My daily life in various anime crossovers can't possibly be this sci-fi.

My Daily Life in Anime Crossovers Can't Be This Sci-Fi Author: Dr. Kostein

Synopsis: This is a world where the "abnormal" has gradually become the "normal":

At school, you can learn a wide range of spells and reality distortion techniques with broad applications. For just a few thousand dollars, you can take a trip across timelines like your favorite online novel protagonist. There really are idols in the world who can kill a triceratops with a single punch, and you'll never guess how many meters in diameter the blonde girl at the next table who likes to draw in her notebooks can conjure up.

In this era where the Holy Grail War is about to be adopted as an Olympic event, high-risk time travelers must register their household registration, and even cultivating immortality requires registration with the relevant authorities for stage-by-stage professional title evaluation...

...I just want to be an ordinary person in an extraordinary way.

Chapter 1, Section 1: This is an era where even time travel requires identification.

About half a year has passed since Jiang Jinghua transmigrated to this strange two-dimensional world. Even now, he still feels a little scared and grateful for his quick thinking and good fortune when he first arrived.

When he woke up to find himself facing an unfamiliar ceiling, he immediately realized he might have transmigrated and began to calmly and cautiously deal with the memories that were suddenly flooding his mind. From these memories, Jiang Jinghua learned the basic situation of the person he possessed: his parents had both died in an accident, and as an only child of high school age, he now lived a wealthy and independent life relying on his parents' insurance money. Although he didn't have a younger sister, this situation perfectly fit the typical slice-of-life male protagonist trope... except for one thing.

In fact, Jiang Jinghua's parents died during a cross-dimensional police operation. The vertical takeoff and landing transport plane they were on was blasted into dust by a Nascent Soul cultivator's natal magic weapon.

Yes, I'm not joking; this is truly the real cause of death for Jiang Jinghua's parents. Therefore, to honor Jiang Jinghua's parents for sacrificing their lives for human civilization, their employer, the globally renowned interdimensional development organization, The Searching-Containment-Production Foundation, provided Jiang Jinghua, who lost both parents, with substantial financial support.

Although Jiang Jinghua had lost a large amount of his memories of anime characters from his previous life, when he saw people everywhere dressed like characters from light novel covers, he immediately realized he had transmigrated into the legendary two-dimensional world. However, this two-dimensional world was quite unusual: because "transmigration" was as commonplace as "business trips"!

This is a terrifying world teeming with magicians, cultivators, humanoid mechs and spaceships, fantastical species, and a zombie virus. The reason human civilization in this world can simultaneously develop so many astonishing technologies across such a diverse range of fields is entirely because it has reached the point where "nations dominate world travel." The plot of "traveling to another world with one's nation," a common trope in online novels from my previous life, has become a reality in this world!

What? You're saying you've been transported to the Type-Moon universe to fight in the Fourth Shinobi World War? The number of Kiritsugu Emiya clones currently working at the United Nations has already exceeded three digits! And the Foundation has even established a Mobile Task Force entirely composed of Artoria Pendragons from various parallel worlds!

What? You say you've been transported to the Re:Zero world to learn magic? The number of dragon-owning kingdoms that have successfully established diplomatic relations with the United Nations has now exceeded twenty!

What? You're saying you found a system on the street or became a reincarnator? The number of such people locked up in the Foundation's containment facilities already exceeds five figures!

Although Jiang Jinghua was a transmigrator, he had absolutely no cheat codes. He was initially somewhat dissatisfied with this, but now, thinking about it, he practically wanted to burn incense and thank the gods for protecting him from having any cheat codes! After being subjected to containment procedures, whether you're a plagiarist, an ACG master, or a harem guy who'd die if he didn't conquer girls, none of that matters anymore, right?

Without any special abilities, Jiang Jinghua, a transmigrator, began his peaceful and friendly daily life in the new world. Currently, the St. Christina International Academy, where Jiang Jinghua attends, is a special institution approved by the United Nations' Extraterrestrial Affairs Committee and funded by a foundation. It specifically recruits outstanding students with talents in consciousness mechanics (the term for magic in Earth sciences) and handling interdimensional affairs. Of course, as a cover, it also recruits ordinary students from the general public.

Although he attended such a school, Jiang Jinghua's daily life was actually quite similar to his previous life, except that he had many more subjects. This time travel didn't give him any cheat codes (except for a little bit of common-level magical talent), so Jiang Jinghua, who had no special talents since his previous life and whose only three hobbies were watching anime, playing games, and writing for fun, didn't embark on the path of building a harem like a typical male protagonist.

Six months have passed, and in these six months, Jiang Jinghua's life has been as stable and uneventful as in his previous life. Although, according to the special edition of the news broadcasts provided by insiders, the Holy Grail War is fought almost every day, magical research occasionally yields small breakthroughs, at least one cultivator fails to transcend tribulation every month on average, and major events such as alien invasions and nuclear wars occasionally erupt in hundreds of parallel worlds, the main world under the Foundation's governance remains peaceful as always. Jiang Jinghua's mentality has gradually changed from initial surprise and excitement to a state of complete indifference and a lack of desire to laugh.

Many of the unusual events happening in this world are actually quite similar to the news from my previous life. No matter how chaotic the situation in the Middle East is, schools in China still have to hold classes and submit assignments.

And Tokyo in this alternate world is no different: when the cherry blossoms in Ueno are in full bloom, they do indeed resemble light, crimson clouds; but now it's September, and perhaps only genetically modified cherry blossoms can bloom at this time of year. There's really nothing noteworthy about Tokyo right now: no Holy Grail War, no mutated lizards dozens of meters tall, no underground fortress cities, and no blood-red seawater—everything is just like a normal metropolis.

In this extraordinary yet ordinary world, Jiang Jinghua remains an ordinary person.

It's already Sunday afternoon, and I have to go back to school tomorrow. If I don't finish the summoning spells course tonight, which I've been putting off since Saturday...

Jiang Jinghua stood up from the chair, got dressed, and left home.

The first things to buy are magical paper for transcribing the scrolls, and three different magical potions. Jiang Jinghua is heading to... nowhere else but a convenience store.

Jiang Jinghua stopped in front of a 7-Eleven convenience store. After using a simple precognitive spell to confirm a circular shield-shaped symbol near the doorknob, he pushed open the door and went inside.

The circular shield-shaped logo is the symbol of the well-known Search, Containment and Production Foundation (3S Foundation, or sometimes simply SCP Foundation).

"Hello! What can I do for you?" the cashier at the counter asked as Jiang Jinghua entered.

"Please take me to the inner district," Jiang Jinghua said.

The "Liqu" district, as the name suggests, is a place that sells certain special goods... not that kind of special goods.

Go down one floor through a stairwell behind a mysterious iron door with a sign that reads "Authorized Personnel Only" to reach the so-called inner area, which is the area where magical items are sold.

Section 2, Chapter 2: The School Idol Who Works Part-Time

The interior and exterior sections are not much different in style, both featuring numerous shelves densely packed with goods. The various items are categorized by use and material, with each shelf labeled accordingly, giving the impression of a library.

Thanks to the shop owner's thoughtful arrangement, Jiang Jinghua easily selected all the items he needed to buy and arrived at the cashier.

"Hello, could you please pack these things up... Huh? Aren't you the same one from last time..." Jiang Jinghua was surprised to find that he had run into an acquaintance.

"Ah! That's right!" the cashier said happily, "You must be Jiang Jinghua from last time!"

The cashier standing in front of Jiang Jinghua was an exceptionally beautiful young woman. Even wrapped in a plain convenience store uniform, the beauty of her well-proportioned figure remained unaffected. She looked no more than sixteen years old, with a round face chubby with a touch of baby fat, and fair, firm, and elastic skin that made one want to pinch it.

She wasn't the kind of woman who was "perfect in every way," as often described in novels. In fact, there were some minor, subtle flaws in the details of her features. However, these flaws did not detract from her beauty; on the contrary, they complemented her lively personality and added to her overall aesthetic appeal.

She had short, bright orange-red hair, reminiscent of the color of the rising sun. Her hair on the right side was tied into a neat side ponytail with a pale yellow ribbon, giving her an impression of boundless energy.

Jiang Jinghua remembered who she was. He had met this girl named Honoka Kousaka on a spellcaster forum last month. They had been arguing online about which type of Evocation spell scroll could cause a larger explosion, and somehow Honoka had become interested in him, exchanging contact information. At the time, Jiang Jinghua assumed she was a student specializing in Evocation magic, but he later discovered that she actually majored in Illusion and had already obtained a fourth-tier spellcaster certificate from the Foundation's certification exam.

"How come you have the leisure to work here?" Jiang Jinghua asked. "Aren't you busy with idol group matters lately?"

In many ways, Honoka Kousaka is a person with an excess of energy and a tendency to have mental lapses. For example, as a fourth-tier illusionist, she suddenly became obsessed with a famous school idol group and made a declaration that she would become the most popular person in all of Japan without using any illusions. More importantly, the day after making the declaration, she successfully persuaded two of her friends to join her group, and two weeks later, she successfully uploaded the video of her first song... and it actually worked! It's now a hot topic on Nico Nico Douga.

It's nothing to suddenly have strange ideas because of a mental lapse; what makes a true strong person is the ability to turn those strange ideas into reality. From this perspective, Honoka Kousaka is truly an amazing person.

"You mean idol groups... yeah, because Kotori-chan and Umi-chan have been really busy lately." Honoka sighed. "They've been busy taking their CET-4 exams and have been locking themselves at home studying for over a day and a half."

"That's really hard work... By the way, you guys didn't go to a school that teaches consciousness mechanics, did you?" Jiang Jinghua asked. "To be able to get a Level 3 certificate under those circumstances is really impressive."

"Well, we have some special channels that we can't easily tell outsiders... Okay, these will be about 1200 yen in total!" Honoka put the items Jiang Jinghua bought into a bag. "Um, since the smaller amounts at the end are too troublesome, why don't you just pay 1200?"

"...I appreciate your kindness, but to avoid the store manager causing you trouble, I'd better decline."

As Jiang Jinghua walked out of the convenience store carrying the plastic bag, he felt a slight sense of loss.

In the end, I still couldn't say anything to her, nor could I do anything to deepen our relationship.

Honoka Kousaka is a really nice person. She could recognize Jiang Jinghua, whom she had only met a few times online and who had no distinguishing features, at a glance and even struck up a conversation with him. She's probably the easiest person to get along with among all the people she's ever met. What's even more remarkable is that she's so beautiful. If she hadn't gone to an all-girls school, she'd probably be the most popular guy in the whole school by now... well, maybe she would be the same even in an all-girls school.

But I don't know why, even with girls like that, I always feel like we don't click.

Jiang Jinghua walked silently along the wide streets of Tokyo, with cars occasionally passing by.

If we rule out the possibility that some cutting-edge technology equipment is being tested on the road, then there must be at least one person in the car. That person is also a living, breathing human being, with their own life story, joys and sorrows, their own beliefs and values, things they are determined to pursue no matter what, and things they are determined to protect no matter what. He or she appeared in Jiang Jinghua's life for about three seconds, and then disappeared, never to be seen again, or if they did, it would go unnoticed.

To others, I'm just like a driver in a passing car or a cashier in a supermarket—a passerby who is neither likely nor necessary to be remembered. The reason is simple: I've never been needed by anyone.

There is nothing in this world that Jiang Jinghua can do that no one else can.

Jiang Jinghua looked up at the clear blue sky and let out a soft sigh.

He recalled the mobile games he used to play. Every gacha game has one thing in common: 90% of the cards in your inventory are useless. Those low-level cards marked with N or R are basically junk to players, or temporary substitutes until more powerful SR and SSR cards appear—like instant noodles eaten on a train, used and discarded.

Jiang Jinghua knew perfectly well that he was nothing more than an R-card, or even worse, an N-card, perhaps the worst kind of experience card, not even qualified to serve as a temporary substitute or warehouse manager. Someone like him was simply...

"Di-"

Holy crap!

The sudden sound of a car horn startled Jiang Jinghua, who quickly took a step back, successfully avoiding a black luxury sedan speeding past him.

Damn! That was almost a car accident!

Jiang Jinghua shook his head violently, completely erasing the meaningless, self-absorbed, decadent thoughts of a literary youth from his mind.

The most meaningless thing in this world is the description of the inner thoughts of passersby.

Extras should do what extras are supposed to do. After serving as a source of experience for the main character, a wingman, a source of ridicule, or a background character, they should obediently leave the stage and get their comeuppance. Don't add unnecessary scenes for yourself.

Because no one would be interested.

what

Let's make a Keter-level visual novel in Section 3, Chapter 3.

night.

Tokyo's nights cannot be called nights; they should be called another form of daylight. In fact, it's more accurate to say that Tokyo at night is the Tokyo that truly awakens. The towering skyscrapers are adorned with shimmering lights, and the artificial starry sky created by tens of thousands of lights is enough to eclipse the real starry sky.

However, none of those stars belonged to him.

After finishing the convenience food he bought from the supermarket, Jiang Jinghua went to his narrow desk and took out the official teaching material of St. Christina Academy, "Fifty Years of Spellcasting and Thirty Years of Simulation".

Jiang Jinghua is generally a diligent and good student, so he only has two pages of assignments left to complete. After finishing this last written assignment, he can begin today's lab work.

"12. Given a standard spellcasting material weighing 12.3 kg, its magic circuit structure is shown in Figure 12-a. A spellcaster inputs magic power at a constant rate of 120 Nordel per second. Then:"

"(1) If the spell formula of the caster and the graph of the Cavalier function are as shown in Figure 12-b, please point out two errors in the spell casting process and correct them."

"(2) If the magic affinity coefficient of the casting material is 1.72, calculate the average structural strength of the casting material after 30 seconds of inputting magic under standard conditions, and draw a graph showing the change in the average structural strength as a function of time."

The professors at the academy often say, "Mathematics is the mother of natural sciences." The magic now known as "consciousness mechanics" has naturally become a descendant of mathematics. Therefore, the feeling of doing consciousness-based exercises is actually quite similar to doing an advanced version of high school math problems.

"Solution: Based on the magic circuit structure given in the question, we can deduce that the material..." Jiang Jinghua began to write furiously.

The first question was relatively simple. From the graph of the Cavalier function, it's clear that mana leakage occurs at point C in the circuit diagram. Besides this, another error is quite obvious. The given spell formula and the function graph clearly contradict each other, indicating that the spell the caster intends to unleash does not match the actual spell cast.

Countless extremely obscure and difficult-to-understand formulas and textual explanations appeared like ants marching in formation under Jiang Jinghua's pen. If Jiang Jinghua were an ordinary person without magic, even if you pointed a gun at his head, he wouldn't be able to write such anti-human things.

Since there is magic for healing, magic for killing, magic for creating, and magic for entertainment in this world, there must also be magic for solving problems.

Through an indescribable and mysterious process, Jiang Jinghua's mental abilities, supported by magic, were enhanced to several times their original level.

Question 1, completed.

However, the second question was far more difficult than the first. Because the analysis of the spellcasting process is influenced by an immense number of factors, even with the aid of magic, Jiang Jinghua couldn't escape his mind becoming a complete mess. His intuition and rationality, forcibly stabilized by the magic, were crumbling, and the combined physical and mental strain caused large beads of sweat to appear on Jiang Jinghua's forehead.

Finally, after more than half an hour of arduous struggle, Jiang Jinghua finally—

"I have absolutely no idea! I'll just copy the answers!"

So, this is the fate that a passerby should have.

With the help of the answer key, Jiang Jinghua finally finished the final written exam. All that remained was the experimental assignment to create a spell scroll.

Compared to written assignments that challenge the limits of human imagination, experimental assignments were much easier for Jiang Jinghua. Drawing magic scrolls sounded impressive, but apart from constantly infusing magic in a specified way during the drawing process, this task was actually no different from ordinary painting.

Because this work required absolute concentration, Jiang Jinghua only completed three-quarters of the first layer after forty-five minutes. Fortunately, the first layer was the main body of the entire scroll and also the most labor-intensive part of the entire production process. Once the first layer was completed…

"Drip drip drip!"

The sudden notification sound startled Jiang Jinghua. His right hand trembled, and the magic potion he was writing splattered onto the magic paper, the leaking magic causing the paper to emit a sharp, metallic sizzling sound. A small, ever-expanding hole was burned into the tip of the pen. In short, the scroll was ruined.
