Hi, I'm Koki. A lot of things have happened since then, I'm already 15 years old. Too much time has passed?　No, I've discovered the fact that such a thing feels trivial!　I've been gathering information for 10 years, since I was about 5 years old, when I was rather able to act on my own volition. First of all, don't be surprised if the Japanese time on the third planet of our solar system, where I currently live, is.....

　It's January 4, 2102, 10:59 AM.

　I was born almost 90 years in the future, me, before the Japan I was living in and before I was reincarnated. That doesn't mean cars are flying and there's no such thing as personal teleportation technology. Some military power suits (I was so excited and excited when I first saw them on TV that I asked my mom if I was a robot?　Hey, is this a robot? (I've been asking a lot of questions about this) and at least some laser weapons that can be barely carried by individuals.
　But how can there be such a difference in civilization in just 90 years?　When I was alive in 2010, the progress of civilization had come to a halt to some extent. There was even a scholar who officially announced that it would only continue to decline slowly. I was about three years old, I think.　I had this question. So my mom and I were going through the library to pick out some picture books for the library, and I was secretly rummaging through the history books. I think my mom found out about it halfway through, but she thought I was interested in the pictures in the history books. She often keeps e-books with beautiful landscapes and castles on my personal device. That's very kind of you, My Mother!　I don't need much, but....


　Now, the details are different from the medieval period, but let's start with the places that are definitely off from the world I was in, in that order.

　1935 World War II broke out - The war started four years earlier than the historical facts, but it ended in a year and a half. The reason for this was that the United States, Russia, Germany, and Japan succeeded in building nuclear weapons at about the same time. Japan had attacked Pearl Harbor and occupied Hawaii in the early stages of the war, but bombers from the Aleutian Islands had put Japan within range of nuclear weapons. Although the war was a virtual defeat, the U.S. Army never landed in Japan on the condition that Japan would withdraw completely from Hawaii. In addition, national sovereignty and the vast majority of lives were protected because there was no unconditional surrender, even though the military was reduced and the constitution was redrafted. Of course, no nuclear weapons have been used against Japan. The nations of the world would use their abundance of national power and production capacity for technological advancement by avoiding a war that would have become bogged down in a quagmire with no clear winner in the end.

　In 1950, Apollo 3 successfully landed on the moon - mankind reached the moon more than 20 years earlier. By the way, 70 percent of commercial airplane companies use jet airliners in '48.

　1951 Cuban Missile Crisis - As in history, the United States and Russia came close to nuclear war, but the Pope was forced to resign, and a mood of war-weariness grew throughout the world, not just in the United States and Russia, and an all-out war was averted at the last minute.

　1970: World Security Treaty Conference - In an unhistorically unrelated incident, all nuclear-weapon states (including, of course, Japan) limit the number of nuclear weapons they can possess, referring to the Cuban crisis. All countries are limited to 23 weapons.

　1976 Tragedy in Europe - another not-so-historic event, an epidemic in the French countryside rages around the world; in 1976 the world's population of 9.1 billion had plummeted to 4.7 billion by the time the WHO declares the situation under control in 1984.

　1990: The Miracle at Versailles: The nations, exhausted by the tragedy in Europe, made a major decision. The permanent abandonment of all nuclear weapons and an 80 per cent reduction of all national military forces and the creation of a UN standing army. Many people say that this is a victory for peace, but many people also believe that it was the result of the conclusion of each country that the personnel in the national armed forces should be returned to the civilian population to restore the country's strength, if at all. By the way, the tragedy of Europe and the miracle of Versailles will definitely be on the test. I learned it too.

　Now, who's going to come out of the woodwork? You think I'm taking any kind of shit about something that's not related to me?　It's actually quite relevant!　Because it has to do with the textbook stuff I'm about to write about... Why? So can we skip ahead a little bit?

　Mother's Formula, 2091 (a formula that completely overturned quantum science published by Miki Arakawa in 1991) This world is only one of many time points. It is a mathematical formula that completely proves that there are other worlds at other time points. Miki Arakawa, who single-handedly constructed and published this frighteningly difficult equation, was called the "Mother of New Quantum Science" by the world.


Sorry ... that was based on my doodles!

　I couldn't help but smile, relieved to see Gongju growing up so well. Thinking back, he was a very strange child. He never cried at night, and he would call out to me immediately when his diaper was dirty. He seems to understand before I tell him that he shouldn't. He is very smart and very cute. I didn't have any parenting neurosis.
　Lately, Koki has been watching TV and newspapers a lot. It is impossible for him to understand what is on TV or what is written in the newspaper, but he has a serious expression on his face. His mature demeanor was so strange that he couldn't help but get into mischief. I took the remote control of the TV and switched it to the satellite Internet broadcast. Still, Kouki was looking at me with a happy glint in his eye, so I chuckled again and went to take in the laundry.

'Oh!'　Whoa!

　At that moment, I heard Conju's voice from the living room. A normally quiet kid screaming loudly! I took down the laundry and hurried to the living room, where I saw Gongju clapping his hands loudly as he watched the TV. He's not usually the kind of kid who reacts like this...
　Surprised, I turned to the TV screen and saw a new power suit on the news that was going to be deployed to the Ground Self-Defense Force this year.

'Oka-tah, oka-tah! Dare, dummy? A lo-o-o-o?

　At the same time as I was surprised, I felt that he was a boy, too. I still don't know what she's talking about, but I'm sure she's saying something about wanting you to buy her something.

"Ko-chan, you can't buy that thing at our house.

　When I said that, for some reason, Gongju had a delicate look on his face, but eventually he fell asleep. I gently lifted him up and carried him gently to the next room.








---- Early summer of 2090, Kouki Arakawa

　Oh no, oh no... What to do.... The mother in front of me has a devilish look on her face.


'Woooooooooo!　Oka-tah, scary, eeeeeeeeee.

　I was crying and wondering again why this had happened. It probably started about two months ago when I was taken to the library for the first time. In this day and age, most of the books in the library are now available as e-books. It's easy to imagine it's like choosing a DVD at a rental shop or something like that, but the only thing that wasn't available as an e-book was a history-related book.
　I was reading the book downstairs on the floor, but my mom was running towards me at a ridiculous speed and had a tremendously worried look on her face, telling me I shouldn't go away on my own. To tell the truth, I don't have to worry about it at all in these times, because I can tell where she is with my personal terminal and I need a nanochip for personal identification to get in and out of the library. Well, I can't talk about my feelings, so I apologize.

Oh, sorry.

Mom smiled gently and patted me on the head. Suddenly she found a history book in my hand, a book on the architecture of old castles, I think it was at the time, and asked me with her eyes if I had any questions.


(What?　You don't like this grimy castle?　Gross.... gross... gross, even for my child. And you're going to rent it? I'm the one who's going to have to carry this on my back to get home.


　I think that's what it's about. I don't see any smile in her eyes. When I turned my head down to think about giving up, my mother brought my book, which is as thick as a dictionary, to the counter along with the e-book I'd selected. I'm sure she thinks I'm being a creep, but she's kind. After that, she took me to the library every day. It became a routine for me to borrow the picture book of my choice and a book on history that I chose.
　One day, she chose a picture book, and among the books she had chosen was a simple math problem. It was so interesting that after I solved them all, I wrote the problems in my drawing book and solved them myself. And I was doing it again today until I was scolded by my mother, who has a devil's face, just now.........

　Well, is it time to go?　I've got to stop crying and find out why she's mad at me. I'm eating in this house and if I displease her, the worst thing that could happen is that she might leave me.... I quietly looked at my mom's face and saw her panicked and flustered. Seeing this as an opportunity, I hugged my mom and she gently patted me. But.........why was she so angry?


----Early Summer of 2090 Miki Arakawa Point of View

　Today I think I'm going to go to the library for the first time with Gongju. She's smart enough to be able to handle a quiet place like that. We walked slowly through the city, holding Gongju in our arms. When I was a child, gasoline-powered cars still ran, but now they are electric-powered cars. There is almost no chance of a traffic accident. Unless, of course, you run out into the roadway, but this kid wouldn't do anything so stupid.
　When we entered the library, I went to choose a picture book with Koki sitting on a chair. What kind of animals and stories does the child like?　I saw a Japanese wolf at the zoo on TV the other day and he was so excited that I thought I should make a story about a wolf.　Thinking about this, I suddenly realized that more than half an hour had passed. I rushed to the chair where he was supposed to be, but he wasn't there. I panicked.

'Don't worry, she can't go out without my identification chip yet.'

　I understand that in my head. But if I didn't say it out loud, I couldn't help myself with my anxiety. When I searched for the location of Koki's device on my personal wristwatch-type device that I usually wear, it was listed as F-2. There were only old paper books there, and there should be hardly any people there now.... No way!　A pervert?
　I ran to the place where Gongju was. But I soon found Gongju, and to my surprise, this kid was reading a book on fort architecture with a serious look on his face, covered in dust. I am sure that he would not understand it. Perhaps he was interested in the castle that happened to catch his eye. I decided to scold him for leaving on his own to hide my anxiety. I scolded him for disappearing on his own to hide my anxiety.

Oh, sorry.

　He apologized, looking like he was going to cry. In fact, it's not her fault, even though it's my fault for leaving such a small child alone for such a long time in the first place. Moreover, he scolded Gongju, who was quietly reading a book in the library. Probably this clever kid understood that too and apologized honestly, even understanding my feelings. That's why I couldn't speak to him, I just stroked him.
　Am I smiling well now? I looked into Gongju's face and he looked away. That's right, I didn't do anything wrong, but my mother got mad at me for it, maybe even teasing her a little. It's a good idea to take the book with you to the counter, as well as the book that showed interest to you, as you can't help but feel uncomfortable. It was the least I could do to make amends with him.


　When I was about to move him to the next room to take a nap, I saw a piece of paper in his hand. I knew that he had been working very hard to write something on his drawing book recently.
　But ... this ... this ... this ...




　I know what this is. And I understand that this is a hell of a lot of trouble if it's true.




So it's just a matter of ...











The Proof Formula of Quantum Science.








　I couldn't help but grab Gongju and ask him. What did you do with this?　Did you come up with that on your own?　Did someone tell you that?　Did it say that in the book?　Or was it on TV?　And Gongju cried as if he was frightened. I did it again, and although it wasn't his fault, I questioned him in a harsh tone of voice. I wondered what I should do, but Gong-Ju didn't stop crying, and this time I felt a vague fear that he would hate me completely. I was just looking around and wondering if he'd hate me completely, when he suddenly hugged me. As Gong-Ju buried his face in my chest, I regained my composure and gently patted him while Gong-Ju once again asked me what I did with this formula. And I had to do my best to hold back the panic again. The child cried out and said, "Boku ka-ta!


'Boku ka-ta!'

　I wrote it. That's how this little boy, my little boy, discovered the formula that scholars around the world are desperately searching for. Before I married Shuichi, I studied quantum science in a university lab, and that is how I was able to recognize this child's formula. It's no coincidence that such a young child discovered the formula. You can't derive this formula by accident. Probably, if this is made public, Gongju will be famous. But is that all there is to it?　Solving this difficult problem at such a young age is like a demon..........
　Thinking up to this point, he remembered the moment when Gongju was born. He remembered the eyes of that time, wasn't this child a normal child?　For a moment, the thought came to me and was replaced by fear. But I immediately remembered my vow from that time.




''Even if this world denies Gong-Ju, I will continue to protect him.



　Yes, I am a mother. I don't care if this child is the devil, still, Gongju is my only son. From then on, I acted fast, I wrote and published a paper as a formula that I constructed myself so that Gongju's formula could be leaked out. In the future, when this kid grows up, he might be angry that his feats were stolen from him. At that time, I'll be honest and apologize for being jealous of my son I'm sorry for being an ugly mother I'll apologize from the bottom of my heart. But I still want to protect Gongju.








If this boy is a demon I'm going to be a demon king.
