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.
I don't have enough information to fully define who Kara Robinson is just from this 'watch the Kara Robinson story' statement. She could be an ordinary person who has had an extraordinary experience, or perhaps someone who has made an impact in a particular field or community.
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.
In the context of a fanfic, Harry and Kara are likely fictional characters created by the fanfic author. They could be based on real - life individuals the author admires, or they could be completely original characters within a particular fan - created universe. Harry might be a charming, kind - hearted guy, and Kara could be a strong - willed woman. Their personalities would be developed by the author to drive the plot forward, especially in relation to the pregnancy storyline.
In the fanfiction, Kara Lemon could be an original character created by the author. She might be a muggle - born witch who discovers her powers later in life and is then thrust into the magical world of Harry Potter.
As of now, no. In the Boruto series, their relationship is mainly focused on their friendship and comradeship as ninja. There are some moments that fans might interpret as having a hint of something more, but the story has not made their relationship a romantic one in an official capacity.
No. The official Boruto series is focused on the growth of Boruto, his friends, and the new generation in the ninja world. Fanfics are often creative interpretations by fans, but this one sounds like it's not in the spirit of the official series at all. It's likely a non - official and inappropriate creation that has no place in the official Boruto story.
