Back then, Zero did harbor some resentment towards Aizen, who repeatedly plotted against him; however, it seems that those were secondary issues now. When his true form emerges as the Soul King, he will be able to resolve all grudges.
Aizen had Inaba Kage lead the group to see the methods for increasing power. Ginjo and Tsukishima were eager to try, while Jackie remained quite calm.
Ryūsaki's heart skipped a beat: No way? It can't be that kind of method, can it?
Upon arriving at the Laboratory, just as Ryūsaki had predicted, the method was indeed Hollowfication!
"Hollowfication? Humans and Hollows merging into one? How is that possible? A person's will would probably be completely devoured by the Hollows." Jackie immediately raised her doubts.
"Impossible? Ginjo, your companions are so ignorant! Haven't you ever shown your Bankai to them?" Inaba Kage asked Ginjo with a smile.
Ginjo pondered for a moment, "Jackie, do you remember what I said when I taught you how to use power? We humans who possess power were all attacked by Hollows before we were born, so we have Hollow power within us."
"Basically, our power comes from Hollows. After I Bankai, the power of Hollows is amplified, and I can even use Menos Grande, which only Cero can use..."
Inaba Kage chimed in, "That's right. Human souls and Soul Society souls can coexist with Hollows, breaking their original soul state and making the symbiote exceptionally powerful."
"Among the Gotei 13: Captains 5, 9, and 10 all possess the initial ability to Hollowfication, making them very powerful in combat."
Ginjo narrowed his eyes slightly and said in a deep voice, "Preliminary Hollowfication?"
"That's right, it's only a preliminary form of Hollowfication. Your Bankai form is also considered a preliminary Hollowfication. There are deeper Hollowfication and complete Hollowfication later on. Currently, only Tōsen can achieve complete Hollowfication..."
"It's not nice to talk about others like that, Inaba Kage!"
Inaba Kage mentioned Tōsen, Tōsen appeared behind everyone; he was the main person in charge of Hollowfication.
"Then you explain it yourself! After all, you're the expert on Hollowfication." Inaba Kage smiled, handing over the task of introducing the newcomer to Tōsen.
"Hollowfication? What a terrible term! Internally, we've always called it 'evolution,' not Hollowfication."
"Alright, you introduce your Evolution Army yourself! I'm going to go study my invading army now."
Tōsen slightly annoyed corrected Inaba Kage, but seeing that he didn't object, he continued leading the group on the tour and explaining:
"I was able to completely Hollowfication because I was killed. As Captain-level, my Reiatsu was extremely high, so even after death, I didn't automatically decompose into Reishi."
"Lord Aizen had no choice but to inject a Hollow into my body to revive me. This proves that even Captain-level officer with a complete body can be Resurrection shortly after death..."
Ginjo exclaimed in surprise, "To be able to Resurrection from death using a void? How is that possible?"
His mind was racing; perhaps Kitahara could be Resurrection? At the time, he saw that Kitahara had only been dissected and that there was still a possibility of recovery.
"You don't need to overthink it. This is only possible with the immense Reiatsu of Captain-level, and even then, they must have just recently died!"
Tōsen seemed to have seen through Ginjo's thoughts, and her words left Ginjo looking dejected.
"If Captain-level don't automatically decompose into Reishi, then by taking the corpses of deceased Captains and injecting them into the void, wouldn't that create an army?"
Tsukishima noticed his boss's displeasure and quickly changed the subject, also expressing his own curiosity.
Zero in Ryūsaki's Inner World laughed and scolded him for his ignorance. Those Captains' corpses were dangerous things; they should have been cremated long ago. Why hold all sorts of festivals and send their souls to Hell?
Back when he was Captain in the Seireitei also died in battle. His subordinates were sent to the World of the Living to capture Hollow Priests, and it was then that he learned of this.
Tōsen's reply was similar to what Zero had told Ryūsaki in his Inner World. Ginjo and the others finally learned that some of the powerful Togabito in Hell were former Court Guard Squads.
Tōsen began explaining the precautions to take after injecting Hollows. He advised against injecting Hollows captured from Hueco Mundo, suggesting instead that they inject Hollows that had been cultivated.
Artificial Menos Grande are more powerful and easier to integrate and control.
To achieve a significant improvement, it would be necessary to inject Vasto Lorde-class artificial Menos Grande, and Hollows of that level are currently being cultivated in Hueco Mundo.
It's unknown how long it would take for a Vasto Lorde to be born naturally, which is why Aizen had the idea of breeding it; even with breeding, it would take more than ten years from start to finish to have one successful one.
The two low-level Vasto Lorde that were successfully cultivated some time ago were given to Tōsen, whose original Adjuchas- class Vastodes that had Resurrection him have been replaced. The other Vastode was given to a traitor within the Court Guard Squads.
Therefore, powerful fusion entities not only need to be selected from Hueco Mundo, but also need to wait.
Three artificial Vasto Lorde Menos Grande are currently being bred, with plans to successfully breed them within five years.
"I don't need to merge with the void."
"Why?"
"To us Pure-Blood Quincy, Hollows are evil forces. If I were to recklessly inject them, not only would my previous abilities be completely destroyed, but I might also be unable to suppress them and be forced to purify myself."
"Self-purification? Does that mean suicide?"
"Pretty much. Even if they don't die, they'll lose many advanced skills."
When Ryūsaki refused to Hollowfication, Ginjo was quite surprised. However, after hearing Ryūsaki's explanation, he gradually understood: Ryūsaki was unwilling to gamble on a possible power with the power she was certain of.
After Hueco Mundo's initial attack on the Soul King failed, Hueco Mundo fell into a period of peace...
Grimmjow and Ulquiorra travel together, searching for and devouring any unwanted prey they find to grow stronger. They keep to themselves and avoid conflict with the group of Arrancar led by Nel and Tier Harribel.
These two groups are basically the largest forces in Hueco Mundo. At Nel's suggestion, they established the Hueco Mundo Council with the aim of jointly resisting the invasion of external forces and refraining from attacking the outside world until they have the strength...
Soon after, the peace of Hueco Mundo was shattered when a long-lost figure reappeared— Szayelaporro Granz, who wanted to turn Hueco Mundo into his own Laboratory.
If it were just Szayelaporro alone, either side could easily subdue him. With his increased strength, killing him in a two-on-one situation would be incredibly easy.
But then, two former companions reappeared by Szayelaporro's side—Coryat Starrk and Lilynette Gingerback!
Starrk and Lilynette were completely subservient to Szayelaporro. They remembered Grimmjow and his men, but seemed unable to refuse Szayelaporro's orders. They cooperated with Szayelaporro in instigating several power struggles.
The inhabitants of Hueco Mundo called it the 'War between the Hueco Mundo Council and the Rebirth Army' because Szayelaporro also had hundreds of Arrancar with him, Arrancar had disappeared after being severely wounded or killed.
They thought he had been swallowed up, but he was unexpectedly Resurrection by Szayelaporro...
Then, Aizen ordered Tōsen to come to Hueco Mundo to find materials. He knew that the Soul Reaper were monitoring the central area of Hueco Mundo, so he did not risk being exposed by forcibly subduing the Arrancar of the Hueco Mundo Council.
Later, when Tōsen encountered Szayelaporro in a remote area, he reached an alliance agreement with him...
Szayelaporro began providing Tōsen with various Hollows possessing strong evolutionary potential, allowing him to cultivate powerful individuals; while Tōsen, in turn, provided Szayelaporro with souls possessing Reiryoku from Soul Society.
Aizen's mole controlled a high-ranking noble family. With the noble family as a cover, sending dozens of awakened individuals every month was no problem at all.
In a rather luxurious private apartment in Karakura Town, Ryūsaki is chatting on her phone with her older brother.
"Gloves? I don't use them at all, and they don't suit me... By the way, what did you major in at university? Hmm, medicine... Okay, whatever you want!"
Five years passed in the blink of an eye. Ryūken went to university to study medicine, while Masaki Kurosaki, who was a Little Ichi than him, was still in high school.
According to Ryūken himself, he discovered that Masaki didn't seem to have any feelings for him; it was just the engagement that bound the two of them together.
"Me? I'll go back later! I'm busy right now, I'm in Karakura Town! Going back to high school? I'll think about it... um, that'll do for now..."
Next year, Ryūsaki will be going to high school, which is perfectly normal according to the trajectory of a normal person.
After hanging up with her brother Ryūken, Ryūsaki jumped off the balcony of her rented apartment and headed towards Xcution's Headquarters.
In recent years, Ryūsaki has only been able to visit the Ishida Family three or four times a year at most, and most of the time he contacts his family by phone... According to Sōken, the atmosphere in their home is at least better than the world inside the 'Sun Gate'.
Sōken had discussed some information about that world with the two brothers, but not much...
When Ryūsaki arrived, all the members were already there. They were there to witness Ginjo's Hollowfication process. Today, Ginjo was going to be the first person in Xcution to merge with a Hollow.
The small team led by Ginjo has gained two more members: one named Taze Kiriko and the other Aura Michibane. Both of them can Fullbring.
Taze Kiriko is a middle-aged man with one eye who joined Xcution because he needed something from Ginjo.
His so-called desire was nothing more than wanting to become stronger through Ginjo's help. After gaining a deeper understanding of the organization's goals, he fully agreed with the Hollowfication and seemed somewhat impatient.
Aura Michibane, a girl with black hair and black eyes, took her mother's surname after her father's death. Not wanting to be taken care of by her mother forever, she decided to live on her own.
From being a complete stranger in a strange land to being penniless, she eventually fell so low that she slept in a park and was attacked by a phantom. It was only after Ryūsaki encountered her that he invited her to join him.
This girl didn't have any particular favorites, and therefore didn't possess any Fullbring ability of her own. However, she had a strong learning ability; she could learn various combat styles in a matter of minutes and become proficient in just a few days...
"This is Hueco Mundo. Follow me and don't wander off. The guards here aren't very friendly." Emerging from the Garganta, Tōsen urged the others to stay close.
The fusion took place not in the New World, but in the 'Evolution Corps' under the jurisdiction of Tōsen, which was located in Hueco Mundo. Ryūsaki and the others had to go there together.
A crescent moon hangs motionless high in the sky, amidst an endless desert dotted only by Quartz Trees and a few rocky hills.
Ryūsaki had seen these things before in her memories, so they didn't find them particularly novel. Ginjo had also been here a couple of years ago, but this was the first time the others had seen them. They all felt the oppressive atmosphere of this world.
This building, transformed from a giant rock, served as Szayelaporro's Laboratory and residence, surrounded by his henchmen.
"What a desolate world! How do the Hollows live here?" Aura asked curiously, and the other members also showed expressions of interest.
"They eat their own kind. Hollows evolve by devouring their own kind, gain power, and ultimately regain their sanity."
"How cold-blooded and heartless!"
Ryūsaki's words startled the group, but they quickly understood. Their organization was also one that evolved by devouring its own kind, and everyone knew about Ginjo's Fullbring ability.
