No. In the original Naruto series, Naruto has a strong and faithful relationship with Hinata. Fanfics like this often go against the core values and established relationships in the official story, and are just the wild and unfounded creations of some fans.
Well, one reason could be that some fans are just exploring alternative storylines out of boredom. They might think it's interesting to see what would happen if they break the established relationships in the Naruto world. Another reason could be that they are trying to add more drama to the story. However, these fanfics don't represent the true nature of the Naruto characters as they are in the official series.
For Hinata, her development could focus on her becoming more assertive. In the fanfic, she could start taking on leadership roles within the clan. With her relationship with Naruto, she could also gain more confidence. For Hanabi, her development could be about her learning to be more empathetic. She might start to understand the feelings of others more, especially her sister Hinata. This could be shown through their interactions, like when they have heart - to - heart conversations.
I'm not sure if there is a specifically family - friendly fanfic with such a plot. Fanfics often explore various scenarios, but this one involves a rather controversial and unfaithful concept which may not be in line with the positive values usually associated with family - friendly content. However, there could be some authors who try to handle it in a more moral or educational way, but it's not common.
I'm not sure if there is a specific 'hinata cheats on naruto fanfic' that meets those criteria. Fanfics can vary greatly in quality and content. Some might use this concept in a shock - value way, while others could try to build a more in - depth story around it. But it's also important to note that this is a rather controversial idea considering Hinata's loyalty in the main story.
There might be some fanfics out there with such a plot, but it's not a positive or common representation of the Naruto characters. In the Naruto series, Hinata has always admired Naruto from afar and they end up together. Sasuke has his own story arc that is mainly focused on his revenge and redemption. Changing their relationships in such a way in a fanfic seems like a distortion of the original story's essence.
I'm not sure if there is such a fanfic. Cheating storylines in fanfics can be quite controversial as they go against the positive relationship often depicted between Naruto and Hinata in the original work.
A plotline might revolve around Hinata and Hanabi training together. They could discover a new jutsu that was lost in their clan's history. Hinata, with her gentle yet powerful nature, and Hanabi, being more headstrong, could face challenges during the training process. This could lead to them growing not only as ninjas but also as sisters, strengthening their bond and also their place within the Hyuga clan. And along the way, they might encounter Naruto, who offers some unique perspectives on their training and clan traditions.
Naruto would be extremely hurt. He loves Hinata deeply and to find out she cheated with Kiba would be a huge blow to him. He might go into a state of shock and disbelief at first.
The main characters would obviously be Naruto and Hinata as the parents of the super babies. The super babies themselves would also be main characters. And Hanabi, as Hinata's sister, would be an important character too. She might have a role in the upbringing or training of the babies.
