Chapter 1 — Reborn as Sasuke
…My head… it hurts.
Where… am I?
Jen woke up surrounded by unfamiliar softness. A faint scent of cherry blossoms lingered in the air—nothing like the ever-present instant-noodle smell of his cramped rental room.
He pushed himself upright. What entered his sight was a refined, traditional Japanese room: sliding paper doors, tatami mats, and a small decorative katana set neatly in the corner.
This was not his room.
What the hell was going on?!
"Sasuke, are you awake? Come down for breakfast. Today is your first day reporting to the Ninja Academy, you know?"
A gentle female voice called from outside. The warmth in her tone was just right—yet it made Jen freeze in place.
That voice… and that name…
He instinctively touched his face. The skin was soft, tender—nothing like the roughness of his twenty-plus-year-old adult body.
His heartbeat spiked. Stumbling, he rushed toward the bronze mirror in the corner. The reflection staring back at him made his pupils shrink to pinpoints.
Jet-black short hair. Pale skin. A delicate, doll-like face. And those black eyes—still innocent for now, but destined to harden with cold hatred.
This was unmistakably Uchiha Sasuke at six years old.
Just as handsome as everyone watching behind their screens—talking about looks, of course, not the tragic backstory!
"I… I transmigrated into Sasuke?"
Jen—no, Sasuke—murmured to himself, mind blanking out.
As a die-hard Naruto fan, he knew the fate of this character better than anyone.
The lone survivor of the Uchiha massacre. A child who carried the blood feud of an entire clan. Someone who spent his life chasing the shadow of his brother, Uchiha Itachi, consumed by revenge.
Only to be pulled back from the darkness by his best friend Naruto, choosing eventually to live for the sake of the village.
"Sasuke? Why aren't you coming down yet?"
The door slid open with a soft shhh, and Uchiha Mikoto stepped inside. Dressed in a simple kimono, she wore her usual gentle smile.
"Hurry now," she urged softly. "Your father and brother are waiting for you."
Seeing a face that should only exist in anime made Sasuke's heart clench hard.
This was Uchiha Mikoto—Sasuke's mother. A woman so gentle it made your chest ache… yet she would still fall victim to the tragedy of the Uchiha massacre.
He forced down the turmoil brewing inside and imitated the Sasuke from memory, giving a small nod.
"Okay, Mom."
Following Mikoto downstairs, he entered the dining room—where the sight waiting for him made his breath catch.
Sitting in the main seat was Uchiha Fugaku.
Clad in the clan's formal attire, his expression was stern as ever, eyes sharp like an eagle's. The head of the Uchiha clan, and Sasuke's father.
Beside him sat a quiet, composed boy in a black bodysuit layered with the Uchiha crest—black hair, black eyes, cold aura.
Uchiha Itachi.
Only eleven years old, yet already acknowledged throughout Konoha as a prodigy.
Now, he still carried a trace of youthful softness—none of the cold resolve he would later become known for.
Suddenly, a surge of foreign memories flooded Sasuke's mind like a crashing tide.
According to those memories, the massacre had not yet occurred. Right now, he was just a young Uchiha child, newly old enough to enter the Ninja Academy—living a "peaceful" life with both parents alive and his brother by his side.
Mikoto's tender care.
Fugaku's strict expectations.
Itachi's quiet, ever-present brotherly warmth.
"So… I really am Sasuke."
He exhaled slowly, heart a mess of emotions.
To be reborn in this dangerous world… and as the famously tragic Sasuke…
Was that fortune?
Or misfortune?
"Sasuke, today's your first day at the Academy."
Itachi was the first to speak, his calm voice carrying a gentle warmth.
"Once you finish eating, I'll walk you there."
Fugaku gave a curt nod as well, tone stern as always:
"At school, act with the dignity of an Uchiha. Do not shame the clan."
"Mm." Sasuke nodded again, doing his best to play the silent, reserved child.
He had just arrived in this world; though he'd absorbed Sasuke's memories, he still needed time to fully adapt.
Breakfast passed in a quiet, peaceful atmosphere.
After standing up, Itachi naturally took Sasuke's small hand.
"Let's go, Sasuke. It's your first day—I made time specifically to take you."
The warmth from Itachi's palm startled him for a second.
This was Itachi's warmth… and in Sasuke's memories, such closeness was completely normal.
He looked up at the boy beside him. Itachi's profile was sharp yet calm, serene enough to bring a sense of comfort.
"…Brother," Sasuke whispered without thinking.
In his previous life, he'd grown up in a single-parent home.
He'd never experienced having an older brother.
And now, through a twist of fate, that childhood regret had been filled.
"What is it, Sasuke?" Itachi asked, slightly puzzled.
"Nothing!" Sasuke shook his head.
The two of them walked out of the Uchiha compound and made their way down the street toward the Ninja Academy.
Morning sunlight bathed Konoha in a warm glow.
Villagers in casual clothing strolled about, while shinobi with tool pouches hurried by.
Familiar sights filled his vision—
The buildings lining the streets,
The distant Hokage Rock,
The subtle presence of chakra in the air.
Everything told Sasuke one thing:
This wasn't a dream.
He was truly in the world of Naruto.

Sasuke froze—then a wave of joy surged inside him.
A goodwill system?!
A transmigrator's golden cheat finally arrived!
Just by raising people's affection, he could gain power?
Grow stronger quickly?
That was practically a cheat designed for him!
While others had to train day after day, risking their lives for every improvement…
He just needed to build relationships and max out affection to receive boosts effortlessly!
He glanced instinctively at Itachi beside him. The system displayed Itachi's affection as 80 (Close).
This was Uchiha Itachi!
One of the strongest shinobi in the entire world.
If he maxed out Itachi's affection, the rewards would be insane.
