Chapter 10: The Yuki Clan in the Warring States period.

****

As Tatsuya grew older, he strengthened his ties to the Yuki Clan. He had always been a beloved figure, admired for his prodigious talent and quiet wisdom. However, by the age of 10, Tatsuya's relationship with the clan had changed, from that of the talented son of the clan leader to that of an influential voice within the clan. The boy who had mastered incredible powers now found himself in a leadership role.

The structure of the Yuki Clan was traditional and simple, focused on preserving their ice techniques and surviving the endless wars of the Warring States period. However, Tatsuya saw greater potential for the clan and began proposing ideas to transform it from a mere fighting force into a powerful, self-sustaining entity.

The first of Tatsuya's gifts to the clan was the Rokushiki martial arts techniques that were once exclusive to Kuzan and the elite of the One Piece world. His father, Yuki Kaito, a formidable leader, saw the value of these new techniques almost immediately. Tatsuya spent countless hours teaching his father and the other elites of the clan how to use the powerful techniques of Soru (blinding speed), Geppo (air walk), and Tekkai (iron body).

The clan members trained rigorously to master these techniques, transforming the Yuki clan's reputation from a group of shinobi known only for their ice release technique into a much more versatile and dangerous force. The elders, though initially skeptical of these foreign techniques, had come to realize their significance. Tatsuya's training helped the clan become much more adept at close-quarters combat, improving their mobility on the battlefield with Geppo and allowing them to match and defeat rival ninja clans that had once underestimated them. While they could not learn Haki, as it was not a power related to the Naruto's world, the techniques passed down from Tatsuya made the Yuki clan more deadly and versatile on the battlefield. Combined with the clan's mastery of long-range attacks through their Ice Release techniques, the Yuki clan became a formidable multi-range fighting force, feared by other factions during the Warring States period.

The Warring States period had thrown the country into chaos, with daimyos and factions engaged in constant battles. All vying for control. Mercenary ninja were in high demand, hired for espionage, assassination, and infiltration. In the midst of the turmoil, the Yuki clan remained neutral, focusing on survival. Because they were a fierce shinobi clan with their Ice Release abilities, they were often recruited by powerful lords. Since Tatsuya was the son of the clan's leader and was still young, he was not sent to the battlefield. He was seen as someone with great potential and the next patriarch of the clan. They believed that he was a child capable of causing the rise or destruction of a clan. That was why his parents and the clan elders did not want to expose his incomparable genius to the world yet. They wanted to give him time to grow.

As the conflict intensified, Tatsuya knew that one day he would have to unleash the full potential of his gifts. For now, he continued to train, working carefully to unlock the last seals of his power. His mastery of Haki and Rokushiki increased by the day, and his ice abilities had already exceeded his clan's expectations.

Yet, deep down, he knew that much of his knowledge, powers, and memories remained sealed, waiting for the right moment to fully emerge. That moment would come soon.
