A good start could be from the perspective of the fem Kyuubi. We could see her watching Naruto from afar, admiring his strength and spirit. She then decides to make herself known to him in a non - threatening way. She could appear as a beautiful, mysterious woman in the forest where Naruto often trains. This would immediately grab Naruto's attention and start the relationship on an interesting note.
The fanfiction might begin with a change in the Kyuubi's chakra within Naruto. He starts to notice strange sensations and dreams. In these dreams, he sees a female figure that he later realizes is the fem Kyuubi. She starts to communicate her feelings to him in these dreamscapes, setting the stage for the rest of the story. This would be a great way to introduce the concept gradually and build mystery.
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.
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.
It could start with an unexpected encounter. Maybe Naruto is in a dangerous situation and the fem Kyuubi saves him in a way that no one else could. During this encounter, she realizes that he has a special quality that attracts her. And then, without much warning, she decides that he will be her mate.
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.
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.
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.
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.
Another way could be through communication. In some private moments, she might open up to Naruto about how she feels. She could say things like 'You are important to me, and I want you by my side always' in a soft and sincere tone.
The fem Kyuubi could also be protective in a more subtle way. Maybe she gives Naruto advice based on her long - time existence and knowledge. Like warning him about certain dangerous jutsus or shinobi he should avoid. She uses her wisdom to keep Naruto out of harm's way.
One popular 'naruto fem kyuubi mate fanfiction' is 'The Kyuubi's Female Bond'. It has an interesting plot where the female Kyuubi forms a unique bond with Naruto. Another could be 'Fem Kyuubi's Mate in Konoha' which explores their relationship within the village setting.
