Recently, when I suddenly wake up at night, I like to watch at a certain moment.

That is spread out in front of my eyes now; if I were to specifically explain it, it's the figure of Nii-san and Mashiro sleeping while embracing each other happily.

"Somehow, it's nice isn't it, this kind of thing"

Nii-san and Mashiro are precious existence to me.

It's unmistakably an existence that I have to protect no matter what happens, and if it were to end up disappearing, I myself would end up broken I think....... That's how important their existence is.

Jealous regarding Nii-san and Mashiro hugging each other? No way I'm going to do so; I mean, Mashiro is also me, that's why.

"The time is...... 3 o'clock. I ended up waking up at a delicate time aren't I."

I muttered so and got out of bed and headed to the living room.

When I poured cold water into the glass and slowly let it go down my throat, I couldn't help but feel that my remaining drowsiness was blown away, but I was thirsty so it couldn't be helped.

"......Aah delicious."

I put down the glass and think back to today.

Misora-senpai and Yuika-senpai came when I was waiting for Nii-san, and I have gotten along so well with those two that even I myself was surprised by it.

Though Yuika-senpai is still the only one I let know about Mashiro, it's not a joke when I tell Nii-san that I think it might be okay to have to tell Misora-senpai someday.

"Will they betray or will they not betray, it's too blunt a reason on top of making friends, but it's precious to us."

I don't care about betrayal itself, but I'm always thinking to the extent of eating them without hesitation if they do something to Nii-san.

But those two are so crazy that I don't really worry about it.

"......Fufuu, they are crazy; is it a bit cruel to say that, I wonder~"

I smiled wryly.

However, this alone is true that as far as those two are concerned, they are clearly so strange than anyone I've met up until now that I end up thinking like so, and of course in a good way okay.

"Nevertheless, Byouai......huh~ it's a really strange feeling."

The things about this world that I have Nii-san taught me were truly full of surprises.

In the first place, it's natural that there's no way I can think that this world I myself live in is such a thing as a game world, but it was also quite refreshing to hear that the moment I put my hands on her, I would go at full speed to the dead end, the landmine heroine.

"As long as one is the heroine, you want her to be a cute girl right~."

Well, I have absolute confidence in my appearance anyway, I'm also cute and beautiful, and furthermore, I'm proud of my sexy figure as well.

Of course, the only one who can touch this body is Nii-san, but still, the heroine who promises death is, something like this......I also thought it suited me well.

"In the game, I was a monster who didn't bond with anyone and would eat and kill anyone who approached me. But in this world, I am tied to Nii-san, and I am also not swayed by my own power......isn't that――proof that I can't fall in love with someone other than Nii-san?"

It means that I've recently started thinking about things like that, too.

Although I say Nii-san, it's the current Nii-san, and perhaps it's not about the Nii-san I originally met.

"From now on too, Mashiro and I will always be by Nii-san's side. Spending our time of what you call days as students, becoming adults, marrying Nii-san and building a happy family......fufu♪ Just thinking about that alone makes me happy every day right~"

We are still young, precisely why our bodies tremble with great joy at the happiness of being able to spend more and more time together with our loved one.

I'm filled with happiness like this, but I have only one thing to think about lately.

"......Mother huh"

I have few memories of my mother.

I know that person hated me anyway, if anything even the people around can't help it, but they were the same as my mother.

Rather than being roughly a mother and daughter, the treatment was more like a troublesome pet that she had no choice but to keep, but even so, because she was there, I was able to meet Nii-san.

"......We have no intention of meeting each other and we also have no intention of getting along well. To say nothing of the family bond, it has already been severed. Even so, I came to think like, maybe it's okay to also tell that person that, I'm happy now you know, is probably.......thanks to Nii-san."

That person......my mother is no longer an object of hatred for me.

To the extent that I feel it's a waste to embrace such negative emotions like that, I'm happy now.

"Now~ then, something or other has ended up keeping me absorbed in my thoughts for about thirty minutes, didn't it."

It's 3:30, as expected, it's bad for my skin if I don't go back to sleep soon.

When, however, another thing calls to my mind as I stand still——that is, once again, this world is a story centered on yandere girls; doesn't that, in other words, mean I'm also going to become a yandere too? It's a simple question.

"I don't particularly think of let's bind Nii-san, I just want to monopolize him. I don't want to cause trouble for Nii-san anyway and I have no complaints about what he does......I just want to monopolize him, really. I have no intention of meddling in Nii-san's friendship relationship, so even if pretty women like Misora-senpai and Yuika-senpai became acquaintances, I won't do things like get jealous......I'm just, if I have Nii-san by my side, then that's fine whatsoever, and really I just want to at any rate keep him to myself anyway?"

......Un?

I felt something was caught in the middle of my words, but I thought it didn't particularly matter and went back to my room.

Nii-san and Mashiro were still asleep on the bed, but Nii-san's position had changed a little.

“Could it be that Nii-san......Ahaa♪”

If he became in a position where he could hug me and fall asleep, it meant that, in other words, he was waiting for me, right?

In that case, I immediately laid down next to Nii-san.

"......suu......haa"

While I hugged Nii-san as hard as I could, I sniffed that body odor.

Doing so, the scent of Nii-san I love lots, entered my body through my nose and made this body, which had become Nii-san's only thing, hot.

From the depths of my heart, my woman's figure will end up having its appearance manifest.

"Nii-san, I love you."

Let's save up this twinge in my body until another time.

Ah~ Even so...... To be able to fall asleep wrapped in this scent, makes oh me the happiest right!

"......?"

Something, I felt an enormous sense of joy.

"Onii-sama? Chisome?"

Slowly raise your body up.

Onii-sama and Chisome are asleep as they were...... huh? If so, I wonder what that was just now.

At something I didn't really understand, I tilted my head and tried to hug Onii-sama's body once more.

"......Ehehe♪"

Today's me is great.

If it were the usual, I'd be half asleep and, with momentum, end up diving into Chisome's shadow, and yet, today, I am still able to be properly next to Onii-sama.

"......??"

But, the strange sensation won't go away.

Lately, a sensation that I don't really understand has been rushing about inside of me.

That is, when I look at Onii-sama, I feel a warmth in my chest area, and then I'd unintentionally end up reaching out my hand to him.

Chisome said that's what you want as a woman, but to me, I don't quite understand what that means.

“What you want as a woman......U~n?”

There is the sensation I don't understand, but I understand the meaning of the words, what you want as a woman.

That is, in other words, that means to be in the state of becoming one together with Chisome as before and overlapped bodies with Onii-sama, I guess.

"......-~~"

I've never thought of that kind of thing even once up until now.

But, now that I've ended up knowing that happiness, I can't forget that sensation anymore.

"......not with the becoming one together with Chisome, will Onii-sama also do it with me I wonder"

No matter how far I go, Chisome and I are connected.

That's why, no matter what form it takes, it doesn't change the fact that Chisome and I are loved by Onii-sama.

Even so...... Will Onii-sama give love to me my self, I wonder?

"It's a strange sensation. Just like a human...... Ah, it's no good. this kind of thinking is no good, I have to be confident that I am human."

I am not a monster; that's what Onii-sama and Chisome have told me.

A human being with just a little bit of special power, I have to think so.

If I were to remember a lot of things I don't know from now on, it's fine.

I am Mashiro...... I am not a monster, I am Mashiro...... Onii-sama's little sister, half of Chisome.

"That's right, you are not a monster that's why."

"Ah......"

When I suddenly heard that voice, I was relieved from the bottom of my heart......and then, I floated my body and moved so that it was sandwiched between Onii-sama and Chisome.

Chisome laughed as if troubled, but I was happy.

[Tl note: FYI, in the Mashiro POV part, she called Taiga at the halfway point "Nii-san" and not "Onii-sama." I don't know if this was intentional or if the author simply made a typo and just left it there for whatever reason, but for the sake of consistency, I followed it through with "Onii-sama."]
