"Boom!"
Another surge of pitch-black flood came crashing, slamming against the barrier of radiance, and the roar this time was far louder than before.
But this time, the barrier of radiance had turned into a dome of light, enveloping Rozen. As Rozen shot skyward, it bore the brunt of the black torrent, parting it like cleaving through a black sea, while carrying him straight up to the heavens—toward Tiamat above.
"Aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa————!!"
Tiamat's gaze locked tightly onto Rozen, releasing a furious, ear-splitting cry.
"Haa..."
Rozen inhaled deeply, then exhaled.
All of a sudden, a terrifying and resplendent aura of mana erupted violently from his body.
Endless High-Grade Mana surged forth from Rozen, causing the brilliance of his Magic Crest on his right arm to shine like a starry sky, dazzling to the extreme.
In the next moment, a blaze of golden flames erupted from Rozen's body.
"Burn!"
Rozen invoked the power of Cleansing, summoning the Flame of Fudo Myoo.
The flame capable of reducing the Three Thousand Worlds to ashes and incinerating endless demon armies—this had always been Rozen's most favored jujutsu in the past.
But this time, what he summoned was not merely a spell like Fire Realm Incantation, but the genuine authority of Fudo Myoo—the true flame that could indeed consume the Three Thousand Worlds.
By compressing High-Grade Mana to the extreme and wielding it through the power of Cleansing, Rozen could now grasp the very authority of the gods.
However, this alone was not enough.
"Blessing—Destruction!"
To inflict real damage upon Tiamat, Rozen used Cleansing to mimic the power of Destruction, granting its attribute to the divine flame.
Immediately, the flame that had once shone as brilliantly as the sun twisted, turning into an abyssal black, becoming a true demonic flame. It erupted from Rozen like a volcanic explosion, growing ever larger.
Before long, the entire sky was consumed by the black inferno, transforming into a heaven of fire.
"Aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa————!!"
Witnessing this, Tiamat cried out again, as if sensing mortal threat. Around her surged an endless black sea, spreading to engulf the entire land.
In that instant, heaven and earth were divided between man and god—one turning the sky into a blazing sea of fire, the other turning the ground into a black ocean. One commanded the fire of the gods, the other the mud of the gods. Truly, they had become as irreconcilable as water and fire.
Then, without hesitation, both sides unleashed their attack upon the other.
"Haahhhhhhhh!"
Rozen shouted loudly, spreading his arms wide. From the fire-sea above, countless meteors of black flame plummeted down like colossal obsidian asteroids, crashing toward Tiamat.
"Aaaaaaaahhh!"
Tiamat roared back defiantly. From the black sea around her, countless dark waterspouts rose like colossal dragons, spiraling upward toward the heavens.
Thus did man and god launch merciless assaults upon one another.
"Boom!" "Boom!" "Boom!" "Boom!" "Boom!" "Boom!" "Boom!" "Boom!" "Boom!" "Boom!"
Soon, the world resounded with thunderous detonations.
It was the sound of black flame meteors clashing relentlessly with the black sea.
As the massive chunks of obsidian-like flame fell upon Tiamat, the waterspouts surged forth like countless black dragons, shaking the skies as they twisted and coiled, intercepting the meteors in midair, colliding ceaselessly with earth-shattering force.
In this battlefield, water and fire both seemed to come alive, roaring and raging without end, each side hurling destruction at the other.
At the same time, Rozen and Tiamat had already begun their direct clash.
"Aaaaaaaaahhh!"
Tiamat swung her massive claws at Rozen, tearing through the air like a storm, striking down upon him.
"Bang bang bang bang bang...!"
But Rozen's figure blurred, vanishing as if by teleportation, reappearing at another angle in the next instant. His hands flared as he unleashed waves of black flame upon Tiamat, pounding her body with explosions like endless bombardments.
Tiamat howled in pain, enraged beyond measure. She unfurled the conceptual domain of Anti-Genesis, attempting to dye all around into nothingness, replacing the very world itself.
Within that Nega-Genesis conceptual domain, both the black sea and the infernal flame alike were erased, vanishing utterly.
That reality-altering domain forcibly reshaped the ecosystem of the world, annihilating everything save for the living, reducing it all to void.
However—
"Altering the world's surface? Who wouldn't be able to do that?"
Rozen raised his right hand high, the glow of his Magic Crest shining even brighter. Countless radiant particles scattered into the air, crushing everything around like a conceptual domain of his own.
Caught in its sweep, many Laḫmu were instantly reduced to ash, vanishing completely. Even swathes of the black sea were devoured outright, erased in full. And even Tiamat's expanding conceptual domain was blocked, pushed back by the flood of radiant particles.
"Non-living things cannot approach?"
Hovering in midair, Rozen looked down at Tiamat.
"Then let me, a living being, overwhelm you!"
Saying so, Rozen recalled both the black feathered mantle and the ornate ring on his finger, dissolving them into light particles and merging them into his body.
There was no other way. Within the world of Nega-Genesis, divine tools forged from gods like Kinu and Gyokuto would instantly be annihilated upon entry.
"Shhhk!"
So Rozen recalled both deities, and instead gripped a flame of light. From it emerged the Sun's Holy Sword. He raised it high, and in a sudden burst of speed, shot forward, appearing right before Tiamat in an instant.
"Splurt!"
Before she could even react, Tiamat's face was cut across by Galatine, wreathed in destructive energy, leaving a deep wound upon her cheek.
"Aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa————!!"
Tiamat shrieked in agony.
"Clang!"
But Rozen did not relent. He invoked the sword technique of Twin-Wings, his figure flashing ceaselessly around Tiamat's massive form, striking without mercy. With Galatine imbued with Destruction, he carved into her draconic body again and again.
In moments, Tiamat's form was covered in wounds.
From above, the fire-sea rained down meteors of infernal flame, hammering her body with more explosions, wringing yet another scream from her.
Back in Chaldea, the reports rang out once more.
"Beast II's Saint Graph readings dropping again!"
"Saint Graph structure compromised! 99%... 98%... 97%... still falling!"
"D-Don't lose, Rozen!"
Roman, Da Vinci, and Olga Marie all shouted desperately.
This time, Rozen had chosen the most direct method—challenging Tiamat head-on, weakening her Saint Graph with brute force.
"Aaaaaaaaaaaaa————!!"
Tiamat raged, churning the black sea, trying once more to use the mud to restore her Saint Graph.
But Rozen would not allow it.
"If this black sea can restore your Saint Graph, then I'll burn it away completely!"
He raised his hand high.
"Fall!"
At his command, the sky—entirely engulfed in the black fire-sea—trembled with a deafening roar as it descended.
"Ruuummmmble————!!"
In an instant, the infernal sea of flame crashed down upon the black sea, producing an explosion louder than any before.
The black sea was relentlessly seared by the descending blaze, steadily consumed until nothing remained.
