Anime/Manga: Bankai Starting with Demon Slayer

The illusory weeping god in his hand, that demonic blade covered in eyeballs, was now completely severed!

On his chest, a deep, bone-revealing burn scar stretched diagonally across his entire torso.

The golden flames clinging to the wound were frantically devouring his cells, making his proud regeneration rate extremely slow.

"Crimson Blade... no, you didn't even let the Nichirin Blade burn? How did you manage that?"

Kokushibo slowly turned around, his six eyes fixed on Asuka, uttering a question he couldn't understand.

His tone was filled with jealousy, but even more so with an almost twisted excitement.

"It seems... I finally have a chance to test my full power in this form..."

Just as Asuka was severely injuring Kokushibo, good news also came from other corners of Mugen Castle.

In the deep corridor, Mist Pillar Muichiro Tokito moved freely amidst Usui Uonuma's attacks, like a wisp of smoke that could not be grasped.

"Damn it! How could you dodge my attacks so easily!" Uonuma Usui, already covered in wounds, went berserk, wildly stabbing everywhere with his short spear.

This place was specially created for him by Naruto, which could block the sight of those human swordsmen, naturally giving him an advantage.

Furthermore, after becoming a Ghost Moon, he can merge his body into the shadows and appear in all sorts of unexpected places. Combined with the dim lighting, he should be invincible.

However, his sneaky fighting style, which relied on the terrain to launch surprise attacks or to defend and counterattack, was completely powerless against the agile Muichiro.

"Excuse me, what's your name again?"

Muichiro's voice was as cold as ice.

"Breath of the Mist - Fourth Form: Flow Slash".

In that instant, a thick white fog, so dense that one could not see their own hand in front of their face, suddenly erupted in the originally narrow corridor.

Although Uonuma Usui is a blind demon, he possesses extremely strong spatial perception thanks to his status as a demon moon.

But now, he felt that his mind was in chaos and he couldn't see anything clearly.

He frantically brandished his short spear, trying to cleave through the fog.

However, in this fog, a ghostly figure silently darted past.

puff--!

The fog dissipated.

Muichiro was already standing behind the ten swordsman, slowly sheathing his sword.

"How... is that possible...?"

Uonuma felt as if his throat was gurgling with blood, and he struggled to his knees.

Muichiro didn't even glance back at the ashes behind him. He simply touched his swollen cheeks, which were covered with cloud-like lines, and muttered to himself:

"There's a very unsettling smell coming from that direction... Is that a bird?"

Chapter 104 You also have a Zanpakuto?

"quack--!!"

"Muichiro Tokito! Upper Moon Five! Defeat him!!"

The ravens that were also transported into the Infinite Castle swiftly traversed the castle, guiding the Demon Slayer Corps members and broadcasting inspiring news to everyone!

Kokushibo, however, turned a deaf ear to it, as if these things had nothing to do with him.

He looked down at the wound on his chest that had been slow to heal and was writhing with flames.

Six eyes held a complex mix of emotions: jealousy, anger, incomprehension, and a martial artist's fervor that finally erupted at this moment.

"For hundreds of years... apart from that person, you are the first human to have driven me to this point."

His voice was no longer calm; each word carried a hum that shook the space.

As he finished speaking, the ghostly aura surrounding him began to expand and surge at a terrifying speed.

"Since your swordsmanship has reached the realm of the gods, then... I shall respond with all that I have as a 'demon'."

Creak—creak—!

The sound of bones shattering came from the direction of Kokushibo.

His body instantly became much stronger, and bone spurs resembling shells even appeared faintly on his back. On his originally cold and resolute face, the veins bulged like black venomous snakes.

As Kokushibo's demonic power was fully released, the long sword covered with eyeballs emitted an extremely mournful hiss.

The original blade began to grow wildly, with bone-like material constantly proliferating outwards from the hilt.

In the blink of an eye, the blade not only grew nearly twice as long, but also sprouted several forked blades diagonally on both sides of the main blade, which were also covered with rotating eyeballs.

It doesn't look like a sword; it looks more like a spine pulled from a hellish demon.

"This is..." Asuka's gaze faltered for a moment, and she spoke with some surprise, "Is your sword also a Zanpakuto?"

"Zanpakuto?" This term was extremely unfamiliar to Kokushibo; he did not understand this name that originated from another dimension.

"baffling."

Kokushibo took a sudden step forward, and the bricks and tiles beneath his feet, now reduced to ruins, instantly shattered.

【Breath of the Moon - Face-Piercing Slash - Moonlit Blade】

The strange longsword swung through the air, instantly unleashing several massive, serrated crescent-shaped shadows that crisscrossed and almost completely covered every blind spot around the bird.

As before, each moon shadow contained countless tiny, blade-like fragments of the moon, only faster, more numerous, and more intense.

This is the power of Hollow Cry God, which can further enhance Kokushibo's already extremely lethal Moon Breathing.

Whoosh—!

The spot where the bird was standing was instantly leveled by several meters.

Although he managed to dodge the attack by using Thunder Breathing and gathering spiritual pressure, his right arm was still grazed by a stray moon-shaped beam, and blood instantly stained his clothes.

"Such heavy sword energy..."

Asuka could sense that not only had the sword in the opponent's hand become longer, but the amount of demonic energy it carried had also increased several times over.

"It seems your blade yearns for my soul." Asuka landed slowly amidst the terrifying wave of sword energy, no longer concealing her imposing aura.

The burning marks climbed up his cheeks, and he released his spiritual pressure perception to the extreme, even seeing Kokushibo's internal organs and bones.

Om-!

A crisp buzzing sound rang out, and the Zanpakuto in his hand began to emit a crimson light.

"As expected, it's the Crimson Blade..." Kokushibo's expression turned serious; he sensed that Asuka's aura had risen to another level.

The two erupted at the same time, turning into two afterimages, one red and one black, and collided violently on the ruins!

Clang! Clang! Clang! Clang!

Having awakened his demon form, Kokushibo's swordsmanship has become so unpredictable that it transcends human comprehension.

The forked blades of that longsword could not only block and slash, but were also short swords that could be wielded independently.

As the bird lunges to the side, the forked blade can even twist strangely, piercing straight into the bird's back.

Asuka, who has mastered all five breathing techniques, is no longer a being that ordinary humans can match.

His spiritual pressure spread out, forming a domain centered on him, where no change in the flow of energy could escape his perception.

Although Kokushibo's sword strikes were extremely fast and fierce, they still couldn't truly threaten Asuka's life.

The two dodged and weaved through the collapsing Infinite City, their two alien blades clashing wildly together.

They fought their way from the dojo to the outer platform, and then fell back down from the collapsed ruins.

The crimson and silver sword light shredded the surrounding Japanese-style rooms and corridors.

The shockwaves generated by each impact were enough to instantly obliterate any evil spirit that tried to approach.

Just as Asuka and Kokushibo were locked in fierce combat, in another corner of the Mugen Castle, the thunderous sound had reached the limit that the eardrums could withstand.

The terrain here is extremely treacherous, a broken space composed of countless fractured corridors, suspended above the abyss.

"Hahahaha! Zenitsu! You haven't changed a bit from looking like a stray dog!"

The beast leaped into the air, the black lightning patterns on its back appearing particularly ferocious in the darkness of the Infinite City.

The Nichirin Blade in his hand was wrapped in jet-black lightning; it was a modified Thunder Breathing technique infused with demon blood.

"See that? This is true power! A power that that useless old man could never comprehend in his entire life!!"

"Thunder Breathing, Second Form: Inari Spirit!!"

Five slashes, crackling with black lightning, arrived instantly, blasting the corridor beneath Zenitsu's feet into pieces.

Not only that, the sword shape of his Thunder Breathing technique kept changing, violently blasting towards Zenitsu, causing explosions in large areas.

Zenitsu rolled around in a disheveled state, his original haori now tattered and his body covered in bloodstains.

The black lightning bolts were extremely corrosive, constantly eroding his life force.

But he remained silent.

Beneath that head of short, golden hair, his eyes were cold and ruthless.

The overwhelming grief made the surrounding air feel heavy.

"Grandpa..."

Zenitsu finally spoke, his voice hoarse and trembling.

"Your grandfather committed seppuku for you..."

"He didn't even have a matchmaker... He died in agony!"

The figure of the beast suddenly paused in mid-air, then revealed an even more maniacal sneer: "He deserved it! That old stubborn man insisted on passing on that inheritance to a piece of trash like you! If he had given me all the essence earlier, how could I have become a ghost?"

"Shut up..."

"What's wrong? Isn't that right? If you're so capable, prove it to me! Prove to me what value this useless old man has in the First Form!"

Zenitsu slowly lowered his center of gravity, his anger finally reaching an unbearable threshold.

He gripped the hilt of the knife tightly, and the scattered arcs of electricity around his body began to wildly contract into the scabbard.

Then, it exploded! It scattered in all directions!

Reach the pinnacle!

"What...what is this?"

Such a display of power sent a chill down even through the demon Yue that had transformed into the Ghost Moon.

He felt a tremendous fear descending upon him, and he frantically swung the demonic blade in his hand, pouring all the demonic power in his body into it.

"Breathing of Thunder - Fourth Form: Far Thunder!!"

A jet-black ball of lightning hurtled toward Zenitsu like a meteorite.

however.

That golden light arrived even before the lightning.

In an instant, the darkness of the Infinite City was completely torn apart.

The Nichirin Blade didn't emit ordinary lightning; instead, it transformed into a colossal dragon constructed of golden thunder, roaring as it swept across the void!

Such speed is so fast that even gravity cannot keep up, and space and even time seem to lose their meaning.

The pupils of the beast contracted sharply.

He didn't even feel any pain; he only saw a golden light, brighter than the sun, slash across his neck.

Chapter 105 You Are My Pride

puff--!

The head, bearing an expression of disbelief and terror, flew high into the air.

"Thunder Breathing, Seventh Form: Fire Thunder God—!!"

"How could this be! This move... why have I never seen it before?!"

"As expected, that old man really did teach you his secret technique! That bastard!!"

As the head of the beast fell into the abyss, it watched the golden figure standing on the broken walls, still in a sword-wielding posture. The jealousy in its heart reached its peak, and it continued to curse.
