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

A torrent of golden light clashed with a blue-green sword aura that shot into the sky. Both sides poured their will and determination into the attack, and the violent magic destroyed the land between them.

The two torrents of magic canceled each other out and suppressed each other in mid-air, and the magical elements in the air forced the nearby Servants to retreat.

In the end, the magical torrents of the two Noble Phantasms even intertwined, causing a massive explosion that shattered everything around them.

After the loud noise subsided, only two people were still standing.

King Arthur lowered the tip of his sword, and Siegfried on the other side did the same.

Their turquoise eyes met each other's grey-green eyes.

Tie.

The two fought to a standstill.

If King Arthur's sword were to truly unleash the power to cleave two planets, Siegfried would naturally be no match. However, currently, his sword has only broken five seals. Both swords are empowered by Command Seals, both are dragons and dragon slayers, which negates all their advantages.

Even the slightest difference in the distance would result in almost no injury under the protection of Avalon and the Evil Dragon Blood Armor.

"It is truly delightful," King Arthur exclaimed. "It is a privilege to fight alongside you with all my might."

"...I feel the same way. Thank you for fighting me with all your might, King Arthur." Siegfried still admired King Arthur, even though he lived after him. King Arthur was known as the King of Knights.

In this battle, the opponent's noble character and formidable strength were also clearly revealed.

"...So you're withdrawing now." King Arthur smiled slightly, pretending to listen to something. "It seems that this time the outcome is still uncertain. Then let's leave the victory to the future, Siegfried."

"We'll settle this another time, King Arthur." Siegfried's usually gloomy expression finally brightened somewhat. Even if he and his Master couldn't understand each other, fighting against such an opponent and answering the call of this Holy Grail War was not meaningless.

King Arthur glanced back at the suddenly rising magical power in the distance, then vanished in spirit form.

He still needs to find the retreating Lion Jie Li, who has escaped from Rider's pursuit. He must not get hit by the map attack.

"Should we retreat?" Atalanta also received Kotomine Shirou's order and felt Spartacus's rampaging magic. To be honest, after getting carried away with the fight, she forgot that her original goal was just to stall until Spartacus unleashed his Noble Phantasm.

"Let's stop here." Even as a Heroic Spirit, Atalanta was exhausted by the chaotic battlefield, not to mention that the two Sabers had even unleashed their Noble Phantasms. For a test, their actions tonight had far exceeded expectations.

"Let's settle this another time, Black's Servant." Atalanta left these words behind and quickly disappeared into the forest.

"The eldest sister has retreated."

Achilles was still struggling to dodge the arrows of the black archer. He didn't know that his opponent was his teacher Chiron. He only knew that his movements were completely seen through, making his fight extremely frustrating.

Even so, Achilles tried his best to attract Chiron's attention, often running to other battlefields to interfere with the attacks of other Black Faction Servants, forcing Chiron to control him to the maximum extent possible, making it difficult for him to affect other battlefields.

"Then there's nothing more I can do." Since Atalanta has left, Achilles certainly won't stay and fight to the death. With Archer capable of piercing his defenses, Achilles isn't so reckless as to think he can kill seven people at once.

However, the fighting spirit and joy rising from the depths of his heart made him burst into laughter.

"Hmph hmph hmph, hahahahaha—"

Unlike other Servants, Achilles participated in the Holy Grail War and answered the summons precisely to enjoy the battle.

He had no desire for the Holy Grail; he only came to fight against heroes from all ages.

"Isn't this wonderful? Black Archer!" Achilles said magnanimously. "Fighting someone as capable of killing me is fate. Since we are destined to be together, we should fight each other to the death!"

As he spoke, he turned his head to dodge the incoming arrow.

"O Olympian gods, bestow glory and honor upon this battle!"

He whistled, and his own "Undying Chariot of Gale and Raging Waves" was summoned. He no longer concealed his real name, but instead openly rode away in the chariot.

"Let's settle this another time, and I'll see what you're made of!"

Having left behind the challenge, Achilles rode away in his chariot, leaving only a magical afterimage in the air.

How ironic, Achilles, that fate sometimes bares its fangs at us, the dead.

Chiron slowly relaxed and released the drawn bowstring.

However, he also knew very well that even if they knew the other party's identity, neither Achilles nor he himself would hesitate in the slightest.

Their only destiny is to fight each other.

"Chiron?" Fiore asked with concern.

“Master,” Chiron’s clairvoyance spotted the berserk Spartacus, “it seems we need to deal with this Servant first.”

"O oppressor, I will crush you!" Spartacus charged forward fearlessly, his bulky body smashing through many pillars. "I will never condone the strong oppressing the weak!"

“For the first time, I have felt respect for a traitor,” Vlad III remarked, but he did not hesitate for a moment as he continued to attack with the stake. Killing a traitor was, in itself, the greatest respect that a warrior could give.

Countless stakes shot up from the ground, forming a torrent that hurtled towards Spartacus, instantly turning him into a pincushion.

They were completely powerless to fight back, but is that really the case?

"Oppressor!" Spartacus was utterly fearless. His eyes and his will were fixed on Vlad III. He had to defeat the oppressor and save the oppressed weak!

His already bloated body transformed into a ball of flesh, with eerie eyes and a mouth full of sharp teeth appearing on it: "Let me destroy you with love, oppressor!"

The rapidly expanding magical power caused Vlad III to wear a solemn expression: "Give me the piercing power of the Pillar of Despair..."

"—King of Extreme Execution!"

When Spartacus was released, countless stakes that had been embedded in his body pierced his massive form a second time. Logically, this should have damaged the Servant's core and forced him out of the game.

After all, given the chaotic situation, Vlad III had given up on transforming Spartacus; in any case, reducing the strength of the Reds was not bad.

Spartacus did not stop. His body was pierced again, but he used the endless damage to undergo another transformation. All the damage was stored in his body, and at this moment, his body swelled up again and even began to crack.

Vlad III wore a grave expression. He knew that his Noble Phantasm would be insufficient to deal with this situation, and the Executioner would only make things worse, failing to eliminate Spartacus in one blow.

"Danick." A true hero-king knows how to utilize the power of his subordinates.

“As you command, Your Majesty.” Darnic had already retreated to the castle. To prevent Spartacus’s attack from affecting his own position and other Servants, he commanded Gordes, “Use Command Spells to have Saber unleash her Noble Phantasm at full power and vaporize Berserker!”

Despite his dissatisfaction, Gordes could not disobey Darnic's orders, so he used the Command Spell again: "Use your Noble Phantasm with all your might against Berserker, Siegfried!"

Siegfried's expression was solemn as he raised the holy sword Balmongk high, its blue-purple sword energy piercing the sky.

"My strike will shatter all suppression—"

"The evil dragon has fallen, and the world is facing its twilight."

"Crying Warmonger!!"

"Fantasy Greatsword: Balmung - Fallen Demon!!"

After the sword strike, Spartacus was never seen again.
