Uchiha Yusuke

In a small grove near Konoha, two boys were engaged in a fierce hand-to-hand spar, the sounds of their rhythmic collisions ringing out incessantly.

Though young, both boys were clearly experts in taijutsu; every strike was executed with lightning speed and immense power, whipping up gusts of wind throughout the woods.

One of the boys wore a green jumpsuit and sported a comical mushroom haircut, his thick eyebrows alarmingly bushy and his nose significantly larger than most, marking him as a young Might Guy.

"Yusuke, fighting you is truly the best! But please be careful, this is my final move," Guy said, dripping with sweat yet grinning with delight at the other boy.

The boy sparring with him had black hair, a handsome face, and a pair of narrow eyes as calm as still water.

He wore the standard-issue flak jacket of a Konoha ninja, with his forehead protector tied around his left arm. On the back of his vest, a red-and-white fan symbol clearly indicated his affiliation: the Uchiha Clan.

"Konoha Gouriki!" Guy roared, preparing to launch his attack, but the boy known as Yusuke suddenly cut him off.

"Wait!" Yusuke held up a hand, signaling a halt.

"Don't tell me you're afraid, Yusuke? Have I, Guy, finally beaten you at taijutsu for once?" Guy asked, tears of joy welling up as he saw Yusuke call for a stop.

Yusuke said calmly, "Your focus is too centered on your opponent, leaving you with no awareness of your surroundings. Izumi has already arrived, and I need to head back for dinner. Let's call it a day."

"Big brother! Mom says it's time to come home for dinner!" No sooner had Yusuke finished speaking than a young girl's voice drifted over from nearby.

A petite girl in purple clothes emerged from the trees. This was Uchiha Izumi, Yusuke's younger sister. She had long, jet-black hair, sparkling, lively eyes, and a charming, delicate face with a beauty mark just below the corner of her right eye.

Might Guy nodded in disappointment; he and Yusuke had a long-standing agreement that whenever Izumi came to call him, their sparring session would officially end.

The reason Yusuke set this rule was that Guy was simply too persistent; once he got into the flow of a fight, he couldn't control himself and would pester Yusuke relentlessly to continue, forcing him to establish this boundary.

"Alright, then let's spar again next time, Yusuke!" A brilliant smile returned to Might Guy's face. After waving goodbye to Yusuke, he shouted "Youth!" and sprinted out of the grove.

As he passed Izumi, Guy grinned, his teeth flashing with a brilliant white glint as he reached out and gave her a thumbs-up.

Seeing this, Izumi gave a sweet smile in return and flashed a thumbs-up back: "Good luck!"

Watching Guy's retreating back as he kicked up a trail of dust, Yusuke shook his head with a smile and stepped forward to scoop Izumi up. "Izumi, let's go home and eat."

Uchiha Yusuke had been in the world of Naruto for fourteen years; he was a transmigrator from Earth.

Back on Earth, he had watched Naruto and had a certain grasp of the plot, though it was only a general understanding, and he had long since forgotten many of the details. Moreover, he hadn't been very interested in the "god-tier" battles of the later arcs, so he had only skimmed them, leaving him ignorant of much of that information.

However, Yusuke was very clear about the fate of the Uchiha Clan. In a few years, the clan's prodigy, Uchiha Itachi, would slaughter the entire clan for the sake of the village's stability, leaving no one alive except his younger brother, Sasuke.

Yusuke could not tolerate such an act by Uchiha Itachi. Not only was he a member of the Uchiha Clan himself, but his parents and his sister, Izumi, were his inverse scales—he would never allow anyone to harm them.

Therefore, to take control of his own fate and that of his family, Yusuke worked even harder to improve his strength.

Before he transmigrated, Uchiha Yusuke was a scientist in multiple fields, possessing an extremely rich store of knowledge and highly efficient learning methods.

Relying on a cognitive ability far beyond his peers, Yusuke had consciously trained all his capabilities since he was young. It could be said that compared to most, Yusuke had already won at the starting line, and coupled with his unremitting efforts, the growth of his strength was shockingly rapid.

In the eyes of others, Uchiha Yusuke was a rare genius, mentioned in the same breath as his contemporary, Kakashi.

Both Yusuke and Kakashi had been promoted to jonin not long ago, though the two did not have much interaction.

Especially after the recent deaths of Obito and Rin, the already aloof and solitary Kakashi had stopped interacting with anyone outside of his missions.

Of course, Yusuke and Kakashi did have a certain connection; they shared a common friend—Might Guy. Perhaps this was a common trait among proud people: even if they had few friends, they were happy to have someone as simple and trustworthy as Guy.

Yusuke felt a great deal of pity for Kakashi. If it weren't for the series of blows he had suffered in recent years, this genius would have achieved far more than what was shown in the original Naruto story.

The current Kakashi barely continued to improve his own strength, using constant missions to numb his wounded heart. In Yusuke's view, Kakashi was simply squandering his talent.

Of course, pity was just pity; Yusuke had no time to worry about Kakashi. The current Yusuke was completely immersed in this world of ninjas, his scientific curiosity driving him to constantly delve into all kinds of knowledge related to shinobi.

Although the rules of the Naruto world were not the same as many on Earth—for example, on Earth, you ran faster by swinging your arms, whereas in the Naruto world, you ran faster with your hands kept still behind your back—the underlying logic remained the same. The way of researching and thinking about problems was universal, and with Yusuke's background as a scientist, he naturally had a huge advantage in studying various ninjutsu or scientific training methods.

Carrying little Izumi, Yusuke strolled along the country road, enjoying the time spent with his adorable sister under the beautiful sunset.

"Big brother, a little boy said today that you aren't a genius, and Izumi argued with him for a long time. Big brother is the most amazing!" Izumi said while being held by Yusuke.

"Oh? In the future, just pretend you didn't hear things like that. There's no point in arguing," Yusuke smiled, dotingly flicking Izumi on the nose.

"How can I do that? He said that you still haven't awakened the Sharingan, and that so-called genius is just something outsiders say; it doesn't count for anything in the Uchiha Clan," Izumi pouted, looking angry.

Yusuke laughed heartily: "You silly girl, you're usually so yielding, why are you being so competitive now?"

"I can yield on other things, but I won't stand for anyone speaking ill of big brother. You became a jonin at twelve years old! Even without the Sharingan, you're the strongest genius in the clan. No, the strongest genius in the whole village," Izumi huffed.

Although Yusuke's strength far exceeded his peers and he had already reached the rank of jonin, he had yet to awaken the Sharingan, a point often criticized by some within the clan. Most members of the Uchiha Clan were extremely proud—or to put it bluntly, arrogant—and possessed a pathological sense of pride regarding the Sharingan.

Many clansmen believed that the Uchiha Clan with the Sharingan was invincible, and in their eyes, Yusuke, who had yet to awaken it, remained a mediocre talent despite his personal strength. To them, they could easily defeat Yusuke just by having the Sharingan.

Yusuke himself was also quite puzzled by the delay in his awakening, so he had pored over many historical documents and conducted quite a bit of research.

In the end, Yusuke discovered that the necessary condition for awakening was for one's emotions to be subjected to tremendous stimulation; the most common trigger was a loved one or oneself being in grave danger. Only such intense stimuli could cause the Sharingan to awaken.

After understanding the requirements for awakening, Yusuke could only shake his head helplessly.

He had very few friends, and his family all stayed in the village and had never been to a dangerous battlefield. Because of his superior strength, he rarely encountered danger and could always resolve it, resulting in him reaching the rank of jonin without ever having awakened the Sharingan.

However, Yusuke didn't particularly care about this, because his true trump card was a weapon that had accompanied him to the Naruto world—a weapon that did not belong to this world.

At this moment, deep within Yusuke's soul, a katana surrounded by raging flames was suspended.

This katana had a slender blade covered in cloud patterns that looked like fire, shimmering with a crimson luster amidst the roaring flames. It was the oldest and most powerful fire-type Zanpakuto from Bleach—Ryujin Jakka!

Ryujin Jakka usually lay dormant in Yusuke's soul, but when Yusuke fought, he could summon it at any time.

Because the fiery nature of Ryujin Jakka had been subtly influencing Yusuke for over a decade, it had also made his fire-style Chakra extremely abundant and pure.

Yusuke was also very adept at leveraging his own strengths, focusing these past few years on the development of fire-attribute Chakra and its related ninjutsu.

However, Yusuke still could not fully control Ryujin Jakka; the power of this Zanpakuto was simply too violent, and it was only recently that he had mastered the state of Shikai.

Although it was merely Shikai, it still greatly increased Yusuke's strength, allowing him to shine brilliantly during the Third Shinobi World War and earn the title of Flame Tachi.

When Yusuke returned home with Izumi, a simple yet exquisite home-cooked meal was already prepared on the table.

"Yusuke, you're back. Come and eat quickly. You work yourself too hard during training; even though you're already a Jonin, you shouldn't push yourself so tightly," Uchiha Hazuki said with a gentle smile.

Uchiha Hazuki was the mother of Yusuke and Izumi. She looked to be around thirty, sharing a seventy-percent resemblance with Izumi, though she appeared much more mature.

Yusuke set Izumi down from his arms, sat cross-legged at the dining table, and said with a smile, "A ninja can never afford to relax. Putting in more hard work during ordinary times might just save one's life at a critical moment."

Hearing Yusuke's words, a look of sorrow appeared on Uchiha Hazuki's face: "So many people have died in this war. Within the clan, many familiar faces have suddenly disappeared. Sigh, I truly don't know how long the major ninja villages will continue to fight."

"Even though you are a Jonin, the ninja world is far too dangerous. You must be careful and cautious," Uchiha Hazuki continued to instruct Yusuke.

"I understand, please don't worry," Yusuke replied earnestly, then pressed his palms together and said, "I'm digging in."

After Izumi sat down, she prepared to begin her meal, likewise pressing her palms together and saying, "I'm digging in!"

In traditional Japanese etiquette, regardless of age, one must press their palms together before eating and say "I'm digging in" to show respect for the food and gratitude for having food to eat.

Watching the two of them finish dinner with a gentle gaze, Uchiha Hazuki brought out a stack of black clothes from the room: "Tomorrow morning, a grand memorial service will be held to honor all the comrades from the village who died in this war. I have prepared the clothes for you both; remember to change into them before you go."

"Another memorial service, huh?" Yusuke muttered.
