Naruto's reaction could be complex. He would feel a deep sense of loss and loneliness. But he has the spirit of never giving up. He might start to question the concept of family and what it really means. This self - reflection could lead him to grow as a person. He could also become more empathetic towards others who have been rejected or abandoned. In his journey, he might encounter people who have similar experiences, and together they would form a bond and support each other while he tries to find his place in the world without his family.
Naruto might initially be heartbroken. He has always longed for his father's love and acceptance, so being disowned would be a huge blow. He could go into a state of depression for a while, withdrawing from his friends and normal activities. But then, Naruto is a fighter. He would likely start to question his father's decision and try to find out the real reason behind it, vowing to prove himself worthy if there was some misunderstanding.
One possible reason could be his status as a Jinchuriki. In the Naruto universe, being a Jinchuriki is often seen as a curse and a threat. His family might be afraid of the danger it brings to them and the village, so they disown him. Another reason could be political. Maybe there are some power - hungry individuals in the family who see Naruto as a liability to their power - grabbing plans.
Naruto would likely become more independent. Without the support of his family, he'd have to rely on himself more. He might develop a tougher exterior and be more cautious about who he trusts.
Another storyline could involve Naruto uncovering a dark secret within his family that led to his disownment. As he digs deeper, he realizes that there were misunderstandings and forces at play that he needs to confront. This could lead to a complex and emotional journey of reconciliation or acceptance of his new situation.
In such a fanfiction, the plot might involve Naruto feeling extremely alone and betrayed. He could start to question his self - worth. Maybe he'll set out on a journey to prove himself not only to the clan but to the whole village. He might find new allies outside the clan who see his potential and help him grow stronger.
Naruto could start to focus more on building relationships outside of his clan. He would seek acceptance from his friends like Sasuke, Sakura and Kakashi. Their support would give him the strength to rise above the situation. He might also start to explore different jutsu and skills on his own, without relying on any clan teachings.
Naruto's character would likely become more hardened. He would have to grow up fast and learn to rely on himself. His usual cheerful and outgoing nature might be replaced with a more reserved and determined one. He'll still have his goal of becoming Hokage, but it would now be also about proving his clan wrong.
Naruto's character could develop a sense of isolation at first. But as he overcomes challenges, he would start to form new bonds with people who believe in him. These new relationships could help him grow in ways he hadn't before. For example, he might learn different fighting styles from new allies. And ultimately, his experience of being disowned could make him a more well - rounded and mature ninja, better equipped to handle future crises in the ninja world.
It could be related to some prophecy or superstition within the clan. They might think Naruto is a bad omen or something that goes against their traditional beliefs, so they decide to disown him.
In this type of fanfiction, it could be that Kushina has a misunderstanding about Naruto's goals. For example, if Naruto starts to befriend some people from other villages that are seen as potential enemies by Konoha. Kushina, being a very loyal Konoha - nin, disowns him. Naruto would have to prove that his actions are for the greater good of all villages and not just Konoha.
