The story begins like.
___________________________
『"When the spiritual world had not yet fully assumed its current form; when Shinigami lacked weapons to call their own, the Menos Grande thrived in Hueco Mundo. During the era of the dawn of Hollows, their evolution was chaotic. They evolved to the Adjuchas level, unable to achieve humanoid forms and lacking willpower, persisting for a long time.
One such ancient spirit, particularly powerful, fought against Baraggan Louisenbairn and others who had reached a new level of evolution: the Vasto Lorde and Arrancar levels.
This Hollow belonged to no group, opposing the hegemony of Baraggan's faction in the sea of Hueco Mundo's sands. A creature endowed with intelligence, it continued to evolve, possessing a torrent of reiryoku. It consumed everything in its path until one day it left Hueco Mundo, spreading its influence to the Living World and the reishi-rich Soul Society, where Shinigami were powerless.
It continued absorbing everything into its body, breaking and destroying everything in its path like a hurricane. A grotesque figure with limitless evolution, it bore some resemblance to the 'Gluttony' ability possessed by the Gillian later known as the Noveno Espada, but that's a different story. Unlike that ability, it couldn't retain the skills of those it consumed but gained a proliferative ability. Instead, the reiatsu of what it consumed accumulated inexhaustibly within its body.
As its reiatsu, compressed within the body of an Adjuchas, grew, it was recognized by Baraggan, who ruled over 'senescence,' as a 'walking disaster of infinite evolution.' The two reached an agreement never to interfere with one another.
One day, after a climactic battle against Shinigami, including the young Yamamoto Shigekuni, it ascended to the heavens to devour the Soul King but was defeated by the Monk and sealed by Nimaiya Ōetsu.
It was given the name 'Ikomikidomoe.'
The Monk used 'Ichimonji' to strip it of its name and rewrite a new one using 'Shin'uchi: Shirafude Ichimonji.' It was then forged into a blade by Ouetsu with its reiatsu sealed as it was.
Its original existence wasn't erased from the cycle of reincarnation, as eradicating the immense number of Hollows condensed within it would have tilted the world's balance.
Until a Shinigami worthy of wielding this power appeared, the blade remained sealed deep within the Phoenix Palace by Ōetsu. A millennium passed in the blink of an eye. The seal was broken, and the blade was entrusted to a new entity. A child without a birthday. In the hands of someone destined to become the King of Souls, this blade was fated to devour him." 』
___________________________________
In the desolate areas of Hueco Mundo, there existed a being that defied all logic known to the creatures of that realm.
"Hollows."
The entity was undoubtedly a powerful Hollow, yet it was distinct in many ways. The creature was larger than usual, even when compared to a Menos Grande, and it had taken the grotesquely beautiful form of an Adjucha, resembling an ōgama.
Unlike humanity, Hollows can grow large enough to pierce the heavens; even when their advantage is derived from equipment or technique, after crossing a threshold not easily overcome, they obstruct the path of progress for the Shinigami. However, the reason this is described as "some sort of advantage" depends on the fact that it is not omnipresent.
It is possible for a Shinigami, who has mastered the Zankensoki to a certain level, to kill even a Hollow ten times their own size. In many cases, Zanpakutōs also have the capacity to rival a Hollow of such enormity. Hollows grow by consuming one another, eventually becoming enormous beings known as "Menos Grande," capable of hindering the Shinigami at every step. Yet from this point, it is common for growth to diverge.
In the process of evolving from Gillian to Adjuchas, and further into Vasto Lorde, the size of a Hollow shrinks, as though the reishi that had expanded their body were gradually being condensed.
But for this Hollow, things were different. Even with its massive size, it was possible to sense among nearby beings the wave of **PRIMAL FEAR** that this entity emanated simply by existing.
However, what was strange was how a being of such magnitude stood still, appearing peaceful—a contradiction to the very nature of Hollows.
Was it calm?
Was it a peaceful being?
A Hollow different from others, seeking something beyond its savage instincts?
No!
Sometimes, a person's wrath becomes so immense that it turns into calmness—and a calm fury is far worse than an explosive one.
A calm fury tends to be more controlled, methodical, and calculated. While explosive anger manifests immediately and visibly, often without much strategy, calm fury is cold and rational, allowing the individual to analyze the situation, plan their actions, and strike with greater precision and effectiveness.
And so—
[That damned god…] A voice that seemed to reverberate from the depths of the earth came from the being that was furiously calm.
It was, in truth, a soul FORCED to reincarnate when a god decided to play games.He was actually a being that was born when the god of Zanpakutō was playing god with a bunch of hollows inside the original holder of this body, and by coincidence, a random soul was chosen to become the new consciousness of this body. One that was from outside this world, but that mattered little to the god in his game.
[If that deity thinks I'll be an obedient dog and stay silent, you're mistaken…] After a moment of silence, Ikomikidomoe muttered to himself before letting out a roar within Hueco Mundo that seemed intent on obliterating everything.
"____________"
His voice shook the atmosphere, transforming its turbulence into wind, and the dense, concentrated reiatsu coalesced to generate numerous aggressive tornadoes in the surrounding space.
A single colossal eye opened at the center of his face. At the same time, a massive amount of reiryoku surged forth from Ikomikidomoe's body. A blinding light engulfed part of the desert. It wasn't a Cero but an explosion of reiryoku radiating outward from himself. The ground ruptured; the quartz sands and boulders were hurled into the air by the sheer force of the blast. The explosion spread so extensively that the increased reiatsu caused it to expand downward into the sands, creating a chasm that descended to the Menos Forest.
...
After the explosion and his subsequent fall, Ikomikidomoe now found himself buried under extensive, deep layers of sand in the ruins beneath Hueco Mundo's desert, within the Menos Forest.
**[How irritating… but much of my rage has subsided.]** The ancient Hollow thought.
**[I'll just sleep and relax… yes… a nap of a few days might help… ZZZZZZZ.]**
…
...…
...

[MEANWHILE]
In the depths of Hueco Mundo, where silence was broken only by the howls of wind passing through the white forest, something had changed. The explosion of reiryoku released by Ikomikidomoe had transformed the environment. It was not merely a kinetic shock; it was a roar that shook the very essence of all beings inhabiting that desolate world.
Above the desert, Adjuchas wandering in search of weaker prey felt the impact. The energy released by the buried giant was not something they could ignore. It was as if a rising sun had appeared on the horizon, its overwhelming presence forcing them to make a choice. Those with intelligence or a sense of self-preservation withdrew, distancing themselves from the epicenter of the power, like prey fleeing an ancient predator. The less rational, driven by hunger or curiosity, cautiously approached the area, like flies drawn to light.
In the Menos Forest below the desert, where massive quartz trees stood like pillars of a shadowy temple, Menos Grande and lesser Hollows also reacted. Some shrank in panic, disappearing among the trees' shadows. Others, consumed by primal instincts, advanced toward the epicenter, hoping to find something to satiate their insatiable hunger.
Yet, others were drawn to the reiryoku released by Ikomikidomoe. Typically, Vasto Lorde remain isolated, but such a raw display of power would attract attention to a potential new predator in this eternal struggle.

"Hmmm… this energy… how many millennia has it been since I last felt it?... Is this a sign of his return? I'll be waiting for you… my old rival…" an ancient Hollow thought, seated on his throne.

'Kukukuku… such immense power~ I'd love to dissect him and uncover all his potential!' a writhing mass of tentacles trembled in euphoric anticipation.

"Such terrifying power… It seems the dark tides of war will once again consume Hueco Mundo…" A dark-skinned Vasto Lorde thought as she gazed at her beloved companions.

"What… is this?... Is it… emptiness? Could it be… empty like me?"
Amid a sea of colorless thorns, a solitary Vasto Lorde wondered, for the first time leaving its cocoon, intrigued by the "emptiness" it had briefly felt expanding.

Within the newly constructed palace of Las Noches, Sōsuke Aizen sat on his throne, exuding an aura of calculated tranquility. Suddenly, a powerful surge of reiryoku disturbed the serenity of his surroundings. Aizen raised an eyebrow slightly—a rare display of interest on his typically composed face.
"Kaname," his voice rang out, soft yet commanding, echoing through the chamber. Tousen Kaname approached and bowed respectfully.
"Yes, Aizen-sama."
"Summon the current Espada for an immediate meeting. It seems we have a new development worthy of our attention."
"As you wish." Kaname responded promptly, vanishing to fulfill the order.
Left alone once more, Aizen allowed himself a moment of contemplation. The emergence of a being capable of releasing such an immense amount of reiryoku was, at the very least, intriguing. In his strategic mind, he considered the implications of this newfound power.
"Interesting…" he mused, a faint smile curving his lips. "If this being possesses potential, it may prove to be a useful piece on the board. Or, at the very least, an element worth monitoring closely."
To Aizen, his associates often resembled pieces in a grand game, each to be maneuvered to achieve his ultimate goals. The possibility of a new player with significant power only made the game more fascinating.
"We'll see where this development leads,"
he reflected, his eyes glinting with curiosity.
As the Espada prepared to convene, Aizen readied himself to make yet another move in his elaborate plans.
