The house was shrouded in darkness.
Naruto was fast asleep.
It was already 10 PM, and not a single sound echoed throughout Konoha.
It was in this shadowy atmosphere that an unexpected visitor appeared...
Uchiha Izumi silently opened the window and stepped inside.
The moonlight lit up the wooden floor, and also… Uzumaki Naruto's face.
His small, sleeping face looked so innocent, so far from the cruelty he had shown during the day.
"What a good actor..."
Izumi's chilling whisper slipped from her delicate lips.
At that moment, her hidden protector, Yugao, stationed on the roof of a nearby building, noticed the intruder.
"Uchiha… Izumi?"
Quickly rising, Yugao watched from her vantage point as the young Uchiha entered Naruto's home.
"What is she doing here?"
Unaware of what Naruto had done to Izumi, Yugao sensed no danger.
Izumi was just a genin.
Although… being a genin with a three-tomoe Sharingan was almost laughable.
Not taking her seriously, Yugao didn't know Izumi had changed.
As the proverb says: 'After three days apart, look at a man with new eyes.'
Having awakened the Mangekyō Sharingan, Izumi had surpassed Kurenai's level.
Even after being strengthened twice by Naruto, Yugao was still just a jōnin.
Whereas the Mangekyō Sharingan catapulted its user straight to Kage-level.
Not to mention…
The Mangekyō carried unpredictable ocular techniques.
So Yugao opened her window and leapt.
In the night, she looked like a fairy, dancing gracefully through the air.
"Uchiha Izumi..."
Landing on Naruto's balcony, Yugao reached out to confront her.
But suddenly… her eyes darkened, and she collapsed unconscious.
Izumi, having turned around, had used the Mangekyō's innate illusion to neutralize her.
In an instant, Yugao was paralyzed, with no time to react.
"Don't… get in my way."
With those chilling words, Izumi controlled Yugao and made her return to her original post...
Then, she closed Naruto's window, sealing out the night breeze.
"Heh…"
Izumi slowly approached Naruto, her sinister aura disturbing the Kyūbi.
"Damn… those cursed eyes, that's the Mangekyō Sharingan!"
Experienced as he was, Kyūbi recognized it instantly.
He never imagined Naruto would dig his own grave.
By tormenting this human, he had triggered her awakening!
Was she here to cut off his head?
Kyūbi cursed Naruto internally and tried to wake him.
But Naruto kept snoring.
Was he truly asleep… or pretending?
Izumi stared at Naruto, observing his disheveled posture and discarded blanket.
Her first reflex wasn't to cover him.
Instead...
She reached out her hand.
Her right hand, gloved in black silk, moved toward Naruto's throat.
That outfit, along with the gloves, betrayed meticulous preparation for a clean kill.
As a member of the Uchiha Military Police,
Izumi was steeped in criminal cases.
And when an enforcer of the law committed a crime… the evidence tended to vanish.
However, just as she was about to grab Naruto, she noticed something.
Or rather… something else.
"A monster!"
Her eyes widened slightly.
Even in the darkness, she remembered the evil beast that had wounded her.
It was here…!
Izumi changed targets.
She turned to the symbiotic beast, now awakened.
If Naruto was a jinchūriki, it made sense for him to have a beast linked to his life.
The creature, fully aware, let out a low growl of warning.
"Hmph."
Izumi sneered.
Now endowed with the Mangekyō, she had overcome her fear.
She reached out.
Her gloved fingers grabbed the symbiotic beast!
"Ahh… so this is the Nine-Tails demon fox..."
Her expression was ice-cold.
Kyūbi: "..."
"You still dare to defy me? To scratch and bare your fangs?!"
Her voice carried a grim authority.
She tightened her grip, strangling the beast.
"Trying to scare me off? Or wake your host? Huh, Kyūbi?"
Kyūbi: "..."
As Izumi increased the pressure, she murmured sarcastically:
"Ahh… is my strength too much? Sorry…"
"This is all because of you, Kyūbi..."
Izumi began to torture the symbiotic beast.
This usually terrifying monster now seemed helpless in her grasp.
Was this the power of the Mangekyō?
"Disgusting! Revolting beast!"
Izumi spat at the "symbiotic beast."
Kyūbi: "..."
"You killed my father… you destroyed me..."
She raised her left hand.
"Tell me… how should I punish you?"
Then, she gripped the creature's throat with both hands.
With this double hold, she seemed determined to kill "Kyūbi."
"It's all your fault… it's ALL YOUR FAULT!"
Izumi's emotions surged as she abused "Kyūbi."
"Ahh… you must be the one who corrupted this child! You poisoned his heart… damn you, Kyūbi!!"
Izumi poured all her rage onto the symbiotic beast.
This merciless torment lasted a long time.
Until…
"Kyūbi" finally gave way, a warm liquid spurting from its body.
It was… finally wounded.
Splattered with Kyūbi's "blood," Izumi hesitated for a moment.
The stench of the "cursed blood" made her breathing quicken.
"This filthy stench… the pus of a monster… dead… ha… I killed Kyūbi…"
Seeing the "symbiotic beast" wither,
Izumi let out a dark smile.
"Die! Disappear for good! That way… Naruto can walk in the light..."
With her task complete, Izumi, a victorious smile on her lips, stood up, opened the window, and disappeared into the night.
She ran with exhilaration, proud to have defeated Kyūbi.
"Hah… hah…"
But Izumi didn't notice that the "demonic blood" staining her face… was being rapidly absorbed by her skin.
