The Cursed Gender Swap: My Fiancées Are All Men?! The Assassin Noble Luge's Hellish Rom-Com
Rugh Touahade has a problem. Several, actually.
First: he's the heir to an assassin noble house, secretly handling the kingdom's dirty work while maintaining a polite public face. Second: he's been reincarnated from a past life as an organization's assassin, which honestly explains more about his personality than he'd like to admit. Third: as of this morning, every woman in his domain has turned into a man—including Dia, his childhood friend and magic teacher, who is currently sobbing on the fl
The Cursed Gender Swap: My Fiancées Are All Men?! The Assassin Noble Luge's Hellish Rom-Com - The Morning I Woke Up to Find My Master Had Turned Into a Man
"...Hey. You're kidding, right?"
Rugh Touahade couldn't believe his own eyes.
The early morning light spilled through the corridor of the Touahade estate, stretching long and thin across the stone walls. And there, standing dead center in that band of sunlight, was a figure.
Long silver hair. Violet eyes. No mistaking it—this was Dia Vicone, the girl he'd grown up alongside since they were children.
But something was wrong.
She—he—stood close to five foot nine. Broad shoulders, flat chest, and a prominent Adam's apple bobbing at the throat. The jawline was sharper than he remembered, unmistakably masculine. And worst of all, the dress she always wore was clearly a size too small—straining at the shoulders, hem barely reaching mid-thigh.
"Rugh... I—when I woke up this morning, my chest... my chest is flat."
The voice was Dia's. That slightly high, gentle voice.
But it was coming out of a man's body.
For a moment, Rugh felt his past-life memories flicker behind his eyes. The world called Earth, where he'd lived as an organization's assassin. No matter how unreasonable the job, no matter how bizarre the situation—first assess, then act. That was the assassin's iron rule.
But this...
"...Let's just calm down for a second. Come on, Dia. Deep breaths."
"I can't! This isn't fair! I was a proper girl until yesterday! I got in the bath and something felt off, and then I looked in the mirror and—waaaah!"
Dia crumpled to the floor, covering her face with both hands and sobbing. In a man's body.
Rugh wanted to bury his head in his hands.
(What... is going on here?)
He sorted through the facts.
First—his own body was fine. He'd checked the moment he woke up. Black hair, short-cropped. Deep brown eyes. Five foot eight. The assassin's crest of the Touahade family on the back of his right hand. A small silver piercing in his left ear. Same as always—the body of an eighteen-year-old man.
But Dia was different.
She had unmistakably become a man.
"Hey, Dia. For now, let's just... change your clothes, yeah? That dress is really not working."
"But these are the only clothes I have! I tried to put on a skirt, but it wouldn't fit around my hips..."
"...You tried to put on a skirt."
"Of course I did! I'm a girl! What's wrong with a girl wearing a skirt?!"
"No, nothing's wrong with it, it's just—with that body, it's, uh... problematic in several ways."
Rugh chose his words with desperate care.
Even in a man's body, Dia was still completely Dia on the inside. She hadn't shed her feminine sensibilities. Then again, how could she? She'd been a girl for twenty-one years straight until yesterday.
"...Rugh. What am I supposed to do?"
Dia lifted her face. Her violet eyes were swimming with tears, ready to spill over at any moment. That expression hadn't changed at all. It was the same face she'd made as a little girl, crying after botching a magic practice session.
Something in Rugh's chest gave a small, sharp ache.
(I want to protect her. Someone I've always thought of like an older sister is in trouble.)
But that "older sister" currently had a man's body.
"...It's okay. I'll figure something out. I'll fix this."
Rugh crouched down to meet her eyes.
"Really?"
"Yeah. So first, let's calm down. Okay?"
Dia nodded, small and hesitant. In a man's body.
That was when a scream echoed from down the corridor.
"Lord Rugh! It's terrible! All over the estate—people are... people are swapping!"
Rugh stood.
"...What do you mean, swapping?"
"The village innkeeper's wife turned into a man, the blacksmith's master turned into a woman—it's chaos everywhere!"
Rugh looked at Dia. Dia looked back at him.
"...So it's not just Dia."
"What is happening..."
Rugh's mind raced.
(A gender swap affecting the entire domain. I've never heard of anything like this.)
The Touahade family ruled the Vermina Barony of the Alvan Kingdom—assassins, though that wasn't the public face. On the surface, they were peaceful lords. Beneath it, they took on the kingdom's "shadow work." Rugh had spent eighteen years training in every discipline as the heir apparent.
Magic, martial arts, assassination techniques. Combined with the knowledge and experience of his past life as an assassin, there were few in this country who could match him.
But this—
Gender reversal. He'd never heard of such magic.
"First things first—we contain the chaos in the domain. Dia, I'm going to go check on things outside."
"I'm coming too! Don't leave me alone!"
Dia clung to Rugh's arm. In a man's body.
Rugh noticed that her hand was much larger than he remembered—bony, with a man's grip.
(Damn... what is this?)
His heart made a strange sound.
Outside the estate, the Vermina Barony was in pandemonium.
"Hey, my voice sounds all wrong!"
"Weren't you a woman until yesterday?!"
"I don't know! I woke up like this!"
Villagers were panicking everywhere. Men had become women, women had become men. It seemed like everyone—young and old, male and female—had been caught up in the swap.
As the lord's son, Rugh gave calm instructions.
"Everyone, settle down! First, confirm you're unharmed. Then your families. After that, gather in the village square. We'll sort out the situation."
At the sound of Rugh's voice, the villagers regained a measure of composure.
"Lord Rugh! Are you all right?"
"Yeah, I'm fine."
"But my wife... my wife turned into a man..."
"Understood. Just gather in the square for now. We'll talk after."
Rugh guided the villagers while a corner of his mind churned.
(This isn't an individual problem. This is an abnormal situation affecting the entire domain.)
(Who did this, and why?)
(And why am I unaffected?)
The questions wouldn't stop.
But right now, the safety of his people came first.
Rugh led Dia toward the village square. She trailed behind him nervously, tugging at the hem of her skirt. In a man's body.
"...Dia, your walk is a little weird."
"It's because there's a draft between my legs. It's a skirt, but something feels off."
"...I mean, that's, uh..."
Rugh had no idea what to say.
A man's body, wearing a skirt. A draft between the legs. Well—of course. Men had... things down there.
"Look, I'll get you some trousers later. Bear with it until then."
"...Okay."
Dia nodded, crestfallen.
The sight was strangely endearing—and yet, no matter how you looked at it, a man.
Rugh could feel something inside him slowly going off-kilter.
By mid-morning, the chaos in the domain had finally settled.
Rugh sat in the reception room, listening to the village representatives. Dia sat beside him—in a man's body, wearing borrowed men's clothes.
"Lord Rugh, what in the world is this..."
"I don't know. But I will find the cause. Until then, everyone stay home. Avoid unnecessary trips outside."
"But the fields—"
"The crops won't wither if you rest for one day. What scares me more is accidents caused by panic. Please."
The villagers reluctantly agreed and filed out.
Rugh exhaled deeply.
"...I'm exhausted."
Dia slumped against the sofa. In a man's body.
"Same. But nothing's been solved yet."
"I know. A phenomenon like this isn't in any magical records. The stargazer's compass isn't reacting to anything either..."
Dia pulled the stargazer's compass from her chest. A special compass used by stargazer mages to read the arrangement of the stars. Dia carried it with her always.
"I've been checking since morning—no anomalies in the star positions. No magical disturbances either. It's as if nothing ever happened."
"...Meaning it's beyond the scope of magic?"
"That's the only explanation. It's frustrating—my skills aren't measuring up."
Dia bit her lip. In a man's body.
Rugh studied her profile.
The silver hair was beautiful even on a man. The violet eyes still held that same intelligent, gentle light. But the jawline was unmistakably masculine.
(Dia is my magic teacher. Three years older, my childhood friend, like an older sister.)
(And now she's a man.)
(...Damn. What do I do?)
When it came to matters of the heart, Rugh was hopelessly clumsy. It wasn't that he was oblivious to others' feelings—if anything, he was the type to overthink until he spun in circles.
He'd always treasured Dia. That much was certain.
But whether that "treasure" was romantic or familial—even Rugh couldn't say for sure.
"Rugh, look. This."
Dia pointed at the reception room table.
A single letter lay there.
"That wasn't there a moment ago."
Rugh picked it up. No wax seal, no addressee. Just a single line on the back:
"Sender: The Goddess."
Rugh's eyebrow twitched.
(The Goddess...)
He remembered the goddess he'd met when he died in his past life. The one who'd reincarnated him into this world to assassinate the hero prophesied to destroy it.
An entity who shrugged off every intervention in the world as "just a coincidence"—impossible to pin down.
Rugh opened the letter.
Inside was a single sheet of paper. It read:
"This was just a coincidence. If you wish to return to normal, confess your true love."
Rugh stared at the words for a long moment.
"...What does it say?"
Dia peered over his shoulder. In a man's body.
"...I'll read it aloud."
Rugh recited the letter's contents.
"'This was just a coincidence. If you wish to return to normal, confess your true love.'"
"...Huh?"
Dia blinked, blank-faced. In a man's body.
"Confess your true love...? What does that mean? Who's confessing to whom?"
"It doesn't say. But the sender is the Goddess. It has to be the one who reincarnated me into this world."
"The goddess who reincarnated you... the one who asked you to assassinate the hero?"
"Yeah."
Dia knew about Rugh's past life and about the Goddess. Rugh had confided his secrets to Dia and Dia alone.
"...The Goddess doing something like this. I still can't figure out what that woman is thinking."
"'Just a coincidence,' huh. Same flippant nonsense as always."
Rugh crushed the letter in his fist.
(Confess true love. So to break this curse, someone has to confess to me?)
(No, wait. Confess to me? Why me?)
(And would a confession actually break the curse? Not me confessing to someone else?)
The questions kept coming.
But one thing was certain.
"...Dia. I'm going to the royal capital, Alvein. I'll investigate this curse at the Royal Academy of Magic, Arcadia."
"The capital? But what about the chaos in the domain?"
"I'll leave it to my father and mother. They should be at the estate now. Besides, the people have calmed down somewhat. What we need now is information. The Royal Academy of Magic holds the greatest concentration of magical knowledge in the country. As a research institution for stargazer magic, it's the finest on the continent."
"...You're right. I have things I want to look up in the academy's library too. Whether there are any records of gender-disruption magic."
"Gender-disruption magic?"
"Yes. It exists in theory—a high-level spell to swap genders. But there's never been a single recorded success in history. This curse might be connected."
Dia's voice had regained some of its usual energy. When it came to magic, Dia became absorbed. That much hadn't changed, even in a man's body.
"...Dia. Will you come with me?"
Rugh hesitated before asking.
Dia looked surprised for just a moment—then smiled softly. In a man's body.
"Of course. I'm your teacher, aren't I? I can't just abandon my student when he's in trouble."
"...That helps."
"Besides, this is my problem too. I want my body back as soon as possible. These shoulders are killing me."
Dia tapped her shoulder. In a man's body.
Rugh couldn't help but laugh.
"...What are you laughing at?"
"Nothing. Let's get ready. It's a day by carriage to the capital. I want to leave before sundown."
"Got it. But give me a little time first."
"What for?"
"...The washroom. And a change of clothes. This shirt is tight around the chest."
Dia fidgeted with the col
