At first, the relationship might be based on mutual benefit. The fem Kyuubi might see Naruto's mercenary skills as useful for her own goals, and Naruto might see her power as an asset. As time goes on, they could develop a deeper emotional bond. They might start to understand each other's pasts and traumas, which would bring them closer together.
The relationship could develop in a very complex way. Given Naruto's role as a mercenary, he might be hesitant to get too involved with the fem Kyuubi. However, if she shows a side of herself that is vulnerable or in need of protection, Naruto's natural heroic instincts could kick in. On the other hand, the fem Kyuubi could teach Naruto things about the world that he didn't know as a mercenary, and this exchange of knowledge and experience could strengthen their relationship.
At first, their relationship might be one of mistrust. Naruto is wary of the Kyuubi as he's always been taught to fear it. But the female Kyuubi, being different in this fanfiction, tries to reach out to him. Slowly, they start to understand each other. Naruto sees that she's not like the stories he's heard.
The development of their relationship would be full of twists and turns. Naruto is a hero, and the fem Kyuubi is a powerful entity. In the female world, social dynamics might be different. Naruto could initially be confused by the fem Kyuubi's presence and her femininity. But as he gets to know her better, he'll realize that she's not so different from the Kyuubi he knew in some ways. They could start to trust each other gradually. For example, they might team up to face challenges in the female world together, which would strengthen their bond over time.
Their relationship might start with Naruto being curious about the fem Kyuubi. He's used to the regular Kyuubi, but this new, female form is different. As he gets to know her, he discovers she has a softer side. And she, in turn, starts to see Naruto not as just a powerful being but as someone with a kind heart.
At first, their relationship might be full of tension. The cold Naruto is likely to be guarded, and the Fem Kyuubi may be wary of his intentions. But as time passes, they could start to understand each other's loneliness. Naruto's cold exterior might soften as he realizes the Fem Kyuubi also has feelings and desires.
The relationship between Naruto and the fem werewolf could start as a friendship based on mutual respect for each other's abilities. Naruto would be intrigued by her werewolf powers. With the fem Kyuubi, Naruto already has a complex relationship due to the Kyuubi inside him. As the story progresses, the fem werewolf might develop romantic feelings for Naruto, which could make the fem Kyuubi a bit envious at first. But eventually, they could all form a strong, platonic bond where they support each other in different ways, like in battles or in dealing with the politics of the Hidden Leaf.
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.
The female Kyuubi might start with a relationship of distrust towards Naruto. After all, the Kyuubi has a long history of being feared and hunted. But as Naruto shows her kindness and understanding, she could gradually warm up to him. The female Juubi, being a more mysterious and powerful being, might be initially indifferent to Naruto. However, when she sees his determination and the good in him, she starts to respect him. Their relationships would develop through shared battles and experiences, with Naruto constantly proving himself to be a worthy ally and friend.
The relationships could develop in a very complex way. Fem Amaterasu might initially be aloof because of her divine nature. However, Naruto's tenacity and his own special powers would draw her in. Fem Kyuubi, having a more primal connection to Naruto already, would further strengthen that bond. As they go on adventures together, Naruto would often be the mediator between Fem Amaterasu and Fem Kyuubi. Their different personalities would clash at times, but through Naruto's influence, they would learn to work together and eventually form a strong and loving relationship with Naruto at the center.
Some writers develop their relationship by exploring their mental connection. Since Naruto has a connection to the Kyuubi from the start, when it's a fem version, this connection can be deepened and explored in new ways. They might be able to communicate telepathically and share emotions. This leads to a more intimate bond. Also, the Fem Kyuubi might teach Naruto new jutsu or skills, which is a form of bonding as Naruto becomes more powerful with her help and they grow closer through the learning process.
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.
