And since when is this improvement not available? XD. At no time was it said that he has low chakra or that his body resistance is not good. Most of Ashura's advantages revolve around chakra, nature chakra affinity and weird stuff like empathy. In fact, the Uzumakis are supposed to be his direct descendants, and thus, Naruto already had that by mere genetics. But even if you have the same genes as god or even if you have the greatest potential in the world, it won't do you any good if you spend your whole life being lazy or wasting your time. All talent has to come with hard work.

Naruto is catching up, please don't forget that Sasuke trained a lot since the massacre of his clan. I found it illogical that Naruto in a couple of months already surpassed him so easily.

He is a descendant of soul, but not of blood.

Oh, you're talking about Fuinjutsu, yes, I already have a lot planned for that but it's something we'll see more of in the future.

Loz uzumakis have their own traps, such as their large numbers of chakras. The problem here, was that Naruto having a strength similar to that of the current Sasuke, confronted him only using physical strength, and losing the process by the mere advantage of the sharingan.

In the original Kakashi knew of the danger and still continued for the same reasons.

And I didn't really understand your words, but what I did here, is that Naruto woke it up by mere instinct and its use was brief because of the great amount of stress that his body was suffering due to being fighting with everything physically. My idea is that as time goes by, his body will gradually get used to the Dojutsu.

I am making the change gradual, since even Ranmaru showed that his Dojutsu awakened between 6 to 10 years old approximately, and it is not something he has had since his first day of birth.

I doubt that Kakashi's sharingan control is mediocre, because although his potential was not used in the original story, it was not for nothing that he was called the one who copied a thousand techniques. The only thing he had problems with was the Mangekyo Sharingan, but with the normal Sharingan he often showed great mastery.

He already has a dojutsu that serves to counteract the sharingan, and as for the hand seals... I didn't really think they were useful because the way they were used in the original story, they seemed to be nothing more than crutches for skills you don't have control over. Let me investigate a little more on the subject and if I see it viable, in the future the seals will be added more.

As for your last question as to why there is so little talk with Kurama now, it is mostly to avoid suspicion, after all he has two Sharingan users around him and in the original story they were shown to have the ability to enter the seal and even sense what is going on inside, so I don't find it very smart to have conversations during these times.

If he knows about the lightning element, but it is obvious that it makes no sense to train him when he has not even mastered the wind element, and considering that he already has his hands full with his chakra control training and his body training, I think it is unnecessary and illogical to take something like the lightning element for now. As for Ranmaru's Dojutsu, it really showed itself for the first time in this fight, reread and you will understand.

I have many chapters of Reversal written, but between my studies and my work I don't have the time to translate and edit more than one novel. Like all the other novels, I really have about 50 more chapters written in each one, I just have time problems. But lately I've been focusing a lot on My Mother Is The Heavenly Demon and I plan to continue it.

Don't forget that information, I always kept it in mind. And actually the jutsu is not that complicated to learn as shown in the original, but it was banned because as you said, it takes up a lot of mental stamina and its extreme use can end up killing you. But despite this, in the story it was shown many times to other characters using them but in a smaller amount, always without making more than 10 clones or even less. I think it all comes down to the amount and the time you keep it active.

Did you read the labels before reading the novel? Clearly I added the Slice of Life tag, and in case you don't know what it means, it boils down to the fact that the novel will have a more significant focus on human interactions than on specific events.

Sasuke has been training like crazy all his life, not for nothing was he the best in the academy. Meanwhile, Naruto, with luck, has been training for a couple of months.

That's what I'm seeing. In many places they say that one tomoe is enough, in others they say two. But personally, I can't change it anymore xD.

If you can copy techniques with a tomoe, although it is more rudimentary and those that are slightly complex are obviously left out. The more tomoes, the more this copying ability simply increases the level of what you can copy.

Idk, when I wrote this I based it on the manga and anime, and I remember when I researched tsunami and the man the boy calls dad, he turned out to be a good man who helped the boy and they became attached to each other.

All training is error and correction. Just like trying to shoot at a target, the first few times you will hardly hit the target, but after hundreds of mistakes, your aim will improve considerably.
