Chapter 1 My name is Kyosuke Takahata, but I don't want to be pushed by my sister

I want to see my sister, if I can't find it, then write it myself...

If you like it, write more, such as being the elder brother of the black cat, and then, for example, becoming the elder brother of Ayase Aragaki...

If you don't like it, then write less, anyway, I just want to successfully experience a sister control in spirit.

Text below.

……

"a."

Hearing the shouting behind him, Kesuke Kosaka couldn't help but secretly thought in his heart: This is really a bad name.

The reason why he thinks this name is bad is entirely because he is not the owner of this body, but a traveler from other worlds, who clearly knows what this name means, has a lovely sister, and has successfully attacked himself. younger sister……

Isn't incest or something bad?

She's cute, but she's a real sister!A sister who is related to her father and mother by blood...

He turned around and followed the voice, calling out that he was his mother in this life.

Kasaka Kano.

Although he has been in this world for several months, he doesn't feel anything about this mother at all. If his body is not used to calling the other's mother, he doesn't even have the idea of ​​calling the other's mother.

"what happened?"

If he can call his mother less, he tries to call as little as possible, even if it is rude.

As for whether you will reveal your identity?

What are you kidding? His body is a genuine Kosaka Kyosuke, even if he does a paternity test, he has no fear.

And he doesn't care about this identity.

"You forgot to bring your lunch."

"Oh."

Kosaka Kyosuke took over the bento from Kano Kosaka, and he didn't have any complicated feelings in his heart. He had been used to this situation for a few months. Although he preferred to eat the special bread in the cafeteria compared to the bento, it was not Kosaka's Cano's food is unpalatable and it's not something she's resisting.

It's just that the specialty bread is more palatable.

On the way to school, Kosaka Kyosuke absentmindedly looked at the surrounding scenery, thinking about how to move out of the house.

Obviously he is the eldest son, but his family status is too low, and there is no privacy at all.

A few times when he was reading the yellow book to release his physical and mental stress, Kasaka Kano, who was almost intruded, found out... If he continued to be so frightened, he was very worried that he would not lift it up, and if the little yellow book he bought was not hidden, he would always be caught. If it is burned down, it will also be criticized in front of the family.

This kind of life without status at all made him feel very bad and tired.

He would have moved out long ago if he hadn't been able to find a job and couldn't afford the rent.

When he came to the school and listened to the teacher in the lecture hall talking about the knowledge that he didn't understand, Kesuke Kosaka nodded in agreement from time to time, but in fact he didn't understand a word.

He has inherited the knowledge stock of Kosaka Kyosuke, but it has not been fully digested.

As for previous education?

He felt Alexander when he graduated from elementary school.

When he got home from school, Keisuke Kosaka digested the knowledge in his brain.

He knows how difficult it is to step into the society without an education. Naturally, he can't go on like this. A lot of knowledge is often forgotten when he doesn't need it, but the knowledge that he needs to use in many parts of his homework involves those knowledge. Can revisit.

In the school he attended, homework not many others could complete in half an hour, but he took more than two hours.

A lot of the time, they are looking up information to supplement their knowledge gaps.

If he really can't figure it out, he will turn to his childhood sweetheart, Asami Tamura, with this body.

He doesn't hate this childhood sweetheart.

After several contacts, she has even been regarded as one of the reference objects for marriage, well, it is actually the only option.Even if he knows all the future plots, he still does not have the confidence to attack Kosaka Kirino like Kosaka Kyosuke in the original novel, and at the same time he can attack most of his sister's friends.

After all, he is not the real Kosaka Kyosuke!

During the period, Kasaka Kano made several surprise attacks, and a trace of suspicion flashed in the eyes of Kasaka Kyosuke, who was watching the study.

This kind of distrust and suspicion made Kesuke Kosaka very hurt.

...I'm almost eighteen years old!

Even at this age, it is normal to watch Huang Shu release physical and mental stress after returning home from school!

If I want to give my ancestral genes to Takasaka Kirino, it's okay for you to guard me like this, but I don't think about it at all, you're going too far...
