My youth story, a crossover anime, turns out, is FGO!

Finally, the meeting place for everyone was decided to be Akihabara.

This is not surprising, since both Eriri and Kasumigaoka Utaha are fans of anime and manga, as well as creators of ACG works; they are all seasoned otaku.

For "Kasumigaoka Utaha" and "Eriri", the simplest way to understand an isekai world is to watch the isekai anime community. It's not just about different anime series, but also about popular trends and different developments.

the most important is……

"In Akihabara, both King Arthur and Charlemagne can use Heroic Spirit Armaments!"

Sayuri Sawamura put her hands on her hips proudly and whispered to her daughter next to her, "Isn't my idea brilliant!"

"Wow!" Sawamura Sayuri exclaimed in a low, excited voice, "King Arthur and Charlemagne are so handsome! Are all Heroic Spirits like this?!"

By the way, Mr. Leonard was there too. How could these parents miss such an opportunity? Even though Charlemagne was the King of the Franks, he was still very much looking forward to it!

At this moment, Mr. Leonard successfully interjected between the two heroic spirits, engaging in conversations about men's topics, and seemed to be having a great time.

The girls were admiring her good looks.

“That’s right!” Machida Sonoko and Sawamura Sayuri hit it off immediately, and she blushed slightly. “Isn’t this great?”

Eriri looked left and right, and couldn't help but scribble a couple of lines on her sketchbook. Her eyes darted around uncomfortably, and her cheeks flushed. "It's...it's alright."

Kasumigaoka Utaha also felt the urge to write, but her reaction was the same tsundere as Eriri's: "It's alright."

Whether it's King Arthur or Charlemagne, their heroic spirits are both silver and blue in color, but their personal styles are completely different.

However, King Arthur's armor tends to be more like armor, with a full-body suit of light silver armor, as if he were about to don it and lead the charge on the battlefield, giving off a sense of both glory and menace.

As Charlemagne, who appears in the world from the perspective of adventure legends, his attire is closer to that of an adventurer. The silver and black fabric clings to his body, showing off his lean and perfect figure, and the metal armor is limited to his limbs, a style that facilitates movement.

“Actually, I also have a general’s outfit, but this one is more comfortable to wear.” Charlemagne smiled brightly. “Besides, that outfit is quite different from King Arthur’s style.”

Kasumigaoka Utaha couldn't help but nod. She had also seen Charlemagne's spirit costume as a general. Although both were kings, King Arthur was closer to a king who took the lead and charged into battle, so his costume was more practical and combat-oriented.

Charlemagne, on the other hand, was the king who commanded from the rear and oversaw the overall situation. His attire was more decorative and looked more luxurious and majestic. He even had three sets of spirit armor with completely different styles.

Of course, this made everyone extremely excited, and they clamored for Charlemagne to show all three outfits. The third outfit, in particular, with its solemn and luxurious gold and red, caused a series of exclamations. Only then did they leave the house satisfied.

The appearance of King Arthur and Charlemagne in their spirit costumes caused a huge sensation in Akihabara. Along the way, people were asking about the characters they were playing, the names of the two cosplayers, and even asking for photos.

In addition, to distinguish themselves from their counterparts, Eriri and Utaha from the other world simply let loose and cosplayed as Yukari Yakumo and Kaguya Houraisan, respectively. If Arthur and Charlemagne hadn't been so dazzling, they would have been sensational cosplayers, attracting countless eyes along the way.

Kasumigaoka Utaha's gaze lingered on the two Heroic Spirits, and her sensitive nature as a writer compelled her to write something down.

Although both were famous European kings, King Arthur and Charlemagne had completely different temperaments, as evidenced by their styles of leading armies and their clothing.

King Arthur appears more composed and gentle, like a shining king straight out of an epic legend, while Charlemagne gives off a more youthful vibe, full of vitality and energy, more like a knight-errant adventuring before becoming king, existing in a fantasy world.

If King Arthur is like a dazzling star, then Charlemagne is a dreamlike and magnificent fantasy.

It's not just his handsome appearance; his charisma alone is enough to explain why he attracts so many admirers.

Even though the streets were later blocked by too many onlookers, after they escaped, Arthur and Charlemagne changed out of their spirit costumes and into everyday clothes. Even though they were wearing ordinary clothes, they still managed to make people's hearts flutter and attract the attention of many female and even male students.

Fortunately, they were able to go shopping normally at this point.

"It's really different from where we live." Eriri looked around at the promotional posters on the surrounding buildings and the signs placed in front of the shops, and couldn't help but sigh.

“Indeed, although the overall level of prosperity is about the same, the popular content is completely different,” Kasumigaoka Utaha commented.

"What's different?" Eriri couldn't help but ask.

"Actually, it's like this..." Eriri roughly explained to her counterpart.

Although the cultural development and political situation of the two everyday worlds were probably very similar or even the same before the monster invasion, the development of the two worlds went in different directions after the monster invasion and the appearance of heroic spirits.

The ACG (Anime, Comics, and Games) field is also heavily impacted, with a large number of historical fanfiction and derivative works belonging to the ACG field, thus facing a very awkward situation.

Most works involving historical figures will likely be removed from shelves.

In the past, people could create whatever they wanted. After all, the person in question was dead, so there were no human rights issues involved, and they wouldn't sue you by exhuming their coffin. Therefore, some derivative works were incredibly unrestrained. Gender swapping of all characters was a piece of cake, and making up stories or even closely related to the eighth letter was all the rage.

However, out of the blue, the heroic spirits appeared.

They're really capable of suing countless fan-made content creators, even if it means risking their lives! And they're incredibly strong! They're heroes who protect everyone even during a monster invasion!

Ah this...

Even though most of the Heroic Spirits said they wouldn't care about fan works and wouldn't pursue previous works, and were willing to relinquish their right to create their own works.

However, the more outrageous ones were generally deleted by everyone. After all, when you're doing fanfiction, you're really pushing the boundaries of what's supposed to be the real person.

Even though the appearance of Heroic Spirits has led to a surge in historical fiction and many excellent works have emerged, the market has become quite homogenized, since it's impossible to be out of character (OOC)...

Fanfiction authors: What's the point of writing fanfiction if I can't be out of character?! It's like losing most of the fun!

Moreover, creating fan fiction also faces a terrifying group – die-hard fans or haters of Heroic Spirits.

Idols created and promoted by capital can have tens of thousands of fans, not to mention these originally outstanding heroes who are destined to be remembered in history, their fan base will only be larger.

Especially those who have immense prestige in their own countries and even the world, such as Qin Shi Huang, King Arthur, and Oda Nobunaga, or famous beauties or handsome men in history like Lanling Wang, Marie Antoinette, Maeve, and Yang Guifei, have countless fans!

For example, Lanling King, as the possessor of "demonic appearance", almost unified the aesthetics of the whole world, even though he only took off his mask once after being summoned.

Having a large number of fans increases the popularity of the Servants and strengthens their power, but it also has a very negative impact on the Servants themselves, especially their Masters.

Fans who can't even accept their idol getting married are even less likely to accept that their perfect and omnipotent king, or their stunningly beautiful and gentle virtuous woman, is spending their days with another woman or man who is completely useless, or even falling in love with him.

Just like how they humiliated Nino Nakano in the stadium ghost incident, or how they verbally attacked Eriri later on, those who came after them only did worse things.

However, unlike most idols who can't keep their partners, heroic spirits don't rely on fans for a living; fans are dispensable to them.

Just as Oda Nobunaga almost went on a killing spree over the matter of Nakano Nino, King Arthur personally stood up for Eriri, and later there were several conflicts between Heroic Spirits and those brainless fans.

The most serious incident occurred in Egypt, where Ramses II flew into a rage when some brainless people insulted Nefertari, killing hundreds of people in the street.

In addition, many Servants rose up because their Masters were treated badly, resulting in either death or crippling. During that period, the relationship between Servants and the general public became extremely strained.

Later, various countries urgently introduced relevant laws, which would severely punish any behavior that harasses the Heroic Spirit Master and their family. The endless bloodshed also served as a warning to those men and women who were blinded by fanaticism.

But relatively speaking, are heroic spirits punished after committing murder? This isn't ancient times where a subject would die for his lord's honor.

In an effort to ease tensions with modern society, all the heroic spirits gathered together, forming a loose organization and establishing some rules.

First, after a Heroic Spirit manifests, it must be registered in each country.

Secondly, if a Heroic Spirit or their Master is verbally insulted, the matter should be submitted to the judicial authorities of their respective countries for adjudication. Of course, if their personal safety is threatened, they can resolve the matter themselves.

Most importantly, it stipulates that neither heroes nor anti-heroes can use their abilities, such as magic or curses, to secretly kill ordinary humans and profit from them.

Of course, while this is the regulation, everyone knows how binding it is. It can only be said that with this consensus, the heroic spirits will not act too openly.

Outsiders should know their place at this point and not provoke others... If someone insists on courting death, no one can save them.

As a result, countries are actually relieved that the number of Heroic Spirits is not very large, only a few dozen worldwide, so even including their Masters, the actual impact is not very significant.

Therefore, later on, apart from those Masters who accidentally exposed their identities, most Masters adopted a low profile, keeping their identities and appearances completely secret. Only the Servants were active outside, and their daily lives were not affected.

The implementation is quite simple: just have Merlin cast an illusion spell. Heroic Spirits can move freely outside, but when they return to their Master's side, they can bring illusion spell items with them.

We've strayed from the topic, but it's undeniable that the appearance of Heroic Spirits has had a huge impact on entertainment culture. In the worlds of "Eri Ri" and "Kasumigaoka Utaha," while people admire and love historical fan works, the creative community itself is actually quite limited and stagnant.

Conversely, the market for other genres such as science fiction, space, and fantasy has shrunk, but various kinds of gimmicks and parodies have increased.

However, comparing Akihabara in the two worlds reveals that Akihabara in the world of Servants is not as vibrant and diverse as Akihabara in the everyday world. Given the high popularity of Servants, many promotional materials and works tend to favor them.

"Hey! Looking at it this way, putting everything else aside, the ACG culture of the two worlds is indeed very different..." After hearing the explanation from her counterpart, Eriri felt her scalp itch, as if something was about to grow out.

"After all, we really do have extraordinary powers on our side. It's a good thing and a bad thing." Eriri sighed. It's not that the appearance of Heroic Spirits is all negative.

At least with the help of magic and Noble Phantasms, many diseases are no longer incurable. At the same time, the scientist Heroic Spirits are also driving the development of technology. In just over a year, the world where the Heroic Spirits live is like it has been put on an accelerator, and many things have been invented.

“For example, this.” Eriri tapped the watch on her wrist. A holographic screen, which had only appeared in fantasy works so far, appeared above the watch. She demonstrated it and then turned it off. There was no signal here. “I never would have dared to imagine this before.”

"That's amazing!" Machida Sonoko covered her mouth.

“And even with limitations, the collision of extraordinary and everyday thinking can give birth to truly outstanding works,” Sayuri Sawamura couldn’t help but interject. “I really want to visit Eriri’s world.”

"Actually, I prefer the free atmosphere here," Eriri couldn't help but complain. "I can't even get into a comic convention normally over there!"

Not to mention selling doujinshi. In the past, her parents helped her sell them. Later, Leonard and Sayuri Sawamura also became celebrities. Although the fact that Princess Ooya is an 18r doujinshi artist was well managed and could become a popular selling point, she is still King Arthur's Master. What if others misunderstand that she and Arthur just play around like this?

Eriri didn't want readers to use her doujinshi to fantasize about Arthur, so she had to keep Eri's identity a secret. Later, she had to ask someone to help her buy a doujinshi, or have Merlin add a filter to it.

"After all, there are gains and losses." - Kasumigaoka Utaha's comment.

“Of course you’d say that if you’re unaffected!” Eriri puffed out her cheeks.

Kasumigaoka Utaha's identity is well hidden. Although she initially naively thought that being a Heroic Spirit Master could help with publicity, she quickly changed her mind. At the same time, Kasumigaoka Utaha didn't want readers to come because of Charlemagne's name. In addition, Charlemagne was also very careful, so her daily life was not affected.

Unlike Eriri, who can't even go back to school.
