Simulate the universe, starting with speedrunning Greek.

Wait, where are Achilles and Atalanta? Where are those huge cavalry and archers?

After failing to get any answers from his inquiries and suddenly sensing the oppressive aura of the enemy, Spartacus disregarded everything else and, with a healthy smile on his face, began to run wildly towards the enemy's formation without following orders!

Regardless of whether it's the red or black side, both sides' Masters are currently having some existential doubts.

at the same time--

(Achilles: Wait, my good brother isn't coming? I'm outta here! Tamanu, a member of the Moon's Kin: Lord Griffith isn't coming? Then I'm leaving too.)

When he arrived in this world before nightfall, he caused not only an anomaly at the Root, but also changes in the Hall of Heroes. These astonishing changes awoke many of the Heroes in the Hall of Heroes from their slumber, and they sensed his presence.

This also led many heroic spirits who had a connection with the night to notice the changes in the world the night had traveled to.

After discovering that Yoru had no intention of participating in the Subspecies Holy Grail War, not only Achilles but also Tamamo, who had long been acquainted with Yoru and believed that it was important to protect the goddess's beloved, both chose to give up the Subspecies Holy Grail War.

Even many proud heroes who originally had no intention of participating in the war became restless.

(It's that person—!! That person has appeared...)

Damn it, don't stop me! Which world has he descended to? I want to go see the Holy Grail War over there too!

The Greeks and Norsemen reacted most strongly, while many people from other pantheons were also interested in the concept of 'the final trial for mankind'.

Suddenly, the world where night had fallen became a tempting target for countless heroic spirits.

If the pass to that world, the ticket to entry, could be obtained through fighting, then by now, even brains would have been beaten to a pulp in Valhalla!

Even the immense change brought about by the arrival of Night into this world caused many powerful beings, not to mention the Heroic Spirits, including gods who would normally never descend, to become restless the moment they sensed Night's presence.

Especially the Greek gods...!

While these people were still fighting tooth and nail for entry, Ayaka Sajou, who had already grasped the dawn of victory and started with a winning hand, was left with only a single 3 at the end, was now plunged into indescribable despair and gloom.

Even as his younger sister, Ayaka Sajou, grew her own fingers into a swollen, lifeless mass, her eyes remained dull and lifeless.

Because of a moment of carelessness, the first time of the prince she had longed for, loved, and desired, the demon king, was taken away by another woman!

What should have been a 'romantic relationship' (master-servant relationship) with her ended up benefiting a little girl the same age as Ayaka because of the attacks from the 'me' in other worlds.

How could this be?

She was the one who arrived first... whether she was the first to discover His Majesty, the first to extend the invitation, or even nervously and expectantly planning countless wonderful fantasies about her first time with Ye—!!

The more she thought about it, the more agitated and heartbroken Sajou Aika became. Suddenly, she couldn't help but let out a mournful whimper, like a small animal.

Chapter Eleven: Ayaka, Don't Talk! Aika, who's showing signs of evolving into a silly older sister...

The true heroine has indeed appeared, but it's not her, Aika Sajou!

Instead, it was the name of a young girl who was completely unfamiliar to her before and whom this princess of origin would never have cared about.

Linglong Pavilion's beautiful night—! The nemesis that stole our wonderful first encounter! A mitten insect! A thief!

To an unsuspecting person, the pitiful, abandoned puppy-like appearance of Aika Sajou, who looked like a widow, might even lead them to suspect that her boyfriend's virginity had been taken.

But for Sajō Aika, who looks forward to and values ​​every first time, this is a carefully prepared, dreamlike romantic comedy that was never perfect from the start!

But this isn't that person's fault, nor could it be—! That's right, it's not His Highness's fault, it's all those hateful, seductive, and vile maids—!

—Having already lost completely in the very beginning of establishing the contract, the Sajō Aika fell into a deathly silence.

Her lifeless and silent appearance startled Ayaka Sajou, who had always admired her older sister Aika Sajou. She couldn't understand what was wrong with her perfect and all-around Aika.

Is there anything in this world that could cause such a huge blow to the perfect Aika?

"Aigo... Sister..."

"Ayaka, don't speak—!" At this moment, Aika looked at her younger sister, who was almost the same size and age as Reiryukan Misaya, and seemed to be greatly stimulated. Her tone became extremely harsh!

Fortunately, Ayaka Sajou still retained her rationality during this period and was not yet a crazy woman who would kill her sister to prove her sanity.

It's not so much that we say "almost," but rather that we confirm that Ayaka Sajou in all universes possesses the power to link to the Root—omniscience and omnipotence.

However, aside from the timeline of the original Sword, where Sajō Aika turned into evil in order to help the original Sword fulfill his impossible wish that required overturning human reason, in all other timelines Aika—in the timelines where she did not encounter the Knight King, she grew up normally to her twenties and became a useless young woman who was still quite close to her younger sister. She figured out what she really wanted to do and normally hoped to meet her ideal prince (a lovesick girl). From then on, the imperfect Aika was even occasionally called 'idiot older sister' by her younger sister.

From this perspective, Old Sword is truly wicked. Before her personality was stable and she had developed a sufficient sense of good and evil, the actions of the Root Princess were not about good or evil; they all stemmed from the same cause: to fulfill Old Sword's wish—to save Britain and restore the lost Britain to this land.

Of course—this desire to at least create a singularity, or even a Lostbelt worldline, naturally led Aika to think of borrowing the power of the beasts.

Unfortunately, the person she loved did not love her. For the sake of the world, Old Sword could betray his own wishes and Master Aika without hesitation, and for Aika's sister, Sajou Ayaka, Old Sword could betray everything else without hesitation.

Approximately equal to—Ayaka is greater than the world is greater than Aika!

To tell you a joke—it even led to Old Sword pretending to be deaf and dumb, ignoring the series of evil deeds Aika did before helping him fulfill his wish, until he made up his mind to betray Aika. The most important reason for this major turning point was that Aika finally pushed Ayaka into the big hole, intending to feed her to the 666 Beast, right?

Old Sword: Feeding Tokyoites 666 to save Britain? — Sure! Feeding Sajō Ayaka 666? — No way!!

Although Ayaka's character design has always been jokingly referred to as a Mary Sue heroine—with many settings like being arrogant and domineering—in reality, Ayaka can only seduce young Karami. On the contrary, Ayaka is pursued by almost all male Servants, such as Old Saber and Dog Brother.

What's more, the old sword, who was like a cold and aloof god in front of Aika, turned into a pervert in front of Ayaka, who wanted to smash the bathroom with the holy sword Excalibur and openly peep at girls taking a bath.

Fortunately, Aige's attention is no longer on Old Sword in this world, and who Old Sword likes is none of her business.

Isn't it normal for people to have completely different feelings about different people?

Taking a deep breath—! As Sajou Aika gradually calmed down, she didn't take her anger out on her sister, and even began to reflect on whether she had been too harsh just now.

After all, unlike King Arthur, whose moral values ​​were originally quite flexible and ambiguous, the person that Ai-ge is now focusing on is a man who is known as an absolute evil in human history.

Because she wanted to understand this man deeply, Aika also studied everything he did in depth.

It is not simply evil—the deepest essence of absolute evil and human evil is human love!

Because they love everything, they are willing to bear all evil until the hero defeats them.

So—the person she admires is a Demon King who is more loving than anyone else!

Having deeply realized this, and even that the humans of the Norse world were created by her, then Aigo—shouldn't she love humanity even more!

Although she doesn't think she can do that right now, that she can't deeply love every human being, since she's completely uninterested in other people, as long as that person still loves humans, then she's willing to love them, even if that behavior is just a simulation.

"Sister... Sister?" Ayaka Sajou, who had been intimidated by Aika's terrifying expression just now, looked timid and on the verge of tears. She didn't know what she had done wrong. Was her bandaging technique too clumsy?

Although she was delighted that even her clumsy self could help Aika-neechan, and it seemed nice that her perfectionist sister was occasionally a little clumsy, it was a pity that she wasn't as perfect as her sister, who could do everything perfectly. Even the simplest bandaging was done terribly—Ugh! Looking at the huge mess she had made of bandaging Aika-neechan, Ayaka Sajou lowered her head in shame, feeling utterly embarrassed.

“It’s okay, Ayaka…” Aika said in an incredibly gentle tone.

"I'll handle the rest myself. You go and rest. Dinner will be ready soon." Aika patted Ayaka's head. That's probably how it should be done, Aika thought subconsciously.

Am I passing on my gentleness to my younger sister?

It's not a pretense or an act; Ai Ge is genuinely and clumsily trying to love others.

Of course, she was very smart and knew that there were differences between close and distant relatives. Even the king who loved everything would show more favoritism to those around him.

Therefore, one can undoubtedly be closer to one's younger sister, who is related to one's blood.

As for his adoptive father—Hiroki Sajou?

Uh……

She briefly compared the current Ayaka, who looked flattered and adorable like a trembling little rabbit, to the old man who usually avoided her like the plague and was genuinely terrified of her.

Thinking that getting close to that kind of person would probably be ten times more difficult than becoming friends with a random stranger on the street, Aige decisively chose to give up!

Chapter Twelve: To please that person, we must summon the strongest hero—the "Grand Hero"!

Getting intimate with an old man is disgusting...!

In Aika's eyes, who has never established a normal father-daughter relationship, Hiroki Sajou is no different from any other lewd old man walking around on the street.

Because the arrival of night caused the omniscience and omnipotence to fail, everything became chaotic. Even if the root was reconnected, the future development of Sajou Aika could not be seen. At this moment, the whole world in front of her finally became a little more interesting.

Even though none of these things are as interesting as the source of all this, His Majesty the Demon King himself, he still brought some joy to Aika's blank-slate heart.

Following our instincts, we develop preferences; we are more willing to get closer to cute things and more inclined to stay away from ugly things.

At this moment, Aika Sajou seemed to be able to understand the pursuit and preferences of beauty and ugliness as a "human being".

Aika's most basic definition of beauty and ugliness is that the most beautiful existence is one whose posture is like the night. After all, this is also described in mythology, and even the gods are deeply infatuated with his bewitching appearance.

So, aside from the night, especially in terms of appearance, it must be ugly!

And without a doubt—Sajō Ayaka, who hasn't grown up yet and whose beauty hasn't been sealed by glasses, has a face that would make even the aloof male god (pervert) that Aika can't get his hands on blush.

As a gift of charm that stands in contrast to the 'beautiful boy', Ayaka Sajou, who has not yet grown into an unparalleled beauty, was incredibly cute as a child. Otherwise, in the original storyline, Aika, who had not yet turned evil, would not have been so close to Ayaka besides Old Sword, and would not have even praised her cuteness in her heart.

Little Ayaka, overwhelmed and flustered by her sister's unprecedented gentleness, was at a loss for how to respond...

Faced with Ayaka's reaction, it seemed that her reaction did not match her knowledge.

Aika: '—!? Did I do something wrong?'

Ai Ge got a headache and decided to put aside the matter of building a good sisterly relationship with her younger sister for now.

Back to the main point—the Heroic Spirits still need to be summoned. Even though I missed out on my Prince and Demon King! Ah, ah, ah, as expected—just thinking about it still makes my throat hurt with anger, that little black-haired, red-eyed loli has already set her sights on her, damn it—! I must snatch my Prince back later.

But before that, we can only summon another Heroic Spirit as a backup.

Based on Aika's understanding of Yoru, if she were to use force, it would definitely backfire and force her to the opposite side! But since she couldn't directly establish a master-servant relationship, she needed to establish an alliance first to have a better reason to get closer to him.

That's right! After she could no longer establish a contract with the night, the so-called master-servant contract was no longer so sacred in Ayaka Sajou's eyes. It became a dispensable and trashy existence that she despised. After all, seeing the mark on her chest reminded her of the fact that she was a loser, and she didn't even dare to recall what she was thinking when she first set the Command Seals in such a position.

As expected—! That 'woman' (loli) named Reiryukan Misaya deserves to die!

As the light faded from Ayaka Sajou's eyes, dark energy began to emerge from behind her. Startled and unaware of what had happened, Ayaka Sajou hurriedly left the kitchen, leaving Ayaka to handle the situation.

So what kind of Heroic Spirit should we summon?

Considering Ye's identity, Aigo finally had an idea.

“You must be longing for a hero who can defeat you. For you, who are absolute evil, there is nothing more painful than being eternally invincible…” Aika murmured, suddenly her small hand caressing her soft, slightly curved little mound, where her heart beats.

I can now somewhat understand that feeling called 'heartache'.

What Absolute Evil craves is to be defeated, for humanity to transcend itself, to overcome humanity's ultimate trial, and to move towards a more distant future.

Therefore, Aika is determined to fulfill that person's wish, to ensure that person's life is preserved while also allowing them to experience the joy of being successfully defeated!

"I need—the strongest hero—!" Ayaka murmured, a strange light flashing in her eyes.

The strongest Heroic Spirit, the strongest Hero—that's right, it can only be the Grand Rank.

And among the seven classes, the strongest Grand Knight is undoubtedly the Saber class. The strongest Saber class is best suited for a female. Aika finds it difficult to accept having a man as her contract partner, even though she can no longer form a contract with Yoru, and even though that contract no longer holds any special meaning. Contracting with another male would still make her feel uncomfortable.

Therefore, the target will be female Servants who possess the qualifications of Grand Sword or candidate!

She will lead the swordsman to eliminate all obstacles for that person, and finally present the challenge book with a perfect answer!
