Bleach: The Invincible Slacker from Rukongai

Before his Zanpakuto had been fused with his being, it had indeed been inconvenient for Aizen to use Kyoka Suigetsu effectively. Because his soul had been unstable and constantly in a state of reorganization.

A continuously changing soul could not immediately adapt to the established power of a Zanpakuto. If the soul underwent too dramatic changes, even the Shikai and Bankai abilities of the Zanpakuto would be fundamentally altered.

Moreover, when reiatsu reached their current transcendent level, the hypnotic ability of Kyoka Suigetsu was no longer completely unsolvable. Just like how even when caught off guard and attacked, Aizen had been able to avoid fatal damage to vital areas.

The abilities of transcendent beings in all aspects had reached previously unimaginable levels of power and perception. And the new Fifth Stage could even surpass typical transcendent limitations to a significant extent.

Therefore, Aizen could now use Kyoka Suigetsu with perfect precision and could even influence those who had achieved transcendent status. Just like Uehara Shiroha's unity of man and blade, as long as an enemy was within the range of his reiatsu, he could affect their perceptions completely.

At the moment when Uehara Shiroha was controlled by Kyoka Suigetsu's complete hypnosis, Aizen had already launched his most devastating killing technique.

He stretched out his pale, bone-like hand and clenched his fist toward Uehara Shiroha's position. In an instant, the purple crystals and Hogyoku embedded in his body shone with blinding brilliance.

At the same time, the massive purple butterfly wings behind him opened wide, revealing countless dark eyes arranged across their surface. Countless blue energy beams shot out from both the purple crystals and the strange eyes adorning the butterfly wings.

For a moment, as if thousands of artillery rounds were being fired simultaneously, the area where Uehara Shiroha was standing became completely enveloped by blue ultra-high-density reiatsu manifestations.

Time and space were sealed, and everything within the target zone faced complete annihilation! The blue reiatsu hurricane tore open black cracks in reality, space collapsed upon itself, and time came to a standstill.

This represented enough concentrated power to destroy entire worlds. Even advanced space-time manipulation techniques could not resist such overwhelming force.

Looking at the collapsing space and time in the distance, Aizen shook his head with satisfaction: "You were certainly strong, I'll acknowledge that much. But you can no longer escape from this attack."

"Today's Ultimate Cero can even destroy the fabric of time and space itself. Even with the assistance of this alternate dimension and your space-time Zanpakuto abilities, you cannot escape!"

"This is my current strength—power that surpasses all previous limitations! Farewell, Uehara Shiroha!"

As soon as he finished delivering this declaration, he felt a sudden chill along his spine and found his entire body being cut cleanly in half. At the same time, Uehara Shiroha, who had appeared to be struggling within the distant explosion, simply vanished.

As Aizen's body began to fall, his regeneration process started immediately, but at a dramatically reduced speed. Because Uehara Shiroha's reiatsu and abilities were far too powerful, they were actively suppressing his complete regeneration capabilities.

Behind Aizen's position, Uehara Shiroha appeared like a deity descending from the heavens. The ice blade in his hand had completely shattered from the effort. Even a perfected White Album could not withstand the combined power of Ultimate Bankai enhanced by the Final Getsuga Tensho.

At the same time, one of the six floating blades behind him was missing, but it was already in the process of reforming and gathering its energy once again.

In this space, Uehara Shiroha could transform into the Final Getsuga Tensho state infinitely and perform ultimate techniques without any limitations or consequences.

From the very beginning of this confrontation, there had never been any realistic chance that Aizen could achieve victory.

Suspended in mid-air, Aizen managed to stabilize his falling body and used the Hogyoku's power to accelerate his recovery process. He looked at Uehara Shiroha, who had suddenly appeared behind him, his face displaying complete shock and disbelief:

"What?! How is this even possible?! What the hell is going on here?"

Now he appeared as if he had seen a supernatural apparition. Was this man somehow immortal?

Obviously, Uehara Shiroha had been controlled by his Kyoka Suigetsu's perfect hypnosis—so why had he suddenly appeared behind Aizen's position unharmed?

With his current enhanced perception abilities, how could such an opponent have approached without detection? And how had his opponent managed to dodge the Ultimate Cero attack without sustaining any injury whatsoever?

The slight aftermath from his attack had spread outward instantly, crossing thousands of miles and completely flattening countless mountain ranges in the distance, leaving behind a bottomless abyss where they had once stood. Yet somehow, Uehara Shiroha had emerged completely unscathed.
