The Netherworld—
Rather than dim, it would be more accurate to say the sky was shrouded in a layer of pale purple light.
The sky and the earth, everything seemed turbid, devoid of any trace of human presence.
This was the depths of the Netherworld, a forgotten place.
There, Rias found the Beast Emperor sealed by the God of the Bible.
It had seven heads and ten horns, with seven crowns upon its seven heads.
Hundreds of meters in total length, its body was covered in black fur, with hardened, scale-like parts visible everywhere. Those scale-like parts were as red as fresh blood. Red protrusions—shaped like horns—sprouted all over its body.
The seven tails growing from its haunches were all thick and long, each with a completely different shape.
There was a lion's tail, a dragon's tail, and features of various other beasts.
"No matter how many times I look at it, this thing is truly ugly."
Rias gazed at the Beast Emperor and couldn't help but sigh.
Upon the slumbering Beast Emperor, various lights flickered—those were seals.
The seals placed upon Beast Emperor 666 were extremely complex, numbering over two thousand in total, each possessing various effects.
Just looking at them was enough to make one's scalp tingle. High-level Magic Formulas were combined and mixed with rituals and the like, all working together to suppress this being of Sub-Dragon God Level.
The reason Beast Emperor 666 was a Sub-Dragon God was its lack of reason, preventing it from utilizing its vast Power.
Its attributes were infinitely close to a true Dragon God, but its offensive capabilities were slightly inferior. Only its recovery ability was exceptionally strong.
That immortality was such that even the God of the Bible could only seal it, with no means to kill it.
What the God of the Bible could not do, Rias could. Even a Dragon God of the same level could be slain by her.
This was a difference in essence.
Although their forms of life were of the same rank, their levels of Power were different.
"Hakai Hōteishiki Nine: Destruction's True Form!"
BOOM!!
A terrifying roar erupted, and the purple light of the entire Netherworld was tainted, turning red.
A crimson light spread from Rias as the center. In an instant, Rias's body transformed into a red silhouette.
Hakai Hōteishiki Nine—this was a transformation of life form.
It converted the mortal flesh body into an energy form, thereby maximizing the manifestation of its destructive nature.
Altering her own life form, this move was one of Rias's trump cards for challenging opponents above her level.
In just a moment, the seals laid by the God of the Bible were utterly destroyed.
"Be destroyed!"
A cold, heavy voice resonated. The crimson light transformed into a pillar of light connecting heaven and earth.
A colossal pillar of light, hundreds of meters in radius, shot into the sky. Under Rias's attack, Beast Emperor 666 turned to ashes.
A total of seven lights flickered, stubbornly persisting within Rias's crimson Power of Destruction.
These seven were precisely the cores of Beast Emperor 666.
Unlike other Dragon Gods, the core of Beast Emperor 666 could split, dividing into seven.
"Still regenerating, huh."
Rias gazed indifferently at the seven lights before her and couldn't help but whisper softly.
And at this moment, Rias took no action.
She merely existed here.
That's right. Just by existing here, she destroyed everything.
If Sirzechs's Devils True Form was equivalent to the will of Power of Destruction, then Rias was Destruction itself.
Possessing the 'complete' concept of destruction, and having condensed it into a Power.
Although incomplete, merely at the level of a fragment, this already surpassed this world!
"Tsk, this immortality... truly worthy of Beast Emperor 666. Only its recovery ability deserves praise."
Rias murmured softly.
By now, the Netherworld had begun to tremble. If this continued, the Netherworld would likely be destroyed.
Including Rias further elevating her essence of destruction, the same would occur.
Before Beast Emperor 666 died, the Netherworld might collapse.
The resulting consequences might not be much less severe than Beast Emperor 666's emergence.
This had nothing to do with whether Rias tried hard to control herself, because her very existence in this form placed a severe burden on the world, leading to its collapse.
However, it wasn't entirely without a solution.
"Shall we play a game?"
As if faintly hearing the lament of Beast Emperor 666, the corners of Rias's mouth slowly curved upward.
"Hakai Hōteishiki Eight: Domain of Destruction."
In an instant, the world transformed.
The originally invaded purple completely turned crimson-red. Within this domain, no existence other than Rias could remain unaffected.
Rather than a Domain of Destruction, it was more like a World of Destruction.
In that fleeting moment, Rias brought the concepts of 'destruction' and 'create' to their extremes, then constructed this small world.
Complete concepts, complete laws, complete rules—
Simply by drawing it into this world, Beast Emperor 666 was annihilated.
"That really took some effort~"
Rias chuckled lightly and returned to her original form.
After the seven cores were completely annihilated, the concepts within them were rejected by the entire world and then condensed into substance.
Rias 'looked' at the concept in her hand and began to analyze it.
Beast Emperor 666 is recorded in the Bible, which also means that within the world, Beast Emperor 666 has been integrated into the Biblical Pantheon.
Therefore, Beast Emperor 666 possesses multiple concepts.
The most complete among them is the concept of Dragon!
That's right. Although Beast Emperor 666 resembles a chimera, possessing features of various animals and representing chaos itself...
In truth, He is a Dragon.
In the Bible, He is called the incarnation of Satan and is also referred to as the 'Great Red Dragon.'
Like the fiercest weapon, He represents The End.
Known as the ultimate monster that, once awakened, would destroy the world.
Great Red (Great Red), symbolizing the limit, i.e., 999, presiding over 'dream.'
Ophis, symbolizing infinity, i.e., 888, presiding over 'Infinity.'
God of the Bible, symbolizing Omnipotence, i.e., 777, presiding over 'Omnipotence.'
Beast Emperor 666, symbolizing calamity, i.e., 666, presiding over 'The End.'
"I feel like something is still missing."
Rias looked at the concept before her and couldn't help but ponder slightly.
Although she wanted to begin create, she suddenly felt like adding something to it.
"Ah, right, outside the system..."
Suddenly, Rias was taken aback.
Although Beast Emperor 666 has been integrated into the Biblical system, because it was sealed and inactive, it was only slightly revealed in the Apocalypse.
Additionally, Beast Emperor 666 was not originally a product of the Biblical worldview in the true sense but was integrated into the Biblical system, so there's a slight issue in this regard.
"Mythological concepts are conflated. Beast Emperor 666 is conflated with Satan, Lucifer, and Samael, but because it is an independent 'Dragon,' it might be unable to bear the position of the Evil Tree."
"Then... next, merging the concepts of Samael and Beast Emperor 666 might create something interesting~"
Rias suddenly thought of a great idea~
