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

"Aaaaaaaaa!!" Tiamat cried out in anguish. She seemed to have encountered a future of death. She began to transform again. She wanted to evolve and become stronger in order to deal with the siege of the Heroic Spirits.

Even the wings on her back continued to grow, still blotting out the sky, as she wanted to escape this underworld, to escape this world of only death.

"Don't even think about escaping!" Aoki Makoto noticed Tiamat's intention and called out a name: "Enkidu!"

"Understood, Master."

On a distant Earth, a beautiful woman with long, vibrant green hair closed her eyes slightly.

It wasn't that Makoto Aoki didn't want Enkidu to participate in the space battle, but as the wedge between man and god, as Enkidu possessing the wisdom of the people, and as the Chain of Heaven, only Earth was his home ground, and on the earth, he would receive the greatest blessing.

There's no need to feel it's far away. Even the difference between heaven and earth is just a fleeting moment for the Heavenly Lock that connects heaven and earth.

"Hahahaha!!" Gilgamesh roared with laughter. "My friend! Let me once again witness the glory of your binding the Mother Goddess of Creation!"

"Mother."

Enkidu's eyes, like spring buds, were tinged with a divine golden hue. A powerful torrent of magic transformed into golden lightning that swirled around him, and invisible wisps of light surrounded him, reflecting Enkidu's beautiful smile.

"The Age of Gods has passed; now it is the age of humanity."

A continuous stream of golden chains emerged from the golden ripples. The green-haired hero spread his arms and soared into the sky, a tremendous light emanating from his body and merging into the golden chains.

Gradually, his body transformed into a cone of light, within which a massive golden wedge, accompanied by chains, swept across a vast distance in an instant, and Enkidu returned to his original form as he was created.

"What has been awakened is the breath of the stars; I will walk alongside humanity. Therefore—"

"O mortals, hoping to bind the gods (Enuma Elish)!!"

He transformed Enkidu's own body into a divinely created weapon.

Transforming into a nail of light, it injects the "restraining force" known as Alaya or Gaia, transforming the immense energy into a form (wedge) that the world can recognize, piercing and fixing the opponent with a single strike.

Its power increases dramatically depending on the destructive acts committed against the planet or against humanity.

For Tiamat, the beast of return to the evil of humanity, Enkidu, empowered by the pseudo-Fou, can undoubtedly exert the greatest force.

"Aaaaaaaa——Aaaaaaaa——"

After the light faded, Tiamat let out a mournful cry. Her enormous body was bound by golden chains, and Enkidu, who had turned into wedges, firmly pinned her down, preventing her from escaping.

“Ah, my friend.” Gilgamesh’s eyes showed a look of satisfaction. “I will always be proud of your beautiful figure, and I will never forget the way you bound the Mother Goddess of Creation.”

The Chains of Heaven emitted a clear, cool sound, as if echoing Gilgamesh's words.

Makoto Aoki did not let himself be overwhelmed by the shock. He decisively said, "Stars, sing."

He unleashed the power of Funny Vamp, granting all the combat Servants a tremendous boost. Their magical energy seemed to flow endlessly, and they gained immense resistance to Tiamat's corruption. This blessing from Earth, along with Noble Phantasms like the Great Wall, fought against Tiamat's Sea of ​​Life.

"Flow, collapse!"

A rainbow-colored light bloomed in her pupils, locking onto Tiamat. Having grasped the concept of death, Tiamat also sensed her own decay, her gradual descent into death—a process that, given her life force, would be incredibly long.

With Tiamat bound and unable to bear children, this is undoubtedly her weakest moment.

"Now!"

However, without Aoki Makoto's reminder, the other Heroic Spirits swarmed forward and unleashed their Noble Phantasms.

Magic transformed into a beautiful lotus flower that bloomed beneath his feet. Arjuna stretched out his hand, and Shiva's destructive power transformed into a black sphere in his hand. The energy within, capable of destroying the world, caused the surrounding space to crack slightly.

Unlike usual, when he only limits his Noble Phantasm to one-tenth of its power, Arjuna now removes all restrictions and fully utilizes Shiva's destructive power.

"Divine domain expands. Space is fixed. Divine punishment execution period set—all confirmed. With the wrath of Shiva, I sever your lives here. Pashupata, the Hand of the God of Destruction!"

The dark light spread out and engulfed Tiamat. Its destructive power was too much for Tiamat to bear. She struggled desperately, and the Chains of Heaven cried out, but still bound her.

Unfortunately, Tiamat's divinity was too high, limiting the power of the Hand of Destruction. Although Tiamat was badly injured, her core was not damaged.

“We’re still far from it,” Arjuna said with a look of resentment.

Romulus, the founder of Rome, revealed a dignified yet benevolent expression: "Do not blame yourselves; you are all Rome."

"Looking up at the sky and down at the earth, this is Rome, the original mother. As a mother, she will always watch her child leave."

"Everything, everything will be pierced by my gun—my gun penetrates all things! (Magna Voluisse Magnum)!!"

Romulus planted his spear, creating "the past, present, and future of the imperial city of Rome," which transformed into an endless sea of ​​trees that surged toward Tiamat like a raging torrent.

The civilization of Rome, and the civilization of humankind, dealt a heavy blow to the primordial mother.

Gilgamesh's treasure trove has been fully revealed, and the genuine Honkai Impact 3rd is far superior to the counterfeit.

An endless rain of golden light fell upon Tiamat like meteors. Her body was already mutilated, and in order to conserve magic, it was even shrinking continuously.

"Hahahaha!! As expected, this battlefield won't end until everyone is left behind!"

Before I saw the person, I heard his voice first.

"It's gold; it seems I still have to make a move!"

Gilgamesh chuckled and crossed his arms: "Damn it, I simply haven't used my full power yet."

Then, Gilgamesh poured himself a potion that would make him younger, and his body began to change. Red divine runes climbed up his snow-white, strong body, and golden armor was put on him.

"Hahaha, behold my glory! The King of Heroes has condescended to be here!" Gilgamesh, whose class has even changed, has returned in grand style.

As the golden ship representing the sun descended, Ramses II laughed arrogantly: "Tiamat's life is mine to take. Bow down before my glory, golden one!"

"Oh? This is clearly my prey, don't get it wrong, it's the sun's," Gilgamesh said unhappily.

These two, even with a formidable enemy at hand, still want to show off.

The surrounding heroic spirits felt uncomfortable.
