Simulate the universe, starting with speedrunning Greek.

He believed that as fellow magicians pursuing the path of magic, they would surely understand each other and become the best partners in that Holy Grail War.

Even Misaya of the Reirōkan is the prototype of Rin Tohsaka, so it wouldn't be wrong to say that the head of the Reirōkan is another Tokiomi Tohsaka.

however--

Since she is the prototype of Rin, although her personality is quite different after growing up, it is mostly because of the tragic experience in her childhood that she grew up wrong. At this time, Misaya is still very similar to Rin. She also admires her father and has the same drive, but she is not as arrogant and unreliable as Rin.

After overcoming her initial fear and curiosity, the little girl, now aware of the Holy Grail War, refused, saying, "No way! Beast wouldn't accept Daddy, would he? He seems to hate you. A good master-servant relationship is the foundation for winning the Holy Grail War."

As she said this, the little girl's eyes darted around and her face turned red.

No matter how mature she is, she's still young, and her mind isn't what it seems. Reiryuu-kan Misaya can't perfectly hide her emotions and thoughts; it's practically written on her face—'No, I don't want to give Beast to Daddy.'

Just like a child who gets a favorite toy, once they discover that the beautiful thing is not dangerous to them, their innate possessiveness makes them unwilling to let go.

And Misaya was right about one thing: even the head of the Linglong Pavilion realized, after being reminded, that she had been disliked by that Heroic Spirit.

It seems that's really the case... but why?

In terms of etiquette, he believed he had not done anything wrong. It was their first meeting, so why was he being disliked?

Before he arrived, the Heroic Spirit and Misaya seemed to get along quite well. Misaya had told him that he was an easy-going and gentle older brother.

"It's impossible that this guy is a loli Kong!" The owner of Linglong Pavilion's face darkened at this thought.

Considering that Rome and Greece are almost entirely related, and that Greek heroes in mythology all seem to have a certain—well…

He recalled how his daughter had spied on him from time to time before, and how he had only spoken up to interrupt the process. He also remembered how his daughter was now defending her sovereignty in front of him, blushing and looking around as she tried to keep the subject in his hands.

A not-so-pleasant feeling arose in the mind of the owner of Linglong Pavilion, hoping that his overly dangerous thoughts were just an illusion!

Just then, the barrier in the annex sensed someone's approach. The head of the Reiryukan immediately went on alert. During the Holy Grail War, vigilance was paramount at all times, especially since Misaya had suddenly become a participant. As her father, he had been completely unprepared for this, and the Reiryukan family's resources had not yet been mobilized. At this vulnerable moment, if they were attacked—

“Misaya—be ready to call the beast back at any time, and use Command Spells if necessary…” The head of the Reiryukan decisively said. After receiving her daughter’s response, she began to observe the outside world through her familiar.

At this moment, three figures, one large and two small, appeared in the eyes of the owner of Linglong Pavilion.

"Hiroki Sajou?" In the original story, the head of the Reikoku-kan family and the head of the Sajou family knew each other and were ordinary friends. Their relationship was very similar to that of the three main families in the neighboring Fuyuki City. As magical families in Tokyo, they naturally had frequent interactions with each other.

At this moment—the two figures following Hiroki Sajou were naturally Aika and Ayaka.

Seemingly noticing the familiar's gaze, Sajō Aika suddenly turned her head and looked over, revealing a perfect, radiant smile on her face. She gracefully lifted her skirt and bowed, saying, "Greetings, Uncle Reirō-kan! Please don't be so wary; we've come here specifically to form an alliance."

……

Meanwhile, in Germany, far away in Europe, the Einzbern family, having suffered another defeat in the Third Holy Grail War, began to consider seeking outside assistance.

In order to fulfill their family's long-cherished wish, the Einzbern family, one of the three founding families, abandoned their honor and shame and invited the infamous magician killer, Kiritsugu Emiya, as their accomplice, hoping to help the Einzbern family win the Holy Grail War by hiring this man.

Having learned what a miraculous existence the Holy Grail truly is, the man who has dedicated his entire life to the ideal of 'creating a world where no one cries' finally sees a way to fulfill his tragic wish.

"To be a partner of justice!" This wish of an executioner who roams various battlefields is a world peace that even a child would laugh at. The more darkness he witnesses in the world, the more powerless he feels. The power of an individual is too weak. Even if he tries his whole life, he could not possibly save all mankind.

Unable to devise a way to achieve world peace using his limited human brain, Kiritsugu Emiya places his hopes on the Holy Grail, believing that if he makes a wish, the Holy Grail will surely respond to him.

Unfortunately—if he could hear the conversation that a certain Demon King had just had with Ye Su, he would surely understand that it was impossible.

Just as an era of mutual understanding between people will never come no matter what!

Chapter Sixteen: Truth and Falsehood, Even if it's a fake Command Seal, so what? For the world.

However—regardless of the fact that he is a stubborn man who will not turn back until he hits a wall, even if someone tells him that the Holy Grail is full of black mud and can no longer be used, he will insist on seeing the black mud before he believes it.

Furthermore, the Demon King would never pay attention to such a boring fellow; many tragedies—such as killing his father, his childhood sweetheart, and his mother—were caused by his own hands.

In Shan Shan's words, it's hypocrisy.

To satisfy one's selfish desires (to save the world), one could also ruthlessly wipe out all of humanity.

Having no idea of ​​Kiritsugu Emiya's true nature, the Einzbern head—Ahad, as the clan patriarch—attempts to bind him to his own chariot through a marriage alliance.

However, this man could not possibly be bound by so-called blood ties, kinship, or romantic relationships and give up his 'grand ambition'.

Ahad, who was destined to end up with nothing, was just chatting and laughing with Kiritsugu Emiya about a cooperation agreement when, upon receiving some news, his expression changed, and he suddenly changed his mind and asked Kiritsugu Emiya to leave the castle.

...His attitude was extremely firm, and no matter how much Kiritsugu Emiya pleaded, there was no room for him to change his mind.

When they came to their senses, the man, his face dark, was already standing alone on the snow outside the castle.

Suppressing the urge to pull out the Origin Bullet and storm into the castle to fire a few shots at those damned homunculus, Kiritsugu Emiya felt as if a million alpacas were galloping through his mind.

He tossed the cigarette onto the snow and stomped it out—Emiya Kiritsugu couldn't help but mutter, "What on earth happened?... What's going on? That Ahhadon suddenly unilaterally terminated the employment."

I'm not reconciled, I'm so incredibly unwilling!

Suddenly, they called him over, gave him hope, and let him know that there was such a thing as the Holy Grail, an all-powerful wish-granting machine that could grant all desires. They showed him an opportunity to fulfill his ideals and tragic wishes, and then suddenly took it upon themselves to kick him away.

If he had never known of the Holy Grail's existence, he might have been able to endure the darkness. But for Kiritsugu Emiya, who had already made up his mind that no matter what, even if it meant being shattered to pieces and sacrificing his life, he would hold up the Holy Grail himself and make a vow for world peace before he died, he felt as if the sky had fallen, and he was filled with utter despair and helplessness.

"If I can't become the Master of one of the three starter families, I can only try my luck and see if I can be chosen by the Holy Grail..." Kiritsugu Emiya gritted his teeth.

But the probability is too slim. Seven people are selected from seven billion to participate, and three of them are already pre-selected. Can his obsession and desire for the Holy Grail really be answered?

Rather than accepting a slim chance, he preferred to play it safe and qualify for the competition in place of one of the three starter families.

Apart from the Einzbern family, which is willing to disregard the reputation of magician families in order to achieve its long-cherished wish of the Third Law, the other two families are unlikely to ask for outside help, let alone ask him, a notorious magician killer, to be their helper.

Having lost the resources of the three starter families, he would find it difficult to find good relics and summon powerful Servants with his own wealth. This is why Kiritsugu Emiya pleaded so desperately with Ahadeon, even willing to give up his dignity. However, the old man was quite unreasonable.

What exactly happened to cause such a drastic change in their attitude?!

"Is this the only option to try my luck in Fuyuki City?" Just as he was thinking this, suddenly—Emiya Kiritsugu felt a sharp pain on his neck.

He was jolted—his pupils contracted—and then he felt a new message in his mind, finally understanding what had happened.

At this moment—beyond Kiritsugu Emiya's sight—a bright red Command Seal, resembling an angel's crest, appeared on his neck.

Unlike the Command Seals of the regular Holy Grail War, this was a Command Seal system hastily drafted and forged by Ayaka Sajō, a fake Holy Grail War authority, however—when it unfolded at a similar time to the real Holy Grail War.

A unique clash occurred between the real and the fake Holy Grail War, a faction war between the genuine and the counterfeit, and new rules of the Holy Grail War naturally emerged.

At this moment, because of Kiritsugu Emiya's exceptionally strong will (a demonic spirit) that is rare among all of humanity, he obtained the Command Seals for the Pseudo-Holy Grail War, even though he couldn't obtain normal Command Seals from Fuyuki, who was far away.

A battle between real and fake Heroic Spirits in 7v7, and after the winner is determined, the 7 members inside decide the true victor to hold up the omnipotent wish-granting machine that can grant any miracle!

This is a war to defend the real war, but it is also a war that can usurp the real war.

Even though it's a Command Seal from a pseudo-Holy Grail War, it's still a qualification to participate! With this in mind, Kiritsugu Emiya hardened his gaze. Although the battle between 7 pairs of Master Servants had become a battle between 14 pairs of Master Servants, it had obviously increased the probability of winning the final victory.

But Kiritsugu Emiya had no intention of backing down.

This may be his only chance; he has no time in his limited life to wait for the next Holy Grail War.

He must—achieve final victory in this great battle between 14 pairs of Master Servants!

That's right! In Kiritsugu Emiya's eyes, it's a battle between 14 pairs of master and servant. In essence, even among the Servants on the same side, a final victor must be chosen to lift the Holy Grail.

Only one person can make a wish. As long as this fact and premise remain unchanged, both the opposing camp and our camp are 'enemies'. The only difference is that one is an open enemy and the other is a potential enemy.

If given the right opportunity, Kiritsugu Emiya would not hesitate to betray his own teammates.

Thinking of this, Kiritsugu Emiya wholeheartedly prepared to leave this place and seek some mysterious guidance, knowing that his teammates would all gather in Tokyo.

If Ahadron discovers that I am a fake Master, then we're doomed.

He must escape from here immediately!

Hoping to obtain some rare and better 'relics' from his so-called allies, Kiritsugu Emiya has once again set his sights on his teammates.

Since he can't find good artifacts, his teammates might have some. Borrow artifacts from a teammate, summon a powerful Servant, and then use the Servant summoned by the artifact given to him to backstab the opponent!

Even if it's not the strongest Heroic Spirit, it's still better than him, a self-taught individual, creating his own relics. He should find the right opportunity to use their strength against them while simultaneously targeting the stronger side from behind—weakening both sides will eventually create an opportunity for him to win!

He had long possessed this level of indifference and ruthlessness, but the next moment, a summoning circle suddenly lit up.

Emiya Kiritsugu: "!? What's going on! I definitely didn't..."

Meanwhile, on the other side, in the Grand Temple of Time, a demon king named Goetia, who was ready to learn the ways of the night and use a 'disguise' to bypass human reason and descend into that world, then opened his eyes after choosing a 'tool' Master.

Chapter Seventeen "We won!" xN, I'm sure! Night: ? Dare you say that again to my face?

Seven days—the same time it takes for Noah's Flood to descend after Gilgamesh's Noble Phantasm analyzes the laws of the present world.

This is the time for destruction, or it can be the time for salvation.

After leaving the Linglong Pavilion at night, he did not actually leave. Instead, he went to the roof of the Linglong Pavilion and unleashed his domineering laws. Based on the current strength of his will, it would take about seven days to complete the outflow and coverage of the law.

The more powerful a Noble Phantasm is, the more demanding the conditions for its use are. Just like the old Dodge Summoning's Napishtim's Rage - a flood that almost submerged Tokyo and spread globally, or the old Saber's one-shot attack that unlocked all seven permissions after fulfilling the conditions for saving the world, allowing the Holy Sword to unleash half of its restrictions for star-level output as long as the conditions for saving the world are met.

Of course, none of these Noble Phantasms can compare to Night's, and Night's Noble Phantasm is certainly not comparable in scale to the one she originally possessed in Norse mythology. Rather, it is Night's Noble Phantasm that materialized after she became a Heroic Spirit.

'Flow' – After analyzing the laws of the world over seven days, its surface will be covered with its own colors and rules. At that time, the power of the night will reach its peak, and no one will be able to stand up straight and speak before the night seven days later.

Of course—even now, few Heroic Spirits can withstand Night's power, let alone rival it. To survive three moves against Night is at least the level of a first-rate Heroic Spirit.

And it was during the preparation of this great treasure that Night was able to spread her perspective and feelings to every corner of the planet through the diffusion of her will, achieving a full-map strategy without blind spots or dead ends, plus real-time communication!

This alone is already a decisive factor in the Holy Grail War.

No one's little tricks can escape his eyes in the sky. There is no escaping it. Even those who are capable of noticing this can only endure being exposed to his will every day as if they were naked and defenseless—an alternative form of 'I am the only one who reigns supreme in heaven and earth'.

And it was under this power, and under the deliberate control of the night, that he first observed the territories of his old acquaintances in the Holy Grail War—the three starter families.

At that moment, he happened to witness everything that was happening in Einzbern, Germany.

……

"Heroic Spirits"—their autonomy was summoned.

Despite having no artifacts and no intention of summoning as his Master, the light of summoning immediately shone forth.

Kiritsugu Emiya's expression turned grim.

If there are no artifacts, then it's all about 'affinity summoning'. Right now, all we can do is hope for an obedient and useful support character like an Assassin.

For someone like Kiritsugu Emiya, who enjoys using any means necessary to eliminate his enemies, drawing an Assassin-class Servant would be the best solution in his mind—to directly lead his Servants to assassinate all Masters.

After all, no matter how powerful a Heroic Spirit is, the magician who serves as their Master is fragile. Once the magician is eliminated, even the most powerful Heroic Spirit is nothing more than a toothless tiger.

If we were to say that among the seven classes, the Assassin class is what Kiritsugu Emiya desires the most, then the Caster class is probably what he least desires.

After all, magic is extremely expensive and resource-intensive, and given Kiritsugu Emiya's personality, it's impossible for him to simply set up a magic workshop with his Servants and hide away.

Just as Kiritsugu Emiya was praying in his heart that he would accept any class as long as it wasn't Caster, he was still praying.

However—the next moment, as billowing dry ice smoke rose—a majestic yet indifferent, magnetic voice of a wise man rang out: "Caster—!"

The fact that Kiritsugu Emiya revealed his class so soon after he opened his mouth made his expression even more unpleasant.
