In the Singularity of Fuyuki City, Rozen, who was still immature and had just begun his first attempt at transferring spiritual particles, had faced the full brunt of the light pillar unleashed by Artoria [Alter]'s holy sword.
That pitch-black torrent of light had brought a true and deadly threat to him.
Had it not been for Mash's class being a Shielder, her defense capabilities being virtually unmatched, that light released by the holy sword could have easily killed Rozen multiple times.
Now, what Rozen was facing was merely the light released from Artoria's fingertips in her divine form, but its power was no weaker than the one he faced back then; in fact, it was even stronger.
Rozen didn't know whether it was the Lion King's divine authority or a Noble Phantasm.
All he knew was that this light, which had turned the land into a tragic sight, would completely annihilate him if he didn't take it seriously.
Therefore, without hesitation, Rozen released his second Beast Vassal.
"Come forth! The first Beast Vassal—Mesarthim Adamas!"
The immaculate divine ram appeared slowly from behind Rozen, its body radiating with the brilliant glow of adamantine jewels, dazzling beyond measure.
"Clang!"
In the brilliance, countless gem-like crystalline barriers appeared in front of Rozen.
These were absolute defenses capable of reflecting any attack.
The light torrent released from Artoria's fingertips slammed into them.
"Booom—!"
The next second, with a sharp tremor, the light rippled across the surface of the massive crystal barriers like waves on a giant mirror.
The light seemed to break apart like a cut wave, scattering countless light droplets.
"—!"
Seeing this, Artoria couldn't help but widen her eyes.
"Did it block my father's divine judgement?"
Mordred, who was stepping on the back of a dragon with her sword impaling its heart, her body drenched in blood, turned her gaze towards the city walls, watching the scene in surprise.
"Did it really block the king's divine judgement?"
Tristan, who was constantly strumming his harp and shooting storm-like arrows that deflected three incoming dragon monsters, also murmured to himself.
"Impossible!"
Agravain, still commanding the Knights, showed a look of disbelief.
"Remarkable."
Gawain spoke in admiration, but his gaze was only briefly cast in this direction before returning to Mash, who was still holding up her shield, panting heavily.
One could imagine how highly the Round Table members regarded Artoria's so-called divine judgement.
Considering the power that could ravage the land in such a manner, they couldn't help but be astonished that a human Master had managed to block it.
However, Rozen's expression darkened.
Because...
"It only blocked it... it didn't reflect it back..."
That was the real surprise.
However...
"If that's all, then you're still far from defeating me."
Rozen sneered.
Blood mist erupted again from his body.
"Come forth! The sixth Beast Vassal—Minelauva Iris!"
The third Beast Vassal was finally unleashed by Rozen.
A Valkyrie with fiery wings appeared amidst the blood mist, wielding a golden greatsword. She swung it down with thunderous force at the light crashing into the gem barriers.
"Clang!"
With a ripping sound, the light was cleaved in two by the golden greatsword, dissipating like torn cloth.
Immediately, the Valkyrie leaped forward, raising her sword high toward Artoria.
"Ching—!"
With a piercing wind-like shriek, a strike capable of cutting through all causality was aimed at Artoria.
As a divine being, Artoria clearly sensed how dangerous this strike was.
Even she knew that if she were struck by it, the outcome would be death, plain and simple.
"Interesting."
Artoria spoke as she slowly removed her lion-like helmet, revealing her exquisite face, shining hair, and star-like eyes to the world.
"A sword that can cut through causality?"
Artoria's voice echoed across the battlefield.
"In that case, let me see if this sword can cut through the causality of the world itself."
As soon as she finished speaking...
"Holy Lance, hoist the anchor."
When those words, almost like a chant, left Artoria's mouth, the world trembled.
"Booom!"
With a hum, a storm began to swirl, gathering in Artoria's hand.
Artoria, as if pulling something out, slowly revealed a weapon before Rozen.
"That is...!?"
Rozen's eyes widened slightly.
"Holy Lance!"
Mordred cried out loudly.
"What?"
Tristan's face, usually solemn, was now serious for the first time.
"She hoisted the anchor..."
Agravain held his breath.
"...."
Gawain also turned his head, looking towards the city walls.
"Senpai...!"
Mash, exhausted and barely standing, could not help but tremble in fear as her body shook.
For in her body, a voice cried out.
It said only one thing.
"———— 'Run away' ————"
A simple sentence sent a chill crawling up Mash's spine.
Even the people within Chaldea shouted in surprise.
"What's with that reading...!?"
Olga Marie exclaimed in disbelief.
"Mana reaction is rising rapidly!"
Da Vinci widened her eyes.
"Rozen...!"
Roman yelled in distress.
Endless light began to converge on the city walls, finally manifesting as a spear.
A spear with a spiral-like shape, resembling a knight's lance, appeared.
As this holy spear was born, Rozen's Mind's Eye clearly sensed the countless ripples running through the world.
It looked as if the very surface of the world had been peeled open.
Now, Rozen understood.
"So that's it..."
This was the true cause of the Singularity's impending collapse.
This was the real reason why King Arthur had transformed into the Lion King.
Everything was because of it.
Because of that holy spear.
Its name was...
"————Rhongomyniad."
Rozen spoke the name aloud.
And then...
"Disappear."
Artoria declared quietly.
"The Lance That Shines to the End of the World ⟨Rhongomyniad⟩."
Artoria unleashed the true name of the Holy Lance.
Immediately, the endless light gathered and flickered, transforming into a world-shaking beam of light. With a thrust of Artoria's holy spear, it shot out like an avalanche of light, roaring forth.
This beam of light tore apart the Valkyrie, shattered Mesarthim Adamas, broke through the gem barrier, and swallowed Rozen's figure.
"Senpai!!!"
Mash's anguished cry echoed across the battlefield, lasting long into the distance.
