The Legend of Uzumaki Hiroto was a derivative work of Naruto, which told the story of Uzumaki Hiroto's growth and the stories of other characters. Uzumaki Boto Legend was different from the original Naruto Naruto Shimbun Legend, so it was considered an independent manga.
It depends on the specific plot of the fanfic. Sometimes he could be on a secret mission, in a hidden village, or facing a new challenge in an unknown location.
One of the main themes is love. Not just the mother - son love between Naruto and Kushina, but also how Kushina's love for Naruto can be a driving force in the story. For instance, in some fanfics, Kushina's love gives Naruto the strength to overcome great challenges. Also, the theme of sacrifice is common. Kushina sacrificed herself for Naruto, and fanfics often expand on this idea, showing how Naruto honors her sacrifice and what it means for his character development. In addition, there's often a theme of discovery, where Naruto discovers more about his mother and his own identity as an Uzumaki.
One interesting fanfiction could be about Mit Uzumaki and Naruto Uzumaki teaming up to face a new, powerful enemy that the Hidden Leaf Village has never seen before. They could combine their unique skills and family powers to protect the village.
In many fanfictions, Naruto might obtain the Uzumaki sword through a hidden inheritance. Maybe it was left behind by an ancient Uzumaki clan member and Naruto discovers it in a secret location, like an old, forgotten Uzumaki shrine.
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.
Kushina Uzumaki was known for her fiery red hair and strong will. She was a Jinchuriki, just like Naruto, which made her both powerful and a target. Her love for her family, especially Naruto, was unwavering. Even though she sacrificed herself early in Naruto's life, her influence on him was profound.
One aspect to consider in Naruto and Kushina Uzumaki fanfiction is their relationship. Kushina was Naruto's mother. Fanfictions often explore how their bond could have been different if she had survived. For example, she could have taught Naruto more about the Uzumaki clan's secrets. This would have given Naruto an even greater power boost and a deeper understanding of his heritage.
Kushina Uzumaki is significant in Naruto fanfiction as she represents a link to Naruto's past. Her red hair and strong Uzumaki blood are often explored in fan stories. Writers may use her to introduce new plot elements related to the Uzumaki clan.
