For Naruto, his mental state would be the driving force for his development. If he's insane, he might initially lash out at the Fem Kyuubi or those around him. But as he interacts more with the Fem Kyuubi, he could start to see things from a different perspective. The Fem Kyuubi might develop by having to adapt to Naruto's instability. She could learn new ways to communicate with him and help him, which in turn would change her own character. For example, she might become more patient and understanding, which is a big change from her more traditional portrayal.
In this fanfiction, Naruto's development would be a rollercoaster. His mental insanity would cause him to make decisions that are out of character. He could go from being a hero - like figure in his own mind to a lost soul, depending on how his relationship with the Fem Kyuubi unfolds. The Fem Kyuubi would develop as she tries to guide Naruto back to some form of sanity. She might have to dig deep into her own nature and find new ways to connect with him. This could involve her showing him memories or emotions that she has, which in turn would also change her understanding of herself and her relationship with Naruto.
Naruto, with his mental insanity, would likely develop in a very erratic way. His actions might be unpredictable as he tries to come to terms with his own mind and the presence of the Fem Kyuubi. The Fem Kyuubi, on the other hand, could start off as a more stable entity but gradually be influenced by Naruto's insanity. Maybe she becomes more empathetic towards his situation.
One possible plot twist could be that Naruto's mental instability causes him to misinterpret the Fem Kyuubi's intentions. Maybe he sees her as a threat when she's actually trying to help him. This could lead to a lot of internal conflict within Naruto and also create tension in their relationship.
The fem Kyuubi could be initially attracted to Naruto's struggle with the Kyuubi inside him. She decides to help him. As Naruto's mental state improves due to her efforts, they could develop a romantic relationship. For example, she could teach him how to better control the Kyuubi's chakra, and in the process, they fall in love.
The relationships could develop gradually. At first, Naruto might be a bit wary of the Fem Kyuubi and Fem Bijuu because they are so different from what he's used to. But as they fight together against common enemies, a sense of trust could start to form. For example, if they save each other's lives in battle, that would strengthen their bond.
For Fem Naruto, her character development could be centered around acceptance. Accepting her own power, accepting Kyuubi, and being accepted by the village. Her relationship with Fem Kyuubi would be a catalyst for this. She would become more confident and less afraid to show her true self. Fem Kyuubi's development would be about transformation. She was once a feared entity, but with Naruto, she would transform into a more loving and protective figure. This transformation would be gradual, through their shared experiences and the deepening of their bond.
Naruto would likely become a much darker and more brooding character. His once - bright and determined personality would be overshadowed by his hatred. The Fem Kyuubi, on the other hand, might develop a more protective side towards Naruto, seeing him as an ally in her own goals. She could also become more empathetic as she witnesses Naruto's struggle. Other characters in the story would have to react to this new Naruto. His friends would be shocked and try to bring him back, while his enemies might be both afraid and intrigued by this new, more dangerous Naruto.
Naruto, being consumed by hatred, would likely become more brooding and intense. The fem Kyuubi could start off as a mysterious figure but gradually develop into a more empathetic character as she gets closer to Naruto. She might help him grow out of his hatred by showing him different ways of looking at his past and the world around him.
Naruto's development would likely involve a loss of his moral compass. He would no longer hold the values he once did, such as loyalty and friendship. His relationships with his friends like Sasuke, Sakura, and Kakashi would be severely strained. They would try to reach out to him, but he would push them away. The Fem Kyuubi could develop into a more sympathetic character as she gets closer to Naruto. She might start to understand the human emotions she once scoffed at and use her new - found understanding to either further corrupt Naruto or to save him from himself. It all depends on how the author wants to play out their relationship.
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.
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.
