Chapter 1: Encounter with Chisome
"Ni-Nice to meet you...... my name is Chisome......"
"......Nice to meet you.......---!!??!?!"
It was when I'm still in Junior High School, that I met a certain girl.
That all of a sudden, my Father brought a girl to our home and said she is going to be my younger sister.
She was a girl with long, jet-black hair and bright red eyes, and she was filled with an indescribable eerie feeling.
"Is......there something......wrong..?"
When I suddenly held my head and crouched down, she... Chisome tried to reach out with her hand and withdrew.
Well, there was no need for her to worry about me, so she took back her hands, but I could sense a slight hint of fear from Chisome as to whether it was okay for her to touch me.
(......Oi Oi, is this for real? no way...... did I just got--!?)
As If, it's a lie, it's impossible, words like that pop up in my mind and disappear.
By facing Chisome, one memory that was sleeping inside me was awakened, and I clearly recognized one single fact.
(I...... I really just got reincarnated!?)
Right, I just realized that I'm a reincarnated person.
The sudden memory flow is making me panic like this, but I soon calmed down, probably because I had some spare brain capacity.
That said, I wanted a little more time to ponder and process all this, so I briefly introduced myself.
"Its Rikudou Taiga. Lets get along Chisome."
"Please....... do....."
She pulled her hand as soon as she reaches out.
While smiling wryly at her appearance, I forced her to hold my hand...and my expectation that I'm a reincarnated person turned into a certainty.
The moment I held Chisome's hand, there was something behind her that I couldn't see.
Aside from the wriggling black things like waves, I certainly saw something terrifying with the same bright red eyes as Chisome.
"... Phew."
After leading Chisome to the room prepared in advance, I returned to my room.
By being alone, I once again organized this world and myself in my head.
"This world is probably... no, it's definitely a world of 'Byouai'."
Byouai... Just to put it simply, there was a game called "I love you sickly".
As you can see from the title, this is a dating simulation game that appeared as if riding on the trend when the yandere genre established an era.
The game was originally marketed as a romantic comedy, but all the heroines were yandere, and although it was said to have a strong horror flavor, the story and settings were generally well received and become quite a topic.
Of course, as a romantic comedy maniac, I couldn't help but play this game, even sparing time for sleep.
"... Haaaah."
The reason why I let out a sigh unconsciously is simple, and that is that Chisome and I are characters who also appeared in the game... However, Taiga was already dead at the start of the original work, and that's why. It's the cause of my sighs.
"Rikudou Taiga doesn't appear in the original work, because he's dead. And killing Taiga like that is Rikudou Chisome."
In the original story, Taiga has already left, and the reason for that is that Chisome killed him.
Well, putting me aside for now, the problem is Chisome.
Rikudou Chisome is also depicted on the game package, and is closely related to the story, but she is not the heroine... No, since there are options, the treatment itself may be the heroine, but although you can go into her route, there is only a bad ending of being killed.
"... I was really amazed back then and be like 'what the heck is this??'"
It's true that the game itself is in the genre of romantic comedy, and it's strange that all the other girls are yanderes, but from a common sense perspective, they're normal girls.
However, Chisome was like a bug character prepared by development team.
First of all, Chisome has something that other girls don't have... it's that she's genuinely a monster with alien powers.
"But she doesn't look anything like... wait, huh? If I remember it right, the original Chisome was like a gal..." (gyaru)
The gal I remember from the game doesn't look anything like that timid and nervous Chisome.... Well, fine. Putting that aside for later.
Something black that I felt in her, that is the true identity of the terrifying monster that Chisome possesses and keeps in the shadows.
Why is there a girl like her in a romantic comedy game?
The development team comment was that, simply speaking, in this game, since you are just dealing with a different kind of yandere, we thought, it would be nice to have a scary child who would definitely kill if you were to enter her route.
"The vector of fear is just too different. Even if aspect of supernatural powers are used, its not as if that is the main appeal of the game, and just by going Chisome's route, all it does is that you are just going to get eaten and the strangeness exposed."
If you go down that route, one will just end up in a bottomless pit.
Nonetheless, even though she is such a bloody character, she is ranked first in character popularity polls.
First of all, her appearance was too enthusiastic, and the gap between her appearance and her hidden supernatural power struck a chord with fans above all else.
Chisome was such a popular character that it gave birth to many people with perverted thoughts, such as being eaten by such a child.
"Yeah right..... she was also my favorite..."
Yep, I also liked her.
In addition to the usual Chisome appearance, the overall black and evil looking monster inside Chisome was also the best visual.
No, rather, not inside but behind her... Chisome as a monster is also really beautiful and has an outstanding style, and I also thought a lot that if I was sandwiched between Chisome on the front and back, I will be really happy.
"I mean, it was to the point where there was a lot of fanfictions about that was born..."
Chisome really was that popular.
"... all right then, what to do... or rather, I really don't want to die."
My heart is strangely calm even though my life already is in danger at the moment... I wonder if I'm thinking about the future while wondering about that.
Well, to some extent, I have more or less an idea on how I should do this, and in a sense, my existence is like being responsible for how Chisome grows.
"Chisome wasn't like that from the beginning. It's all because of Taiga and his shitty old man."
As the game narration goes, such a thing like best friend or even a friend, Chisome, originally and now, doesn't have any at all.
Just like what I felt when I touched her, my instincts warn me of her strangeness, because of that no one tried to approach her.
In that way, Taiga and that shitty old man took the worst action against her, who had no interaction with anyone and was only feared.
"... She's going to get assaulted alright."
From the stage of junior high school, Chisome's appearance has both a perfect beauty and a plump sex appeal that invites men's lust.
Even though I should praise myself for overcoming my fear of Chisome, I was in the mood to give lots of retorts as to why he, Taiga, sexually assaults Chisome and gives her the final despair.
"It is explained that Chisome was thinking everything in the world was despair, and everything there is in the world was enemy. In that case, why don't I just come up with something about Chisome before someone made her think that way? Luckily, I like Chisome!"
[TL Note: he is talking about the game Chisome in Senior High School version, not her childhood. Right now, Chisome is still in Junior High School and not a gal.]
If I decide it like that, the only thing left is action.
I immediately went to Chisome's room and knocked on her door.
"G-go ahead....."
"I'm entering~"
It's still a drab, plain-like room, but I got a little emotional when I think that it's going to be a gal-like bright room from now.
The crimson eyes that stare at me are a little scary, but... I think she's a really beautiful girl.
"sorry for being sudden? Because I want to get along with Chisome now that we're going to be a family."
"You... want to get along with... me...?"
"Yea, I'm really excited. I've been an only child until now, so when I'm thinking of having such a cute little sister, I got really excited."
"C-cu-cut--!?"
It seems to be she's never been called cute at all, and Chisome's face turned red.
(How did that shitty old man find this child? I wonder if I'll hear anything about that in the future.)
Aaah yea, right right. I've been saying shitty old man shitty old man for a while now, but the family relationship in this house has already collapsed.
That's why calling that guy shitty old man is already more than enough.
I smiled wryly at Chisome's face that glanced at my face and held out my hand again.
"Let's go and shake hands again"
"a……"
She reaches out her hand but immediately withdrew, but I took it, her hand, and held it.
At that moment, the black monster that emerges behind Chisome stares at me.
I think its fine to be honest about this? although my heart is seriously stirred in fear.... I'm not afraid because I can see the black kind of Chisome-like more clearly than before.
"Lets get along with you too."
"e……"
Surprised Chisome, and Kuro Chisome behind her also had wide eyes that I had never seen before in a game.
For the time being, its fine not to let her know anything, even I don't really know what I should be doing, so it's mutual.
"......O-……onii……chan."
"--!?"
Onii-chan... did she just say onii-chan!?
Chisome said that embarrassingly, but her eyes gradually grew wet and tears began to spill out.
I immediately hugged Chisome, and it seems it wasn't a wrong action.
".... is touching fine?"[TL Note: to Kuro Chisome.]
Can I even touch her?
With that in mind, I reached out my hand to her... and though I was able to touch her, her body was frighteningly cold.
Kuro Chisome, whose eyes were rounder than before, was also cute, and I naturally hugged her too.
“…………”
Kuro Chisome didn't say anything, but she hugged me back just like how Chisome did.
Not bad at all... yep its not bad at all, right, I know I sounds a little nasty and creepy, but I wanted to protect these girls as their big brother.
I'm Taiga Rikudou, but I have no intention of becoming like him... I will protect Chisome's heart with my own will.
That became my goal when I was reborn in this world.
-------
Several months have passed since then.
My fucking old man died but I lived.
