Here are some recommended novels about school violence: Crossing the Wild and Daydreaming of Me. " Crossing the Wild " told the story of the female protagonist who was subjected to campus violence after transferring to another school. The male protagonist made a bet with her that they could talk for two months. In the end, the two of them liked each other and saved each other. " Daydreaming of Me " described the love story between the male school bully and the female protagonist. These novels showed the seriousness of school violence and the feelings of people relying on each other in difficult situations.
I don't think so. There haven't been any official announcements or indications that the HxH manga will continue. But you never know, maybe there'll be a surprise in the future.
