Chapter 269 The Princess of the Roots, Aika Sajō
Sajō Aika is an extremely unique existence in the Type-Moon universe.

Her uniqueness lies in the fact that she was connected to the Root at birth, thus possessing overwhelming magical power and talent, and having power equal to or even greater than that of a magician.

She is therefore known as the 'Princess of the Roots'.

Because of this uniqueness, Aika Sajou possesses near-omniscient and omnipotent power in the Type-Moon universe.

This made her completely uninterested in the vast majority of things in the world.

But with the arrival of Fu Le and Hei Ta, things that were not within her foresight suddenly appeared in the Type-Moon world.

And this is precisely what Ayaka Sajou has been striving for: the sense of the unknown.

However, because she didn't want her life to be too dull, Ayaka Sajou chose not to predict her future.

This is why she didn't discover Fu Le's whereabouts when Fu Le first arrived in this world.

She only became aware of Fu Le's presence after Fu Le entered the Vortex of Origin.

The feeling of complete ignorance fascinated her, and she immediately wanted to find Fu Le.

However, there is no information about Fu Le in the Type-Moon world, and Fu Le has consciously erased his traces in this world, which makes it difficult for Aika Sajou to find any trace of Fu Le.

After all, Fu Le knew that there were many dangerous people in the Type-Moon universe.

He took thorough precautions in expelling the poison of corrupted knowledge.

He took precautions both physically and mystoriously.

This is why Aika Sajou couldn't find him for so long, since Fu Le used technology from another world, not the Type-Moon world.

Sajō Ayaka, completely unaware of these techniques, easily fell victim to them.

But Ayaka Sajou also has a very strong will.

Having finally encountered something unknown to her, how could she possibly let go?

Since we can't find the other person through magic, let's use physical methods.

Thus, after the Fourth Holy Grail War, Ayaka Sajō embarked on a world tour, relentlessly searching for unknown traces.

Until recently, she came to Fuyuki City.

The moment she set foot in Fuyuki City, the intelligence concealment centered on Fuyuki City lost its effectiveness.

Fu Le arranged all of this in an attempt to minimize the impact of the Fourth Holy Grail War on Fuyuki City, since Gilgamesh's actions during the Fourth Holy Grail War were far too outrageous.

Sajō Ayaka was also affected by this.

Otherwise, if she had just seen the news of a suspected missile attack on Fuyuki City, she would have been able to guess that Fu Le was in Fuyuki City.

However, these two consecutive moves completely blocked Sajou Aika's attacks.

So much so that she searched for Fu Le all over the world for ten years.

When she arrived in Fuyuki City, all the hidden information about Fuyuki City came into the possession of Ayaka Sajou.

The next moment she understood everything; the unknown person was in this city.

In order to meet the unknown in a friendly manner, Ayaka Sajou decides not to use overly dangerous methods.

After discovering that the Holy Grail system was locked, but not controlled by anyone she knew, she set her sights on the Holy Grail system.

Thus, under her guidance, the Fifth Holy Grail War, which should never have happened, occurred.

She did this simply to lure out that unknown person.

"Oh, the Holy Grail System has been activated. The Fifth Holy Grail War is about to begin?"

Shortly after the Command Seal marks appeared on the back of Sakura's hand, Sakura told Fu Le about it when she came to deliver food to Fu Le's room.

"No wonder the three of you came to deliver dinner together tonight!"

Looking at Sakura and Medea and Artoria who came in with her, Fu Le first teased the three people in front of her.

Fu Le and the other four are very busy people, so Xiao Ying usually brings them meals.

When he saw the three of them appear together today, he knew something must have happened.

However, he did not expect that the Fifth Holy Grail War was about to begin.

During this period, Fu Le was immersed in his research, which meant he didn't devote much attention to Fuyuki City.

Now, reminded by Sakura, he immediately expanded his mental power.

Then he saw an unexpected figure.

"It's actually her?"

Fu Le was stunned for a moment.

Fu Le knew a little about Sajou Aika.

After all, both the old Saber and the old Gilgamesh are very cool, especially their Noble Phantasms, which are particularly eye-catching.

Therefore, Fu Le had learned a little about the two characters from "Fate/Prototype: Fragments of Blue Silver" who appeared, so he had some knowledge of Ayaka Sajou.

But this isn't the set of Fate/Prototype, is it?

So how did she end up here?

Fu Le couldn't figure it out for a moment.

Meanwhile, as Fu Le used his mental power to investigate the situation in Fuyuki City, Sajou Aika, who was located somewhere in Fuyuki City, suddenly smiled.

"Got you!"

When Fu Le saw Sajou Aika, Sajou Aika also saw Fu Le.

Although in terms of pure strength, Fu Le is far superior to Sajo Aika.

However, Aika Sajou is essentially playing on home turf in the Type-Moon universe.

In the Type-Moon universe, Aika Sajō is considered omniscient and omnipotent.

Thus, Sajou Aika found Fule's trail.

"The Matou family?"

Having determined Fu Le's destination, Sajou Aika excitedly headed towards the Matou residence.

"Tsk, have you been discovered?"

Sensing that Ayaka Sajou was rapidly approaching, Fu Le said to Sakura, Medea, and Artoria beside him, "We have an important guest coming to visit. You should make some preparations."

Although she had some doubts just now, Fu Le had already guessed the other party's purpose.

If the other party is truly targeting something unknown to us, then she might not be an enemy.

Moreover, she might be the kind of top genius worth recruiting.

As the princess who connects to the source, taking the star goddess as an example, Ayaka Sajou can be considered a born messenger.

Just like the direct descendants of star gods who can reproduce, such as the progenitor star gods and immortal star gods.

For example, the insect king.

In short, Aika Sajou is very talented, but the stage of the Type-Moon world is too small.

If she were on a world stage like Xingtie, she would surely shine.

While arranging for Sakura and the others to make preparations, Fu Le also walked to the gate of the Matou residence to greet the princess.

After all, the other party was the host, and he, as a guest from another world, was the one who had come to visit, so of course he had to personally greet the other party!

Sajo Aika moved quickly; she appeared in front of Fu Le as soon as Fu Le arrived at the gate.

"That's right, it's you. The aura I sensed in the source was you."

Upon seeing Fu Le, Sajo Aika was the first to speak.

"That's right, that's me."

Fu Le responded with a light laugh.

Since Aika Sajou had said that, Fu Le knew exactly when she had caught the other person's attention.

Since that's the case, there's no point in trying to fool anyone.

He admitted it directly.

Upon hearing Fu Le's admission, Sajo Aika immediately opened her arms and hugged Fu Le, then wrapped her arms around Fu Le's neck and pressed her face tightly against Fu Le's chest.

"I've finally found you, my prince!"

Said Sajo Aika.

Behind Fu Le, Sakura, who had come out with him to greet Sajou Aika, caught the attention of Medea and Artoria, who both paused for a moment. Then, the three of them displayed different expressions.

Regardless of their expressions, they were all very unhappy with Ayaka Sajou's actions.

They couldn't wait to rush up and tear Sajou Aika apart.

But considering that the other party was the distinguished guest Fu Le had mentioned, the three of them ultimately held back.

"You shouldn't call me Prince."

After pushing Sajou Aika away, Fu Le said to her helplessly.

Fu Le only felt awkward around princes and the like.

Although he himself is a bit of a chuunibyou (a person with delusions of grandeur), there are some words that even a chuunibyou teenager would feel ashamed to hear.

For example, 'Your Highness' or something like that.

"Hmm, doesn't 'Prince' sound good? How about 'Darling'?"

After Fu Le pushed her away, Sajo Aika turned around and came to Fu Le's side, putting her arm around his and continuing to talk.

Her face was still full of smiles.

It seemed as if seeing Fu Le brought her immense joy.

Fu Le tried to reach out and push her away again, but she clung to him like glue. If Fu Le used any more force, she would probably get hurt.

Thinking of this, Fu Le still didn't push Sajou Aika away.

He looked down at Ayaka Sajou helplessly and said, "Forget it, let's go back inside and talk about it."

"it is good!"

Seeing that Fu Le finally stopped pushing her away, Sajo Aika replied happily.

The three bystanders were even more upset.

After returning to the house, Sajou Aika sat down next to Fukuro again.

"Let me introduce myself first. My name is Fu Le, and I come from Luofu Immortal Ship."

"My name is Aika Sajou."

Upon hearing this, Aika Sajou immediately replied.

"Sajō Aika? I think I've noticed something special about you, so what brings you here?"

Although Fu Le had a general idea of ​​what Aika Sajou was thinking, she didn't know much about Aika Sajou, so she needed to explain the real situation herself.

"I've come to seek refuge with you, my dear!"

"Sajyou Aika said with a playful expression."

"Take refuge in me?"

"That's right, I know you have the ability to leave this world, and I want to leave this world with you and explore the unknown!"

Sajou Aika's eyes were full of anticipation.

In the Type-Moon universe, Ayaka Sajou is a god-like being who is almost omniscient and omnipotent.

However, she lacked a platform to showcase her abilities.

This made her very lonely.

She and loneliness.

That's why she's so drawn to unknown individuals.

In some timelines, Aika Sajou would ultimately choose suicide to find relief from this boundless loneliness.

For her, going to another world was not dangerous at all; at worst, she would just die.

Death is the only way through the ages.

If you're not even afraid of death, then what else is there to be afraid of?
Sajō Aika has this kind of mentality.

Therefore, going to another world posed no danger to her whatsoever; on the contrary, it was full of benefits.

It can be said to be entirely beneficial without any harm.

"I see, I understand what you're thinking."

“You are indeed a talented person and qualified to work with us, but we have only known each other for a short time, so we will have to wait a little longer.”

"For example, I need to discuss this with my companion. Before that, I don't know if Ms. Sajo has a residence in Fuyuki City?"

Fu Le thought for a moment and then said this to Sajou Aika.

Although Aika Sajou is very talented and capable, Fu Le still has some reservations about her.

Because of Aika Sajou's unique living environment, her values ​​are completely different from those of ordinary people, and she is also very 'willful'.

Although Fu Le is surrounded by many dangerous people.

Both Rakshasa and Mirror Stream are dangerous figures, and even Black Tower and Ruan Mei are considered dangerous by many.

But they were all very rational.

After all, in the world of Starry Sky Railway, there are even stronger beings above the strong.

No one is invincible.

Therefore, a humble heart is essential for every truly strong person.

But Aika Sajou is different. Born into the Type-Moon world, she is invincible, and her mentality is completely different from that of Fu Le and others.

Furthermore, her lack of fear of death made Fu Le very worried that one day she would give Fu Le a big performance.

Just like her performance in Fate/Prototype.

The old sword, also known as the male version of King Arthur, has the same wish: to save Britain. After learning of his wish, Ayaka Sajou decides to fulfill it for him.

Sajō Aika also knew that the Holy Grail alone could not fulfill the Old Sword's wish to save Britain.

But she has a way.

So what was his solution?

Awaken the 'beast' to destroy the quantum record fixation tape, undermine the foundations of human reason, and recreate Britain.

She sacrificed many people for this, even planning to offer her own younger sister as a sacrifice.

And once her plan is realized, countless people will die silently.

She only found out at the very end that the old sword in Sajou Aika's plan had betrayed her.

After all, King Arthur simply couldn't bring himself to kill all of humanity to save Britain!
This is Ayaka Sajou's record.

She was indeed a very good assistant, but she was very willful.

Even though she knew Old Sword would never accept her actions, she still did them despite having the ability to fulfill Old Sword's wish.

Even if it means keeping it from the other person, you have to do it.

Therefore, Fu Le has absolutely no confidence in Sajou Aika.

The more capable such a person is, the greater the harm they can cause.

"I have nowhere to stay! And please don't call me 'Miss Satori,' just call me 'Aika.'"

Upon hearing this, Aika Sajou quickly replied.

Then she looked at Fu Le expectantly, waiting for his answer.

"Then you can stay here, Medea. You and Sakura help Sajō and Aika prepare a room."

Under the intense gaze of Ayaka Sajou, Fu Le changed his words.

"Ok, I see."

Medea nodded slightly, then looked at Sajō Aika and said, "Please come with me, I'll show you the way, Miss Sajō."

"Ok."

Under Fu Le's gaze, Sajou Aika reluctantly released her arm and followed Medea toward the guest room.

"Sajō Aika? What a troublesome person!"

After Medea left with Sajou Aika, Fu Le lay on the sofa and thought to himself.
