Hinome Hyuga and Hikari's Observation

Meanwhile, the room was filled with anticipation, and the door opened once more to admit the workshop's official instructor, accompanied by her assistants.

The instructor, a well-respected figure with an air of authority and deep knowledge of medical ninjutsu, stepped forward confidently.

Her assistants, equally proficient, followed closely, wheeling in several carts. On these carts were human-like dolls, meticulously designed for medical practice, each equipped to simulate various internal injuries and conditions for practical application.

The room's atmosphere shifted towards a more intense focus as the instructor began to speak. She introduced herself briefly but moved quickly onto the essence of the workshop: the practical application of battlefield healing techniques.

As she outlined the day's objectives, her assistants distributed the practice dolls among the participants, ensuring each had the tools needed for hands-on learning.

The instructor explained the variety of internal problems that the participants would be working on. These ranged from internal bleeding and organ damage to more complex issues like chakra pathway disruptions. She emphasized the importance of precision, control, and quick decision-making, skills that were critical for effective healing on the battlefield.

As the explanations transitioned into practical demonstrations, everyone in the room activated their Byakugan. The distinctive veins around their eyes bulged as they concentrated, their gazes penetrating the practice dolls in front of them.

The Byakugan's unique ability to see through objects allowed them to observe the simulated internal injuries, allowing them to apply their healing techniques more accurately.

The room was filled with quiet intensity as participants, guided by the instructor and her assistants, began to work on the dolls.

They practiced directing their chakra with precision to heal the simulated injuries, replicating the conditions they might face in an actual battle scenario.

The instructor moved among them, offering advice, correcting techniques, and occasionally demonstrating the correct way to address particularly tricky problems.

This hands-on session was not just about learning new techniques; it was an opportunity for everyone, including Hikari, to refine their skills, enhance their understanding of medical ninjutsu, and prepare themselves for the realities of healing under pressure.

The focused silence was occasionally broken by soft murmurs of discussion or the instructor's voice, but the prevailing atmosphere was one of deep concentration and the shared goal of mastering these life-saving skills.

As Hikari focused on his own exercise, practicing precise chakra control and application on the practice doll, his Byakugan inadvertently swept across the room. His gaze landed on the girl he had noticed earlier.

She was deeply engrossed in her task, her concentration palpable even from a distance. However, what caught Hikari's attention was not her focus but the extraordinary chakra concentration and exertion around her Byakugan.

'It is very unusual for someone of this age to have such a powerful Byakugan... No, it is rare for Side Branch members to open it at this age. I guess she is probably around 8 years old since it is basically unheard of for Side Branch members, even geniuses, to open it earlier, and her stature tells me that...',

'Interesting... It is no wonder she got into this class. But why medicine... Or is her Byakugan genetically somewhat predisposed to be good at medical matters outside of other fighting or auxiliary roles...?", Hikari analyzed silently, his curiosity piqued.

Meanwhile, the session moved forward, with the participants deeply engrossed in their tasks. The room was filled with a concentrated silence, broken only by the occasional instructor or assistant guidance.

Hikari and others practiced various healing techniques on the human-like dolls. Each simulated injury provided a new challenge and learning opportunity.

As the exercises became more complex, Hikari's proficiency and understanding deepened, and his Byakugan helped him visualize and address the internal issues with precision.

The girl, too, seemed to excel in her exercises, her focus unwavering as she skillfully maneuvered her chakra to heal the simulated injuries.

Her evident talent and dedication did not go unnoticed by the instructor, who praised and encouraged her, further highlighting her exceptional abilities.

As the session neared its end, the participants began to wrap up their final exercises. The instructor gathered everyone for a closing discussion, summarizing the day's lessons and emphasizing the importance of continuous practice and study.

She congratulated the group on their hard work and progress, encouraging them to apply what they had learned in real-world scenarios and to never stop seeking knowledge and improvement in their medical ninjutsu skills.

As the day's lessons wrapped up and the crowd began to filter out of the room, Hikari, amidst planning his departure, subtly caught a fleeting glance from the girl once again.

As participants dispersed, many heading towards additional classes offered within the expansive confines of the Hyuga Medical Research Institute, Hikari noticed the girl preparing to join another lesson.

Motivated by an inexplicable urge, he opted to secretly follow her progress from a distance instead of heading home.

Positioned on a terrace near her next class, Hikari couldn't fully understand why he felt compelled to observe her further.

His deep interest in the Byakugan's varied potential abilities—his drive to comprehend his Kekkei Genkai more intimately—seemed to guide his actions.

The girls' next session was notably more advanced than their earlier workshop. It delves into the management of serious injuries and conditions requiring long-term care.

His intrigue didn't end with that class. Hikari discovered she was enrolled in yet another, even more advanced session.

This course covered advanced Byakugan diagnostics, scientific research and development, and pharmacological mastery, areas that demanded a high level of expertise and understanding.

Shocked by her participation in such a sophisticated class, Hikari moved closer, drawn by a desire to witness her performance firsthand.

From his closer vantage point, Hikari could see the girl's Byakugan in action, its performance unwavering even after hours of intense use. This observation left him increasingly impressed.

Her ability to maintain such a strong and effective use of her Byakugan, especially across varied and advanced medical fields, spoke volumes about her talent and dedication.

After the final, the most advanced lesson concluded, and the participants began to disperse, including the girl who had remained oblivious to Hikari's observation the entire time. Hikari made his move.

The day had taken its toll on her, evident in her sore eyes and visible mental fatigue, yet she had remained dedicated throughout.

As the room emptied, save for the instructors and the head professor handling the session's aftermath, Hikari slid the door open and stepped inside like it was the most natural thing in the world.
