Yandere Chisome

My sister, Chisome, is strong.

To the point where, if one were to put it in terms of combat games, it has the ability to bring everything to nothing with overwhelming attack and annihilation power.

I'll say this many times, Chisome is strong.

That's why she always rushes to protect me when I'm in danger.

"......-!?!?"

That's what I saw when I was about to take a bath.

With a black-painted body, waiting for that moment to come *isitnow*isitnow*, the instant that fellow saw me, it made a rustling sound and started moving.

"Uwwwoooohhhh--!?"

That guy's name is G, and it is the worst being to terrorize men and women alike.

As I said earlier, I was about to take a bath, so I was completely naked and had no defensive power.

Perhaps because I let out a pathetic scream, footsteps were immediately heard coming from the other side of the door.

"Nii-san!?"

Of course, the one who appeared was Chisome, my beloved younger sister.

She instantly sensed the existence that I was afraid of, and with a furious expression as if she wouldn't even allow it to stay there, she held up her hand towards G.

"Die"

At that moment, a black mist wriggled like a giant snake and wrapped around G.

I wonder if it feels like it's grinding instead of being eaten... Apart from Kuro Chisome who is doing the attacking, Chisome, she hugged me and watched how things unfolded... a, so you're not going to do that this time I see. (Taiga)

"Phew... annihilation complete."

"... That was an excellent job."

G, you're simply out of luck.

However, while I remembered that I was completely naked without wearing a towel or anything, Chisome looked back at me and gradually turned her gaze downwards.. I couldn't take it anymore and ran into the bathroom.

"Is not as if you have to run away you know Nii-san"

"... I'm sorry for showing you such a lame thing."

"That's not true. It was quite splendid you know!!"

"Eei! Now return from whence you came!!"

"Ye~s♪"

I'm grateful for saving me from G, but the embarrassment of having my little sister see my important part is awkward...Well, it's about Chisome, so she wouldn't worry about it at all, but even so, my damage was great.

After that, after I got out of the bath, I was treated to dinner.

“Jeez Nii-san, are you still worried about the things before?”

"... No, it's okay now. How do I say this, Even though Chisome doesn't seem to care at all but I always seem to care about it is somehow, kind of, you know, just what I think is all."

"That's right that's right. When I came here, we often used to take baths together, so it's too late to say that now!"

"-....."

To tell the truth, Chisome, who had just arrived, took a bath with me many times.

Because Chisome, who was still emotionally unstable, invited me to join her, and seeing how she was at that time, it was impossible to refuse.

(well its only obvious if one were to get stared at in that way with those clinging-like eyes....)

But... that to me had also become one of my precious memories.

"...uh, there is also one of my embarrassing memories but... aren't I quite frantic that time? Like I tried to meet Chisome's request as much as possible."

"a... that's right isn't it. Thinking much about it, I really did made you worry. I'm sor――"

"Don't apologize. It's true that I was frantic, but that is also one of my precious memories with Chisome."

"...Nii-san♪"

Look, Kuro Chisome is also nodding as well.

(Actually... Chisome was also my favorite character, and beside it was such a thing where one would wonder if experiencing a bath with a beautiful girl with outstanding style can happen even if one were to use up all one's happiness in life.)

Behind Chisome, who was purely happy, I was thinking about something peculiar to adolescent boys.

"Nii-san?"

"-.... Ou"

"Is anything wrong?"

I pretended to be normal, saying that there was nothing wrong with Chisome tilting her head.

“After eating, is it fine if I go to my Nii-san’s room?”

"I don't really mind y'know."

"yay♪"

Hmmm, Chisome is the only person in the world who would be happy to be allowed to go to her brother's room, I think?

Well to me Chisome is cuter than anything and anyone else, so it's all good, its to the level where I want to brag about it to everyone who has a sister that my sister is this cute.

(... well yea I guess it is for this reason why people calling me a siscon.)

a first-class siscon, I can say whatever I want is what I feel by being that.

After having dinner, Chisome came to the room as promised after the two of us finished our housework.

It was the usual position of Chisome sitting together next to me on the bed, and holding my arm tightly.

"So, is there something you want to talk about?"

"Un. Can I get right to it?

"Sure"

With light feelings I nodded.

"Why does Nii-san had always and always, gives me the words I want you to say?"

"... words I want you to say?"

Chisome nods and continues.

"No matter when I'm having fun or when I'm feeling a little down, my Nii-san always gives me exactly the words I want. Even when it's casual, you always gives me words that make me happy... nee why is that??"

".....Uhhh"

I got stared at, but when I was told that, I ended up at a loss for words.

While being aware of that bastard Taiga, it's true that when I first met Chisome, I wanted to do something about her from the bottom of my heart, but I was careful not to step on a landmine... As of now, particularly whether should I better say this or something I haven't really thought about it that far. [TL note: Taiga from the game.]

"To tell the truth, its not as if I was thinking about anything, because there is also a part where I was like having a spinal reflex."

"While sometimes having a spinal reflex you are saying things like I'm cute to me?"

"You're right"

"-....... It is that side of you, Nii-san!"

"Nono, if anyone has such a cute sister, then about everyone will be like this right!"

"....Uu!!"

[TL note: the mc, in the above conversation, is being awkward.]

If this was just Taiga born in this world....Even without doing the 'assault' there shouldn't be much to say.

I think it's only because I know the secrets of this world and the secrets hidden in Chisome that I can say it, and I think the biggest reason is that I simply love Chisome.

"……Un?" (Taiga)

When I was talking to Chisome like that, In the corner of my vision, Kuro Chisome is reading a popular romantic comedy manga, I never thought I'd see her like this, so I'm deeply moved.

"Well, you just have to give up. This was already decided when I became Chisome's older brother. I won't hand over this role to anyone else. I'll be by your side hereafter as long as Chisome wants it, you got that?"

"......un.....Un!"

That is the declaration of my true feelings.

Even when embarrassed, Chisome nodded with a beautiful smile and leaned on my shoulder as if to put her head on it.

"...... that's right Chisome"

"What~?"

Her voice is completely hoarse, but... While thinking it was a good chance to ask, once again there was something I wanted to ask her.

In the end it was not revealed in the original work, but because I was reborn as Taiga like this, I was able to ask Chisome directly.

"How did Chisome come to have that mysterious power?"

"......U~n"

At my question, Chisome crossed her arms and began to think.

"......I don't really know"

"......I see."

In the end, that was Chisome's answer.

It's not like I've heard anything about it but, still, it's a little disappointing because I thought it would be an opportunity to learn something hidden in this world.

"It's been like this since I can remember... and after that everyone rejected me... and I became alone――"

I gently hugged Chisome's head, whose voice was gradually sinking, into my chest.

Although it was out of curiosity, I'm still not being thoughtful enough huh...... For Chisome, the past was the number one cause of why she would lose her mind and yet.

"...... I made my Nii-san worried again didn't I"

"No, it was my bad just now."

"That's not true. Fufu, Even if I remember the past and feel sad, my Nii-san will hold me like this."

You have a knack for always being in a good mood, I said as I *pon*pon* patted Chisome's back.

"Nii-san is a really strange person isn't he. I feel like you're definitely different from anyone I've ever met. It's like, someone from another world."

"That could be it you know? Maybe I'm an ally of justice who appeared to save Chisome from loneliness."

I tried to say something a little cool to try to look good.

Chisome raised her face and widened her eyes for a moment, but she immediately loosened her cheeks and smiled again.

"Ahaha... maybe so. If that's the case, thank you Nii-san... For saving me and for appearing in front of me, Thank you."

"......Chisomee!!"

"a, Nii-san cried!?"

Its only obvious I was sure to cry If you said something that made me so happy while being like that!

Chisome doesn't notice my truth.... Still, this was the first time Chisome ever said something like this.

In my sister's words, I feel like I've been affirmed the meaning of being born in this world and that makes me very happy.
