The instant the system's voice faded, Sasuke felt a faint electric twitch run through his body.
His previously calm chakra suddenly turned sharp and lively—carrying a swift, cutting edge.
He could clearly sense a strange resonance forming between himself and the element of lightning.
As if with just a bit of focus, he could unleash a Lightning Release technique on the spot.
Lightning Release!
Sasuke's heart surged with excitement.
The Uchiha clan excelled in Fire Release and eye techniques.
Fire Release—he already awakened.
But Lightning Release, especially at age six, and with innate affinity?
That was a god-tier starting hand.
With both Fire and Lightning natures, plus the future Sharingan, his combat potential would far surpass the Sasuke of the original story.
"Good."
Itachi noticed the burning determination in Sasuke's eyes. A faint, rare smile curved his lips—filled with approval and hope.
"Starting tonight, I'll set aside one hour every evening to personally guide your training."
"Really?! Thank you, Brother!"
Sasuke's joy was genuine. He lunged forward and hugged Itachi's arm tightly, voice bubbling with excitement.
The sudden closeness made Itachi freeze for a moment.
Then he slowly raised a hand and gently ruffled Sasuke's hair—so soft, so tender, it didn't match the cold prodigy image he carried.
In Sasuke's inherited memories, Itachi loved him dearly but rarely showed such overt affection.
He was usually the strict, composed older brother.
"No need to thank me."
Itachi's voice softened noticeably.
"You are my little brother. I want you to grow strong—strong enough to protect yourself… and to protect the Uchiha."
Sasuke could feel the sincerity behind his words.
Warmth bloomed faintly in his chest.
In his previous life, he never had an older brother.
Now, this world had given him something he once lacked.
Even if the future held tragedy…
At this moment, the warmth was real.
And that was enough to strengthen his resolve.
This time—he would protect this bond.
He would prevent the massacre.
He would rewrite fate.

When they returned to the Uchiha compound, Uchiha Fugaku had just finished handling clan affairs and was practicing swordsmanship in the courtyard.
The gleaming blade sliced through the air with sharp precision, each movement refined through years of discipline.
Hearing footsteps, Fugaku paused and sheathed his sword with a crisp clang.
Sweat trickled down his chiseled face as his sharp gaze landed on Sasuke.
"Registration is complete?"
His tone was stern as always.
"Yes, Father."
Sasuke replied respectfully, his eyes firm—not timid, but steady with a maturity far beyond his age.
"Starting tomorrow, you must meet the standards of a ninja."
Fugaku stepped closer, looking down at Sasuke.
His presence alone carried a heavy pressure.
"The Academy teaches the basics. Real strength requires harsher training. Starting tonight, every morning you will train taijutsu for one hour. No slacking off."
"Yes, Father. I understand."
Sasuke straightened his small back and answered with unwavering determination.
"I won't disappoint Father's expectations… nor the honor of the Uchiha clan!
I will train diligently, become a warrior worthy of our name, and let the world see the power of the Uchiha!"
His young voice rang with conviction—such strength that it hardly sounded like words a six-year-old could say.
A flicker of surprise flashed in Fugaku's eyes, quickly replaced by deep approval.
His stern expression softened ever so slightly.
He had always held high hopes for his younger son—hopes that Sasuke would inherit the Uchiha's will and grow into a true powerhouse. Sasuke's declaration just now struck straight at the center of his expectations.

Ding! Uchiha Fugaku's affection +3. Current affection: 73 (Close)!
Ding! Reward obtained: One-Tomoe Sharingan Awakened!

A warm surge of energy rushed into Sasuke's eyes.
He felt a faint burning sensation—
—and the world changed.
The courtyard became crystal clear.
He could see the precise arc of falling leaves, tiny cracks hidden along distant walls, even faint traces of chakra drifting in the air.
He instinctively wanted to examine every detail with his new Sharingan—but forced himself to stop.
Awakening the Sharingan at age six was far too shocking.
Exposing this now would only attract suspicion… or worse, the attention of Konoha's higher-ups.
He lowered his gaze, hiding the flash of crimson and the single rotating tomoe.
Inside, however, his heart roared with excitement.
One-Tomoe Sharingan!
The Uchiha's greatest bloodline power—unlocked just by raising Fugaku's goodwill!
With its enhanced perception, plus his Fire and newly awakened Lightning chakra natures, his strength already surpassed ordinary children… and might even match some junior genin.
"Father," Itachi said softly, "I'll guide Sasuke each evening—teach him chakra control and basic ninjutsu."
Fugaku nodded.
"That is good. Your talent and skill are unmatched in Konoha. Sasuke, follow your brother carefully. Do not waste your potential. Remember what you said today—
the honor of the Uchiha rests on your generation."
"I will!" Sasuke responded firmly, eyes burning with motivation.

That night, the Uchiha courtyard glowed with lantern light.
Itachi began by guiding Sasuke through the improved chakra extraction technique.
"Close your eyes. Focus. Feel the energy within your cells. Follow the method—slowly gather it into chakra. Control your rhythm; don't rush."
Sasuke followed every word.
The upgraded technique was completely different—what used to be obscure and clumsy now felt natural and smooth.
Energy flowed through him like a gentle stream.
With his newly awakened Lightning affinity, the chakra gathered even faster, carrying a faint electric sharpness.
He could clearly sense the lightning-chakra circulating—like a soft tingling under his skin—yet perfectly obedient and calm.
"Brother, like this?" Sasuke asked while guiding his chakra, simultaneously activating his Sharingan to observe the flow inside his body.
The improvement was dramatic—twice the result with half the effort.
"Good. Your control rhythm is excellent," Itachi said, unmistakable approval in his voice.
"Your perception is better than I expected. Your precision with chakra already surpasses many clan children your age. Keep it up."
