Naruto is the obvious one. His connection to the Uzumaki clan makes him the driving force behind the rebuilding. Hinata would also be likely involved, as Naruto's wife, she would support him and might contribute to the new Uzushiogakure in areas like family support and community building.
Obviously, Naruto would be one of the main characters. He's the driving force behind the rebuilding of Uzushiogakure. Hinata might also be involved, as she is Naruto's wife and could offer her support, perhaps in terms of taking care of the villagers' needs. Another character could be Kakashi. His experience and wisdom would be valuable in guiding Naruto through the process, especially when it comes to handling political aspects or dealing with potential threats.
Sasuke is likely to be involved. He and Naruto have a complex relationship and Sasuke has become an ally. He could offer his strength in combat to protect the rebuilding efforts. Also, Sakura. She's a skilled ninja with medical abilities that could be useful if there are any injuries during the process.
It could center around Naruto facing challenges during the rebuilding process. There could be political opposition from other villages who fear a strong Uzushiogakure again. Naruto would then have to prove that the rebuilt village is a force for good in the ninja world, perhaps by forging new alliances and treaties.
There could be some of the older Uzushiogakure ninjas who survived the previous disasters. They would play an important role in guiding Naruto about the secrets of the village. And maybe some new characters could be introduced, like a young Uzushiogakure ninja who looks up to Naruto and helps him in his quest to save the village.
In this fanfiction, a major plot point is likely Naruto facing opposition. Some might not believe Uzushiogakure should be rebuilt, either due to past grudges or political reasons. Also, Naruto would need to find a way to preserve the history and culture of Uzushiogakure during the rebuilding process. This could involve searching for ancient texts or artifacts related to the village. He may also encounter challenges in training new shinobi in the ways of Uzushiogakure, as the techniques might have been lost over time.
There could also be some new characters created specifically for the fanfic. Maybe a foreign diplomat who comes to Konoha and Naruto is the first one to welcome him and befriend him. This would open up new storylines about international relations in the Naruto world and how Naruto's friendship can have a positive impact on a larger scale.
Obviously Naruto himself is the central character. Sasuke would also likely be involved. Given their history and Sasuke's own complex relationship with Konoha, he might side with Naruto or at least be a key figure in the events. Kakashi too, as he has been Naruto's teacher and is an important figure in Konoha. He could be caught in the middle, trying to understand Naruto's motives and also trying to uphold Konoha's stability.
Definitely Hinata. Her gentle yet strong - willed nature could be an interesting contrast when dealing with the often - mischievous yokai from Nurarihyon. Gaara too, as his own experiences with being an outcast and having a powerful force within him could have parallels in the Nurarihyon world where some yokai are feared or misunderstood. And Rock Lee, his determination and unique fighting style could bring a new dynamic to the interactions in the fanfic.
Obviously, Naruto is the central character. But other characters like Sasuke could also be involved. Sasuke might be torn between his loyalty to Konoha and his friendship with Naruto. He could either try to bring Naruto back or join him in his exile.
Sasuke is a very likely character. He already has a strong connection to hate in the original series due to his clan's massacre. In a fanfic about the power of hate, his journey could be further explored, like how he might be tempted by even darker forms of hate - driven power. Another one is Obito. His fall into darkness was also driven by hate, and in a fanfic, his character could be used to show the extreme lengths that the power of hate can take someone.
