Shirou, who returned from the Fairy Kingdom

"Teacher, what should I do?"

Shirou sat upright in front of Lady Avalon, but she looked hesitant.

"Hmm... never mind, Shirou, you probably don't want to."

"I'd do anything to go back!"

"really?"

"Yes."

The red-haired boy nodded resolutely: "I must go back."

Ms. Avalon met his gaze, and after confirming his understanding through her eyes, she nodded.

"Next, I will explain the method."

"Please say."

Lady Avalon said, "Don't forget, Shirou, although you are human, you are also a Servant."

Even if the physical body is destroyed, it can simply be replaced with a new Servant's body...

When the Holy Grail War ends and you return to your own world—

They will then revert from their Servant state back to normal humans due to world corrections.

Shirou pondered: "That's true... In other words, I just went from being a 'Servant who can't become a spirit' to an 'ordinary Servant'."

So, how exactly should this be done? How can the Servant's body be rebuilt?

"Normally it would be impossible, but fortunately this is the 'paradise' of planetary dreams."

"Shirou only needs to replenish enough pseudo-spiritual particles... and use the soul as observable energy to create a Servant body (spirit body) that belongs to you."

So where do we replenish our pseudo-spiritual particles? That's what I'm asking right now.

Having lost his physical body, Shirou lost his magical connection with Ayaka Sajou.

If it weren't for the fact that Utopia is a place where the souls of planets are kept—he should have been completely destroyed.

The Flower Magician tilted her head and looked at Shirou for a moment, then spoke with a smile:

"Spiritual particle synchronization... that is, the method of replenishing magical energy, Shirou, aren't you the most familiar with it?"

It's very simple—all you need to do is hug a woman.

"Wait……"

A bead of cold sweat trickled down the red-haired boy's cheek.

"What good luck, Shirou..."

Ms. Avalon covered her mouth and chuckled.

"Perfect timing, right in front of you is a lovely and gentle older sister who will do anything for you."

The other party is not only a genius magician in the amusement park, but also someone you've had experience with exchanging bodies with—

There is absolutely no need to worry about physical compatibility between the two individuals.

"Wait... wait a minute!"

Didn't we already agree that this would be the first and last time?

During the Fourth Holy Grail War, Shirou did indeed hug Lady Avalon once.

However, that was a necessary replenishment of magic power for the final battle.

At that time, Shirou was very weak, and that was the only way he could defeat Gilgamesh.

After the Fourth Holy Grail War, Shirou never again engaged in any ambiguous behavior with Lady Avalon.

Over the years, he has always regarded Ms. Avalon as a teacher who, although unreliable most of the time, is still trustworthy and respectable.

Now that things have come to this, how can we possibly repeat the same mistake?!

The Flower Magician curled his lip: "What... just now he was so confident that he was willing to do anything."

If you're unwilling, then just pretend I never said anything.

Whether Shirou is in spirit form or back into a human form, it doesn't matter to me.

Well, I have something to do later, so I'll be going now..."

Just as Ms. Avalon was about to get up from the grass, Shirou grabbed her.

"I understand—all I need to do is do it, right? I'll do it."

Although engaging in that kind of behavior with the teacher again was not my intention...

But if it's to return to the world he once was, Shirou wouldn't mind doing anything.

"..."

The light that shone from the red-haired boy's eyes startled Lady Avalon; it was the first time she had ever seen Shirou with that expression.

Wow, that's really strong...

A slight pain came from the wrist that was being tightly gripped by Ms. Avalon.

It was the same when he roughly grabbed my shoulder just now.

Compared to back then... you've really grown a lot...

Both his strength and physique are now vastly different from what they used to be...

Ms. Avalon swallowed, feeling a warmth rising from deep within her lower abdomen.

You're not a child anymore, my Arthur...

She had initially been somewhat hopeful, but suddenly began to feel fear.

After all, the Fourth Holy Grail War was Lady Avalon's first and only "experience".

In other words, the only person the Flower Magician experienced was Shirou, who was still a ○○ student at the time.

Now she has to face Shirou, who is already fully developed... and has more energy than a normal male.

Having many lovers and partners, he holds an impart every month at the Western-style mansion on the mountain, honing his skills in that area to perfection over the years.

Faced with her disciple who had undergone a complete transformation, the female magician couldn't help but feel afraid.

Compared to the experienced Arthur, wasn't she no different from a little girl?

Ms. Avalon said in a panic, "Ah... although I have experience with spirit synchronization, you have to follow my rhythm from now on... Ah~! Listen to me, Shirou!"

Before he could finish speaking, Shirou grabbed the Flower Magician's shoulder without giving him a chance to speak.

"I'm sorry, teacher... I'm going to do my best now."

"what?"

Upon hearing this, Ms. Avalon turned pale.

"Wait...wait a minute, this position is so embarrassing, I don't like it...can we try something else..."

The Flower Magician's cheeks flushed red as she struggled desperately, shaking her long, beautiful legs.

But how could she possibly match the strength of a boy in his adolescence?

Moreover, Shirou is somewhat out of his mind right now.

"No...please, Shirou...be gentle, don't be so rough..."

As a result, what befell Ms. Avalon was—

It is a powerful and merciless outburst, brimming with Shirou's absolute belief that "I want to go back!"

……

……

"Thank you for your help, teacher... Well then, I'm ready to go."

Shirou glanced at Lady Avalon behind him.

Just over an hour ago, she was a stunningly beautiful woman, as delicate as a flower. Now, she has no ladylike demeanor whatsoever and lies sprawled on the grass like a frog.

"........."

Shirou moved his hands and feet.

Although it feels strange, this is probably what the teacher meant by "a body composed of pseudo-spiritual particles".

Shirou is no longer a human Servant who cannot be spiritualized like Saber during the Fourth Holy Grail War; he has become a true Servant.

Since there is no record of Shirou in the Holy Grail War, he can return to his original world as a human once the Holy Grail War in Romania is over.

Of course, the problem that needs to be solved before that is "returning to the surface of the planet".

Shirou originally intended to have Ms. Avalon help him send her back, but unfortunately, she is currently completely unable to move and is in a state of delirium.

To go to such lengths to help your student... Thank you, teacher.

Shirou wiped away non-existent tears from the corners of his eyes.

Even for the sake of Ms. Avalon, I can no longer rely on her. This time, I must get out of this predicament on my own!

In most of the works Shirou has read, the escape method in this situation is fixed.

That is—to forcibly open a hole in space!

Shirou drew a Japanese sword with a black scabbard from thin air.

"Yamato"

Like the "Blade of Chaos," it cannot be used when Shirou manifests as Saber Arthur Albion.

However, in this ideal world, Shirou somehow became able to summon and use them.

This knife possesses the characteristic of "separation," capable of not only cutting through space but also creating dimensional tunnels through which people can pass.

Generally speaking, Shirou doesn't use the sword's special abilities casually.

In a sense, the demonic nature hidden within the "Yamato" is even greater than that of the "Chaos Blade"—

In other words, it is a demonic sword that will bring disaster to its master.

Wasn't there a man in this country's history named Muramasa or something?

But now I don’t care about that much.

I need to hurry back. I don't even know how much time has passed outside while I've been in this idyllic place for so long.

Shirou drew his sword and drew a cross in front of him, where there was nothing.

With just a slight tremor, the void within the Starry Sea was torn apart.

The void rapidly expanded, forming a dark cave that people could pass through, with the surrounding spacetime constantly pulsating.

Shirou immediately seized the opportunity and stepped into the newly formed rift.

The cave lasted only a moment, closing the instant he entered, but Shirou felt an overwhelming surge of joy.

Speaking of which, I looked absolutely incredibly cool in that scene just now... I really want Jeanne and Aika to see it too.

When we get back, we'll put on a circus performance for Sakura and Illya.

Volume 5, Chapter 237: Morgan makes a limited-time return; Caster Artoria makes her first appearance.

"Saber!"

"Huh...?"

Shirou noticed that the "Black" cavalryman grabbed his wrist anxiously.

It seems I have safely returned to the surface of the world from Avalon.

However, something just feels off... What exactly is this inexplicable and intense sense of unease...?

"What are you daydreaming about!" Astolfo shouted.
