One way is through shared experiences. If they are both put in a situation where they are in danger, like being trapped in a genjutsu together. They have to work together to break free. This would force them to communicate and rely on each other. Also, the male Kyuubi could start to see Naruto's dreams of peace and be influenced by them. He might then start to support Naruto more actively in his pursuits.
It re - imagines it as a more complex relationship. Instead of just being a host and a tailed beast, Naruto has to deal with Kyuubi as a slave, which adds a whole new layer of moral and emotional complexity.
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.
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.
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.
Their relationship could start with mutual understanding. Naruto, who has always had a connection to the Kyuubi, now with a female form, could start to see her as more than just the beast inside him. They could have conversations about his dreams and her past.
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.
Their relationship could also grow through mutual respect. The female Kyuubi respects Naruto's strength and determination, and Naruto respects her power and the fact that she has been trapped for so long. This respect can lead to a friendship or even something more as they rely on each other more and more in difficult situations.
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.
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.
There could also be a romantic relationship in some fanfics. This would bring a whole new dynamic to the Naruto universe. It might start with small moments of mutual understanding and attraction, gradually evolving into a full - fledged love story. However, this would also face many challenges, like the differences in their nature (human vs. tailed beast) and the opinions of others in the ninja world.
