Crossover Anime: Starting with Bankai from Demon Slayer

Chapter 309 Enemies meeting are filled with intense hatred

"die-!!!"

The only response to Aizen's joy was the burning blade.

Although Asuka had imagined countless times the scene of her reunion with Aizen.

After experiencing so much, I thought my mindset had changed a lot.

But when he actually saw the gaze that had haunted his midnight nightmares, he was still completely unable to suppress the anger in his heart, and his body began to tremble with excitement.

He didn't want to hear Aizen say another word, and swung his sword to strike!

His face was covered with markings that seemed to gather evil thoughts, which provided him with a burning power like kindling.

This strike was filled with his purest killing intent!

boom!!!

The ground shattered, and the air exploded.

He gathered all his spiritual pressure into a single point and unleashed it at such a speed that even the combatants, Gin Ichimaru and Byakuya Kuchiki, couldn't see him clearly.

In the blink of an eye, his bloodshot eyes appeared before Aizen.

The mongoose let out a furious sword cry, its blade igniting the air as it slashed fiercely down at Aizen!

Faced with such an attack, Aizen did not retreat.

His smile remained unchanged as he calmly raised his left hand, without even using his Zanpakuto.

In his view, although Number 78 is special, the upper limit of his spiritual pressure is still locked by the limits of the Shinigami.

In addition, he had once possessed some of Asuka's memories from the Taisho era and had witnessed his state of spiritual pressure rampage in the present world...

At best, he's only at the captain level.

"What a warm greeting, Asuka." Aizen, who had already dropped his pretense, became gentle towards Asuka: "However, with this much power, it's insufficient..."

clang-!!!

The deafening impact resounded through the sky.

Aizen's pupils contracted sharply the moment they touched the blade.

It wasn't as easy and effortless as I had imagined.

When Asuka's attack struck Aizen's hand, which was covered in immense spiritual pressure.

That terrifying force caused Aizen's body to slide backward several meters involuntarily!

He carved two deep trenches in the ground, and only managed to steady himself by channeling his spiritual pressure into his legs.

That's a lot of force!

Aizen glanced at his left hand.

His hand was cut open by the black flames clinging to the blade, and blood was gushing from the back of his hand.

"This feeling..." Aizen took a few steps back, observing the black flames in his hand: "It's different from back then..."

"You've gotten stronger again, Asuka."

After devouring Francesca and the evil thoughts of this world, the Devouring Flame in its Devouring state became even more violent.

They are frantically eroding Aizen's spiritual particles, trying to drag him into an endless abyss.

Aizen flicked his hand, using his spiritual pressure to dispel the malice, his curiosity growing even stronger: "As expected, only you can amaze me."

But Asuka had no intention of chatting with him; a barrage of attacks followed in quick succession.

Clang! Clang! Clang!

This time, Aizen no longer acted arrogantly. He used Kyoka Suigetsu to parry Asuka's attacks, and then, in an academic tone, posed a series of questions: "Where have you been for the past eighteen years?"

"The power within you is neither intangibility nor Fullbring... it seems to involve a higher-dimensional concept..."

""

"Can you tell me how you maintain your identity across time and space, and how you got back here?"

Faced with Aizen's incessant questioning, Asuka remained silent, only lingering between Aizen's chest and feet.

The reason is simple: an inner voice had already warned him.

If you absolutely must fight Aizen now... whatever you do, don't look at his sword!

His Zanpakuto possesses complete hypnotic power; once you witness its release, your five senses will be completely dominated.

[To sense the flow of spiritual energy, predict the contraction of his muscles, and fight by instinctively anticipating his killing intent!]

This is your only way to fight him without falling under his illusion spell!

"Bark, you scoundrel!"

With a roar, Aizen unleashed countless black, vicious blades of light from his Zanpakuto, completely sealing off the space around him.

"Unwilling to talk? That's a real shame."

Aizen strolled leisurely amidst the dense flashes of sword light, casually shattering the vicious dogs' attacks.

"Since you don't want to talk, then I'll just have to take you down first, and then slowly dissect and study you."

"Hado #63: Thunder Roar Cannon!"

Without any chanting, blinding golden lightning erupted from Aizen's fingertips, striking directly at Asuka's chest.

The bird did not dodge; the black markings on its body instantly became more prominent.

"Aaaaaah!!"

He gripped the hilt of his sword tightly and, surprisingly, directly met the terrifying beam of the Thunder Roar Cannon with a spiritual pressure slash that gathered all the power in his body!

The black and red slash tore through the air, accompanied by a roar as if trying to sever fate, and collided violently with the golden thunder dragon.

Aizen's gaze changed once again.

There was almost no stalemate.

Asuka's attack was so devastating that it cleaved Aizen's No. 63 Hado, which he had abandoned his incantation for, in two!

The violent black blade light continued its unabated momentum, roaring as it enveloped Aizen's entire body!

"Binding Spell Number Eighty-One: Severing the Void!"

He instinctively raised his hand, creating a huge, transparent defensive barrier in front of him.

This is a high-level barrier capable of completely defending against all Devil Fruits below level 89; it can easily block even a full-force attack from a Captain-level Shinigami...

boom-!!!

The blade struck the broken sky with tremendous force, and the shockwave instantly sent the surrounding rocks flying.

The ground of Twin Phantom Hill began to collapse wildly under the pressure of this force.

The petrel in the distance watched all this, unsure of what action to take.

Go help Asuka? Does she even need my help?

Click...click click click...

A sudden cracking sound rang in everyone's ears.

Aizen stared in disbelief at the Void Barrier, where spiderweb-like cracks were rapidly spreading!

"How is this possible..." Aizen's face, which was always so confident, finally showed genuine shock.

He knew about the bird's special nature; otherwise, he wouldn't have put so much effort into him and the people around him.

But it's only been eighteen years.

Eighteen years ago, he was just a kid with a peak third-class spiritual power. How could he have evolved to this level?

Moreover, even now, there's no sign that his spiritual power has broken through to the third level...

No...it's not just his problem...

Was it his knife?

boom!

Ultimately, the void could not withstand this domineering impact and shattered with a deafening roar.

The remaining black sword energy tore through Aizen's pure white haori, leaving a long bloody gash on his chest.

Using the force of the impact, Aizen drifted backward dozens of meters, looking down at the blood spilling from his chest, his eyes becoming uncertain.

"Surprised, Aizen Sousuke?"

Feiniao stood there, leaning on his raccoon dog, his chest heaving, and finally uttered his first words after their reunion.

Although this attack injured Aizen, he knew that it was of no consequence to this unfathomable man.

He slowly raised his Zanpakuto, the tip pointing directly at Aizen: "The disgusting things you did to me..."

"7

"The pain and despair you inflicted on me..."

"And thanks to you, every day and night I lived like a monster, neither human nor ghost..."

1

"I remember it all, I haven't forgotten it for a moment."

The birds’ voices were hoarse and rough, like the whispers of demons crawling out of the depths of hell.

"Give me back everything you owe me!!"

Before he could finish speaking, Asuka transformed into a black shadow and pounced on Aizen once again.

"...I advise you not to make such a show of bravado when you speak." Aizen brandished his Zanpakuto, smiling as he looked at Asuka: "That will only reveal your weakness."
