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

"Awooo...wooo." Berserker made an ambiguous sound.

The Command Spell that Koles was about to use also stopped in mid-air: "I see, so this is your battle."

"So--"

Koles used a Command Spell again, but this time it wasn't to dodge, but to enhance it: "Fight with all your might, Berserker!"

"Ahhhh!"

With the Command Seal activated, Frankenstein went into a berserk state. Using her electrostatics abilities, she could discharge electricity almost endlessly. Under this full-force attack, green lightning enveloped the entire surrounding area.

"cut."

Atalanta was also struck by the spreading tree-like green lightning, and the originally fatal blow went astray. However, she was a battle-hardened hero after all, and she endured the numbness and pain brought by the lightning, running through the forest to create distance.

"Command Spells?" Atalanta felt irritated at the thought of her Master who never showed herself. Her eyes sharpened. "Then what will you do after the Command Spells are used up?"

Frankenstein's only response was attack!

"Ahhhh-"

Carrying the thunder of a thousand bolts, Frankenstein charged toward Atalanta.

After Atalanta lured Frankenstein away, only Rider remained to pursue Kairi Shishikage. Although Astolfo wasn't particularly motivated, he was still a Servant, and despite Kairi Shishikage's attempts to evade him, he was eventually found.

"Those who are far away hear my voice, those who are near see my figure. I am Astolfo, one of Charlemagne's twelve warriors!" Astolfo had never known what a surprise attack meant. In his opinion, using a sneak attack to target one's Master was simply too lame.

So, he could finally introduce himself properly and show off a little.

"Rider!" Serekine, who was retreating, was furious when she saw the Magic broadcast. She could have killed him in one blow, but now she had even revealed her real name. It was the most reckless thing she had ever done!

Especially with the head of the family, Danic, watching from the side, Serekine naturally understood his displeased gaze. If things weren't handled properly, she, as the Master, would also be punished.

"A mere familiar!" Serekine's face twisted in disgust.

"Can we make a deal? Let me go, okay?" Shishikage Kairi learned about Rider's personality from Hachiman Hikigaya and decided to give it a try.

"Eh? Well, actually I don't really care." Astolfo scratched his head, looking troubled. "Why was I summoned? But Master insisted on having me come..."

"Damn it!" Serekine on the other side was already furious. Her delicate face instantly turned ferocious, and intense hatred and jealousy twisted her whole body.

"In the name of the Command Seals, eliminate Saber's Master!"

Serekine used the Command Seal without hesitation.

"Damn it, I haven't finished speaking yet!" Astolfo's body stiffened instantly. He didn't attack immediately. Although he was a cavalryman, he had A-rank magic resistance, and a single command spell couldn't absolutely command him.

He warned, "Watch out, old man! I'm about to have to attack you!"

With that, he raised his lance and galloped toward Lion's Lair at an incredible speed.

"Command Seals? What a hassle." Shishikage Kairi didn't think he could fight against a Servant, so he simply used Taiko-no-Wang's one-time escape spell, which teleported him directly out of the battlefield.

"Huh? Gone." Astolfo lost his target and glanced around indifferently. "He's outta here, Master. This has nothing to do with me anymore." He was planning to hurry back and let the android escape.

"Such a good opportunity!" Serekine almost gritted her teeth. If Astolfo hadn't resisted and had instead used his Noble Phantasm, he would have definitely been able to take down Shishikai Kairi.

He must be punished! Serekine bit her finger.

King Arthur and Siegfried clashed again. Even though King Arthur had the numerical advantage, Siegfried made up for it with his superior martial arts skills. The two were so fast that only light and shadow remained, and two figures, one gold and one blue, were seen colliding wildly.

The two holy swords clashed in the air, and Siegfried's cooled blood gradually began to boil in the battle, his gray-green eyes regaining their luster.

"Hey, what are you doing?!" Gord roared angrily from the Yggdrasil Castle, watching the battle from afar. "Use your Noble Phantasm! You can't win this battle without it!"

"As long as we use that world-renowned dragon-slaying treasure, the Greatsword of Fantasy - Fallen Demon, we can surely slay the red dragon of Britain! Why not use the treasure, Saber!"

Gold already lacked trust in Ziegfeld, and the previous mission failure, which led to him being reprimanded by Danic, made Gold even angrier.

He's the Master!

"Is he enjoying the battle, just like before?"

"Is there no desire to entrust the Holy Grail to that familiar, and is battle the only source of joy for him?"

Gold's mind gradually became twisted. He could no longer tolerate that a mere familiar would disobey his orders and abandon the opportunity for victory because of its own pleasure.

He stubbornly believed that Siegfried would be able to win as long as he unleashed his Noble Phantasm, but he himself was unwilling to do so.

"How could we let you succeed? Victory belongs to Yggdrasilena!"

"I command you with a Command Spell, Siegfried, to use your Noble Phantasm to defeat King Arthur!"

Siegfried, who was fighting King Arthur, suddenly froze. King Arthur's holy sword slashed through his shoulder, and even with the protection of the Dragon Blood Armor, his skin was torn open and blood gushed out.

However, Siegfried merely trembled and stiffly raised his holy sword, Balmonk.

King Arthur hesitated for a moment, then did not take the opportunity to pursue, but instead retreated to create distance.

"O noble knight who sacrifices himself for others!" King Arthur knew the reason for the Command Seal and said frankly, "Fight me with all your might, according to your own will!" In any case, Siegfried was a respectable opponent, both in strength and character.

Siegfried's eyes flickered slightly. He understood what King Arthur meant. That's right, even if it was the Master's order, he was fighting King Arthur with his own will and determination at this moment.

King Arthur is a worthy adversary, and he must give it his all, even with the power of the Command Seals!

Therefore, Siegfried no longer resisted his Master's orders, but instead poured all his magical power into Balmmon.

"Sword, fill yourself with power." The hilt shifted, and the true ether stored in the blue gem on the cursed holy sword Balmonk began to unleash its true power.

"In the name of the Command Seal, Arthur, unleash your Noble Phantasm!"

Through the transmission of Taigong Wang's magic, Eriri also understood Arthur's determination, so now is the time! She used a Command Seal.

That's right, the blonde girl's eyes were resolute; no matter what, she would support Arthur!

Feeling the magical power emanating from his body, King Arthur's lips curled into a slight smile.

"Thank you, Master."

The two noble knights exchanged a glance and simultaneously raised their holy swords to their chests.

"Awaken from the golden dream, be freed from the cradle!" With the infusion of Siegfried's magic, streams of blue-green light shot straight into the sky above Balmonk.

"The thirteen constraints are lifted; the roundtable decision-making process now begins!"

Golden light rose around King Arthur, like the breath of stars, bringing a dazzling and awe-inspiring feeling.

"—Approved. Bedivere, Lancelot, Palamires, Gareth."

"The evil dragon will surely be destroyed!"

Siegfried gripped his sword tightly, his fighting spirit soaring.

"This is a battle to save the world!"

King Arthur solemnly untied the restraints.
