Anime/Manga: Bankai Starting with Demon Slayer

Although in terms of purity, Rokudo Mukuro's power is more like a soul mutation tainted with the aura of hell, it is undoubtedly a ready-made key.

As the true King of Hell, there's no reason for him to ignore the familiar path before him and foolishly study someone else's system.

Another half day passed, and Chrome was invited to the medical room on the second floor of the base.

In the center of the medical room, Chrome lay quietly on the hospital bed.

The girl's purple pineapple-shaped hair was a little messy, and the black eye patch on her right eye stood out against her pale skin, giving her a fragile and pitiful look.

Beside the hospital bed, Shinobu Kocho stood with her back to the door, her hands hovering above Chrome's abdomen.

A soft green light was continuously flowing from Shinobu Kocho's palm, like a warm stream in spring, seeping into Chrome's body.

This is the Soul Society's healing technique, Reidou.

Although Shinobu Kocho is unable to unleash her Woven Girl in this world where spiritual particles are relatively scarce, her own mastery of the Dao is already quite exquisite.

Noticing Asuka's arrival, Chrome seemed to feel it was a bit impolite to lie there like that, and awkwardly tried to get up to greet her, but was held down by Shinobu Kocho.

"Don't move, the treatment isn't over yet," she said with a smile.

That smile seemed to have some kind of magic, relaxing Chrome's tense nerves and making him obediently accept her arrangement.

The green spiritual energy gradually nourished Chrome's body, restoring some color to her pale cheeks.

Asuka tiptoed over and cautiously asked, "How is she?"

“How should I put it…” Shinobu Kocho frowned slightly. “I just used the Reincarnation Technique to examine her internal organs in detail… Her right eye, as well as most of her internal organs in her abdomen, are indeed missing.”

She withdrew her hands, and the green light dissipated into specks of spiritual energy in the air.

"From a medical perspective, the fact that this child is still alive is a miracle in itself."

Asuka had already heard this from Reborn.

It is said that this little girl lost her right eye and internal organs in a serious car accident, and her life was forcibly maintained by organs created by Rokudo Mukuro using illusion magic.

Shinobu Kocho sighed softly and reached out to smooth Chrome's stray hairs: "...That guy named Rokudo Mukuro, his power is truly unbelievable. He can actually condense illusions to the point that they can replace real flesh and blood."

"But organs created by illusion are ultimately just illusions, and there will always be rejection and friction between them and the real body."

"This rejection reaction is constantly consuming Chrome-chan's life force, leaving her body in a state of extreme weakness and overload for a long time."

Shinobu turned to look at Asuka, her tone tinged with regret: "Although my Return Path can greatly stimulate her cell vitality and repair her damaged meridians... it cannot regenerate the complex organs she has lost out of thin air with the power of the Return Path alone."

Chrome did not show any sadness in response to these words.

For her, being able to maintain this life-and-death bond with Lord Mukuro was the very reason she lived.

“Doctor, you’ve helped me so much…” Chrome said softly, her eyes shining with gratitude. “My body… feels much lighter than before, and that heavy feeling that was always pressing on my chest is gone… Thank you so much, Doctor.”

"I'm glad I could help you." Shinobu Kocho smiled and patted the back of her hand, then stood up and made room for Asuka: "Alright, I've suppressed the potential for internal injuries."

"Next, it's up to Asuka... But Asuka, you're not allowed to bully Chrome-chan, okay?"

Shinobu Kocho walked to the side to organize the medical equipment, then quietly left the room, leaving the two of them alone.

With Shinobu's comfort and the relief she felt, Chrome's unease about Asuka, this stranger, dissipated considerably.

She blinked her intact left eye, looking at the black-haired young man in front of her with some curiosity.

Asuka didn't beat around the bush and went straight to the point about her purpose.

"I need to ignite the flames of death, but my energy structure is somewhat special, and conventional activation methods are ineffective for me."

Asuka raised a finger, and a faint, dark red light could be seen flickering at the fingertip, but it was only a faint glimmer: "During the previous battle of mist, I observed you and know that you and the man inside you possess a power similar to the Six Paths of Hell."

"I would like to ask you to teach me, or let me experience firsthand, how you wield the Dao power."

Chrome paused slightly upon hearing the words "six realms of reincarnation" and "hell".

She lowered her head and looked at the Vongola Ring of Mist that emitted a faint glow on her finger.

"...I don't actually fully understand Lord Mukuro's power." Chrome's voice carried a hint of apology as he tried to explain to Asuka, "I'm just a vessel, a medium through which Lord Mukuro's power manifests in the mortal world...When Lord Mukuro needs it, he will use me..."

Perhaps it was because of Asuka's boldness, or perhaps it was because of the warm atmosphere that Shinobu Kocho had just created, but she seemed to have opened up.

In the ensuing casual conversation, Chrome intermittently recounted some things about Kokuyo Middle School, Kakimoto Chikusa, and Joshima Inu.

Feiniao was not impatient; he listened patiently, occasionally interjecting a few words.

He keenly sensed that this seemingly fragile girl's heart was actually completely occupied by the man named Rokudo Mukuro.

"So, whether we can borrow that power depends on that pineapple-head's mood?" Asuka said half-jokingly.

The moment he finished speaking, the air in the entire medical room suddenly became thick.

A thick, indigo-blue mist seeped out from somewhere and spread rapidly along the ground.

“Kuhuhuhu....."

A sinister laugh suddenly came from Chrome's throat, echoing in the room.

The next second, her timid and gentle expression vanished instantly.

The black eye mask had fallen off at some point, revealing a blood-red eye that shimmered with an eerie red light.

In the pupils of his eyes, a jet-black Chinese character, "六" (six), was clearly etched.

"I heard you were looking for me?"

Chapter 846 The Sorcerer of Hell

Asuka looked at the possessed girl in front of her, her gaze lingering on her heterochromatic pupil for a moment before moving away.

"Rokudo Mukuro".

"Oh my, you little brat know my name?" Rokudo Mukuro tilted his head slightly, his lips seemingly smiling, but his eyes held no mirth. "Did Sawada Tsunayoshi tell you? Or was it that little baby Reborn?"

However, he noticed that the baby in front of him also had a similar yet unfamiliar pacifier hanging around its neck...

The number in his pupils flickered, changing from six to one.

"...You're also a Rainbow Child?"

Asuka thought for a moment: "I guess so."

"You could say that?" Rokudo Mukuro looked at him with amusement. "That's not a very professional answer."

Asuka ignored his teasing and went straight to the point: "Let's get down to business. I came to you because I need your help."

Rokudo Mukuro jumped off the hospital bed and squatted down in front of Asuka: "Kuhoho... Did you need my help? Did Sawada Tsunayoshi promise you something?"

"Don't misunderstand, the reason I wear that ring is simply because I need to utilize the power of the Vongola... There has never been a superior-subordinate relationship between me and them."

He spread his hands, making a gesture to send the guest away: "If it's something troublesome, please leave... while I'm still in a good mood and haven't dragged you into an endless nightmare."

Despite Rokudo Mukuro's sharp warning, Asuka's expression remained unchanged.

"Whether you use the Vongola or don't obey anyone, I don't care."

He had no intention of keeping us in suspense and laid it all out: "I just want to study the Six Paths Power you use to simulate the activation effect of the Death Flame."

After a long silence, Rokudo Mukuro let out a soft chuckle.

The laughter didn't seem like a pretentious gesture; it sounded more like genuine amusement.

"...You've got quite the nerve." Rokudo Mukuro covered his face with one hand, his crimson eyes peeking out from between his fingers. "Do you even know what the Six Paths Power is? It's not some technique you can just 'borrow'..."

"That's something I forged at the end of the cycle of reincarnation... through countless deaths and rebirths."

As he spoke, the numbers in his right eye began to jump rapidly, from six to five to four, each jump making the surrounding indigo fog thicker.

Rokudo Mukuro was right; this is indeed not a power that can be learned later in life.

This was actually a brutal human experiment conducted on Rokudo Mukuro by his family, the Estraneo family, where he was forcibly implanted with a strange eye containing his memories of his past life and information about his afterlife...

Rokudo Mukuro's voice lowered, filled with hatred and regret for the past: "If you think you can learn it just by watching... you're being too arrogant, baby."

As soon as he finished speaking, the entire room collapsed in an instant.

The surface transformed into a boiling sea of ​​blood, from which countless pale, skeletal claws emerged, attempting to drag the bird into the abyss of illusion from which there was no return.

Faced with this terrifying illusion that could drive an ordinary person to the brink of mental collapse, Asuka simply took a step forward calmly.

Snapped.

Asuka grabbed Rokudo Mukuro's wrist.

“You’re right, the power of Hell isn’t something you can just master casually.” Asuka looked at Rokudo Mukuro in front of her with a serious expression. “So I’d like to show you.”

"What is real hell?"

Boom!

As Asuka's voice fell, a blinding blood-red light suddenly erupted from the bottomless abyss of illusion!

An immense and ancient aura, not belonging to this world and far beyond Rokudo Mukuro's comprehension, flowed through Asuka's palm and directly into the depths of Rokudo Mukuro's soul!

The space shattered.

One second ago, they were in the medical room of the experimental base.

The next second, Rokudo Mukuro found himself standing on a dark red ground.

There were no sun, moon, or stars in the sky, only huge cracks crisscrossing like scars, and a blood-red waterfall hanging upside down in the sky.

The ground was covered with layers upon layers of ashes made from countless crushed bones, and stepping on it produced a chilling crunching sound.

"Where...where is this?!"

Rokudo Mukuro abruptly shook off Asuka's hand and immediately took several steps back.

His right eye darted around frantically, trying to decipher the scene before him.

As a sorcerer standing at the pinnacle of the illusion world, he firmly believes that there is no disguise in the world that he cannot see through.

No matter how hard he tried to activate his mental power, the feedback from his right eye made him feel as if he had fallen into an ice cave.

There were no flaws.

Every grain of ashes here, every wisp of cold wind brushing his cheek, even the oppressive miasma that made it almost impossible for him to breathe, all told him one thing—

This is true.

This is not an illusion that any sorcerer could weave; it is a real, eternal prison.

Welcome to my world.

Beneath this sky and earth, the birds are no longer in the form of infants, but are floating in mid-air dressed in long black robes.

Because this is the core of his inner hell, his truest nature.

As for the scenery of this hell, it is quite different from the hell he has modified. It is the more desolate side that he deliberately showed to Rokudo Mukuro.

Rokudo Mukuro's breathing began to become rapid.

His right eye, which was originally marked with Chinese characters, was now experiencing uncontrollable stinging pain.

"Bluster..." Rokudo Mukuro suppressed the fear in his heart and sneered, "You think you can scare me by creating such a realistic scene?"

This guy... is really stubborn.

I originally thought that by showing the hell core inside my body, I could make the other party understand that I wasn't just talking.

I didn't expect I'd have to show my true strength first... This is really troublesome...

Snapped!

Asuka snapped her fingers.

Boom!

The nearby Bone Mountain suddenly trembled violently.

Then, it exploded from the inside.

Amidst the flying bone dust and dark purple miasma, several figures, tightly bound by thick black iron chains and radiating terrifying pressure, slowly appeared in Rokudo Mukuro's sight.

He was a man with dazzling blond hair, covered in wounds.

Even in the darkest depths of hell, even with his limbs, neck, and even his torso pierced and bound by hellish chains, he still held his head high.

Those scarlet snake eyes revealed an absolute arrogance that seemed to come from being born above all things.

“Miscellaneous cultivator....."

The man's voice was filled with murderous intent as he stared intently at the birds in front of him. His arms, which were chained together, suddenly struggled, creating a loud noise.
