I Became Narutos Blackened Personality

…

Naruto's eyes widened in shock.

He spun around, heart pounding, only to see Mizuki sneering from a tree branch above.

"Mizuki-sensei!?"

His mind reeled.

"Why!? I did exactly what you told me to!"

The words left his mouth before he could stop them, frustration seeping into his voice.

Mizuki's expression twisted with rage.

His eyes narrowed, and his lips curled in disdain.

"You little bastard! You really think I couldn't see through your pathetic little trick?"

His face contorted with hatred as he leapt from the branch, landing gracefully in front of Naruto.

A Chunin—deceived by a mere Academy student.

If word got out, he'd never live it down.

And Naruto… he'd make sure he never lived past tonight.

Mizuki's tone became mockingly sweet, though his eyes gleamed with malice.

"Hand over the Scroll of Sealing, and maybe I'll be merciful."

But his murderous aura made it clear—mercy was never an option.

He wanted to drag this out, make Naruto suffer before finishing him off.

But Naruto, prepared by Fengxu, had already expected this.

With a mocking grin, he stuck out his tongue.

"Pffft! Like hell I'd give this village treasure to a pathetic spy like you!"

Then, without hesitation, he turned on his heel and bolted.

The moment Mizuki registered the insult, his face darkened.

His veins bulged, his breath ragged with fury.

"You worthless little brat!"

"You think anyone wants you? You're just a piece of trash!"

He jerked his arm back, grabbing the massive four-pronged shuriken from his back.

With a vicious swing, he hurled it forward—

A deadly whistle of steel slicing through the air.

But Naruto, already expecting the attack, sidestepped effortlessly.

Mizuki's eyes flickered in surprise.

He hadn't panicked.

Inside Naruto's conscious world, Fengxu's eyes gleamed as he studied Mizuki.

"Naruto, let me take over. You can't beat him."

But Naruto shook his head internally, still running.

"No need! I've been chased plenty of times before—he won't catch me!"

Despite trusting Fengxu at 33%, that trust was still fragile.

Any sign of trouble could make it drop instantly.

And more importantly, Naruto was still afraid.

He feared what would happen if he gave Fengxu control.

Would he kill Mizuki? Would he go too far?

So long as Naruto had any other option, he'd refuse to switch.

"Besides," Naruto grinned, "if I can't beat him, you can't either because we're the same!"

"I'll lose him, learn the Multi-Shadow Clone Jutsu, and finish this!"

But Mizuki was done playing.

His fingers tightened around his kunai as he closed the distance between them.

"Fox demon brat, I'll be taking your left arm!"

His footsteps accelerated, his strike swift and precise—

Kunai aimed directly for Naruto's arm.

But at the last moment, Naruto stopped dead, grabbing onto a tree trunk and shifting his weight.

Mizuki, moving too fast, overshot the attack.

His momentum sent him stumbling forward.

By the time he recovered, Naruto was already several feet away, laughing.

"HAHA! What a moron!"

"You call yourself a Chunin? My pranks are harder to catch than you!"

Mizuki's fists clenched, his entire body trembling with rage.

"You disgusting little fox!"

"Fox demon?" Naruto grinned, cupping his hands around his mouth.

"Mizuki-sensei, did you hit your head? You can't catch me, so now you're just making things up?"

Then, he turned and ran again, laughing.

"Sucks to be you! Try and keep up!"

But this time… Mizuki didn't chase immediately.

Instead, his lips curled into a slow, knowing smirk.

"Hehehehe…"

Naruto's steps faltered.

Something about Mizuki's tone sent a shiver down his spine.

"Naruto…"

Mizuki's voice was mockingly soft.

"Do you know why everyone calls you a 'fox demon'?"

Naruto's stomach lurched.

A deep, gnawing dread settled in his chest.

"What… What are you talking about…?"

[Blackening Value +2]

[Blackening Value +2]

Fengxu's eyes glinted in the subconscious world.

"Oh? Here it comes."

Mizuki's grin widened, eyes gleaming like a poisonous snake.

"It's because you ARE the fox demon."

Naruto froze.

His breathing hitched, his body trembled uncontrollably.

[Blackening Value +20]

[Blackening Value +30]

"You… what did you just say…?"

His knees buckled, and he collapsed onto the dirt.

His vision blurred, Mizuki's words echoing in his skull.

"I… I'm the Nine-Tailed Fox…?"

Mizuki laughed darkly, striding forward like a predator.

"That's right."

"You destroyed this village twelve years ago."

"You slaughtered innocent people."

"And you know why no one ever told you?"

He leaned closer, whispering coldly.

"Because they hate you."

[Blackening Value +40]

Naruto's breathing became ragged.

"No… No… that's not true… I'm Uzumaki Naruto…!"

Mizuki's laughter grew louder.

"Then why do they all despise you?"

"Why has no one ever told you about your parents?"

His words cut deeper than any blade.

"Touch your cheeks, Naruto. You can feel it, can't you? The six whiskers. Proof that you're not human."

[Blackening Value +50]

Naruto's world shattered.

Mizuki lunged, grabbing his throat and lifting him off the ground.

With his other hand, he snatched the Scroll of Sealing from Naruto's grasp.

"Disgusting demon fox. The only reason the village keeps you alive is to use you as a weapon!"

"Even Iruka—your 'precious teacher'—his parents died because of you!"

Mizuki sneered.

"You think he actually cares about you? Or does he just pretend because Hokage-sama ordered him to?"

[Blackening Value +50]

Naruto's eyes were empty.

His body limp.

Mizuki's grin widened in pleasure.

"Everyone wants you dead, Naruto."

His kunai gleamed in the moonlight.

"So do the world a favor—"

He raised the blade high—

"And DIE!"

[Current Blackening Value: 3920]

"System."

"Switch personalities."

[ The main personality has completely collapsed. Personality switch successful. ]

A small hand shot up—

Gripping Mizuki's wrist like an iron vice.

A voice, cold and emotionless, echoed in the night.

"Who exactly do you want to die?"
