System?!!

---

Akira sat on the roof, gazing at the moonlit sky, taking a swig from a bottle of wine. "Sixteen years..." he muttered to himself.

Akira was sitting alone recalling his past.

He hadn't always been a member of the Uchiha clan. Originally, Akira had been an ordinary human on the Earth, living a typical life, enjoying anime, reading manga, and novels like any other normal human at this time.

But one day, an accident caused him to reborn in the Ninja world (Naruto anime), where he was reborn as a baby in the Uchiha clan.

The excitement of living in the world of ninjas and being part of the powerful Uchiha clan was short-lived. His parents were sent to fight on the front lines of a war and of course were killed, leaving him an orphan. Akira quickly realized that this was a world filled with danger and uncertainty, where Only power mattered—the message every fan-fic, had shown.

So determined to survive, he began training at the age of one. Whether it was due to his background as a time traveler or sheer luck, his talent was extraordinary. When he learned of his parents' deaths, the pain triggered the awakening of his Sharingan—a feat that could cause an uproar, as a one-year-old child manifesting such power was unheard of. However, he kept this a secret, continuing to train in silence.

By the age of four, Akira had awakened the Mangekyō Sharingan. His abilities mirrored those of Uchiha Shisui's Kotoamatsukami—except his Mangekyō had another unique power: the ability to travel between different worlds. He discovered that each of his eyes could set a different world as an anchor point, allowing him to freely travel between them.

(A/N: Guess what he, a time traveler was cheating)

The first world he traveled to was the world of *Demon Slayer: Kimetsu no Yaiba*. There, he immersed himself in the unique Breathing Styles of the Demon Slayer Corps, mastering all the breathing techniques, including the powerful Sun Breathing, and using his Sharingan to copy the sword forms of every technique

. In time, he helped the Corps defeat Muzan Kibutsuji, the progenitor of demons, as a way of repaying them for all he had learned, making Muzan knell in fear in front of him.

Armed with newfound strength and swordsmanship, Akira returned to the ninja world, earning the moniker "Sword God" on the battlefield, a title as feared as the Fourth Hokage's "Yellow Flash."

He was having a bright future.

However, when Uchiha Obito attacked Konoha with the Nine-Tails, Akira was prevented by the Konoha leadership from participating, as they feared his power, making it clear they didn't have any trust in uchiha.

In the aftermath of the attack, rumors spread that Akira had been behind the Nine Tails' rampage, turning him from Konoha's hero to its scapegoat. Despite knowing the truth, the village's higher-ups did nothing to clear his name. Akira realized that Konoha would never fully trust or accept the Uchiha clan, and his disillusionment with the village grew.

Instead of dwelling on the betrayal, Akira continued his secret training, traveling to other worlds. One of the most recent worlds he discovered was *One Piece*. But before he could explore it in depth, the Uchiha clan's impending coup forced him to act.

From the very beginning, Akira had one goal: to save his family from that tragic night. He knew the darkness that loomed over the Uchiha clan, and the events that would lead to their downfall.

His first steps were to correct the perspectives of Shisui and Itachi, who were key figures in the clan's fate. At first, he thought it would be an impossible task, much like the struggles described in fanfics he had read.

But after speaking with them, Akira realized something surprising—both Shisui and Itachi had hearts so pure, it was almost foolish. "So pure it borders on stupidity," Akira thought. "No wonder they could trust someone like Danzo."

Seeing their innocence, Akira began to treat them as his own little brothers, guiding and protecting them. He made a solemn promise to them: he would save the Uchiha clan, but he would also try to avoid harming Konoha in the process. It was a delicate balance, but Akira believed in their future.

However, the tension with Konoha was undeniable. The growing distrust and looming threat of conflict made Akira realize that his clan needed more than just promises—they needed a safe place to thrive. With that in mind, he made the bold decision to lead the Uchiha clan to the One Piece world, where they would carve out a new home and destiny, away from the dangers of Konoha.

Akira was on a good mood.

Here, on Amazon Lily Island, he believed that the Uchiha clan could finally thrive without the oppression they faced in Konoha. This world was ripe with opportunity—perhaps they could even establish themselves as one of the Four Emperors.

As he considered the future, a sudden voice echoed in his mind:

[Ding! Host detected as an adult! The system is now activating.]

[Family Rejuvenation System successfully activated.]

[First mission triggered: Secure a new home for the Uchiha clan.]

[Reward: One-Tomoe Sharingan.]

"..."

Akira was stunned. "What? This is? I have a system?"

He had often wondered when he first arrived in the Naruto world if he would receive a cheat system like in so many online fan-fic novels, but no matter what he did, there had been no sign of one. Over time, he had accepted that he had to rely on his own hard work with his amazing talent to grow stronger.

Now, after all these years, it appeared that he was indeed a time traveler with a cheat after all. But what was with this reward of a one-tomoe Sharingan? He was already far beyond that, having achieved the Mangekyō Sharingan. Was the system serious?

Akira chuckled to himself. "At least....No, maybe it will be of some help for me in the future. I think?"
