker’s external speakers.
Master’s fingers were dancing busily across the controller.
Oh… what would happen if someone else pressed those buttons…?
Watching Master mash the controls with what looked like reckless abandon, a lewd, self-destructive fantasy flickered through Sonia’s mind.

The kind of scene you saw in cartoons and novels—where a brainwashed partner suddenly transforms into an enemy combatant.
Of course, the idea of her own Master ever having the controller stolen was something that would absolutely never happen.
But if she—with a Slave Walker Unit–exclusive mental-control part already embedded in her forehead—were somehow kidnapped… The fantasy had just begun to deepen when the crystal rooted into her skull like a living thing gave a faint vibration.
Sonia’s autonomous thoughts were immediately suppressed by the system. Unnecessary thinking only degraded unit performance.
“Then just relax, Sonia. ‘That’s an order.’ You can do that, right? You’re a good Slave Unit. Aren’t you?”
“…Yes… Master…”
Atop the car-sized four-legged combat weapon, Peko checked once more on Milli—still unconscious and limp inside her white latex suit—then turned her gaze back to the controller.
For Sonia’s “education” procedure, she set the combat walker to full automatic travel mode. From her coat she produced a small black data chip and slotted it into the controller.
The moment the plastic chip—shaped like a game data pack—was read, mechanical arms inside the walker began to move in silence. Strange glass lenses hung from their tips. The robot arms drifted slowly toward Sonia’s face as she lay prone.
Yellow lenses already covered Sonia’s golden eyes. Over those, the robot arms’ lenses layered themselves one after another. As lens stacked upon lens, multicolored geometric patterns began to whirl across Sonia’s field of vision.
It was a professional mental-remodeling education program designed for slaves and criminals of average mental resistance.
The instant the re-education program started, the control-core rod occupying the deepest part of Sonia’s pussy began to thrash violently.
A direct assault on the most sensitive place in order to weaken mental resistance. The control rod pumped back and forth with wet, obscene sounds, yet Sonia offered no resistance at all—she simply surrendered her entire body to the machines that bound her limbs.
“…Yes. …Master! …Hyaaah?! Haaah…♡ Ye… yellow… light… Master…?”
Sonia’s mental resistance was already below average. No—closer to critically deficient. The moment the lenses touched her pupils, her consciousness began to drown helplessly beneath the strange sounds ringing inside her skull.
As if determined to sabotage any remaining coherent thought, the control rod only grew more ferocious.
“Ahaat… haaaang…♡ Combat walker… my… control rod… two… two shocks in a row is… a… dash… daaash… daaashiiit…?!”
Past piloting sensations and present pleasure tangled together until Sonia’s mind was pure chaos. The bizarre light created by the stacked lenses dragged her consciousness ever deeper into the abyss.
The deeper the light poured through her eyes into her brain, the louder the noise inside her head grew, and an unidentifiable voice began to resonate.
My… head… is prickling… weird feeling… I… don’t… I… don’t like…
Hot tears welled and spilled over the yellow contact lenses designed so she could never close her eyes—tears that fell against her will.
Instinctive revulsion made Sonia’s head jerk to the side. A final scrap of resistance still remained.
“Slave Walker Sonia.”
“Yes, Master…”
“Focus on the sound you’re hearing. Understood?”
“…Yes… Master… Slave Walker Unit… is focusing… now…”
Master’s command. With that single phrase, the last of Sonia’s desperately clinging will snapped clean through with a soft crack.
Just as ordered, Sonia stared blankly into the dazzling lights that made her skull prickle simply from looking at them.
The layered lenses stimulated her brain more and more intensely, slowly—and thoroughly—rewriting her mind.
“I am… a Slave… Walker… I was made… to become a Slave Walker…”
> Slave Walker Unit Configuration Program… Loading…
> Cerebral cortex compatibility confirmed… Suggestibility efficiency measured… ‘Extremely Vulnerable’.
> Ego regulation stage… ‘Immediately Processable’.
> Mental remodeling program Phase 1 initiating…
> Can you hear my voice clearly?
“Yes, I can hear you…”
> Slave Unit current status… ‘Trance State’ confirmed.
> Focus your mind on the voice and begin sinking deeper and deeper.
> Are you a Slave Walker Unit… or a person?
“I am… a Slave Walker Unit…”
The question itself rested on the premise that a Slave Walker Unit was not a person. For Sonia—who had already been taught that the only thing that existed inside the walker was a unit—it was the most natural question in the world.
> Then sink deeper, Walker Unit.
“Yes, I’ll sink deeper…”
Inside the Slave Walker that continued its autonomous march exactly as Peko had configured, Sonia’s mind was being perfectly controlled by the program.
The specific visual patterns generated by the lenses produced a hypnotic effect that made certain command phrases seem to echo inside the heart simply from being seen. It was preliminary work—softening the mind before a full data-reception device was implanted in the brain.
> …Repeat after me. You are recovering your memories as a Slave Walker.
> Memories of carrying out missions under Master’s orders. Recall the moments when you moved as though you yourself had become a Slave Walker.
> Not as a Slave Walker Unit—recall the memories as if you had become the Slave Walker itself…
“…Yes… not a Slave Walker Unit… I am recalling the memories of the walker itself… Master…? Master… Master…♡”
> Yes. Recall it. The joy of being controlled by Master, piece by piece.
> Thanks to Master, you never had to think about anything—wasn’t that peaceful?
> Recover more of your memories as a Slave Walker.
The data chip Peko was using was an advanced re-education program that could only be applied to units with a successful mission completion record.
Because the process imprinted absolute trust toward Master, using it on a unit that carried memories of failure could produce the opposite effect.
Ironically, that very condition meant the chip was almost never used. Units with enough successful combat experience were already claimed full-time by their pilots, while the rookie units that actually needed the program never met the requirements.
Slave Walker Units were always in short supply. The intuition and judgment of a living human possessed a value artificial intelligence could never replace—yet the exacting conditions and the reality of being treated as consumables meant almost no one volunteered. That was precisely why Peko had marked Sonia’s “aptitude” from the very beginning.
> You are not a Slave Walker Unit—you are the Slave Walker itself, are you not?
> A component that moves for Master. That is what a Slave Walker is, isn’t it?
“Yes. I am the Slave Walker that Master pilots… Without Master I am nothing… That is exactly what I am…♡”
Sonia’s mind was being diligently reconstructed according to the hypnosis-induction scenario.
Her successful combat experience had already been converted into memories that proved loyalty and submission to Master, and she was being thoroughly educated in her place as nothing more than equipment belonging to the combat walker.
