One possible plotline could be Naruto as the 6th Hokage facing a new threat to the village. Hinata, being his wife, supports him from behind the scenes. She might use her Byakugan to gather intelligence. Naruto, with his leadership skills and Hinata's support, unites the village to combat the enemy.
In this fanfiction, there could be a story where Naruto discovers a long - lost power and Hinata is the key to unlocking it. As the 6th Hokage, Naruto has to keep the village safe while also exploring this new power with Hinata by his side. Their love for each other could be what gives them the strength to face any challenges that come their way.
One possible fanfiction could be about Naruto, as the 6th Hokage, facing a new threat to the village while Hinata supports him. Maybe they have a family already, and Naruto is trying to balance his duties as Hokage and a father. Hinata, with her gentle yet strong nature, could be the one who keeps the family together during the tough times.
They could go on adventures together. As the 6th Hokage, Naruto would have access to all kinds of resources and knowledge. Hinata, being his wife, could accompany him on some secret or important missions. For example, they might go to explore an ancient ninja ruin to find a powerful artifact that could help protect the village. Along the way, they would face various traps and enemies, and their love for each other would be tested.
A plotline could be Tsunade trying to reform the medical ninja system in the village. There could be corruption or inefficiencies that she wants to address. This would involve her facing opposition from some of the established medical ninja families. She would have to use her authority as the Hokage to push through changes that would ultimately benefit the village in times of war and peace.
One possible plotline could be Naruto using his newfound time - traveling ability to prevent some of the major tragedies in the past. For example, he might try to stop the Uchiha massacre. He could also use his knowledge from the future to help his younger self become stronger faster, perhaps by teaching him some advanced jutsu he learned later in life.
One possible plot could be Naruto dealing with the post - war reconstruction. He might focus on rebuilding the village, strengthening relations with other villages, and also mentoring the new generation of ninjas. For example, he could start new training programs inspired by his own experiences.
A plotline could be Naruto having to deal with the remnants of old enemies. Some of Orochimaru's followers might still be causing trouble, and as Hokage, Naruto has to stop them without using excessive force. He wants to show mercy but also protect the village. Another aspect could be Naruto working on the village's infrastructure. He realizes that a strong village isn't just about having powerful shinobi but also about having a stable and prosperous community. So he starts projects like building new schools for ninja training and improving housing for the villagers.
Naruto himself could be a likely candidate. Given his strength, leadership skills, and his dream of uniting the ninja world, he would make a great 6th Hokage.
Sasuke could also be a possibility for the 6th Hokage in the fanfic. He has grown stronger over the years and his unique perspective on the ninja world could bring new ideas to the leadership of the Hidden Leaf. He might start off as a controversial choice but prove himself through his actions in protecting the village and making tough decisions.
Well, if Naruto becomes the 5th Hokage in fanfiction, he would surely bring a new energy to the village. He might start by reforming the ninja training system. Since he had a tough time growing up as an outcast, he'd make sure no kid in the village ever feels that way. He could also focus on better relations with other villages. Naruto's always been about peace and friendship, so he'd probably organize more joint ninja missions with other villages to build trust.
In fanfictions, Hokage Naruto and Hinata could go on various adventures. They might explore unknown parts of the ninja world together. This could be to find new techniques or to establish diplomatic relations with far - flung villages.
