I Reincarnated into a World with Flipped Gender Roles and Wanted to Build a Harem! …But Then All the Heroines Turned into Yanderes and My Life Became a Quagmire! - Vol 1 Chapter 1
Vol 1 Chapter 1 – Awakening
On my way home from the company, I was hit by a truck.
And just like that, I was dead.
Cause of death: excessive blood loss from a traffic accident.
Well, I’m pretty sure it was instantaneous.
I didn’t even feel any pain.
Still, I think my life was a pretty unlucky one.
To meet my parents’ expectations, I never made any friends or got a girlfriend, just studied my ass off to get into the medical school of a super-famous national university and become a doctor. So far, so good, but…
That university hospital was a sweatshop that would put any black company to shame… Naturally, there was no overtime pay and no days off.
And just when my mind and body were in tatters but I was finally getting used to the job, this happens!
And I was working right up until the moment I died! …I can’t take it anymore… I want to die.
But I’m already dead, so I can’t die!
Damn it all!!!
………………………Huh? Wait. Isn’t something… off? Why am I conscious when I’m supposed to be dead?
And where the hell am I?
When I opened my eyes, I was in a place I didn’t recognize.
The first things I saw were a white ceiling and a fluorescent light.
Then, a familiar smell, like disinfectant, tickled my nose… Is this a hospital room?
It seemed I was lying on a bed.
Just as I tried to sit up and look around, the door suddenly opened.
I was speechless at the person standing there.
…Because there was an angel.
Not that she had wings or a halo or anything like that. She was just so cute, she looked like an angel.
A golden-haired, blue-eyed girl was looking this way with a surprised expression.
…Cute.
But why does she look so surprised? Did she not expect me to be awake?
No, if that were the case, she should be even more shocked.
Maybe she thinks I’m a ghost or something…
Just as I was thinking it would be rude not to say something and tried to speak, the girl opened her mouth.
“Onii-sama!”
What?! What did she just say?! I think I heard Onii-sama…
I don’t have a little sister.
If I did, I’m confident I’d brag about her constantly.
Then who is she talking about? If she’s not my sister… could it be…
A certain possibility surfaced in my mind.
I was supposed to have died after being hit by a truck.
And when I woke up, I was in an unfamiliar place where I met a beautiful, golden-haired girl.
So, is this what I think it is?
The whole reincarnation-in-another-world thing?!
Yes! The other-world reincarnation I’ve always dreamed of!
Now I might finally get a girlfriend!! No, no, that’s not it! That’s not what’s important!!
Since I have no idea what’s going on, it’s probably best not to do anything rash. Yeah.
For now, I’ll just wait and see.
“Onii-sama! Are you alright?!”
The girl’s voice echoed again.
It seems she really is referring to me as Onii-sama.
“Um…”
“Oh, I’m so sorry! I was just so happy, I couldn’t help but hug you!”
“No, it’s fine. It’s okay, don’t worry about it…”
“Huh?!”
The angelic girl looked at me, stunned.
…Did I say something that shocking?
“Onii-sama, you’re not… mad at me? For hugging you?”
The girl asked, a sad expression on her face.
“What?! Of course I wouldn’t get mad over a little hug.”
“But… you’re always getting mad at me, Onii-sama… I thought you must hate me… And besides, it seems that just being around a woman is enough to fill a man with utter disgust…”
Seriously…? You’ve got to be kidding me…
Could it be that this is another world, but it’s one of those patterns where chastity concepts are flipped?!
And judging from what she said, it sounds like all men have some kind of gynophobia.
“No, I promise you that’s not true, so don’t worry. More importantly, I’m sorry. It seems I have some kind of amnesia, and I can’t even remember your name. Would you mind telling me?”
I decided to ask for her name while putting on an apologetic face.
Honestly, at this rate, I can’t even hold a proper conversation.
“No… amnesia… you can’t be…”
The girl stared at me with a look of disbelief.
Well, that’s a natural reaction.
“It’s true. I’m sorry, but it would be a huge help if you could tell me about yourself…”
“I understand…”
ーーーーーーーーーーーーーーーー
About a week has passed since I woke up.
And in this week, I’ve come to understand quite a bit about this world.
First, it seems my name is Yuuma Kisaragi.
The girl in front of me is my little sister, Yukina Kisaragi.
Apparently, I suffered a severe head injury in a traffic accident and was in a critical, unconscious state.
Our mother gave birth to me and Yukina through in-vitro fertilization using a sperm bank, but she passed away from an illness last year.
This world… it seems to be a parallel world where chastity concepts are reversed, just as I suspected.
Men are apparently seen as objects of sexual desire by all women, and as a result, men seem to dislike women and even hate being near them.
Perhaps because of that, men haven’t advanced much in society and are basically all shut-ins who stay at home…
Furthermore, about my appearance… it’s embarrassing to say it myself, but I was extremely handsome.
How handsome? So handsome that a fan club for me has already formed inside this very hospital.
Well, it seems that in this world, women are so starved that just being a man is enough to make every last one of them turn their heads…
I’m a completely over-specced pretty boy.
And, just as I thought, the number of men is apparently low.
The male-to-female ratio is said to be about 1:1000.
By the way, my age in this world is 16, I’m tall—probably around 180 cm.
In other words, all the conditions are in place for me to fully enjoy the youth I couldn’t have in my previous life.
“Hey, Yukina. My injuries are healing, but when can I get out of the hospital?”
I asked Yukina.
She answered with a troubled look on her face.
“About that… your condition has stabilized, so it should be about time for you to be discharged, but the doctor says you still need to rest…”
“Is that so… Well, can’t be helped then.”
“Yes… but summer vacation is starting soon, and they said you should be able to leave by then!”
“Come to think of it, what month is it now?”
“It’s July.”
“Huh, so it’s that time of year.”
“Yes! It seems there are more hot days this year than last, and some regions are already seeing temperatures over 35 degrees.”
“Seriously…? That’s not global warming, that’s just abnormal weather.”
“I completely agree.”
As we were talking, the clock struck noon, and it was time for lunch.
As usual, a beautiful nurse in a needlessly revealing uniform brought my lunch.
Having figured out that I don’t have much fear toward women, the nurses at this hospital have been actively making passes at me.
And each time, Yukina drives them away with a demonic look on her face, which has become a daily routine.
It looks like today’s meal is a grilled fish set.
As always, an appetizing aroma wafts from the tray.
Today’s menu consists of white rice, miso soup, salt-grilled salmon, a rolled omelet, spinach ohitashi, and fruit jelly for dessert.
Yep, no complaints.
You can feel the care put not only into the taste, but the presentation as well.
The hospital I worked at in my past life never served food this luxurious or delicious, so I was genuinely happy.
“Alright, Onii-sama, please say ‘aah’!”
“It’s the same thing every day, but I can eat by myself now, so you don’t have to feed me…”
As I said that, Yukina’s eyes welled up with tears and her face grew sad.
Ugh… the guilt…
I want to avoid doing anything that makes Yukina sad if I can help it.
But this is just too embarrassing…
“No… good?”
“No… it’s not that…”
Yukina asked while looking up at me with pleading eyes, so I caved and gave her the okay.
“Thank you!”
Yukina joyfully picked up the chopsticks and, one after another, brought the food to my mouth.
And when I opened my mouth to take a bite, Yukina had a blissful look on her face.
After that, I just let Yukina feed me.
Every single day, without fail, Yukina comes to my hospital room and takes care of me.
There’s no way I could treat a sister like that harshly.
“That was delicious. Thank you for everything, always.”
I put on a smile and spoke my words of gratitude.
“No, it’s because I like doing it…”
“Even so, it really does make me happy. You’re a huge help, thank you.”
I told her how I felt from the bottom of my heart.
“Yes…///”
Yukina looked down, embarrassed.
Lunch was over, and Yukina had gone home.
And I was about to put a certain plan I’d been thinking about all week into action.
The plan was to become friends with the girl in the next room, a Miss Kurokawa.
While Yukina was visiting me every day, I had been secretly looking into Miss Kurokawa.
And I’d learned something.
It seems that Miss Kurokawa is a student at the same high school I attend in this world.
And apparently, she’s in the same class as me.
This is the first step to living out a rose-colored youth, I thought.
“Alright, let’s do this…!”
I steeled my resolve and tried to get out of bed.
But as I did, a slight pain shot through my body.
“Ugh… damn… Guess I’m not fully healed yet…”
Enduring the pain, I stood up and headed for the private room next door.
Then, I knocked on the door.
knock, knock
“Yes, who is it?”
“It’s Kisaragi. I’d like to talk for a minute. Can I come in?”
“Wha-?! W-wait! I’m changing right now! Could you please wait just a little bit?”
“Oh, sure, I don’t mind at all.”
“O-o-o-okay! Th-th-then, please wait for about five minutes!!!!”
“Got it.”
Five minutes later…
“Excuse me…”
I timidly entered Miss Kurokawa’s hospital room.
“Y-yes…”
There stood a beautiful girl in pajamas.
She had long, black hair that fell to her shoulders, and she was probably about 150cm tall. Her face was small like a little animal’s, and her big, round eyes were very cute.
Her skin was so white it was almost translucent, and while she was petite, her chest was large.
The so-called ‘petite and busty’ type.
I found myself staring, captivated.
At that, Miss Kurokawa’s face turned bright red and she averted her eyes.
Crap! I stared too much! Before I could frantically apologize, she spoke to me.
“Ah-ah-ah! Um, so, what did you want to talk about…”
“Oh, right…”
Though nervous, I decided to get to the point.
“The thing is, I… I got amnesia from the accident, so I don’t remember much of anything. Then I heard from one of the nurses that you, Miss Kurokawa, who goes to the same high school, were in the room next door… What was I like at school?”
“Whaaat?! Amnesia?! Are you okay?! And to think you were in the room right next to me, Kisaragi-kun… This is too perfect! Ah! I’m sorry! For suddenly shouting like that…”
Miss Kurokawa looked extremely surprised, and partway through her excitement, her breathing grew heavy.
“No, don’t worry about it. More importantly, I’d be happy if you could tell me…”
“Yes… If someone like me is good enough, I’ll tell you anything!”
“Thanks. Well then, could you start by introducing yourself?”
“Yes. My name is Ayano Kurokawa. I like cheesecake and, um, Kikisararagigigigi-kun, and there aren’t any foods I particularly dislike! My hobby is reading, and it’s nice to meet you!!!”
Seriously, her innocent reaction is too cute, and she’s way too easy!
She’s already totally in love with me!!
Besides, what the heck is a ‘Kisararagigigigi-kun’?!
She’s not hiding the fact that she likes me at all!
She just said it herself!
If this were a rom-com, this would be the part where I say ‘I like you too,’ we start dating, and the story ends!
“N-nice to meet you too. I’m Yuuma Kisaragi. My favorite foods are omelet rice and sweets in general, and I dislike green peppers and spicy things. And, well, I don’t really have any hobbies. I’ll start remembering them from now on.”
I managed a greeting, though I was a bit taken aback by Miss Kurokawa’s reaction.
“Wow, I can’t believe I’m actually talking to you, Kisaragi-kun… It’s like a dream… I could die happy now.”
“Whoa, hey, you can’t die…”
“Ah?! I’m sorry… I just got so happy…”
“Well, whatever… By the way, Kurokawa-san, what do you think of me?”
“Huh?”
“I mean, what do you think about me…”
“W-well, that’s obvious, isn’t it? Of course I’m madly in love with you…/// I’m in a situation where I’m desperately suppressing the urge to jump you, kiss you, and make babies with you right now!”
“I see… Thanks. I think I could come to like you too, Kurokawa-san.”
“Huh…? What do you mean by that?”
“Hm? I mean exactly what I said.”
“Oohh, Kisaragi-kun, are you… a natural-born playboy?! …Ah, I can’t take it anymore~ you’re too cool… I want to kiss you.”
“Whoa, whoa, hold on. What part of that conversation was cool?”
“All of it!”
“Is that so… I don’t really get it, but, thanks?”
“Yes! Thank you very much!!”
“Haha, anyway, what was I like at school?”
I steered the conversation back to the main topic.
“Yes! You were everyone’s idol, or maybe I should say, you were everyone’s fap material! It’s not just that there are no other boys at school besides you, Kisaragi-kun, but being so incredibly handsome is just too unfair! And your grades are excellent, you’re great at sports… you’re basically a perfect superhuman!!”
“I-is that so… That’s kind of amazing…”
“You’re practically a god!!!”
“It goes that far…?”
I was a little put off by the part about being the whole school’s fap material, but it seemed like this was normal in this world.
“Yes! But at school, I could never bring myself to talk to you, Kisaragi-kun. Because… everyone was after you… There was always a fight over you. And your sister, Yukina-san, who’s in the middle school division, would often lead her personal guard to protect you from the other girls…”
“What kind of army is that…”
“Yes, so the people who gave up on you, Kisaragi-kun, would secretly get off to you in the shadows. I was one of them, but…”
“Seriously…?”
“Yes…”
The girls in this world are all perverts…
Kurokawa looked so prim and proper on the outside, but on the inside, she was a huge perv.
Probably, all the girls in this world are perverts just like her.
But I don’t mind being liked by a cute girl like this.
Still, I can’t believe a cute girl like Kurokawa would have feelings for someone like me.
It really is like a dream.
I pinched my cheek.
It hurt.
Which means this is reality.
In other words, it seems I really am super popular in this world.
“Ah, um! Is something wrong?!”
Seeing me suddenly pinch my cheek, Kurokawa looked worried.
“Ah, sorry. It’s nothing…”
“I-I see…”
“Well, I should probably be getting back. I’ll come again tomorrow. Bye-bye…”
“Ah, um! I have one last request!!”
“Eh?”
“Th-that is… could you call me by my first name…? Without any honorifics, if possible… Would that be… too much?”
“What?!”
“Ah! I’m sorry! That was so forward of me! Please forget I said anything…”
“No, it’s totally fine. Actually, I’d be happy to…”
“Eh…?”
“Ayano…”
“Hauu…”
“Is that okay?”
“Yes… Thank you so much…///”
“Well then, one more time. Bye-bye.”
“Yes… Bye-bye…”
And so, Ayano and I parted ways.
However, at that time, I had underestimated the strength of the girls’ libido and the depth of their love in this world.
To think that Ayano would gradually turn into a yandere…
