"......Mashiro, go on and back to Chisome's side."

"Muu......no good?"

"Well, even if you do this, no one finds out, but still......"

After going to school together with Chisome was over, because the class was naturally different in the first and second years, I separated from her. But for some reason only Mashiro, who could be said to be the other half of Chisome, remained attached as it is to me.

Chisome, while laughing, was waving her hands at us, but for me, I'm greatly at a loss as to what to do in this case.

"It was the best scene since the morning, Rikudou-san. A~h, it's the best~...... even if it's cut it won't cut, a strong ties of mutual love between brother and sister...... This is progressing good!"

"......I'll make it be not to ask what is progressing good."

"Ona――"

"Shut up!!" (in a japanese english)

Is this girl already no good I don't know it anymore.

I left Chisome, resulting in me coming and entering the classroom with Misora. But it seems that a bunch of boys, were they misunderstanding something, are thinking that there was something between me and Misora.

Even though it's already standing out because of the thing with Chisome...... I let out a small sigh.

(Is there something with Misora? It's true that we might be on good terms, but this be breaking you guys fantasies into pieces right, look at this face)

As if to ruin a beautiful face, at this face that seems to be drooling at any moment, this face seriously, by looking at it even a 100-year love will grow cold.

"......This human is interesting"

"You better stop, Mashiro, that alone I won't let"

Look, it'd get Mashiro ended up becoming interested didn't it.

"Earlier, Chisome did say she was scared, but that's kind of a joke thing, you know. That girl, she is quite curious about this person."

"Seriously!?"

"Un. How should I put it...... Because this human truly wishes for the relationship between Onii-sama and us from the bottom of her heart. I think it's because Chisome is having the conviction that this human will never be a minus for us."

"......I see"

That does sound Chisome-like, or rather, basically, that girl doesn't trust anyone other than me, but I guess she can recognize someone like Misora, who from her heart is blessing her, as an ally.

Well, I question if I should be congratulating on this, but...... or rather, I was taken aback by the fact that I was having a normal conversation with Mashiro in front of Misora just now.

"......Shindou?"

"What is it?"

Misora, who has been staring at me the whole time, just smiled...... Could it be that she is seeing Mashiro's existence? Me looking at Mashiro casually, she shook her head to the side, so unmistakably Misora was not seeing her.

"It's fine, Rikudou-san."

"......What about?"

"Me, I can't see anything, but I can feel it. Of what Rikudou-san had beside him, something similar to Chisome-san's wave motion. I see that this is exactly the ultimate form of brother and sister isn't it!"

"..............."

"Un. After all it's interesting." (Mashiro)

It's scary for me you know.

"Ossu Taiga!" (Shinji)

"Morning to you!" (Kouki)

"O~ Morning, both of you." (Taiga)

"Good morning" (Shindou)

"......Morning" (Mashiro)

Mashiro......you.......!

There's that greetings are a basic and normal thing for a person to do; however, I felt kind of moved by Mashiro doing that.

Even though that voice was not heard or recognized by anyone...... Even so, how adorable Mashiro was when she shyly said morning.

"For some reason Taiga is coming be to cry, look."

“This guy is easily moved to tears these days, you know?”

"To make fun won't do you know, you little good-for-nothing fools." (Shindou)

Like I said, that's why I can't stop Misora's character from collapsing.

Well, she has certainly become easier to talk to than the original work, so if I think it's a good change, it's not something to always make bad of.

"It looks like Onii-sama's friends are all here anyway, I'm going back. See you later with Chisome together okay."

“A-, aah......give Chisome my regards.”

"Un"

Mashiro separated from me and her figure disappeared as if she had sunk deeply into the ground, as it is.

Certainly, hierarchically, Chisome's classroom will be below this, but the way she disappeared just now was lightly horror, so I had to have myself tell Mashiro so that she'd refrain from doing it again as much as possible, or things can't go.

"Even so, Taiga, it became a lot of rumour, you know?"

"Was it the thing about Chisome?"

"Right right. They seem to be curious about what kind of relationship you two have, but it seems that there are many who felt relieved the moment they found out you were brother and sister."

"Fu~n"

Well, certainly, even if the bunch of people who aren't that close to me know that I and Chisome are brother and sister, they shouldn't know that it's an in-law.

As Kouki said, guys who were relieved by that, in other words, it means that they at least have feelings towards Chisome......"It's useless, so give up," along with a slight sense of superiority, I'll be given troublesome things to happen, I think.

"Well, if something happens, I'll tell you?" (Shinji)

"There is a fellowship with both Taiga and Chisome-chan. I can come rely on you right?" (Kouki) [Tl note no 1]

"Of course, please count on me too, okay?" (Shindou)

"...... Hahaa, I got it. If something happens, let me rely on you all." (Taiga)

I am truly blessed with good friends.

After that, the teacher came and the morning assembly started, but there things came to be that my classmates, including myself, got to hear something we are curious about.

"Two days from now, it will become the day after tomorrow though, a transfer student will come to the next class. Used to live in a foreign country, but when comes back to Japan this time, will transfer to this school."

"Boy? Girl?"

"It's a girl."

"Is she cute~?"

"Dunno. Go see for yourself."

A story about a transfer student who suddenly came to attention, but for me, it wasn't particularly all that sudden.

(......with this, finally huh)

I thought that perhaps it wouldn't be the same as the game, that there was also a pattern where the transfer student wouldn't come, but that was not the case.

It was also a hit that it's a girl, so I'm already nearing conviction, but even so, there's also not non-existent the possibility of a completely different person......well, everything will become until the day after tomorrow.

“For now, Shall I do my best today.”

Perhaps because there was also the fact that Chisome was in the same school as me, was my body tightened, I was able to concentrate much more than usual.

I could feel Mashiro's stares from time to time; it could be that, she might be, was somehow separated from Chisome and was looking at me.

Like that and this, time passed quickly and it became lunch break, and me with Shinji and Kouki, stuck our desks close and had lunch together.

"Come to think of it"

"What?"

“Taiga’s bento is made by Chisome-chan, right?”

"Yeah"

“Are the contents and so on all the same?”

"The amount is different, but it's the same."

If it's Chisome, she's capable of anything, but as expected, to go out of the way to make two kinds of bento would be tough for her right.

“It looks delicious every time I look at it after all, eh; I so envy you.”

"It's extremely good you know. Wanna eat some tamagoyaki?"

“Is that fine!?”

"Here"

I gave them each two tamagoyaki.

Although I've been associated with them for a long time, if I think about it carefully, they've never eaten Chisome's homemade food before......Now then, I wonder what kind of reaction they'll give and show.

"Amuu"

"......!"

The moment they put the tamagoyaki in their mouths, both suddenly opened their eyes wide.

"......good-"

"Too......delicious"

"Right? Chisome's dishes are really delicious that's why."

Of course, not only bento but also everyday dishes; she has them served and offered with the best execution.

When I see my little sister's figure like that, there are a lot of times when I think I also want to cook, but she says that the kitchen is my battlefield and Chisome won't let me cook, riight~.

"......I always want to cook for Nii-san. On that alone I can't give it up......I'm sorry for being selfish, Nii-san."

That was the too cute Chisome's selfishness.

Well, even with that said, there are also times when we cook together anyway, and when Chisome rarely overslept, I'd be the one to make breakfast as well, but of course, comparing it with Chisome I was overwhelmingly defeated.

"Really, make sure you cherish her alright, of Chisome-chan."

"I know. I don't think it will come to this, but if I neglected Chisome, please kill me."

"Got it. I'll kill you as hard as I can."

"......at least go at it easy on me."

Wonder if it will be okay, with these friends of mine......。

After that, time passed and it became after school, and I had promised to meet Chisome at the school gate, so I headed straight ahead like so...... But.

There was an event happening that occurred precisely because of a beauty like her.

"Rikudou-san! Wonder if you could give me a moment?"

"I don't have such time. From here, I have an important promise to make."

"Somehow, I beg you!"

Whose waiting earlier was Chisome, but was caught by a boy whom I think is a classmate.

Guessing from Chisome's expression, I can tell that she's feeling quite somewhat irritated anyway, and that boy also seems to be quite persistent and strongly smells of trouble.

"Chisome!"

"a, Nii-san!"

But, however, I didn't want to make Chisome look even slightly displeased, so I immediately called out to her.

The moment she saw me coming, as if she had forgotten the existence of the boy in front of her, she ran up to me and, as it were, embraced me.

“I’ve been waiting you know, Nii-san. See, I have some shopping to do today that's why, let's go soon♪"

"Got it...... For the time being, it's fine to leave it alone, right?"

"It's fine. I don't care anyway."

"-......"

"I don't care," the boy classmate looking like frustrated bit his lip when she said that.

And, or should I say, as expected, he severely sharpened his gaze and glared at me......that, as a matter of course, touched Chisome's and Mashiro's imperial wrath.

"Mashiro, go on do it"

"Understood"

No way are you going to eat him? I thought of such a dangerous thing, but it seems Mashiro decided to go at it with a method that would make her figure become invisible.

She went around behind the boy and put her hand on his trouser and pulled them down as hard as she could.

I guess it's her mercy that she didn't lower his underpants; nevertheless, at this moment, he suddenly became a boy who lowered his trouser at the school gate.

"......e?" (Boy)

For the time being, with amen in my heart, I put my hands together.
