Their relationship might become more of a strategic partnership. Naruto would respect Kurama's power and knowledge more deeply as they face the complex and dangerous ANBU missions together.
The relationship could start off with curiosity. Naruto's sisters might see Anbu Naruto around and be intrigued by his silent and efficient ways. They start to follow his movements from a distance. As time passes, they might find opportunities to interact, like when Anbu Naruto is injured and they offer help. This leads to more frequent meetings and conversations. Slowly, feelings of love start to develop as they get to know each other better.
Their relationship could become more competitive. Since ANBU is a place for elite ninjas, they might constantly strive to outdo each other in missions.
In terms of their relationship development, a female Kurama could bring out a different side of Naruto's personality. She might encourage Naruto to explore his more sensitive and empathetic side. This could lead to Naruto making different decisions in battles and in his relationships with other characters. For instance, he might be more likely to try to understand his enemies' motives rather than just fighting them head - on. Also, their bond could be more of a partnership based on mutual respect and shared emotions rather than just a power - based relationship like it was with the male Kurama at the start.
At first, it might be filled with suspicion. Naruto, being the Hokage, would be cautious of Itachi's past actions as an Anbu. But as they start to interact more, Naruto might see the good in Itachi that Sasuke saw. Itachi, on the other hand, would respect Naruto's position as Hokage and his power to bring change. Slowly, they could develop a mutual understanding and respect.
Naruto would become more confident. With Kurama's training, he'd know he has more power and skills at his disposal, so he'd face challenges with less hesitation.
Naruto's character would likely be more confident. Since Kurama is raising him, he would have access to Kurama's knowledge and power, which would make him feel more secure. He might not be as loud or desperate for attention as in the original series because he has Kurama's constant support.
In the 'Naruto adopted by ANBU' fanfiction, Naruto's character development could be quite different. He would be exposed to a much more intense and dangerous environment from a young age. This could make him more jaded and world - weary compared to his original self. On the other hand, the ANBU's training might also give him a greater sense of purpose and focus. He could become more of a lone wolf type, relying on his own skills and the training he received from the ANBU rather than the support of his friends initially. But as the story progresses, he might learn to combine the two aspects of his life - his ANBU training and his bonds with his friends - to become a stronger and more well - rounded character.
At first, they might be a bit suspicious of each other. Boruto has heard stories about Kurama but has never really interacted with him. Kurama, on the other hand, might be cautious as Boruto is Naruto's son and not sure if he can be trusted. But as they spend more time together, they could start to respect and rely on each other.
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.
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.
