One way is through shared experiences. For example, they could go on a journey together outside the village. During this journey, they face challenges like bad weather, lack of food, and dangerous animals. As they overcome these challenges together, their bond grows stronger. Also, Naruto could introduce Kurama to his friends, and Kurama could learn to interact with humans in a more friendly way. This would show that their relationship is not just about being sealed together but about true friendship.
To develop their relationship in fanfiction, one approach could be to give the female Kurama a backstory that makes her more relatable to Naruto. Say she was once a normal fox in the forest before being transformed into a powerful being. Naruto, with his kind heart, would be sympathetic to her situation. They could also have moments of cultural exchange. Naruto could teach her about human traditions, and she could share with him the ancient knowledge of the fox spirits. This exchange of ideas and experiences would help build a strong relationship between them. Moreover, having them face internal conflicts together, like Naruto's struggle with his own power and the female Kurama's identity crisis, would also strengthen their bond as they support each other through these tough times.
It might be portrayed as a very strong and almost spiritual connection. They could be shown as two halves of a whole, with Naruto relying on Kurama not just for power but also for emotional support and vice versa.
To develop their relationship in the fanfiction, start with small acts of kindness. Naruto could bring Kurama some food from the human world that he thinks Kurama might like. Then, gradually build up to more significant events. Let them protect each other. For example, when Naruto is in danger, Kurama could use his own power in a new way to save him. And vice versa. Also, introduce some external factors that force them to rely more on each other, like a prophecy that says only their combined efforts can save the ninja world. This would make them realize the importance of their bond even more and deepen their relationship as brothers.
Their relationship could be developed further through mutual understanding. For example, Naruto could learn more about Kurama's past and the reasons for his anger and hostility in the beginning. This would make Naruto more empathetic towards Kurama, and Kurama in turn could start to trust Naruto even more.
As Kurama teaches Naruto seals, they develop a sort of teacher - student bond. Naruto respects Kurama's wisdom, and Kurama in turn respects Naruto's determination to learn. This bond might lead to them having more in - depth conversations about the nature of chakra, the history of sealing techniques, and even their own pasts. For example, Kurama might share stories about how certain seals were created in the ancient times and how they were used in battles. Naruto, on the other hand, might tell Kurama about his dreams for the future of the ninja world and how he plans to use these new sealing techniques to bring peace. Through these exchanges, their relationship becomes more complex and multi - faceted.
Some of his friends, like Sasuke, could see this merge as a new opportunity for Naruto to grow even stronger and might encourage him to explore his new powers further. On the other hand, some friends like Sakura might be more concerned about Naruto's well - being and worry that the merge could have negative effects on his mental or physical state.
The relationship could be developed through shared dreams. Every night, Naruto and Kurama enter a dreamscape where they can communicate freely without the interference of the outside world. In these dreams, they gradually open up to each other about their past traumas. For Naruto, it could be about his loneliness as a child, and for Kurama, it could be about his long - held resentment towards humans. Through this sharing, they grow closer.
One unique way to develop their relationship is through art. In the fanfiction, Naruto could have the ability to draw out Kurama's chakra in a new form using his own creativity. This would be a new way of interacting that combines Naruto's love for art and his connection to Kurama. As they explore this new form of chakra manipulation together, their bond deepens.
A really unique way to develop their relationship is to have them swap abilities for a short period. Naruto gets some of Kurama's fox - like abilities and Kurama gets some of Naruto's human abilities. This forces them to understand each other's perspectives in a whole new way. They have to learn how to use these new abilities and in the process, they become closer. Another aspect could be that they are both transported to a parallel dimension where they are the only ones who know each other. They have to rely solely on each other to survive and find a way back home, which would greatly enhance their relationship.
The relationship might also develop due to external factors. For example, if the Hidden Leaf Village is in danger and Naruto has to rely on Kurama's power more than ever. Kurama, seeing Naruto's determination to protect his home, decides to fully cooperate and they end up having a stronger connection as a result of this crisis.
