The mental world.
At this moment, it was churning with monstrous waves, stirred by Asuka's furious rage.
The black-haired youth opened his three pupils, his expression grave as he looked at the chaotic mental world filled with lightning and thunder, his brows tightly furrowed.
"The power of wishes is becoming increasingly chaotic... This can't go on..." he murmured.
The giant white wolf, its entire body currently wreathed in gold-red flames, lay at the edge of the void, feeling its master's anger that threatened to tear the entire world apart.
Its blood-red eyes similarly burned with a ferocious light that sought to destroy everything.
Raising its head, it let out a heaven-shaking howl.
Awooo---!!!
Following this howl, the reverse side of the mental world, that boundless Mirror Plain, began to tremble.
The mirror surface shattered.
Countless streams of black mist and malice spread out from within, reaching ferociously toward the sky.
White Shadow sat cross-legged on the ground, playing with Francesca's head in his hands.
His faceless visage coldly watched as those powers were seized by the person on the other side...
"Wow, it turns out your place is quite lively too."
"But you look pretty ruthless, yet it seems you only act tough around me."
To think that even with only a head left, Francesca could still make sarcastic remarks, causing White Shadow to look visibly displeased.
He pinched Francesca's mouth shut and said coldly amidst her wails,
"Shut up, old hag."
Seeing this, Francesca said no more, playfully watching the Mirror Plain shatter inch by inch.
In the physical world.
Sokyoku Hill was trembling.
The gold-red flames on Asuka's body instantly turned into a deep, dark purple!
Those black markings, condensed from malicious intent, spread madly across his entire body as if they had a life of their own.
The markings on his cheeks twisted even further, transforming half of his face into an Asura mask resembling an evil spirit.
The flaming wolf claws on his arms and the giant flaming wolf behind him began to shrink.
Those powers slowly converged onto the long tachi that was beginning to turn purple, forming totem-like patterns and ultimately transforming it into a dark purple, ominous blade.
"Avici---"
Asuka roared, reversing his long tachi so the tip pointed straight at the earth.
Then, using every ounce of his strength, he viciously stabbed it into the scorched earth beneath his feet!
Crack---!!!
The moment the tip of Asuka's blade pierced the ground.
The space around him began to shudder, and rifts appeared out of thin air.
At the same time.
All the Soul Reapers near Sokyoku Hill heard their own Zanpakuto emitting uneasy whispers.
"..."
Although Yoruichi had not brought her Zanpakuto, being sensitive to Reishi, she still felt the malice spreading through the air.
Ichigo Kurosaki furrowed his brows even more tightly.
Because deep within his heart, the black-robed middle-aged man was looking at Asuka with a doubtful gaze.
And issued a warning to him:
"Ichigo, stay away from that man. The thing in his hands is very dangerous."
Meanwhile, at the end of the stairs leading to Sokyoku Hill, Shunsui Kyoraku and Jushiro Ukitake, who had just arrived, also halted their steps.
"Jushiro..." Shunsui Kyoraku's voice carried a hint of dread. "Since when... has there been such an ominous entity in the Seireitei..."
Immediately after.
Reishi ignited, and a destructive shockwave rapidly spread across Sokyoku Hill before collapsing inward, ultimately converging onto Asuka's body.
His lips parted slightly.
An icy voice echoed by the ears of everyone present.
"---Hell of Uninterrupted Agony."
BOOM---!!!
The long blade swung out.
A dark purple wave of Spiritual Pressure instantly erupted.
The ground beneath his feet collapsed and annihilated in an instant, leaving the entirety of Sokyoku Hill teetering on the verge of destruction.
Beneath Asuka's feet, pitch-black gates swung open.
A dark purple pillar of energy, over dozens of meters in diameter, shot up from within!
Like a world-ending geyser erupting from the depths of hell, it tore through the crust and pierced straight through Sokyoku Hill!
With a terrifying might capable of obliterating even space and time, it surged against the heavens!
It viciously bombarded the Garganta in the sky that was just about to close!
"What?!"
Aizen, who had just stepped into the Garganta and believed he had everything under control, suddenly felt a sudden, inexplicable palpitation in his chest.
The Negacion, hailed as an absolute defense capable of isolating all dimensions.
In the face of this hellish light representing ultimate annihilation, it was like fragile glass, emitting continuous sounds of shattering!
He looked down in horror and saw that the dark purple pillar of light had forcibly torn apart the structure of the Negacion, charging straight into the Menos's passageway!
Crack, crack, crack, crack---!!
The passageway of the Garganta began to violently collapse under the impact of this power!
The Gillian-class Menos responsible for projecting the Negacion were caught in the blast of the light pillar; before they could even let out a scream, they were instantly reduced to ash!
"This is impossible! Just what kind of berserk power is this?!"
Kaname Tosen, who had already regrouped with them inside the Garganta, couldn't believe such power existed in this world—power that could actually interfere with another dimension?
The smile on Gin Ichimaru's face could no longer be maintained. He desperately gripped the void beside him, trying to steady his body.
Nichika was so terrified by the horrifying tremors that she fell to the ground.
Looking at the demon-god-like figure below, her eyes were filled with fear.
"So that is Mr. Asuka, the one Father always talked about..."
Above the firmament, the dark purple pillar of light blasted into the Garganta in the final second before it closed!
It violently carved an indelible, scorched scar into the crevice between the two worlds!
What was even more unimaginable to Aizen was that this shockwave, after shattering the Negacion...
Still had enough residual power to come straight for him!
"Bakudo..."
Before he could even finish chanting his Bakudo, the impact of the Hell of Uninterrupted Agony had already arrived right in front of him!
Slash---!!
He didn't know how long it had been since he last experienced pain.
Although it had passed through so many layers of obstruction and the impact had been significantly weakened.
A sharp flash of a blade still slashed across his brow, tearing open a terrifying wound!
Blood gushed from his brow, quickly smearing across half of his cheek.
"...Heh, hahahaha."
Yet Aizen, having been struck by this blade, was not angry. Instead, he revealed an expression of ecstatic joy.
His blood-covered smile was truly chilling to behold...
"That's it... Keep growing at this pace, Number Seventy-Eight."
"Otherwise, without a sense of crisis pushing me, how could I devote myself entirely..."
RUMBLE!!!
Amidst his laughter, the Garganta completely closed, and the remaining impact crashed against the rifts left behind by it.
The aftershocks exploded in the sky, turning into a dark purple meteor shower that rained down upon the devastated Seireitei.
...Everyone fell silent.
Whether it was toward everything that had just happened, or toward this black-haired man who had unleashed this world-shattering strike and still maintained his sword-gripping stance.
His body trembled violently, scalding white smoke billowing out from all over him.
This was Asuka's first time executing this move entirely with his own power.
Compared to that time in Fuyuki City, it was even more berserk and pure.
Similarly, the drain on his Reiryoku was like a tidal wave, nearly emptying him completely.
Asuka raised his head, using those black eyes that had faded from their brilliant gold to coldly gaze at the patch of sky where Aizen had disappeared.
"Run, Aizen..."
"No matter where you run... No matter how high in the heavens you hide..."
"I will definitely find you."
Asuka flourished his blade, and the long tachi subsequently reverted into an Asauchi. At the same time, the remaining hellfire across Sokyoku Hill instantly extinguished.
He casually sheathed Kakudatsu at his waist and whispered coldly,
"...Just wait."
"That day won't be too far off."
