In some fanfictions, the banished family might be wrongly accused. So in this case, they could be on a journey to clear their name. Along the way, they encounter Naruto and team up with him. They might face many challenges together, like fighting against other rogue ninja groups who want to take advantage of their situation. This would create a story full of action and adventure.
Some villagers might be in shock. Kushina was an important figure in the village's history, being Naruto's mother. There would be those who would question Naruto's decision and lose faith in him. They might start to fear for their own safety, thinking that if someone like Kushina could be banished, they could be next.
At first, Naruto might be shocked and heartbroken. He has always longed for family acceptance, so being banished by them would be a huge blow. He could feel betrayed and angry, especially if he doesn't understand the reasons behind it.
One possible reason could be fear. The villagers have always feared the Nine - Tails within Naruto. His family might banish him out of this same fear, not wanting to be associated with the potential danger he represents. Maybe they think that by banishing him, they can keep the village safe from the Nine - Tails' power getting out of control.
One possible reason could be a misunderstanding. Maybe some false information was spread about Kushina being a threat to the village, and Naruto, in his role as Hokage or a powerful figure, felt he had no choice but to banish her to protect the village. Another reason might be related to some sort of dark influence or curse that made Naruto act out of character and banish her.
Perhaps his family consists of a group of fellow banished ninjas who become his surrogate family. There could be a strong - willed female ninja who becomes his partner, and together they have a child. And also an old sage - like figure who acts as the family's wise elder, guiding them through the difficulties of living in exile.
One possible plot could be that Naruto, after being banished, discovers a new place where he starts his own family. He might meet a kind-hearted woman who accepts him for who he is. They could have a child together, and Naruto would be determined to protect his new family from any threats, including those who might still hold a grudge against him from his past in Konoha.
In the 'banished naruto has a family fanfiction', Naruto might be banished and end up on an island. There he meets a group of outcasts like himself. Among them, he finds a partner and they start a family. Their family grows up learning Naruto's ninja ways and they all strive to create a better life on the island, away from the politics and judgment of the ninja world that banished Naruto.
His wife could be an original character created specifically for the fanfiction. She could be a strong - willed healer who helps Naruto when he first arrives in the new place. Their child could inherit Naruto's blond hair and blue eyes, and have a unique combination of Naruto's ninjutsu skills and the mother's healing abilities.
