She benefits from his combat knowledge. Kakashi is a highly skilled ninja, and he can teach Sakura new jutsu and fighting techniques. For instance, he could teach her some of his lightning - style jutsu, which would add a new dimension to her fighting style.
A frequent theme is the inheritance of Kakashi's knowledge. Sakura may learn his unique combat styles, his way of thinking in battle, and even some of his ninja philosophies. Also, the theme of self - discovery for Sakura is often present. As she trains with Kakashi, she discovers new aspects of herself, like her untapped potential in areas she didn't expect.
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.
One possibility could be that Sakura, under Kakashi's tutelage, further hones her medical ninjutsu skills. Kakashi, with his vast experience, might teach her some unique combat strategies that combine her medical skills with offensive moves. For example, she could learn to use her chakra scalpel in more creative and unexpected ways during battles.
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.
One interesting fanfiction could be 'Sakura's Training Days'. In this, Kakashi takes Sakura under his wing and really hones her skills. Sakura starts to learn not just physical jutsu but also how to strategize better, much like Kakashi. It shows their relationship growing as mentor and apprentice, with Sakura slowly becoming more confident and skilled under Kakashi's guidance.
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.
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.
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.
Well, Naruto might become more like Kakashi in terms of his combat style. He could start using more strategic moves rather than relying solely on his brute strength. This would make him a more well - rounded ninja.
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.
