Mom, I Became a Female
"Sorry. I don't have anything else to eat. Want some coffee instead?"
"No! I'm fine!"
"Hmm."
Horns sprouting from her head.
A tail standing stiffly upright.
Small wings attached to her back.
Is she a demon?
Since her unique trait was Incarnation of Lust, she figured it probably wasn't the benevolent variety.
Still, she never expected an actual demon to show up right away.
Had the system sent her some kind of summon?
Her starting stats were pretty pathetic for an awakened hunter, after all.
Of course, that was only Runa's assumption.
The demon in question—Arma—was currently racking her brain in desperation.
Shit... did I get this wrong?
At first she'd been certain the person in front of her was one of her own kind.
There was no way a woman who'd only been female for a single day could act with that kind of attitude and confidence otherwise.
But Runa was unmistakably human.
She just had terrifyingly fast adaptability.
"Why? Do you need cum or something? I don't make it anymore, though. When my friend gets here later..."
"N-no, that's not it...!"
"Aren't you a demon? You should've taken the offer when I made it."
"In any case, our contract routes a percentage of the vitality you obtain to me as well..."
"Vitality?"
"Ah, the system registers it as points."
"I see."
The fact that she didn't understand contracts or the system made it obvious.
It was obvious, and yet.
"Just talk casually. You said calling me senior earlier was a misunderstanding, right?"
"I'll... I'll ease into that gradually...!"
It was as if every demonic instinct in her body was screaming at her.
That if she got too cheeky with this woman, something truly terrible would happen.
At the very least, the version of herself that had grown pathetically weak over five thousand years was in no position to challenge her.
The raw feminine power radiating from Runa right now was easily a level above her own.
What the hell... what the actual hell is this...?!
Every target Arma had pursued until now had been the so-called alpha males—proud, arrogant types who treated women like objects.
That was exactly why she'd gone berserk when she herself became female; she couldn't accept it.
But Runa was different.
If anything, she was the complete opposite.
"You really won't have any? The coffee at our place is pretty good."
"It's not that I dislike it, but..."
"Then drink it. I'm good at making coffee. Even if the machine does most of the work."
"Y-yes, ma'am."
Thanks to the handsome features he'd possessed since childhood, he'd always gotten along with girls far more than boys his own age.
On top of that, he had two older sisters and had lost his father early, so his environment had been nothing but women.
That was why becoming a woman himself hadn't thrown him into too much confusion.
All he had to do was copy the behavior he'd watched the women around him display his entire life.
Of course, only Runa herself knew exactly what kind of women those had been.
"Well, anyway, you came all the way to Earth because you had nowhere else to go? I wasn't thinking much of it, but hearing the whole story makes it kind of sad..."
"Yes, that's about the size of it."
"I've become a hunter now too, so I'm planning to give it my best shot. I'd like to be helpful if I can."
"...Thank you."
But that was as far as it went.
She might not prefer sexual methods, but there were still plenty of ways for a demon to threaten and torment humans.
Even while acting cooperative like this, the moment a tiny opening appeared, she would exploit it without hesitation.
Things humans could never let go of, for instance—like their friends or family.
Ring, ring, ring.
"It's Mom."
"...! Q-quickly, answer it!"
Right on cue, Runa's phone began to ring.
Arma told her to pick up, but her inner thoughts were something else entirely.
Hehe. How is she going to answer that? No matter how much of a natural-born female you are, telling your family is on a completely different level, isn't it?
Runa would surely be unable to take the call.
And then she would realize.
Exactly what kind of situation she was in.
Click!
"Hah... hah..."
"You made it?"
At the same time, Sanho burst through the door.
Fearing Runa might have caused another incident, he'd run the whole way, his forehead drenched in sweat.
"Hey, you didn't do anything stupid, did you?"
"I was just sitting here drinking coffee. Ah, it wasn't an accident I caused... Huh? She's gone."
"What is it? What did you do this time?"
Arma had already hidden herself inside the shadows.
She wanted to observe the situation.
That male friend of hers could be a variable, but she figured the outcome wouldn't change much either way.
Ring, ring—.
"...Is that your phone?"
"Yeah. Mom's calling."
"What? The auntie?"
How will that relaxed face change?
Will she start crying?
Maybe she'd throw the phone in fear.
Or perhaps begging her friend for help would make for quite the entertaining sight.
Arma began to form a wicked smile as she imagined it.
It might be fun to start with the friend instead of Runa.
But.
Click.
"Yeah, Mom."
"Huh? Why is Munyoung answering? I definitely called Munseong."
"This is Munseong. So, um..."
"...! Hey, hey, wait...!"
There was one fact she had overlooked.
"Mom, I became a female."
That Runa's family was far more open-minded than anyone could imagine.
"Hmm, so that's what happened."
"I should have told you first, but I'm sorry."
In the end, Sanho—utterly horrified by Runa's unfiltered declaration—snatched the phone away and continued the call himself.
Surprisingly, her mother seemed to accept the situation rather easily.
With gates appearing in the world, becoming a woman wasn't such a big deal, she said.
"It's fine~ You must have been confused too. Where would you find the time to explain? So, Munseong—no, what did you say your name was now?"
"Runa. I'm going with Lee Runa, Mom."
"Runa? Your sisters are Lee Munyoung and Lee Mungyeong, though?"
"But this one sounds like a foreign name and it's cool, right? When I start making a name for myself as a hunter later, it needs to be easy to say."
"That makes sense... Anyway, got it. Mom's out shopping, so I'll hang up now, okay?"
"Yeah. I'll call again tonight."
"Okay~ Listen to Sanho while he's helping you. Love you, my daughter?"
"Love you too."
Watching Runa make loud kissing noises at the screen, Sanho sank back into his seat once more and began blankly reevaluating his entire sense of common sense.
The one who received the biggest shock, however, was Arma, who had been hiding nearby.
She was so stunned that her concealment magic automatically dispelled.
"W-what the hell is this?! Runa! Just what are you...!"
"Huh? Hey, w-wait. What the... what is that thing?"
"My contracted demon."
"What?!"
"My trait is Incarnation of Lust. Just think of her as a summon the system sent over."
"...What's her ability?"
"Um... making semen taste sweet?"
"I-I don't have an ability like that?!"
"A succubus can't even do that? I'm disappointed."
By this point, Sanho had given up on thinking entirely.
A friend who had suddenly become a woman.
An attitude that had transformed completely the moment she became female.
A family that accepted it all without batting an eye.
And now a demon on top of everything.
Honestly, the demon was the least shocking part at this stage.
That could happen, sure.
"Can you fight at all, then?"
"I-I can, but... honestly, I think I'm weaker than Lady Runa right now..."
"Useless, then. You're demoted to my contracted onahole."
"That's too cruel!"
"......"
A demon hearing the word onahole from a human... well.
That could happen too, apparently.
All Sanho wanted now was to go home and sleep for about three days straight.
"...Put this on first. We're heading to the association."
"Thanks. Wanna watch me change?"
"Uh, no thanks... I'll come back in five minutes, so make sure you're fully dressed by then."
Thud.
Watching Sanho close the bedroom door with slumped shoulders, Runa let a small smile slip across her face.
Adding one last teasing remark was simply mandatory.
"You've never seen a real woman's naked body before, right~? I'll show you."
"Get lost!!"
"...You really do remind me of senior somehow."
"Huh?"
"Ah, never mind."
For some reason drained of energy, Arma slipped back into Runa's shadow.
Left alone at last, Runa.
With no one left to tease, it was finally time to actually change clothes.
She wondered what kind of outfit that insensitive guy had bought.
"Hmm. Classic, I guess."
A white t-shirt and jeans.
She remembered Sanho saying something similar once while drunk, staring at a standing advertisement on their way home.
He liked modest women who looked good in simple clothes like these.
What had she answered back then?
To look good in clothes like that, you'd need to be an SSS-rank alpha female, not some A-rank, you high-standard virgin bastard... She had thought it but hadn't actually said it, as far as she remembered.
And now here she was in reality.
The woman who actually looked good in these clothes.
It wasn't bad.
If only this virgin hadn't made that tiny little mistake.
"I'm dressed. Let's go."
"...You really put them on, right? If you pull any more shit, I will actually hit you. I might not be able to hit a woman, but I think I can hit a woman who used to be a man."
"A hunter assaulting someone is a serious crime... Oh, right. I'm a hunter now too."
"Sigh..."
With that pointless exchange, Sanho opened the door and stepped into the living room.
Fortunately, the sight that greeted him was Runa properly wearing the clothes he'd prepared.
But there was one thing that kept catching his eye.
On top of an upper body that already demanded attention, something small kept making direct eye contact with him.
"Hey, you crazy..."
"Hmm? What?"
"Aren't you going to wear your clothes properly? Have you lost your mind?!"
"But the person who bought them didn't get me a bra. I need something to wear if I'm going to wear anything."
"...Huh?"
"And look at this. You somehow managed to guess the bottom size by eye, but you didn't account for the chest at all, so it's turned into a crop top."
"No, that's... I mean..."
Sanho tried to come up with an excuse.
But with her breasts thrust right in front of his face, his reason kept short-circuiting.
Of course, Runa had approached precisely because she knew it would have that effect.
"Hmm, what should I do? If I go out like this, people will stare. They'll definitely think we're doing some kind of exposure play... What now?"
"No, ha. Stop exaggerating. Please, just give me a second. Let me think."
"Uhhuh. If it's that bad, should I help you out?"
"...What?"
There was actually a very simple solution.
She could just throw on any of the overflowing clothes Lee Munsung still had in the closet.
But Runa had absolutely no intention of offering that solution.
Because watching his flustered face was far too entertaining.
"Just wait a second~"
"......"
She gracefully rummaged through the drawer beside the table and soon pulled something out.
It was.
"Sanho, put this on my nipples for me."
A small band-aid.
