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

You should know that there is something in this world that is more terrifying than physical death.

Social death, commonly known as social death.

For example, if every man who died suddenly while studying "study materials" under the covers late at night could still speak, his greatest wish would not be to be resurrected, but to physically smash his phone, or delete his online browsing history and shred his hard drive.

Eriri and Kasumigaoka Utaha understand that it doesn't matter to their parallel universe selves, since everything they do has no impact on them, and ultimately it's the two of them who have to take the fall.

Death is acceptable, but social death is absolutely unacceptable!

So Eriri and Kasumigaoka Utaha walked along, keeping a close watch on everything, even glancing at the dogs on the street, afraid of being noticed that the two most beautiful girls from Toyonosaki Academy had come to a love hotel together, and even brought club members along, seemingly to engage in a 4P. Well, actually, they were very well hidden, completely unaware that Ogawa had already spread the news of the two most beautiful girls dating throughout the entire school.

"What are you doing? Performance art?" Kasumigaoka Utaha, who opened the door, raised an eyebrow and looked at the four "little black people" in front of her with a suspicious look.

Their bizarre appearance, with only their eyes visible, resembles the criminal suspect Xiao Hei, who frequents the Conan movie set next door. They look so furtive that one can't help but want to shout "Officer!" and bring them to justice.

Two of the "little black men" kept their heads down and couldn't wait to squeeze into the room. Then two more "little black men" filed in. This was the first time the room, designed for couples, had welcomed so many people, and it instantly became crowded.

"Haaah, haaah..." As soon as she entered, Eriri couldn't wait to throw off the black cloak covering her face. Her cheeks were flushed, and she gasped for breath. "You two, what are you doing coming to a place like this?!"

"It's nothing, you're a doujinshi artist after all, haven't you ever come here to gather material before?" Kasumigaoka Utaha said calmly. "Besides, we don't have identification, and going to those small hotels isn't safe or private enough."

"If I'd known it would be like this, I would have lent you my student ID." The other Kasumigaoka Utaha lifted her black cloak and fanned herself with her delicate hand. "At least I could stay here."

"Pfft!" Eriri, who was in the room behind them, walked over and burst out laughing, "Where did you get all these weird clothes?"

With a flick of her finger, everyone could see the huge words "burn burn burn" and the enormous "fff" logo on the back of the black cloak. Just looking at it, it exuded a strong sense of resentment. It was likely that the four of them wearing this outfit and parading around the city would attract more attention than if they were dressed normally.

"Well, this was found for us by Tomoya-san. As soon as Sawamura-san heard that we were meeting here, he resolutely refused to come, and even if he did come, he refused to show his face, so we had no choice but to wear this." Kato Megumi explained in a very good-natured manner, as she took off the cloak and hung it aside.

"Stop nagging!" Eriri shouted in response, tugging at her cloak. "As a result, with everyone on the street staring at us while we're wearing this, it's really..." She covered her face in embarrassment, her ears turning bright red through her golden hair.

"It's okay. As long as we don't show our faces, no one will know who we are." Kasumigaoka Utaha said calmly. "As long as no one knows who we are, this matter is as if it doesn't exist."

That makes so much sense, no wonder it's Xia Shizi!

"Ahem!" Aki Tomoya coughed lightly and explained, "That's the Saint Cloth of the FFF group. I heard they even wore it to a parade at the last anime convention, and their slogan was supposedly: Burn, burn, burn! All lovers in the world become brothers and sisters."

"Ugh, what a vicious curse." Eriri instinctively hugged herself tighter.

"Why is Tomoya so familiar with this? He even knows where the other members' clothes are?" Kato Megumi noticed the blind spot.

“What a joke.” Aki Tomoya pushed up his glasses, which reflected a sharp light. “The FFF group is an organization from ‘Baka and Shoukanjuu’. I know everything about anime.”

"Of course, most importantly, I am also a member of the FFF group and have participated in sacred processions."

Aki Tomoya was incredibly proud.

However, the people around him just wanted to complain.

No way! You, a social butterfly surrounded by beauties, apologize to the FFF group. You haven't grasped the essence at all!

Aki Tomoya looked around, fully displaying the curiosity of someone visiting a love hotel for the first time, while exclaiming, "Look, there are even classrooms here! Oh, and matching outfits too!"

He ran into the classroom, pulled out a sailor uniform and a tracksuit from the locker next to him, and then blushed: "These are way too short!"

"Yes!" Eriri, who is a doujinshi artist, has overcome her psychological barrier and is excitedly looking through doujinshi with Aki Tomoya to find inspiration.

She held up the short athletic top and gestured, "This is practically the same as not wearing anything at all."

"Speaking of which, when I passed by outside, I saw a room themed around trains." Eriri's eyes were sharp, her tone low, and she gasped, "Train perverts... They really know how to have fun."

“This…” Aki Tomoya pushed up his glasses, the lenses reflecting light. “This kind of subject matter isn’t very good, is it? Absolutely not 18+!” Although he’s a hardcore anime otaku, Aki Tomoya surprisingly doesn’t play with any 18+ content, making him a breath of fresh air among otaku, though he doesn’t seem very bright.

"Shut up!" The famous adult doujinshi artist, Ms. Hakuki Eri, gave her childhood friend a sharp rap on the head.

"Look, look!" Aki Tomoya flipped through the art book on the table. "They also offer free orders and can send over costumes for cosplay. Ah, it's Chun-Li's costume!"

He held up the picture book for everyone to see, but was this really something worth sharing?

"This, this is..." Eriri opened the drawer below the TV, blushing as she looked at the pay-per-view items inside. As others looked over, she slammed the drawer door shut like a thief, shouting, "There's nothing here! There's nothing in here!"

This is exactly what they mean by "protesting too much here."

Kasumigaoka Utaha sighed and facepalmed, "Are you guys house-destroying dogs? You're curious about everything!"

Eriri casually brushed a stray hair from her temple, but retorted sharply, "Mind your own business."

Aki Tomoya awkwardly scratched his head: "I'm sorry?" His attitude of admitting his mistake was good, but he was determined not to correct it.

"Alright, now we can talk properly about why you came here, about your world, and more!"

Kasumigaoka Utaha exclaimed imposingly, "Princess, lord, tell me the truth!"

"Hmm, well, how should I begin..." Kasumigaoka Utaha wasn't buying into her other self's act. She looked completely lost in thought. "You have too many questions. Let's take them one at a time."

As expected, she was indeed difficult to deal with. Kasumigaoka Utaha crossed her arms and said, "Alright, let's start by talking about why you came here."

"Oh, that's how it happened. Why are you looking at me?" Eriri showed her two cute little fangs. "That's how it is. Kasumigaoka and I were just in the clubroom for a while when we ran into you guys."

"Nothing unusual happened along the way, not even a hint."

"So, even you didn't notice, and you unintentionally came to this world?" Kasumigaoka Utaha frowned. "No, that doesn't explain anything."

"How do you know that it was you who traveled through time, and not us who came to your world? After all, in theory, it shouldn't be possible to distinguish between them."

This is indeed a problem! Eriri, sitting on the side as a backdrop, and Tomoya Aki looked at the parallel world duo with clear-eyed stupidity on their faces.

Oh, Kato Megumi remained very calm throughout, and even had the leisure to brew a few cups of tea and bring them over, placing them considerately in front of everyone.

"Thank you." Eriri took it and started chugging it down, finally easing her dry throat. "This is special in our world, well, actually, it doesn't hurt to tell you."

"Kasumigaoka?" Eriri called out to Kasumigaoka Utaha as if seeking her opinion, since they were allies now, and it was only natural to inform her.

"Whatever." Kasumigaoka Utaha said indifferently. Even though they were always at odds, she was actually treating the other person as an equal.

After all, Eriri had been a princess for a year, so it's impossible for another Kasumigaoka Utaha to fool her.

Besides, it's good that Eriri is willing to talk about it; she doesn't want to explain so much, it's too much of a strain on her voice.

Speaking of which, is Eriri's talkativeness a side effect of her speaking tours when she was a princess? Kasumigaoka Utaha's thoughts couldn't help but wander off course.

"Look at this."

Eriri extended her right hand, and three Command Seals, as distinct as paintbrushes, were clearly visible on the back of her snow-white hand. In fact, she had used Command Seals before, but Makoto Aoki later used the Greater Grail to complete the Command Seals, so there were still three in the end.

“This is…like a tattoo.” Kasumigaoka Utaha leaned closer to examine it. “I have something similar on my other hand, right? What is this?”

Sensing everyone's gaze, Kasumigaoka Utaha separated her arms, raised her right hand, revealing a bright red pattern on the back of her hand that resembled a fountain pen, strikingly similar to Eriri's, yet also different.

"Could it be that, like the Chosen Children, it's a special mark?" This excited guess from Aki Tomoya, a fanatic of anime and manga, is, in a way, quite accurate.

“You could say that, it could be considered a contract.” Eriri continued, “From what I’ve observed, there shouldn’t be any special abilities or strange things in your world, right? Well, aside from the rumors online, which are of unknown veracity, they’re all baseless fabrications that the authorities don’t acknowledge.”

Despite her constant bickering with "Kasumigaoka Utaha," the love hotel had computers, and they had just confirmed that there were indeed no news reports of monster invasions or heroic spirits appearing in this world. Even though there were rumors similar to urban legends, there was no concrete evidence; they were just rumors.

Adding to the reactions of Eriri and Utaha Kasumigaoka in this world, it's clear that this world doesn't exist, or at least there are no extraordinary events happening around their counterparts.

"You mean your world has real..." Eriri's words revealed a lot of information, and the other Eriri stood up excitedly, quite surprised.

"That's amazing." Kato Megumi's face showed no surprise at all.

Kasumigaoka Utaha couldn't help but change her posture, and the way she kept tapping her toes on the ground showed that her heart was not as calm as it appeared.

As for Aki Tomoya, he's practically going crazy.

"A real, truly extraordinary event?!" Aki Tomoya was already in a frenzy. "No way, a special power has really appeared in this boring daily life! Damn it, why didn't it appear next to me? I don't want to continue this boring daily life, I want to go to that world too!"

"Um... after the game is finished."

After being glared at by the women around him, Aki Tomoya gave up and touched his nose.

Eriri rolled her eyes. It was precisely because she knew what kind of person Aki Tomoya was that she and Kasumigaoka Utaha found it troublesome. This guy was a typical one-sided hothead, always asking questions until he got to the bottom of things, and he was extremely egotistical and wouldn't listen to any advice.

The reason for not excluding him is simple: if he doesn't know the details, Aki Tomoya will find out on his own, and who knows how much trouble that will cause. It's better to keep him under our noses. With so many people around, we can at least keep him in check.

Moreover, putting everything else aside, Aki Tomoya will try not to cause any major problems before the game is finished, which is his biggest weakness.

"Then, is the extraordinary power you mentioned in your world related to this mark?" Kasumigaoka Utaha asked earnestly.

"You could say that this mark is what we call a Command Seal, serving as proof of a contract with a Servant."

Even now, Eriri and the people of that world don't really understand the forceful command function of Command Seals. At most, they know that Command Seals can be used to strengthen Servants... Although they all have their own guesses, no one has actually tried it. This is not a Holy Grail War that only lasts for 7 days. If they really offend their own Servants, aren't they afraid that they will betray them in a righteous way?

After all, there are only three Command Seals. You're not "Eri" who has the merit of participating in the Holy Grail War. Why should Makoto Aoki help you out? Just because you're arrogant?

Don't assume that there are many scoundrels like magicians. Magicians are scoundrels because they have the ability to control Servants (of course, the next time an idiot will be killed). What do Masters in the everyday world have? Do they make Servants cry and beg their Masters not to die?

"And the Servants are what I want to specifically talk about, the differences between the two worlds."

Eriri cleared her throat twice, looking with satisfaction at the four people in front of her who were sitting upright like obedient children, looking at her with expectant eyes.

"Our world was invaded by monsters a year ago."
