At first, there might be a misunderstanding between them. The fem demon foxes might mistake Naruto for someone who wants to harm them. But Naruto, through his actions of kindness and protection, clears up the misunderstanding. This makes the fem demon foxes feel guilty for misjudging him and they start to make amends, which is the start of a beautiful relationship.
Perhaps the fem demon foxes are cursed and Naruto, with his own experience of being an outcast, tries to break the curse. They form a bond during this process, and together they face challenges like dealing with the distrust of the Hidden Leaf Village.
Their relationship can be developed through shared experiences. For example, going on dangerous missions together. Each time they face a new threat, they learn more about each other's abilities and personalities. Naruto's positive attitude can slowly break down Fem Sasuke's more reserved nature.
To develop the relationship between Naruto and Fem Kobaoto in the fanfiction, it can begin with a chance encounter. For instance, Fem Kobaoto is in trouble and Naruto comes to her rescue. This initial act of heroism can make Fem Kobaoto see Naruto in a positive light. From there, they could be involved in a series of events that force them to spend more time together. They might attend a ninja festival together where they share some fun moments. As they interact more, they discover shared interests such as a love for a particular type of ramen. This discovery of commonalities can be the foundation for a deeper relationship. Also, as they face challenges together, like dealing with a powerful rogue ninja threatening the village, they rely on each other's strengths and their relationship evolves.
Their relationship can be developed through shared experiences. For example, when they face a powerful enemy together, Fem Naruto relying on Fem Kyubi's power and Fem Kyubi trusting Fem Naruto's skills. This mutual trust can deepen their bond.
The relationship can be developed through mutual respect. Naruto could respect the Fem Kyuubi's power and knowledge, and in return, she could respect his determination. For instance, they could start off as wary of each other but gradually learn to trust. They might share stories about their pasts, with Naruto talking about his lonely childhood and the Fem Kyuubi about her long existence. This sharing could create a connection between them.
In this fanfiction, perhaps Naruto is isolated from the human village. He might have a different view of the world compared to the original Naruto. The demon foxes could teach him their own form of ninjutsu, which is more primal and raw. This would lead to him having a very distinct fighting style when he finally interacts with other ninjas.
His character would be more feral. He'd be more in tune with his instincts like the demon foxes. So he might be quicker to anger and more impulsive in his actions.
In fanfiction, the relationship might start with curiosity. Kushina could be curious about Naruto's demon side. She starts to study it and in the process, gets closer to Naruto. As she helps him understand and control his powers better, they become friends. Then, as they spend more time together, they realize they have feelings for each other that go beyond friendship. They support each other through difficult times, like when Naruto has to face the negative aspects of his demonic form, and Kushina has problems in the village. This continuous support deepens their relationship.
Their relationship can start with mutual respect. Naruto, in his godlike form, respects the power of the Fem Kyuubi. The Fem Kyuubi, in turn, respects Naruto's newfound divinity. This respect can gradually turn into friendship as they fight side by side.
The relationship can start with mutual mistrust. Since the Kyuubi has a history of being feared, Naruto might be cautious at first. But as they interact more, they find common ground, like their shared love for the forest around the village. This simple shared interest can start to build a bond.
