"You can refuse me, but I will still help you. In Jiangnan, this is called being a 'simp'."

As he spoke, Shirou looked at Saber very seriously and said earnestly.

"So, Saber, I want—"

Saber froze, as if she had realized something, and blushed instantly, even subconsciously taking a step back.

"shut up!"

Even so, Saber ultimately couldn't resist Shirou's sweet talk. The past week of spending time together had deepened their bond, and she still couldn't escape Shirou's clutches.

After that, Shirou and Saber's relationship reached a new level. Although they still lived the same way every day, there were more things to do at night.

Scáthach also came to spar with Shirou during this period, but she was always easily defeated by him.

"Just you wait, I'll definitely defeat you next time!" Scáthach covered her tattered bodysuit with her hand and threatened Shirou.

"Then I'll be waiting for you."

Scáthach, trembling with anger at Shirou's words, quickly left.

Besides Scáthach, Nero also challenged Shirou to a duel, despite already knowing Shirou's strength. Nero's attitude remained arrogant.

"Hmph! I only need to make a slight move~"

A moment later, Shirou pinned him to the ground and rubbed him against the ground. He could not resist no matter how much Shirou squeezed and rolled him, and could only whimper and beg for mercy.

"Waaaah! I'm not going to fight anymore!!"

……

One morning, Shirou woke up and instinctively reached out to touch the soft body in his arms, only to find that it was empty.

"Ok?"

Her pale golden eyes opened, and she looked around with a hint of confusion.

"Where did it go...?"

Shirou got up and went to the living room.

Because it was still early, Sakura and Illya hadn't gotten up yet, so the house was quite quiet.

Upon arriving in the living room, Saber was still nowhere to be seen.

However, they then heard the doorbell ring immediately afterward.

Shirou opened the door, only to find two girls who shouldn't be in this era.

"Um, hello senpai, my name is Fujimaru Ritsuka!"

“Uh… Hello, I am Mash Kyrielight…”

A girl with orange-red hair was looking up at Shirou with great enthusiasm, while the girl with short cherry-colored hair next to her looked a little reserved, with her hands folded in front of her lower abdomen.

"you……"

The moment Shirou saw the two girls, he roughly understood what had happened.

Then, the girl named Fujimaru Ritsuka grabbed Shirou's right hand, raised it to her chest, and said earnestly.

"Senior, please come with us to the Singularity. This is my lifelong request!"

"Senior, you've already said this to so many people..."

Mashu, who was standing next to her, muttered something under her breath.

"Are you two from the future?" Shirou asked at this moment.

"Hmm, as expected of a senior, you're not surprised at all by our background. The doctor was right after all."

Fujimaru Ritsuka said with a hint of admiration.

Shirou sighed helplessly.

"Honestly, I was planning to take a month-long vacation."

It seems the only option now is to take a vacation at the singularity.

Moreover, Shirou already had a premonition that the place he was going to next was related to Saber, who had suddenly disappeared.

"There's really no other way, let's go."

……

"Testing in progress—"

"Judgment - Attribute: Chaos - Good"

Buzz————

As a synthesized electronic voice sounded from the detection gate, Shirou followed Gudako and Mashu into the interior of the institution, which stood amidst the snow.

This is Phineas Chaldea, the future institution for ensuring the survival of humanity.

The Magic Workshop was built in a location that would not be interfered with by any country and could keep its secrets.

Chaldea is not an observatory for looking up at the stars in the universe from Earth, but an observatory built to look down on everything on Earth from the void.

The organization's mission is to ensure the long and resilient continuation of human history.

Thus, this research institute and observation center, which transcends the distinction between magic and science, and brings together researchers from various fields, was built in order to observe this world, which cannot be fully understood by relying solely on magic, nor can its entirety be measured solely by relying solely on science.

This is an organization jointly established by various countries to prevent the extinction of humanity.

Arriving at a tightly closed door, Fujimaru Ritsuka stepped forward to verify her identity before the door opened to both sides.

Let's go in.

,senior!"

"Ah."

Shirou followed him into the central control room.

The next second, a vast space resembling a war room, with its surroundings entirely in a deep blue hue and filled with a futuristic feel, appeared before Shirou's eyes.

In the very center of the central control room was a huge globe, entirely blue and shimmering with light, suspended in mid-air.

"Yo ho~ Welcome to Chaldea, Orihara Shirou."

Chapter 1 Chaldea and the Sixth Singularity

The speaker was a tall woman with a beautiful face and an intellectual air, Leonardo da Vinci.

Beside him, Romani Archman, dressed in a white coat, smiled at Shirou: "Welcome. I think you've already guessed why we invited you here."

Upon hearing this, Shirou nodded knowingly.

He was extremely clear about Chaldea, the people living there, and the information about the Lostbelts.

Arriving at a tightly closed door, Gudako stepped forward to verify her identity, and the door opened to both sides.

"Let's go in, senior!"

"Ah."

Shirou followed him into the central control room.

The next second, a vast space resembling a war room, with its surroundings entirely in a deep blue hue and filled with a futuristic feel, appeared before Shirou's eyes.

In the very center of the central control room was a huge globe, entirely blue and shimmering with light, suspended in mid-air.

“So, the next place we’re going to is…” Shirou looked at Roman.

"Yes, we've already experienced several singularities. The next one is the sixth, set in the 13th century, in Jerusalem, which is widely known as the 'Holy Land.' To be precise, it's around 1273 AD, the year the Ninth Crusade ended and the Kingdom of Jerusalem disappeared from the face of the earth..."

Roman's main purpose was to explain things to Gudako and Mashu.

"The Sixth Singularity is gradually deviating from the course of human reason. So far, all that has been done at the destination of the 'Spiritual Transfer' has been to fight the Holy Grail of Solomon that is disrupting 'that era.' But this singularity itself is gradually becoming a 'non-existent' history. If left unattended, even if we can reset the human reason of Solomon through incineration, humanity will suffer enormous damage. Therefore, the foundational evaluation of the human reason of the Sixth Singularity is classified as EX-rank, meaning that everything is a special case. The support that can be provided from Chaldea this time is also very limited, and it is completely unclear what will happen..."

Roman sighed softly as he spoke.

However, after confirming the information, Gudako felt no worry at all, and even became impatient.

"Alright, alright, let's go!"

"Hey, you two..."

Roman had barely raised his hand when Gudako had already dragged Mashu away and disappeared.

Fufu also chased after them.

In the end, Roman could only look helplessly at Shirou.

"Thank you for your help. Please keep an eye on them for a while," Roman said sincerely. "We'll do our best to help if they need anything once they get there."

"I'll go too."

Leonardo da Vinci then spoke.

"Hey? You're going too?"

Roman paused for a moment upon hearing this, looking at Leonardo da Vinci with surprise.

"Hmph~ I'm also a little interested in the design of Jerusalem~"

A smile of interest appeared on Leonardo da Vinci's face.

"Simply having a simple artistic interest is actually very important to humankind!"

"Are you sure? Once the spirit particles are transferred to the singularity, they can't return to Chaldea until the foundation of humanity is restored. If something goes wrong, it will be too late. What will happen to Chaldea if something happens to you?" Roman said with some concern.

"Hey, even if I'm a particularly narcissistic person, I'll still get a little angry when I hear something like that, you know?"

Da Vinci, hands on his hips, said somewhat displeasedly to Roman, "What Chaldea needs most right now is humanity, Romani. I'm just a carefree servant."

"Alright, alright, since you've put it that way, I can't stop you now."

Roman said helplessly.

Then, Leonardo da Vinci looked at Shirou with some anticipation.

“Let’s go. Even if the difficulty is EX, it’s still basically 13th-century Jerusalem, a place where many people rely on their faith. The battleground should be in the city, right?”

Da Vinci said confidently, "In that case, I should be able to use my full strength, since there won't be long-distance travel like in North America in the city!"
