Chapter 1

In a closed room or in the other word vacant classroom, there were two figures of boy and girl facing each other.

..... Damn, I have been done in. What a big mistake from the first day.

While he, who was full of complaints in his inner heart, somehow managed to suppress the urge to crouch down and hold his head, he watched out for her pretending to be quiet movement.

“Then, will you conclude an agreement”

She whom he doesn’t even know, said it with sound like a rolling bell that bashed down the space which was covered by silence.

TL's note : 静寂に包まれていた空間を打ち破るように鈴を転がすような声 -> This sentence frequently used to describe a girl with a very beautiful voice.

“….. agreement? “

After he heard her words, he sent her a doubt-like glance and revealed a distrust in his voice.

…..Aa, enough! Why it has become to this!?

“Yes. An agreement to mutually share secrets. For short, SHKK (SougoHimitsuKyouyuuKyoutei)

She said the details as she wore dignified expression.

He screamed in his inner heart as he saw such a girl.

As I said, how did it become to thisssssssssssss!?

The beginning of new life. Admission to Highschool.

That morning of entrance ceremony in when he would took a step closer the adulthood, he went mad in his room


“Dieeee! I dieeeee! No, rather than that, kill meeee! Someone please kill meeeee! “

The thing that the mad Souta’s hand hold is a crumpled article collection of middle school’s graduation that he just got yesterday.

The page that he read just now opened once again.

After he quietly closed it and thought for a moment, he went mad. This infinite loop thought  has already continued for 30 minutes.

“Embarrassing, embarrassing, embarrassing! Embarassingggg!”

On that page, something like this was written.

‘I will become a ruler of the world who manipulates people! Year 3 Class 2  Koda Souta

I know the art to manipulate people. From my point of view, you’re all as good as marionette. Highly ridiculous! I am the person who will rule the world by manipulating people to marionette—The person called the Legend Marionette Ruler.

That kind of thing was earnestly written and spelled.

“Uaaa!!What the hell is Legend Marionette Ruler!? In the first place, doesn’t Legend Marionette make no sense too much!? It’s too embarassingggg!”

While scratching his head, Souta writhed in agony on top of his bed.

“Wait Souta !What fuss you make this morning!? If you don’t quickly eat your breakfast, you will get late for the entrance ceremony! Here, be faster.”

 “I don’t want already! I don’t want to go to school! I don’t want to go to school-!

“Don’t talk such a foolish thing, hurry up and get ready! “

“…… Yes”

Unable to endure the pressure from his mother, Souta slowly crawled out from his bed.

Thus, the day of entrance ceremony opened the curtain of the beginning of Souta’s new life

◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆

Eight grader syndrome disease.

Middle school period. I was certainly having that disease.
　

The development was around the time seventh grade was over. I was in a bookstore near my house without having any purpose. That time, While I was aimlessly browsing through various books, there was a book’s title that caught my eyes.

‘150 way of psychology technique to manipulate people as desired’, on the book’s band, it was written ‘Forbidden for evil use! If you know your opponent’s heart, you can manipulate him as you desired!’

I was not especially interested, but somehow I picked it up and started reading it.

--And then I realized, I finished reading the author’s afterword, and ascertain that there is no next page.

I even surprised myself. But, I am more surprised when I saw my watch.
　

Because from the time I started reading it, about two hours already passed.

At the same time I saw my watch, I just realized the shopkeeper look at me with annoyance.

If I read it for 2 hours, I suppose it will bring an extreme annoyance to the store side.

I want to put the book I hold in my hand back on the shelf but since I didn’t have any extensive nerves, as it is, I headed  towards the cash desk.

“Hahaha. You have read it for a fairly long time, huh. How many times Oji-san has warned you?”

“Ee!? Really?”

“Aa. But as you was too concentrated, you maybe also entirely didn’t realize it. It will be 1050 yen.”

With bitter smile, The cashier smoothly hand out the slip and put the book in the bag.

“Sorry. I didn’t realize it.”

“After a long time, I haven’t seen a customer this absorbed in reading. Is this book really that interesting? Here’s your 50 yen change.”

“Yes. I won't do it again.”

“Then, that’s good.”

When I went out from the bookstore as I received the casher’s word, the neighborhood has become dark already.

“A... by the way, I am late for 1 hour “

As I said it, I started to dash to my home with full speed. In the midst of it, as I was afraid of the punishment for breaking the time limit, I really want to read the book quickly. The moment I realized it, the things that surprises me the most today was that my heart was racing to read the book again.

Thus, meeting this book was the start of me becoming a chuunibyou.


◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆

While he was reminiscing those things, he has arrived at the front of Ousaki Kouhou school’s gate which starting from today, he will go for 3 years.
　

Ousaki Kouhou, it was a good school name, but it was just an ordinary junior and senior school which stands on top of small hills.

From the gate to the entrance, there were a row of cherry blossom trees in full bloom. If you want to talk about the resolute characteristic of this school, it must be this tunnel of Cherry Blossom trees.

In the middle of many freshman walking in the sakura tunnel, Souta took out his glasses case from his bag, and put on his showy square-shaped glasses lens with inversed silver nylol frame.

This glasses that has been put on wasn’t for fashion. At the first place, Fake glasses wasn’t a known thing for others, this glasses were a thing that made after Souta pleaded to the employee of the glasses shop, “Please make a fake glasses which the others won’t find out that it’s a fake.”

◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆

Halo effect.  Souta was using this glasses for this psychological effect.

An easy explanation about halo effect, a cool man and a beauty girl – For example, Let’s say there was a girl with well-formed face and glossy long straight black hair.

What kind of personality is the character of that girl, each one of you please imagine it.


◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆

Have you finished imagining it?

Then, from my conclusion.

Don’t mostly people think that the girl’s personality inclined to the good one?

Why they thought like that? Because they misunderstand the essence thanks to the cognitive bias in her outer appearance

Next, Let’s take an example for boys.

Let’s say there is a cool boy (ikemen) with buzz-cut and muscular body with light brown skin as if sunburned.

What kind of personality does the boy may have?
　

Won’t you think he has a cheerful, refreshing personality, and likely to be good at sports ?

But, the reality maybe isn't like that.

The light brown skin actually is his real skin color and the buzz-cut was because it was just troublesome to change it. The face and the stature was good because of parentage.

Then, he maybe has a crooked mind and mean personality.

Do you understand it?　

This is the Halo effect’s bias that came from one’s mind because of the outward appearance.

Seita use this psychology effect, wore that glasses to manipulate someone’s impression about him.

In short, I will show them a serious and diligent personality.
