Anime/Manga: Bankai Starting with Demon Slayer

Meanwhile, in a dimension so far away from Namimori... and even from the entire country of Japan...

In a pure white, mysterious space, seemingly devoid of any impurities.

A peculiar gaze, too, was quietly cast upon us by the ignition of the Hellfire.

Blan Jesso was comfortably leaning against the soft white sofa.

He rested his chin on his left hand, and with his right hand, he picked up a plump, white marshmallow from the crystal bowl beside him and casually tossed it into his mouth.

"Hmm... the matcha-flavored marshmallows in this world are still a little bit too sweet."

He chewed, his purple eyes slightly narrowed.

On his middle finger, a Marai ring inlaid with wing totems was emitting a mysterious orange light.

As the chosen one of the Marai Rings, Byakuran possesses the terrifying ability to share consciousness with all his parallel counterparts and even interfere across dimensions.

For him, the multiverse is nothing more than a giant library that he can browse at will.

His daily routine consisted of searching on this almost infinite bookshelf for something that could stir up a ripple of joy in his heart, which had long been bored with everything.

Just now, while he was conducting his daily observations of parallel worlds, the Marley Ring in his hand suddenly produced an unprecedented and strange resonance.

It was an abrupt, domineering energy reaction that was completely outside his comprehension of any kind of death flame.

The ripples it produces when it burns can even penetrate the barriers of dimensions, making it hard to ignore.

“What an interesting fire…” Byakuran’s smile gradually widened, and intense curiosity rose in his eyes: “This flame does not belong to the seven attributes of the Great Sky… It seems to burn away all concepts… What exactly is it?”

He closed his eyes and immersed his consciousness in the vast network of the world of thought.

Countless images of parallel worlds flashed through his mind like a revolving lantern.

He tried to find the counterpart of this being who ignited the flame in other parallel worlds.

According to the rules of the multiverse, any person or thing that exists in the main world will inevitably have countless corresponding development trajectories in parallel worlds.

Just as there are countless Sawada Tsunayoshi, there are countless Byakuran.

However, a minute passed.

Ten minutes have passed.

Half an hour later, Bai Lan suddenly opened her eyes.

The nonchalance on his face had completely vanished.

No.

There is nothing.

In the countless parallel worlds he could observe, he couldn't find a single trace of that soul.

The Rainbow Child who ignited the black and white flames seemed to appear out of thin air in this world, completely outside of all world lines!

Bai Lan stared in surprise at the shimmering Marai ring on her finger, a slightly neurotic smile on her face: "A unique copy that doesn't belong to any time or space?"

"This is truly...amazing."

He stood up, his gaze seemingly piercing through the white wall, locking onto a distant coordinate.

"Then I'll go and meet him in person... to see what kind of person this being who defies the laws of the multiverse is."

In the present world, Namimori Town.

This is a rare good day.

Sunlight filters through the lush canopies of trees lining the streets, casting dappled shadows on the clean asphalt pavement.

In the distance, the sounds of students participating in club activities could be faintly heard from Namimori Junior High School, while the aroma of grilled takoyaki and freshly baked bread wafted from the small shops along the street.

Everything was so peaceful.

The peace was so profound that one almost forgot that not long ago, a successor war that nearly upended the entire Mafia world had erupted here.

Asuka, dressed in a small black casual jacket, strolled lazily along the bustling commercial street of Namimori Town with her hands in her pockets.

To be honest, at this moment he looks like a precocious little brat.

Walking beside Asuka was Yugi Muto.

The dueling king who traveled through the portal with him and was trapped here is currently holding a large paper bag printed with the mascot of Namimori Town, with a simple smile on his face.

His gaze swept back and forth among the dazzling array of shops on the street, seemingly fascinated by every unique item there.

"Master Asuka, look at this!" The game stopped in front of a handicraft shop and held up a small wooden bird carving: "This is so exquisitely carved!"

"If I buy these and give them to my grandfather, he will be very happy! Grandpa Shuangliu loves collecting these little trinkets from different places!"

Asuka glanced at the wooden carving, her brow twitching slightly: "...Are you sure you want to buy that, the game?"

He pointed to the extremely small and concealed characters at the bottom of the wood carving: "[Supervised by the Namishō Disciplinary Committee, counterfeiting will be prosecuted]".

"If I'm not mistaken, this should be the product of that always-stern-faced Committee Chairperson, Hibari. It doesn't look like a typical souvenir..."

The game paused for a moment, looked closely at the words at the bottom, scratched its starfish-shaped hair somewhat awkwardly, and chuckled dryly: "Haha... Is that so? But the craftsmanship is indeed very good."

"Actually, I'm still thinking about whether to bring some local Namimori snacks to Jonouchi and Honda, but I don't know if they'll get damaged after going through the time portal."

"Whatever you want... But I'm not bragging, but I'm actually a master in wood carving." Asuka stretched and said shamelessly, "My works have been passed down from the Taisho era to the present day and have become sacred relics."

Of course, he didn't listen to any of his boasting and simply took the wood carving to the boss to settle the bill.

This kid...he really doesn't know what's good for him...

Asuka watched him still picking and choosing in the craft shop, and shook her head in exasperation, wondering if she could pick out something to give to Shinobu.

Yesterday she mentioned the wedding ring...it was indeed her oversight.

You've been together for so long, and you haven't even had a proper ceremony. What kind of relationship is this...?

Just as she was thinking, Asuka's intuition suddenly jumped.

The body, which was originally lazy and relaxed, tensed up instantly in less than a tenth of a second.

He turned his head sharply, his gaze fixed on a figure ten steps away through the shop window.

Chapter 851 Ideas for Solving the Current Crisis

He was a young man wearing white casual clothes.

He had a striking head of short white hair and a purple, inverted crown-shaped mark under his left eye.

At this moment, he was standing in front of a cotton candy stall with his back to the birds and games, holding a pink cotton candy in his hand, about to put it in his mouth.

He appeared to be just an ordinary passerby, a young tourist who could be seen anywhere on this peaceful commercial street.

But in Asuka's keen senses, the aura emanating from this white-haired man was as dazzling as a torch in the night.

This does not mean that his spiritual power is strong or that he is threatening.

The other person exuded a sense of incongruity, as if they didn't belong to this world.

In other words, although the man's body was standing there, the space around him was being distorted at a subtle frequency.

It's like a silhouette that doesn't belong in this painting, forcibly and clumsily pasted here.

That intense sense of disorientation made the bird instinctively wary.

"Stay here and do not move."

Asuka silently warned the game behind her, her right hand already unconsciously resting on her waist.

Although his body has shrunk, the charcoal will also shrink according to his thoughts, and it will not affect its use.

With just a thought, that katana capable of burning everything would instantly tear the enemy apart.

Seemingly sensing the deadly chill behind him, the white-haired man stopped eating the cotton candy.

He slowly turned around, his face showing neither panic nor fear as if he were being locked onto by the murderous aura.

On the contrary, a bright, even somewhat innocent smile graced his handsome face.

Those violet eyes narrowed slightly as they observed the bird, which seemed to be facing a formidable enemy, with great interest.

"Oh dear, oh dear, what a terrible reaction..."

Bai Lan stuffed the pink cotton candy into her mouth and mumbled indistinctly.

He casually clapped his hands, as if he hadn't sensed the murderous aura emanating from the bird that could shatter the surrounding air, and walked over with light steps.

"I originally just wanted to create a natural chance encounter on a street corner, like in those third-rate romance novels... I never imagined your sensitivity to spatial fluctuations would be a million times more exaggerated than I thought..."

"This is really giving me a headache, Mr. One-of-a-Kind Baby?"

"Who are you?" Hearing that the other party was coming for her, Asuka's eyes turned dangerous: "You have ten seconds to explain why you're here, otherwise, I don't mind making you disappear right here on this bustling street."

Although the game didn't have the terrifying perception of Asuka, the keen intuition bestowed upon him by the Millennium Puzzle allowed him to clearly sense the hidden danger emanating from the white-haired man before him.

Without making a sound, he reached into his pocket and grabbed the top of his deck, ready to deal with any potential conflict.

"Don't be so tense. It's a rare holiday for everyone. Fighting and killing would spoil the mood." Bai Lan maintained her smiling demeanor.

He proactively raised his hands to indicate that he had no hostile intentions: "Let me introduce myself. My name is Bai Lan, Bai Lan Jesso."

"She's an ordinary person who loves sweets and occasionally travels around the world."

"Ordinary people?"

Asuka wasn't too satisfied with this answer: "Ordinary people shouldn't have spacetime fluctuations that can cross world barriers, right?"

"Are you sent by the Zero Division to chase me? Or are you one of those remnants of the Ye Wang faction that we didn't wipe out before?"

"Oh dear... what is all this about..." Byakuran waved her left hand, adorned with the Marai Ring, in front of Asuka, her tone becoming slightly more serious: "However, you're not entirely wrong; I do indeed possess the ability to travel through time and space..."

"I came here today with no ill intentions, I'm just... simply curious about you."

Bai Lan's smile faded as she leaned down and stared at the black and white pacifier on Fei Niao's neck: "In this vast and boundless parallel universe where countless possibilities exist, every life is like a leaf on a tree, similar yet not exactly the same... There are countless similar existences."

"But you, wondrous Rainbow Child... in all parallel worlds, you are the only one."

Byakuran extended a finger and pointed it at Asuka's heart: "I just want to see with my own eyes what kind of fascinating qualities this unique book in the entire universe possesses."

Upon hearing these words, Asuka's tense nerves relaxed slightly, and she released her grip on Makoto's hand.

Oh, so they're just natives of this world... What a false alarm.

Although he wasn't afraid of the Zero Division's pursuit, he also felt that they probably didn't have the ability...

But if they really catch up, he's not sure if he's even in his current state to be able to hold his own against the Zero Division.

But since they're locals, things are much easier.

"Alright, now that we've seen the person, is there anything else?"

Asuka gave Byakuran a deep look before resuming her indifferent demeanor.

The other person didn't seem surprised by Asuka's attitude and simply sat down on a chair at the shop entrance: "It's nothing serious, but since we rarely meet, how about we chat a bit more?"

"Did you come to this world from another universe? Or did you use some method to block my senses?"

Asuka put away her hostility and naturally sat down in another chair: "...I can give you a brief explanation of my world, but in exchange, I need you to provide me with information first."

"Oh? Do I have something here that interests you too? That's great."

"You just said that you can interfere with other parallel universes?" Asuka asked.

Bai Lan showed off the Marais ring on her hand and patiently explained, "To be precise, it's about peering into a horizontally unfolding spacetime at the same point in time."

"Although this interference is not unlimited, as long as I find the right frequency, I can read knowledge from other worlds like flipping through a book, and even influence the course of certain events."

As Bai Lan explained, a thought arose in Asuka's mind.

So far, almost all of Asuka's interference in the multiverse has been vertical.

Whether one comes from the past to the present, or goes from the present to Fuyuki, and then returns after more than ten years, it is always the same.

But if the kind of lateral interference that Byakuran described could be achieved...

The aftereffects of that great battle with Ye Wang in Hueco Mundo have been spreading throughout the entire Three Realms, creating a chain reaction.

The world is becoming increasingly chaotic.

If this problem is not addressed at its root, the balance of the world will collapse completely before long.

How can we recalibrate people's perception?

How can we completely erase or quell their memories of that devastating battle?
