Well, without having read the 'lacrimosa of dana novel', it's hard to say precisely. However, based on the title, 'lacrimosa' is often associated with a sense of sorrow or weeping. So perhaps the story of Dana in the novel is filled with heart - breaking moments, like the loss of loved ones, or a struggle against an oppressive force. It might also be a coming - of - age story where Dana has to grow through these tough and sad experiences.
Since I don't know the details of this novel, I can't accurately name the main characters. But I assume Dana is likely to be one of the main characters as the title includes her name.
The world - building is a highlight. The game creates a vivid and detailed world that feels alive. Another highlight is the character development, especially the growth of the protagonist throughout the story.
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.
