Pain.
A searing headache jolted Uchiha Eiji awake. He clutched his throbbing head, sweat dripping down his temples, as an unfamiliar ceiling came into focus. A frail body, a simple room with a futon…
'Did I… transmigrate?'
Moments ago, he was a burnt-out office worker who collapsed in front of his computer. Now, memories flooded his mind—he was a twelve-year-old "worthless" Uchiha, weak in Taijutsu, pitiful in Chakra, and often bullied. He had barely scraped through the Ninja Academy only because Konoha needed manpower after the Nine-Tails disaster.
"Bang!"
The door slammed open. Sunlight flooded in, revealing three sneering teenagers. The leader, Uchiha Genji, smirked.
"Yo, worthless Eiji. Heard you missed the target in shuriken practice again. Embarrassing the clan again, huh?"
They demanded the usual money for their snacks and other pleasures. The old Eiji would have cowered—but not this one.
"I don't have any," he said coldly.
Genji laughed, yanking him off the bed. Pain exploded as his body hit the wooden floor. Rage and humiliation boiled within Eiji.
'Why should I endure this? Where's my cheat?!'
"Ding!"
A mechanical voice echoed in his mind.
'Clan Supremacy System binding… Beginner's gift package issued.'
Warmth surged through his limbs, chakra flooding his starved tenketsu. His chakra level skyrocketed to Chunin level, and a burning sensation ignited in his eyes. When he lifted his head, his dull black pupils were now blood-red—
The One-Tomoe Sharingan.
The room froze. The bullies' sneers melted into shock.
"Sha… Sharingan?!" Genji stammered.
Eiji rose slowly, every muscle alive with power. Under the Sharingan, every movement, every twitch of fear, was crystal clear. A cold smile curled on his lips.
"So… What was it you said to me just now?"
The shock on Uchiha Genji's face quickly twisted into scorn.
"Hmph! So you awakened a One-Tomoe Sharingan. You're still a worthless nobody!" he spat, jealousy simmering beneath his disdain.
He lunged, fist cocked and crackling with meager Chakra, aiming to smash Eiji back into his place. But in the scarlet vision of the Sharingan, Genji's attack was painfully slow. Eiji saw every shift in his shoulders, every ripple of Chakra in his arm.
'Too slow.'
He tilted his body just enough for the punch to graze past and whipped his leg out. His kick smashed into Genji's supporting knee with a sickening crack. His leg bent at an unnatural angle.
"Ah!" Genji collapsed to one knee, screaming in pain, sweat dripping down his face. One move. That was all it took to topple the bully who had tormented him for years.
"Genji-nii!" His two lackeys panicked.
Uchiha Inaho rushed into hand seals, but Eiji's Sharingan had already read his Chakra flow. He formed his own seals faster.
"Fire Release: Great Fireball Jutsu!"
A roaring, meter-wide fireball burst from his lips, engulfing Inaho before he could finish his jutsu. With a scream, the boy slammed into the wall, charred and unconscious.
The last follower, Uchiha Jiren, went pale, legs trembling as Eiji's blood-red eyes locked on him. He stumbled back, voice breaking. "D-Don't come closer!"
Eiji's cold gaze pierced him. "Who called me worthless?"
Jiren crumpled to his knees, babbling excuses and begging for mercy. "It wasn't me! We—we'll never do it again! Eiji, spare us!"
Eiji let the silence stretch, savoring the shift in power. His fists clenched, blood singing with new strength.
'With Chunin-level Chakra and my Sharingan, these small fry can never touch me again.'
"Scram."
The bullies fled in terror, dragging Genji and the unconscious Inaho with them.
As the room fell silent, Eiji exhaled slowly. The warmth of power coursed through his veins; the world under his Sharingan felt sharp, clear, and his for the taking.
'From today, I am no longer the Uchiha who can be trampled.'
'Ding! Clan Points +50'
A translucent panel flickered in his mind, listing his newfound strength and a grim warning: the Uchiha Clan faced internal and external crises—annihilation loomed.
Eiji's eyes narrowed, determination hardening.
'I refuse to be another casualty of history. System… tell me everything about yourself.'
As Eiji's thoughts settled, the cold mechanical voice echoed in his mind once more.
'The Clan Supremacy System exists to aid the host in strengthening oneself and reviving the Uchiha Clan to its former glory.'
A translucent blue interface bloomed before his eyes, the Uchiha fan crest glowing faintly at the top. Below it were several main modules, each waiting to be explored.
He focused first on
Clan Name: Uchiha
Clan Points: 50 Points
Overall Strength: Quarter the strength at the end of the Warring Clans Era.
Warning: The clan is internally divided, suppressed by Konoha's leadership, and at its weakest in history.
Eiji's heart sank. He had known the clan was in trouble, but to see the proud Uchiha reduced to such a level stung like a blade. Once rivals of the Senju and the pride of Konoha, the clan now teetered on the edge of ruin.
"Fifty points… earned just for putting those bullies in their place," Eiji muttered. 'So, raising my prestige in the clan earns points.'
He opened the Member List next. A dense roster appeared, covering nearly every living Uchiha:
Uchiha Fugaku (Clan Head): Kage Level, Loyalty 75% (Clan), 0% (Host)
Uchiha Shisui: Kage Level, Loyalty 85% (Clan), 0% (Host)
Almost every name had two loyalty values—one to the family, one to him. His own host loyalty was abysmal. Understandable, since the original Eiji had been "worthless" in their eyes.
Then his gaze fell to his own entry:
Eiji – Strength: Chunin, Status: Regular Genin
Next reward: Upon selection to Konoha Military Police.
His eyes gleamed. The Military Police was the clan's backbone, controlling Konoha's police force. Joining would boost his standing, earn system rewards, and give him access to the clan's core.
Curious, he tapped System Store/Exchange.
A dazzling list appeared:
Fire Release Ninjutsu Encyclopedia – 10,000 Points
Lightning Release Chakra Mastery (Basic) – 5,000 Points
Sharingan Evolution Guide (Two-Tomoe) – 20,000 Points
Mangekyo Sharingan Activation Secret (Incomplete) – 100,000 Points
There were even rare items like Bloodline Enhancement Potion and Yin Release Potion. But with his meager 50 Glory Points, he couldn't afford the cheapest consumable.
'Earning points is my top priority', he realized.
A fierce flame of ambition burned in his chest.
Closing the interface, Eiji forced himself to breathe deeply. Excitement gave way to grim clarity. His Chunin-level strength and Sharingan were only the first step. Konoha's suspicion, Danzo's shadowy plots, and the clan's fractured state were mountains on his path.
But now, he had the means to change everything.
'I didn't transmigrate to watch the Uchiha perish again.'
He clenched his fists, his eyes gleaming with determination.
"From today forward, I will rewrite the fate of the Uchiha."
