Shirou, who returned from the Fairy Kingdom

Shirou slept soundly.

This was probably the most comfortable night's sleep he had had since he started to get used to Japanese-style living.

Training familiars, setting up barriers, and performing descent rituals—Shirou's recent work had left him with a severe shortage of magical energy, but after a good night's sleep last night, he had completely replenished it.

"Has my magician skill improved? Okay~ I'll work harder from today onwards!"

Shirou walked briskly into the living room.

"Ah, Master, good morning~ Did you sleep well last night?"

I heard a clear, melodious, heavenly female voice—

Ms. Avalon sat gracefully at the dining table, looking over with a smile.

Shirou: "What happened to the promised spirit form?"

Just then, another female voice came from behind: "Ah, so sleepy... Good morning, Shirou."

Shirou's eyes widened immediately: Oh no! Fujiwara is here, she'll be seen by Fujiwara!

Without thinking, the boy pounced on Ms. Avalon and pinned her down.

"Quickly transform into a spirit form!"

"...Shirou, what are you doing there?"

Fujimura Taiga blinked, then asked in a daze, "Why would you roll around in a place where no one is around?"

"what?"

Shirou looked at the silver-haired beauty beneath him with a puzzled expression.

Even though Ms. Avalon had not become a spirit, Sister Teng seemed to be completely unable to see her.

"Hoo hoo hoo, Master is really hot-blooded, isn't he? Attacking someone first thing in the morning?"

Ms. Avalon covered her mouth and chuckled.

"?"

Shirou then noticed that his hands were deeply embedded in a pair of full, soft...

Volume 1, Chapter 32: "The King's Command Spell" (4/6)

"Whoa!!!"

Shirou quickly withdrew his hand and jumped backward.

Ms. Avalon grinned mischievously: "Oh dear, what a pity, it would have been fine to continue."

"How could we possibly continue?!" Shirou shouted, his face flushed red.

Fujimura Taiga leaned closer and asked, puzzled, "Shirou, who are you talking to?"

As expected, I can't see it at all...

Despite the presence of a stunningly beautiful woman in the room, surrounded by vibrant flowers, Sister Teng remained oblivious.

There is no doubt that this was Lady Avalon's doing.

Skills... no, magic?

It's many levels above Shirou's hint magic.

While it's unclear whether it will be effective against enemy mages and Servants, it's certainly more than enough to deal with ordinary people like Fujiwara.

This will be tough on Shirou.

In other words, Ms. Avalon can now walk around her home openly and without fear.

While eating breakfast, Fujimura Taiga asked while drinking miso soup:

"What's wrong with Shirou today? He's been sneaking peeks at places where no one is around since just now."

"Hmph, Master, so you've been spying on me all along?"

For Shirou, the first morning of Lady Avalon's stay at the Amamiya residence was a hellish start.

Will this continue until the Holy Grail War ends?

Shirou sighed in despair.

But then again.

It's so soft and smells so good...

……

……

The back row of an empty classroom in the elementary school section of the private Homurahara Gakuen.

"Let's now begin the first Holy Grail War operational meeting."

After Shirou made this announcement, the silver-haired beauty sitting opposite him clapped excitedly.

"Clap, clap, clap..."

The materialized Lady Avalon clapped her hands and smiled as she bent down to ask another advisor from Amamiya's faction.

"Mr. Machiri, why aren't you clapping?"

Toy rubber duck: Do I look like I can clap my hands?

Shirou raised one hand to signal for silence, and then, as the meeting's moderator, summarized the current situation.

First of all, although our side is participating in the war, we do not have any Servants who are able to fight.

"Sorry~?" Ms. Avalon winked.

Although she cannot participate in battles, she can provide Shirou with very powerful support and enhancements.

Lady Avalon's enhancements could even allow the physically fragile Shirou to fight against Servants for a short time, but it was not a panacea and had significant side effects.

Furthermore, if the Master loses, the entire game is lost, so never fight a Servant unless absolutely necessary...

"Wait a moment."

The little yellow duck stopped Shirou from speaking.

He sensed something was off about what she had just said.

Machiri asked suspiciously, "Kid, what exactly is this woman's 'enhancement'? And what are the side effects?"

"...Well."

Shirou looked at the Command Seals on the back of his right hand.

"Hey! Kid! What's with your Command Seals?!"

Machiri shouted, this was the first time he had been so agitated since losing his physical body.

The Command Seals on the back of Amamiya Shirou's hand had changed from the shape he had initially seen.

The color also changed from its original bright red to an ominous blackish-red. What could this be...?

"Let me explain."

Lady Avalon knelt down in front of Shirou, smoothing her skirt, and took his right hand in her hands.

"I have magically modified Master's Command Seals, so Master can now use Command Seals to enhance himself."

"Not an enhanced Servant, but an enhanced mage himself? How is that possible!"

Machiri, the creator of Command Seals, roared, but Lady Avalon continued, unperturbed.

"Furthermore, I have already pre-embedded the specified program inside the Command Seal."

To maximize the efficiency of the Command Seals, a single trigger effect was assigned to them.

The specific enhancements are as follows:

"Within three minutes, rapidly grow Master's physical body to the state of 18 years later—10 years from now."

"Varied……"

Ms. Avalon tilted her head adorably: "It's more accurate to call it a 'transformation' than 'growth'?"

If the battle lasts longer than 180 seconds, Master will revert to his current child form.

Ta-da! I've named this mechanism "Dead Count Shapeshifter".

As the name suggests, the side effect is the Master's life; each Command Seal consumed brings them closer to death.

By the way, personally, I still prefer Master's current appearance, oh my, so cute~!

"Whatever your thoughts are, that's fine with me."

Shirou pushed away Ms. Avalon's hand that was pinching his cheek.

"........."

On the other side, Machiri was speechless.

Even though I had lost both body and soul, I felt as if I were experiencing a chilling sensation that soaked my back and a bone-deep dread.

He was stunned by the extraordinary talent of the female magician before him.

Despite being a Servant who only arrived last night, she bypassed the Holy Grail's control, cracked the Command Seals' mechanism, and even completely modified the Command Seals in just one night!

It would be impossible to achieve without an extraordinary level of magic.

Could the other party be a magician from the Age of Gods?

No, even a magician from the Age of Gods couldn't do that!

Those who can achieve this level are already qualified to be called Grand Masters...

"Kid, do you think this is okay?"

Admiration and fear are two sides of the same coin.

On the other hand, Machiri sensed a deep malice in the woman's actions.

"Hmm? It's okay."

Shirou tilted his head innocently: "Even if it's only for three minutes, it's enough to strengthen myself to the point where I can fight Servants."

"That's not what I meant!"

The little yellow duck said angrily, "This is not a business without capital; it is essentially a loan."

To force oneself to grow to the state of ten years in the future through magic is tantamount to incurring debt in advance!

This cannot be considered a blessing at all; it is a curse that will only lead you to deeper destruction and decline.

"But isn't this what they call a 'miracle'?"

Shirou said it as if it were the most natural thing in the world.

The most powerful and incredible magic he knew: Morgan's transference of spirit particles.

That was a miracle that led to the realm of magic.

With a simple wave of his staff, he can send enemies from the present into the past.

Real-world time travel—

It sounds wonderful, but it's actually just forcing current debt onto past borrowing.

What Shirow did next was no different from Morgan's actions.

"There are no free 'miracles' in this world, so as long as you can accept the cost, I have no objection."

Shirou spoke with an incredibly arrogant tone, leaving Machiri speechless.

Indeed, even the five great magic spells could not eliminate entropy increase out of thin air.

However, "being able to understand" and "being able to easily accept" are two completely different things!

This kid...

“I do not agree to this operation,” Machiri said coldly.
