Prologue

This is

I moved my neck slightly.

Dont ask why Im only moving my neck. Its because the rest of my body is bound tightly.

Dont ask me why Im tied up, I dont know. All I know is that Oyado is in the kitchen, happily making breakfast in a naked apron and with cat ear decorations on her head.

Thats right. Its been like this since I woke up. Its not because I have any special hobbies or anything.

It has to be because of the drugs that Ms. Mari developed. If I use the medicine to get some sleep then, until its effect time runs out, it is impossible for me to wake up.

And now Oyado has done this. Did she realize it after watching me for all this time? Being good at observing other people is an essential part of being an assassin after all.

But I didnt expect that she would go as far as this the day after we arrived at the academy.

I didnt notice it before, but now I can see that her emotional level has reached a terrifying 950 points!

Thats even higher than Aliyahs normal levelexactly what happened to cause this?

Even though Oyado looks really cute in the naked apron and cat ears Im not the sort of pervert who would lay a hand on his younger sister!

Even though she isnt actually my real sister.

But since she already calls me big brother I cant betray that relationship. It would be completely disrespectful!

It seems that youve woken up, big brother~

Oyado suddenly looked at me.

Just wait a little longer~ I wasted some time because I wanted to experiment with some new cooking techniques~

WellEven you wanted to eat breakfast with me was there any reason to tie me up?

Its because the information in my memories tells me that this sort of thing can make youths around big brothers age very happy.

Hey Hey Hey! What kind of information is that? Isnt it too much? Theyre corrupting children! Next time I meet the Smuus Im going to have to have a talk with them. This is too much, to have turned my sister into

Before I was finished, Oyado came up to me and gave me a twisted smile.

Even though youre saying that, your body is telling be all about your real desires~

I dont care where you got those terrible lines from, but could you take your eyes off of my groin? I think whats going on really isnt good.

Ahaha~ You arent qualified to say that to someone else, big brother. I can tell that your gaze hasnt moved away from me this entire time~

Well, its impossible. Im a normal guy. How should I say itit would be strange if I didnt react to it? Itd mean I was gay, right?

Im not intending to discriminate against homosexuals. Its just that I prefer the more popular option.

In addition, when I saw the two slight bulges at the top of her apron, speaking as a guy I have to admire myself for acting normally.

So thenif you dont release metheres no way I can eat breakfast

No, theres no way. No matter how tempting it is, I cant do something to my own sister!

Even I wouldnt be able to forgive myself if that happened!

Yes. Dont worry, Ill properly see that big brother is fed.

Oyado smiled and took a plate off of the table beside meit looks like it should be something like a sandwich.

Theres no way I can relaxThat thingshouldnt be a type of food that can be fed to someone?

Well~ I naturally have my own ways~

With a mysterious smile, she took the sandwich off of the plate.

She walked over to my side, slowly opened her mouth and bit down onto the sandwich.

Eh?

Had you wanted to eat it

I had just thought that when Oyado suddenly appeared in front of me and kissed me!

I was unable to react. Chewed bread, ham, egg and a young girls saliva poured into my mouth. My body felt like it was completely frozen.

Hahhah~

When she had finished pouring the food into my mouth, Oyado finally looked up and gasped for air.

Its reallytiring

If you feel its troublesome then just do it the normal way

Doesnt big brother like it?

Theres no correct answer to that sort of question

When this happens you can only keep quiet and look to the side, or the consequences would be too horrible to think about

Eh?

It looks like theres a name behind the wall over there?

When I take a closer lookthis is

Eh?

It looks like its Aliyah?

Theres no way to get out. I can only use the unique skill. I can see an omen of death being foretold in the stars!

What the hell are you two doing!

With a bang the wall on the side was broken down, and at the last second I tapped on the skill button.

Its been a long time

Flash Movement!

In the next moment I appeared in the mens bathroom on the first floor of the library. Thankfully I was bored and looked for it yesterday. I wouldnt have known where to go otherwise.

All right

I swallowed what remained of the sandwich and walked out of the library.

Now I just need to find somewhere quiet to eat breakfast
