Naruto Uzumaki was born in the Hidden Leaf Village. His parents died when he was young. He grew up lonely as he was shunned by the villagers because of the Nine - Tailed Fox sealed within him. But Naruto was determined. He trained hard at the Ninja Academy. He made friends like Sasuke and Sakura. Eventually, he became a strong ninja and fulfilled his dream of becoming Hokage.
Naruto's reaction could be complex. On one hand, he would be happy to find someone else from his clan. He has always been proud of his Uzumaki heritage despite not knowing much about it at first. But on the other hand, he might be a bit cautious. Karin has been associated with some not - so - good groups in the past. However, overall, his positive nature would probably lead him to approach Karin with an open mind and try to build a connection with her based on their shared Uzumaki roots.
Naruto would probably first try to find a peaceful solution. He has always been one to believe in the power of friendship and understanding. He might try to talk to the leaders of both villages, like Gaara in the Sand, to find out what's really going on and resolve the misunderstandings.
He is probably very excited. Naruto has always been eager to learn new things and become stronger. Finding an Uzumaki scroll means he has the chance to discover something unique about his own clan, so he would be filled with anticipation.
At first, Naruto might be shocked and confused. He would probably wonder why his own clan would do such a thing to him. He might feel a deep sense of betrayal, especially since he has always longed for a family and a sense of belonging within the Uzumaki clan. But being Naruto, he would soon turn his confusion and pain into determination. He would vow to prove himself and show the clan that they were wrong to exile him.
Naruto's life would be very different. He would be more respected in the ninja world for his unique skills. Instead of just being known for his Nine - Tails chakra, his sealing abilities would also be a major factor. He could use his sealing skills to protect the village in new ways, like creating powerful seals around Konoha to prevent enemy attacks. Also, he might be called upon more often to deal with dangerous artifacts or threats that require sealing.
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.
The key events include the Nine - Tailed Fox attack when he was born, his lonely childhood in the village, his time at the Ninja Academy, making friends like Sasuke and Sakura, training with Jiraiya, and finally becoming Hokage.
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.
