This was an absolute elemental advantage.
Asuka's Bankai was simply the natural enemy born to destroy this kind of existence.
Gouka Kourou was an interrogator from hell, naturally far more terrifying than any evil demon.
Currently, Asuka had developed two abilities for his Bankai.
Gathering the malice and pain he received into pure negative energy, he merged it with Nugata's Reiryoku.
And upon reaching the critical point, he would release it all...
This was [Avici・Black Rope Hell].
Legend had it that in that endless hell...
The jailers of Yama would bring the hellish beings, who looked like charred firewood, to the scorching iron ground, using black lines to divide their bodies into four, eight, sixteen, thirty-two parts...
Then, they would cut them with red-hot iron saws.
The newly sawed parts would immediately stick back together, requiring the jailers to divide them again, making them repeatedly experience the agony of being sliced apart.
And the black lines Asuka slashed out were exactly like the ropes of hell.
The other was [Avici・Scorching Hell].
Gouka Kourou would release the blazing karmic flames of hell to roast the soul and essence of the one being judged.
If it were a kind person with a pure heart, the effects of the Scorching Hell might actually be underwhelming.
After all, this was a special ability that struck directly at the heart; the more sinful and malice-ridden a person was, the heavier the pain they would suffer.
At that time, scorched flesh, bitter agony, and the convergence of a myriad of poisons would be trivial matters.
If one died under this fire, their entire soul would eternally fall into the Avici hell, never to be reincarnated.
And this, when facing Metastacia, who had embraced All the World's Evils...
...was a lethal poison.
Metastacia struggled in the raging flames, feeling his control over Gilgamesh's body rapidly slipping away.
That arrogant will belonging to the oldest king was furiously battering against his suppression like an awakening dragon.
Metastacia had gone completely mad.
He no longer tried to suppress Gilgamesh, but forcibly drew upon all the Magical Energy in the body, even beginning to burn Gilgamesh's Saint Graph.
He wanted to trigger a mutual-destruction magical explosion! To turn the entire Mount Enzou to ash!
The surrounding space began to vibrate violently, countless black cracks spreading through the air.
The Gate of Babylon completely lost control, thousands of Noble Phantasms firing indiscriminately in all directions, blasting the entire Ryuudou Temple full of holes.
"You want to take us both down? Did you ask me first?"
Asuka's gaze sharpened, and he violently thrust the long tachi in his hand into the ground beneath his feet.
"Heart Mirror—"
Hum—!!!
With this as the center, a golden-red halo instantly expanded outward.
In the blink of an eye, it formed a massive hundred-meter hemispherical domain, enveloping Asuka and the rampaging Gilgamesh within.
The inner walls of the domain were not solid, but a flowing, mirror-smooth golden-red curtain of light.
Within this domain, time seemed to flow much slower.
The originally chaotic and violent magical turbulence became clearly visible in this space.
All the malice, killing intent, pain, anger...
Every negative emotion was captured by this massive Heart Mirror, then unreservedly dismantled and fed back into Asuka's mind.
At this very moment, in his field of vision...
Gilgamesh's body was no longer flesh and blood, but a massive amalgamation of energy.
He clearly saw how that white bone mask had taken root on the Spirit Core like tree roots, saw how those scarlet tentacles were wrapping around the golden Divinity, and even saw...
...at the very center of that chaotic energy, the weakest connection point!
"I see it."
Asuka pulled his sword from the ground, his figure vanishing from the spot.
Metastacia, whose self-destruction was forcibly suppressed, tried to fight back, only to find he didn't know where to strike.
He realized in horror that no matter how he manipulated the Noble Phantasms to defend, that black Soul Reaper could always slip through the gaps in the airtight barrage like a gust of wind.
Fast! Too fast!
Under the enhancement of the Heart Mirror domain, Asuka's speed reached an unimaginable level, and his trajectory was completely unpredictable.
Because in this domain, the enemy's every move, even the flow of Magical Energy in the next instant, was already reflected in advance by the mirror!
"It's over, parasite."
A cold voice rang out right in front of him.
By the time Metastacia reacted, Asuka had already appeared before him, the distance between them less than half a meter.
The black blade infinitely magnified in his pupils.
It was as if he had actively thrown his own body onto the opponent's blade!
Squelch—!!!
The long tachi had no flashy movements; carrying an indomitable momentum, it accurately pierced right between the brows of that white bone mask!
Then, following the momentum, it slashed upward!
"Get the hell out—of this world!!"
Asuka roared, gripping the sword with both hands, using all his strength to execute the upward slash.
[----!!!]
Accompanied by a shrill scream, the bone mask parasitizing Gilgamesh's chest and face, along with the large mass of disgusting rotting flesh attached behind it, was forcefully ripped out of Gilgamesh's spiritual body!
Thud.
A writhing, foul-smelling lump of flesh fell to the ground, still desperately trying to crawl toward Gilgamesh's feet.
Boom!!!
The next second, a golden battle boot viciously stomped down onto that lump of flesh.
Massive golden Magical Energy erupted like a volcano, surging from the figure that had stood up straight once more.
Gilgamesh slowly opened his eyes.
Those eyes, originally covered in black, had now returned to their blood-like crimson.
That was the enraged red belonging to the oldest king.
"Mongrel—!!!"
Gilgamesh's voice was terrifyingly deep, as if coming from the deepest hell, every word like a steel nail spat out after chewing through iron.
He looked down at the writhing filth beneath his foot, his facial expression twisted to the extreme.
As the king who stood supreme above all in heaven and earth, to actually be parasitized by such a lowly reptile, and even manipulated into doing such ugly...
This was a humiliating disgrace worse than death!
"How dare you... how dare you treat my divine body as your nest..."
"How dare you touch my soul with your filthy tentacles..."
Gilgamesh raised his hand. The space behind him violently trembled, and dozens of golden scepters symbolizing royal authority appeared behind him.
"Be reduced to ashes!!"
Boom boom boom boom boom—!!!
Dozens of high-density Magical Energy beams bombarded Metastacia's remnants at point-blank range, blasting him to pieces.
Even the dregs of his soul were ruthlessly smashed into the ground by this enraged Magical Energy.
Yet even so, through the existence of the Heart Mirror, Asuka still caught a faint trace of evil aura.
Metastacia's remnant soul, already blasted into a Reishi state, was still trying to cling to life, looking for a chance to escape back to the Great Cavern.
But unfortunately, Asuka had already found him.
