Crossover Anime: Starting with Bankai from Demon Slayer

Chapter 285 Chaos is the ladder to progress.

Where is Captain Mayuri Kurotsuchi? Why isn't he in charge of any management work?

Nika was initially worried that she would be questioned and had even prepared herself to deal with the guards.

She discovered that she had been worrying for nothing.

In such a chaotic situation, no one even gave her a second glance.

"Um... I'm from the Fourth Division, here to deliver..." Nika tried to stop a passing researcher.

"Go file this yourself! Can't you see I'm busy?!"

The researcher with the explosive hairstyle didn't even turn his head. He shoved Rika aside, grabbed a pile of parts emitting black smoke, and rushed to the other end of the corridor.

He was still yelling, "It collapsed again over there! My observation data!!!"

Nika stood there, stunned, and blinked.

Although she didn't know exactly what had happened, the chaotic situation was a godsend.

She pricked up her ears, trying to glean useful information from the chaotic shouts around her.

"...Abnormal spiritual pressure field fluctuations... Could it be another spiritual disaster of that magnitude...?"

"Damn it, why did this traveling monster have to come and cause trouble at a time like this..."

'

"Forget about those invaders. As long as they don't get here, we shouldn't waste our computing resources!"

It turned out to be the case.

Listening closely, they seemed genuinely overwhelmed with work.

Some people are calculating for potential spiritual disasters, while others are focused on detecting abnormal spiritual pressure fields.

Others, however, stared intently at the wave pattern that Nisaka couldn't discern any difference from, seemingly trying to find some clue.

Hinata understood.

For these mad scientists, a sudden discovery of anomalous data was far more important than the tedious physical task of guarding the Spirit Court.

"It's not easy being the eccentric chief, he's so busy every day," Nika murmured.

Since everyone is so busy...

""

A slight upturn at the corners of her mouth revealed a slyness that belied her youthful appearance.

So he pretended to be delivering documents, but actually blended in with the crowd and entered the inner area.

Then, at a secluded corner where no one was watching, he silently slipped into the passage leading deep underground.

That place is an absolute forbidden zone that only senior researchers and team leaders can enter; it is so intricate and easy to get lost there.

But Aizen had already given her a map of this place.

Eighteen years ago, in a place called Tsubasa Hill, Kisuke Urahara and Mayuri Kurotsuchi made a secret deal.

Mayuri Kurotsuchi wanted to create a perfect life form with infinite evolutionary potential, even one that could surpass the limits of Shinigami.

The core data on soul enhancement and artificial body technology provided by Kisuke Urahara completed the final piece of Mayuri Kurotsuchi's puzzle.

He threw himself into the experiment without stopping, but still encountered a fatal bottleneck: the paradox between the stability of the spirit core and the unlimited growth of spiritual pressure.

At that time, the proud and arrogant Mayuri Kurotsuchi made an unexpected move.

Not only did he ignore Urahara Kisuke's warning, but he also provocatively approached Aizen because of Urahara's words.

That night, Mayuri Kurotsuchi slammed a thick stack of data onto Aizen's desk.

He didn't ask or discuss it; he simply commanded in a matter-of-fact and arrogant tone, "Aizen, I've read your thesis on spirit particle construction at the Shinigami Academy."

"Although it's full of amateurish naiveté, it still has some reference value... to help me complete the spiritual pressure circuit design for this body!"

He offered no explanation or promise of any reward, as if participating in his experiment was an unparalleled honor.

Aizen maintained his gentlemanly demeanor, pretending to be very reluctant as he accepted Mayuri Kurotsuchi's invitation.

For several years, Aizen was deeply involved in the construction of Sleep No. 8 as an assistant, and from time to time he offered some guiding suggestions to help Mayuri Kurotsuchi advance the experiment to this point.

Everything is for today.

The light in the passageway grew dimmer and the air grew colder.

The surrounding walls were covered with various thick pipes, through which glowing liquids flowed, making gurgling sounds.

Finally, Nika stopped in front of a huge metal door.

There was no keyhole on the door, only a row of complex spirit locks.

Normally, without a password, cracking this lock would require a great deal of time and extremely high levels of demonic cultivation.

But today, Lady Luck seems to be on her side.

Perhaps it was because the internal experiments had reached a critical stage, or perhaps the external unrest caused instability in the energy supply, or maybe it was an oversight by a careless experimenter...

The door wasn't completely closed; it was ajar.

Rika held her breath and squeezed into the gap from the side.

Before her was a huge circular laboratory, surrounded by all sorts of sophisticated instruments that she couldn't understand.

In the very center of the laboratory stands a huge cylindrical culture chamber.

The pale green nutrient solution flowed slowly in the chamber, with countless tubes inserted into it.

Enveloped in the nutrient solution, a curled-up figure floated.

She was a little girl who looked only six or seven years old.

She had short black hair, pale skin, and her eyes were closed, making her look like a sleeping doll.

She possessed no vitality whatsoever, yet emanated a pure spiritual pressure that was unsettling.

This is... Sleep No. 8.

Mayuri Kurotsuchi, drawing upon his life's knowledge and combining it with Kisuke Urahara's techniques and Aizen's "flash of inspiration" suggestion...

An artificial Grim Reaper was created based on the Nemesis No. 7...

The laboratory was empty at the moment.

All the researchers seemed to have been urgently summoned to process other data, leaving this unfinished masterpiece silently suspended in the silence.

Rixiang took a deep breath, suppressed her wildly beating heart, and quickly walked to the incubation chamber.

She took out the crystal that Aizen had given her from her bosom.

The crystals emitted a faint blue glow under the dim light, as if echoing the life within the culture chamber.

"Aizen-sensei said...we should put this in..."

97

Rixiang's hands trembled slightly.

She didn't know what the crystal was, nor what specific effects it would have on the sleeping girl.

But she wasn't stupid; she could vaguely guess something from her teacher's attitude of wanting to oppose the Soul Society...

You possess the power to change all of this, Nichika.

"For a new world."

Rihka gritted her teeth, her eyes hardening.

She reached out, gathering spiritual energy at her fingertips, and gently pressed them onto the control panel of the incubation chamber.

With a slight buzzing sound, a delivery port on the side of the culture chamber slowly opened.

Nika placed the crystal in, and it slid down the pipe into the pale green nutrient solution.

Through the thick, special glass, Nika watched as the crystal slowly rose into the liquid, eventually hovering over the chest of Sleep No. 8.

In that instant, countless images flashed through her mind.

There is the gentle yet always worried look in Lord Ren's eyes, the parents' yearning for peace yet having to live cautiously, and Brother Xingming's silent chanting of sutras in the courtyard every night.

She still remembers that night many years ago at the Ubuyashiki mansion.

In their struggle against the terrifying progenitor of demons, their family nearly fell into hell...

The memory of being engulfed by flames, the intense pain, the helpless despair... is still vivid in my mind.

Now, although the Soul Society has taken in their family, and although the Fourth Division has given her and Hinai a place to stay.

But Aizen-sensei is right.

They are outcasts from another world.

Perhaps one day, my family will also end up here, subjected to scrutiny, because of a single document from the 46th Chamber. After all, those nobles don't consider the residents of Rukongai to be human beings...

Those guys are even more terrifying than the progenitor of demons.

"I must change this world..."

Rixiang clenched her fists as she looked at Mianba No. 8.
