Chapter 1: The Enigmatic Attribute-Picking System

In a state of drowsiness, Katsuki slowly pried open his eyes, only to find himself surrounded by an unfamiliar setting. The towering skyscrapers that had once dominated his view had mysteriously vanished, replaced by the distinct architecture of traditional Japanese buildings.

Puzzled and disoriented, he embarked on a stroll through this surreal landscape. Every corner seemed foreign to him, and even his own reflection in a nearby window felt like that of a stranger. It didn't take long for him to piece together the extraordinary circumstances.

"Could it be...transmigration?" Katsuki mused aloud, realizing that he had likely crossed over into another world, although this one held an oddly familiar air.

Just as he grappled with the bewildering situation, an unexpected mechanical voice pierced the air.

[Ding! Host gained +0.1 Strength]

[Ding! Host gained +0.1 Strength]

[Ding! Host gained +0.1 Strength]

Katsuki was left dumbfounded as the mechanical voice continued its relentless announcements.

"What in the world is happening?" He scanned his surroundings, spotting two brawlers nearby. With each punch they exchanged, peculiar orbs of light tumbled from their bodies, accompanied by that same mechanical voice.

Perplexed, Katsuki couldn't help but wonder about the nature of this bizarre occurrence.

"What's the meaning behind all of this?" His curiosity deepened as he watched the two thugs grapple, the mechanical voice persistently chiming in.

[Ding!]

[Congratulations, host, you have successfully bounded with the Ultimate Attribute-Picking System!]

Even as Katsuki remained thoroughly flabbergasted, the mechanical voice shed some light on the situation.

"A system? So, crossing over comes with unique advantages?" Katsuki maintained his composure, but inwardly, he marveled at the apparent benefits.

Nevertheless, this "Ultimate Attribute-Picking System" piqued his interest and raised several questions.

"System, how exactly does this attribute picking function? Do I only have to spectate fights?" Katsuki's gaze remained fixed on the two brawlers in the distance, keen to grasp the intricacies of this newfound power.

[Ultimate Attribute-Picking System]

[This system enables the host to assimilate attributes dropped by others, thus enhancing the host's strength.]

[With a stroke of luck, one can acquire extraordinary attributes.]

The system promptly declared.

"Wow, simply collecting attributes makes me stronger? This feature is remarkably convenient!" Katsuki couldn't contain his excitement, recognizing that this "golden finger" of his rendered leveling up effortless.

"System, after accumulating attributes for some time, how much strength have I gained?" He inquired with curiosity. Although each increment appeared small, the notifications had chimed countless times, suggesting a considerable boost in his strength.

In the ensuing moment, a distinctive panel materialized.

[Host]: Homura Katsuki

[Strength]: 8.8

[Agility]: 3

[Spirit]: 10

[Abilities]: None

Upon scrutinizing the attributes panel, Katsuki swiftly deduced the underlying mechanics.

"System, originally, the base values for strength and agility were both three, correct?" He ventured a guess.

[Indeed. From the inception until now, your strength has grown by 5.8 points.] The system confirmed his hypothesis.

"No wonder I feel considerably stronger," Katsuki nodded contemplatively.

Typically, a person began with a strength value of three. In a brief span, he had nearly tripled his strength by consistently collecting attributes. Such a growth rate was nothing short of astonishing.

"By the way, what's the significance of this 'spirit' value? What's the typical base value for ordinary individuals?" He inquired, revealing his intrigue.

[For the average person, the base spirit value is merely 1. As a transmigrator, you possess a spirit value ten times greater.] The system meticulously clarified.

"Starting with ten times the spirit value? That's quite impressive," Katsuki acknowledged with satisfaction.

[In addition to the attributes already displayed on the panel, the host can acquire other unique attributes, although they will only manifest when encountered,] the system teased, leaving him eager to explore these hidden capabilities.

"Other attributes?" Katsuki's eyes gleamed with anticipation. Yet, a critical matter remained unresolved - he had yet to discern the world in which he found himself!

"System, to which world have I transmigrated to?" He scratched his head, unable to fathom the answer.

[You have entered the world of Bleach!] The system replied without hesitation.

"What? I've crossed over into the Bleach universe?" As an ardent fan, Katsuki's excitement was palpable. Bleach meant Hollows, Gotei 13, Espadas, Quincy... It was a realm teeming with intrigue and exhilaration. He had never dared to dream of such an opportunity.

"So, this is Karakura Town, isn't it?"

[Indeed!]

"Of course, it makes perfect sense; this is where the canon originates," Katsuki finally grasped why everything had seemed so eerily familiar from the outset.

"But I wonder, what era is this? Kurosaki Ichigo shouldn't have been born yet, right?" Surveying his surroundings, he noted the absence of skyscrapers, signifying that this era differed significantly from the original storyline.

"System, if I encounter Shinigami and Hollows, can I acquire their attributes?" Katsuki's attention honed in on the central issue.

In the world of Bleach, Reiatsu held paramount importance. Whether facing Shinigami or Hollows, battles invariably revolved around the clash of spiritual pressure.

For a moment, the system remained silent before delivering its response.

[You can not only collect Reiatsu but also acquire Kidō and even Zanpakutō abilities.]

This revelation instantly ignited Katsuki's enthusiasm.

"Truly? Even Zanpakutō abilities? How does that work?" A daring idea began to form within him; perhaps, just perhaps, he could someday acquire "Ryūjin Jakka."

[Your aspiration is ambitious, yet entirely feasible,] the system encouraged.

"Alright! I'm going to give it my all and gather attributes, with my sights set on Ryūjin Jakka!" He set a modest goal for himself. Even if acquiring "Ryūjin Jakka" proved elusive, he would happily settle for "Sakanade" or "Hyōrinmaru."

As he indulged in these daydreams, he remained oblivious to a spatial rift materializing behind the two brawlers.
