When Naruto discovers Jiraiya's death in fanfiction, it's a moment of pure shock. He may immediately recall all the lessons Jiraiya taught him, from the Rasengan to the importance of never giving up. This news could fuel his determination to become stronger, not just for himself but also to avenge Jiraiya. He might also have flashbacks of their adventures together, which only intensifies his pain.
In some fanfictions, Naruto is completely devastated. He might go into a state of shock at first, unable to believe the news. Then he could be filled with intense grief and anger, blaming himself for not being there to protect Jiraiya.
Sasuke might be initially shocked. He has always seen Naruto as a rival and suddenly finding out Naruto is a girl could completely change his perception. He may start to view Naruto in a more protective way, as his traditional views of gender roles might make him feel the need to safeguard her now that he knows she's female.
In many fanfictions, Naruto is initially in a state of shock. He can't believe that Jiraiya, his mentor, is gone. He might go into a period of deep sadness and isolation, withdrawing from others as he tries to process the loss.
Well, if Sasuke finds out Naruto is a girl in fanfiction, it could completely change their dynamic. Maybe Sasuke would start to see Naruto in a new light, perhaps more protectively. Their relationship might become more romantic as Sasuke realizes his feelings for Naruto are different from what he thought. It could also lead to some interesting plot twists, like Sasuke having to re - evaluate his rivalry with Naruto.
Sasuke would likely first show a stoic exterior when he finds out. However, internally, he's in turmoil. On one hand, he's happy that he and Sakura are going to have a child. On the other hand, he's worried about the potential dangers his family could face because of his past enemies. So, he might start making plans to keep them safe, like finding a more secure place to live.
Some characters might be really surprised. Sakura, for instance, might be jealous as she has feelings for Sasuke and now Sasuke might show more interest in Naruto as a girl. Kakashi might be more protective of Naruto, knowing that this new revelation could bring some challenges. And the other ninja in the village could start to treat Naruto differently, either with more respect or in some cases, with unwanted attention.
Naruto may also have to re - evaluate her own identity. She has been living as a boy for so long, and now that Sasuke knows the truth, she may start to question how she wants to present herself in the future. Does she continue to be a ninja in the same way, or does she embrace her femininity more? This could be a major internal struggle for her.
One possible development is that Sasuke becomes more involved in the village. He realizes he needs to create a stable environment for his family, so he starts to take on more responsibilities in the village.
In some fanfics, Sasuke might initially be shocked. He could then feel a mix of joy and fear. Joy because he's starting a family with Sakura, but fear because of the responsibilities and potential dangers that might come with it.
