Xingyue, is Xiaokai also considered Kai?

“Listen, Tiamat’s mother, don’t let my appearance fool you, I’m actually quite happy. Someone actually said she’s my mother, and even has the same blue hair as me. How could anyone not be touched? But you always misunderstand me… Really, it really hurts me…”

"Waaaaah, no, I hate Mother..."

It was obvious that Tiamat was struggling to cope. If Novia hadn't been there, she might have burst into tears. So when Novia felt Tiamat's trembling body, she glanced at Lushena.

Where do you feel pain?

"Wow, you're not really my teacher, yet you're talking to me like that... But that's another matter. Right now, I'm feeling really upset."

Upon hearing this, Lushena raised his head and smiled. "But I can't show it on my face. However, Mother Tiamat, I am no longer upset. I know I was wrong. You are the creator goddess of Mesopotamia. Ever since I met you, I have known that you are a wonderful mother."

"My mother was slightly moved. She said, 'That's how it is with Vairocana... He's a good child, definitely. Hehehe, he's been respected.'"

Tiamat, aren't you being a little too naive?

Erito suspects that Tiamat was tricked into becoming a Servant by Novia. How can the Mesopotamian creator goddess be so naive? She seems like she would agree to do strange things if asked.

Regardless, Eri shook her head helplessly as she followed behind.

I should have known better than to come. I should have left with Chitose instead, so I wouldn't have to endure this inexplicable display of affection here.

Erise sighed subconsciously and continued walking into the shop. At a table diagonally opposite the group, a very conspicuous female Servant was silently standing there. Since she was the only Servant there before Novia and the others arrived, Erise slightly shifted her body from the chair to look at her.

The person's skin was as pale as porcelain, lacking vitality. She had long, wavy hair and, although taller than Circe, was still rather petite. While her hair was embroidered with geometric patterns, unfortunately, Eri's knowledge was insufficient to pinpoint the exact cultural origin of these patterns.

"Egypt."

Oh dear, this is terrible.

Before Eri could answer Novia's pointed question, she realized that the Servant was also staring straight at her.

Beneath this servant's cloak are a pair of sharp yellow eyes with deep dark circles.

Eri initially guessed that it might be because of her curious gaze that made her uncomfortable, or perhaps she already knew about the bad reputation she had as a Grim Reaper. However, it seemed that neither of these was the case. The Servant's gaze was not directed at her, but at Ruchena, who was standing next to her with his hands supporting his chin and his eyes shining as he looked at Novia.

Then, a woman with dark circles under her eyes stood by the table and stared at Vairocana as if she were carefully examining a specimen in a museum.

"A strange person is coming..."

Eri said in a suspicious tone.

"You... if my calculations are correct... you are the one who suddenly appeared thirty days ago, the one with unparalleled mystery... am I right?"

Her voice was cold, yet it subtly carried intense emotion.

"Yes, that's right—I am Vairocana Buddha, but I am currently in a state of having lost my Buddha-nature and Buddhahood."

Lu Sheye was not intimidated at all and answered her directly.

"...Buddha? Can Buddha become a Servant? In any case, then you are essentially the last Servant—whether you chose it or not."

"The last one? You mean Lu She is the last Servant? But that was the day Mother appeared a month ago too."

Tiamat said with a puzzled tone, "Right? We came that day too, Novia."

"...Hmm? Two? How is that possible? The calculations can't be wrong. There can't be two; there can only be one... And... who is Mother? Ah..."

At this moment, the woman with dark circles under her eyes seemed to realize how sudden her actions had been.

Not only did Lushena stare at her in disbelief, but she also seemed to notice the speechless Novia and Tiamat, and Eri.

She suddenly covered her flushed cheeks, pulled down her hood, and shrank back—

Her name was Euclid.

Chapter 519 The New Emperor.

Euclid was a famous mathematician and astronomer in the ancient Greek cultural sphere.

Speaking of the English pronunciation of "Euclid," it has practically become synonymous with geometry. As wise men who laid the foundation for knowledge in the ancient world, philosophers have "Plato," scientists have "Archimedes," and mathematicians will bring up the name "Euclid." I believe no one would disagree with this.

Unrelated to military matters, followers of pure mathematicians are already extremely rare, and more importantly—

As far as Eri knows, there is only one Descendant in the entire Mosaic community right now: the Demon King, whose whereabouts are unknown. Euclid in front of her is not only a Descendant, but also a woman... The Euclid in historical records should be male, but it seems that she is female now.

Because they caused immense damage to both sides in the previous world war, the few Servants of the Descendant class have always been considered symbols of calamity, and people avoid them like the plague.

Novia then generously invited Euclid to sit down.

He was also puzzled because, under normal circumstances, Euclid in the Fr world should be managing the Library of Alexandria in the city of Tama, not in the underworld of Tokyo.

"...Of course I've heard of the existence of a 'Grim Reaper' who specializes in hunting Servants, but I never expected it to be a young girl like you. Don't worry, I'm completely harmless."

"This one……"

Eri remained wary and cautiously replied, "It depends on what kind of person the Master is."

In Erise's view, the aura emanating from Euclid was different from the fear or cold fighting spirit naturally emanating from Heroic Spirits. That unknown aura gave people goosebumps all over, as if clear rationality and chaotic passion were intertwined and coexisted, giving people a very strange feeling.

What is this oppressive feeling...? Is this... the majesty of a king...?

Of all the Servants Erise has fought in the past, the one whose atmosphere is closest to this one is the one that feels the most right now.

However, Eri also keenly noticed that the strange sense of oppression emanating from Euclid disappeared after he saw Novia.

"...You must be a middle school student. Why aren't you going to school? That's not good."

Being confronted like this, especially by a scholar of this field, made Erise, who already held some respect for her, feel somewhat apprehensive and shrink back. At this moment, Novia spoke up for her in a very honest way—or rather, she revealed Erise's secrets.

"Because Eri, she doesn't like going to school."

"...Wait, Novia, wait a minute..."

Eri felt she didn't hate studying; she just wasn't used to being around kind classmates who treated her like toys. Especially since this guy was so oblivious! She'd told him to stay away, and she'd just clearly refused him, so why was he still clinging to her like this…

At the same time, Euclid, looking at Erise, frowned in surprise, his lips trembling as he said:

"Is that so... like that... not at all Euclid..."

Erise originally thought she would be scolded in this situation, but instead she became listless and dejected, and even timidly used a fork to turn the strawberries.

"Hey~ Is anyone home, Euclid? I'm telling you, Euclid, do you really need to feel guilty about this?"

With an air of detachment, Rousseau cheerfully encouraged Euclid, saying, "It's true that the neglect of education is regrettable, and life's teachers are very important."

“...Your real name is ‘Lushena’, right? Well then, let me introduce myself.”

As Euclid spoke, he took off his hood, revealing his face, which was that of a somewhat mature young woman. She was quite slender, and her eyes, which were not very attractive to begin with, looked as if she was angry 24 hours a day.

“I am Euclid, a Servant of the Descendant class. I currently work as a librarian in a library in Tama. I don’t know if you’ve heard of me, but Alexander is what I’m known as among the common people, and it’s also the name of the largest library in Mosaic City. I help edit textbooks there, or assist in answering inquiries from library visitors.”

"I see, Alexander...the one from Egypt?"

Erise finally asked the question that had been on her mind: "Where did the first Pope Novia go after meeting Claudius?"

Because of Lucius, her martial arts teacher, Eri was quite familiar with the little stories about Novia that he told her over and over again. She remembered that Alexander was, in Lucius's words, the first love of the first pope... it seemed to be unrequited love? Anyway, it didn't work out, and she was also a girl who was like a mathematician.

"Yes, but in my time, Alexandria was ruled by Ptolemy, not by the Roman Empire or Lord Novia..."

The gloomy mathematician sighed, "I know absolutely nothing about this, so if a believer wants to know something from me, I really don't know."

"By the way, Xiao Ou."

Lushena wanted to understand the true meaning behind her seemingly prophetic words, so he leaned forward and asked, "What did you mean by 'last Servant'?"

"Mother, I'm curious too."

Upon hearing this, the gloomy mathematician swallowed the half-eaten strawberry in his mouth and continued:

"...Actually, a few days ago, a medical servant related to obstetrics and gynecology came to see me. He said that recently, there have been a series of cases in Mosaic City where newborns who should have been summoned have not appeared in the world."

As you all know, since the founding of Mosaic City, there has been a certain probability of these symptoms occurring. However, in the past month, the number of cases has surged. Although no major problems have occurred yet, statistically speaking, this situation is very abnormal, especially—

In every case of a lost Servant, there has not been a single report of the Servant's return…

Servant loss, as the name suggests, means that the Master loses their Servant.

However, as long as you are in Mosaic City, you can summon Servants again. Although it is impossible to summon the same Servant as before, you can indeed summon them again. The time it takes to summon them again varies from person to person. Some people can do it the next day, while others have to wait up to a year.

"I see, this is very unusual."

"Hmm, this is very abnormal."

Euclid said, "Given such a large number of people, this is simply impossible. If we take the emergence of new Servants into account, in other words, the current situation is that since a certain point in time, no more Servants have been summoned in Mosaic City. That makes more sense."

"So, Ou, then I'm the last Servant?"

"That was my intuition, but..."

Euclid looked at Ruchena beside him and the two people opposite him. His already lifeless face became even more gloomy as he muttered unfamiliar words to everyone.

"Ugh, how annoying... This isn't Euclid at all... Ia Ia... BulgtomFugtragurn..."

Indeed, the Outer God associated with Euclid, the Descendant, is Hastur, the Lord in Yellow, who is the same person as Hokushin Myōken Bodhisattva in the Mi sect of Buddhism. Mi sect Buddhism is a system that takes the Awakened One, the Dharmakaya Mahavairocana, as the supreme and fundamental Buddha. Therefore, it can be said that Vairocana is the boss of Myōken Bodhisattva.

This may explain why the oppressive aura emanating from Euclid disappeared in the presence of Novia and Rusena.

Thanks to this meeting with Euclid, Novia also gained some insights into the current state of Mosaic City, because R'lyeh is a non-Euclidean geometric city, while Mosaic City is entirely orderly and meticulously planned...

suddenly.

Euclid pointed at Novia, as if talking to himself.

"Here we go again? Hmph, it's nothing, a mathematician's intuition is very important! And my friend, even I can sense that you're different. I can't sense any of the magical power of your class from the cute little Servant next to you, and neither of you belongs to the Holy Grail War's format. Perhaps there's some factor that makes you and Ruchena attracted to each other?"

"That's it! He truly deserves to be called a great mathematician! He has such a discerning eye for recognizing his teacher!"

"I am a mathematician, so please don't be shy and give me a few more compliments!"

Vairocana nodded with obvious admiration, and Euclid beamed with joy at the sight.

Eri felt that what she said made sense. Although Euclid was just a mathematician hero spirit, as a servant, she was indeed part of magic, and her thought process did not necessarily conform to any logic or rationality.

Moreover, Alexandria is in Egypt, and Euclid may have had some contact with Atlas.

"By the way, Eri, did the person who named you know Greek?"

"……what?"

Eri looked at Euclid, who had transformed from a gloomy mathematician into a cheerful young lady, with a puzzled expression. She wasn't quite sure who had named her; she had had this name since she could remember, that is, since she met Chitose, so she shook her head.

“It seems not.”

"Oh, then never mind."

"...What's wrong? I'm curious about why you're acting this way."

Although Erise intended to agree with Euclid's topic, she also realized the budding curiosity within her.

"It's nothing serious, it's just the pronunciation of your name, Erise—"

"pronounce?"

Before Euclid could finish speaking, Eri interrupted her instinctively.

She vaguely remembered that during the Holy Grail War when she was eight years old, when she finally won the championship against Jue Karna, the Demon King had said the same thing to her.

“The pronunciation of my name evokes the land where heroes reside after death. The formal name would be Elysium, but in French, éLyséEs means the same as Elysium.”

After hearing Eri's fluent explanation, Euclid hesitated before speaking:

"...I never expected that a middle school student who skips school all the time would know these things. This is not Euclid at all."

"...because someone told me."

"Oh? Did the person who told you about the Champs-Élysées in France? The original French word Champs-éLysées means the blissful paradise where heroes return after passing through the Arc de Triomphe."

Upon hearing this, Erise, leaning back in her chair, gave a bitter smile: "He... is no longer here, so he never said that."

"Is he—Erise, your father?"

"No, he was a guy who died a long time ago."

"...I'm sorry, if you have the chance, you can ask Bonaparte about the details."

Euclid could tell from Erise's poor performance that the Demon King was very important to her, probably a Servant or something similar.

"I will, and I will study hard at school, Euclid."

The girl, who had been talking non-stop, suddenly looked gloomy. Although she had a smile on her face, there was a hint of loneliness in her eyes.

“Erise is just a middle school student, it’s already quite impressive that she knows this much, Euclid.”

"what……"

Euclid trembled at Novia's words, immediately lowering his head timidly. "I'm so sorry, it's my fault. You, you really did a great job. Please forgive me, Lord Death, thank you for your forgiveness..."
