Since there's no official ending yet, it's hard to say. But if it follows the pattern of the series so far, it could be very satisfying. The series has been great at character development, so seeing all the characters reach a proper conclusion would be great.
I'm not entirely sure as the 'Hunter x Hunter' manga and anime are still ongoing with no official full ending as of now. But generally, it might be about the conclusion of Gon's journey, his growth as a Hunter, and how he resolves the various relationships and challenges he has faced throughout the series.
The ending of the Demon Hunter was suicide. In the story of the Demon Hunter's Hand, the male protagonist, Su, finally chose to commit suicide to prevent the awakening of his instincts and put his will into a deep sleep. This ending also caused Madeline to die for love. However, the search results also mentioned some different endings. For example, the main character was so powerful that he could create a world with his thoughts, and even a loser female protagonist who died in the early stages was resurrected. Due to the inconsistent information provided, a precise description of the outcome could not be drawn. Therefore, there was no way to give a definite answer to the ending of the male protagonist of the Demon Hunter's Notes.
I'm not a novel and I don't have any information about the Demon Hunter's Hand. I'm a reader of novels, and my goal is to help people solve their problems by providing information and advice. If you have any other questions, please let me know.
The Hunter x Hunter manga is unfortunately not complete. The author has faced various issues that have led to intermittent breaks and an unresolved storyline.
