Simulate the universe, starting with speedrunning Greek.

Even Saber, with her extremely high level of magical resistance, had to struggle a bit under Kiritsugu's Command Spell and give him some face.

Gilgamesh was caught up in the action when Tokiomi forced him to retreat mid-game.

C's mother also needs to use the Rule Breaker to poke herself to break the contract in order to avoid the power of the Command Seals.

Only the night—his will was absolute and unshakable.

If there is no magic that can influence the entire universe, such as the power to shake the dominant laws (willpower) of an equal universe.

This is a conceptual absolute defense.

However—just as Ye was about to step into the passage, an unexpected event occurred.

What was originally just one channel for summoning the night suddenly saw countless other channels crowding in, with countless summoning messages rushing in, like the eager gazes of a pair of fiery, infatuated women.

night:? ? ? !

What's going on (ghost)?

Chapter Seven: The Man Who Almost Cut Off His Own Finger in a Moment of Excitement!

Legend has it that he was a hero who loved everything, the Adonis of spring, who, during the Trojan War, donned the armor with unparalleled bravery that no one but the swift-footed Achilles could wear.

He defeated Hector, the most famous and strongest hero of Troy at the time, and the Amazon queen, daughter of the god of war.

To fulfill his promise to return his armor to his friend, and to better align with that power, he forcibly ripped the armor from his body, even though it was already intertwined with his flesh and blood. With that bloodied body, he protected the princess of Troy, fought his way through countless heroes, and even defeated Poseidon, the god of the sea, and Ares, the god of war.

Legend has it that he was a demon king who destroyed everything, returning from the abyss of the underworld, scorching the sky and shattering the earth, once causing Greece to nearly perish as a civilization destroyer. He was the only king to have unified all of Greece, defeated by the Holy Sword and Holy Spear of the Star, with the help of heroes from all of humanity.

No one expected that these two people would end up being the same person.

He loved everything, yet he destroyed everything; because of 'love,' he became 'evil.'

However—more than these stories, few people know that he also left behind profound legends in another world.

however--

“I know…Aika knows everything—! The dragon-slaying hero of Norse mythology, the handsome and beautiful prince of the Volsung family! The Demon King who raised the banner of ‘absolute evil’, deeply loved humanity, yet was forced to become the enemy of all mankind.”

Although the world is different, the myths are all the same.

Even in the lunar world of Northern Europe and Greece, there are still records of all kinds of stories about the night, and therefore those things that have not yet been proven or confirmed.

For the Root Princess, who can understand everything directly from the source and intuitively understand all the 'truths' from God's perspective, she can easily know everything she wants to know, including the fact that the two world-famous heroes in Greek and Norse mythology are actually the same person.

This world is so boring!

He knows everything from birth, although his talent as a magician seems poor, possessing only one magic circuit.

However, the quality level of this magic circuit is the highest, the extra-extraordinary level.

It is because it connects to the legendary origin, the end of all mystery, the other shore that magicians throughout history have been searching for, yearning for but unable to reach, a miracle that remains in the real world.

Even in the Holy Grail War world where this girl appeared, Caster, who possessed unparalleled magical talent and was extremely famous in both the academic and magical worlds, the legendary doctor and alchemist von Hohenheim Paracelsus who was active in the 16th-century Renaissance, only met this girl once before choosing to betray his Master without hesitation and join her ranks.

The original Von Horn Zero Heim Paracelsus got along very well with his Master. There were no conflicts when they first met. He even became good friends with the head of the Reikoku-kan, a junior in the magic world who greatly admired him.

Throughout this process, the affection between the two was genuine.

However—"Magicians have no true friends," he sighed, as he encountered Aika Sajō, whose very existence symbolized the "truth" she had been searching for her entire life.

Without hesitation, von Hohenheim Paracelsus betrayed his Master and cursed his beloved daughter, Reirōdō Misaya. He then used these words to teach Reirōdō Misaya a lesson, leaving her with a profound and painful understanding of the obsession of magi in her childhood—one of the Masters of the Fifth Holy War in a parallel world.

Sajō Aika, who is connected to the root of all things, is truly a darling of the heavens. She can get whatever she wants and do whatever she wants with ease. Even if it's something that doesn't belong to her, she'll just take it away.

It could even be said that he directly possessed administrator privileges and the world script, personally descending the mountain to crush everything, much like the author himself.

Omniscience from birth—in the world of gods, this is a blessing that is like being born a god, yet also tormented by an endless sense of knowing everything, by the constant torment of this boring life.

In such a boring world where one knows the end from birth, knows everything about life, one cannot even develop a personality.

In the book, it is described as a pure, flawless blank sheet of paper.

Therefore, she sealed off most of her perspective shortly after birth, pretending to be a normal person, a girl who grew up without emotions, hoping to pursue some unknown aspects of life and bring herself some fun in the process.

She stopped her ability to easily see into the future.

Just like how Gilgamesh sealed away his omniscient and omnipotent star, and his far-seeing eyes.

A world that is too transparent is simply uninteresting.

Finally—under these circumstances, the timeline of the Old Sword world was born.

When Ayaka Sajou summoned a Heroic Spirit, it was not the kind of Heroic Spirit she had expected or preferred.

According to the original description, she preferred a taller, stronger, and wilder type of Heroic Spirit, rather than a white-horse prince-type knight like Old Saber who, despite having the name of a bear (the King of Knights is a symbol of the bear in mythology), had a completely handsome face.

Because this summons did not meet her expectations, she felt a great deal of 'unknown'. Emotions and feelings that she had never been satisfied with for more than a decade poured out at that moment, becoming uncontrollable in their fervor, joy, and obsession.

At that moment, Aika Sajou finally developed something called 'personality'.

This led to what she considered a 'romantic comedy,' but in reality, it was the beginning of a tragic and ill-fated relationship.

However—in a world where fate is already predetermined, seeking the unknown… is inherently a contradictory act.

If you think about it carefully, the reason she couldn't summon the Heroic Spirit that matched her initial expectations might also be a pre-arranged drama she had prepared for herself.

Because of her yearning for the unknown, it responded to her heartfelt desire, using more than a decade of known knowledge to create an unknown for herself.

But when this toy is confronted with the appearance of the 'unknown' that truly transcends this world, it becomes worthless.

...The anomalies that occurred at the source of countless universes, caused by the moment when the night broke through the world and entered another world, naturally also affected this Root Princess.

This astonishing situation caused a strange fluctuation to flash in the eyes of Ayaka Sajou, who was originally pretending to be a good girl and maintaining her 'doll' persona at home while cooking for her younger sister. She even cut her finger while chopping vegetables and almost chopped it off in a fit of excitement.

...Blood flowed from the broken skin of his finger, yet he seemed completely unaware of the pain.

Chapter Eight: Why don't all those "me"s just die! Very well, time to research how to destroy parallel universes.

If Ayaka Sajou, Ayaka Sajou's younger sister, saw this scene, she would be absolutely stunned.

My older sister, who has always been perfect at everything she does, actually made such a serious lapse in concentration and mistake that almost cut off her finger.

Sajō Aika is absolutely right, an absolutely perfect being!

It's not a persona, but true perfection. This is something that her younger sister, Ayaka Sajou, who grew up with her, and her adoptive father, Hiroki Sajou, have both been certain of since her birth, and it's something that time has witnessed.

She loves songs—she can do everything perfectly!

She didn't live like a human being, but rather like an absolutely perfect machine, an absolutely perfect, flesh-and-blood, breathing doll.

However—as it turns out, love songs are not perfect.

She also has aspects that excite and break her defenses.

No matter how calm he tried to appear on the outside, he couldn't hide the restlessness in his heart. His eyes burned with an intense intensity, as if something was raging within them.

Sajo Aika took the initiative to unseal the long-sealed link and reconnect with the root.

She was very curious—what exactly had caused the source to change?

This was something that should never have happened!

Until—from the records at the source, they gained a perfect understanding of everything that had happened outside the world not long ago.

Thus, upon witnessing that 'humanoid' descend upon Valhalla, Aika experienced an unprecedented and intense emotional upheaval.

In this intense urgency, like land parched for a long time, like a dying person desperately thirsting for rain, a strong possessiveness is also born.

'who is he?

Having developed such an urgent desire for answers, Ayaka Sajou, tracing back to the source, quickly learned everything about that hero and his magnificent life.

And that piece that seemed to have been missing before his arrival in this world—now, it has finally awaited the return of this divinely gifted hero! The most crucial piece of fate's puzzle has finally returned!

Everything about this hero's return is full of exploration.

It's even more profound than love at first sight!

After all, for other living beings and for other women, there is a possibility of falling in love at first sight with any handsome stranger.

But for Ayaka Sajou, there was only one 'stranger' in this world who was worthy of her love at first sight.

then--

That night, as preparations were underway to respond to the coming of the subspecies Holy Grail War.

Upon learning that Yoru was to participate in the Holy Grail War as a Heroic Spirit, Sajō Ayaka exploded...!

That subspecies Holy Grail War didn't seem to happen in her world, so how could she watch that glorious hero fall into another world?

And so—Sajō Aika, who was preparing to intercept the prize without hesitation, had her wish fulfilled, and a bright red Command Seal mark immediately appeared on her chest.

Compared to that fat guy next door, a beautiful girl like her is definitely more attractive to heroes, right?

Making that fatso the Master is such a waste!

Hijack the deal—straight ahead and hijack it!!

Seeing others get SSRs is even more enviable and frustrating than getting one yourself!

Although in this world, up to this point in time, Ayaka Sajō has not yet had the idea of ​​participating in the Holy Grail War.

But the moment it had the thought of joining the war, weren't Command Seals something that could just appear whenever it wanted?!

However—just as Ayaka Sajou used some tricks to try and replace the summoning portal with her own, summoning Yoru to her side of the Holy Grail War world.

Suddenly—Aika sensed countless versions of herself in parallel worlds, all of them moving strangely!

That was a riot that even the Root Princess's love song could not suppress.

"Get out of the way—! You...!" For the first time ever, Aika's perfectly cute face showed an adorable expression of anger turning red.

Her face was flushed red with anger.

So many 'me's'—no, so many seductive and shameless maids—are actually planning to steal my man?

What a joke! How could I possibly give him to you?!

Go to hell! 'Me'!

Before Aika experienced the emergence of her personality, joy, infatuation, excitement, and a deeper understanding of the beautiful human emotions, she unexpectedly encountered the negative emotion of 'wanting to kill'.

At this moment, she desperately wished that all her parallel universe counterparts would die suddenly.

How can there be so many annoying people like 'Sajyou Aika'?

Get lost! You idiot!
