Type-Moon, What Do You Mean You summoned Tiamat?!

A dazzling golden magical light was unleashed toward the sky, piercing through the barrier inside Chaldeas almost instantly and without any obstruction.

At this moment, the physical boundary between this pseudo-planet and the real Earth seemed to have been completely blurred by this all-encompassing light.

The vast, sea-like golden magic transformed into a raging hurricane that swept across the entire region.

Even Gilgamesh, who had been coldly observing, and all the Beasts present felt an unprecedented terrifying pressure that shook their very souls at this moment.

Marisbury, who had a "conceptual connection" with Chaldeas, was directly blown away by the aftershock of that terrifying energy explosion. He crashed through multiple walls, slammed into reinforced concrete, and created a shocking human-shaped crater.

Goetia's expression changed. It immediately unleashed an intense beam of light toward the front, powerful enough to burn away human history.

The magnificent golden halo suddenly transformed into a massive and sturdy shield. Its vigilant posture was as if it feared the sharpness of the Star Sword was being directed straight at it.

After all, Goetia had personally experienced the true power of the Star Holy Sword when it confronted the ancient existence possessing Matou Yuu, so it naturally understood better than anyone what that light signified.

However... The situation this time was completely different from before.

Goetia's gaze was fixed straight on the water mirror floating in the air and the young man inside the mirror who was raising the holy sword high with one hand. Its deep crimson beast eyes were filled with surprise.

It knew very well that during the previous battle in Snowfield City, the ancient existence lurking inside Matou Yuu had temporarily awakened and used his body to draw the holy sword.

But this time... Without any assistance, Matou Yuu had unleashed the Complete Liberation form of the Star Holy Sword on his own!

Yes, there was no doubt — that was unmistakably the radiance of a star.

At this moment, the aura emanating from Matou Yuu was no less than that of a typical young Beast. Combined with the fully unleashed star-forged weapon... Thinking this, Goetia couldn't help but inwardly curse.

Why does this sword recognize a human?!

It should be noted that Matou Yuu had originally been just an ordinary magus. Logically speaking, no matter how skilled a magus was — even if they reached the level of a "magus" who had reached their Origin — they could never shake this holy sword, which symbolized the foundation of the planet, without the approval of the planet's will.

But now, the holy sword that Matou Yuu had unleashed in his hand revealed an undeniable fact... A "human" who should have been rejected by Gaia and guarded against by the Counter Force had actually become the wielder of the Star Holy Sword!

Goetia even suspected that there might have been an error in its spiritual origin calculations.

At this very moment, the most deafening silence throughout the entire arena belonged to Crimson Moon, who was lurking inside Matou Yuu's body.

She, who had been confined for so long without being able to breathe fresh air, had finally gotten the chance to possess Matou Yuu. She had used the sword to show off her power and had even given Artoria instructions on the proper way to use the holy sword.

In the end, she wasn't sure whether the Knight King had mastered it, but that cheeky brat she had possessed had actually put it into practice without her noticing!

In the end, what on earth was Gaia thinking... to actually agree to let a human use the holy sword.

Meanwhile, not far away, Sajyou Manaka's clear blue eyes shone with unprecedented brilliance as she stared at the young man reflected in the water mirror.

For a long time, Matou Yuu had been like a fairy tale book she had never read before — filled with unknowns and surprises.

But now, the miracles she was seeing in that book far exceeded her imagination.

Holding starlight that symbolized "saving the world"... Wasn't this the "prince on a white horse" she had always dreamed of? The prince who should have only existed in her imagination?

For a moment, Sajyou Manaka's heart was filled with various emotions, and her blue eyes overflowed with unprecedented feeling.

A deeper expectation she had long forgotten resurfaced in her heart once more.

She was looking forward to seeing what kind of surprises this young man would bring her in the future.

Meanwhile, the Beasts present also subtly shifted their gazes while staring at the water mirror.

A look of relief appeared in Tiamat's beautiful eyes. Surprise could not be hidden on Draco's refined face. A deeper meaning was contained within Sesshōin Kiara's captivating and alluring eyes.

"This man actually had a trump card hidden away..."

Kama, hidden in the shadows, inwardly cursed violently while simultaneously feeling an indelible terror at having survived the disaster.

She had originally thought Matou Yuu's greatest trump card was Tiamat, but if she had really thought that, she herself would probably have become the target of that star-shaped Noble Phantasm by now.

Faced with the fully unleashed Star Sword, she — who was already heavily injured — would likely have her spiritual foundation shattered by this single blow.

In contrast to the Beasts who were merely observing the development of the drama, Marisbury's way of thinking had completely transformed.

In the distant ruins, he was still deeply buried in reinforced concrete, feeling an overwhelming metallic taste rising in his throat.

Although he was now a heroic spirit, the residual magical energy emanating from the Star Holy Sword alone was enough to put people on guard.

However... What truly terrified Marisbury was not just that.

...The illusory tentacles of Chaldeas, which had until recently been trying to forcibly analyze Matou Yuu, were now being swallowed by another immense power.

It was... Gaia's "Star Touch."

Whether it was to protect him or simply to prevent other planets from approaching him remained unclear.

"Cough..."

Soon, Marisbury coughed up blood. He could barely move his fingertips. Using both hands to grip the rubble, he staggered out of the deep hole and slowly stood up.

His once-stylish white suit was tattered from the impact, and he looked extremely miserable.

Even the slightest movement sent waves of intense pain he had never experienced before, and it felt as though the bones throughout his body were faintly creaking.

However... That wasn't all.

Because the golden magic on the planet's surface and the tremors on the ground had not yet ended.

The golden magical energy on the planet's surface continued to violently flow into Chaldeas like rivers flowing into the sea... The power of the Star Sword continued to increase at a terrifying exponential rate!

Staring at the golden pillar of light that seemed about to completely pierce through Chaldeas, the former director felt powerless for the first time in his life.

If the terrifying Beasts outside the arena had already made the situation troublesome... then the ultimate trump card Matou Yuu had revealed at this moment was like a depth charge, shattering all of his plans to pieces.

Being able to gather so many Beasts was already impressive, but for a mere human to obtain Gaia's approval and transcend countless laws... Just what on earth was wrong with this man?!

After all, shouldn't such an anti-planetary weapon only be possessed by Grand Saber?!

At this moment, Marisbury's heart sank to rock bottom.

In truth, Gaia's original intention had never been to give the "star-piercing Noble Phantasm" to a human.

However, when this star-forged holy sword was first crafted, the "mold" used was the "prayer of all humanity for tomorrow."

In other words, this sword was a so-called "joint-brand" product funded by Gaia and designed by Alaya.

Its original purpose was to protect Earth from extraterrestrial planets (for example, the white giant star Sefar that descended upon Earth 14,000 years ago). Therefore, when faced with "interstellar threats from outside," Gaia and Alaya's interests aligned perfectly.

In the distant past during the Age of Britain, King Uther and Merlin had mixed the genes of the "Red Dragon of Britain" into Artoria's body at the time of her birth in order to create the perfect king.

In Gaia's eyes, dragons were the pinnacle of the "fantastical species" in this world and the most evolved beings on Gaia's side.

That was why the holy sword had been given to Artoria — but it was not a gift, it was a "loan."

That was why, before the Knight King died, Bedivere had to throw the holy sword back into the lake. The king of humanity had to fulfill his mission and return this celestial weapon to the planet.

To put it bluntly, the final ownership of the holy sword had always belonged in the hands of the planet's will (Gaia).

Now, the Chaldeas movement led by Marisbury posed a serious threat to the planet's survival.

Even if Matou Yuu had said nothing, Gaia would have been desperately trying to shove the sword into his hand and have him swiftly cut down this artificial sphere that was trying to replace it.

Staring at Matou Yuu standing inside Chaldeas, Marisbury continued to steady his breathing. The shock in his eyes gradually turned into coldness.

"It really is unexpected... I never thought Gaia would lend you the sword so easily."

The man's voice crossed the barrier and directly echoed inside Chaldeas.

"But, Matou Yuu... Now that you've stepped into the heart of Chaldeas, can't you understand my noble ideal?"

"I'm doing this for humanity. If we sever our connection to the universe, humanity will no longer need to fear the stars... So why are you trying to stop me?"

Earth was part of the cosmic ecosystem. As long as Earth remained exposed to the cosmic coordinate system, it would inevitably encounter the greed and threats of extraterrestrial lifeforms — such as the wandering star vanguard from 14,000 years ago, the colossal spider living in South America (ORT), and other interstellar predators.

After learning about this matter, Marisbury — the Lord who had studied celestial bodies — had come up with an idea that could only be described as outrageous.

——The Planet Replacement Plan.

If one were to compare the vast universe to a giant "wide-area network," then Earth was like Wi-Fi connected to cosmic signals.

What Marisbury wanted to do was completely cut this "network cable" and replace Earth with Chaldeas to turn it into a "local area network."

This way, Earth would no longer be involved in the workings of the laws of the universe, and disasters from outside would no longer reach Earth. In this "closed planet," humanity would exist eternally and continue to reproduce.

"Since you've told me the benefits, could you please tell me about the costs next?"

Matou Yuu's smile was filled with sarcasm. "What you call 'humanity's survival' is nothing more than building a coffin for humanity to wait for death in... Furthermore, where do you get the right to make the decision to 'become livestock'? Who exactly am I representing?"

Unlike the world Matou Yuu had lived in, within the grand cosmology of the Type-Moon universe, countless alien lifeforms existed, and there were many possibilities that truly existed beyond the sea of stars.

Although it appeared to benefit the general public at first glance, once the veil of good intentions was lifted, Marisbury's so-called "humanity's survival" was actually a terrifying act of mass genocide.

They forcibly initialized the 7 billion survivors on Earth and replaced them with pre-programmed "human clones" brought from Chaldeas, and finally shamelessly declared that it was for the future of humanity...

"Even so, it's still better than aliens exterminating all of humanity in the future!"

Marisbury suddenly raised his face and stared at the young man inside Chaldeas. "Matou Yuu... You can't even imagine how many threats exist in this universe's dark forest, or how many interstellar predators are watching this planet."

"If humanity is to survive eternally, then replacing that fragile old Earth with Chaldeas is the one and only most perfect solution."

Whether Earth should continue to exist in the universe was not something you alone could decide.

Matou Yuu had clearly lost interest in continuing the conversation with Marisbury. He raised the Star Sword in his hand.

A dazzling golden beam of light pierced the sky of Chaldeas. At that moment, the sword gripped in the young man's hand seemed to resonate with the true will of the earth in an unprecedentedly magnificent form.

"Feel the fury of this planet, Marisbury!"

The moment these words were spoken, the sword emitted a clear and resounding sword cry that shook the soul itself.

A terrifying waterfall of light powerful enough to melt everything in the world rained down like a divine command, possessing the power to destroy heaven and earth!

Rumble!!!

The next moment, the false dome inside Chaldeas seemed to split in two, and a bottomless golden rift suddenly opened between heaven and earth!

However, this was not over yet.

Now fully unleashed, the Star Sword was unstoppable and possessed unparalleled absolute violence, as if it were trying to shatter this "fake planet" along with its creator.

Violent spatial tremors occurred throughout Chaldeas, and the colors of heaven and earth changed.

[Warning! Foundational logic has been compromised...]

[Warning! Foundational logic has been compromised...]

[Warning! Warning! Foundational logic has been compromised...]

An ear-splitting alarm echoed throughout Chaldeas and resounded in Marisbury's heart as well.

Through his special power connection with Chaldeas, he watched in terror as the golden world-destroying pillar of light overturned the simulated planet's entire ecosystem with destructive force.

The sky, the earth, the sea... everything was instantly covered by the light of the Star Sword.

However, just as everyone was holding their breath and thinking the Star Sword was about to cut Chaldeas in half——

An extremely strange and suffocating sight unfolded.

The Star Sword, which had been trying to cut Chaldeas in half from the inside, suddenly stopped the moment it touched the "urban center" of this simulated planet.

Then, as if it had touched some kind of taboo, the golden radiance of the sword — which had until then been fierce and unparalleled — began to rapidly weaken at a visible speed and eventually disappeared completely.

"It stopped...?"

Not far from the ruins, Fujimaru Ritsuka blankly stared at the scene reflected in the water mirror with an expression of disbelief. Almost instinctively, she blurted out, "...How can this be happening?!"

Romani Archaman, who had been observing the situation with furrowed brows, seemed to have realized something at that moment.

His pupils contracted sharply, and his voice trembled with disbelief. "Could it be... that the Star Sword's defensive mechanism classified those 'simulated humans' living in Chaldeas as 'human history' that should also be protected?!"

This statement could be described as a warning bell.

Yes, although the Star Sword was a product of the stars, the blade of the Star Holy Sword had originally been modeled after Alaya.

Even before Marisbury deceived the entire world and used Chaldeas to manipulate the Counter Force, Alaya had recognized the simulated humans inside Chaldeas as "friendly forces" that should be protected.

This meant that when the Star Sword confronted this group of fake humans, a critical vulnerability appeared in its defensive mechanism, causing it to lose its own radiance.

"Haa... haa... haa..."

In the ruins of the devastated Crystal Hill Hotel, ragged breathing echoed.

Marisbury's gaze remained fixed on the young man inside Chaldeas. His back was already drenched in cold sweat.

"It really is true... It was only off by a little."

The man's nerves, which had been stretched to their limit, finally began to gradually relax.

He slowly raised his face and stared at Matou Yuu, a pure sense of surprise appearing in his eyes. "If it weren't for 'Alaya,' you might have really succeeded... Matou Yuu."

Meanwhile, Fujimaru Ritsuka and the others — who had initially held a sliver of hope — were now shocked by this sight and wore expressions of disbelief.

"The Star Sword... malfunctioned?!"

Looking at Chaldeas floating in the air, Goetia's face turned pale, and it seemed ready to cough up blood from anger. "The Counter Force is ridiculously troublesome! Especially Alaya on the human side — it's truly idiotic!"

Logically speaking, the fully unleashed Star Sword should have been able to shatter Chaldeas before it was completely "activated."

However, Alaya — the collective unconscious of primates — had judged Chaldeas's fake humans as "human history," thereby weakening the power of the holy sword.

The current situation was extremely awkward.

There was no doubt that the still-unactivated Beast of Analysis, Chaldeas, could not convert the numerous Beasts present into energy.

However, because Chaldeas was a perfect one-to-one replica of Earth, it could not be easily destroyed by external forces.

Seeing this, a faint smile appeared on Marisbury's pale face.

Although he had indeed been surprised by Matou Yuu's actions, the current stalemate was actually more advantageous for him.

It should be understood that Chaldeas perfectly reproduced the ecological laws of Earth, and its "fake human history" would completely "self-repair" over time.

Furthermore, because the flow of time inside Chaldeas was vastly different from the flow of time outside, the longer Matou Yuu stayed inside, the higher the possibility of him being "completely assimilated and dismantled" by the laws of the planet.

Thinking this, Marisbury slowly spread both arms and smiled expressionlessly. "Matou Yuu, you certainly surprised me... However, thinking that a single human's power can stand against the laws of an entire planet is ultimately far too arrogant."

As long as Alaya remained in a state of "deception," the Star Sword would inevitably weaken every time it tried to destroy "human history"... This could be described as an unsolvable dilemma.

Matou Yuu looked down at the Star Holy Sword in his hand. Seeing its light flickering, he remained silent for a moment before quickly raising his face. "Marisbury, I've been holding back until now. If you don't abandon that plan, I'm going to get serious."

Marisbury glanced at the group of Beasts a short distance away and couldn't help but chuckle. "Get serious? Haven't you all been serious enough already?"

This young man had already summoned every Beast he could possibly summon. If Chaldeas hadn't been conceptually equivalent to Earth, he would have been dead long ago.

Matou Yuu took a deep breath as if he had made up his mind and slowly raised his face. "In that case, watch closely."

As he said this, he unconsciously furrowed his brows slightly and casually glanced at Chaldeas — the perfect replica of Earth.

He had thought he understood everything when he unleashed the Star Sword, but now... he was struggling with Alaya's judgment of friend and foe.

As long as Chaldeas continued to be conceptually a planet and was protected by the Counter Force, it was impossible to destroy it through conventional means.

After all, it was a perfect replica of Earth.

Wait a minute...

Looking at this world that was the spitting image of Earth, a blue lightning bolt flashed through Matou Yuu's mind, and his eyes suddenly lit up.

Chaldeas was a one-to-one replica of Earth...?

In other words, conceptually speaking, Chaldeas = Earth?!

An incredibly bold idea suddenly sprouted in Matou Yuu's mind.

If he wanted to destroy the "Earth," then the perfect trump card was hidden inside his own Reality Marble...
