In that instant, the two fairy-like girls, nearly identical like twins, released astonishingly fierce power.
Their magical energy not only shook the heavens, the earth, and the atmosphere but also made the space itself hum.
They merely unleashed the suppressed power within them, causing the ground beneath their feet to fracture inch by inch, sending debris flying.
The entire world seemed to change color, painted in a dark hue of destruction.
The magical power released by the two girls reached a level comparable to Rozen using the Crimson Wing Formation amplified tenfold.
No, perhaps it was even more than that.
These two vassals, possessing power equivalent to one-sixth of a Fourth Primogenitor, showcased such tremendous pressure.
Shortly after...
"Come forth..."
The second, marked with the Roman numeral 'II,' ordered emotionlessly.
"————Cor Tauri Succinum."
A burst of scorching heat, reminiscent of molten lava, erupted from the second.
The boiling high-temperature from beneath the second's feet turned the ground behind it into lava, simultaneously rising and forming a colossal creature.
It was a bull-headed giant, radiating a glossy amber glow all over its body.
The lava, pouring endlessly from the earth, shaped its body.
Pure and formidable power transformed into a massive, thick battle axe even larger than its body, firmly gripped in its hands.
Standing at a height of over ten meters, this fierce vassal resembled a building.
And then...
"Come forth..."
The No.9, marked with the Roman numeral 'IX,' also spoke expressionlessly.
"————Alnasl Minium."
Instantly, an astonishing storm enveloped No. 9, suddenly appearing.
It was a tremendous storm capable of disturbing the atmosphere, making the space groan.
The turbulent atmosphere roared fiercely, directly transforming into a powerful shockwave. It vibrated violently, expanding like a tornado, revealing a monstrous beast within it.
It was a creature with twisted features, akin to a mirage, exuding a deep crimson hue, adorned with beautiful mane and twin horns.
Its body wasn't lava but shockwaves vibrating at a high frequency.
Its appearance resembled a bicorn, with a body just as large as the bull-headed giant beside it.
This bicorn vassal, no less formidable than the bull-headed giant, levitated, riding the storm.
The legendary twelve Beast Vassals commanded by the Fourth Primogenitor, wielding a power akin to natural disasters, now manifest in this world.
"That is... the Beast Vassals of the Fourth Primogenitor..."
Gazing at the two ferocious Beast Vassals, Veldiana stood there like a puppet devoid of hope, her face pale and expressionless.
"Ugh...!"
Kojou, too, displayed a hint of pain on his face and involuntarily crouched down.
The appearance of the bull-headed giant emitted terrifying high temperatures, turning the earth into molten lava.
The manifestation of the bicorn stirred the atmosphere, creating shockwaves akin to sharp high-pitched tones.
As an ordinary human, being attacked simultaneously by high temperatures and high-frequency sounds would undoubtedly cause intense pain for Kojou.
Even Nagisa, who had been staring blankly at the scene, lost all sense of composure, fixated on the dreadful Beast Vassals.
The only one who remained calm amidst the storm and heat was Rozen.
"Kojou, take Nagisa and that useless young lady and leave."
Rozen, draped in the swirling storm and heat, faced away from the group, staring at the two Beast Vassals before calmly speaking.
"I seem to have no remaining power to protect you all. So, leave quickly to avoid getting caught in the aftermath."
Although, if Rozen unleashed his full power, it seemed these two Beast Vassals could indeed sink the entire Itogami Island. Regardless of where they fled, it appeared there would be no difference.
However, Balthazar Zaharias clearly had no intention of destroying Itogami Island, making it meaningful for Kojou and Nagisa to leave.
Otherwise, in the upcoming battle, Rozen truly had no confidence in winning while having to protect two or three powerless individuals.
The appearance of the two Beast Vassals gave Rozen this feeling.
Rozen was certain.
"That is undoubtedly an opponent more terrifying than dragon kind."
Here, dragon kind did not refer to ordinary dragons like Wyverns but to mythical creatures like the divine beast Fafnir, considered the strongest among Phantasmal Species.
Moreover, each of these Beast Vassals seemed more formidable than Fafnir, compelling Rozen to go all out in battle.
"I wonder how the surrounding area will change with this."
Hence, Rozen had to ensure Kojou led Nagisa away first.
"You guys go find Natsuki-nee. That should keep you safe."
Rozen tossed the Holy Spear to Veldiana.
"Take care of this. Whether you can protect it or not is up to you."
Ignoring Veldiana, who caught the spear in a daze, Rozen extended his hand and snapped his fingers.
"Hum!"
Space immediately rippled, swallowing Kojou, Nagisa, and Veldiana.
"Nichiyo!"
Kojou finally realized and shouted.
"Wait...!"
Veldiana, seemingly regaining awareness, tried to say something but was already engulfed by the rippling space.
"..."
As for Nagisa, she just stared blankly at the manifested Beast Vassals, then turned her head stiffly, gazing at the Holy Spear in Veldiana's hands, her eyes showing a hint of burning flames.
The three of them were directly transported away, disappearing from here.
"Oh my."
Balthazar Zaharias, standing behind the Second and Ninth, expressed interest.
"To actually return the important Holy Spear to that female vampire who has lost her usefulness. Is that a wise decision?"
Balthazar Zaharias chuckled.
To this...
"Anyway, even if you take that thing away, you can't use it. On the contrary, leaving it in my hands might have an impact."
Rozen responded with an unchanged expression.
After some exploration, Rozen had basically understood the nature of that Holy Spear.
"Although it is a Holy Spear capable of slaying Primogenitors, it's not something anyone can use casually. To unleash its power, it requires a large amount of high-purity spiritual energy for driving. Moreover, it can only be effective with the spiritual energy of a Spirit Medium possessing exceptionally special qualities and constitution. Otherwise, it's just something that interferes with magic indiscriminately."
Rozen didn't even glance at Balthazar Zaharias, only staring at No. 2 and No. 9, and the two Beast Vassals they summoned.
"To deal with them, even a slight interference is unacceptable. It's better to just throw it away."
Rozen's words made Balthazar Zaharias burst into laughter.
"A wise decision."
Balthazar Zaharias laughed like this.
But in Rozen's eyes, he had long ceased to exist. He gazed at the calamitous scene before him with a calm smile.
On his body, magical power burned like flames, slowly igniting.
