Well, it could be that Fem Naruto has to prove herself to Fem Kyuubi. Maybe there's a prophecy or something that says only by uniting with Kyuubi can Naruto save the village in a new and greater threat. So, Naruto embarks on a journey to understand Kyuubi better. Along the way, they have adventures, meet new characters. Kyuubi starts to respect Naruto for her tenacity and Naruto admires Kyuubi's power. Their relationship evolves and eventually leads to them becoming mates, which also brings about a new era of peace and understanding in the village.
In a 'naruto is fem kyuubi's mate' fanfiction, perhaps the story begins with Naruto being drawn to the Kyuubi's chakra in a way he doesn't understand at first. The fem Kyuubi, on the other hand, is intrigued by Naruto's determination and spirit. As the story progresses, they form a bond that goes beyond the normal host - tailed beast relationship. They might have to deal with the reactions of the villagers who are either afraid or in awe of this new development. And together, they embark on a journey to bring a new kind of peace to the ninja world, one that is based on the unity of their unique relationship.
Yes, there are likely fanfictions out there with this concept. The Naruto fandom is quite large and diverse, so many creative and unique ideas get explored in fan - made stories. However, the quality and content can vary greatly from one to another.
For Fem Naruto, her character development could be centered around acceptance. Accepting her own power, accepting Kyuubi, and being accepted by the village. Her relationship with Fem Kyuubi would be a catalyst for this. She would become more confident and less afraid to show her true self. Fem Kyuubi's development would be about transformation. She was once a feared entity, but with Naruto, she would transform into a more loving and protective figure. This transformation would be gradual, through their shared experiences and the deepening of their bond.
One common theme is power and how the combined power of Naruto and the fem kyuubi is used. Another is acceptance, as Naruto has to accept the fem kyuubi as his mate and vice versa.
One idea could be that the fem Kyuubi starts to show her affection in small ways. For example, she might protect Naruto more fiercely during battles. She could also start leaving little signs of her presence around him, like a soft growl when danger is near that only he can hear. This would build an interesting dynamic as Naruto tries to figure out what these new behaviors mean.
Well, one possible plot development could be that at first Naruto is completely shocked. He has always seen the Kyuubi as a powerful and somewhat menacing force. But as the story progresses, he starts to understand the fem Kyuubi's perspective. Maybe she has been alone for a long time and sees Naruto's strength and kind heart as qualities that would make him a great mate. They could then start to develop a relationship where Naruto teaches her about the human world and she in turn shares her ancient knowledge with him.
The plot might involve Naruto being in a life - threatening situation where the fem Kyuubi saves him. This act of heroism makes Naruto see her in a new light. They start spending time together, and Naruto begins to learn about the fem Kyuubi's past and her own struggles. As a result, he feels a strong connection to her. Over time, their relationship blossoms, and they become mates. Along the way, they might face opposition from some in the ninja world who don't understand or accept their relationship.
One possible plotline could be the two characters starting as enemies or at least with a lot of misunderstandings. As the story progresses, they gradually come to understand and trust each other, and a romantic relationship begins to form.
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 also be for revenge. Naruto might have unknowingly done something that offended fem Kyuubi in the context of this fanfiction. For example, he could have disrupted her plans or made an enemy of someone she cared about. So, trapping him in a henge is her way of getting back at him.
