In some fanfictions, Naruto might return to Konoha to a cold reception because the villagers still hold grudges from his past. Maybe they haven't fully accepted his power or the chaos he sometimes brought. For example, they could be afraid of his Nine - Tails power flaring up again and causing destruction.
He would most likely meet his father, Minato Namikaze, and his mother, Kushina Uzumaki. These are the two main family members he never really got to know growing up.
Perhaps it could be someone from his own village that he never really noticed before. Like a girl who was always in the background but during his time away, she grew into a confident and beautiful woman. She could be someone who works in the hospital, and Naruto starts to see her in a new light when he comes back injured from a mission.
In the 'naruto family returns fanfiction', it could be that Naruto's family returns to the village during a time of celebration, like a big festival. But they soon find out that there are some underlying issues in the village, such as political unrest or a new group of villains secretly operating. Naruto then decides to use his influence and his family's combined strength to solve these problems and bring peace back to the Hidden Leaf. He might also use this opportunity to teach his children about the importance of protecting their home and the values of the ninja way.
Another idea is that the girlfriend is actually someone with a mysterious past related to Naruto's own past, like she might be related to an old enemy or have some connection to the Nine - Tailed Fox. This would add a whole new layer of mystery and intrigue to the story. Naruto would have to deal with not only his feelings for her but also the secrets she might be hiding and how they could affect the safety of Konoha.
Obviously, Naruto and Sakura are the main characters. Naruto is the one who has been away and is now coming back. Sakura, being his friend and potentially more in the context of this fanfiction, is waiting for him in the village. Their relationship is a central focus, and other characters from the Naruto universe might also play supporting roles depending on the specific story.
One possibility is that Naruto has been on a long and secret mission. During this mission, he somehow ends up taking care of a baby. Maybe the baby is an orphan from a village he saved. Naruto, with his big heart, couldn't leave the baby behind. So he returns to the Hidden Leaf Village with the baby, causing a stir among his friends and the villagers. Some might be worried about how he can handle being a ninja and taking care of a baby at the same time, while others are just happy to see him back.
Obviously, Naruto and Temari are the main characters. Naruto, the hero of the Hidden Leaf Village, known for his determination and powerful ninja skills. And Temari, a strong - willed kunoichi from the Hidden Sand Village, with her own set of impressive abilities.
The plot could involve Naruto coming back to find that the political situation has changed. Temari, being from Suna, could be there to help Naruto navigate the new power dynamics. They might have to deal with other villages that are becoming more aggressive. Naruto's return with Temari could also signal a new era of cooperation between the Leaf and Suna, and they could be at the forefront of diplomatic efforts. Plus, there could be some personal moments between them, like Naruto finally realizing his feelings for Temari during their adventures together.
Perhaps the relationships in the story are changed. His friendships with Sasuke, Sakura, and others might be altered. He could return and find that his friends have grown in unexpected ways, leading to new dynamics between them.
