It could be that Hiashi is a very traditional person. In his view, Hinata should focus on the real Naruto story, not fan - made fictions. He might worry that fanfiction could deviate from the values and storylines that he believes are important for Hinata to uphold. For example, fanfiction might change the relationships between characters in a way that he doesn't approve of, and he doesn't want Hinata to be exposed to such ideas.
Well, Hiashi might be concerned about the quality of fanfiction. There is a lot of fanfiction out there that is poorly written. He may not want Hinata to waste her time on such low - quality content. Also, some fanfiction could have a negative impact on Hinata's perception of the Naruto universe. He wants her to have a pure and positive understanding of the original story, so he forbids her from engaging with fanfiction.
Maybe Hiashi thinks Naruto fanfiction might contain inappropriate or untrue portrayals of the Naruto world and characters. He wants to protect Hinata from being influenced by such potentially inaccurate or improper content.
One possible reason could be that Hiashi might see Naruto as a threat to the Hyuga clan's secrets or traditions. Naruto is often associated with unpredictable and powerful abilities, and Hiashi, being protective of his clan, may want to keep him at a distance to safeguard the clan's interests.
In some fanfictions, Naruto might use his newfound jutsu skills. He could quickly dash in between Hiashi and Hinata, using his speed and agility to block any attacks Hiashi might be launching towards Hinata. His Rasengan in his hand, ready to defend if Hiashi doesn't back down. This shows Naruto's determination to protect Hinata from any harm, even from her own father in this fictional scenario.
One possible reason could be that Naruto is in love with a Hyuga clan member. Since Hiashi is the head of the Hyuga clan, Naruto might think it's proper to ask for his blessing. For example, if he has feelings for Hinata, Hiashi's daughter. Hiashi's approval would mean a lot in terms of family and clan acceptance.
Well, their friendship is like a foundation. Naruto, having known Hinata for a long time, values her. In the situation where he has to save her from Hiashi, his friendship is what pushes him to put himself in harm's way. He remembers all the times they've shared, the support Hinata has given him in the past. This makes him determined to return the favor and protect her. It also means he's more likely to understand Hinata's perspective and try to resolve the issue between her and Hiashi in a way that benefits her in the long run.
One possible motive could be a misunderstanding. Maybe Hiashi mistakes Naruto for an enemy who has infiltrated the village in disguise. Another reason could be related to clan politics. If Naruto somehow gets involved in a situation that threatens Hiashi's clan interests, Hiashi might take extreme measures.
Maybe the fanfiction portrays Hinata in a way that doesn't align with her true character. For example, it might make her overly aggressive or weak in a way that doesn't fit the original concept.
One possible reason could be misrepresentation of her character. In some fanfictions, authors might change her personality to fit a certain plot, like making her overly jealous or mean, which would be out of character for the gentle Hinata. This could make her seem unlikable and thus anger fans who love the original Hinata.
It could be due to external pressures. Maybe the village has certain expectations of them as a couple that they can't meet. Or there could be a threat to the family that Naruto, in his role as a protector, doesn't handle well, making Hinata lose faith in their relationship.
Maybe she wants to keep her real relationship with Naruto pure. Fanfiction can be full of all sorts of wild and untrue interpretations of their relationship. She values what she has with Naruto in reality and doesn't want to be influenced by fictional ideas. For example, some fanfictions might create unnecessary drama or unrealistic scenarios between them.
One possible reason could be a huge misunderstanding. Maybe he thought Hinata did something really bad to his friends, like unknowingly leading the enemy to them. Without knowing the truth, his hot - headed nature made him lash out.
