How would Naruto and Kurama's relationship change if they go back in time in fanfiction?

In the past, their relationship could be more complex. Kakashi might be suspicious of Naruto's sudden appearance and his knowledge from the future. Naruto would have to prove himself to Kakashi. However, as they work towards a common goal, like saving Konoha from a threat in the past, they would gradually build trust. Their relationship could also change in terms of how they interact with others in the past. For example, they would need to pretend to be normal villagers or ninjas from that time, and this new situation would impact how they relate to each other.

Well, they could change a lot of things. Maybe Naruto would prevent some of the tragedies that happened in the past. He could stop the Nine - Tails attack on the village, which would completely change his own life and the lives of many in Konoha.

Their relationship would likely become more complex. At first, they might be more united because they have a common goal of changing the past. However, as they face different situations in the past, their differences could start to surface again. For example, Sasuke might be more focused on revenge - related issues from the past, while Naruto would be more interested in saving lives. This could lead to some arguments between them.

It might become stronger. They'd have to rely on each other more in the past, facing all the unknowns together.

Their relationship might become more complex. Since they'd be in a different time, they might rely on each other more. In their own time, they had different paths, but going back in time could force them to be closer. They might start to see each other in a new light, like Luke seeing Leia as more of a partner in adventure rather than just a sister.

Naruto's view of family would expand greatly. He has always been seeking acceptance and a sense of family. With Kurama as his sister, he now has a family member who is part of his very being. This could make him more empathetic towards others who are also searching for family. He would be more likely to reach out and help those in need, based on his own experience of finally having a true family connection in Kurama.

They would likely become more protective of each other. Kurama would be constantly on guard to keep Botan and the unborn child safe. Their relationship would deepen as they share the new experience of impending parenthood. For example, they might have more tender and private moments together, away from their usual adventures.

In this fanfiction scenario, their relationship could be more like brothers in arms. They both have regrets from their original timelines. They would rely on each other more deeply. Obito might open up to Naruto about his past and his love for Rin much earlier. Naruto could also share his own insecurities and how he overcame them in the future. This would create a stronger bond between them, and they would fight side by side more effectively against the common enemies, whether it's the Akatsuki or other threats to the ninja world.

Regarding his family, Hikaru could understand their support for his Go journey better. He might go back in time and be more open with them about his passion for Go. This could lead to his family being more involved in his Go - related activities, like attending more of his tournaments and providing more emotional support. Maybe his family could also play a role in promoting Go in the community because of Hikaru's influence.

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.
