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

Yellow sand was everywhere.

As far as the eye can see, there are only desolate sand dunes and yellow sand, devoid of any life, with only the wind blowing and stirring up some dust year after year.

Huge, furnace-like steel gears hovered in the air, interlocking and slowly turning, while below them, countless nameless, lonely sand dunes stood, covering the endless yellow sand.

Here lies an endless tomb made of swords.

It is also a sword mound he created during his lifetime, using the origin of the sword and the treasures he used in projection magic.

Those were the remains and blood he left behind in endless battles, his memories filled with endless struggles, each sword belonging to a hero who had fought him.

Archer deliberately controlled the range of his Reality Marble, ensuring that he was the only one present without affecting the stability of the Land of Shadows.

"O Tiamat, the primordial mother."

Red A looked at Tiamat without any pity or complicated emotions. He had experienced too many battles, and he had killed any opponent, whether good or evil, old or young, who posed a threat to the continuation of humanity.

"As beast2, you possess the power of Nega Genesis, and you have great patience for the Noble Phantasms of Servants born from the correct history of humanity."

“However, I am not,” said Red A, or rather, the man named Shirou Emiya, as he held his usual black and white Gan Jiang and Mo Xie swords. “I am just like you, an anomaly in the history of humankind.”

"Neither you nor I should stay in this world any longer."

"Awaken, O First Mother."

Emiya Shirou was not originally a Heroic Spirit that could be summoned in this world, because the future of this world did not include that tragic man whose origin was the sword.

Emiya Shirou was successfully summoned through another possibility.

He is a man who strives for the future, a "partner of justice" in the dreams of countless people.

Shirou Emiya is indeed a human being from the origin, but he represents countless tragic figures who fought for justice on the battlefield, only to fall silently in the end.

In other words, his true name engraved on the Throne of Heroes should be "Untitled".

Not every hero of justice will have their name etched in history; too many nameless heroes have fallen in the past, leaving no trace.

As an unsung hero, Shirou Emiya, a member of the fictional Heroic Spirits, answered the call to action.

As an entity with an incorrect history of humankind, Tiamat's anti-Genesis had little effect on him.

Therefore, Red A charged out, risking his life in order to achieve the greatest results.

That solitary figure, like in many of his battles, held a sharp blade and fought alone.

"It's just the two of us here, no one else, Beast 2!"

“Aaaaaaaa——”

Tiamat didn't react much to the change in the environment. Her star-shaped eyes, flashing with a cross, were fixed on the red-clad heroic spirit charging towards her. She opened her huge mouth wide, and an invisible sonic wave swept out like a hurricane, sweeping towards the red-clad heroic spirit.

"Rho Aias!"

The seven-layered shield, blooming like flower petals, blocked Tiamat's attack, while the Seven-Layered Radiant Ring, unable to unleash its true power, quickly shattered, turning into magical particles and disappearing from Red A's fingertips.

Close combat would be very difficult.

Red A's eyes were resolute, and all the magic circuits on his body surfaced, the shimmering blue light becoming incredibly hot, as if it were about to burn away his life.

"Pfft!"

An unnamed blade plunged into the sand dune at Red A's feet from afar.

A handful.

"Pfft..."

Two rounds, a hundred rounds, a thousand rounds, ten thousand rounds...

More and more swords came from all over the mental barrier, and they gathered around Red A like soldiers in neat rows.

It channeled all its magic power, causing even its magic circuits to groan under the strain, and all the swords within the entire Reality Marble rose from the ground.

"—"

Like the sound of a sword being drawn from its sheath, the sky was instantly filled with countless blades and weapons.

Cursed demonic swords, noble holy swords, sharp blades, swords from the East and the West... countless "swords" gleaming with metallic luster hovered in the air, filling the entire field of vision.

A black rain of swords, obscuring the sky, pointed their tips at Tiamat, their cold gleam gleaming.

Red A nearly collapsed to his knees, his magic power depleted, leaving him utterly powerless.

"Shirou."

Located in a safe place, Shiina Mana, who had already tried to leave her home and was constantly drawing to encourage others, unconsciously put down her paintbrush.

The paintbrush fell, leaving an ugly red stain on her white clothes, but Shiina Mashiro was completely unaware.

She could sense that the other end of the contract had been faintly visible since the beginning. She could feel that Shirou was in pain, and that pain was even transmitted to her through the contract.

Tears streamed down her face as past scenes replayed in Shiina Mashiro's mind.

Shirou dressing her, Shirou cooking for her, Shirou taking her to see fireworks—all these scenes are cherished memories for him.

Shirou is always very gentle.

The fabric above her knees was soaked with tears as she raised her right hand.

The Command Seals on it, which looked like a palette of paints, emitted a red light, and the scorching temperature was like flames, but Shiina Mashiro did not move at all.

No matter how ignorant and foolish she was, she knew that she was going to lose Shirou.

I hadn't even figured out what those feelings were, and I hadn't even had a chance to say goodbye before the farewell came so suddenly.

but!

Shiina Mashiro's ruby-like eyes were filled with determination.

"Shirou! Go do what you want to do!"

Shiina Mashiro felt the unwavering will and determination coming from the other side of the contract. She had been causing Shirou so much trouble... This was her way of repaying him!

The three Command Seals, along with all the magical power that Shiina Mashiro poured into them without regard for anything else, surged into the other side of the contract.

"truth……"

Red A felt the overwhelming magic, his expression was complicated for a moment, but then he became determined again.

"I'm sorry, Mashiro."

The red-clad heroic spirit's eyes were resolute: "If there's a next time, I'll apologize to you then."

Unfortunately, there probably won't be another chance...

Once again, the magic power within the magic circuits was squeezed out, and several brilliant sword shadows reappeared amidst the black rain of swords: the Wheel of Victory, the Blade of Juvayus, the Undying Supreme Saint...

"Aaaaaaaa!!" Even Tiamat felt the pressure; she opened her enormous mouth, intending to strike first.

That's not enough! That's still not enough!

In my distant memory, the figure of that king flickers before my eyes, as warm as a spring day, and I was later redeemed.

Even if it wasn't Shirou Emiya's experience, as the one who was saved, the king was willing to reach out to this similar yet different person.

"Shirou..."

Golden particles of light took shape in his hand, and that dreamlike form was a holy sword forged from a planet.

Red A raises his golden sword high and chants his true name.

"The eternally distant golden sword (Excalibur Image) —"

The brilliance of the holy sword, accompanied by an endless rain of black swords falling from the sky, instantly engulfed Tiamat.
