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.
Well, to answer that, we need to know more about the 'Impossible' you're referring to. Is it a film, a novel, or something else? If it's a work of fiction, chances are it's not a true story. But if it's a documentary or based on real people's experiences, then it could be.
It's not straightforward to determine. 'Impossible' could refer to events that are rare or unlikely in real life but not necessarily untrue. Or it could just be a fictional creation with no basis in reality at all.
Well, it might be a unique take within the series. Maybe it's about a mission that seems as impossible as dealing with a ghost, something very elusive and hard to grasp. It could introduce elements that are spooky or very difficult to overcome, like a mystery that's as hard to solve as proving the existence of a ghost.
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.
