Shirou, who returned from the Fairy Kingdom

Under the wise rule of Queen Morgan, Britain will become a gentle land, a paradise full of joy, happiness, equality, and beauty.

Although it was extremely difficult to achieve, Shirou believed that if she was kinder than anyone else, she could definitely do it.

Because this is Shirow and Morgan's... ideal world.

……

……

"Ugh……"

Shirou sighed and walked out of the bedroom into the living room.

In the end, they still didn't understand why it was chosen by the Command Spell.

Today is Sunday, there are no classes at school, so it should be okay to be a little lazy.

Let's just drift through the morning in a daze, and then gather Matou Tsuruno in the evening to discuss countermeasures further.

"Shirou! You're up so late, I'm starving!"

Fujimura Taiga tapped his rice bowl rapidly with his chopsticks, urging him impatiently.

"Good morning, Shirou-nii-san, I'm here to play."

Matou Sakura sat calmly, just like any other member of the family, and gave him a sweet and lovely smile.

Shirou: "..."

The eight-year-old boy felt the weight of being the head of a family for the first time after returning to this world.

The place you've finally found to stay is one you must protect.

While this may not be called a wish, the desire to protect everyone is genuine.

……

……

Shirou is not the type to escape reality.

With several months to go before the official opening, and since the Command Seals have already manifested in my hands, all I can do is prepare actively.

First, preparations for summoning Servants.

Secondly, investigate the other participating magicians, and monitor the only known enemy at present—the Tohsaka family.

Thirdly, a barrier was set up near the Amamiya residence to construct magical defensive fortifications.

With Machiri's help, the second and third points are not a problem, but we should not rush things.

So let's get back to the most fundamental question.

The principle of the Holy Grail War is Servant vs. Servant.

Servants are the fantasies of the greatest and most powerful heroes in human history (Phantasm).

Faced with that absolute power that far surpasses that of humankind, even the most outstanding magician can only act as a commander and assistant.

According to Zouken, summoning a Servant requires a corresponding catalyst, which is a Sacred Relic.

For example, weapons used by warriors in their lifetime, armor worn by generals in their lifetime, and so on—things that are connected to the servants themselves.

Most Masters prepare their favorite artifacts when participating in the Holy Grail War because mages extremely dislike uncontrollable factors.

While you can summon Servants without preparing Sacred Relics, you have no control over what kind of monsters or demons will appear.

Although Shirou gradually learned about the history of this area through six months of elementary school education and daily life, he still couldn't understand:

"Who exactly can be considered the strongest Servants?"

Upon hearing this question, Machiri remained silent for a moment before saying, "Kuku, actually there's another law in the Holy Grail War that can't really be considered a rule—Saber is the strongest and most outstanding class."

"Is that right?"

Sword! Weapon! The strongest!

As someone destined for the sword and once the strongest swordsman in the Fairy Kingdom, Shirou was quite pleased to hear this.

Did you hear that, Morgan? I am the strongest!

Throughout history and across cultures, humanity has placed immense imagination on the sword, always regarding it as an object of unparalleled prestige.

The little yellow duck continued as if reciting a familiar list: "The world-destroying fire sword Levantine and the strongest magic sword Gram from Norse mythology, and the twilight magic sword Balmongk from German legend."

Charlemagne's legendary sword, Gouvayus, originated from the Greek mythological sword Durandal and the Japanese mythological sword, Ame-no-Murakumo.

Each of these is a Noble Phantasm capable of destroying the world, and the hero who wields it is naturally among the strongest.

Shirou was completely bewildered: he had never heard of any of the famous swords that Machiri mentioned in Britain.

Okay, if I have the chance in the future, I'll add them to my own "domain".

"Then, among the best classes in this Holy Grail War, there is only one who can be widely recognized as the strongest Saber."

Shirou asked curiously, "Who is it?"

Then, Machiri uttered a name that he missed dearly.

"King Arthur."

P.S. I recommend a book written by a friend; it's currently on sale, so you might want to check it out.

I haven't seen it, but my younger brother saw it and kept praising it.

My Mother Sajou Aika

Volume 1, Chapter 27: Alice: I Have a Dream

On a frozen wasteland in Germany, there stands an ancient castle that is perpetually sealed off by ice, snow, and barriers.

Living here is the legacy abandoned by the disciples of the Third Mage—the homunculi race known as the Einzberns.

Although the humans who created them are probably long gone, the androids have not forgotten the great aspirations that their creators pursued.

The reappearance of the third magic.

To make the miracle a reality, they traveled to the far east two centuries ago and formed a partnership with two magicians there.

This is the origin of the Holy Grail War and the founding three families.

It was the end of 1993, and the once-in-sixty-year cycle of fate was about to begin again.

Having experienced a crushing defeat last time, Einzbern made unprecedented preparations this time and was prepared to gamble everything.

The chapel of Einzbern.

Beneath the stained glass depicting the long history of the androids' pursuit of the Holy Grail, two figures are conversing.

One of them had dazzling silver hair that reached her waist and fiery red eyes that seemed to burn.

The pure white dress couldn't hide her voluptuous and graceful figure; her dignified beauty exuded both the innocence of a young lady and the mature elegance of a noblewoman.

She is none other than Irisviel von Einzbern, the Master who represents Einzbern in the war.

The history of Einzbern dates back to the first year of the Gregorian calendar, which is 2000 years ago.

In the long span of 2000 years, a miraculous individual was born by chance, one whose existence cannot be replicated.

Known as the "Winter Saintess," Justessa Rislesi von Einzbern is capable of wielding the Third Magic.

Then, there was Irisviel, the girl who reached the pinnacle of Einzbern on a different level from Justessa.

She is the pinnacle of two thousand years of technological accumulation by the artificial human race.

It possesses ultimate performance that was completed ten years ahead of schedule, and like that saintess, it is probably difficult to replicate.

If even she cannot obtain the Holy Grail, then the Einzbern family will voluntarily abandon their millennia-old wish and bury everything in the blizzard.

The one who is talking face-to-face with Irisviel at this moment looks a little smaller.

That flawless, androgynous face might be mistaken for a blond, handsome young man at first glance, but upon closer inspection, one can discover the girlish charm hidden beneath that dignified demeanor.

Saber, the strongest trump card prepared by the homunculus race for the Fourth Holy Grail War—

King Arthur, Artoria stared at "that" the maid brought out and asked:

"Irisviel, what is this...?"

The silver-haired android gave a mischievous, childlike smile: "Saber is asking a question she already knows the answer to again."

"Shouldn't you know best what this is?"

Saber hesitated for a moment, then nodded and said, "This is the scabbard of the Holy Sword, the catalyst you used to summon me into the real world."

"Correct answer! Saber is such a clever child!"

Irisviel clapped her hands happily, while Saber frowned and said seriously, "Please don't treat me like a fool, Irisviel."

"I'm sorry, I'm sorry, I was just kidding, don't be angry."

The scabbard of King Arthur's most famous weapon, Excalibur.

Merlin, the king's magician and the first prophet of Type-Moon, once left behind this famous quote:

"The truly powerful weapon is not the holy sword itself, but its scabbard."

If this statement is true, then the scabbard even possesses power surpassing that of the Star Holy Sword.

Legend has it that King Arthur lost his sword sheath due to the treacherous schemes of his sister, the enchantress Morgan yoke.

As expected, the king, now without the protection of his sword sheath, soon died in battle due to the rebellion of his son Mordred.

Upon seeing the long-lost scabbard, Saber was overwhelmed with emotions. At that moment, Irisviel spoke.

“I intend to give it to Saber to use.”

"……what?"

Saber stared wide-eyed in disbelief: "But didn't we agree to protect you with the scabbard?"

After nearly half a year of getting to know each other, she has come to realize that her master is a willful, whimsical, and eccentric young lady who loves novel things.

But wasn't this decision a little ill-considered?

Irisviel nodded and said, "That's what my great-grandfather said. He said protecting the Lesser Grail is the top priority."

But after thinking it over, I decided to give it to Saber.

Because you see, the scabbard can only unleash its true power in the hands of the king, right?

She was actually hiding a fact.

The Einzbern family did not hand the scabbard to Saber not because they intended to use it to protect their Master, but because they were wary of Saber.

After all, the three founding families would eventually have to sacrifice their own Servants, so it was impossible for them to give the strongest scabbard to the strongest Servant.

What if we can't kill it in the end?

King Arthur, protected by the sword sheath, is literally invincible in a physical sense!

Irisviel also concealed the dark truth of the Holy Grail War from Saber.

She felt very guilty about this, but even so, she still wanted to believe in Saber.

Even if people say she's too naive, Irisviel believes that there should be mutual trust between master and servant.

Even though there are still 6 enemies, you're only thinking about how to sabotage your own servants. How can you possibly win in the end?

After much deliberation, Saber shook his head: "I don't think Ahadeon would agree."

But then they heard their Master say with a rare solemn expression, "This is a battle between me and Saber, and has nothing to do with my grandfather."

"Won't you get scolded later?"

"Saber will get scolded along with me then, huh? Heh."

"..."

Saber was unaware of the Einzbern family's intentions, but she sensed boundless trust in her Master's crimson eyes.

Artoria took the sword sheath and uttered a simple yet sincere vow of gratitude.

"Irisviel, it's so good that you are my Master. I swear by my sword that I will protect you until the very end."
