At first, Naruto would be deeply hurt by the banishment. But as he becomes a father to his daughter, his focus shifts. He starts to see the world from a different perspective. He becomes more nurturing and patient. His experiences of being an outcast would make him teach his daughter to be strong both physically and mentally. He might also develop a sense of wisdom as he tries to guide her through life, away from the politics and drama that got him banished in the first place.
One idea could be that the daughter has to hide her identity in the village that banished Naruto. She might inherit some of Naruto's unique abilities like his shadow clones. She could use these abilities in secret to help the villagers without them knowing she's related to the banished Naruto.
Well, in this fanfiction scenario, perhaps Naruto's daughter is born with some unique power that was passed down from Naruto's Uzumaki heritage. Naruto, being banished, is determined to keep her safe from the forces that might want to use or harm her. The story could follow their journey as they encounter various challenges and make new allies along the way. They might even form a small community of outcasts who support each other.
The daughter could also inspire a new generation. Young ninjas in the village might look up to her, especially if she has unique skills. This could lead to a change in the way ninjas are trained or how they view loyalty and family in the context of being a ninja.
His daughter's character might develop with a lot of compassion. Growing up with a banished father, she would understand what it's like to be an outcast. This could lead her to be very empathetic towards others who are also mistreated or misunderstood. She could also inherit Naruto's never - give - up attitude and use it to face any difficulties in her life. For example, if she faces discrimination because of her father, she would keep fighting to prove herself. And as she gets older, she might start to explore her own identity, not just as Naruto's daughter, but as an individual with her own dreams and goals.
Hinata could also be a common character. She may try to help Naruto secretly, or be heartbroken by his banishment and strive to change the village's decision. Another character could be Kakashi. He might be one of the few who believe in Naruto's innocence and try to find a way to bring him back to the village.
He could marry Hinata. Even though he's banished, Hinata might follow him because of her deep love for him. Their relationship could develop further outside the village, and they could get married and start a family.
One possible plot could be Naruto going on a journey to prove his worth after being banished. He might encounter new allies and enemies, and develop new jutsu.
Definitely Naruto is the central figure. In the harem, Hinata is a very likely character since she has always been in love with Naruto. Sakura might also be there as she has been one of Naruto's closest friends. Tenten could be another addition. She has interacted with Naruto in the series and could potentially be part of the harem in this fanfiction. Also, Temari, who has had some interesting encounters with Naruto, might be a character in the harem as well.
Well, if Naruto is banished and gets married in a fanfiction, it could go in many directions. Maybe he marries a foreign ninja. His banishment could be the start of a journey where he discovers new jutsu and cultures. His marriage could be a political alliance as well. His new wife could be from a powerful clan in another country, and together they could work towards peace between their lands while also building a loving family.
