Vol 1 Chapter 1 – Prologue

That’s the reality of this world of swords and sorcery, beneath the twin suns that rain down starlight.
It’s madness—plain and simple.

From the moment they’re born, men are blessed with status, treated as the chosen few. They’re spared from everyday hardship, granted privilege, and tasked only with one duty— to sire children with the women selected for them.

The women, on the other hand, live very different lives.

Their greatest problem isn’t hunger, war, or poverty.
It’s lust.

In this world, where only one man exists for every ten thousand women, the genetic memory passed down through generations drives women to crave strong males with a hunger they can’t suppress. That instinct, that overwhelming desire, rules them.

Yet even as they’re tormented by that craving, most women never meet a man.
So they throw themselves into work, sweating day after day— not only to support themselves, but also to sustain the idle lives of the men who’ll never need to lift a finger.

You could say this world runs on inequality.

“Fwaaah…”

In this world, I was born a man.

Thanks to that simple fact, life had been… well, easy mode.

At fifteen years old, I’d never faced a single real hardship. The world practically handed me everything I needed on a silver platter. These days, I even ran my own shop—nothing fancy, but enough to live comfortably.

“E–excuse me…”

A timid voice called from the entrance.

“Welcome,” I replied, glancing up.

Standing there was a cute girl, clutching a small ticket I’d printed myself.

“U-um… i-is it true? That you really… have those kinds of things?”

“Hmm?”

“I mean… things that are… lewd?”

Her words were hesitant, but they hit hard.

“Wait, are you saying a man runs a shop like the one from the rumors?”

It wasn’t an unreasonable question.

In this world, almost every man despised women. No—feared them. Women here were infamous for their aggressive desire, their predatory obsession with men. For most males, that was enough to scar them for life.

They saw women as beasts driven by lust, unclean creatures to be avoided.

And truth be told, they weren’t entirely wrong.

Still, I was different.

I remembered living in modern Japan—a world where men and women existed in equal numbers. I’d been a college student there, just another guy. After dying and reincarnating into this world, I’d kept all my memories… and none of this world’s fear.

“Yeah,” I said with a small smile. “You heard right.”

The shop I ran was, by all accounts, an adult establishment. In my previous life, it would’ve required an R18 label—no question about it.

But here, it was something else entirely.

While the men of this world had all but lost their physical drive—shrunken, weakened, lucky to perform even once a month—I was different. My body, my instincts, my stamina… all still very much human. Every day, I felt the same needs I had back on Earth.

Maybe that’s why I called myself a missionary of desire.

And maybe that’s why I’d died a virgin in my past life, just when I was finally considering a trip to an actual brothel.

So when I woke up in this world, armed with privilege and a healthy libido, opening a shop like this felt… inevitable.

“Go ahead,” I told her. “Take a look around. See anything you like.”

“W-wow… these are all really… used, right?”

“Mm-hmm. Every last one.”

On display were my personal belongings—worn clothes, toothbrushes, small items from daily life.

It was, in a way, a kind of trade in intimacy. Since I was the only staff here, I couldn’t entertain too many customers. Selling my personal effects was my way of balancing demand.

“And judging from your clothes… you’re from the common district, right? Not nobility?”

“Y-yes! I mean, no—um, I’m just a regular girl, so I shouldn’t even be here…”

“That ticket in your hand—didn’t I issue that as a prize for the shopping district’s bingo event?”

“Y-yes!”

“Then you have every right to be here. That’s a genuine priority pass. Anyone holding one can visit my shop. So relax, alright?”

As she blushed furiously at the counter, I stood and walked over, closing the distance between us.

“Mind if I take the ticket?”

“Y-yes, of course!”

“What’s your name?”

“R-Reine…”

“Reine. Pretty name.”

“Eek!”
