The Bath of the Silver Moon
We now find ourselves facing an unprecedented crisis.
The surface has been contaminated by radiation, and every living thing is dying or mutating.
An underground factory, severed from the outside world. Resources dwindling by the day.
An artificial city planned by the Administrator AI — the Great Cavern.
The kind of bleak, hopeless city you'd only ever see in post-apocalyptic fiction.
If we can complete this, will we be able to endure — to remain human?

The record of Kim Hyun-tae, factory laborer
"Your hair."
Shaaaah—
The water I poured streamed down the knight's beautiful silver hair.
"I'll lather it up now."
"Good."
And so I worked the soap into a lather and washed the knight's hair.
Bubble, bubble.
"Haaah…"
The knight let out a sound of pure contentment.
Today was my first time attending her bath.
Please, let her find nothing to complain about.
Liana von Eisenhardt.
That is the name of the knight I serve.
Sharp-tongued as she may be, she is a truly extraordinary person.
A knight bearing an epithet, no less.
Liana, the Knight of the Silver Moon.
An epithet reserved only for genuine knights — one earned by felling over a hundred orcs.
Yet for all her renown, I am the sole attendant in her service.
"I'll rinse it out now."
"Good."
Shaaaah.
She sat so still, so perfectly composed, that she looked like a doll.
In truth, even her profile from behind had that doll-like quality.
Silver hair with a beautiful, lustrous sheen.
Snow-white, flawless skin.
Shoulders slightly broad for a woman, yet with such a delicate frame that she seemed almost frail — though the muscle along them was faintly developed, squared and firm.
A slender, toned back.
And between her back and underarm, a shy glimpse of the side of her breast.
A pinched waistline that drew a perfect capital S.
And below it, a hip line that boasted a downright violent width.
It was the body of a beautiful female knight, as though sculpted by the hand of God himself.
"Your back."
"Yes, I'll wash your back now."
Of course, minus the way she spoke in those clipped little commands.
The knight favored short, brusque speech like this.
Which meant my mood soured a little at a time. That was a bonus.
Shaaaah.
I splashed some water over her, then worked up another lather and rubbed it across the knight's back.
The sensation was smooth and supple, springing against my palm.
"Haaah…"
Again, the knight made that contented sound.
Even if her curt commands chafed at me for a moment, seeing her like this made her seem almost… endearing.
Besides, as far as I knew, I was the first attendant ever to attend the knight's bath.
'I'm the first one to ever lay hands on this beautiful body.'
A pointless little thrill of satisfaction welled up inside me.
Come to think of it, the knight was a bit of an odd one.
For most knights, having an attendant see to their bath was perfectly routine. But she had never once allowed it before.
Then, out of nowhere, today she suddenly ordered me to do it.
'Maybe someone talked her into it?'
That seemed unlikely.
I'd never once heard that the knight had any friends.
Naturally, the servants gossiped too.
With that signature bluntness of hers, she apparently got frozen out even within knight society.
The only remotely plausible candidate would be… Elise, who lived with her?
But Elise was an apprentice knight… not really in a position to give the knight advice directly…
"I'll rinse it out now."
"Good."
Shaaaah.
The foam slid off the knight's back, revealing that firm, toned line once more.
Strength and delicacy.
Two words that should never coexist — yet did, on an impossibly beautiful back.
"This feels nice."
"Thank you."
"I should have ordered this ages ago."
"…So it seems."
What could have changed her mind?
No one lived a more rigidly patterned life than the knight. She wouldn't just change her heart on a whim.
"I'll be calling on you for this regularly from now on."
"Yes. Then I'll take my leave."
I turned to go —
"Ah. Wait a moment."
The knight called out to me.
And then, what my eyes fell upon was —
"Gah."
The knight's bare body, turned around to face me.

The first thing that caught my eye was the knight's chest.
Not exactly enormous or overwhelming, but a plump, springy pair that carried surprising presence — utterly out of keeping with her lean, toned frame.
And a pretty pair of pink nipples.
And beneath them —
'Wait, what is that? That's a womb tattoo!'
I very nearly screamed it out loud.
A womb tattoo.
The mark of a sex slave — etched across her lower belly.
The sight was so shocking that the memory of the knight's springy chest, which I'd laid eyes on mere seconds ago, was blasted clean out of my mind.
A pink tattoo glowing faintly against her white skin.
An intricate pattern of flowers and tangled vines — somehow noble and yet strangely, disturbingly sensual.
For a moment, my mind simply went blank.
'Th-that tattoo…'
I remembered the post where I'd first seen that tattoo.
So I finally bought one yesterday.
High-end model made exclusively for sex slaves. The yass series.
Factory-customized with the full version of the sensory module.
The photos did NOT do it justice. The real thing is insane.
Body's a given, but especially that womb-shaped tattoo on her lower belly — every time I mount her while looking at it, I get horny as hell.
These devs made the tattoo an actual work of art.
To all the bros going "how is a tattoo art?" — explanation below.
The tattoo is an orgasm gauge.
It fills up little by little depending on how much pleasure the android is feeling.
Fill it completely and she climaxes, howling like a beast.
And every time she climaxes, it glows more and more pink.
Each model has a different personality — I bought the tsundere type.
She acts like nothing's happening at first, but trembles a little more each time the gauge fills. And then you check and the tattoo is glowing pink. Legit the hottest thing ever.
Max out the sensory module and even if you're a total dud, the gauge climbs fast and she cums like crazy.
Highest possible recommendation. Money well spent.

A post I'd read once in the Record of the Gods — the Tower of Babel.
And a tattoo of nearly identical design to the one in that post's photo was embedded in the knight's lower belly.
Just then, the knight's voice snapped me back to my senses.
"I-it is nothing. Leave at once."
Her cheeks were faintly flushed — she must have felt my stare.
I hurried out of the bathhouse.
But still — why on earth had she called me over in the first place?
My dark little room, where I returned after finishing the bath service.
A room meant for "servants."
A four-person room, and I was alone in it.
When I first arrived, Eric had been here.
But Eric had left a week ago.
Having him around had at least put my mind somewhat at ease — but apparently, the knight had been too much for him.
"She's a genuinely exhausting, ruthless bitch. Damn her."
That's what Eric said when he left.
He wasn't the type to curse people out by nature, so he must have been through hell.
"When you get out, let's grab a drink. My treat. We can trash-talk that damned woman together."
There was a time that offer tempted me. But after today, the thought was gone.
Because I possess the knowledge of the Tower of Babel.
"A womb tattoo. And a sex slave android."
Reading that post over again, slowly, combing through every line of it, I noticed a word I didn't know.
"Sensory module."
I searched the Tower of Babel again for that key term.
And I read the most thoroughly organized post on the subject.
Androids were built to look as close to humans as possible so as not to unsettle them.
But sex slave androids come with a special piece of hardware.
The sensory module.
From what I hear it hyper-activates the parasympathetic nerves several times over — the technical details are beyond us, whatever.
Most sex slave androids have sensory modules hidden at two points: the center of the lower-belly tattoo, and the center of the solar plexus.
Lower-belly tattoo → Sensory Amplification Module
Activated by touching it in a clockwise, circular motion.
Each input doubles the sensitivity.
Keep stimulating it and sensitivity climbs to dozens of times normal.
Yes, that means "sensitivity ×XXX!" from eroge is actually achievable.
Solar plexus → Sensory Suppression Module
If she gets so sensitive she just keeps going over the edge nonstop, you regulate things here.
Combine the two well, and
you can stage the full arc — nothing at all at first, then utterly broken by the end.
Adjust to your preferred sensitivity and enjoy a happy sex life.
※ FYI, the kissen models apparently have the amplification module in the anus. Those are absurdly expensive ultra-luxury models, so I'll pass.
Androids, huh.
In the age of the gods, it was a word for machines built in the gods' own image — that much was certain.
Miraculous creations: modeled as faithfully as possible upon the form of the gods so as not to unsettle them, yet given far hardier bodies so they could be sent into harm's way in their place.
"If the knight really is an android, then everything is explained."
She would be an artifact forged by the gods themselves — it only stood to reason that no human could hope to match her strength.
Our own Great Cavern was likewise a legacy of the gods, stuffed full of things humanity still couldn't properly comprehend.
Which meant that debating the authenticity of that post would be a foolish exercise.
It was a record of the gods, after all.
It wasn't as if this were the first or second time I'd reaped the benefits of the Tower of Babel's information.
For instance — when I followed the teachings of some great god's record, The Essential Mana Cultivation Technique When Dropped into an Isekai… I actually gained mana.
For the record, mana is knowledge even the knights don't possess.
That's why I have such abnormal stamina for a mere servant.
The problem is that the knight's tattoo might just be an ordinary tattoo that happens to share the design.
I couldn't rule out the possibility that she'd simply gotten some lewd body art as a hobby.
Which meant I had to verify it. Tomorrow.
"But something's off here…"
Wasn't the knight somebody's daughter?
A daughter born of humans in this present age, that is.
So how could she possibly be an android from the age of myth?
"Eh. There's probably something I don't know about it."
I decided to set that question aside for now.
And with that, I pulled on my sleep mask and brought an eventful day to a close.
