As Aizen in Naruto and Joined a Chat Group Chapter 1: Aizen Sosuke

Konohagakure Grand Arena.

Uchiha Shisui surveyed the vast expanse of the spectators, drawing in a deep breath.

This day marked his Jonin promotion examination, yet for Shisui, it was also the scene of a destined confrontation. His adversary was a prodigy who stood as his equal in both innate talent and unyielding determination—Aizen Sosuke.

They were famously known as the "Twin Stars of Konohagakure," a pair bound by rivalry and the deepest of friendships.

Clang.

The sword slid from its scabbard. Shisui's right hand registered a slight tremor on the hilt—not born of apprehension, but exhilaration. His gaze remained fixed on the boy with brown hair opposite him, whose countenance wore a serene smile.

"I comprehend, Aizen. You must be experiencing the very same emotions I am at this moment."

He understood Aizen implicitly, just as Aizen seemed to grasp him. Shisui felt their connection had ascended to a plane where mere glances sufficed to exchange thoughts.

This was the unwavering trust they had painstakingly cultivated through countless battles fought shoulder-to-shoulder on the treacherous Kirigakure front lines.

From the spectator stands—

Sarutobi Hiruzen observed the two youths poised for combat, the edges of his lips upturning subtly. "Who do you surmise will emerge victorious?"

"Hmph! Aizen is an individual I personally took under my tutelage!" Shimura Danzo, seated adjacent to him, retorted with frosty composure.

Though his old comrade's tone remained as rigid as ever, Sarutobi detected the distinct undertones of pride and contentment within his words. He couldn't resist a gentle barb, "However, if my memory serves me correctly, Sosuke never once addressed you as 'teacher,' did he?"

Danzo's expression flickered before he shot back, "He is affiliated with my Root division. Such feeble and misguided attachments, which you so cherish, are unnecessary for him. A ninja's existence is far removed from a child's fanciful games!"

Sarutobi paused, a sudden apprehension dawning that his old friend was steadily venturing down an increasingly perilous path. He felt compelled to interject. "Danzo, you—"

But before his sentence could conclude, Danzo cut him off. "It commences now, Hiruzen. Maintain your focus and witness firsthand the flawless execution of my creation!"

A subtle, resonant hum filled the air.

Aizen deliberately withdrew his blade from its resting place at his hip. "Disintegrate, Kyoka Suigetsu."

A sharp sound, akin to fracturing glass, reverberated throughout the arena. From Aizen's position, delicate tendrils of mist began to unfurl, rapidly enveloping the combat stage. They swirled and coalesced, shrouding the area in an ethereal haze.

So, he intends to initiate the engagement with that particular ability.

Shisui maintained an impassive countenance. Within his blood-red eyes, three obsidian tomoe spun with rapid intensity.

Kyoka Suigetsu!

As Aizen's most intimate comrade, Shisui possessed intimate knowledge of this technique—it was Aizen's unique, S-rank Genjutsu.

This formidable illusion employed the play of light upon the blade to conjure mist and cascading water, thus disorienting the opponent's visual perception and ensnaring them within a phantasmal realm. Furthermore, it served to mask Aizen's presence, enabling him to approach undetected.

Precisely as he is doing now!

Shisui abruptly pivoted, his short sword grasped firmly in hand, and executed a swift, horizontal sweep.

Clang!

The clash of their respective blades sent a shower of sparks raining down. Aizen skillfully retracted his weapon after the parry. Shisui, however, seized the momentary advantage without hesitation, pressing his attack.

Their extraordinary agility rendered them mere flickers, shadows darting across the arena floor, their paths crossing and their weapons meeting in a relentless exchange.

The assembled spectators were utterly captivated by the fierce combat unfolding before them, their gazes riveted to the intense duel.

At this precise juncture—

No one, not even the esteemed Sarutobi Hiruzen and Shimura Danzo observing from their elevated platform, perceived the presence of a young man standing at the fringe of the spectator area. He was clad in a simple white kimono, his hands concealed within his sleeves, observing the ongoing match with an expression of profound tranquility.

His brown hair was slightly disheveled, and he sported a pair of dark-rimmed spectacles. A long sword, distinguished by its green hilt, was secured at his waist. His features betrayed no hint of emotion, neither joy nor sorrow—only an unwavering neutrality.

Should any onlooker in the throng happen to cast their gaze in his direction, they would be struck with astonishment upon realizing—his visage was an exact replica of Aizen Sosuke, the combatant presently engaged in the arena.

Yet, no one took notice.

Even if an individual did happen to glance his way, their eyes would perceive nothing more than an unoccupied passageway. His presence would remain entirely unseen.

This was the genuine potency of Kyoka Suigetsu—absolute, compelling hypnosis.

This was not merely a Genjutsu; it was the inherent capability of Aizen's Zanpakuto. The instant he unsheathed his blade earlier, every soul within the arena had already succumbed to the pervasive influence of Kyoka Suigetsu.

Even the esteemed Sharingan, typically adept at discerning and dispelling illusions, found itself powerless against its overwhelming might.

Anzen had established this irrefutable fact a considerable time ago.

Yes, to be precise—

The young man with the brown hair bore the name Anzen. He was not, in fact, Aizen.

Having originated from Earth, Anzen had established a reputation as a preeminent psychological analyst in China, dedicating his expertise to the study of the mental landscapes of particularly unique individuals.

His transmigration to this reality was devoid of any dramatic incident. He neither met his end via vehicular collision, was struck by lightning, nor was he inexplicably drawn into a subterranean sewer system. He simply drifted into sleep one evening, only to awaken in the world of Naruto.

Not only had his form transformed into that of a young child, but he had also been granted a unique capability known as the "God-Level Character System."

The system operated on a straightforward principle, essentially functioning like a lottery.

It housed characters from an infinite array of worlds, permitting the user to obtain one through random selection.

Anzen's inaugural draw yielded a character role-playing card for Aizen. By embodying the persona of Aizen effectively and enhancing his proficiency, he could progressively unlock all of Aizen's inherent abilities.

Naturally—

While seemingly uncomplicated, the act of role-playing presented its own set of challenges.

He was obligated to flawlessly mimic Aizen's disposition, inclinations, habits, vocalizations—down to the minutest detail.

Fortunately, the system proved remarkably accommodating, automatically modifying his physical form to ensure an exact likeness to Aizen.

Moreover, the system had seamlessly integrated all of Aizen's recollections and aptitudes into him. Absent these transfers, his journey over the ensuing years would likely have been far less advanced.

Drawing his focus back to the present moment, Anzen observed the progress indicator on his system's interface.

Current Role-Playing Progress: 34%

Buzz.

The atmosphere abruptly shimmered, warping as if a vortex had formed. A figure clad in a black cloak, concealed by an unusual mask, materialized directly behind him.
