At first, Futa Naruto could be scared or confused by the female Kyuubi. However, as he gets to know her personality (which might be different from the regular Kyuubi), he starts to develop feelings of friendship. Maybe the female Kyuubi shows a more nurturing side, helping Naruto when he is injured in battle. This kindness makes Naruto see her as more than just a source of power, and their relationship evolves from there.
It could start with curiosity. Fem Naruto might be curious about the power and mystery of Futa Kyuubi. As she gets closer, she realizes that Futa Kyuubi has its own personality and desires. They then start to communicate more, which builds the foundation of their relationship.
The relationship can be developed through shared experiences. For example, when they face a common enemy together. During battles, they can learn to trust each other's instincts and powers. Naruto's futa form might have some unique abilities that complement the Kyuubi's power, and as they use these in unison, their bond grows.
At first, it might be a relationship of mutual suspicion. Naruto is used to seeing Kyuubi as a source of power but also a potential threat. As the story progresses, they start to understand each other more. For example, through shared experiences in battles.
In such fanfiction, their relationship often develops through mutual respect. Naruto no longer sees Kyuubi just as a source of power but as a friend. Kyuubi, in turn, starts to value Naruto's determination and kindness. They might have heart - to - heart conversations in Naruto's mindscape, sharing their past traumas and hopes for the future.
The relationship development can also be influenced by external factors. If the village starts to view Naruto's connection with the Kyuubi in a more positive light, it can ease the tension between them. This allows for more open communication and deeper training sessions. Eventually, they might reach a point where they are like comrades, fighting side by side not just physically but also in terms of their shared goals for the village and the ninja world.
Often, the relationship development begins with Kyuubi being a menacing presence in Naruto's mind. However, as time passes, Naruto's determination and the fact that he is just a baby stir something in Kyuubi. Kyuubi might start to see Naruto as a potential ally or even a friend in the long run. Maybe there are times when Naruto is in distress, like when he is ill or being bullied in the orphanage, and Kyuubi unconsciously sends some of its warm chakra to comfort Naruto. This act of kindness, even if it's involuntary at first, starts to change the dynamic between them.
At first, their relationship might be based on mutual need. Naruto, being the one who wants to right the wrong of her banishment, and the Fem Kyuubi, who may need someone to help her. As they spend more time together, they start to understand each other better. Naruto sees the Fem Kyuubi not just as a powerful being but as a sentient individual with feelings. The Fem Kyuubi, in turn, realizes that Naruto is different from the others who feared or hated her. This understanding gradually turns into a deeper emotional bond, which could develop into love over time.
At first, Naruto might be a bit scared or hesitant. But as the female Kyuubi shows her care and concern for him, he would start to trust her. They would gradually develop a mother - son type of relationship. The female Kyuubi could be strict at times to make Naruto a better shinobi, but also very loving.
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.
Typically, it starts with Naruto being surprised or even a bit scared of the Female Kyuubi at first. But as he gets to know her better, he realizes she has her own motives and feelings. Then they start to communicate more, which leads to a gradual trust - building process.
