Naruto: The Hima clan

Akio let out a heavy sigh before addressing Keiko, who was looking at him with a hint of fear in her eyes. "I apologize but you aren't supposed to see that," he muttered, his voice tense with emotion.

Sensing the tension in the air, Akio excused himself for a moment and formed the serpent sign with his hands.

"Denjutsu: Odayakanaumi (伝術: 穏やかな海, Domain Arts: Calm Sea),"

as he spoke, his chakra spread from his body to create a dome-like barrier around their tent. The barrier was invisible, making it undetectable to anyone outside.

"Now that we are in a soundproof domain, we can discuss what Keiko saw," Akio said, resting his hand on his knee as he looked at Kaito. Kaito, who had been using his Kagura eye to sense any chakra fluctuations in the area, was surprised to find none. If he hadn't witnessed Akio using the jutsu, he would have thought no chakra was used at all.

"What did you do?" Kaito asked, curiosity dancing in his eyes.

" just as I said before. I created a barrier where no one can hear our conversation," Akio replied, carefully rolling up the scroll that had been dropped on the floor and placing it by his side. "It's a type of jutsu that ensures our privacy."

"Kaito-San, I apologize for this request, but do you happen to possess any sealing jutsu that can erase memories?" Akio asks, looking at Kaito with a hint of desperation in his eyes. Kaito, already understanding the reason behind Akio's question, responds with a reassuring smile.

"I completely understand your dilemma. Keeping secrets like this is crucial, and I would not allow anyone else to know about it either," Kaito says, his gaze shifting towards a scroll placed beside Akio. However, before agreeing to help, Kaito adds a condition, meeting Akio's eyes with a serious expression.

"But, I have one condition. Can you explain to me the concept of 'all flames'? I know that the memory will be sealed afterwards, but I am curious and would like to satisfy my curiosity," Kaito states firmly.

Hearing this, Akio falls into deep thought. He is conflicted about whether or not to trust Kaito and the Uzumaki clan. Although they have been portrayed as trustworthy and kind-hearted in the anime, they are still ninjas, known for their deceiving tactics.

After much contemplation, Akio finally comes to a decision to trust Kaito. However, he also prepares a backup plan in case Kaito betrays his trust. "Okay, I will tell you about The All Flames," Akio says, looking at Keiko who had recovered from her earlier shock and was now listening intently.

"The All Flames is actually a theory," Akio states, noticing Kaito's curiosity.

"A theory?" Kaito asks, his curiosity already taken over him as he had already forgotten that all the knowledge he learns would soon be forgotten.

"Yes, a theory," Akio confirms, shifting his gaze to Kaito who was now fully attentive.

"I developed a hypothesis that there exists an ultimate flame - one that combines all the other flames: the soul flame, white flame, black flame, hell flame, sun flames, and more. This flame would be more powerful than the sun by leaps and bounds, capable of burning anything - from space to souls and even time, just like Keiko mentioned earlier. Nothing can extinguish this flame, and it will continue to burn endlessly. This flame is known as The All Flame, the one and only true flame."

"Wow, that jutsu is incredibly powerful," Kaito gasps, his eyes widening as he looks at the scroll beside Akio. He can now understand why Keiko was so afraid.

"But, it's not as simple as just using it," Akio explains with a hint of disappointment. "I currently lack the ability to enter sage mode at will, which is a crucial element for this jutsu to work. And on top of that, I need a huge amount of chakra, almost as much as a tail beast, to even attempt it. And let's not forget that I also need to immobilize my opponent beforehand, otherwise they could easily dodge the attack."

"Thank you for trusting me with such information, even though I would not remember it, it was worth knowing such a powerful justu in my lifetime" Kaito says smiling feeling elated to know such a jutsu even thouh he wouldn't be remembering it

And without wasting time Kaito turns to Keiko and places his hands on her head while forming seals with his other hands his hands movement fast fluid

"Fūinjutsu: Kioku no fūin (封印術:記憶の封印, Sealing Jutsu: memory sealing)"

After Kaito expertly completed a series of hand signs, intricate seals began to form on both his and Keiko's bodies. The seals then shrank and traveled to their heads, disappearing after 10 seconds. Kaito's eyes, which had been closed during the sealing process, opened to reveal a look of confusion. He felt a throbbing headache and couldn't remember what had just happened. Keiko, with her weaker mental abilities, was struggling even more to recall the events.

Kaito looked around, trying to make sense of his surroundings. However, a strange emptiness washed over him whenever he attempted to remember the previous moments.

Akio, who had been observing the sealing process, asked Kaito what he could remember. "What's the last thing you recall, Kaito-san?" Akio inquired, his gaze fixed on Kaito with hope that the jutsu had worked.

"Ummm, you were just explaining your new Denjutsu to me," Kaito replied, slowly recovering from his headache and piecing together what had transpired.

"Great, it looks like it worked." Akio mutters under is breath making sure his words aren't heard "What are your thoughts on the previous deal we were discussing?" Akio says with a sense of relief, grateful that the issue had been resolved without any further complications. He was relieved that he didn't have to resort to turning his guest into ashes.

"You mean, the deal where we agreed for you to create five S rank sealing jutsu's for us while we seal your scrolls," Kaito clarifies, his gaze fixed on Keiko, who had recovered from her headache but was still trying to piece together the missing memories.

"Yes, that's the one," Akio confirms, maintaining a composed poker face.

"Hmm, we accept the deal. However, I'll need to consult with my clan head first before finalizing anything. But I'm sure he'll be on board with this," Kaito responds, glancing back at Akio before noticing the untouched cup of tea on the stool.

"That's great news. Unfortunately, I won't be able to see you off as I have some urgent matters to attend to. But I wish you a safe journey," Akio politely apologizes, bowing to Kaito and Keiko as they also bow and leave the tent.

As Kaito and Keiko exit the tent, Akio lets out a heavy sigh, feeling drained and exhausted. "I was careless. I almost jeopardized my entire clan with my recklessness. I need to work on being more careful, or else I'll end up causing our downfall instead of helping us prosper."
