Naruto might feel a sense of responsibility. He would see it as his duty to help Boruto understand and control the Jougan. So, he could start to create special training regimens for Boruto. These regimens would be designed not only to strengthen Boruto's physical and ninja skills but also to help him master the unique powers that come with the Jougan. He would also teach Boruto about the importance of using such power for good and protecting the Hidden Leaf.
In fanfiction, if Naruto discovers Boruto's Jougan, it could change the power dynamics in the Hidden Leaf. Naruto would likely be both proud and worried. Proud because his son has such a unique and potentially powerful ability, but worried because it might attract unwanted attention. He could start to share his own experiences with dealing with unique powers more openly with Boruto. This might include stories about how he tamed the Nine - Tails' power. He would also probably consult Kakashi, his former teacher, to get some insights on how to guide Boruto in harnessing the Jougan's power safely and effectively.
It could also mean that a major chapter in Boruto's life has ended. Maybe a big battle or a long - running conflict has been resolved, and this is the end of that particular part of the story. However, it doesn't mean the whole series is over. There could be spin - offs or new storylines that start from this 'end'. For instance, a new generation of ninjas could be introduced who are inspired by Boruto's story so far.
Well, it's not necessarily the absolute end. It could be a cliffhanger or a way to create suspense. Sometimes in anime, they say things like this to make the audience think about what might come next. Boruto might face new challenges that are even greater, and this statement is just a pause in the story. For example, there could be a new villain emerging from the shadows, and this 'end' is just the calm before the storm.
In many fanfictions, Naruto's reaction is a mix of shock and determination. The shock comes from finally learning about his clan, and the determination is to uphold the Uzumaki name. He could start wearing something that represents the Uzumaki clan, like a symbol on his clothing. He also may become more protective of the Uzumaki secrets and legacies he discovers.
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.
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.
Naruto would be devastated. He might blame himself for not being able to protect his son. Sasuke would be angry and would likely go on a hunt for the perpetrator. His friends like Sarada and Mitsuki would be heartbroken. Sarada might vow to become stronger to prevent such a tragedy from happening again.
