Initially, Naruto may not fully understand Fem Kyuubi's intentions. However, as Fem Kyuubi helps him control his chakra better and shows him new abilities, trust begins to build. She may share her past experiences with Naruto, which deepens their connection. As Naruto faces difficulties in the ninja world, Fem Kyuubi stands by his side, further strengthening their bond. Their relationship evolves from a somewhat tentative one to a strong, unbreakable bond. Fem Kyuubi becomes not only a mentor but also a confidant for Naruto, and Naruto becomes someone Fem Kyuubi is deeply invested in, seeing him as a symbol of hope and change in the Naruto world.
At first, Naruto might be scared or wary of Fem Kyuubi. But as time passes, he starts to see her as a protector. She teaches him about his own power and the secrets of the chakra. Their relationship becomes more of a student - teacher one. Then gradually, it turns into a deep bond like a mother - son relationship. Fem Kyuubi starts to care for Naruto not just as a vessel but as a person she has a connection with.
In the beginning, Naruto is likely to be confused by Fem Kyuubi's presence. She is a new and powerful force in his life. As she begins to teach him, he starts to respect her. This respect grows into admiration as he sees the extent of her knowledge and power. Over time, the relationship becomes very affectionate. Fem Kyuubi might start to show maternal instincts towards Naruto, and Naruto in turn, looks up to her as a source of strength and love. They become inseparable, with Naruto relying on her for guidance and Fem Kyuubi being proud of Naruto's growth.
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, 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 the beginning, it might be a strange and unexpected connection. But as they spend more time together, it turns into a deep emotional bond. Naruto's kind heart might make the fem Kyuubi feel things she's never felt before, and she starts to change for the better.
At first, Naruto might be a bit scared or hesitant. But as the fem Kyuubi shows her caring side, like protecting him from danger, Naruto starts to trust her. As time goes on, they become more like family. The fem Kyuubi shares her wisdom with Naruto, and Naruto in turn shows her the value of human emotions.
In this type of fanfiction, the fem Kyuubi's possessiveness might be manifested in her protecting Naruto at all costs. She could be overly vigilant and not allow any harm to come near him. This could lead to her interfering in battles or situations where Naruto might be in danger, even if he doesn't necessarily need her help all the time. She may also try to monopolize his time, not wanting him to go on missions with other people or make new friends. Her possessiveness could also be expressed in a more emotional way, like getting sulky or angry when Naruto doesn't pay enough attention to her.
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.
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.
There could be a fanfiction where Fem Naruto discovers a hidden side of Fem Kyuubi. Maybe Fem Kyuubi has some memories or powers that were locked away and Fem Naruto helps her unlock them. This could set off a chain of events that not only changes the relationship between them but also has a major impact on the entire ninja world as they face new threats and opportunities together.
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.
