There was no denying that Iblisveil Aziz, after devouring a second-generation noble, had become truly terrifying. The waves of magical energy emanating from him spread like black mist, causing the ground to tremble faintly across the area.
The scorched wasteland left behind by Regulus Aurum seemed to shudder in fear, the earth cracking as countless pebbles rattled—as if an earthquake were imminent, forcing everyone to hold their breaths.
Yukina was no exception.
Tobias and Kira wore equally grave expressions.
Only Vatler remained silent, watching with an amused smile.
Rozen, however, faced the direct descendant of the Second Primogenitor with utter calm.
Then—
"Come forth—Duamutef!"
Without any warning, Iblisveil unleashed his magical energy, transforming it into a blood mist that coalesced into a Beast Vassal.
It was the same massive golden jackal from before.
The golden jackal let out a fearsome roar, turning into a streak of light as it charged toward Rozen.
"Senpai!"
In a situation where no one had expected Iblisveil to attack so suddenly, only Yukina—with her Spirit Vision—had sensed it coming, crying out in alarm.
But Rozen remained unfazed.
From his body erupted a surge of magical energy no less overwhelming than Iblisveil's—no, even surpassing it.
"Come forth."
Rozen's voice was ice-cold.
"Regulus Aurum."
With that simple declaration, blood mist burst from his magical energy.
The mist transformed into lightning.
The lightning took the form of a colossal lion.
The thunderous lion, wreathed in countless bolts of lightning, roared like a peal of thunder before charging forward as a streak of lightning, crashing into the oncoming golden jackal.
"BOOM!!!"
A deafening explosion resounded the next second.
Amid the scorched wasteland, endless lightning erupted once more.
This time, however, the lightning clashed against the golden radiance—like spear meeting shield—neither yielding, resulting in a violent collision.
The impact caused catastrophic destruction, shattering the earth, unleashing storms, whipping up dust, and fracturing the bedrock—an utterly terrifying sight.
But the outcome was decided quickly.
The lightning overwhelmed the golden light, forcing the golden jackal to let out a pained howl before being vaporized by countless bolts of lightning, vanishing without a trace.
"What?!"
Iblisveil's expression stiffened.
There was no helping it.
The power of the Beast Vassal Rozen had summoned far surpassed that of the Fourth Primogenitor's Matrices he had faced during the Blazing Banquet.
Even if the Fourth Primogenitor itself had descended and summoned its Beast Vassals in person, the result might not have been any different.
Yet Rozen was wielding a Beast Vassal that wasn't even his own, unleashing power comparable to its original master—and even seemed to be holding back. This realization sent a shock through Iblisveil's heart.
But it only ignited the prince's fighting spirit further.
"Crush him—Qebehsenuef!"
Iblisveil summoned his second Beast Vassal, his magical mist taking the form of a bird of prey.
It was a golden falcon with wings spanning fourteen to fifteen meters, each flap unleashing countless rotating wind blades.
The golden falcon let out a piercing cry, its massive wings sweeping forward, transforming the wind blades into a storm that kicked up dust and shook the atmosphere, instantly creating a typhoon of hurricane force that darkened the heavens.
In response—
"Alnasl Minium."
Rozen summoned his second Beast Vassal as well.
A crimson-maned, twin-horned warhorse emerged, also wielding the power of storms.
Its body vibrated intensely, capable of inducing resonance through high-frequency oscillations to destroy all matter—while simultaneously controlling wind and atmosphere. The Beast Vassal let out a fierce cry.
Between its savage horns, a storm formed by high-frequency vibrations surged forth like a tornado, colliding head-on with the incoming typhoon in a deafening explosion.
The two storms clashed, the surrounding earth crumbling and shattering into countless fragments, swept up into the whirlwind and scattered wildly.
It was a scene straight out of the apocalypse.
Yet, once again, Rozen emerged victorious.
The twin-horned warhorse's storm overpowered the golden falcon's, surging toward Iblisveil's position.
The prince's golden eyes finally turned crimson.
"You too—Hapy!"
Iblisveil summoned his third and final known Beast Vassal.
It was a massive, golden-furred baboon, its muscles bulging grotesquely.
The golden ape let out a terrifying roar before leaping through the storm, throwing a punch toward Rozen with enough force to crush the very atmosphere.
That single strike could have obliterated a mountain—its power was peerless.
Yet, Rozen still showed not a hint of fear.
"Cor Tauri Succinum."
With a calm invocation, a molten giant wielding a blazing battle-axe materialized.
The bull-headed titan stood before Rozen, its eyes gleaming with ferocity as it watched the golden ape's devastating punch descend.
Then—with a mighty swing—it brought its axe down in a strike so intense it vaporized the surrounding air and incinerated the storm itself.
"Boom!"
The terrifying fist descending from the heavens clashed with the devastating axe rising from below in an earth-shattering explosion.
The shockwave became a second storm, shaking the wasteland to its core—already on the verge of collapse—before finally causing it to cave in, crushed into oblivion.
It was a sight worthy of a natural disaster.
Like watching an entire continent being torn apart, destroyed, and reduced to rubble before one's very eyes—utterly horrifying.
Even more horrifying was the fact that, within this apocalyptic scene of destruction, everyone could clearly see the molten bull-headed titan cleaving the golden ape in half, reducing it to nothingness.
Two individuals. Six Beast Vassals.
In the end, Rozen emerged victorious across the board.
Before long, the thunderous lion, the twin-horned warhorse, and the bull-headed titan vanished into blood mist with triumphant roars, leaving no trace behind.
Only Rozen and Iblisveil remained, standing in the shattered ruins of the battlefield, staring at each other.
Their expressions were starkly different.
Rozen wore a faint smirk, utterly at ease.
Iblisveil, however, was grim-faced and silent.
Then—
"If this was just a test, I'd say it's gone far enough, wouldn't you, Prince Aziz?"
Rozen spoke casually, as if it were nothing.
Yes.
That terrifying clash had merely been a test.
That was why Rozen hadn't gone all out.
But Iblisveil's expression darkened.
Because while the first half might have been a probe, by the end, he had already fought with everything he had—and still been completely overwhelmed.
"So the rumors about the Third Primogenitor's defeat at the hands of a mere human… weren't just baseless nonsense after all."
Iblisveil had confirmed it beyond doubt.
