Hearing the words of Kudo Ichiro, both Haruki Koike and Kato Yoshina came over to take a look.
A function question came into view.
Knowing that the function f(x) is an odd function, moreover on top of (－∞,＋∞) as an augmented function, if x, y fulfills the equation f(2x2－4x)＋f(y)＝0,
Then the largest value of 4x＋y is ____
The two that came over had confused expressions. They could understand the words, but when combined with the symbols together, they could not understand them anymore.
Haruki Koike said helplessly, "Ichiro, you should tell the truth to senior, we never even learned this in junior high. Our knowledge level would also be in the first year of junior high. This function is obviously a senior level question. How can we answer it if we can't even understand it?"
Kato Yoshina also nodded and advised, "You should stop doing this just to keep face. I heard that the last place of Class Three of freshman year was still at the elementary school level. Moreover, the senior in Sword Believers' Club also mentioned that there will be punishment for those who do not reach the average mark for the monthly test."
Kudo Ichiro wanted to retort, but he shrunk upon hearing about the punishment.
"The answer to this question is 8."
A voice like trickling spring water appeared beside them suddenly when the three of them were talking. Kudo Ichiro and the other two turned their heads and froze when they saw a mature and beautiful woman.
However, they all soon recovered. Sena Nagayama had an outstanding temperament, decent and elegant, causing students like them to feel restrained near her.
Looking at them, Sena Nagayama smiled gently, "Hello fellow classmates, may I ask you a few questions?"
The three of them nodded slightly after hesitating for a while.
Naturally, the question Sena Nagayama wanted to ask was about the Kinshin Lake. She initially thought that Kinshin Lake would develop into a holy ground for dating after so many years. She never would have expected to see a group of boys studying here.
The scenery here was great, and studying here would be very enjoyable. However, this was very different from what Sena Nagayama imagined! If her elder sister in Heaven knew about this, she wondered whether she would be glad or laugh or cry.
However, it was a good thing that the students in Sakura Kyu were capable of taking the initiative to learn. She thought that the school was full of delinquent students, she never expected to have this pleasant surprise upon entering the school.
With respect to Sena Nagayama's questions, Kudo Ichiro and the two answered truthfully.
The matter here was not a secret anyway.
Kinshin Lake was indeed a holy ground for dating before this. However, this place was discovered by a few Sword Believers' Club members, and they liked the scenery here. Every time during recess or the afternoon when classes were over, they all enjoyed studying here.
People who were dating there felt out of place upon seeing the members of Sword Believers' Club studying beside them. As time went on, this place became the exclusive place of the Sword Believers' Club.
From a holy ground for dating, Kinshin Lake became the holy ground for studying. Some ordinary students who liked to study would come even when there was no particular matter. The members of Sword Believers' Club who were passionate about studying did not look so scary after all. Moreover, when there was confusion in studying, they could question each other.
Some exceedingly smart students would eat here during recess while discussing academic matters. They would even answer the questions of the weaker students of Sword Believers' Club enthusiastically.
This was the situation at present. The entire Kinshin Lake was surrounded by students.
Sena Nagayama was shocked within her own thoughts. The Sword Believers' Club is too scary. Unexpectedly, one club can affect the whole school. Aren't there many delinquents in Sakura Kyu? There are so many people studying here. Will those delinquents not come to cause trouble?
If Sakura Kyu's delinquents knew that so many people were studying here, many would bring companions to collect protection fees.
When this question was posed by Sena Nagayama, Kudo Ichiro and the other two looked at Sena Nagayama with a weird stare. "Don't you know that the Sword Believers' Club is the biggest delinquent group in Sakura Kyu?"
"What?" Sena Nagayama was shocked. Delinquents studying together? Is this a joke? She started questioning her life.
Looking at Sena Nagayama's shocked expression, as if he knew what she was thinking, Kudo Ichiro fell into a bad mood suddenly. He immediately said, "The reason why Sakura Kyu Academy has such a good atmosphere is all due to the Head of Department, Kimura's contribution. Sword Believers' Club was established by him. If it weren't for him, I reckon that a protection fee would be collected from you once you enter the Academy's entrance."
Although he had been scolding Kazuki in his heart for the past few days, deep down, Kudo Ichiro knew that Kazuki was indeed doing this for everyone's benefit.
He was rebellious, but he was not st*pid.
Ever since he knew that most seniors of Sword Believers' Club got into their desired university, he was also determined to study appropriately. He also had these thoughts during junior high, but he did not persevere.
Now, he would be punished if he did not study properly. Also, with the encouragement and guidance from the seniors of Sword Believers' Club, he had a powerful motivation to study.
Kimura-san? It's probably Kazuki.
Sena Nagayama did not ask further because she could feel that the three students before her were starting to be unfriendly toward her.
Sena Nagayama roughly understood a little regarding Kazuki before coming to the Academy. She knew that he was Sakura Kyu's biggest delinquent and he had extreme deterrent power over all the schools in Jinwen District. As for Sword Believers' Club, she did not know that Sakura Kyu had such a group before she came here.
She actually did not want Kazuki to be Harunaka's home tutor before this because he was a delinquent. Who knew what perverse matter would he do?
But after seeing all this, she realized that she might have misunderstood him.
Sena Nagayama actually did not misunderstand anything. The news that she got was also correct. However, those were impressions of Kazuki from students of other schools.
Due to the restriction of entry and exit at will at the entrance of Sakura Kyu, students from other schools did not have the guts to come anymore. Therefore, it was only natural that they would not really understand what was going on in Sakura Kyu. The news that she got was also from a long time ago.
Just like Kudo Ichiro, before he entered the school, he thought that Sakura Kyu was still the concentration camp for delinquents. Only people like the Furuhashi sisters who lived near the Academy would understand the situation better.
When Kazuki first entered Sakura Kyu a year ago, the academy was indeed very brutal. Practically, anybody who angered him would end up being sent to the hospital because of him.
About half a year ago, he knew that allowing Kaito Kurokawa and the gang to play the game of 'Look at Who is the Luckier One' was risky. If this were exposed, it would inevitably cause opinions from the public to arise. It would be very likely to cause him to be thrown into prison, but he still did it.
That was because Kazuki knew that the recuperation of reiki would surely come. The recuperation of reiki would initially have a longer chaotic period, so he had no fear when there was something to fall back upon.
But as time passed, Kazuki became vigilant again very quickly. He realized that his thought was psychotic, and he was starting to go out of control. Another way to put it would be his views were beginning to become incorrect.
The nervousness from crossing over and the unaccustomed feeling in foreign land caused him to have a very inexplicable feeling. These feelings caused him to be very agitated and violent.
However, Kazuki was a Ph.D. candidate of Spiritual Academy after all. He saw way too many things during his time in the Spiritual Academy. Many lost the balance of their mindset and started to inflate after they gained strong abilities. They would lose control slowly after that and started becoming perverse.
When he felt that he had this kind of change, Kazuki became alert quickly. He started to guide his own mental issues consciously to enable his mentality to maintain a peaceful state.
He started to reorganize the Sword Believers' Club and provide the formulated study plan to Sword Believers' Club. He guided the members of Sword Believers' Club to the right path slowly. He was also studying with all seriousness in the process. He was influencing Sword Believers' Club through himself and was also influencing himself subtly.
He would still teach delinquents lessons and also advocate toward violence to simplify a complicated matter. But he no longer used force or caused someone to be sent to the hospital due to some petty issues.
Since Kazuki realized his own mentality issues, he used half a year to make adjustments and complete a round of mentality metamorphosis.
The scene at Kinshin Lake seen by Sena Nagayama was actually among the results of Kazuki's mentality metamorphosis. Yet, the most significant effect was the change in atmosphere at Sakura Kyu Academy.
When Kazuki changed himself, he also changed Sakura Kyu.
