"Boom!"
With a resounding boom, Rozen's body erupted with astonishing magic power that was previously incomparable, surging up like a pillar of fire.
Crimson wings unfolded behind him.
Scarlet eyes appeared in his gaze.
Ten times the magic power at its peak burst from Rozen's body, pushing back the magic storm raised by No. 6, forming a standoff.
And not falling behind in the slightest.
"Su-Such formidable magic power...! How...!?"
Tokoyogi Yuuma was caught off guard by this astonishing magic power, involuntarily taking several steps back, her expression filled with astonishment.
No. 6's pupils also contracted, followed by an exhilarated smile.
"Are you finally taking it seriously?"
Although No. 6 hadn't seen Rozen's power before, she had already imagined that Rozen wouldn't use his true strength when facing her.
Because, with the identical Avrora by her side, Rozen might hesitate to act ruthlessly against someone of his own kind.
Giada seemed to share the same thought, believing that no matter what, Rozen would be considerate of the situation on Itogami Island, restraining his power to avoid causing excessive damage.
Therefore, both of them collaborated with the LCO, needing both a decoy and a reason to force Rozen to take it seriously.
Now, No. 6 finally felt a fatal threat from Rozen.
"This level of magic power is on par with, or even surpasses, that of the Second and Third Generations of vampires."
Even though he didn't know what method Rozen had used to possess such level of magic power as a human, this might also be one of the important factors for Rozen to seal the original and be recognized by his compatriots, right?
No matter what, even if Rozen sealed the original and allied with the Beast Vassals, just having achievements and good conduct wouldn't be enough for them to acknowledge him.
At least, upon hearing from Giada that the power of the Beast Vassals dominated by Rozen had significantly decreased due to insufficient magic power, No. 6 was quite skeptical about how Rozen could gain their recognition under such circumstances.
After all, as the strongest Beast Vassals, subordinates of the strongest vampire, if they knew that being dominated by Rozen would greatly reduce their power, they would never agree to such a thing.
Others might not know, but as an identical existence, No. 6 could be sure that if changing masters would only reduce their power without any other meaning, even if they were sealed together with the original, the Beast Vassals would never recognize Rozen.
Rozen must have been able to gain the recognition of the Beast Vassals because he not only had a way to fully unleash their power but also to surpass it.
No. 6 was certain of this.
Now, No. 6 finally understood why the Beast Vassals would recognize Rozen.
"If such magic power, or even greater power, exists, then our compatriots will naturally be willing to acknowledge it."
No. 6 felt the Beast Vassals in her blood boiling.
In that case...
"Now is the moment when you and I truly decide the outcome!"
Saying so...
"Come forth! The Sixth Beast Vassal——Minelauva Iris!"
No. 6 fully unleashed her Beast Vassal.
Under the burning rainbow flames, the Valkyrie wielding a rainbow-colored sword appeared once again, her size noticeably larger than before, and her power presenting an astonishing surge.
This was No. 6's full power, releasing all of the magic power from the Beast Vassal.
In such a situation...
"Clang..."
No. 6's body began to dissipate like a quickly disappearing Servant, seemingly turning into particles of light.
"No. 6... you...!"
Tokoyogi Yuuma's expression changed instantly.
To this...
"We are the matrix that seals the Fourth Primogenitor's Beast Vassals. Although we can use the power of the Beast Vassals, fundamentally we are still seals. Now, I have completely lifted the seal, allowing the Beast Vassals to unleash all their power. In this situation, my Beast Vassals will be no less powerful than the Fourth Primogenitor himself. All the life force of my body has been transformed into magic power, becoming the power of the Beast Vassals."
No. 6 said indifferently.
"You... you..."
Watching No. 6 like this, Avrora couldn't help but tremble.
"Why? Why would you do this?"
Wasn't she supposed to devour Rozen?
Wasn't she supposed to reclaim their fellow compatriots and become the new Fourth Primogenitor?
What's going on with the current situation?
Avrora was confused.
Such Avrora did not see the last moment, when No. 6 cast a loving gaze at her.
And then...
"Come!"
No. 6 seemed to have shed all emotions, leaving only Rozen in her eyes.
"Let me see if the king who chooses his own fate can bear the power and destiny of us!"
As soon as the words fell, No. 6 drove the Valkyrie, causing her to rush towards Rozen amidst the roaring air burst.
The flapping of her flame wings caused chaos in the entire sanctuary, blowing in all directions like a storm.
Rozen watched as the Valkyrie charged towards him.
"Altera."
Rozen spoke to his servant in front of him.
"Ah."
Attila nodded, without any hesitation, flashing away from Rozen's front.
This meant that in the upcoming battle, Rozen had no intention of letting Altera intervene.
"Since you miss your comrades so much, let's have you meet them!"
Rozen raised his hand, spraying blood mist from it.
"Cone forth! The Second Beast Vassal—Cor Tauri Succinum!"
Rozen finally summoned his Beast Vassal.
Suddenly, endless lava erupted from the ground in front of Rozen, forming a giant bull-headed war god made entirely of lava, wielding a scorching battle axe, appearing in this realm.
"Roar!"
Seeing the female warrior charging towards him, the bull-headed war god roared with joy and determination, as if it had been waiting for this moment.
Originally, with Rozen's magic, even if he summoned his Beast Vassal, its power would decrease to a tactical level. But now, Rozen had used the tenfold amplification of the Crimson Wing Formation, causing the power of these Primogenitor Beast Vassals to swell back to a strategic level, making them no less than the female warrior in size.
Therefore, the bull-headed war god charged forward with its blazing battle axe, facing the female warrior.
"Yes! That's it!"
No. 6 shouted.
"Use our power! Let me see if you have the qualifications to ascend to the peak!"
No. 6's body accelerated its collapse, causing her magic to surge even more terrifyingly.
The next moment, the bull-headed god and the valkyrie met head-on, one wielding a battle axe, the other wielding a greatsword, like gods reincarnated, wielding their weapons against each other.
At the northern end of Itogami Island, on top of a rocky island in the ocean, the dark cathedral suddenly burst into light.
Shockwaves were released from it, shattering walls and collapsing the ground. The entire floating island trembled as if it were on the verge of collapse.
