The self-cultivation of the passer-by hero

Although this happened suddenly, I would like to introduce myself.

My name is Kousaka Kyosuke. As you can see, it is an extremely ordinary name. By the way, my personal match with this name is almost over 90%.

At least that’s what I think. I haven’t participated in school club activities, and there’s nothing worth mentioning about my hobbies. Although I listen to pop music and read some novels and comics, I can’t say what my hobbies are. .

The Kosaka family has three children, and I am the most ordinary one.

Whether it is my sparkling younger sister who easily won the title of "School Idol" or my mysterious older brother who is no longer at home, they are not comparable to ordinary people like me.

Of course, it seems inappropriate to use the word mysterious to describe his brother, but that is no longer important.

Because just a few days ago, my brother had completely changed from "mysterious" to "mysteriously missing".

"Kosaka, let's read the third section of the text. Kosaka? Kosaka? Are you in a daze?"

"Huh? Ah, sorry!"

After being reminded by the classmates at the back table, Kyosuke came to his senses and hurriedly stood up and apologized to the teacher, but in the end he was scolded by him.

The teacher's question brought Kyosuke's thoughts back from their wandering thoughts, but only for a moment.

Sitting down again, Kyousuke found that he couldn't listen to today's class at all, because the recent events really made him forget about it.

That's about Kyousuke's older brother, Takeya Kosaka.

As mentioned before, Kyousuke has an older brother. In fact, when he was young, he liked this older brother very much, because at that time, the three brothers and sisters of the Kousaka family were all "ordinary people", including his younger sister.

When he was young, his elder brother Takeya had always been the object of Kyosuke's admiration, because although he had no obvious specialties, his only advantage seemed to be that he cared about his younger brothers and sisters, but it was this that made Kyosuke's impression of his brother almost perfect.

But things soon changed. The "excellent" eldest brother suddenly turned into a "troublesome" eldest brother. Before Kyosuke got used to this change, the eldest brother left home.

It was almost like a plot in a TV series. The eldest brother, who was dissatisfied with his parents' distrust, had a big fight with his family and eventually left home and even the city.

My brother moved to live with his aunt, who also lived alone, and even the school was transferred to the city where his aunt lived.

For a time, the eldest brother almost cut off all contact with the Kosaka family. Except for occasionally hearing his name on the phone from his mother and aunt, Kyousuke had almost no other contact with this eldest brother.

Everything changed for the Kosaka family when Kyousuke was completely unprepared.

First, the eldest brother "ran away from home", and then the younger sister changed. The originally good girl turned into a "school idol" with duplicity.

It all happened so suddenly that Kyousuke even thought it was a nightmare.

Then, the real nightmare began.

Regarding the eldest son's departure, Kyousuke's father, Kousaka Daisuke, although his words were always lukewarm and would sometimes scold him, he was also worried about him in his heart.

A few days ago, his father Daisuke took personal leave and went to the next city to meet his aunt on the grounds that "it has been too long since he has seen his sister." But that's what he said, but in fact everyone knew that he was going to meet his eldest brother Takeya. .

Originally, Kyousuke thought that the two of them might have another fight, or maybe they would have an awkward lunch with the mediation of their aunt.

In short, Kyosuke had no hope for his father's success in bringing his eldest brother back, but even so, he never thought that things would go far beyond his expectations.

The eldest brother is missing, and has been missing for half a month.

When they first heard the news from their father, both their mother Kano and Kyousuke and Kirino were shocked.

He would rather believe his father's cold joke, but Daisuke Kosaka's gloomy face dispelled Kyosuke's luck.

What happened was very simple. My father, who had not said hello in advance, came to his aunt's house, but got the news that Takeya was going on a "travel".

You know, although their father has a face that is more terrifying than a gang boss, he is actually a full-time criminal police officer.

Naturally, his father would not agree with such a casual excuse, and he believed that it was Takeya's excuse for not wanting to see him.

Perhaps this was also the idea of ​​my aunt, who wanted to induce her father to have such thoughts and make him return frustrated. However, no one expected that this time, his father's determination was a little too firm.

He pretended to leave, but took a detour to visit his eldest brother's school. Only then did he realize that his eldest brother had been on leave for more than half a month.

Even if it's travel, taking half a month off to travel during school time would be too free, right?

Sensing something was wrong, his father made many inquiries and finally determined a fact that shocked him, that is, Takasaka's eldest son, Takeshi Takasaka, had been missing for half a month.

Kyousuke didn't know much about what happened after that. He only remembered that his father's face when he returned home was angrier than ever before. That expression was almost the same as when his eldest brother ran away from home. No, it seemed that he was still angry. Be stronger.

"well."

Kyosuke let out an inexplicable sigh again. He looked down at his cell phone hidden under the table. On the call interface, there were a few scattered notes with the name "eldest brother".

Almost no one knew that he, the insignificant second son in the family, had the contact information of his eldest brother Takeya from the beginning, and that it was the other party who took the initiative to give it to him just for times like this.

The once close brotherly relationship has now become a single tree that needs to be maintained by the ridiculous reason of "preparing for father".

Since he couldn't even contact Takeya, it could only mean that the other party was not deliberately avoiding his father, but was really missing.

Kyousuke closed his eyes silently, and quietly put away his phone before the teacher noticed it, but at that moment, his phone suddenly vibrated.

at this time? Who could it be?

With some confusion, Kyosuke opened the closed screen again. The black and white word "Big Brother" on the incoming call notification made him stunned.

After being stunned for three or four seconds, he hastily put the phone into his pocket, stood up without thinking, and greeted the teacher.

"Teacher, I don't feel well, I have to go to the infirmary!"

With such a random excuse, and under the stunned eyes of the whole class, Kyousuke rushed out of the classroom, leaving behind the teacher whose expression was distorted with anger.
