"Naruto, I'm ready."
Yūgao's voice was filled with softness. When she said "ready," it meant her power had drastically changed in recent days.
Thanks to the combined benefits of Yang Release and the Kyūbi's chakra, Yūgao's strength had increased considerably.
Kyūbi, that terrifying creature, only needed to share an tiny fraction of its power for anyone to benefit from it.
In the original story, Kakashi made a pertinent remark:
"With the Kyūbi's chakra cloak, my ability to use Kamui has at least tripled!!!"
This clearly showed how formidable Kyūbi was. Its power was truly too dangerous.
After all, Hashirama Senju's strength couldn't be shared, whereas Kyūbi could distribute its energy as if it were free.
Of course, Naruto's Yang Release was also not ordinary.
As Asura's chakra reincarnation, the nature of his Yang was fundamentally different from others.
If one were to classify the quality of his chakra according to shinobi levels, then... his "Yang nature chakra" had at least Six Paths level potential.
Yūgao, having received these two forces simultaneously, could only become stronger.
This delighted Naruto, confirming that his path to "salvation" was the right one.
Certainly, Yūgao had been "overdosed," but it had indeed worked!
As for Aoba, she had received a diluted version, simply via a milk drink infused with Yang Release, to observe its effects.
"Good, let's go out."
Naruto headed to the garden to assess Yūgao's progress.
Click.
The door closed.
Once the two had left, Aoba, still in the washroom, spat out the tap water.
No human being could swallow liters of water at once.
The result was that she ended up regurgitating everything.
But what filled her with despair was that no trace of Naruto's "milk" was expelled.
"How... is this possible... Mmh~!"
Suddenly, a change occurred.
Aoba's slender and toned body, forged by Gentle Fist training, began to tremble.
An unbearable heat rose within her.
"Hot... too hot..."
Aoba groaned, getting up with difficulty.
She clung to the sink, then fumbled toward the doorknob.
After stumbling to the living room, disoriented, she collapsed to the side.
Then, she writhed on the floor.
The excessive heat burned her from the inside, all the way to her face.
Stars danced before her eyes.
An excess of "vital force" caused this effect.
As a normal and healthy human, her body didn't need an additional supply of life.
Yet, she had been forced to take it.
"Mmh~..."
A tear rolled down her cheek.
She clenched her lips, able only to endure... endure…
Backyard
Naruto took his stance, facing Yūgao.
"Let's begin!"
With a leap, Naruto rushed at her.
Yūgao reacted instantly.
Their body techniques clashed, blows and counter-attacks following one another.
Surprisingly, Yūgao managed to keep up with Naruto's pace.
"Oh?"
Naruto raised an eyebrow, his pupils slitting like a fox's.
He lightly drew on Kyūbi's strength.
Their duel resumed, but this time, Yūgao began to lose ground, her physical strength being inferior.
Nevertheless, she still managed to react.
Finally, they stopped. Naruto nodded, satisfied.
"Not bad... Your strength has increased by at least one level."
The Tokubetsu Jōnin were classified by tiers.
Yūgao was previously at the lowest level.
Without intervention, her progress would have depended solely on time and experience.
That was the rule in the shinobi world.
But now, the additional power Naruto had given her had propelled her to the level of Genma Shiranui or Raidō Namiashi.
Among the Tokubetsu Jōnin, the strongest were undoubtedly Ibiki Morino and Iwashi Tatami.
Naruto was convinced that with a few more
"sessions," Yūgao would surpass them.
"Naruto, it's thanks to you..."
Yūgao adjusted her mask to the side, revealing a radiant smile.
At first glance, everything seemed normal.
But in reality, her personality and thinking had been altered…
Naruto preferred to call it "corruption."
"Uzumaki Naruto, you have warped her mind..."
Kyūbi, incredulous, had drawn this conclusion.
Even he, in the worst case, only made his host uncontrollable, a temporary effect.
But this demon Naruto had completely distorted a person!
"No~, Kyūbi, don't talk nonsense~."
Naruto once again used his favorite phrase.
As he was about to continue his lies, Kyūbi growled:
"Give up, little demon. No one is more evil than you!"
Even though Kyūbi had uncovered part of the truth, Naruto maintained his mask.
If a hero weren't hypocritical, would he truly be one?
Thus, Naruto declared:
"Kyūbi, you're wrong... I just want to save everyone. If Yūgao becomes stronger, then Hayate won't die in the future... Anyway, you wouldn't understand~."
Kyūbi: "Humph..."
