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.
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.
Manga is definitely a form of comic. It often features sequential panels and visual storytelling, similar to other comics. However, it may have its own cultural and artistic nuances that set it apart from some common book formats.
In my opinion, the Boruto manga has its merits. The character development and plot progression are interesting, and it expands on the Naruto universe in a fresh way. However, it might not be everyone's cup of tea.
