Obviously, the fem demon kyuubi and Naruto are the key characters. The fem demon kyuubi is the one with the power and control in this scenario. Naruto is the one being 'owned', so his struggle against this situation is central to the story.
Well, in such a fanfiction, a possible main plot development could be the fem demon kyuubi using her powers to control Naruto in some way. Maybe she wants to use him for her own goals, like getting access to some hidden power within him. It could also involve Naruto trying to break free from her control and regain his own agency.
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.
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.
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.
In many fanfictions, Fem Naruto might show kindness towards the Kyuubi. This kindness could be something the Kyuubi has never experienced before. For example, instead of just seeing it as a source of power, Fem Naruto might try to understand the Kyuubi's past and pain. This could lead to the Kyuubi gradually opening up to her and them developing a deeper bond.
A plot could be that Fem Naruto and Fem Kyuubi have to go on a journey to find a special artifact. Along the way, they face various enemies and obstacles. They rely on each other's skills, with Naruto using her ninja techniques and Kyuubi her powerful chakra. This journey could also be a self - discovery for both of them, learning more about their true selves and their place in the world.
In Naruto fanfiction, the idea of a female Kyuubi and Fem Bjiuux can bring a fresh take on the story. It could explore new power dynamics and relationships. For example, their interactions with Naruto might be different from the original male - oriented ones. Maybe they could form a more sisterly bond with Naruto, adding a new layer of emotional depth to the story.
