Uehara Shiroha knew with absolute certainty that not every Shinigami's power remained under the control of Squad Zero. There were exceptions to every rule—even rules that governed reality itself.
For example, his Zanpakutō Shunkyō transcended the authority of Hyōsube Ichibē's True Name ability and existed beyond the perception of the legendary Sword God. It operated on principles that defied conventional spiritual paradigms.
Similarly, Kurosaki Ichigo was born possessing fragments of the "Soul King's Body" and therefore had inherent abilities that existed above established rules. This unique heritage allowed him to bypass Squad Zero's regulatory authority and independently condense his Death Hegemony and Zanpakutō without external assistance.
But that kid, Uehara Shiroha reflected, possessed no genuine ambition and consequently squandered this extraordinary talent. In the original timeline, this exceptionally gifted "wild Shinigami" was eventually recruited by Squad Zero and integrated into the hierarchical system of the Soul King Palace—his potential forever constrained by their limitations.
Uehara Shiroha had sworn to himself that he would never repeat such mistakes. His objective was clear: to control the power of authority, not to be controlled by the so-called "320"—a coded reference to Squad Zero. Hyōsube Ichibē should not harbor any delusions about bringing him under control.
He would never join the Soul King Palace. Instead, he would create an entirely new world—one governed by principles of his own design.
In essence, Bankai corresponded to the power of the soul—the complete liberation of one's intrinsic abilities. By contrast, the transcendent power corresponding to the authority of universal principles represented the true power of gods—the evolution of abilities and the quantum leap in existential status.
The former had an upper ceiling corresponding to racial limitations, while the latter genuinely shattered the soul's constraints and opened pathways to an infinite future of development.
Standing in the vast desert of Hueco Mundo, Uehara Shiroha deployed his perfect Observation Haki to capture traces of the realm's fundamental will. The will of Hueco Mundo represented its governing principles—the essential authority and capabilities underlying all Hollows' existence.
With his extraordinarily heightened perception, he seemed to penetrate the veil of reality and glimpse the world's true nature. A primal, ferocious essence permeated the sand sea, jumping forth impatiently like a predatory swordfish breaching the ocean's surface to hunt in unfamiliar territory.
The metaphorical swordfish abandoned its familiar depths to pursue prey. The sharp blade was unsheathed, the tiger released from its cage—both manifestations sharing a singular purpose: to kill.
The primordial will of Hueco Mundo centered on hunting and devouring. Kill, kill, kill! The killing intent erupted outward like a razor-sharp blade severing everything in its path, engulfing the surrounding dimensions.
In that critical moment, the cold moon and endless white sands appeared to become encased in thick, bone-chilling ice. The sky and earth darkened ominously as the sand sea churned with violent intensity.
Within Uehara Shiroha's inner spiritual landscape, a vividly colorful tiger roared skyward, seeking prey to devour. This manifestation embodied the will of Hueco Mundo—a lingering remnant of some ancient, world-destroying Hollow's consciousness that had become woven into the fabric of the realm itself.
Uehara Shiroha responded without hesitation. Gathering his immense Reiatsu and mental fortitude, he exhaled a concentrated breath toward the arrogant tiger that gnashed its teeth with bloodthirsty anticipation.
His golden Reiatsu flowed like living flame, condensing into a lifelike fire dragon with gleaming teeth, sharp claws, and breath of searing flame. The majestic fire dragon entangled the tiger and systematically tore it apart, piece by metaphysical piece.
This confrontation represented far more than mere combat—it was a clash of fundamental wills, a direct confrontation between competing authorities, and a struggle to establish which set of rules would prevail.
The tiger, personifying Hueco Mundo's intrinsic will, burst into spiritual flames and began to burn away under Uehara Shiroha's superior force of will.
Uehara Shiroha spoke with serene confidence:
"Although this is your world, I will control everything now! You can only revolve within my palm! I will dominate all that exists!"
After shattering this specialized manifestation of Hueco Mundo's will with a single concentrated blow, Uehara Shiroha's Reiatsu suddenly emanated blinding radiance. This transcendent light illuminated mind and soul alike, penetrating mountains and rivers with its piercing brilliance.
His sea of consciousness became transparent and luminous. Both his Reiatsu and mental landscape underwent remarkable transformation, gaining new dimensions of power and comprehension.
Through this profound metamorphosis, he officially stepped onto the path of transcendence, beginning his evolution into a god who retained a mortal form—the perfect synthesis of limitations and limitlessness.
What defined true power? Reiatsu constituted power in its raw form. What defined genuine ability? The soul itself represented the foundation of all ability. What defined authentic authority? The power that transcended soul-based abilities manifested as true authority.
This represented the genesis of transcendence. Those who controlled fundamental rules became transcendent beings by definition.
In this pivotal moment, Uehara Shiroha discovered his unique pathway forward and consolidated his personal will into an unbreakable force. Control everything, dominate every aspect of existence—this philosophy formed Uehara Shiroha's distinctive approach to transcendence.
Simultaneously, in a concealed location not far away, Shihōin Yoruichi glanced upward in Uehara Shiroha's direction and raised her eyebrows in acknowledgment:
"You are such a restless, ambitious fellow. I refuse to fall behind you."
She could sense that Uehara Shiroha's strength had increased yet again—a seemingly impossible feat given his already overwhelming power. What a magnificent monster! He had already possessed such incredible strength, yet could become exponentially stronger at any moment, anywhere, without apparent limitation.
This phenomenon left no viable pathway for "ordinary individuals" like themselves to compete. The gap between normal and transcendent had become an unbridgeable chasm.
Shihōin Yoruichi finally comprehended the source of Uehara Shiroha's boundless confidence. For most beings, fear stemmed from confronting unknown, powerful enemies. But for Uehara Shiroha, who commanded truly absolute strength, no unknown threats existed—no rivals appeared within his field of vision.
Invincible power formed the bedrock of his unwavering self-assurance. Now she recognized that she could no longer remain complacent in her current state. If she continued to stagnate, the disparity between herself and Uehara Shiroha would only expand exponentially.
This realization filled her with determination, for she had never been one to accept second place in any contest.
In the distance, both Kuchiki Byakuya and Zaraki Kenpachi simultaneously experienced a fleeting yet unmistakable sense of overwhelming spiritual pressure.
This crushing sensation felt extraordinarily heavy yet oddly familiar. Compared to previous encounters, this spiritual oppression had intensified significantly—directly assaulting their souls, proving nearly impossible to resist, bypassing all defenses, and leaving them momentarily stunned.
The two captains exchanged meaningful glances, both instinctively tightening their grips on their respective Zanpakutō. Their eyes reflected unyielding determination and blazing intensity despite the crushing pressure.
The fighting spirit within their hearts burned with renewed ferocity, their combat instincts heightening in response to this distant challenge. Rather than cowering, their warrior souls responded to this overwhelming power with defiance—their own fighting spirits intensifying in the face of such magnificent strength.
