"Sano... how is Test Subject Six's physical condition?"
Hyuga Feng stood before the Byakugan crystal ball, as he always did.
"Clan Head, Test Subject Six's physical characteristics are normal, and her organs are developing well."
Sano spoke as he looked at the experimental data in his hands.
"Hmm..." Hyuga Feng smiled for the first time in a long while.
Test Subject Six was the only successful test subject so far.
Perhaps she really could awaken those legendary eyes.
When he was young, he had once wandered into the mountain behind the Hyuga Clan Compound.
Inside a cave, he had witnessed the most unforgettable sight of his life: countless Byakugan depicted on its stone walls.
The collected Byakugan had been fused into a single Ultimate Byakugan.
That Ultimate Byakugan was beautiful, like a holy angel in the heavens.
However, the writing on the mural was incomplete. Only a few phrases were clearly legible.
[Consolidate... eyes... forge... the purest... power... destroy heaven and earth...]
At first, he had not taken it seriously.
But when he dreamed of those strange things...
He had remembered it, though he had no idea whether the mural's claims were true.
Nor had he dared to try it rashly.
However, after collecting Byakugan from the battlefield and completing his first experiment, he had finally confirmed that it was feasible.
Yes, the fused Byakugan had indeed become purer, and its chakra consumption had decreased as well.
This made him all the more certain it could be done.
"In another six years, we should be able to proceed to the next stage!"
Sano nodded at his words.
"Of course. The longer we wait, the better her development will be, and the greater our chances of success."
"However, waiting until she reaches adulthood would be ideal."
Hyuga Feng shook his head. He could not wait that long. He needed power now.
The image of that pale-skinned little girl flashed through his mind.
He felt a little regretful. Had he known, he would not have placed the Caged Bird Seal on her so soon.
Her eyes were probably quite pure.
The weather was clear, and the sun shone brightly.
Training Ground Eleven, Konoha.
Yui and Nai Hyuga were practicing ninjutsu together.
"Body Flicker Technique..."
She formed hand seals with both hands.
Yui paused midstep, and her body vanished from where she stood.
Whoosh-
A second later, she appeared six meters away.
"I... did it..." Yui turned to look at the marker behind her in amazement.
"Yay... Yui, you're amazing! You've learned the Body Flicker Technique in just a few days."
"This is C-rank ninjutsu, too," Yui praised from beside her.
Yui smiled.
"It's because you taught me so well, Nai..."
A few days earlier, the Ninja Academy had given them a summer break of a little over ten days.
So Nai Hyuga had begun teaching her ninjutsu.
"Oh, right, Nai, come here for a second." Yui handed her a small piece of paper.
Using the papermaking techniques from her previous life, Yui had turned the bark of a chakra tree into chakra paper.
To her surprise, the paper worked just like it did in the original story. Feeding it just a little chakra would reveal one's chakra nature.
Taking the chakra paper, Nai Hyuga looked at it in confusion. "What's this?"
Yui placed another piece of chakra paper in her palm.
"Nai, watch closely. I'll demonstrate it once."
At her words, Nai Hyuga shifted her gaze to Yui's hand.
But as she watched, nothing seemed to happen.
No, there was a fluctuation in chakra.
Seeing Nai Hyuga's puzzled expression, Yui chuckled softly.
Then she opened her hand.
Nai Hyuga could now clearly see what had happened in her palm.
The paper had split in two, with one half wrinkled and the other damp.
"Wow... Yui, how did that happen?"
Seeing Nai Hyuga's bewilderment, Yui began to explain.
"This is chakra paper. It's used to test a ninja's chakra nature."
"Once you channel chakra into it, the paper changes according to your chakra nature."
"If it splits in two, that's wind. If it wrinkles, that's lightning. If it gets wet, that's water. If it turns to ash, that's fire. If it turns to earth, that's earth. The more chakra natures a ninja has, the greater their talent for ninjutsu."
After hearing Yui's explanation, Nai Hyuga grew excited.
Suddenly, a faint rustling came from the nearby bushes.
Yui's expression turned serious. She glanced in that direction but saw nothing unusual.
Perhaps... she was overthinking it!
Beside her, Nai Hyuga had noticed nothing. Following Yui's instructions, she channeled chakra into the paper.
But the final result disappointed her.
"The paper split in two, and both halves were damp."
"Aww... I thought I'd have a real talent for ninjutsu," Nai Hyuga said dejectedly.
Seeing Nai Hyuga's disappointment, Yui encouraged her. "Nai, having more chakra natures isn't necessarily better."
"If you master even one of them, you can still become a powerful ninja."
"Take the Second, for example. He was famous for his mastery of water release ninjutsu."
"Besides, even if you don't have other natures, you can acquire them through training."
At those words, the light returned to Nai Hyuga's eyes.
"Yui, is that really true?"
Yui nodded.
"Of course it is."
"Let's stop talking about this for now!" Yui changed the subject. "Oh, right, I still haven't quite gotten the hang of the Body Flicker Technique you taught me. Could you show me a few more times?"
Yui spoke with a smile.
Nai Hyuga was a little puzzled by Yui's words. Hadn't she already learned it?
"Yui..." She was about to ask, but Yui kept winking at her.
Seeing her expression, Nai Hyuga caught on.
Yui had probably noticed something.
In that case...
"Mm..." Yui agreed with a smile.
"For the Body Flicker Technique, you form a one-handed seal with two fingers together, then use chakra to activate your body's cells. That lets you run really fast!"
Yui began following Nai Hyuga's instructions.
She brought two fingers together to form a seal and activated her body's cells.
Whoosh-
With a rush of air, Yui vanished from where she stood.
Nai Hyuga looked around, trying to figure out which direction she had gone.
The next instant, a scream rang out behind her.
"Aaaah-what are you doing...?"
Nai Hyuga jumped, immediately growing anxious at the scream.
But once she realized it was not Yui's voice, she relaxed.
She looked toward the bushes behind her.
"Byakugan, activate."
