Uehara Shiroha's observation contained a profound truth. Komamura Sajin, despite his righteous and clear-headed counsel to Tōsen Kaname, would ultimately demonstrate the same psychological blind spot when confronting his own trauma.
In the future Thousand-Year Blood War, when the venerable Captain-Commander would fall in battle, the "most loyal warrior" Komamura Sajin would sacrifice his own heart to activate a forbidden technique—entering a berserk state that granted him temporary invincibility.
For a limited duration, as long as justice burned in his heart, he could resurrect himself infinitely from any wound. But in the end, Komamura Sajin would still perish. Like Tōsen Kaname before him, the wolf-headed captain would ultimately be blinded by hatred, pursuing revenge through self-abandonment.
Idealistic power inevitably requires mental fortitude as its foundation. Once the mind becomes clouded by emotion and faith collapses, even the mightiest techniques become ineffective.
Uehara Shiroha fundamentally rejected this concept of renouncing revenge through self-sacrifice. He recognized that each person's conception of justice differs fundamentally.
For him, revenge itself constituted justice. The true injustice lay in failing to seek retribution when warranted. His philosophy aligned perfectly with his actions—consistent and unwavering.
Unlike Tōsen Kaname and Komamura Sajin, who eventually faltered midway and doubted their own convictions, Uehara Shiroha maintained absolute certainty in his chosen path. This distinction had nothing to do with raw power—these individuals simply lacked the psychological fortitude to carry their convictions through to their ultimate conclusion.
Consequently, they all failed—a simple, inevitable outcome of their internal contradictions.
In the pseudo-Karakura Town, Tōsen Kaname, having exited his Resurrección state, had returned to his normal Shinigami form—though with one significant improvement over his previous condition.
Through the Hollowfication process, his previously non-functional eyes had developed beautiful purple irises. Even after reverting from the transformed state, he retained this newfound vision—a cruel gift that allowed him to witness the world for the first time, only moments before leaving it forever.
Hearing Komamura Sajin's heartfelt words, Tōsen Kaname's newly functional eyes filled with tears. His voice trembled with emotion as he responded:
"Everything appears blurred, yet I can still see. Hisagi asked me to look upon your face one final time. This is truly the last opportunity..."
Observing Tōsen Kaname's expression from his elevated position, Aizen activated a Kidō technique he had previously embedded within his former subordinate. Closing his eyes momentarily, he thought with unexpected solemnity: "Farewell, old friend."
Aizen recognized that Tōsen Kaname had no reason to continue living. Just as Aizen himself would never halt his forward momentum toward transcendence, Tōsen Kaname's journey properly concluded at this precise moment.
Thus, Aizen fulfilled his final promise to his devoted follower.
On the ground below, Tōsen Kaname's body suddenly exploded in a spray of crimson, splattering Hisagi Shūhei's face with blood and viscera. The lieutenant's expression froze in horror as his former mentor disintegrated before his eyes.
Sensing the distinctive Reiatsu fluctuation originating from above, Komamura Sajin glared furiously at Aizen and roared:
"AIZEN! Kokujō Tengen Myō'ō!"
He immediately activated his Bankai once more and launched himself skyward toward Aizen's position, consumed by righteous fury. He could never forgive what Aizen had done—not just to Tōsen, but to countless others caught in his web of manipulation.
Simultaneously, Shinji Hirako and the other Visored surged upward to join the assault. The hatred and resentment they had accumulated throughout a century of exile finally erupted in this moment of collective vengeance.
Driven by grief over his friend's horrific death, Komamura Sajin piloted his enormous "Gundam-like" Bankai toward Aizen with reckless abandon. His Bankai, Kokujō Tengen Myō'ō, manifested as a colossal armored warrior—a titanic samurai that seemed to block out the sun with its immense frame.
This gigantic entity maintained a perfect sympathetic connection with Komamura Sajin, similar to the relationship between a Stand and its user in certain other spiritual systems. The mountain-sized sword clutched in the giant's hand corresponded directly to the Zanpakutō wielded by Komamura.
Critically, this massive warrior was not merely a spiritual projection but possessed a genuine physical form composed of flesh and blood. Any injury sustained by the giant manifested simultaneously on Komamura's body, and vice versa. Should this Bankai suffer damage to vital areas, Komamura would experience identical injuries to his own corresponding organs.
The reverse relationship applied equally—a perfect mirror of consequence.
While Kokujō Tengen Myō'ō possessed devastating offensive capabilities and formidable defensive properties, its weaknesses remained glaringly obvious. Its most critical vulnerability lay in its severely limited mobility—a fatal flaw when confronting agile opponents.
Against an enemy of Aizen's caliber, this "Stand-like Gundam" with its synchronized human-machine connection represented an unfortunate tactical choice. Aizen embodied the pinnacle of combat excellence—the strongest among the strong.
Yet in this moment of blind rage, Komamura Sajin had abandoned strategic consideration entirely. His rational mind overwhelmed by grief, he chose the most direct, aggressive approach regardless of its obvious flaws.
"Aizen, DIE!" Komamura Sajin swung his Zanpakutō at Aizen with unrestrained ferocity:
"You find yourself surrounded with no escape route! I will exact justice for Tōsen!"
As he executed his powerful sword stroke, the towering Tengen Myō'ō mirrored his movement, bringing down its massive blade like a mountain cleaving through space. The devastating slash, infused with potent Reiatsu and fueled by uncontrollable anger, created a terrifying offensive wave that completely enveloped Aizen's position.
With this single strike, the white clouds overhead dispersed instantly, leaving the sky unnaturally clear in its wake.
Confronted by this sky-covering attack, Aizen responded with characteristic calm:
"Your thought process and subsequent actions are fundamentally absurd. Nevertheless, I can comprehend your emotional state. After all, each individual develops their own unique understanding of power."
After this brief philosophical observation, he continued, "True power should manifest like THIS."
In a flash of movement too swift for most eyes to follow, he positioned himself directly before the enormous Tengen Myō'ō and executed a precise sword strike.
A single brilliant flash of his blade effortlessly severed the colossal sword clutched in the giant's hand. Yet his attack continued uninterrupted—the sword's light extending downward to completely sever the armored behemoth's left arm in a clean stroke.
As his Bankai sustained critical damage, Komamura Sajin instantly suffered corresponding injuries. The Zanpakutō in his grip shattered into fragments, while his left arm simultaneously broke with sickening force, spraying blood into the air.
Despite his severely compromised state, Komamura Sajin released a defiant roar, continuing his assault by swinging the broken remnant of his blade with his functioning right arm.
This final, desperate attack—executed at the risk of his remaining life—was casually evaded by Aizen with insulting ease.
