Anime/Manga: Bankai Starting with Demon Slayer

As expected of the Demon King, his regenerative abilities are so powerful that he won't die even after being beheaded. Are we going to wait until daylight and let the sun kill him...?

"The ground has vanished! It was Muzan's Blood Demon Art!"

"Protect the knife! Everyone, concentrate and breathe!"

Not only the Pillars, but also the hundreds of Demon Slayer Corps members who were lurking around and gathering in droves, all lost their footing and fell into the abyss amidst the sound of the biwa.

Even ordinary team members, having learned of the existence of the Infinite City through information sharing over the past few days, did not show excessive panic, and instead communicated and issued orders to each other!

Despite being mentally prepared, everyone was still unable to control their endless fall within the gravity-defying, intricate space of the Infinite City.

Due to Naruto's absolute control over space, the Demon Slayer Corps' encirclement was disintegrated as they continued to fall.

Everyone is being consciously guided to different battlefields, and a brutal confrontation is taking shape.

...

In a dark room within the city, reeking of a fishy stench and filled with countless ornate porcelain jars.

Obanai Iguro landed lightly on the crossbeam, her heterochromatic eyes revealing a venomous chill.

The white snake around his neck flicked its tongue uneasily, clearly disgusted by the smell here.

With a muffled thud, Kanroji Mitsuri also landed there.

She gripped the long, supple Nichirin Blade, which resembled a whip, tightly, her eyes revealing an unprecedented determination.

Before the two of them, Tanjiro Kamado had already landed first, the markings on his forehead shimmering faintly.

"You two! The smell here is terrible! It must be an Upper Moon demon!" He quickly ran to Mitsuri's side, looking around warily.

...

In another spacious square filled with suppressed sobs, three figures stood in a triangular formation, surrounding a seemingly thin, terrified old demon—Upper Moon Two, Hantengu.

"Don't kill me... I'm so scared... People who bully the weak are all bad people..."

Half-Heaven Dog huddled in the shadows, weeping, but the evil aura emanating from him made the surrounding air feel heavy.

"Stop talking nonsense! I don't want to hear a single word of your pathetic pleas!"

Shinazugawa Saneya roared, his scars turning red with blood from his anger, forming dark red lines like a windmill.

"Calm down! Shinazugawa! This isn't his true form!" Rengoku Kyojuro stared intently at Hantengu's chest with his owl-like eyes, making the old man feel a chill run down his spine.

Giyu Tomioka remained silent, but wavy lines began to appear on his cheeks, and his deep blue eyes were like a still pond, without any ripples.

...

Deep within the Infinite City lies a corridor shrouded in mist.

There are no lights or light here; you can only see the internal structure by the light from a distance.

A hideous demon wearing an eyepatch, holding a tortoise shield, knelt in the middle of the corridor, grinning wickedly at the person before him—

"Kid, looks like you're the first Pillar to come here to die! I am..."

Before he could finish speaking, the young man before him, the Mist Hashira, Tokito Muichiro, simply tilted his head slightly.

Those mint-colored eyes, always so blank and empty, seemed to completely ignore the demon before them, casting their gaze into the depths.

"Excuse me, could we save some time? Zhu is very busy."

...

In this chaotic fall, one figure stood out as particularly unusual.

My wife is good at ease.

He remained silent, neither letting out his usual deafening screams nor shedding tears of fear.

Her short, golden hair danced wildly in the wind, and her eyes, which had always been filled with timidity, now radiated an extremely suppressed, unfathomable murderous aura.

Zenitsu gripped the hilt of his sword tightly with his left hand, his arm muscles bulging from the effort.

His gaze seemed to pierce through the layers of buildings in the Infinite Castle, locking onto a black-haired demon wearing a black kimono over a Demon Slayer uniform.

Boom!

He landed heavily, his eyes fixed on the pupils of the person in front of him—Upper Moon Six.

...

Clang—!!

As the pipa music faded, the bird's feet gently landed on the simple wooden floor.

This is an astonishingly large dojo, open on all sides, with only a few massive wooden pillars supporting the towering ceiling.

In the very center of this temple, a figure sat upright.

The person had their back to Asuka, wearing a purple plaid kimono, with their long black and red hair tied into a ponytail hanging down their back, and a long sword with an equally strange shape placed beside them.

"Has he arrived? The strongest swordsman of this generation, Arashi."

Chapter 103 Fierce Battle: The Upper Moon

Is it Kokushibo?

Asuka silently drew the talisman.

According to Komashi, of the existing Upper Moon demons, the only one that truly needs to be watched out for is Upper Moon One, Kokushibo.

"He's not an ordinary demon; he's the strongest swordsman in your Demon Slayer Corps, Yoriichi Tsugikuni's older brother." Asuka was somewhat surprised when Komashi said this.

But now, judging from the aura of perfect harmony between man and sword emanating from the other party, this statement is indeed true.

Kokushibo slowly stood up, his movements elegant and deliberate, exuding an indescribable majesty.

He turned around, and on his resolute face were three pairs of golden eyes.

“The rhythm of this breathing…” Kokushibo’s six eyes locked onto Asuka simultaneously, his voice carrying a sense of decay that spanned hundreds of years: “The aura emanating from you reminds me of some…not-so-pleasant things.”

"Are you referring to the Breath of the Sun? Iwakatsu Tsugikuni."

Despite being retorted by Asuka, Kokushibo did not show any strong emotional fluctuations and remained calmly observing Asuka.

Komashi said this guy was petty and easily mocked, didn't he? Asuka frowned.

"A strange knife... a strange power. You're not using pure breathing techniques. What exactly is that chaotic power within you?"

Want to know?

Asuka slowly lowered her body, and beneath her somewhat disheveled black hair, her eyes gradually turned as cold as iron.

"You can try it yourself."

"Xiao Zhi... what an arrogant junior."

Kokushibo coldly drew out the long sword called the Hollow Cry God.

As the blade was withdrawn, countless blood-red eyeballs spun wildly across its surface, while eerie moonlight flowed along the edge.

In the silent Mugen Castle dojo, the hems of their robes fluttered without any wind.

That was the murderous aura swirling between the two.

Clang!

From the very beginning, neither side held back, unleashing swift and ruthless attacks.

Swords clashed, long blades hummed, and the sound of metal clashing echoed through the night sky.

It must be said that Kokushibo truly lived up to his reputation as a swordsman who had honed his skills for hundreds of years. Every move he made was cunning and unpredictable, and he was indeed incomparable to the other Pillars in their training.

He had already thoroughly mastered the swordsmanship of the Demon Slayer Corps.

Even when Asuka uses five different sword styles, alternating unpredictably, he can always find a way to counter them immediately.

"I have only ever seen one human who has mastered breathing techniques and used sword techniques to your level."

Kokushibo unleashed a high-speed horizontal slash that surpassed the limits of the naked eye, carrying countless subtle moon-like blade energy, aimed directly at the bird's throat!

【Breath of the Moon - Dark Moon - Night Palace】

The bird twisted and spun, the raccoon slicing through the air, retaliating with a spiritual pressure strike that sounded like a howling dog!

Boom!

A violent storm of spiritual pressure and the aura of the moon blade exploded in the center of the dojo, instantly turning the surrounding wooden pillars into dust.

That was a clash powerful enough to make the entire Infinite City tremble.

But Kokushibo had no intention of stopping there; the long sword in his hand, covered in eyeballs, was wielded once more—

【Breath of the Moon·Lonely Moon in the Night·Eternal】

A dense barrage of crescent-shaped slashes surged forth like a tide.

This wide-ranging and indiscriminate attack should have instantly shredded the opponent, but Asuka's performance caused Kokushibo's eyes, which had been dead for a hundred years, to slightly narrow.

He moved with incredible ease through the gaps in those crescent-shaped strikes, his movements defying all logic...

If I had to describe it, it would be like walking in the air.

Every time the crescent moon strike was about to hit him, the kid somehow borrowed strength from somewhere and kicked off the ground, dodging the attack.

"How is this possible? Are you human?"

“It’s definitely more human than you.” Asuka remembered Komashi’s advice and kept trying to provoke Kokushibo with words, and attacked him again.

The battle continued, and the entire dojo had been leveled by the sword energy of the two.

A deep gray aura began to appear on Asuka's body, but strangely, his aura not only did not weaken, but became even stronger.

"Your sword is your Blood Demon Art, isn't it?"

Asuka swung her sword down fiercely, and the raccoon managed to cut halfway into the opponent's blade!

A sense of unease rose from his hand, and Kokushibo quickly exerted his strength to shake off the bird, his eyes growing even colder.

This feeling isn't good.

The Hollow Cry God is a demon blade forged from the blood and bones of Kokushibo, capable of regenerating instantly even if severed.

This was originally a weapon that allowed Kokushibo to unleash his sword techniques without worrying about damaging the blade when fighting Demon Slayer Corps swordsmen, but now it has become his biggest problem.

Each time the blades clashed, Kokushibo felt a chill run down his spine.

He had already heard Muzan mention it; the black-haired swordsman in the Demon Slayer Corps could devour demons, which must be referring to this sword.

Each time the tama stole a blade from Kokushibo, it would greedily devour the opponent's demonic power.

Even though Kokushibo had been very careful to avoid any sword wounds, his body was still losing power uncontrollably.

Moreover, the trouble doesn't end there.

Asuka's breathing rhythm was making him increasingly uneasy.

As the battle continued, his initially somewhat clumsy breathing, forced by the intense combat, began to become increasingly refined and profound...

Now, Asuka's self-created Sun Breathing has acquired the oppressive feeling of a blazing sun, making Kokushibo's familiar feeling even stronger.

Kokushibo's six eyes widened simultaneously, and due to excessive shock, his normally calm voice wavered for the first time.

"Whose is this... How did you manage to reach that level?"

The bird's figure disappeared, and the only answer he received was the raging black and red flames that rushed towards him.

No, it didn't disappear.

It was because the speed was so fast that it left a distorted line of fire in the space.

Kokushibo immediately swung his long sword to block.

Clang—!!!

For hundreds of years, he had never felt such an oppressive blow!

The domineering force surged down his sword hilt, causing his bones to crack and pop with loud bangs!

Boom!

The floor of the dojo was completely overturned, and flames mixed with spiritual pressure shot into the sky, dispelling the gloom in the Infinite City.

In that light, Asuka and Kokushibo passed each other.

Kokushibo froze on the spot.
