Hinata's current condition could already be confirmed as the Byakugan evolving toward the Tenseigan.
In fact, three years ago in Roran, under the influence of the Dragon Vein chakra, Hinata had shown a similar situation. It was just that there was no follow-up after that, and it hadn't been as intense as it was now.
Under normal circumstances, setting aside the method of fusing a large number of high-purity Byakugan, if one wanted to evolve the Byakugan into the Tenseigan, Otsutsuki clan chakra was absolutely necessary.
So generally speaking, no matter how high the purity of Hinata's Byakugan was, before Aoba took her to the moon, at most it should have been reverting toward Otsutsuki Kaguya's lineage, rather than evolving into the Tenseigan.
But Aoba just happened to be an exception.
His Tenseigan had evolved after obtaining both the Byakugan and Otsutsuki clan chakra.
In other words, within Aoba's body, there was extremely high-purity Otsutsuki chakra.
It was just that compared to his Sage Body and the Uzumaki clan's chakra, it seemed somewhat "fragile."
But over this past year, although Hinata was rather shy, under Yakumo's instigation, and combined with her large appetite, she hadn't held back on eating at all. With small amounts accumulating over time, it instead triggered a certain qualitative change.
Perhaps as long as she could steadily obtain a sufficient amount of Otsutsuki chakra from him every day, Hinata's eyes evolving into the Tenseigan would be a natural process.
And the current situation was probably because the intake hadn't been very stable.
Come to think of it, he really hadn't given Hinata any chakra for quite a while.
Instead, it had led to a kind of uncontrolled "fetal movement" situation.
"Mmhh?"
Hinata still didn't know what was happening. She only felt a sudden sweetness flowing into her mouth, along with a faint taste of blood.
But this seemed to be Aoba-kun's hand, so she let out a soft, cute muffled sound.
"It's fine, just swallow it."
Aoba said with a smile, comforting her.
"So does that mean Onee-san will be fine as long as she drinks Aoba-nii's blood?"
Hanabi tapped her lips, her gaze fixed tightly on Aoba's wrist.
She looked like she also wanted to have a taste.
"It's not that she'll be completely fine, but it should relieve it. I'll take your sister somewhere later. Once we get there, it should be completely resolved."
As Aoba answered, he used his other hand to poke Hanabi's cute cheek, teasing her.
"You want to try it too?"
"If Onee-san can, why can't I?"
Hanabi pouted at him, her eyes rolling slightly.
"It's not that you can't, it's just… uh!"
Before Aoba could finish speaking, he suddenly felt the finger that had been poking Hanabi's cheek get bitten.
Her little tiger teeth kept grinding against his fingertip, as if trying to bite through it.
"..."
Aoba couldn't help twitching the corner of his mouth. Since getting bitten a couple of times wasn't a big deal, he simply let her do as she pleased.
He just didn't know whether Hanabi would also end up in the same situation as Hinata.
In the movie storyline, Otsutsuki Toneri was able to transplant Hanabi's eyes to evolve the Tenseigan, which meant her eye purity was also sufficient.
If little Hanabi bit him a few more times, then wouldn't that make it two supreme beings in one family?
Aoba didn't spend much time "treating" Hinata, because it wasn't really treatment to begin with.
He just needed to replenish enough protein… no, chakra.
By the time Aoba came out of the room with Hinata, whose eyesight had recovered, and Hanabi, who looked like she had eaten her fill, his chakra was still too much for Hanabi at the moment. Just a couple of bites had already left her dizzy.
Hyuga Hiashi, who had been guarding the door, immediately stepped forward to check on his daughter.
Breakfast had naturally been left to Hyuga Ayako and Hyuga Natsu to prepare. As someone who had never stepped into the kitchen, he would only cause trouble if he went.
"Hinata… hm?"
Hyuga Hiashi had originally wanted to ask whether Hinata still felt any discomfort, but when she looked toward him, his whole body suddenly seemed to feel some kind of pressure, and he instinctively paused.
Only then did he notice that within Hinata's clear Byakugan, faint light blue specks were flickering. These tiny points of light were weak and subtle, hard to notice.
But for him, they were easy to see.
This was also because Hinata's eyes had not yet fully evolved into the Tenseigan, making them difficult to control.
"Father."
"Hinata, your eyes…"
As if realizing something, Hyuga Hiashi's breathing grew noticeably heavier.
"Ahem! Uncle Hiashi, let's talk while eating."
Aoba reminded from the side.
"Ah! Right. You haven't had breakfast yet. Hinata, you must be hungry. Let's eat first. Ayako and Natsu have already prepared breakfast."
Hyuga Hiashi also realized his reaction had been a bit excessive and quickly calmed his breathing.
"Mm."
After hearing this, Hinata nodded, her face slightly flushed.
After replenishing so much chakra just now, she actually wasn't that hungry anymore.
But eating a normal portion of breakfast shouldn't be a problem.
———
"Aoba, Hinata's eyes… could it be what you mentioned last time?"
At the dining table, not long after sitting down, Hyuga Hiashi couldn't help but ask again.
Aoba had previously explained to him about the evolution of the Byakugan.
Looking at it this way, it wasn't strange that he couldn't wait.
After all, the evolution of the Byakugan was something that had only happened once in the thousand-year history of the Hyuga clan.
Hinata alone could have an entire separate page written for her in the clan genealogy.
"Mm. Hinata's eyes have taken the first step toward evolving into the Tenseigan, but it's not very stable yet. There's still a risk of regression."
Aoba answered calmly while holding little Hanabi in his lap, occasionally feeding her.
He had already eaten breakfast, so he didn't eat much himself. Most of the time, he was feeding her.
Come to think of it, Hanabi was about to graduate from the ninja academy.
In another two years, she probably wouldn't be able to sit in his lap anymore.
Time really passed quickly.
Hinata really wanted to tell Hanabi not to disturb Aoba while he was talking about serious matters, but seeing that Aoba himself didn't mind, she didn't say anything.
Of course, that only applied for now. If Hanabi were a bit older, then no matter what, it wouldn't be allowed.
As for Hyuga Hiashi, he had already grown used to the sight of his elder daughter sitting close beside Aoba, and his younger daughter even sitting on him.
Although it made his teeth itch a bit to watch, there was nothing he could do, so he continued asking about the important matter.
"Then… Aoba, do you have any way to stabilize Hinata's eyes?"
"Yes."
Aoba nodded calmly and continued, "I'll take Hinata somewhere later. At that place, her eyes can fully evolve."
"Where?"
Hyuga Hiashi asked, a bit curious.
Aoba didn't hide it.
"The moon."
