It could be that Kurama's power goes out of control and accidentally turns Naruto into a fox girl. Naruto then has to search for a way to fix it. In the process, he might discover new aspects of Kurama's power. He could also meet some old enemies who don't recognize him in this new form and this could lead to some interesting encounters. Naruto would also have to deal with the cultural and social implications of being a fox girl in the ninja world, such as how he is treated differently by different clans.
Maybe it's a self - discovery plot. Naruto has always felt a special connection to the Nine - Tails. One day, due to some internal spiritual awakening, Naruto starts to transform into a fox girl. This transformation makes Naruto re - evaluate his identity. He starts to explore the more feminine side of his personality and the hidden powers that come with the fox girl form. Along the way, he also helps other characters in Konoha understand that there's more to a person than their physical appearance, and his new form becomes a symbol of acceptance and change in the village.
Well, perhaps Kurama has some special reason like protecting Naruto from a certain danger. Maybe Naruto as a wolf would have enhanced senses and could use his new form to spy on enemies or explore areas that are hard to reach as a human. He might also struggle to control his new wolf instincts at first.
Sakura might be really surprised at first. She could be a bit skeptical about whether it's really Naruto or some kind of trick. But then she would probably try to help him find a way to change back.
One plot could be that the girl is an outcast in her own village because of her strange ability to sense Kurama's presence from afar. When she finally meets Naruto, she helps him to better control Kurama's power. They train together, and the girl's unique insights into Kurama's nature allow Naruto to unlock new levels of his power.
In a 'naruto turns into a fox lemon fanfiction', it could be that Naruto is cursed by an enemy to turn into a fox, and the 'lemon' aspect could be symbolic. It might represent something sour in his new form, like he has a hard time controlling his instincts. He could be constantly fighting the urge to act more like a wild fox rather than his normal self, and this 'lemon - like' struggle is the main focus of the story.
One possible plot could be that Kurama, seeing Naruto in her female form, decides to give her a fox tail as a symbol of their unique bond. This could lead to Naruto having new powers or a deeper connection to the Nine - Tails' chakra. Maybe she can use the tail for balance in battle or even for some kind of new jutsu that involves the tail's movement.
One key element is the connection to Kurama. Since Kurama is such a powerful and important part of Naruto's world, in these fanfictions, the fox girl often has some sort of link to Kurama, whether it's through shared powers or a deeper spiritual bond.
One main theme is often friendship. Kurama, being a powerful and somewhat solitary being, and the fox - girl, who may be an outcast in the Naruto world, can form a strong bond of friendship. Another theme could be power and its implications. Their combined powers can be used for good or bad, depending on how the story is written.
One possible plot could be that Naruto's friends initially don't recognize him. Then Naruto has to find a way to communicate with them while in fox form. He might discover new abilities that come with being a fox, like enhanced speed or senses, and use these to his advantage in battles or to solve problems in the Hidden Leaf Village.
One possible plot is that Naruto, now a girl, enters a yuri - themed ninja tournament. There, she meets a powerful and beautiful female ninja. They start off as rivals but as they face each other in battles and training sessions, their relationship evolves into something more. Naruto's new - found femininity could add a whole new dynamic to their interactions.
