The mental aspect of his training could also be different. Having all of Kurama sealed within him might put more strain on his mind. So, his training could include more mental fortitude exercises. He might need to learn how to deal with Kurama's full - fledged influence on his thoughts and emotions, which could be much more intense compared to the original situation where only part of Kurama was initially accessible.
In terms of physical training, Naruto would need to train his body to withstand the greater power of both Kurama halves. He could do more strenuous exercises like lifting extremely heavy weights or running at high speeds for long distances while in a Kurama - enhanced state. Also, his mental training would be crucial. He would need to be mentally strong to handle the influence of both Kurama halves on his mind and to be able to access their power when needed without losing control.
Perhaps Naruto's relationship with the other villagers changes more rapidly. In the original story, they were initially afraid of him because of Kurama. But with all of Kurama sealed in him from the start, they might be more in awe or more fearful, which could lead to different interactions. He might also have a different standing among the ninja in his village, being seen as a more immediate and powerful asset or threat, depending on how they view the power of Kurama.
In the original Naruto story, the training is more in line with the established ninja academy and traditional Sensei - student relationships. But in 'naruto training lemon fanfic', it might be more experimental. Maybe Naruto tries some unorthodox methods of training that are not seen in the original.
Well, Naruto's power would be severely reduced. Kurama was a huge source of his chakra and strength. Without Kurama's power, Naruto would have to rely more on his own natural abilities and the skills he has learned over the years. He might become more like his early self, having to strategize and train harder to face strong opponents.
His training would likely incorporate more swordplay. Since Sakumo was a master swordsman, Naruto would probably start training with swords at an earlier stage. He might also be taught some of Sakumo's signature moves, which could be very different from the regular ninjutsu he's used to.
Well, it could be about a high - tech world where Naruto has a mecha version of Kurama. Maybe the plot involves fighting new and powerful enemies that can only be defeated with the combined strength of Naruto and his mecha Kurama. The fanfic could also explore how Naruto bonds with this mechanical version of Kurama, different from his connection with the original Kurama.
For Naruto, it would be a whole new experience. He'd be constantly trying to communicate with the mecha Kurama, learning its quirks. Shikamaru might be the one thinking about the strategic uses of mecha Kurama in battle. He'd be coming up with plans on how to best utilize it. As for Kurama, he could be in an internal struggle. Part of him would want to stay relevant in Naruto's battles, while another part would be curious about this new mechanical version of himself and how it could help Naruto in the long run.
His ninja skills would be different in several ways. Firstly, his chakra control would be more advanced as Kurama could guide him from an early age. He'd probably have a more natural affinity for using the Nine - Tails' chakra in combat. His stealth skills might be lacking since Kurama isn't exactly known for being stealthy. And his taijutsu would likely be more brute - force based, taking advantage of his enhanced strength from Kurama.
Well, Kurama could introduce Naruto to some new jutsu that are more in line with Kurama's own power. Maybe Naruto starts using more shadow - clone - based attacks in a different way. Instead of just creating a bunch of clones for distraction, he could use them in combination with Kurama's chakra to perform a more complex and powerful attack strategy. This would change his fighting style from a more straightforward one to a more strategic and powerful one.
In the fanfic, Naruto's training might be more intense and rushed. Since he graduates early, he may not have had as much time for basic training. So, he could be learning advanced jutsu before he has a solid foundation in the basics. For example, he might start learning more powerful Rasengan variations earlier.
