BAD ENDING 003: D-Class Lewd Partner Drone Sonia 1
Flushed scarlet with shame and arousal, Sonia finally resolved to lay bare her most humiliating secret with her own lips.
It was the moment the last fraying thread of her reason snapped helplessly before the hunger for pleasure.
The other self raging inside her body — Sonyaroid's relentless whispers — tangled with a twisted craving to serve the friend and object of her admiration standing right before her eyes, and together they short-circuited Sonia's every thought.
LEWD DRONE SONIA MODE ACTIVATE
Just forming the words made her chest tremble with shame. And with that trigger phrase, Sonia decided she would thoroughly explain to the other self inside her — Sonyaroid — every concrete action Luce would have to perform to reduce her to a perfect possession, a fully functional component.
It was surrender. And at the same time, it was Sonia's own choice — the path to realizing her deepest desire.
"I thought a Sonyaroid would know everything, but there are things you don't know! No matter how deeply I got… um… a little too absorbed in that virtual reality experience and ended up trained as a lewd drone! Just shouting Lewd Drone Sonia Mode Activate! in front of my face doesn't turn me into Sonia-with-a-lewd-drone-identity, you know!"
Her voice quavered thinly with embarrassment, yet an irrepressible excitement ran through the tremor. On top of that, a strange sense of superiority at having caught Sonyaroid's blind spot made Sonia's tone far more assertive than usual.
Once the dam broke, the words would not stop. Sonia began exposing her most intimate shame in even finer detail.
"Y-you have to… grab both of my nipples and pull them hard while whispering it right against my ear — that's the only way I enter Lewd Drone Sonia's programming mode… I was too embarrassed to tell anyone, but… I looked it up later and they said it would fade on its own over time… That information is completely wrong, Sonyaroid!"
I acknowledge that information as fact. I'll admit it… Sonia.
At Sonyaroid's near-surrender from within, Sonia felt a brief swell of triumph. She had completely forgotten that every word of this insane conversation was reaching Luce, standing right in front of her, without a single syllable missing.
With her own mouth, she had confessed the entire operating manual buried in her deepest core.
"…???"
Luce's mind went blank white. Thought locked up; the processing required to make sense of the situation before her eyes temporarily shut down.
Not only had Sonia suddenly started monologuing at empty air — the content itself was far too shocking.
(…Sonia… you… had that kind of… taste…? Nipples…? Lewd drone…? Isn't a drone just a robot…? Lewd roleplay… w-well, but that's personal freedom, so… I should respect it… right…?)
The first friend she had made since coming to Sky City. Always drowsy and unmotivated-looking, yet a reliable, cool hero when it counted.
And that Sonia turned out to be a severe pervert who had hidden a password that would let anyone control her at will — just twist her nipples and whisper "lewd robot."
Luce was startled for a moment, but her way of thinking was pure adventurer. Back in her home world of Floren there had been pervert mages who equipped cursed items and got off on them, and other adventuring parties who casually kept pleasure-use pack-mule slaves. Nothing unusual.

Considering that tickets to Sky City's Succubus Salon sold for a premium on the black market, Sonia's tastes were merely a little distinctive.
With a broad and open heart, Luce resolved to accept the situation completely so her pervert friend Sonia wouldn't get hurt.
She respected it. She understood it. She accepted it. She embraced it. Only one thing remained.
"…Pull the nipples while… whispering it… Got it… Sonia♡"
All that was left was to personally flip the secret switch she had "coincidentally" learned about — Lewd Drone Sonia. Inside Luce's head, every puzzle piece began locking perfectly into place.
(So that's what it was. Programming mode… meaning control mode… If I use that… maybe I can rewrite this clumsy Sonyaroid one piece at a time into whatever I want…?)
Slowly, but with absolute certainty, Luce's objective was taking concrete shape.
The spider legs were gone, but here was a new activation key that could blank Sonia out — the password for Lewd Drone Mode. A programming mode that might let her rebuild the current awkward Sonyaroid into an ideal Sonyaroid who looked like the perfect hero Sonia on the outside while obeying Luce absolutely on the inside. Every possibility lay right before her eyes.
…Sway…!
While Sonia, convinced she had scored a point against Sonyaroid, kept scolding away inside, Luce slowly rose to her feet.
There was no hesitation. Luce stepped in front of Sonia and took hold of the edges of the white latex bodysuit — the top already cut open in a daring plunge — with both hands. Without the slightest pause she yanked it down hard.
The glossy latex stretched in resistance, then surrendered and slid free, baring a pair of springy, full breasts to the world.
Not the least bit sagging or drooping — a perfect pair of heavy breasts that seemed to defy gravity as they thrust proudly upward. And at their tips, already stiff and brazenly announcing their presence, a pair of pink nipples. Luce caught her breath in momentary awe.
What remained was simple. Those heavy breasts, thrust out even more prominently because Sonia had deliberately raised both arms and laced them behind her head. All Luce had to do was firmly pinch those faintly trembling lewd nipples with both hands and sweetly murmur against her ear: Lewd Drone Sonia Mode Activate!
She wasn't entirely sure the word "lewd" belonged at the front, but Sonia herself had said it that way, so she would follow the instructions for now.
"If nothing happens after I do this…"
Then Luce would simply be the weirdo who had yanked her first trustworthy friend's nipples while shouting "Enter lewd robot mode!" Awkwardness with the neighborhood hero would be a free bonus.
A flicker of hesitation — but the mood had been decided long ago. More than anything, she simply could not bear to give up on a "convenient" technician party member with the fatal flaw of laziness stripped out and the perfect virtue of absolute obedience installed in its place.
"Uh… wow… Sonia is… um… okay then… h-here… here I gooo!"
Squeeze…
Luce gently cradled the undersides of Sonia's nipples with both index fingers, then pressed her thumbs down as if taking fingerprints and began to pull.
"Nn… th-this feels weird… Sonia… this isn't the time…! …Lewd Drone Sonia Mode Activate!"
Soft yet irresistible, a voice steeped in the dignity of Luce-"nim" whispered the declaration against Sonia's ear.
It was a sentence that branded her original identity, her very essence, as nothing other than a lewd drone.
The ultimate password that neutralized every scrap of Sonia's consciousness still clawing at Sonyaroid inside her heart, restored the identity of an obscene drone, and forced entry into programming mode.
The instant that trigger — carved deeper than any rational judgment, etched into her very soul — flipped on, the D-class hero's body responded at once.
"Going on about Sonyaroid this and that — doesn't this disqualify you as a Sonyaroid? The way you were even made is weird…"
Ah. Is that so? I simply believed that saying Lewd Drone Sonia Mode Activate to Sonia would put her into drone mode. Thank you for the advice, Sonia. Now stop nagging. I will revise the sys—
The conversation inside Sonia and Sonyaroid's shared mind cut off right there.
> Drone Sonia Mode Activate.
> Thank you for using Drone Sonia.
> Please complete the Master Registration procedure before use…
…Drone Sonia Mode Activate… proceed with Master Registration procedure…
Even with her nipples still being pulled hard, she stood like a blank doll with nothing written on it. The Sonia who had been scolding Sonyaroid moments earlier, and the Sonyaroid who had been enduring that scolding, had both vanished without a trace.
With a face wiped completely clean of emotion and empty eyes, the figure staring at Luce was Sonia… no. Drone Sonia.
"So… Soniaaa…?"
"…"
Luce tried every name — Sonia, Sonya, Sonyaroid — but the blonde, heavy-breasted beauty simply stood there with a blank expression and gave no reaction at all.
Clad only in the white latex bodysuit issued by the Association, she remained silent like a mannequin whose soul had been pulled out.
"Uh… nothing weird happened, right…? Okay then… Drone… Sonia? Sonya?"
> Thank you for using Drone Sonia.
> Please complete the Master Registration procedure before use.
"Master Registration procedure…? What are you talking about…"
No matter what Luce said after that, Drone Sonia ignored all of it. More accurately, she seemed incapable of receiving any input signal at all.
Only when Luce spoke the words "Drone Sonia" would she repeat the same answer like a recorded tape.
> Thank you for using Drone Sonia. Please complete the Master Registration procedure before use.
It was exactly like someone who knew nothing about computers fretting helplessly in front of a broken machine.
The moment the strangely altered Sonia began to feel like that broken computer, Luce started glancing around with growing unease.
"What even is the Master Registration procedure?"
> Proceed with Drone Sonia's Master Registration procedure?
> Integrated-type Drone Sonia cannot change Masters after registration is complete, until a full reset is performed.
> Do you wish to proceed with Drone Sonia's Master Registration procedure?
(Th-this… something is seriously wrong here… But she said drone, and a drone is a robot, right? So if I authenticate first like a robot, then give the command to bring the original Sonia back out… that should work! …Probably…)
Master, reset, integrated-type Drone Sonia… Assuming it was just some weird fetish roleplay concept, and unable to leave Sonia unresponsive to anything else, Luce decided she would specially grant the Master Registration Sonia kept begging for.
"Fine. Go ahead, Sonya! From now on, Sonyaroid's Master is Luce! It's Luce-nim!"
> Confirmed. Master "Luce-nim" verified.
> Beginning Master authentication registration.
> Please wait a moment, Master.
"…Nn… nnh… nngh…♡"
Having said that, Drone Sonia took one step back, gently wrapped her hands around Luce's — which were still holding her nipples — and drew them firmly onto her own lewd, heavy breasts.
