Yes, there are likely fanfictions with such a concept. The idea of a 'godlike' Naruto trained by the female Kyuubi is an interesting and popular concept in the Naruto fanfiction community. It allows for unique storylines and character developments.
The training by the fem Kyuubi could also change Naruto's view of the world. He might start to see the tailed beasts in a new light, not just as powerful and dangerous entities but as beings with their own personalities and stories. This could potentially lead to him trying to bridge the gap between humans and tailed beasts in the fanfiction world.
One possible plot could be that Naruto starts off as his normal self but as he is trained by the fem Kyuubi, he gradually gains godlike powers. He then uses these powers to protect Konoha from a new, powerful threat.
Naruto would probably become more empathetic. Since the fem Kyuubi has her own unique perspective, Naruto would be exposed to different ways of thinking. This could make him better at understanding others' feelings.
There could be a fanfiction where Fem Naruto discovers a hidden side of Fem Kyuubi. Maybe Fem Kyuubi has some memories or powers that were locked away and Fem Naruto helps her unlock them. This could set off a chain of events that not only changes the relationship between them but also has a major impact on the entire ninja world as they face new threats and opportunities together.
It could be an original character created by the fanfiction author. This character might be a descendant of the original Kyuubi, but with a female form and her own distinct personality.
I really liked 'Fem Kyuubi's Bond with Naruto'. In this fanfic, the fem Kyuubi forms a deep emotional bond with Naruto. The author does a great job of showing how they support each other through various challenges. It has some really cool fight scenes where the fem Kyuubi's unique abilities are shown, which makes for an exciting read.
One great fem Naruto x fem Kyuubi fanfiction could be one that focuses on their unique bond. It might explore how they interact in a world where Naruto is female and the Kyuubi also takes a female form. For example, it could show them teaming up against common enemies and how their combined powers are different from the original story.
Well, in such a fanfiction, it might be that Naruto becomes extremely powerful like a god. Since he is trained by the Kyuubi, he could gain unique powers and abilities. Maybe he masters the Kyuubi's chakra in ways no one else has. He could use this power to defeat powerful enemies, protect his village in extraordinary ways, and perhaps change the entire shinobi world with his new - found god - like strength.
In this type of fanfiction, the fem Kyuubi's possessiveness might be manifested in her protecting Naruto at all costs. She could be overly vigilant and not allow any harm to come near him. This could lead to her interfering in battles or situations where Naruto might be in danger, even if he doesn't necessarily need her help all the time. She may also try to monopolize his time, not wanting him to go on missions with other people or make new friends. Her possessiveness could also be expressed in a more emotional way, like getting sulky or angry when Naruto doesn't pay enough attention to her.
