Anime/Manga: Bankai Starting with Demon Slayer

Because even the birds don't know.

Moreover, this memory only extends back to when Asuka was fighting in the Mugen Train.

Aizen knew nothing about his later experiences, including how he opened the gate.

Compared to this, things like the hypocrisy and the like seem less important now...

"Captain Aizen? Are you alright?"

Silver-haired Gin Ichimaru approached with a smile, noticing that Aizen was unusually quiet today, seemingly lost in thought.

Is this an opportunity?

He thought about it for a while, and finally shook his head in his heart.

Aizen realized he had lost his composure, let out a soft sigh, and regained his composure, even adding a meaningful smile.

"No need, it's not the right time yet."

Aizen gently pushed up his glasses, a cold glint flashing in the lenses: "Look over there..."

“That is…” Tosen Kaname tilted his head slightly, his expression turning serious.

In the center of the battlefield, Shiba Isshin is struggling to carry the unconscious Asuka on his back.

"Hey, little girl, can you still walk?" Yixin turned back to look at the girl whose shoulder was bleeding, his tone full of concern: "By the way, what kind of power do you have? It looks really powerful!"

The girl paused, seemingly struggling with her thoughts for a long time before finally speaking:

"My name is Masaki Kurosaki, and I am a Quincy!"

Quincy are the mortal enemies of the Shinigami, and there exists an irreconcilable feud between them.

Masaki hesitated for a long time before making this answer, but ultimately chose Tanzan.

Upon hearing this answer, Shiba Isshin was clearly stunned, which made Kurosaki Masaki a little nervous.

"Really? So you're a Quincy? This is the first time I've ever seen one. I feel like I've hit the jackpot!"

Huh? Didn't I say...?

"My name is Shiba Isshin! Anyway, thank you so much for today, Quincy girl!" Isshin bowed gratefully and quickly said, "Shouldn't you see a doctor? This injury..."

"I'm fine, Mr. Shiba... Compared to me, your companion seems to be dying..."

Isshin also noticed this.

Asuka's current situation is extremely strange; his spiritual pressure is rapidly declining.

The spiritual power she just displayed... was practically captain-level, but now she's as weak as...

誰！

Just as he was about to use Shunpo to take the bird away, two figures wearing black cloaks suddenly blocked his way.

"Oh dear, Shiba family, fighting in this condition will cause wrinkles."

A voice, both extremely frivolous and yet exuding an unparalleled sense of composure, rang out in the rain.

The cloak was lifted, revealing a green and white striped hat.

Kisuke Urahara lowered the brim of his hat, obscuring most of his face, and the folding fan in his hand covered the corner of his mouth, leaving only his sharp eyes flashing in the shadows.

"Who are you?" Shiba Ichishin didn't recognize the person in front of him and looked at him warily, but his wariness vanished instantly after seeing another face.

"Night... Night One, the boss!!"

As a member of the Shiba family, he naturally recognized this famous commander of the four noble clans.

"Hey! You brat from the Shiba family!"

Another cloak was also lifted, revealing a head of signature long purple hair and golden vertical pupils.

Yoruichi Shifūin stood with his arms crossed, looking down at his opponent with a smug grin, revealing his fangs, his tone carrying his usual authoritative air:

"Long time no see, you're still as reckless as ever!"

.....

"I didn't expect it to be Kisuke Urahara and Yoruichi Shifuin... So they're in Karakura Town... Looks like tonight's viewing party is going to be a success!"

Aizen turned around, his cloak billowing in the wind and rain: "It's not the right time yet. It's better not to expose ourselves to them."

"Is it okay? As long as we act together, maybe..."

“No need, Gin.” Aizen interrupted him with a smile, his gaze deep: “I want to see what changes will occur to Number 78 under Urahara Kisuke’s observation.”

"Although it deviated from the original goal, it also surpassed the original goal..."

"Let's retreat. Tonight's experiment... has yielded more valuable data than we expected."

Three figures, concealed by cloaks of spiritual pressure, vanished silently into the darkness, as if they had never existed.

Chapter 128 Lies and Secrets

"Well then, you're in charge of cleaning up the mess, kid from the Shiba family~"

Big Sister.....

Standing outside the main hall of the First Division barracks, Shiba Isshin's mind was still replaying the other person's words from that night:

“We’re taking this young man with us. If you take him back, all that awaits him is the Technical Development Agency’s dissection table.”

"Remember to think carefully about how to fool that old man Yamamoto."

What exactly is going on between the two of them...?

Even when he was just a mischievous kid, he had heard that name countless times—Yoruichi Shifūin.

She was a true prodigy, the head of the Shifuin family, one of the five great noble clans, and the leader of the Heavenly Armored Guard.

When he was only in his twenties, and had not even mastered the initial release, the woman revered as the 'God of Instantaneous Release' had already reached the pinnacle of power.

Sometimes, after he got into trouble, they would even grab him by the collar and throw him back into the Zhiba family's yard like a kitten.

Yet this very person committed the most serious defection case in Soul Society's history over the past century—

The main frame used in the bokeh experiment is...

However, this perception was shattered that night.

As the head of a branch family of the Shiba family, Isshin is not entirely ignorant of the darkness within the Soul Society.

Although the Shiba family has gradually become marginalized from the core of the five great noble families, he still knows a little about the secrets and taboos that flow in the shadows.

The leader of Night 1 doesn't seem to be what they say she is...

What exactly is going on here...?

"Oh! Isshin, you're here so early?"

A lazy voice interrupted Shiba's deep thoughts.

He turned around and saw a middle-aged man wearing a straw hat and a pink feather cloak covered in patterns, walking lazily by with his hands tucked into his sleeves.

"It's getting late, Captain Chunshui, we're the only ones who haven't gone in yet."

"Oh? Is that so? Haha."

The person who arrived was Kyoraku Shunsui, the captain of the 8th Division.

He flicked his wavy hair, gave a few embarrassed dry laughs, and beckoned Yixin to join him in entering the main hall of the team quarters.

Sunlight streamed obliquely across the floor, illuminating the room...

"Since you're here, why are you sneaking around outside?"

The old man in the central seat of the room slowly opened his eyes. His aged eyes were not cloudy, but rather revealed a profound depth that could see through the years.

Genryusai Shigekuni Yamamoto, founder and captain of the 1st Division of the Gotei 13.

His wrinkled face betrayed no emotion; he simply leaned on his cane and looked at the two people who entered.

"Oh dear, don't be so strict, teacher. Yixin has just recovered from her illness..."

"You too, Chunshui. Also, we're in a meeting right now."

"...Yes, Captain."

Kyoraku Shunsui and Asashiba Isshin shrugged and stood aside helplessly, seemingly indifferent.

However, when he passed by his friend, the white-haired Captain of the 13th Division, Jushiro Ukitake, the latter still saw the cunning in his eyes.

"Is it because Captain Shiba is going to be questioned today that Shunsui deliberately arrived late to share the burden with him...?" Ukitake Jushiro wondered.

Because they failed to report to the Commander-in-Chief after receiving the investigation order and instead launched a unilateral attack on the mortal realm, four team members were killed...

That could also be considered a fault of not weighing more than two ounces...

"Then, let's begin. Captain of the 10th Division, Shiba Isshin."

"Yes, Captain."

Shiba bowed slightly, but the horrific scene of that rainy night a few days ago involuntarily surfaced in his mind.

"Regarding the unusual individual that appeared in Naruki City, it's a humanoid Hollow that has never been recorded before." He spoke calmly, slowly reciting the script he had rehearsed countless times in his mind: "Its characteristics include being completely covered in black armor and possessing extraordinary combat instincts..."

Isshin recounted in detail to the Captain-Commander his battle with Hollow White, the abilities Hollow White displayed, and how he was ambushed by a Zanpakuto from an unknown location.

"A sneak attack?"

A captain wearing a strange hat and with his face painted black spoke in a sinister tone, sending chills down one's spine: "What kind of person could ambush a captain without making a sound? Could it be that there's a traitor among us? Or is it that Captain Shiba's vigilance is too poor?"

"In the end, your failure to retrieve that fictitious sample is already a major sin."

He is the current captain of the 12th Division and the current director of the Technology Development Bureau, Kuru.

Opposite Kumari, a tall man with a strange hairstyle and an eyepatch over his eye—the Eleventh Division Captain Kenpachi Zaraki—snorted coldly, seemingly indignant at such despicable tactics.

"An enemy that can put Captain Shiba in a tough fight..." Third Division Captain Gin Ichimaru interjected with a smile, his fox-like slit eyes revealing a dangerous, playful glint: "Oh dear, the human world is truly a terrifying place, isn't it, Captain Aizen?"

"Captain Shiba's ability to repel this unknown threat has already rendered a service to Seireitei."

Aizen spoke gently, his tone full of camaraderie: "It's a bit of a pity, but it's good that you're back safe and sound."

Upon hearing this, Shiba gave him a grateful look.

In such a high-pressure interrogation environment, having a team leader with a gentle personality step in to smooth things over really relieved his stress.

Apart from that, the other captains did not express their opinions on the matter, but simply waited quietly for Captain Yamamoto's orders.

Captain Yamamoto, seated at the head of the table, fell into a long silence.

After a long while, the old man narrowed his eyes, his gaze sweeping thoughtfully over Yixin:

"I understand."

"Shiba Isshin, although you should be punished for acting on your own, you did make a decisive move and minimized the damage to the world, which is truly commendable."

"Therefore, your violation of team rules will not be pursued."

"Yay!... Uh, no... Thank you so much!!"

Shiba, somewhat embarrassed, revealed his true feelings and then bowed to the captain.

“However…” Captain Yamamoto changed the subject, looking into Isshin Shiba’s eyes: “Your report only mentions this one fictitious case. Are you sure there’s nothing else unusual?”

He did indeed conceal many details.

Regarding that Quincy girl, Masaki Kurosaki.

Regarding Kisuke Urahara and Yoruichi Shifuin.

And that Asuka from the Fifth Division, whom he still can't figure out...

Thinking of this, he also took a special look at the Fifth Division Captain, Aizen Sousuke.

The other person was still the same gentle and refined person, with a kind of gentleness that bordered on weakness, and was looking at him with a smile.

"...Yes! Nothing was missed!"

The order to adjourn the meeting was issued, and the team leaders dispersed in twos and threes.

As Isshin walked out of the hall, he looked up at the sky of Soul Society, but his heart was filled with thoughts of the people in the other world.

"Masaki... and the boy named Asuka... are you alright...?"

In this world, Karakura Town.
