One interesting plotline could be Naruto discovering his Uzumaki heritage in a more in - depth way within the harem context. Maybe he finds ancient Uzumaki scrolls that not only enhance his powers but also make him more attractive to the female characters in the harem. Another could be Naruto having to protect his harem members from enemies who target him because of his Uzumaki clan connection. This could lead to some intense battle scenes and character development for both Naruto and his harem.
Karui could be one of the characters. Since she is from the Hidden Cloud Village and has a connection to the Uzumaki clan through her son's relation to Naruto. Another could be Hinata. Although she is from the Hyuga clan, her love for Naruto and the Uzumaki influence on Naruto's life could bring her into the story. Also, Tsunade, as she has a connection to the Senju clan which is related to the Uzumaki clan.
Well, he could start a family with Hinata and have lots of kids, passing on his Uzumaki bloodline. Then, he could encourage his friends who have some Uzumaki connection, like Karin, to also have families and pass on their Uzumaki genes. He could also set up a school or training center in the Uzumaki land, teaching the Uzumaki ways of life and ninjutsu, which would attract orphans or those who want to be part of the Uzumaki clan.
Perhaps a plot where Naruto, being of Uzumaki descent himself, has to help the female members of the Uzumaki harem unlock their latent powers. This could involve training sessions that also double as opportunities for romantic development. Or, a plot where the Uzumaki harem has to work together with Naruto to uncover a long - lost Uzumaki clan secret that could change the fate of the ninja world.
Well, it could be that the Uzumaki clan has some hidden knowledge or ancient artifacts. In the fanfiction world, they might discover an artifact that has the power to save Naruto from a life - threatening situation. Maybe it's a charm that can heal his wounds or reverse a curse placed on him. And since the Uzumaki clan has a rich history, there are many ways they could use their heritage to save Naruto.
Yes, there are likely fanfictions with this premise. Naruto being an Uzumaki has a strong connection to the clan. In many fanfictions, authors explore the idea of Naruto taking on the role of the clan head. This can lead to various storylines, such as him restoring the Uzumaki clan to its former glory, uniting remaining members, and using his position to bring about positive change in the ninja world. It also allows for exploration of Uzumaki clan lore and powers that Naruto could inherit and develop further.
Naruto could also offer incentives for Uzumaki to have children. For example, providing better living conditions, education, and protection. He might also use his influence to find suitable partners for the remaining Uzumaki members, both within the village and from other allied villages. This way, they can start new Uzumaki families and gradually increase the clan's numbers.
Naruto could learn about the Uzumaki clan's sealing techniques. They were masters of sealing jutsu. In the fanfiction, he might find out how they developed these complex and powerful sealing techniques, which were passed down through generations. It could be that he discovers some unique seals that were only known to the Uzumaki clan and how they were used for various purposes, like containing powerful entities or storing chakra.
Hinata is often included. Her long - standing crush on Naruto makes her a natural fit in the harem. Sakura could also be part of it. Even though she had feelings for Sasuke initially, in the harem fanfiction context, her relationship with Naruto could develop in a different way. And then there's Ino, who is strong - willed and could add an interesting dynamic to Naruto's harem due to her competitive nature.
