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

"Hmph, what a weak attack."

Gilgamesh, standing on the platform outside the castle, sneered: "Even if this is not Uruk, it is far too presumptuous of you to think that you can break through my carefully constructed defenses with an attack of this level, you bastard."

"After all, he is King Gilgamesh, he is so reliable!" Makoto Aoki promptly offered a compliment, of course, this reliability specifically refers to C-level Flash, not A-level Flash.

"This is only natural. Praise me as much as you like." Gilgamesh raised his chin with a reserved air, his crimson serpent eyes coldly gazing at the distant Hanging Gardens.

"I hate being looked down upon. The heavenly position belongs only to the one and only king of heaven and earth. Moreover, the Holy Grail is mine. Those bastards who dare to covet the Holy Grail deserve their just deserts."

“Moreover…” Gilgamesh narrowed his crimson eyes, “It’s such an unpleasant aura, that incompetent and wicked goddess—”

At the same time, Semiramis's beautiful eyes reflected the extremely dazzling golden spirit atop the castle.

“That attire…” Semiramis subconsciously pursed her lips, “…a heroic spirit from Babylonia?”

The Assyrian Empire was a dynasty that rose to power after the decline of the ancient Babylonian and Ur kingdoms. Semiramis was naturally familiar with that era because he revived the temple of Ishtar, and Semiramis was even regarded as the incarnation of Ishtar.

It's no wonder Gilgamesh was unhappy. Compared to Ishtar, who became slightly cuter after fusing with Rin Tohsaka, Semiramis's cruel and selfish side was definitely the kind of person Gilgamesh hated the most.

“Which one…” Semiramis pondered, “Hammub? Nebuchadnezzar II? No, impossible, it must be Gilgamesh?”

“Yes, Gilgamesh, the oldest hero-king.” Amakusa Shiro Tokisada had already seen through the true name with his true name. He glanced at the other Servants and said, “I have truly encountered a formidable enemy.”

"Scáthach, the Queen of the Land of Shadows; Oda Nobunaga, the Demon King of the Sixth Heaven; Taikomochi, the mastermind of the War of the Gods; Sakata Kintoki, one of the Four Heavenly Kings of Raikou; and Gilgamesh, the oldest hero king."

Amakusa Shiro Tokisada saw through the other party's true name: "In addition to Siegfried the Black Saber who has joined them, Astolfo the Black Rider."

"And then there's Black Assassin. After his battle with Lancer, he hasn't shown up again. Was he defeated by a third party, or did he join them?"

Even if they are defeated, it's still five against seven, a truly hopeless situation.

Semiramis was unusually silent for a moment, after all, the lineup for this Holy Grail War was a bit too much, with top-tier Servants appearing one after another.

“But that’s what heroes are like. Even if they know their opponent is strong, they can’t back down. Instead, they will rise to the challenge.” Even in the face of such a hopeless disparity, Amakusa Shiro Tokisada was not too discouraged. He looked at the white-haired Sun God Child and said, “What do you think, Lancer?”

“Leave the enemy’s Saber to me,” Karna said calmly. “If the Black Assassin appears, I will try to stop him.”

"I will pave the way for you and fight to the last moment."

As soon as Karna finished speaking, he flew directly into the air, with a blazing sun spreading out behind him, its intense heat distorting the air itself.

“Brahma, curse my body (Brahmastra Kundala) —”

Like a great sun falling, Karna hurled the "Undying Blade" from his hand.

Karna's Noble Phantasm against the nation was something even Gilgamesh dared not underestimate as he had before. Taigong Wang also stopped his frivolous talk and immediately activated the magic circle: "Thought Key Activation—"

The red magic circle enveloped the entire castle once again, but this time, it only lasted for less than three seconds before being shattered by the falling sun!

Fortunately, in those brief three seconds, Gilgamesh decisively retrieved numerous defensive Noble Phantasms from his collection. Combined with the defenses of Yggdrasil Castle itself, which had been transformed into Uruk Fortress and supported by the Greater Grail, he managed to block Karna's attack without serious damage, though the castle's outer walls were somewhat charred.

"Please let me fight against Red Lancer," Siegfried requested.

"Then it's up to you. Make sure that the Red Lancer can no longer pose a threat to the castle."

Makoto Aoki said decisively, "After all, Karna is really strong. After Scáthach injured her Spirit Origin in the battle against Achilles, Siegfried is the most suitable candidate."

At this point, I started to miss Mash and Achilles.

Makoto Aoki couldn't help but drift off for a moment; their Noble Phantasms were the nemesis of Karna's Spear of Godslaying.

Siegfried nodded slightly, then leaped down from the castle, using his fighting spirit to attract Karna's attention.

"The Black Coffin of the Eleventh, activate."

Semiramis raised her delicate hand, unleashing purple magic. The black magical coffin outside the Hanging Gardens activated, and beams of purple magic shot towards the castle, each one comparable to an anti-army Noble Phantasm.

"rider!"

Hachiman Hikigaya's palms were sweating.

"Understood!" Astolfo, mounted his eagle, shouted the true name of his Noble Phantasm, "Declaration of Logistille—"

The pages of the magic book in Astolfo's arms shattered and scattered in the wind, swirling around Astolfo and directly blocking one of the black coffin's magical attacks.

"A specialized Noble Phantasm against magic?" Semiramis said decisively, "Archer! Shoot him down!"

"understood!"

Atalanta drew her bow: "Polaris, shoot him down—"

Emerald magic, carrying arrows, shot fiercely towards Astolfo. The pink-haired knight screamed in terror, but the eagle flapped its wings and instantly teleported to the other side.

"Dimensional jump? A troublesome ability."

That being said, Atalanta fired a series of arrows, which at least distracted Astolfo, making it harder for him to defend the castle against Semiramis's black coffin attack.

Gilgamesh's face darkened, after all, he had been on the defensive the whole time.

"You lowly scoundrel!"

Gilgamesh raised his hand, and a stone tablet covered in cuneiform script appeared in his palm: "Alright, I'll take this one."

The numerous cannons placed on the city tower all started up silently, and the artificial humans diligently filled the "cannonballs" with them, their hands trembling.

These "cannonballs" are all genuine Noble Phantasms! They have never heard of such a thing before, that these extremely precious Noble Phantasms would be launched out of the wild as if they were consumables.

"Let me see if your Hanging Gardens are strong enough!"

Cuneiform script surrounded Gilgamesh as he unleashed his Noble Phantasm.
