Blending his human experiences with a request for time off, Fiander has spent several years in the human realm.
In addition to considering his future path, he dedicated considerable time to studying the essence of the soul and seeking to understand the laws governing this universe.
It's well-known that every world has its ways to harness these laws, but since his arrival in the Bleach realm, one significant issue Fiander has encountered is that, regardless of his training, improvements are limited to his physical abilities and Reiatsu.
Indeed, with some inherent talent and power, these aspects will yield results over time; however, certain skills, such as mastering the flames, seem elusive even after endless hours of effort.
Yamamoto Genryūsai's Ryūjin Jakka stands as the most formidable. The question arises as to why his flame manipulation is unparalleled, while others falter—simply due to the absence of a Zanpakutō akin to Ryūjin Jakka's?
Then, what was the reasoning behind the existence of two Hyōrinmaru in the later film adaptation, when another individual appeared to breach a significant taboo, prompting attempts at their eradication by the entirety of the Soul Society?
Initially, he intended to wait for the narrative to unfold before stealthily infiltrating the Soul Society, but the unpredictability of such plans left him feeling somewhat uneasy.
Consequently, while Aizen was orchestrating the selection of the "Espada," he discreetly penetrated the Soul Society and ultimately uncovered fragments of this world's origins in the halls of the Great Spirit Book alongside the so-called family seals of the four noble clans.
Long ago, this realm existed in a state of chaos. During that time, humans, spirits, and hollows co-habited, giving rise to the Soul King prior to the establishment of the three realms: Soul Society, the human world, and Hueco Mundo.
At that moment, distinctions between life and death were nonexistent, and the universe maintained a relative equilibrium. However, one day a hollow began its relentless consumption of human souls, and if unchecked, this hollow's continued feeding would culminate in the devouring of countless souls, ultimately transforming into a colossal Menos Grande, disrupting the world's balance irrevocably.
Thus, a formidable alliance formed, uniting the strengths of Shinigami, Quincy, Hollow, and Fullbring, which is what resulted in the Spirit King we now confine.
This god-like Spirit King vanquished the hollows on behalf of humanity, restoring harmony to the world. Throughout the process of eradication, some individuals discovered ways to eliminate hollows similar to the methods employed by the Spirit King.
These individuals are known as the five eminent nobles in subsequent generations. In essence, the Soul Society is recognized as the realm of spirits.
This includes one monarch and four nobles, excluding the Shiba family that has been erased.
The foundation of the Soul Society exists to cater to these so-called nobles and their king, yet its inception, along with the current world and Hueco Mundo, is rooted in a disgraceful past.
This past is the reason Fiander opted to reveal everything to Aizen at this moment. During this historical period, the five nobles harbored fears regarding the might of the Spirit King.
Some individuals are apprehensive that the Spirit King might treat them similarly to how he dealt with hollows in the future.
The mindset simply requires reassurance. In summary, despite having distinct agendas, the five nobles collaborated to imprison the Spirit King, encasing him in a massive crystal, and channeled his power to create the current Three Realms.
However, they later grew concerned about potential resistance from the Spirit King, leading them to sever his limbs and extract his internal organs, resulting in the current state of the so-called human-pig Spirit King trapped within the crystal.
It is challenging to envision the arrogant Aizen maintaining deference towards the Soul Society upon uncovering the truth, yet Fiander perceives a broader perspective.
Ultimately, their worldviews diverge significantly. From Fiander's stance, the Spirit King did not retaliate against the five nobles, as if he had foreseen the future.
In other words, the existing world aligns perfectly with what the Spirit King anticipated.
Even though the Spirit King is unable to speak or act, every soul across the three realms is interconnected with him. It's hard not to ponder that this may indeed be the Spirit King's intention.
The ultimate origin of all beings, be they Shinigami, Hollows, humans, or Quincies, emanates from the body of the Soul King. In this era, Urahara Kisuke, aware of the underlying truths, opted to sustain the current state of affairs for the Soul Society's stability.
Aizen's desire is to dismantle the confines surrounding him, a process that will undoubtedly demand countless lives, for he seeks to rebel against the Creator of this realm.
"Master Aizen, I have infiltrated the Soul Society and acquired certain knowledge. "
The moment Fiander concluded his statement, Aizen's demeanor remained unchanged, yet Ichimaru Gin and Tousen Kaname positioned their hands on their Zanpakutō beside him.
As a member of the "Espada," it is acceptable to venture into the present world in secrecy. However, now, without Aizen's directive, daring to penetrate the Soul Society covertly poses significant risks. If other Shinigami were to discover this, the repercussions are easily imaginable.
"Don't be anxious, Gin, Tousen. " "What do you mean by knowing things? "
Aizen wore a faint smile at the edge of his lips, clearly anticipating Fiander's response.
"I apologize for taking the liberty, but I secretly donned a Shinigami outfit and ventured into the Great Spirit Book Corridor of Soul Society. "
"I fully grasp the reality of this world. I. . . "
Just as Fiander was about to elaborate, Aizen cut him off.
"Alright, that's sufficient. I already possess the information I sought, and I'm pleased you shared the truth with me."
"Let's conclude here, Fiander. Unleash the Bakudō. "
"Certainly! Master Aizen! " As Fiander lifted his finger, the golden barrier in the hall swiftly transformed into spiritual particles and vanished into the air.
Aizen approached Fiander, giving him a pat on the shoulder and remarked,
"You must have reached that level! " Although the two behind him looked puzzled, they were unaware of the nature of their ruse.
"It's challenging, but I have a small insight! " Fiander contemplated for a moment before speaking slowly. The corners of Aizen's mouth lifted slightly, forming a lovely arc, while a glint appeared in his dark eyes.
"Perhaps you could be involved in that experiment! " Before Fiander could respond, Tousen Kaname beside him quickly interjected, "Master Aizen, he is merely an Arrancar; that type of experiment. . . "
"It's fine. Fiander is distinct from other Arrancars. Please regard him as a true ally from now on! "
"You will provide me with the answers I seek, correct? Fiander? "
Even though he was unaware of the specifics regarding the experiment discussed by Aizen and Tousen Kaname, he still bowed and affirmed,
"Yes! Master Aizen! "
While he might have previously felt uncertain and apprehensive about what lay ahead, the present Fiander was resolved to take charge and achieve his desires.
The path ahead is tough, yet I must proceed steadfastly. There is no option; I can't conceal myself, and eventually, trouble will find me.
In that moment, Fiander's expression was resolute, and his once stagnant heart surged with life, akin to arriving in a wondrous realm in a past existence, rediscovering his purpose and ambition.
