"Nii-san!"
"Train shuriken with me!"
Land of Fire, Konoha.
The Uchiha had already been forced to move from the village center to the outskirts, pushed into a new clan compound.
A boy of five or six, dressed in the standard Uchiha outfit, ran step by step to the brother who had just returned from a mission.
One look at the limitless expectation on his small face made it clear he had been waiting a long time.
Unfortunately.
The teenager before him sighed and gave a small shake of his head.
"Next time, Sasuke."
Just as he feared.
The boy pouted, clearly unhappy with that answer.
He had not waited only for training tips. More than anything, he wanted a few more words with the person closest to him.
Perhaps seeing through Sasuke's thoughts, Itachi helplessly crooked a finger at his little brother.
His fingertip was already poised, ready to tap Sasuke's forehead when he came over, followed by the usual promise of next time for sure.
Unfortunately.
The brother who seemed so simple suddenly flashed a mischievous smile, stepped back two paces, and waved.
"Duck not necessary!"
"If you have things to do, Nii-san, go do them."
"I'll find Second Brother. Later!"
Right, he had a second brother.
Born only a few minutes earlier than Sasuke, but still his Second Brother.
Just mentioning him made Sasuke shiver as he shook his head. With eyes that nearsighted, thousands of degrees if you believed the rumor, could Second Brother even see the target?
With those doubts, Sasuke headed for the Uchiha-only training grounds.
Itachi watched his back and fell into thought.
Second brother, little brother.
They were both his brothers.
No matter what his brothers were like, he would love them as their elder.
Only...
"Clan, village."
Weariness and confusion flickered in his eyes. Itachi sighed and turned away.
...
The relocation filled most of the Uchiha with resentment.
For Amane, it only made life easier.
He truly did not see what was so great about the village center anyway.
Crowds on every side, a constant feeling of eyes on your back.
The new compound covered a wider area, and the clan had exclusive use of its own training grounds. Quiet and elegant surroundings suited training perfectly.
Of course, to the Uchiha this was a humiliation beyond doubt.
With this move, Konoha's leadership had planted a spark in the clan that could ignite a coup.
"Hu!"
"Ha!"
BANG!
On the training ground, a small figure hammered punches into a wooden post.
His fist was small, but each strike made the joints shudder. It looked as if one more blow would shatter the fragile post to pieces.
"Second Brother!"
A childish call came from behind.
The boy's movement slowed. He turned his head.
Warm as winter sunlight, his smile made Sasuke lift his hands, wanting to throw his arms around Second Brother and share his excitement.
Unfortunately.
The refined and gentle boy raised his left hand and waggled a finger, signaling Sasuke to stop, then spun in a flash.
He drew breath and centered himself.
Grace fell away, replaced by a sudden ferocity as he raised his right fist.
VMMM!
Fire gathered over his knuckles, hot air rolling out in a wave.
Gentleness and violence flowed from the same person. He was still young, yet the contrast gave him a striking charm.
"Ultimate, Style One Hundred Twenty Four."
"Wild Bite!"
BOOM!
Flame flared. The next instant, the already fragile post exploded into fragments.
The remains crashed to the ground. A closer look showed the inside had been burned clean through.
He turned back, relaxed.
Uchiha Amane glanced at his system panel, then gracefully pulled out a towel to wipe the dust from training off his hands.
Not bad.
As someone who did not exist in the original story, he was without question a transmigrator.
The identity was odd, though.
He had somehow become Uchiha Itachi's younger brother, the twin born a few minutes before Sasuke.
On top of that, his nearsightedness from his past life had apparently come along for the ride, straight from the womb.
With another clan this might not matter, but this was the Uchiha, a people who lived by their eyes.
Luckily, he had activated his golden finger.
A fierce cheat called the Allworld Fist King System.
It had one purpose: to forge the most domineering taijutsu grandmaster in the world of shinobi.
In this world, the fist was the hard truth.
Compared to other cheats, Fist King One was neither overwhelmingly strong nor truly weak, but as early combat power it was more than enough.
Host: Uchiha Amane.
First Fist King Lineage: Kusanagi Kyo.
Unlock Progress: 17%
Move Unlocked: Ultimate One Hundred Twenty Four, Wild Bite - Intermediate Taijutsu.
Daily Quest: Practice the Fist (Completed)
Dominance Points: 79.
The system was simple and direct. Complete the daily quest or train on his own to advance the lineage and gain techniques.
All abilities ignored their original energy systems and were fueled by chakra.
Considerate and powerful. At certain thresholds, a second and even third lineage would unlock. From what Amane knew, Kusanagi Kyo was not particularly top tier among the system's lineages.
If luck favored him, one day he might roll the power of that bald hero who defeated foes with a single punch. That would be enough to let him strut across the shinobi world.
Still, Amane was not greedy. Techniques and abilities were only tools. The one who truly controlled growth and strength was himself.
In this clan, a strong heart was essential.
Uchiha.
Amane was five now, which meant the clan's downfall was not far off. Time was running out.
He adjusted his glasses and, with his usual courteous smile, walked toward his little brother, Uchiha Sasuke, who had been born a few minutes after him.
Only by living with him would you realize that the future king of cool from the original story, the kid who maxed out the art of showing off, was nowhere near so off-putting when he was small.
He was even kind of adorable.
At the very least, Sasuke respected this older brother.
"Second Brother, got a Hua-zi?"
Maybe a bit too excited, Sasuke jogged over and pulled an unopened pack of cigarettes from his shirt, something he had just bought while passing a shop, and held it up with both hands.
Tch.
Hua-zi?
Amane was speechless. How could this world possibly have Hua-zi?
The kid had even picked up his catchphrase.
In his past life he had been a heavy smoker. Even after crossing worlds, he sometimes snuck off to a quiet corner for a stick.
Sadly, Sasuke had seen him that day.
Amane pushed his glasses up, accepted the offering with solemn care, and snapped his fingers. A bead of flame bloomed at his fingertip.
The easy flourish made Sasuke's eyes go wide.
"Second Brother!"
"That trick."
"Please teach me!"
