Naruto: Unlimited Kekkai Genkai

Autumn, 39th year of Konoha—nightfall.

The evening breeze was cool, rustling the fallen leaves as autumn deepened. In an ordinary house within the civilian area on the east side of Konoha Village, the doors and windows were shut tight, and the curtains drawn. The room was dim, illuminated only by the faint light of a few candles.

The furnishings were sparse. Aside from a bed and a couple of chairs, there was only a square table, and standing in front of it was a boy—Ishigami Hara.

His long, light red hair, uncommon in these parts, was loosely tied into a ponytail. He wore simple, everyday clothes, but his appearance stood out—red lips, fair skin, and strikingly defined features. Handsome and calm, he gazed intently at the items on the table in front of him.

There wasn't much—just some bottles and jars. Inside were special liquids, some resembling blood, while others were hard to identify.

Ishigami Hara glanced at the wall clock and furrowed his brow slightly.

"It's almost midnight," he murmured.

The clock's hands moved slowly, and soon, the hour struck twelve. At that moment, a familiar mechanical chime echoed in his mind—just as it did every night after his arrival in this world.

[Ding! Daily settlement begins.]

[Midnight to 6 a.m.: sleep.]

[6 a.m. to 7 a.m.: wash and eat.]

[8 a.m.: exercise.]

[9 a.m. to 11 a.m.: study.]

[11 a.m. to 3 p.m.: eat and research.]

[3 p.m. to 5 p.m.: study.]

[6 p.m. to midnight: eat, exercise, research.]

[Evaluation: a boring day.]

Ishigami Hara smirked at the all-too-familiar evaluation and listened closely.

[Keywords extracted: sleep, wash, eat, exercise, study, research.]

[Settlement distribution in progress… distribution completed: sleep +1, wash +1, eat +3, exercise +6, study +2, research +2.]

He let out a long sigh. With a thought, a light screen—visible only to him—appeared before his eyes, displaying a list of eye-catching keywords.

[Sleep (4106/5000) lv3: fast sleep, deep sleep, lucid dreams.]

[Washing (5937/10000) lv4: decontamination, cleansing, beautification, fairy-like appearance.]

[Eating (12996/15000) lv5: fast digestion, enhanced taste, iron and copper teeth, stomach like a furnace, able to swallow anything.]

[Exercise (5/10000) lv4: physical fitness, strong bones and muscles, rapid recovery, active body.]

[Learning (4861/5000) lv3: photographic memory, enhanced comprehension, analogy.]

[Scientific research (537/1000) lv1: precise operation.]

[Cooking (1003/2000) lv2: delicious results, nutritional supplements.]

[Handicraft (532/1000) lv1: dexterity.]

Seeing this, Ishigami Hara's brow eased, and a smile finally crossed his face.

"I've finally reached level 4 in training, and my learning speed has improved. I wonder what kind of benefits this 'active body' will bring?"

Ishigami Hara was excited. He wasn't originally from this world—he was a time traveler. Thrust into this new life without any warning, he had been born with the memories of his past life. It didn't take long for him to figure out where he was.

The World of Ninjas- Naruto!

Like any ordinary person would be, Ishigami Hara had been filled with anxiety. The dangers of the Ninja World were undeniable. For civilians, even the smallest mistake could turn them into collateral damage, little more than cannon fodder in the wars between clans.

But fortunately for him, time travelers often had something special about them. Ishigami Hara was no different—he possessed a mysterious system, one that had no name but gave him unshakable confidence.

The system was simple in function. It settled his daily behaviors, converting ordinary actions like eating, sleeping, and exercising into skills.

These skills leveled up with experience, and as they advanced, they came with unique keywords—each representing a special ability or trait.

For example, the "decontamination" ability unlocked at level 1 for his washing skill allowed him to effortlessly clean dirt from his body without any need for soap or other products. Just a simple rinse was enough to make him spotless.

Upgrading the skill to level 2 granted "cleanliness," allowing him to remain fresh and hygienic for extended periods—an extremely useful ability.

At level 3, the skill unlocked "beautification," which pushed the boundaries of what was possible. Each wash not only refreshed him but also slowly perfected his appearance over time, creating an effect almost akin to slow, natural plastic surgery. It was the reason he looked so strikingly handsome in this life.

And now, with the skill at level 4, he had unlocked the "fairy-like appearance" trait, which took his looks to an even more surreal level.

But what exactly was a "fairy-like appearance?"

It was the appearance of someone beyond this world—impossibly good-looking, with an ethereal charm and grace that made him seem otherworldly. His beauty was now so refined that it no longer felt human, as though a celestial being had descended to the earth.

To put it simply, if Ishigami Hara didn't keep this trait turned off, he wouldn't even dare to step outside. Even with only the level 3 "beautification" active, he had already earned the title of the most handsome man in Konoha, a label the villagers had collectively acknowledged.

They had even started calling him a "human inccubus" due to his unnatural allure.

This level of beauty alone made Ishigami—an otherwise ordinary surname in the village—stand out and feel almost legendary.

The other skill traits also brought Ishigami Hara numerous benefits, enhancing his abilities in surprising ways. For example, the traits he gained from his exercise skill were invaluable. Not only did they grant him exceptional physical fitness and unbreakable bones, but they also pushed his endurance far beyond that of a typical person.

The level 3 trait of his training skill, "fast recovery," was especially remarkable. Since acquiring this trait, his body's ability to heal had reached astonishing levels.

Through experimentation, Ishigami Hara discovered that ordinary wounds could heal completely in just three to five seconds. While he hadn't dared to test whether he could regenerate limbs, he assumed that such a feat was beyond his current capabilities. 

Still, the fact that he could recover so quickly provided him with a major advantage. This rapid healing gave him a sense of confidence that few in the ninja world could match. In fact, he suspected that his physical prowess might rival that of the legendary First Hokage, Senju Hashirama, and he even imagined the possibility of mentally dominating others as a result.

Closing his eyes, Ishigami Hara focused on the changes happening within his body. He could sense it clearly—something was different.

His entire body itched, his eyes ached, his heartbeat quickened, and his blood flowed with increasing speed, as if something hidden within his bloodline was ready to awaken.

The sensation grew stronger. Ishigami Hara clenched his fists, focusing on the changes, yet he felt that something was missing—whatever lay dormant in his blood was still not fully awakened.

Suddenly, a light blue aura began to swirl around him—an overabundance of chakra surged from his body, causing the nearby furniture to shake and rustle in response.

"What's happening?"

Ishigami Hara opened his eyes and quickly scanned his body. Nothing seemed out of the ordinary at first glance. He rushed to the bathroom, gazing into the mirror, and finally noticed the change.

His hair—it had become even redder.

Before, his hair had been a light red, but now, it was as red as blood itself. Other than that, there were no visible changes to his body. However, the chakra within him was roiling, almost as if it was boiling.

Despite being only twelve years old, Ishigami Hara's chakra reserves already far exceeded those of ordinary shinobi, thanks to his many skill traits. Based on his calculations, his original chakra capacity was around five times that of a normal person—an impressive amount for someone born a civilian. But now, his chakra had suddenly doubled in size, a startling and terrifying increase.

He knew this was significant. For a commoner in the world of shinobi, possessing chakra equivalent to five times the ordinary was already a feat, and now it had grown to at least ten. This exponential rise in chakra was nearly unheard of, especially for someone without a known bloodline inheritance.

Though the surge in power was starting to subside, the change hadn't stopped completely.

Staring at his vivid red hair, Ishigami Hara's thoughts turned to a familiar figure—Uzumaki Kushina. 

"Does the 'active body' trait unlock some dormant potential within me? This hair color... it's something only a pure Uzumaki bloodline could produce."

Ishigami Hara's expression grew thoughtful, almost bewildered. 

"It seems I'll have to uncover the truth over time."

But he didn't linger on the thought. He was used to the slow, gradual discovery of the effects tied to his various skill traits. After all, most of the abilities he had gained through the system had only revealed themselves bit by bit as he experimented.

Even now, the full potential of his level 3 "dream" ability from the sleep skill remained a mystery. Every night, Ishigami Hara made sure to sleep without fail, determined to understand what this ability truly offered.

Tonight was no different. After lying down to rest, Ishigami Hara quickly drifted into a deep sleep. But unlike previous nights, something unexpected happened.

For the first time since his sleep skill had turned into an ability, Ishigami Hara dreamed again.

He found himself in a vast, starry expanse. The sky was an endless azure blue, and countless stars hung in the distance, each one radiating a strange, ethereal energy. It was as though every star contained a complete dream, pulsating with its own unique presence.

Curiosity pulled him deeper into this dream world. He wandered from one star to the next, feeling the lingering chakra within each. Yet, one dream in particular seemed to call out to him, tugging at his very core with an inexplicable attraction. Without thinking, Ishigami Hara reached out and touched it.

Buzz...

The dream vanished instantly, but just before it disappeared, Ishigami Hara had the distinct sensation of bringing something back with him from that dream world.

When he opened his eyes, the first rays of morning light were already peeking through his window.

But before he could process what had happened, a menacing voice boomed in his mind.

"Damn Uzumaki brat, did you drag me out of the underworld? How the hell did you do it?"

Ishigami Hara immediately frowned. The voice was full of anger and malice, and it echoed inside his head with a dangerous intensity.
