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

"Ren is such a big idiot—"

Eriri Sawamura threw down those words and, unable to bear it any longer, rushed out.

She didn't know where she had run off to; she just leaned against the wall and slumped down, utterly exhausted.

"Idiot, idiot, idiot, idiot..."

Eriri kept cursing, but tears kept streaming down her face.

Is she the only one who still remembers her childhood wish? Eriri has asked herself more than once, should she continue? Or perhaps, even Eriri herself doesn't know what this feeling truly is...

Because Aki Tomoya will not respond to her.

"Yinglili."

It was Tomoya's voice.

"Why are you coming to me at a time like this?!" the blonde girl with twin ponytails growled. She didn't want to be like this, but she could never help herself. In fact, she hated herself just as much.

She wanted to be as naturally close to Kasumigaoka as she was to Kazutomo, and to get along as freely as Megumi, but she always ended up like this.

"Eri, I..."

Aki Tomoya pushed up his glasses, unsure how to comfort Eriri. After all, compared to his boundless enthusiasm and eloquence in the otaku world, he was just an indecisive and indecisive high school student in the real world.

Should she forgive him? Should she pretend it never happened and act as if nothing had happened? Eriri was still hesitating when suddenly, something unexpected happened.

"Ah-"

A woman's scream pierced the sky, and then Eriri heard a voice.

There was a sound of something chewing, and the whole building seemed to be trembling. Through the windows of the corridor, the light of the setting sun was completely blocked by the unknown giant object, and only red and blue fur and pitch-black skin could be seen.

"What's that, Eriri!" Aki Tomoya also noticed the strange thing outside. "An earthquake? No, could it be a monster invasion, and we're supposed to fight them together...?"

This hardcore anime fan hasn't realized the seriousness of the situation and is engrossed in his own excitement.

Shut up, you idiot!

Eriri sweated profusely from her forehead; the immense pressure rendered her speechless, unable to utter a word of protest.

Click click click.

The chewing sound was like the footsteps of death. Soil and sand fell on her, and then, dawn broke, casting a huge shadow over her. The blonde girl looked up.

That was a colossal object that could not possibly exist in the human world.

Even the teaching buildings of Toyonosaki Academy look small in comparison. Its rune-covered tusks gleam with a metallic sheen, and it is draped in a crimson color from hell and an icy blue from the polar regions. A demonic boar from the Age of Gods roams the playground.

It lowered its head, opened its huge mouth, and bit off a corner of the teaching building. Scattered cement blocks and steel bars fell from its mouth, and it swallowed the steel bars as well without caring.

In one corner of the dilapidated school building, the terrified face of a blonde girl was revealed.

The demonic boar seemed to notice, tilting its massive head slightly. It didn't matter; it could easily devour anything, steel or flesh, just like death itself, which was approaching with a ruthless force.

Run! Run!

My mind was screaming alarms, but my legs were so weak I couldn't even stand up.

Eriri's first reaction was to go see Aki Tomoya.

She wasn't expecting him to come and save her, but rather...

Renya, run!

Aki Tomoya, who had been boasting just moments before, was so frightened that he fell to the ground. The palpable, bloody wind and the ferocity of the beast instantly pulled the otaku out of his reverie, and his whole body trembled.

Upon seeing Eriri's gaze, he instinctively avoided her, lacking the courage to come to her rescue.

Under the shadow of death, Aki Tomoya truly realizes that he is just an ordinary high school student.

He instinctively stepped back.

The light in Eriri's eyes went out in that instant.

"Sawamura-kun, run!"

At this moment, it was Kasumigaoka Utaha who called out. She had actually found Eriri, but she hadn't shown herself because of the situation earlier.

At this moment, she was so frightened that she could hardly move, but she still managed to warn them.

Yes! Escape!

Eriri felt a surge of strength returning to her body. She forced herself to stand up and took heavy steps, trying to escape, even though she knew it was futile.

The giant demonic boar was unaware of the complex thoughts of the tiny creatures below. After all, it was a demonic beast that slew heroes. Eriri's golden hair caught its attention, and it opened its mouth, its stench and saliva enveloping Eriri.

There's no escape!

Eriri felt a wave of despair. Was she going to die?

No! Being eaten by a monster is just too terrible!

The blonde girl's eyes were tightly closed, her whole body trembling. She instinctively hugged herself tightly, but she could only accept her fate.

"Sorry, I offended."

It was a voice gentler than the spring breeze, and a faint scent of roses that masked the stench of the demonic boar. Eriri felt as if she had fallen into a solid embrace.

My body felt light, yet an indescribable sense of security enveloped my heart.

Eriri opened her eyes, tears still glistening in the corners.

This was literally solid; the man holding her was wearing armor typical of medieval Europe, primarily silver-blue that reflected a pale silver light, with blue patterns on his chest that Eriri found somewhat familiar.

Looking up, one could see his perfect jawline and pale lips, while his face was obscured by a black and white hood, giving him an air of mystery.

The sound of wind rushing past her ears made Eriri realize that she was actually in mid-air—

"Ahhhh-"

This is the pitiful scream of a certain blonde-haired loser.

"Please be careful, ma'am."

After her feet finally touched solid ground, Eriri heard his pleasant voice again. His words were as polite and distant as those of a medieval knight. Once he was sure Eriri was on her feet, he quickly let go of her hand and stood aside.

Eriri was finally able to see his full appearance.

He was a knight who seemed to have stepped out of an ancient heroic epic. He was covered in silver armor and his blue robes concealed his entire body. Even with a hood, he did not give off a sneaky feeling, but rather appeared mysterious and awe-inspiring.

Saving Eriri didn't seem like anything special to him. He looked up and saw that the only opponent was the demonic boar in front of him.

The knight's hand was loosely clenched, as if he held an invisible giant sword.

"I... thank you..."

As the knight was about to leave, Eriri mustered her courage to thank him, but her throat became so dry that tears streamed down her face.

very scary.

Ultimately, Eriri is just an ordinary girl; fear has left her weak and unable to move.

He seemed to pause for a moment, then reached out and patted Eriri's shoulder, chuckling, "Leave it to me."

I felt instantly relieved.

Eriri felt the weight on her shoulder, as if a force was being transmitted from there, making her whole body feel warm.

"Mmm." She smiled at him through her tears.

The knight nodded slightly to her, then turned to stare at the behemoth before him: "The demonic boar of the Age of Gods, a being that devours flesh and gnaws at armor, has come to an end!"

Seemingly sensing that the knight before it was a formidable foe, the demonic boar pawed at the ground restlessly, instantly raising clouds of dust. It was gathering its strength to unleash its deadly charge.

If the demonic boars were to crush them, the school buildings at Toyonosaki Academy would collapse, and countless people would be killed or injured.

The Silver Knight was not afraid. He took to the air, diverting the boar's attack and moving away from the teaching building.

The screams echoing throughout the building were for no one in particular, but Eriri couldn't take her eyes off them.

So beautiful.

Whether soaring through the air or wielding that invisible giant sword, the knight displayed a beauty completely different from modern aesthetics. It was the fearlessness and courage of a hero facing beasts with his flesh and blood, before the invention of firearms.

However, the knight was not as adept as Eriri had imagined.

Very strong.

After all, it was the boar that slew the hero Diarmuid, so it was impeccable in both strength and defense.

If one does not wield the Star Sword, ordinary weapons are not even qualified to leave a mark on it.

Fortunately, this body is that of a knight who targets and hunts giant beasts.

There is no need to unleash the Noble Phantasm.

The knight made a calm assessment.

Then let's end it with this one strike!

Seizing an opening, the knight leaped into the air, his holy sword aimed at the boar's massive head, and a hurricane that seemed to tear everything apart swept forth.

"Strike Air (Wind King Barrier) -"
