Aizen had no prior knowledge of Hell, but through various documents and reading the Great Spirit Book Gallery of Soul Society, he gained a basic understanding of Hell.
Long ago, in the Primordial World where there was neither birth nor death, Hell was a place known as a pit.
It means that once you break in, an ordinary person can never get out; it's no different from falling into a pit.
Aizen was very interested in the methods of trapping people in Hell, but there were no specific documents documenting them.
Upon arriving here, Aizen discovered that this was achieved by granting immortality.
However, this immortality differs from the immortality understood by the world, which is not necessarily a good thing.
Like Soul Society, Hell is also composed of Reishi. However, unlike Soul Society, there is only one type of Reishi Reishi Hell.
Once people die here, whether voluntarily or involuntarily, the moment their chests are torn open, the Reishi of Hell surge in, transforming into black, liquid-like chains that cover their bodies.
That Reishi was like the lonely Reishi emanating from some lonely creature, freeing Szayelaporro from his fate of emptiness. Hatred and anger poured out of his body like tears, and the Hollow Hole became a huge ring around his body.
Ironically, the ring is pure white, which clashes drastically with the black of Hell.
Aizen once tried to kill Szayelaporro and then watched him resurrect from his chains.
It's not complicated; it simply involves pulling some uncorrupted Reishi back onto the Hell Reishi and recombining them.
Furthermore, depending on their Reiatsu, those corrupted by Hell exhibit different behaviors.
Sinners with weak Reiatsu are corrupted by Hell and can no longer maintain their human form, becoming low-ranking jailers who obey the orders of high-ranking jailers.
This place is similar to Hueco Mundo Hueco Mundo, but even more brutal; here, even death is a luxury.
According to records, sinners who are killed by the Shinigami Zanpakuto are sent here.
So how is this standard for judging a sinner determined?
Aizen was very curious about this, but he had to postpone dealing with it. Compared to those things, what he needed to do at the moment was to integrate Hell.
This is no easy task, nor can it be accomplished by force. These guys are immortal; what good is superior brute force? Imprisonment? Torture?
This is not just one person, but millions upon millions of people.
If Aizen uses those methods, it might drag on for ten thousand years. By then, new people will emerge, and they'll never be able to leave this Hell.
He could only resort to fulfilling his dream by gradually gathering subordinates to achieve his current scale.
Now he is about to meet the former first 6th Division.
"Hasn't that bastard arrived yet?"
Saitō Furofushi, kicked over the wooden table in a fit of rage, his face contorted with fury, as if he were about to draw his sword at any moment.
"I apologize for the slight delay, Captain Saito."
Aizen's voice was refined, showing no sign of any negative emotions due to the tightness in his chest, as he strode into the simple hall carved out of the mountainside.
His azure, childlike eyes gazed at the petite woman before him.
Saitō Furofushi, is a short man of about 1.5 meters tall. Despite his small stature, he exudes a powerful aura and wears high purple twin tails.
Half of his face was covered by black chains, and his left hand had turned into a skull, with lingering black phosphorescence on its surface.
She was still wearing her Shihakushō, a sleeveless Captain's Haori. The Shihakushō, invented by Senjumaru Shutara, could penetrate into a person's soul and form clothing with Reiatsu, ensuring that a person would never be beaten naked.
Exhaustion of Reiatsu is an exception.
"Ha, the man who once destroyed Soul Society actually calls me Captain Saito, how modest of him."
Saitō Furofushi, she no longer needs an eyepatch for her left eye; the black chain acts as an eyepatch covering her left eye socket. She jumps onto the table, swinging her legs, and asks, "What do you want, kid?"
"I want to unite the power of Hell, and I hope you will join my ranks."
Aizen stated his demands directly.
Saitō Furofushi, laughed, throwing his head back and laughing loudly, "Haha!"
She had a habit of laughing loudly, always sticking her tongue out to mock others, "You're such an arrogant brat, trying to recruit me?"
Kid, even if you kneel down and beg to lick my toes, I'd still find your mouth disgusting. Get lost!
A violent Reiatsu swept across Aizen's face, but he remained unperturbed, instead offering a refined smile as he said, " Saito, that's your real name. The name of the District 80 of the East Rukongai is Saito."
You refer to yourself by that district name, and the "Furofushi " part is a name you came up with yourself.
Saitō Furofushi, revealed a mocking smile and spread his hands, saying, "Now I have obtained the Furofushi I desired."
No, this is not your dream.
Aizen shook his head and said with certainty, " Saitō Furofushi. I've read your file carefully. How could someone who craves Furofushi lead the charge and fight desperately?"
You longed for death, but no matter what you did, you couldn't die. No one appeared who could kill you until you met Genryūsai Shigekuni Yamamoto.
Saitō Furofushi's smile gradually faded, turning gloomy. The feeling of having one's thoughts seen through was extremely unpleasant.
She pursed her lips, recalling her first encounter with Genryūsai Shigekuni Yamamoto.
It was an ordinary morning. She did what she always did, randomly picking a noble family in Rukongai that she didn't like and killing them.
At that time, there was no Seireitei, only the Shin'ō District, but that was the territory of the Five Great Noble Clans and some other noble families. Most of the noble families were scattered throughout the various Rukongai.
The nobles controlled their own territories and possessed extremely powerful fighting forces.
Those who could originally be called nobles were born with Spiritual Power stronger than souls from the World of the Living.
Saitō Furofushi and has forgotten whether he is a fallen nobleman or a foreign soul, but without his memories, he is treated as a resident of Rukongai by the nobles.
She didn't care.
When she was very young, she survived by stealing water.
Her first murder was for survival; she killed someone for half a steamed bun.
That feeling was unpleasant, as if I had become a wild beast that only wanted to survive.
Saitō Furofushi, has become the kind of person that people used to hate the most. He wants to die, but he also thinks that suicide is too lame.
Therefore, she often acts recklessly, wanting to die at the hands of others, but due to her powerful Reiatsu, she kills them time and time again.
Hundreds, thousands of people—the corpses of the slaughtered piled up like mountains.
Standing atop the mountain of corpses, she considered giving up for the first time, and named herself "Furofushi" to mock others.
Later, I heard that there was a monster woman named Yachiru in North Rukongai.
Driven by the desire to kill that woman, she embarked on her journey, but due to her unfamiliarity with the route, she inexplicably ended up in the Rukongai, outside the Shin'ō District.
Then she encountered another monster, colder and more ruthless than anyone else, yet more passionate than anyone else, whose flames, when wielding his blade, could incinerate everything.
She fought with such gusto for the first time in her life, but also suffered her first crushing defeat, losing her left eye in the process.
Genryūsai Shigekuni Yamamoto did not kill her, seemingly understanding her desire to die from the clash of blades.
"It would be too boring to die like this. I need manpower, so you will sacrifice your life on the battlefield I have prepared."
He was a man who talked to himself, but Saitō Furofushi, was moved and chose to join his ranks, heading to the promised place of death, the Shin'ō District.
Deeply aware of the chaos of the time, Genryūsai Shigekuni Yamamoto wanted to bring the nobles together to create a more perfect and peaceful organization. He even renamed the Shin'ō District as Seireitei and founded the Gotei 13, using the Gotei 13 as a name to act as an assassin group.
Simply put, anyone who doesn't want to join the Seireitei family will die.
Such actions naturally provoked discontent among the nobility, some of whom were accustomed to carving out their own territories and ruling as kings in their own little corner of the land.
So the nobles united and besieged the Seireitei.
The Gotei 13 defeated the first offensive to annihilate the Seireitei and sought to wipe out all opposing forces.
Unexpectedly, a nobleman colluded with Yhwach in the World of the Living, leading the Wandenreich to launch a surprise attack on the Shin'ō District.
This resulted in heavy losses for the nobles who supported the Shinigami, Genryūsai Shigekuni Yamamoto led his army back to reinforce them, beginning an unprecedented war.
At that time, the Quincy did not have Schrift, nor did they have Blut Vene or Blut Arterie.
However, the Sternritter were by no means weak. Their numerical advantage, combined with the Quincy's archery attacks and the Ransōtengai, made them extremely difficult to kill.
Saitō Furofushi and didn't even know how he died; all he knew was that blood flowed like a river, and he couldn't see a single person around him.
Then, she was inexplicably sent to Hell by Konsō ritual.
Furofushi, a slogan used to mock others, has become a reality.
" Saitō Furofushi; I can grant you the death you desire."
Aizen extended his hand and said gently, "Come with me."
"Huh?" Saitō Furofushi, raised an eyebrow, looking at his intact chest with a provocative smile. "You think I'd believe that?"
"Whether you believe it or not, you don't need to make a judgment right now. Just follow behind me and watch carefully, and you will understand what you can believe and what you cannot believe."
Aizen's words were incredibly persuasive. His hand, without anyone noticing, had already covered Saitō Furofushi face, gently stroking the liquid-like chains. "Come with me."
Saitō Furofushi, heard a voice as soft as the wind in her ears. Through the Hell Butterfly, she could see Aizen's actions and knew that this guy was not someone to be trifled with.
When we actually met, I realized I had underestimated him.
The undetectable speed, the sensation felt only when the hand touched the cheek—all these elements deeply revealed the man's terrifying nature.
First he throws out his dreams, then he displays his abilities—does that mean he's qualified to achieve that?
"Hehe, interesting. Let me see your performance."
Saitō Furofushi, wanted to steal the peaches like a monkey.
Aizen skillfully dodged the question and laughed, "Of the Original Gotei 13 First Division Genryūsai Shigekuni Yamamoto and the 11th Division Retsu Unohana, the remaining eleven have all arrived at this Hell."
I want to subdue them one by one, Saito. I hope you can help persuade them.
"No chance." Saitō Furofushi, shrugged. "Our relationship was already terrible. With Yamamoto keeping things in check, it wasn't a problem. But once we get to Hell, we'll fight to the death."
They won't listen to my advice; if you want to subdue them, you'll have to rely on your own efforts.
"At least tell me some information, such as what kind of personality Katori Batsu'unsai has."
Aizen asked the question.
Saito Immortal blinked, thinking of the big-breasted woman wearing glasses and looking very cute, and wondered, "You have my information, why don't you know her?"
"There is very little information about the first Eighth Division. Even his death is shrouded in mystery. It's highly likely that he did something later and was eliminated by Genryūsai Shigekuni Yamamoto."
Aizen wanted to make a sarcastic remark, but then he thought about it and realized that after destroying Soul Society and creating Divine Realm, he had also concealed a lot of history and things. So he refrained from using his sharp tongue, lest he insult himself as well.
"Haha." Saitō Furofushi laughed heartily, "Is that so? So that's how that guy died. No wonder. She was always extremely loyal to Genryūsai Shigekuni Yamamoto and wouldn't tolerate anyone telling her anything. She seemed very dissatisfied with obeying the Central 46 Chambers."
He was definitely a rebel against the Central 46 Chambers, and then he was killed by Genryūsai Shigekuni Yamamoto. Haha, killed by the person he admired, what kind of expression would that guy have?
The word "worshipper" triggered Aizen's memories. He recalled the scene he saw through the Hell Butterfly: Momo Hinamori in the crowd was smiling happily, just like when she was by his side back then.
Time may smooth over many things, but some memories will never be erased.
Aizen lowered his eyes, deciding to eliminate that weakness, and began to think about how to persuade Katori Batsu'unsai.
That person actually built a Happy Town in Hell, bringing together a group of lonely jailers, thus making it the only place in Hell where people could laugh.
To win her over, force is definitely not an option; only strategy will suffice.
"Hey, even if you integrate Hell, how are you going to open the Gates of Hell from within?"
Saitō Furofushi, spoke.
Aizen snapped out of his daze, a smile appearing on his face. "Leaving through the Gates of Hell is no easy task. The Gates of Hell, formed from the Reishi the Five Great Noble Clans progenitors, are undoubtedly an extremely powerful barrier, having become one with Hell."
"Therefore, we must bypass the Gates of Hell and enter the outside world through the Mouth of Hell."
Five years ago, Aizen specifically studied the conditions of Hell.
At the time, Aura Michibane and Loly were his assistants, researching how to open the Gates of Hell, and unexpectedly discovered the existence of the Mouth of Hell.
The Mouth of Hell is easier to open than a door; any shift in the balance can lead to unexpected consequences.
That shift in balance required him to develop a Reiatsu amplification device, combining the Reiatsu of the Original Gotei 13 and his own, to amplify it, thus tilting the Gates of Hell towards the Soul Society and the World of the Living.
When internal and external forces are not equal, the balance will begin to collapse.
Even the slightest breakdown could be exploited by Aura Michibane and Loly, making his return to Soul Society a real possibility.
"This is my plan."
"Oh, then how shall I die?" Saitō Furofushi, asked in bewilderment.
Aizen laughed, "There is one in this world who can completely annihilate even the spiritual particles of a Shinigami."
"Oh! The second-generation Captain-Commander."
Saitō Furofushi, suddenly felt a glimmer of hope stir in his otherwise lifeless heart.
