===

The golden light gradually shifted in shape, and soon, it transformed into a sacred, noble-looking spear.

The Sacred Armament was an ability Agumon awakened after evolving into her Mechanical Dragon form and solidifying her foundation.

In Sacred Armament mode, Agumon could unleash her full potential, which transcended the boundaries of this world!

After unleashing her true power, Agumon had two modes: Sword Mode and Spear Mode.

What Akira was using now was Agumon's Spear Mode!

Whether it was the Gauntlet of the Red Dragon Emperor or the Wings of the White Dragon Emperor, they could only push Akira's power to its limit. Going beyond that would cause fundamental damage to his body.

However, Agumon's Sacred Armament was different.

Agumon's Sacred Armament could directly overlay her power onto Akira!

After Akira used the Dance of the Red and White Dragons to push himself to his limit, he could further surpass that limit through the Sacred Armament!

In Sacred Armament mode, Akira felt no strain, even when wielding power at the peak of the demon king level.

This was the overwhelming strength of the Sacred Armament mode!

"Extremely dangerous... beyond dangerous!"

Saber immediately distanced herself from Akira!

Just moments ago, she could clearly sense Akira's presence, but now, something had changed.

After the golden spear appeared, even though Akira was right in front of her, Saber could no longer sense any trace of his energy!

This distortion of perception was far more terrifying to Saber than any overwhelming power!

Akira shook his head and slowly walked toward Saber.

After Agumon awakened the Sacred Armament, Akira had tested its strength.

Now, even with the Twelve-Winged Fallen Angel Avatar, Agumon's Sacred Armament remained Akira's strongest trump card!

Facing the approaching Akira, Saber's gaze sharpened, and she gripped her holy sword tightly.

"Haahhh!!!"

[Invisible Air!]

"Boom—"

A powerful gust of wind erupted, sweeping across the ground and rushing toward Akira!

[Whoosh—]

A sound reminiscent of Accelerator's ability echoed.

Before the wind could even reach Akira, Saber's Invisible Air dissipated on its own!

"What?!"

"There's no need to be surprised," Akira said as he continued forward.

"Saber, you're a battle-oriented Servant. You know how to use tools called Noble Phantasms, but you don't understand the principles behind their creation."

"In my world, most people must have a deep understanding of magic. Otherwise, they can't even use it properly."

"Knowing how to activate magic naturally means knowing how to dismantle it!"

Akira's words were correct.

However, instantaneous calculation and dismantling required an immense amount of magical knowledge and computational power, which Akira couldn't achieve on his own.

But with the Sacred Armament, Akira could directly tap into Agumon's vast knowledge and computational abilities!

Combined with his Eye of Insight, Agumon's magical knowledge, and computational power, Akira could achieve this feat!

"Haahhh!!!"

Saber pushed aside her doubts and stepped forward, raising her holy sword to meet Akira's spear.

However—

"Clang—"

The sound of metal clashing echoed.

After the collision, Akira's spear spun at an unnatural angle, aiming straight for Saber's neck!

"What?!"

Saber's sword erupted with a powerful gust of wind, barely allowing her to dodge.

"What was that just now?!"

Saber was shocked.

If it were just a physical collision, such a trajectory would be impossible!

"It's nothing. I just set up a spell on the spear before the collision. Once a certain part of the spear is struck, it triggers an internal force, causing the spear to shift. That's all," Akira explained as he continued to advance with his spear.

"Sounds simple when you say it like that..."

Saber broke out in a cold sweat.

If she hadn't activated Invisible Air earlier, the spear would have left a bloody mark on her neck.

Was this precise control also part of Akira's calculations?!

To test her theory, Saber launched another attack!

This time, Saber didn't use any fancy techniques—just a straightforward slash!

"Clang—"

The holy sword and the sacred spear collided, and the same thing happened again!

Facing the spear's sudden twist and acceleration, Saber intercepted it with her sword.

Then—

"Clang—"

Another metallic clash.

Saber barely managed to block the spear aimed at her delicate neck.

Unfortunately, while she could block the second strike, she couldn't block the third.

The spear shifted its trajectory again, aiming for Saber's neck!

[Whoosh—]

Invisible Air erupted once more.

However!

This time, as soon as Saber's Invisible Air activated, she heard the same sound as before.

The wind dissipated instantly, and the spear continued its path unimpeded!

In Saber's eyes, even though she had retreated with all her might, the spear still accurately grazed her neck.

"Tch—"

Saber retreated several meters and touched her neck.

Sure enough, a thin line of blood had been drawn.

Seeing this, Saber puffed out her cheeks in frustration.

"During our fight, you used the same amount of force as me..."

"But with your absolute calculation skills, you completely overwhelmed me, like an adult toying with a child."

"Do you find it fun to tease me like this?!"

As she spoke, Saber's ahoge swayed cutely, making Akira want to pluck it off.

"Saber, you guessed right."

Akira smiled happily.

"It's because your reactions when being teased are so adorable!"

"So, to see more of that cuteness, I have no choice but to tease you a bit more."

"Hmph!"

What a perverse sense of humor!

Saber pursed her lips.

This kind of mischief was exactly like the demons from myths!

Although she was unhappy, Saber had to admit that, in terms of combat skills, Akira had completely crushed her.

Even if she regained all the power she had in her prime as a Servant, she would still be far from matching him!

Because regaining her power only increased her combat ability by a small margin, while Akira's skills were on a completely different level!

After a moment of thought, the golden-haired maiden raised her holy sword again, attempting to break through Akira's defenses with her own skills.

"Haahhh!!!"

Saber let out a soft cry, her clear voice echoing alongside the clashing of the holy sword and spear.

She didn't complain about Akira using spells on his spear, as that would be hypocritical.

After all, she had used Invisible Air herself.

Demanding that Akira fight her in pure melee combat just because she was at a disadvantage would be too shameless. She wasn't that kind of person.

In a fight, reach mattered. To defeat a spear with a sword, one needed overwhelming skill.

But in this case, Akira's skill far surpassed Saber's.

Saber's attempt to rely on her instincts and talent to overcome this gap was, in Akira's eyes, like a blind person trying to read an electronic book with Braille—utterly futile!

"Saber is Saber, so stubborn," Akira shook his head.

However, since Saber wanted to play, he was happy to oblige.

And so, Akira and Saber continued their duel without using any special powers.

Even the strength Akira used was precisely matched to Saber's!

Finally, after hundreds of failed attempts to outmaneuver Akira, Saber gave up!

Even when she deliberately held back or stopped resisting, Akira could still leave a thin line of blood on her neck without seriously injuring her!

This wasn't a duel—it was pure teasing!

[Invisible Air!]

Saber unleashed Invisible Air at full power, almost as if she was giving up.

Then...

"Whoosh—"

The wind died down almost instantly.

As soon as the breeze started, it was immediately dispelled!

Noticing the change in Saber's mood, Akira narrowed his eyes and used Instant Movement to appear in front of her.

[First Secret Technique: Rhino Strike!]

A powerful force transmitted through the spear, and Saber's holy sword was knocked out of her hand!

"What?!"

Saber quickly retreated, glancing at her sword and then at Akira, looking like a child who had done something wrong.

Earlier, Akira had used far more strength than she had.

She knew why... her half-hearted attitude had displeased Akira.

So, after her sword was knocked away, Saber felt lost.

She didn't know what to do.

"What's wrong? Aren't you going to pick it up? I'll allow it."

Akira narrowed his eyes, showing no intention of pursuing her.

Akira allowed Saber to retrieve her sword.

It was like a master allowing a puppy to fetch a thrown toy.

This was... part of the training process.

Saber remained silent for a few seconds before quietly picking up her sword, her heart heavier than ever.

Her swordsmanship had been honed through countless battles, almost reaching the realm of "mastering one technique to master all."

But even so, she was no match for the young man before her.

Whether it was skill or equipment...

No.

What had been crushed was only Excalibur.

If it were Avalon...

Would Avalon make a difference?

Now, even Saber wasn't confident about Avalon.

Seeing Saber like this, Akira smiled faintly.

Continuing to tease Saber like this wasn't fun anymore. He didn't want a King of Knights with a broken spirit.

That kind of King of Knights wouldn't be as satisfying to conquer.

So, Akira raised his sacred spear, ending the training game.

It was time... to move to the next stage!

"Saber! Since you're no longer in the mood to play, let's move on to the next stage!"

"As you said, to change history, one must possess power that surpasses the world's will!"

"With your world-class defensive power, you are the perfect candidate to test this!"

Akira raised the Spear That Pierces the World and chanted its true name in his heart:

[Spear!]

[The True Holy Spear That Pierces the World!]

[Draw upon the power of awakening and the principles of existence within me—]

As Akira chanted, the entire mirror dimension was filled with golden light!

Countless golden threads flew in from the outside world and then flew out again, as if connecting countless realms!

"I understand! I will test this properly!"

Before Saber, the golden sheath of Avalon appeared, radiating a holy light.

After escaping the one-sided combat, Saber regained some of her spirit.

In terms of skill, Akira was undoubtedly a monster. But what about his Noble Phantasm?!

[Pierce through the boundary between this world and the infinite worlds—]

[You!—]

[Transcend truth and become light!—]

[Avalon! (Distant Utopia)!]

"Clang—"

The holy spear and the golden sheath collided.

The golden light shattered everything!

This golden light—it came from the holy spear!

Kiritsugu was blinded by the golden light.

When he opened his eyes, he found himself back in the real world.

Saber looked around, feeling somewhat dazed.

"Wait... wasn't I using Avalon to block the spear? How did I end up back here?"

Before Saber, Akira calmly sat down and poured himself a cup of tea.

"Saber, to avoid destroying Avalon, Agumon redirected the spear's power to the mirror dimension."

"Now that the mirror dimension has shattered, we've returned to the real world."

"To avoid destroying Avalon?"

Saber looked down at Avalon in her hand.

Avalon was unharmed.

But something even more unsettling had happened!

On Avalon, a golden mark of the holy spear had been engraved!

How was this possible? Being destroyed would have been understandable, but how did a spear mark appear?!

Saber panicked.

She was like a girl who woke up to find a heart-shaped mark on her stomach, frantically trying to wipe it off.

Soon, Saber gave up.

Forget it...

This was just how it was.

She was just a Servant, after all. She didn't have the right to question the whims of a being who transcended worlds.
