It could make her more confident. With Kakashi's guidance, she would gain more skills and knowledge, which would boost her self - assurance in battles and in general ninja life.
Sakura might become more patient. Kakashi's training methods are likely to be challenging and require her to persevere. Through this process, she would develop more patience in achieving her goals.
Kakashi's training style, which is often strict and methodical, would likely make Naruto more disciplined. Naruto is usually a bit of a wild card, but under Kakashi's tutelage, he would have to follow a set routine and be more precise in his actions.
She might learn some advanced jutsu. For example, Kakashi could teach her his famous Chidori, which is a very powerful lightning - style jutsu. This would significantly enhance Sakura's combat abilities.
It could also have caused a rift between her and Kakashi. Sakura might start to resent him for not believing in her or giving her the proper training. This could affect the team dynamic. Maybe she would start to distance herself from the team and try to find her own path, which could lead to some interesting plot developments in the fanfiction. For instance, she could end up joining a different ninja squad temporarily to get the training she needs.
They would become more united as they are co - parenting. They would have to communicate more often about the child's upbringing, training, and future. Their relationship would likely become deeper and more complex as they share the joys and challenges of raising a child.
Another possibility is that Sakura would feel really down at first. But then, inspired by her love for Sasuke or her desire to protect her friends, she would pull herself together. She could approach other more approachable senior ninjas for advice on how to train without Kakashi's guidance. For example, she might go to Shizune, who could give her some basic medical - ninjutsu training tips that she could build on herself. And she could also practice her physical strength training on her own, like doing extra push - ups and running drills in the forest.
In this fanfiction scenario, Kakashi's failure might cause Sasuke to be more reckless. Sasuke, feeling let down, could go off on his own more often. Sakura, who might have relied on Kakashi to keep Sasuke in check, would then be left to try and deal with Sasuke on her own. This could put a lot of stress on their relationship. She might be more desperate to bring Sasuke back to the right path, but Sasuke could see her as being too pushy, all because of Kakashi's initial failure.
I'm not sure specifically which 'kakashi trains sakura fanfiction' is the best. But if you search on popular fanfic sites, you might find some. It could be interesting to see how different authors imagine Kakashi passing on his knowledge and skills to Sakura. Maybe in some, he's strict and in others, more lenient.
Sakura's character often develops in significant ways in these fanfictions. When she time - travels, she is usually forced to rely on her own wits and skills more than ever. For example, if she travels to a time before she had her advanced medical training, she might have to relearn basic medical techniques while also using her future knowledge to make improvements. This can make her more self - reliant. Also, her relationship with Kakashi can cause her to become more empathetic. If she sees Kakashi in a vulnerable state, she may learn to understand his pain and grow as a more compassionate person.
Kakashi's laid - back yet effective teaching style would likely make Sakura more relaxed in her learning process. She would be less stressed compared to when she was under strict instructors. For example, Kakashi might use practical examples from his own missions to teach Sakura, which would make the learning more engaging.
Regular Kakashi and Sakura fanfiction usually focuses on their relationship in a more general sense, like friendship or mentorship. But 'hard lemon' fanfiction (if we assume it's not inappropriate) might explore more intense emotions or situations between them, perhaps more romantic or even angsty scenarios that are not typically explored in the regular ones.
