In the quietest hours of dawn, as the first rays of sunlight began to break over the horizon, Hinome Hyuga, a graceful 17-year-old with elegance befitting her current status, stirred from her sleep. Inside her striking room within the grand Third Estate of the Hyuga clan, she sat up effortlessly.
Thanks to a recent scientific procedure she had undertaken on herself, Hinome found her vitality steadily increasing and her need for rest diminishing by the day.
Even with minimal sleep, she felt refreshed, as though her body was adapting to some newfound increasing vitality coursing through her veins.
Deciding not to linger in her chambers, she rose from her bed and dressed with deliberate care, her movements fluid and purposeful.
Her own residence latched directly to Hikari's now mostly empty main residence, barring some servants of the Third Estate, meticulously designed by Hikari Hyuga himself to accommodate her personal needs, catering not only to her training and life but also to her scientific pursuits.
Seeking clarity and focus for the day ahead, Hinome stepped into the estate's grand courtyard. The cool morning breeze caressed her skin as she stood still for a moment, gazing at the gradually brightening sky.
There was peace in this moment, yet something beneath the surface nagged at her—a subtle, unshakable unease. It was as though the air itself carried a warning, stirring a faint sense of foreboding within her.
Determined not to let this strange feeling disrupt her morning, she stretched and prepared for a session of light training.
Physical discipline always helped her center her thoughts before diving into the intricacies of her research later in the day.
Ever since the war began and Hikari departed, Hinome had not ceased her relentless pursuit of both training and research.
In fact, she had reached several pivotal breakthroughs in both areas—so much so that even she was uncertain of her current strength.
Her rigorous training, combined with the enhancements she had made to her body, placed her in uncharted territory.
Over time, as her skills in cellular manipulation and cultivation evolved, she began methodically introducing her own cultivated Yang Release cells back into her body.
Each reintroduction improved her physical capabilities and chakra reserves, systematically refining her in both body and spirit.
On the more traditional shinobi side, she had finally mastered the long-envisioned "Frost Release," an advanced elemental fusion she and Hikari had conceptualized together in their youth.
With this mastery, she now felt ready to unleash it in real combat, a testament to her dedication.
But her most profound achievement lay beyond elemental mastery. Her recent advancements were far more scientific, pushing the boundaries of cellular engineering beyond anything even Hikari had envisioned.
With Hikari absent, her initial genetic and advanced cellular research intensified. She was no longer satisfied with the earlier enhancements she had made to herself—there had to be more, a deeper truth hidden within her biology.
During one of these experiments, as she extracted cells from her body for cultivation, she made an unexpected and shocking discovery.
She had taken samples from her own Byakugan on a whim. What she observed left her perplexed and exhilarated.
Upon observation with her latest, most advanced instruments, the cells within her eyes were fundamentally different from those in any other part of her body.
They existed on a unique spectrum, distinct from all other tissue, no matter how refined her previous enhancements had been.
These ocular cells were unlike anything she had encountered before. They possessed an extraordinary, almost incomprehensible structure—intracellular organelles that were unlike any other; each one imbued with an enigmatic, potent chakra.
It was as if these cells carried the essence of something beyond mere biology, as though they were touched by creation itself, perhaps even divine in origin.
The more Hinome studied them, the more she became convinced that these cells held secrets far greater than she could comprehend at first glance.
Driven by a feverish curiosity, she devised a bold new experiment. Using her specialized instruments, she began isolating, cultivating, and attempting to replicate the Byakugan's unique cells externally.
It was an intricate, painstaking process that demanded months of observation and experimentation.
But as her knowledge and methods improved, she inched closer to what had initially seemed impossible—creating her own miniature Byakugan.
After nearly a year of tireless work, Hinome's breakthrough finally arrived. She realized, with both awe and exhilaration, that it was indeed possible to cultivate and recreate Byakugan cells into functioning miniature organs.
Her heart raced at the implications of what she had accomplished. The thirst for knowledge that had always driven her now surged to new heights, the possibilities unfolding before her like a boundless horizon.
Driven by both scientific curiosity and ambition for power, Hinome began creating numerous external Byakugan, testing and experimenting with them for research.
Yet, as she crafted more of these miniature functional Byakugan, a groundbreaking idea struck her: What if she could fuse these Byakugan somehow? Could she forge an even more powerful Byakugan—something purer and far stronger than the one she currently possessed, despite being one of the most talented members of the Hyuga clan?
However, merging the Byakugan proved to be far more challenging than she initially imagined. The process was shrouded in complexities beyond her current expertise. It required not only biological but also technological knowledge.
Uncertain where to begin, she contacted Hikari, sending him detailed letters over several months while he remained on the frontlines and was busy.
Initially, Hikari was skeptical of her ambitious ideas, but his skepticism soon gave way to inspiration. A few months ago, he devised a potential solution that reignited both their hopes.
Together, they began working on plans for a revolutionary scientific instrument capable of merging the Byakugan without sacrificing its functionality.
Hinome had no idea how Hikari acquired such advanced technical knowledge—it seemed far beyond anything she expected him to know—but she trusted his brilliance implicitly.
Their collaborative design outlined a machine that could exert precise pressure on the ocular cells, forcing them to fuse without compromising their original form or devolving into useless biological material.
Finally, about a month ago, the machine they had painstakingly designed was manufactured outside the village in secret and delivered to Hinome's compound within the Third Estate.
Using the machine was delicate work, as it needed to apply just the right amount of pressure to combine the Byakugan eyes without triggering cellular entropy.
It would both compress and stabilize the fused eyes, ensuring they remained functional Byakugan rather than degrading into mere tissue.
After days of preparation and countless adjustments, the moment of truth arrived. The machine worked. A week ago, the final product—a new, extraordinary pair of Byakugan—emerged.
But what stunned Hinome the most wasn't just that the fusion had succeeded—it was the transformation that followed.
The resulting eyes were unlike any other Byakugan she had ever seen. They retained the signature Hyuga white sclera, but their irises now shimmered with a minute but brilliant light-blue tint as if infused with some ethereal energy, marking them as something entirely new.
Hinome's pride swelled. This was the pinnacle of her scientific achievement. But beyond the personal satisfaction, what filled her with the most joy was the thought that these new eyes could help Hikari become stronger.
She believed with all her heart that gifting him these eyes would elevate his strength to unprecedented heights. Overflowing with excitement, she wrote to him immediately, eager to share her success.
To her surprise, Hikari responded not only with boundless praise but with an unexpected request: instead of giving the eyes to him, he urged Hinome to transplant them into herself.
He insisted he had other plans for him that didn't require the new Byakugan and that her abilities were far better suited to wielding them. Though surprised by his decision, Hinome trusted his judgment.
Reluctantly, she transplanted the fused Byakugan into herself a few days ago, and the healing process was now nearly 100% complete.
Nonetheless, during the entire process, Hinome confirmed something more peculiar after gradually acclimating to her newly enhanced Byakugan.
The dojutsu's power-up not only expanded her visual prowess but also profoundly affected her soul, physical capabilities, and chakra reserves.
It was as if the enhanced Byakugan had triggered a chain reaction within her entire being.
This realization finally validated a long-standing hypothesis of hers: that strengthening any one aspect—whether it be the soul, body, corresponding chakra produced through their energies, or dojutsu—would, in turn, lead to a balanced strengthening of all other aspects to a certain extent. It was as if there was an innate shinobi feedback loop that existed.
The connection was undeniable now. The power of the Byakugan was intrinsically tied to every core aspect of her existence, and each improvement had a holistic impact, enhancing her beyond just the visual scope.
Nevertheless, the entire operation remained a closely guarded secret between them. Hikari, ever-cautious, warned her not to leave the Third Estate or draw any attention to herself until he returned to the village 'pretty soon' after he finished his own training and was ready to defy the Hokage's Faction pressure for them to stay outside the village.
He was particularly concerned about the Patriarch and the other Main Branch elders noticing the change and questioning them.
With the clan's rigid traditions and scrutiny, Hikari didn't want to risk any confusion or unwanted attention before everything was in place on his return.
However, as Hinome continued her morning training, lost in thought and reflection, her expression suddenly shifted.
Her brow furrowed deeply, and her new Byakugan, with its faint bluish glow, sharpened toward the distant main gate of the Hyuga compound.
Instinctively, her vision extended further, scanning the vast expanse of their territory. What she saw sent a chill through her.
'Something's wrong…', She thought, her fists clenching as tension spread through her body.
Her enhanced vision picked up unusual activity at the periphery of the compound. A large number of shinobi were silently gathering, surrounding their estate like a tightening noose. The subtle chakra patterns forming at various points told her everything she needed to know.
'A barrier... They're setting up a barrier...', she also realized with growing alarm. Her heartbeat quickened, and the early morning peace she'd felt moments ago shattered.
'No… this isn't just a routine visit. This feels organized. Coordinated. An attack...', Hinome's hands balled into fists, her mind racing through the implications. The realization hit her hard: The Hokage faction was coming for them.
Her jaw tightened, and her pulse pounded in her ears. 'I'll have to fight too, won't I? There's probably no avoiding it…', She thought, her gaze flickering across the compound as she calculated their defenses.
'I think… other than the Patriarch, I'm the second strongest here now...', The weight of that truth settled heavily on her shoulders.
This would not be like her experiments in controlled environments, nor just another sparring session.
It was real now. Her new eyes tingled with anticipation as if aware of the imminent battle, adjusting to the faint disturbances in the air. Hinome exhaled slowly, her expression hardening. Whatever was coming, she would be ready.
