Yoruha didn't dwell on the question.
After Kakashi brought Naruto and Sasuke back to Tazuna's house, he sought out Yoruha to understand what had happened to Naruto.
When Naruto had lost control earlier, Kakashi had been fighting Zabuza and hadn't noticed Naruto's condition.
Under the moonlight, the two of them sat on the balcony outside one of the rooms.
Yoruha spoke first.
"The seal inside Naruto has already begun to loosen. This time, when he lost control, two tails appeared."
"And even with just two tails, he put me under a lot of pressure. If another tail had appeared, I probably wouldn't have been able to suppress him."
That was Yoruha's own assessment.
Even with only two tails, Naruto had already made Yoruha feel a tremendous sense of danger. He could tell that if Naruto's tails reached three, he wouldn't be able to handle it.
Yoruha's mindset was similar to Hashirama Senju's — he only saw how powerful his opponent was, not how much of a threat he himself posed to them.
This time, Yoruha had subdued Naruto using a combined ninjutsu technique that consumed less than one-tenth of his chakra.
In truth, the combination of the Water Dragon Bullet and Lightning Release wasn't just enough to suppress a two-tailed Naruto — even a three-tailed one would've been restrained.
The Water Dragon Bullet was secondary; the real danger to a rampaging Naruto was Yoruha's Lightning Release.
His Lightning Release was completely different from that of ordinary shinobi — far more destructive and lethal.
Kakashi didn't know the full details, but he could sense how sinister and malevolent Naruto's chakra had been at that moment.
Clearly, Kakashi believed Yoruha's words.
"That's also why the Third Hokage entrusted Naruto to me," Kakashi said.
"After becoming a ninja, the chances of him losing control have grown much higher than before."
"Judging from the strength he showed today, I'm not sure I can suppress him anymore."
"Even though I have the Sharingan, I'm not of the Uchiha clan — my ability to restrain tailed beasts isn't that strong."
"If you hadn't intervened today, I really wouldn't have had many ways to calm Naruto down."
Yoruha replied,
"Once we're back in the village, you should study some sealing techniques, Kakashi-sensei. Since the Third Hokage entrusted Naruto to you, he'd surely be willing to provide you with seals that can suppress his rampages."
Kakashi let out a wry smile.
"It's not that easy. Do you really think learning sealing techniques is that simple?"
"Basic ones, maybe. But those that can seal a tailed beast? They're incredibly difficult."
"It's not that I haven't tried — but most of them are classified as forbidden techniques, and I simply couldn't master them."
"Besides, nearly all of Konoha's sealing arts for tailed beasts come from the Uzumaki clan."
"Most require Uzumaki blood to wield effectively. The Fourth Hokage only managed it because his wife was an Uzumaki."
"I studied them once, but I never managed to learn them."
Kakashi sighed helplessly. He truly had tried to learn Uzumaki sealing arts — being the Fourth Hokage's disciple, it was inevitable that Minato would teach him — but he hadn't succeeded.
It was just like the Flying Thunder God technique: several of Minato's guards had learned it too, but none had mastered it.
Kakashi was a genius, yes — but mainly in combat. When it came to sealing arts, his talent was limited. And sealing a tailed beast was among the hardest of all.
Yoruha was surprised.
"Even you couldn't learn it? Just how difficult is it, then?"
Kakashi sighed.
"It really is that hard. Besides, many of these techniques require Uzumaki blood to perform."
Yoruha thought for a moment — indeed, many Uzumaki seals relied on their unique bloodline.
Take the Adamantine Sealing Chains, for example.
That technique was truly formidable — thanks to it, the Nine-Tails had never once broken free from Kushina Uzumaki's control.
It wasn't just for sealing, either — it could also be used offensively.
During the Fourth Great Ninja War, Karin Uzumaki had used Adamantine Sealing Chains in a desperate burst of power to shatter a wooden giant's arm while saving Sasuke.
Before Minato sealed the Nine-Tails inside Naruto, Kushina had already used the same technique to completely restrain the beast — even while on the brink of death.
Its power was self-evident.
Of course, that jutsu was clearly bound to the Uzumaki bloodline — after all, only Kushina and Karin had ever used it.
There were other powerful sealing arts too, like the Reaper Death Seal, though that one could only be used once — and even if Kakashi knew it, Yoruha would never want to learn it.
Then Kakashi turned to Yoruha, a sudden thought crossing his mind.
>"Wait — just because I found it hard doesn't mean you would."
He recalled Yoruha's astonishing ninjutsu talent. Maybe he had a knack for learning sealing techniques too?
Yoruha blinked in surprise.
"What do you mean?"
Kakashi explained,
"I mean, if you have the talent for it, I can teach you. I still remember the principles clearly, even if I never mastered them."
Yoruha frowned slightly.
"But isn't that kind of sealing technique forbidden? Should someone like me — a genin — really be learning it?"
He wasn't worried about failing to learn it — rather, he was concerned it might cause trouble for Kakashi.
After all, sealing arts capable of restraining tailed beasts were top-level village secrets.
And Konoha's sealing arts mostly came from the Uzumaki clan — known throughout the ninja world for their unrivaled sealing prowess.
Even Killer Bee had once told Naruto that the seals on his body were far stronger than those on his own — proof of the Uzumaki clan's mastery.
It was, in fact, because of this very power that the Uzumaki clan had been destroyed.
Kakashi waved his hand.
"I trust you completely."
"I even taught you Chidori — if you can learn sealing techniques, we'll finally have a way to handle Naruto's condition."
Kakashi was completely confident in Yoruha.
He knew full well that Yoruha's current strength already surpassed his own — and yet, Yoruha remained utterly humble, without the slightest trace of arrogance.
Even Kakashi himself hadn't been that composed at Yoruha's age.
"It's settled then," Kakashi said with a smile. "Starting tomorrow, I'll teach you the sealing techniques I know. Several of them were personally taught to me by the Fourth Hokage — though, unfortunately, I never mastered them."
There was a hint of embarrassment in his tone.
For all his genius, sealing arts had never been his strong suit.
He could manage basic ones like the Evil Sealing Method, sure — but that was nothing compared to the Uzumaki clan's seals.
He couldn't even suppress Sasuke's cursed mark with it.
