Well, Boruto might have a range of reactions. If the fanfiction shows Naruto as a really powerful and cool hero, which he is, Boruto would probably feel proud. But if it's something that twists Naruto's character in a negative way, he would likely be angry or defensive. He respects his father a great deal, so any false portrayal could upset him. He may also find some of the more out - there or creative fanfictions amusing, like ones that put Naruto in a completely fictional adventure that's way different from what actually happened.
In a fanfiction where Boruto fights Naruto, it could be a very emotional battle. Boruto might be driven by his desire to prove himself as a ninja independent of his father's shadow. He could use his unique jutsu, like the Vanishing Rasengan. Naruto, on the other hand, would bring his vast experience and the power of the Nine - Tails. It could end in a draw with both realizing the importance of family and understanding each other better.
Boruto would probably be really flustered. He might start stuttering and making excuses, like blaming it on the situation. Sarada, on the other hand, would likely be very shy and might avoid looking at Boruto directly for a while.
No, Boruto is alive in the manga. The plot hasn't led to his death. However, the manga is ongoing, and anything could happen in the later developments.
Yes, Boruto is indeed a manga. It expands on the Naruto universe and offers fresh perspectives and storylines. Many fans enjoy reading it to delve deeper into the world created by the series.
Naruto would be devastated. He might blame himself for not being able to protect his son. Sasuke would be angry and would likely go on a hunt for the perpetrator. His friends like Sarada and Mitsuki would be heartbroken. Sarada might vow to become stronger to prevent such a tragedy from happening again.
