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

Amakusa Shiro Tokisada, the leader of the Shimabara Uprising and the ruler of the Third Holy Grail War, successfully remained in the real world for sixty years after Darnic seized the Greater Grail. In pursuit of his distant dream, he adopted the alias Kotomine Shiro and participated in the Holy Grail War as the superintendent of the Holy Church.

After all, he is not the ruler of this Holy Grail War. He has lost most of the privileges that belong to the ruler, but even without being crowned, he is still a saint.

In other words, he has an A-level "revelation" that allows him to see visions of the future.

This ability is passive; Amakusa Shiro Tokisada can only learn about the future by capturing and analyzing images of the future.

At that moment, he instinctively pressed his forehead against the ground.

He saw fragments of the future, Black Faction Servants, and even Red Faction Servants, battling with unfamiliar Servants.

what is this?

Amakusa Shiro Tokisada staggered slightly.

"Master!" Semiramis supported her master with concern. "What happened?!"

A deep purple array appeared beneath her feet, and the black queen flew into a rage, seemingly wanting to tear the unknown attacker to pieces immediately.

"No, it's my own problem."

Amakusa Shiro Tokisada instinctively gripped the cross on his chest: "It was the Lord who gave me this revelation."

"There may be outsiders interfering in this Holy Grail War." Amakusa Shiro Tokisada confirmed that the strange Servant in the revelation was not just one person, and that all the Servants had already appeared.

"An outsider? Who is it?" Semiramis knew Amakusa's abilities well, and she actually trusted him a lot. "Will they interfere with our plans?"

“I really hope this is just my imagination, but perhaps this is what I’ve always felt was out of place. Rider and Archer are back, aren’t they?” Amakusa Shiro Tokisada said calmly. “Let’s see them first. Perhaps we’ll need them to make another trip.”

……

"Huh?" Achilles picked at his ear. "We have to go to the Black Square to investigate again?"

"Hey, we just got back and haven't even had a chance to catch our breath yet." Achilles crossed his arms. For him, the point wasn't about making another trip, but about being ordered around by irrelevant people.

“Father,” Achilles said arrogantly, “you need to understand that you are merely our agent, not our Master. You have no right to command us.”

“That’s right,” Atalanta also stated her position. After all, the fact that Shishikage Kairi fought alongside their own servants made both her and Achilles dissatisfied with their sneaky Master. “If you want to give us orders, then let the Master do it himself.”

And it's strange.

Just as Achilles had his suspicions, Atalanta also felt something was amiss.

Even if a magician likes to hide, it's not like they wouldn't show their face even once after being summoned.

"You guys!" Semiramis's expression turned hostile. Achilles and Atalanta's defiance of Amakusa Shiro had greatly displeased her. A deep purple aura of magic emanated from her body, and she was ready to strike at any moment.

"Bring it on!" Achilles drew his meteor spear, completely unafraid.

Amakusa Shiro Tokisada stopped Semiramis's actions, remaining calm as he asked the last Servant present, "Lancer, do you think so too?"

Karna, with his white hair and golden armor, said calmly: "Since Master has commanded me to obey your orders, I will follow your commands until the orders are changed."

“Hey, Lancer! Don’t you think this is suspicious!” Achilles was indeed a warrior, but as a hero who shone brightly in the Trojan War, he was by no means a reckless fool.

His suspicion of Shiro Kotomine is the reason why he is unwilling to compromise easily.

"If someone absolutely has to be sent to investigate, why not send Assassin? With his Presence Concealment ability, Assassin is the best candidate. What exactly is your purpose in constantly ordering us around like this?!"

Compared to the dialogue in the original work, Achilles's is now a bit sharper.

"You rude fellow!" Semiramis, with her strong sense of pride, could not tolerate such provocation. Dark chains, shimmering with deep purple light, burst forth from the magic circle behind her and attacked Achilles.

"Well done!" Achilles was not afraid at all. With the help of the comet running technique, he instantly became an invisible afterimage and easily deflected Semiramis's attack.

The two clashed in an instant. Atalanta drew her bowstring, the arrow pointing at Semiramis, clearly demonstrating her stance.

Faced with the imminent split of the Red Team, Amakusa Shiro Tokisada remained calm and composed. He looked at Achilles with gentle and serene eyes, preventing the split from escalating further: "If we fight amongst ourselves here, that's not the kind of situation you want to see, Rider."

“Then give us an explanation we can accept.” Achilles didn’t really want infighting, after all, he hadn’t yet decided the victor against the Black Archer, but as a hero, he also had his own pride.

"I see. I'm sorry, that was my oversight. Even if we need to keep key information confidential, communication is still necessary."

Amakusa Shiro's unhurried voice and peaceful demeanor effectively eased the tense atmosphere: "Assassin has been stationed here not to avoid battle, but for a more important reason: to prepare for our attack."

"Oh? You actually built a castle and made preparations to defend it?"

"Hmph, hold the city?" Semiramis stood arrogantly on the throne, looking down at Achilles. "Don't judge my actions by your own standards, Rider."

Amakusa Shiro Tokisada smoothed things over, saying, "Before we prove ourselves, let's welcome the last member."

"Oh, in your hellish, pitch-black night, I find you so beautiful, even radiant! The End."

The visitor gave an exaggerated bow.

Then, he looked at the current situation and raised his eyebrows: "How tragic! Before the magnificent Holy Grail War begins, our side has to engage in a duel of heroes. What a dramatic scene!"

"Of course, please forgive me for remaining neutral. After all, I am not very good at magic or combat; I am just an ordinary writer." The man rubbed his fingers together, not ashamed but proud.

“Caster,” Semiramis narrowed her beautiful eyes, “can I take that as a provocation?”

"No, no, no, how could that be, the Assyrian Empress!" The Red Team's Caster, the world-renowned writer Shakespeare, waved his hands repeatedly. "I will record this heroic battle and watch over it all!"

"After all, I can't record my own story; I only have the ability to weave the stories of others."

"Moreover, I must witness the end of the Holy Grail War; this is the mission we have been given!"

Semiramis rubbed his forehead, feeling a bit of a headache. To be honest, Shakespeare's words had almost completely ruined the tense atmosphere that the Red team had been maintaining.

"Anyway, everyone's contracts have expired now, Rider, open your eyes and take a good look."

Achilles shrugged indifferently.

"Hmph, this is a rare Holy Grail War, so let's make it even more spectacular."

Semiramis gave Achilles a cold glance and activated her Noble Phantasm.

"Let me show you the heavenly fortress, a place no human can reach. The Gardens of Vanity, the Hanging Gardens of Babylon!"

Accompanied by Semiramis's words of liberation,

"So, do you still have any questions now, Rider? Assassin's abilities require her to be stationed in the Hanging Gardens to reach their full potential."

"Are you willing to be a vanguard in this battle? Of course, we will follow closely behind."

It wasn't reconnaissance, but a full-scale battle, so Achilles naturally had no reason to refuse.

"I can't ask for it!"

Like a shooting star, a streak of light hurtled towards them. Achilles mounted his chariot and headed straight for the Black Faction Castle.

"Then I'll go ahead too." Seeing this, Karna, who could fly anyway, simply followed Achilles away.

"These two guys."

Atalanta was a little annoyed, but what could she do when she couldn't fly?

"Wake me up when we get there." After saying that, Atalanta transformed into her spirit form. After all, she had just finished a battle. Even though Servants don't get tired, not everyone is as energetic as Achilles.

"Then we shall take our leave, so that we may better record this epic moment!"

Even the master of slacking off, Shakespeare, has slipped away.

Only the Empress, sitting aloof on her throne, and her Master remained.

"Is it really okay to bring forward the final offensive, which was originally scheduled for tomorrow, to today?"

“But we have no other choice, do we, Assassin?” The white-haired priest said serenely. “I have a feeling that if we miss today, there will be no chance of victory.”

“I thought you really didn’t care,” Semiramis chuckled.

“If I am attacked, it proves that I have disobeyed the Lord. I will quietly await death, and there is nothing I can do about it.”

The nameless saint of the Far East, Amakusa Shiro Tokisada, gripped the cross on his chest.

"However, I will not give up any possibility of victory. If I can succeed, it will prove that the Lord has forgiven what I have done."

"That proves that my desire to extend mercy to all mankind, to heal all mankind, and to desire the Greater Grail is absolutely correct."

"Once I understood this, I had no more confusion."
