The Stand in the Everyday World

"Isshiki, don't interrupt me first." Fujii Shunsuke held down Isshiki Caiyu's head and continued.

"The truly strong, like me, were not excluded, but you, Yukinoshita, who was socially weak, could only live a miserable school life, and then I, as a strong person, reached out to help you, so you, Yukinoshita, were also weak.

Because I have no friends, I deliberately ignore the importance of social skills and deny my own weakness in social skills. "

"But I was excluded because they were jealous—"

"Okay, stop trying to hypnotize yourself. There are examples of strong people who were not excluded. You may be very strong in other aspects, Yukinoshita, but you are a weakling in social situations. So don't make it difficult for Yui. Just let them join the club. Let her teach you how to make friends. Weak people can help each other and make progress together. Why should weak people be weak?"

"...So Fujii-san, you said all this just to help Yuigahama-san successfully join the club?"

Yukinoshita Yukino's eyes were cold without a trace of emotion.

185. Bug-like abilities

"Yukinoshita, don't be so sensitive. Face up to your own shortcomings and correct them. Isn't that what a strong person should do? The ancient sage of the Celestial Empire once said, 'When three people walk together, there must be one who can be my teacher.' Even Confucius often learned from others. Do you think you are more correct and powerful than Confucius, Yukinoshita?"

If someone knows nothing, they would naturally strongly refute what Fujii Shunsuke said. However, as a top student who can still compete for the first place in Sobu High School, Yukinoshita Yukino naturally would not dare to boast that she is more awesome than Confucius. Even if someone sincerely believes so, saying it out loud will only make everyone laugh.

Seeing Yukinoshita Yukino fall silent, Fujii Shunsuke gave Yuigahama Yui a look and continued, "So here you should admit your shortcomings and ask Yui for advice. The weak should not be complacent, but should take the initiative to improve. Isn't this your own point of view?"

Yuigahama Yui received Fujii Shunsuke's eyes, and her brain finally reached its limit in dealing with interpersonal relationships. She immediately stood up and hugged Yukinoshita Yukino intimately, with her face pressed against the cold steel plate: "Yes, Xiaoxue, let's be friends."

It was obvious that Yukinoshita Yukino was very uncomfortable with Yuigahama Yui's way of making friends, and she tried to move her body back: "So, Xiao, Xiaoxue, what kind of way of addressing is this?"

Yuigahama Yui refused to give in and continued to stick to her: "Xiaoxue is Xiaoxue, just like Xiaojun, this is how friends call each other!"

"Yes, is that so?"

Yukinoshita Yukino, who had never had any friends before, was frightened for a moment.

"That's it!"

Yuigahama Yui said with certainty.

Fujii Shunsuke also said at this time: "If you, Yukinoshita, really object to too many people joining the Service Club at once, then just let Yui join first, and Isshiki-san will wait until you think she is qualified before letting her join."

Giving a way out, Shunsuke Fujii sold Isshiki Iroha without hesitation without giving any points.

"Well... okay then."

Yukinoshita Yukino, who had already been shaken in her heart and had not yet agreed but was just holding on, faced Fujii Shunsuke's steps and immediately agreed by taking advantage of the opportunity.

"Wait! Senior, what about me? Am I rejected just like that?"

Isshiki Caiyu was dumbfounded.

"Just wait a little longer." Fujii Shunsuke said emotionlessly.

"why is it like this."

Looking at Isshiki Iroha who looked extremely disappointed, Yukinoshita Yukino asked, "Isshiki-san, so why do you insist on joining the Service Club? It seems to me that you are not actually interested in doing these things."

Isshi Caiyu answered immediately: "Of course it's to pursue my senior!"

"...Well, I reject your application."

Isshi Iroha started to act cute: "Yukinoshita-senpai, please be flexible. I will definitely help others in the future."

Yukinoshita Yukino was unmoved: "Isshiki-san, I'm also a girl, so your cute tactics won't work on me."

"I'm not pretending to be cute!"

"up to you."

Isaiha was filled with indignation, but Yukinoshita Yukino remained unmoved.

The two looked at each other for a while, and finally Isshiki Caiyu was defeated and stopped talking.

Fujii Shunsuke made the final decision: "Congratulations to Yuigahama Yui for joining the club!"

"Clap clap clap clap"

Yuigahama Yui started clapping violently by herself.

..........

After seeing off the indignant Isshiki Caiyu, Fujii Shunsuke took Yukinoshita Yukino to hold a simple small welcome ceremony for Yuigahama Yui, then left the school and took a car to Futaba Rio's home.

Today Eriri will continue to take Mashiro back. Shunsuke Fujii doesn't want to face the Shura Field right away, so he made up an excuse not to go home first. He will only go back after Eriri and Rita meet and communicate.

Rio Futaba's house is very big, and she lives alone. This is the norm in her family because her parents don't care about their daughter. They often quarrel and their relationship has been on the verge of divorce, so they often live separately outside.

"Fujii, why are you here?"

When she saw Shunsuke Fujii ringing the doorbell, Futaba Rio started to panic.

"Open the door first."

Fujii Shunsuke did not answer, but spoke directly to the screen.

"..."

Futaba Rio didn't ask any more questions and silently opened the security door of the floor.

"Fujii, yes, is there something wrong?"

Watching Fujii Shunsuke walk in, Futaba Rio moved the index fingers of both hands behind her back, but she still spoke calmly on the surface.

"Yes, because I need your help with something, Futaba. Or you could say I want to help you eliminate potential risks in advance."

Shunsuke Fujii put down his schoolbag and walked in front of Rio Futaba, looking at her carefully.

This time, he came to Futaba Rio's house, not only with the intention of completely conquering Futaba Rio, but also a big part of the reason was that Fujii Shunsuke wanted to see the Copenhagen Monster.

It's actually still early for Rio Futaba to get sick. It's only May now. If we want to wait until her puberty syndrome strikes and she splits into a new self, it will take at least until autumn.

Under normal circumstances, the protagonists who want to capture Futaba Rio will quietly wait until she becomes ill before taking action, but Fujii Shunsuke doesn't want to be so passive anymore.

As for Puberty Syndrome, it is the only supernatural factor in the [daily] world besides himself, and it is also a supernatural factor with very buggy strength and specifications of its abilities - whether it is Sakurajima Mai's Schrödinger's Demon, Futaba Rio's Copenhagen Demon, or Koga Tomoe's Laplace's Demon, these are all unreasonable bug-level abilities, so Shunsuke Fujii is naturally very concerned.

After all, this is related to one's position in this world.

But Sakurajima Mai's condition was too critical last time, and Fujii Shunsuke didn't dare to observe and experiment according to his own temperament, otherwise he might accidentally kill Mai, and he would have no place to cry, so he could only act hastily and pull Sakurajima Mai to the safety line first.

But there is no need to be so careful in the case of Futaba Rio. The Copenhagen Monster can split into new possible selves, which is naturally very troublesome for ordinary people in modern society, because there is only one person with an identity certificate. No matter how many people are split, only one person can have an identity, and the others are all illegal residents. This is a headache. In the original work, Futaba Rio's original body can only sleep in an Internet cafe.

But this has nothing to do with those in power. As long as Shunsuke Fujii wants, he can even ask Momobami Kirari to make new certificates and documents for 100 people, so that all the new Futaba Rios that are split out can become people in the sun, and the biggest side effect of the Copenhagen Demon will be solved.

And since there are no side effects, if conditions permit, Shunsuke Fujii naturally doesn't want to worry too much.

186.500 Futaba Rio

"My help? Help me eliminate hidden dangers?"

Futaba Rio couldn't understand the connection between them.

"Adolescence syndrome, Futaba, do you know?"

"Well, I remember reading this urban legend, which says that it is a supernatural phenomenon that may occur when adolescent boys and girls are in trouble... Is it true?"

As the daughter of a medical professor, Futaba Rio inherited her father's intelligence and reacted quickly.

"It's easy to explain now that you know. To put it simply, you are a patient of puberty syndrome, or a potential patient. If I don't take care of you, you will get 'sick' in about two to three months."

Hearing Shunsuke Fujii's conclusion, Futaba Rio did not rush to deny or disbelieve it like ordinary people would. Instead, she pushed her glasses and thought very calmly. After a while, she nodded.

"If the condition for the onset of puberty syndrome is adolescent boys and girls with serious psychological problems, then I am indeed a potential patient, but the prerequisite is that the disease of puberty syndrome exists."

"But since you said so, Fujii, then this disease must exist. I didn't expect that the urban legend is actually true. Is this some Academy City?"

She came to the conclusion very objectively that she had mental problems, and even complained about Fujii Shunsuke's hobbies at the end. Futaba Rio was terrifyingly calm. Maybe this is the world of strong people in science and engineering.

"I didn't expect you to believe it so soon, Futaba..."

"After all, it was you who said it, Fujii. So, is there anyone else who has this disease? What is my disease?"

"You are quite familiar with two of the other three patients, Sakuta and Xiaofeng, and the other one is Sakurajima Mai."

"The wound on that idiot's chest?"

"Yes, that's right, it's because of puberty syndrome."

Futaba Rio's face turned pale: "Then I won't be like this, right?"

Even though she was very self-conscious about her body, it was still her body after all, and she couldn't accept the sudden appearance of several large wounds on her breasts.

"You don't have to worry about that, because everyone's puberty syndrome is almost different. I currently name yours the Copenhagen Demon, and Sakurajima Mai's I name the Schrödinger Demon."

"Copenhagen's demon, Schrödinger's demon... Could it be that the essence of puberty syndrome is quantum mechanics?" Rio Futaba said in surprise.

"For now, yes."

Shunsuke Fujii explained in detail the adolescent syndrome that Mai Sakurajima suffered from.

"Because it doesn't want to be observed, even its own existence will disappear. Just like Schrödinger's cat, it is in a superposition state of life and death. But if it refuses to be observed, even its actual existence cannot be confirmed. Is this the power of Schrödinger's demon?" Rio Futaba pondered.

"But the Copenhagen demon... the Copenhagen interpretation? But this is also based on the observer theory. Is there any difference between my illness and Mai Sakurajima's?"

"Emmmm, from the performance point of view, there will be many differences. Mai Sakurajima refused to be observed so her existence disappeared. As for you, Futaba, a new you will be separated based on your consciousness. The personality and consciousness may be a little different, but they are all you, or should I say different possibilities of you?"

As he spoke, Fujii Shunsuke's tone became a little erratic. He realized that he was a little anxious to name Futaba Rio's illness the Copenhagen Demon so quickly.

"Two me? In this case, the observer theory is not applicable. Instead, it has a flavor of the many-world interpretation. When observing, it does not cause collapse but splitting. However, it is not the whole world that is splitting, but myself. That is why two of me can exist at the same time. In this case, it seems more reasonable to name it the Many-Worlds Demon. Why did you, Fujii, name it the Copenhagen Demon?"

Schrödinger's cat experiment was originally proposed by Schrödinger to support Einstein and oppose the Copenhagen school's interpretation of quantum mechanics. Schrödinger thought it was impossible for a cat to be neither alive nor dead. In the end, it was used as one of the supporting arguments, just like Einstein.......

The multiverse interpretation explains Schrödinger's cat and holds that the wave function never collapses, that is, the cat is not neither alive nor dead, but at the moment of observation, the universe becomes two, one universe cat is alive, and the other universe cat is dead. In simple terms, it is the parallel world theory, and Copenhagen does not recognize this interpretation.

And because puberty syndrome affects the individual completely, when the observer Rio Futaba's consciousness was divided into several parts, she herself became two people, one of whom was her original self, and the other was the person she imagined she wanted to be.

So in general, after Fujii Shunsuke explained in detail what would happen when his puberty syndrome struck in the future, Futaba Rio thought it was relatively more appropriate to call herself a multi-world demon.

Facing Futaba Rio's unconscious questioning, Fujii Shunsuke remained expressionless and said with a face-saving attitude:

"Because the Many Worlds Monster is completely meaningless and sounds a bit corny. In comparison, the Copenhagen Monster is much cooler."

As for what he said to Yukinoshita Yukino not long ago, "A strong person must face up to his own shortcomings!"...what was that?

"Oh, okay." Futaba Rio agreed without any objection.

"But, Futaba, remember this, although we are still called the Copenhagen Demon, you cannot be limited by this name. You have to work hard on the multi-world interpretation, so that I can see two or even more of you at the same time, instead of only being able to observe one at a time. Can you do it?"

Shunsuke Fujii had a serious expression.

If multiple Futaba Rio cannot coexist in front of an observer, then the Copenhagen Demon can only play an important role for Futaba Rio herself. For example, No. 1 is responsible for studying, No. 2 is responsible for doing experiments, No. 3 plays video games, No. 4 is in love, No. 5 works to make money, and so on. If one person is split up and used as several people, and then combined into one, all of Futaba Rio's experiences and memories can be shared, allowing her to develop into an all-rounder. But this means little to Fujii Shunsuke!

Anyway, I can solve all the side effects. Even if ten Futaba Rios appear in the same place at the same time, I can provide evidence to prove that they are the unprecedented decuplets. So it is better for them to exist at the same time!

Imagine a lovely girl with all the personality traits from the three-nothing to the eccentric, from the inferiority complex to the little devil, and then serve you together... Do you think of that scene? Even twin sisters have the ancient characters of Ehuang and Nvying, and ten triplets or even more... Please imagine it yourself.

ps: Today's chapter really killed me. Quantum mechanics is so confusing. The main reason is that Rio Futaba's puberty syndrome is a bit like a bat. It has both the Copenhagen interpretation and the many-worlds interpretation, but the many-worlds interpretation applies to Rio Futaba. In the original work, the two Rio Futaba have never tried to meet each other. She can only guess and cannot make a statement, so she can't be sure.

But I didn't think too much about it yesterday, and I identified Futaba Rio as the Copenhagen demon, because it sounds better and catchier, and it doesn't go wrong when put together with Schrödinger's demon, Laplace's demon, and Maxwell's demon. Unlike the many-worlds demon, the previous ones were all names, so how come you are a noun? But now I think it doesn't seem right, but I can't put it into words.

So there is no other way. The protagonist also said that this name was chosen just to sound good, so if there are experts in this field, please ignore my little idiot in the medical field.

ps2: It took too long to look up the relevant information and interpretations. I was stunned. It took me more than three hours to write this chapter. My brain cells were seriously damaged, so I will update it today.

187. Be my girlfriend!

As for whether it can be done...after all, adolescent syndrome is caused by the psychology of adolescent boys and girls. Whether it is Schrödinger's demon that can eliminate its own existence, or Laplace's demon that can predict the future of an entire summer vacation until he finds the most acceptable result, they are all caused by their own psychology.

Then under deliberate guidance, one would expect more different selves to exist at the same time, rather than expecting a better self to replace one's own existence. It is not impossible for Rio Futaba to do what Shunsuke Fujii said, or it is very likely. This is the outrageousness of adolescent syndrome.

Although she didn't quite understand why Fujii Shunsuke said that, Futaba Rio nodded immediately, and then she showed a surprised expression: "Fujii, do you mean that instead of preventing puberty syndrome, you want to accelerate its occurrence?"

Futaba Rio remembered that Fujii Shunsuke said at the beginning that he wanted to "help himself" and "eliminate hidden dangers". Did she hear it wrong?

Fujii Shunsuke looked at Futaba Rio with a strange look, and then said in a matter-of-fact tone: "This is a superpower, Futaba, haven't you ever thought about getting superpowers yourself one day? Now that you have the opportunity, why do you give up and stop it?"

"And when I say eliminate the hidden danger, I mean to eliminate the danger that if there are multiple of you, only one person will dare to live an upright life, and the others will have to hide from this hidden danger. I don't mean to help you eliminate the adolescent syndrome."

"But, suffering from puberty syndrome means that I actually have psychological problems, right? In this case, don't I need treatment?"

Futaba Rio has always known that she actually has some psychological problems, but knowing is one thing and whether to deal with it is another. If Fujii Shunsuke wants it, she will try her best, but now... not stopping it means letting nature take its course or even adding fuel to the fire?

"Futaba, do you think people like you with mental problems are the majority or minority in this world?" Fujii Shunsuke suddenly asked an irrelevant question.

"Since he has a mental problem..." Futaba Rio was a little unsure, "Then he should be a minority, right?"
