Subspace would put a device on the reader’s d*ck, and have little buttons for it. If the reader does something bad Subspace will shock them, if the reader dose something he likes he’ll send a wave of pleasure
Subspace questioning a human! Reader about how their spices reproduces. Reader gives a very exasperated explanation that takes like 30 minutes to finish, because they never thought that they would have to explain this to a being that doesn’t have the same genitals.
“And do you have the type of genitals that go into the others, or do you have the one that takes it?”
“Uhhhh, the one that goes in…?”
“Good”
“Hunnn, don’t touch me there. Were different spices we can’t reproduce”
PHIGHTING! x Demon!Y/n (Crossover fanfic : [Roblox] PHIGHTING! x Demon Slayer)
Warning : OOC!Character / Violence / Blood / Gore / Demon!Y/N / Female!Y/N (Sorry, but I comfortable with this) / Major character dead and reincarnated later / Gun / Drug Dealer / Swearing 🤬 / Some character might turn into Yandere later.
Pairing : Various Yandere!Phighting character x Demon!Y/N
Note:
Okay… I know, I know. Yandere!Medkit x Human!Reader isn’t completely finished yet, but it's really, really close! I just have a little more content to adjust and add, and I’m currently studying the PHIGHTING! Wiki to make sure the characters’ personalities are as accurate as possible. The same goes for Houseki no Kuni x PHIGHTING!
I also want to apologize for making the main character female. The simple reason I chose a female reader is because it’s more convenient for me, and it’s what I personally prefer. I’m sorry to readers who would have preferred He/Him or They/Them.
(Although, I do get a little frustrated when some readers complain about the main character’s gender. I think this should simply be a matter of the author’s preference and convenience. I’m the one writing the story, and this is how I want to write it. If you don’t like it, you can simply scroll past it, it’s really not that difficult. I’ve also seen plenty of stories where authors make the main character a gender other than female, especially on AO3. There are tons of them.)
And here are the headcanons before you start reading:
Every Inphernal has Marechi Blood because their physically is stronger than humans.
Demon!Y/N is an ordinary demon with the basic abilities that normal demon possess. However, Y/N will become stronger over time. (Y/N is already quite powerful from the beginning, and strong enough to fight an Inphernal one-on-one. However, if she gets ganged up, she will inevitably lose. But she can't die. Only play dead just to regenerate her body back.)
Demon!Y/N can be killed in four ways: being executed by a Nichirin Sword, being burned by sunlight (although Y/N will overcome this weakness later), wisteria flower poison, and Muzan’s curse.
However, because Demon!Y/N is transported into PHIGHTING! universe, sunlight will be the only way to kill her. Y/N will eventually overcome this weakness later.
Some characters from PHIGHTING! may eventually become Yanderes… but not every character will become a Yandere. (Or maybe they might? Just… at a relatively safe level, I guess?)
At the beginning of the story, the characters will have some communication difficulties because they speak different languages. However, Y/N will eventually learn their language and will definitely be able to communicate with the Inphernals.

Prologue
You were pretty sure you were doing your absolute best to look like a peaceful visitor. Someone who had absolutely no intention of picking a fight with anyone.
Or was it because of your blood-red eyes, their pupils narrowed into thin slits like those of a beast, combined with your long fangs that became impossible to miss whenever you opened your mouth or flashed a wide grin?
Or perhaps it was because you weren't exactly a creature that was supposed to exist on this planet in the first place?
Maybe that's why he just wouldn't stop following you.
The creature was tall and massive, with thick muscles undercover by his clothes, a pretty clear indication that he was probably quite strong. He had no hair, with a pair of horns in its place, one orange and the other light blue.
And then there was that scent.
A scent so intoxicating that it made you want to lunge forward, tear into his flesh, and ravenously drink his blood.
Marechi Blood.
The distance between him and you never exceeded five meters. Not by much, either. That meant the scent of his blood remained unbearably strong and consistent, until you finally couldn't take it anymore. You raised a hand and pinched your nose shut.
It wasn't because you were disgusted.
You were just afraid you might lose control and go berserk.
“@+##-฿&฿-#&#_#&#”
And thanks to the abilities that came with being a Demon, your hearing was pretty damn good... Or, to put it simply, your sense of hearing was several times better than an ordinary human. (Assuming there were even humans on this planet, anyway.)
You could hear him talking... saying something behind you. And judging by the volume, it was obvious that he was deliberately speaking loud enough for you to hear.
The problem was...
You couldn't understand a damn thing he was saying. You didn't even know what language he was speaking! All you could do was guess that he might be telling you to stop, or perhaps trying to ask what the hell you were.
And honestly, you wanted to ask him the exact same thing. But you figured that he wouldn't understand a word you said, either...
So how the hell did everything end up like this?
Why did it feel as though you weren't even on your original world anymore?
Well...
That was because, just a few hours ago, you had died after finding out something you were never supposed to know. And the people who wanted you dead had followed you all the way to your apartment.
.
.
.
.
.
Today had been just another day of working a part-time job to earn enough money to put yourself through school.
It wasn't because your family was poor. Your parents hadn't divorced, and you certainly hadn't grown up in some kind of messed-up household.
Quite the opposite.
Your parents simply believed that you needed to learn how to live on your own. They wanted you to earn your own money, figure out how to take care of yourself, and learn how to survive in a world full of competition.
It wasn't because they didn't love you.
They wanted you to grow up and become capable of living in this harsh, competitive world on your own. And if things ever became too much, you could always talk to them or ask them for advice.
After finishing your shift, you headed home by taxi.
Unfortunately, the taxi couldn't take you all the way to your apartment, so you had to continue the rest of the journey on foot.
And that's when you happened to see something you absolutely should not have seen.
A drug deal.
A major dealer was in the middle of exchanging drugs along the route back to your apartment. And, of course, they happened to notice you just as you finished paying the taxi fare.
You noticed them, too. All you could do was keep your head down and walk. You didn't reach for your phone or any other communication device. You made it painfully obvious that you weren't interested, weren't involved, and had absolutely no intention of sticking your nose into their business.
You simply chose to walk as far away from them as possible. At that point, you were practically walking into the woods along the roadside.
You could feel their eyes on you. The pressure. The murderous intent.
The unmistakable feeling that a bullet could be put through your skull at any moment if you try something funny.
So you started walking faster. Or, hell, you might as well have been running.
Anything to get back to your apartment as quickly as possible.
Once you got inside, you shut the windows, closed the doors, and locked every single thing you could. And the very next thing you did was immediately message your parents and tell them everything you'd seen.
[If anything happens to me... please help me. Or at least try to find my body.]
You typed that final sentence with tears streaming down your face, terrified beyond words.
You had no idea that those would be your final words.
Your last message.
Your final goodbye.
Before the executioner came knocking at your door.
“I didn't wanna do this either... but the boss gave me the order. Forgive me, kid...”
The bullet pierced straight through your forehead in the dead of night. It ended your life quietly, without even giving you time to feel the pain.
Your body collapsed in front of the door. Your eyes remained wide open in shock.
And after that...
You knew nothing.
.
.
.
Or so you thought.
.
.
.
You jolted awake.
There was no vision of some divine temple waiting for you. Or no dramatic awakening in Hell, either. It was more like you'd simply fallen into a dreamless sleep for a while... And then woken up somewhere completely unfamiliar.
You looked around.
From what you could tell, you were in a city. And you were lying beneath a tree, which appeared to be some kind of public tree planted.
You slowly scanned your surroundings. The darkness wasn't an obstacle to your vision at all. In fact, you could see far better than you should have been able to.
That alone was enough to make you slightly suspicious. Your vision was unnaturally sharp. If you stared at or focused on something for a few seconds, your eyes would automatically magnify the target and sharpen the image on their own.
And then there was something else.
A faint scent.
A strangely enticing scent that made you feel something warm and wet gathering at the corners of your mouth. You quickly wiped away your drool with both hands.
And that's when you noticed them.
Your hands.
Your skin looked paler than usual.
Your fingernails had grown noticeably longer.
And they were sharp enough to be called claws.
“What the fuck is this?”
The words escaped your mouth before you could stop them. The shock of seeing what had happened to your body immediately changed your priorities.
Forget exploring the area. You needed to find a mirror. Or anything that could reflect your appearance.
You needed to know exactly what the hell you'd become.
“Is there... a puddle around here or something?”
You looked left. Then right.
Nothing but concrete walls and a chaotic mess of air-conditioning exhaust fans. You figured you'd probably woken up behind some building.
“Paler skin... claws... fuck... can I even retract these?”
You spent some time trying to retract your claws back into your fingers. And, surprisingly enough, it worked.
Meanwhile, your brain was finally starting to piece things together.
You had a pretty good idea of what you'd become. But you still needed a mirror. Or anything that could show you your own reflection.
You needed proof.
Because if you couldn't see it for yourself, you didn't want to accept it. Even if, deep down, you already knew.
You decided to wander around and explore, while doing your best to stay out of sight of the bald, horned creatures.
You suspected that you'd died... And been reincarnated into an anime world name Demon Slayer… But after taking a closer look at the city around you, you weren't so sure anymore.
The city was fairly modern, not quite on the level of the 2020s, but definitely far too advanced to be the world of Demon Slayer.
And the biggest reason you were convinced this probably wasn't the Demon Slayer world?
You kept seeing strange creatures wandering around the city. They looked vaguely human, except they had no hair and had horns growing from their heads instead and they were also ridiculously tall and muscular.
There was no way ordinary humans could be built that big, right?
You kept wandering until you finally decided to dig through a trash bin, it was humiliating as hell. But at least you had a better chance of finding a piece of glass to use as a mirror than wandering around looking for a puddle.
And before long... You found one.
A cracked mirror, that's enough.
Normal human eyes couldn't naturally be red, unless you had albinism. And even then, the eyes weren't actually red. The red appearance came from light reflecting off the blood vessels in the retina because of the lack of melanin in the iris.
But your eyes were Blood-red. They even seemed to glow faintly in the darkness. And your pupils had become narrow, vertical slits, resembling those of predators such as tigers or cats.
Your skin was noticeably paler, too.
And then there were those large, elongated fangs that became especially prominent whenever you smiled or opened your mouth.
You stared at your reflection for a moment.
“Okay... I've figured it out.” You paused.
“I'm a fucking Demon from that famous anime, Demon Slayer!!!”
And now came the next question. Where the hell were you?
Because you doubted the Hashira would be particularly thrilled to see some strange creature casually wandering around during both day and night. That was why you continued exploring while keeping yourself hidden from all strange creature's eyes.
Thankfully, it was nighttime… If you'd woken up during the day, there was a very good chance you'd have been discovered within the first few minutes.
You were still stuck beneath the shade of a tree, after all. And if you tried to leave that shade...
The sunlight would probably burn you alive.
The lives of these mysterious two-legged creatures with demonic horns were surprisingly similar to humans. They went to night club… they hung out and laughed together at restaurants… they walked along the sidewalks… they carried work bags home… or even went on walks with their friends.
In almost every way that mattered, they lived their lives and went about their daily activities almost exactly like humans.
And with physical strength several times that greater than humans, you could easily jump onto the roof of a building.
From there, you surveyed the city from above, curiosity getting the better of you as you tried to gather as much information as possible. From this height, the city looked like it was some kind of central hub. There was one major road branching out in four different directions. Each road had a large sign marking it.
Unfortunately...
You couldn't understand a single word written on any of them.
Right now, you were basically no different from a foreigner dropped into a country where they didn't speak the language.
“Where the hell am I even supposed to start?”
You cursed under your breath. You'd probably sighed for the hundredth time by now. The language was the only real obstacle standing between you and figuring out how to survive here.
But the scent of the creatures living on this planet?
All of them smelled like Marechi Blood.
This place was practically paradise for Demons like you. Except, you don't have intention to eat them, hell no. You want to be like Nezuko… friendly Demon won't eat living creatures. you'd probably need to find muzzle for their sake.
* Thud! *
A footstep sounds behind you.
Someone trying to sneak up on you. But unfortunately for him, your enhanced hearing picked up the shift in his weight with ease. You immediately turned toward the sound. And there he was……
A tall, muscular creature standing perfectly still behind you. He had two differently colored horns, one light blue and the other orange. His eyes were fixed on you, his expression impossible to read. You had no idea what was going through his mind.
But one thing was certain. You probably should have realized something was wrong the moment the scent of Marechi Blood started getting stronger.
.

Back to the Present:
And that was exactly why you were trying to get away from this mysterious creature with one hand clamped firmly over your nose.
You talking about pervert 007n7 got me curious, any other characters you think have pervert tendencies/habits? :3<
yes actually! while i believe that all characters are secretly perverted, there’s a few i think would be extraaaa sleazy!
007n7 - a little deeper into him, since he’s a little antisocial, he sees most people as ‘characters’ rather than humans. plus he’s a total porn-addict.
builderman - the type to get a hugeee rush out of controlling you, especially if you aren’t in the position to stop him. even more if no one will believe you.
clockwork - sadomasochist. fucks up his wires for the fun of it and always makes you clean them up. whether you like it or not, you’re gonna pleasure him.
noli - the control freak EVER !!! lovess the fact that he can easily get into your mind and make you do his bidding. the type of guy to get turned on no matter what u do.
shedletsky/telamon - corrupted god, we know this. likes to use his power into pressuring you to obey him. really likes seeing you get flustered/frustrated.
i have a few ideas for phighting too !
skateboard - ofcofc the sleaze-bag everrr ! usually uses your addiction against you to keep you hooked to him . . and if you aren’t addicted yet he’ll make it happen.
scythe - she’s used to being in power, and she isn’t afraid of using it to get what she wants. even if she does do reprehensible shit, who’s gonna stop her? you?
subspace - don’t even get me started. he’s used to being seen as weak because of his illness. bc of this he’s a total sadist, gets off to you being scared of him.
again, EVERYONE is a pervert to me! its just that some have a bit more self-control then these ones 🪽🪽🪽
partners who seemed so, so respectful of your wishes whenever you tell them to use a condom. of course, they understand the risks! and then see why you would want that . . but that doesn’t mean they agree.
they’ll play along at first, the rubber stretching over their cock as they prepare to fuck you.
it feels different than normal more . . detached. they hate it. they can feel the pulse of your walls, the clench of your pussy . . but its not enough. no matter how many times they fuck you, it doesn’t feel right.
their cum is wasted in those shitty little sacks, pointless. that’s why after about 2 rounds, they pull out, taking the already used condoms and placing them above your pussy, letting the cum drip out.
they wring the rubber for every last drop, making sure to finger it back inside your pussy.
you’re too blissed out to fight back, hardly even registering what they’re doing until they slide back inside of you, this time without the condom.
even if their cum is technically already inside of you, there’s nothing wrong with fucking you raw for good measure — maybe they can even prove to you how ‘useless’ those silly little condoms are.
haven’t checked up on the phighting x reader content in a while as a former boombox x reader writer, I wonder if anyone has done yansword x reader
slowly killing off members of your faction (maybe I think factions are friend groups in the AU) until it’s only you, and overwealmed by grief you are, you go to your friend rocket, and sword has to make a choice.
