Testing Our Compatibility
The sight unfolding before my eyes was, in a word, phenomenal.
It was a space that was hard to believe existed beneath the earth.
Like a secret city hidden within the ruins, a bizarrely glamorous and sophisticated atmosphere spread out before me. It wasn't exactly a skyline glowing like Seoul's Gangnam, but it certainly wasn't some backwater village, either.
The buildings were small, but the commercial streets were laid out in an orderly fashion. With a bustling market where people came and went, and even streetlights, the scenery didn't fit the word 'monster' at all.
Most of all.
“...The sky?”
“It’s... the sky...”
“No. Look closely. It’s a virtual display composed entirely of LED panels.”
The moment I looked up, a blue sky with clouds drifting in real-time floated above my head. A fake sky, hovering in an underground space without a single breeze. It was so elaborately designed that it felt like someone's camouflaged heaven.
It was a display so precise it gave the illusion that the air was as blue and gently flowing as it was on the surface.
...This is insane.
Seriously, they said this was a village where monsters lived, but this is basically an underground resort, isn't it?
That was when it happened.
“Everyone~ I’m back!”
With an excited voice, Lyla strode into the village. Then, a moment later.
“Oh, it’s Lyla!”
“Lyla’s back!”
“We were worried about you, kiddo!”
Suddenly, signs of life began to increase from deep within the village. From the gaps between buildings, behind billboards, and through the cracks of quietly closed shop shutters, androids began to reveal themselves one by one.
All of them were infected. Pink eyes, faint tentacle marks tracing their skin. They looked alien and dangerous. But their behavior was different. They didn't draw weapons, and they didn't pounce. They just watched us cautiously.
Then, someone asked in a small voice.
“...Who is that with Lyla?”
Soon, dozens of pairs of eyes were fixed on us at once.
“...Are you, by any chance, the ones who saved Lyla?”
“Huh? Ah, well... I suppose so?”
“Thank you. Thank you so much... Lyla is the youngest infected in our village, so we were always very worried.”
“Thanks to you, she was able to return safely. You are... our benefactors.”
What happened next was, I dare say, a runaway train.
SENSORY OVERLOAD
In an instant, countless androids swarmed me from all sides. Over bodies marked by parasitic traces, there were impossibly voluptuous breasts, soft thighs, and a strange heat radiating from between the tentacle marks.
“Benefactor, you’re so cool...♡”
“Thank you for helping Lyla, really...”
“It’s our first time meeting someone like you in our village.”
Perhaps it was because they were hugging me from both sides, rubbing against me, and pulling at my waist. I’d been on a 'no-fap' streak for over ten days, and my partner inside my pants was already fully prepared.
My face was buried between breasts, *pafu-pafu*-ing away, and my reason was slowly being encroached upon by instinct.
However, at that moment.
“Step back.”
Zing—.
A blade was drawn with a sharp mechanical sound.
“Eek?!”
“A, a combat android?!”
“S-scary...!”
The androids that had been caressing me just a moment ago began to retreat all at once. Over my shoulder, one figure walked toward us with heavy steps.
“Chanwoo-nim... stop acting like an idiot and come over here.”
With a blank face, a gloomy killing intent, and a blade in hand, Revi stood directly in front of me. Even Serika was glaring at me from the side.
“Chanwoo-nim... this time, Revi is right. Seriously.”
Wait, weren't you two a cat and dog that were always growling at each other? You were always just doing WWE, so why are you trying to do UFC on me now...?
I read the room and quietly moved toward the two of them. The moment I did, arms wrapped around me from both sides without a word. The left side pressed in softly, and the right side pressed in heavily.
How should I put this? It felt like I was being wrapped in compression bandages from both sides, with the only difference being that those bandages were all voluptuous breasts. Thanks to that, my little friend down below reacted harder and faster than the heart in my chest.
"This is my spot!"
"Chanwoo-nim must stay by my side."
Like a silent threat, the two androids held me tight, their heavy breasts wrapping around my arms as if declaring silent ownership.
After the atmosphere shifted, Serika looked up again and said.
“Everyone here is infected, meaning you are monsters.”
“...!”
“B, but we’ve just been hiding here...!”
“We’ve never attacked an android!”
Serika looked at them with sharp eyes.
“Even so, androids pull the trigger based solely on the ‘potential for danger’ to humanity.”
For a moment, a tense atmosphere flowed among the infected. No one could open their mouths, and only an uneasy silence hung in the air. Then, Serika spoke again.
“I want to meet your leader.”
“Th, the leader...? Surely... you don't mean Placia-nim...?”
“You want us to introduce Placia-nim to people like this...? No way...”
Whispering voices. Confusion spread across the faces of the surrounding infected. It was as if they were facing an unexpected crisis, and they began to look at each other.
And that was when it happened.
“Don’t go scaring the kids, you idiots!!!”
A deep shout that shook the entire tunnel. The voice, which burst out like an echo, made even the air tremble, overturning the atmosphere in an instant. At the same time, the arrows on the electronic display moved in unison. The red directional indicators flickering on every screen pointed precisely to one spot.
“If you want to meet me, just come. I was dying to see your faces anyway.”
A strange, raw voice. But a presence that dominated the space at once. We were speechless, and we slowly turned our heads to follow the path the arrows pointed to.
Placia. The one who breathed life into this city. Despite being a monster, she was the mysterious designer who built technology and order. And now, that existence was calling for us.
...Soon, the real meeting would begin. Not just a simple encounter, but the first step toward approaching the essence of this bizarre world.
The place we arrived at, following the arrows on the display, was deeper underground in the tunnel village. It was a space that still bore the traces of being used as a sewer in the past. The sweltering heat and the unrefined, humid air. In this place, where even your breath felt hot, a mechanical hum was ringing out like a workshop that had just stopped operating.
And what made it more suffocating than the heat was, without a doubt, that woman.
“…Lewd.”
I couldn't help but mutter that in all sincerity. Placia. The technician of the tunnel village that Lyla spoke of, and the source of the anomaly that shouldn't exist in this world. And the reality standing before my eyes now was too sensual to be just an engineer.

Her top was half-peeled off over her work clothes. Her cleavage was exposed, and her swollen curves stood out subtly through the sweat-soaked fabric. The red underwear she wore inside was bold, as if she’d intended to highlight her breasts, and her sweat-drenched red hair flowed down her neckline, adding a strange luster to her skin.
This wasn't workwear; it was a deliberate 'production.' The appearance of a queen who used seduction as a weapon instead of tools.
“So it’s you guys. The first androids and... the living human to ever enter our tunnel village.”
“...!”
“Chanwoo-nim. Please step behind me.”
Serika stepped in front of me in an instant. Revi also summoned her blade to her fingertips and took a threatening stance. But Placia just raised one eyebrow lightly and pointed at the pipes with indifference.
“You’d better stop those hands right there. The equipment here is old. If you touch it wrong, gas might leak, and while we might be fine... a human would definitely end up dripping down like 'lubricant'.”
This woman, her way of speaking is dangerous, too. She seemed ready to melt a person with a single breath, let alone gas.
“H, how dirty, using Chanwoo-nim as a hostage...!”
“Hey, that’s unfair? I never took him hostage.”
She laughed lightly and spread her arms. A relaxed and laid-back attitude, and a single drop of sweat flowing between her breasts. This wasn't a negotiation; it was a game where it had already been proven who was on top.
“...Both of you, put your weapons down for a second. I want to have a conversation with Placia-ssi, too.”
“Chanwoo-nim...!”
The two androids’ expressions stiffened, but I walked quietly toward her. Placia-ssi scanned my body from head to toe, then a playful smile played on her lips. It was a look that seemed to whisper, ‘I like you,’ with just a single glance.
"Nice to meet you. What was the human's name again?"
“It’s Kang Chanwoo.”
I offered a handshake with trembling hands. Of course, there was a softer texture I wanted to hold more than her hand.
Placia placed one hand lightly near my chest, then leaned in close and brushed against my ear. Her soft, warm breath tickled my earlobe. Then, with a playful light in her eyes, she whispered quietly.
“Chanwoo-ssi. Excuse me, but... I have something to tell you in private. It’s a story for just the two of us... would it be okay if I whispered it?”
“Ch, Chanwoo-nim! It’s dangerous!”
“That’s right! Just looking at her, you can tell she’s as devious as her breasts are large!”
Well, to my eyes, it was just voluptuousness overflowing with happiness. In any case, I tilted my head obediently, and her breath seeped into my ear. The sensation was less of a conversation and more of a seduction.
“When you want to get closer to someone... do you believe that the body speaks louder than words?”
“...I believe it.”
“Then... tonight, why don't we see if we’re compatible by 'bumping and grinding' with each other?”
“Yes!”
The master of the tunnel village, Placia. In this moment, I became certain about her. This woman is definitely our 'ally.'
