Chapter 644 - 644 Final Fusion State

Aizen's figure flashed, instantly withdrawing his sword and putting distance between himself and Toshiro.

"How interesting. Something I can't understand? I'm afraid? Hmph! Don't talk to me in that tone, as if you're the victor! Just now, your physical strength momentarily exceeded mine! Such miracles happen occasionally! But that doesn't mean your true strength is superior to mine!!!" Aizen said angrily.

Clearly, Aizen, who considered himself a god, could not accept Toshiro talking to him in that 'superior' tone, as if a victor mocking a loser.

"Hmph! Hitsugaya Toshiro, you are indeed a man skilled at creating miracles. But I am an existence that surpasses miracles! So, to prevent another miracle, I will crush you with Kido! I will turn you to dust!!" Aizen shouted, outwardly strong but inwardly fearful.

The change in address, the contradictory words… clearly, although Aizen remained stubborn in his words and refused to admit defeat, after the incident of his powerful strike being blocked one-handed by Toshiro, Aizen's heart was already somewhat panicked. He had lost confidence in close combat with Toshiro.

So, to defeat him, Aizen ultimately decided to use Kido, powered by his own Reiatsu, his strongest suit.

After all, in Aizen's view, Toshiro, who had 'abandoned his Reiatsu' in exchange for powerful physical strength, no matter how strong his body was, without Reiatsu, he would be unable to defend against his attacks, which were powered by Reiatsu surpassing Shinigami and Hollow.

Then Aizen began to chant: "Seeping crest of turbidity. Arrogant vessel of lunacy. Boil forth and deny. Grow numb and flicker. Disrupt sleep. Crawling queen of iron. Eternally self-destructing doll of mud. Unite. Repulse. Fill with soil and know your own powerlessness! Hado #90: Kurohitsugi!!"

As Aizen's voice fell, a black Reiatsu light screen rose around Toshiro, then closed in from all directions like a black coffin, trying to trap him inside.

Aizen shouted with a somewhat frantic expression: "Look! This is the fully incanted Kurohitsugi released by me, who has surpassed Shinigami and Hollow! Under this powerful force, even space-time is distorted. With your level, you cannot possibly understand it! Toshi..."

Bang!

Before Aizen could finish, Toshiro suddenly swung his arm, shattering Aizen's proud Kurohitsugi with a single strike.

The black Reiatsu light screen scattered like shattered glass fragments, and along with it, Aizen's pride shattered as well.

Seeing this scene, Aizen was stunned, looking utterly incredulous.

Kurohitsugi was Aizen's most proficient Kido. Moreover, it was fully incanted and released with Reiatsu surpassing Shinigami and Hollow. It could almost be considered one of Aizen's most powerful attacks at this moment.

But... it was shattered by Toshiro, and shattered as easily as before, with a single swing of his hand.

Toshiro said calmly: "Aizen, you seem not to have noticed. My power far surpasses yours. And... earlier, the one who destroyed a mountain peak with just a swing of his sword wasn't you, but me. So... could you please stop being so narcissistic!"

Whoosh!

As soon as he finished speaking, Toshiro's figure flashed, instantly appearing before Aizen, and slashed at him.

Sclick!

Blood bloomed. Toshiro's Zanpakuto easily cut through Aizen's outer defense. But just as Toshiro was about to further split Aizen in two, Aizen's body promptly turned into countless photons and dissipated before him.

Whoosh!

Countless photons appeared on a small hilltop not far from Toshiro and reassembled into Aizen.

"Ungh..."

Aizen grunted in pain, touching the bleeding wound on his body that Toshiro had inflicted.

The wound was extremely long, from his right shoulder to his left waist, looking quite horrifying. Fortunately, Aizen had turned into photons in time at the last moment, so the wound was not too deep. Otherwise, Aizen would definitely have been split in two.

"You've actively put distance between us? A wise choice. However... this should be the first time in this battle you've actively put distance between us. It seems you clearly understand the gap in our strength," Toshiro said expressionlessly.

Hearing Toshiro's words, Aizen's expression turned cold, clearly furious to the extreme.

"Is that so? It seems blocking my sword has made you quite proud! Destroying my Kido has brought you joy! Injuring my body has excited you! Human!! Stop being so arrogant!!!" Aizen roared like an angry god.

Boom!

A powerful Reiatsu Pillar suddenly erupted from Aizen's body, shooting into the sky. The violent air currents caused Toshiro's clothes to flap loudly. And Aizen's form changed again.

Crimson blood-like tears flowed from the slit resembling an eye on his forehead. His face turned black, and the previous facial skin split down the middle, located on either side of the black face. Three holes appeared on his upper body, with the Hogyoku in the topmost hole. His Zanpakuto fused more completely with his right hand, as if it were naturally part of his body.

Each of the original six giant butterfly wings grew a 'skull' on its ridge. He had no Shinigami characteristics left. At this moment, Aizen resembled a Hollow more than a Shinigami.

"I see... So you won't forgive me either? Hogyoku. To think that I would be surpassed by a mere human. That is indeed an unforgivable thing!" Aizen murmured to himself, looking at his body after evolving again.

Clearly, after being dominated by Toshiro, driven by fear, anger, and the Hogyoku's discontent, Aizen had evolved once more.

"You've become... uglier and uglier, Aizen," Toshiro frowned.

"This is nothing. Didn't I say? Evolution is always accompanied by ugliness. As long as I can obtain powerful strength, these things don't matter at all!" Aizen said indifferently.

Having said that, a 'skull' on one of Aizen's wing ridges condensed an ultra-high-density purple Reiatsu bullet.

"Furetsuha!"

Swoosh!

The ultra-high-density purple Reiatsu Bullet shot rapidly towards Toshiro. Wherever it passed, even space was twisted and shattered.

Seeing this scene, even Toshiro couldn't help but frown slightly. Clearly, even he could not take this attack of Aizen's lightly.

Then Toshiro gently waved his Zanpakuto and chanted softly: "Boseki Senzan!"

Boom! Boom! Boom!

One after another, hundreds-of-meters-high giant icebergs rose from the ground, blocking Toshiro.

Boom!!!

Aizen's Furetsuha ultra-high-density purple Reiatsu bullet slammed into the giant iceberg blocking Toshiro.

For an instant, the entire world fell silent. Then, a mushroom cloud shot into the sky. A spherical, terrifying shockwave spread from the epicenter of the explosion, sweeping in all directions with devastating force.

Mountains, earth, forests, lakes… everything disappeared and was annihilated under the terrifying shockwave of their clash.

Finally, with a crack, the barrier that had been enveloping the entire replica of Karakura Town shattered.
