Most likely, one of the main characters is the maid herself. She is probably the center of the story in many ways, bringing her own personality and backstory into the plot.
In some cases, there could be a villain - like character. Maybe it's someone who tries to create problems between the maid and the person she lives with. This could be an ex - girlfriend of the protagonist who is jealous of the maid's presence or a nosy neighbor who spreads false rumors about their relationship, adding some drama and conflict to the story.
I'm not sure as there's no specific information given, but they could be ordinary people on a journey to find happiness.
As I don't know the exact 'the maid novel', it's hard to say. But generally, the maid herself would be a main character. There might also be an employer, like a wealthy lady or a family patriarch.
Based on the title, the main characters are likely Miss Lisette and the assassin maid.
The main characters are presumably the man and the maid. However, we can't rule out other important characters. For example, if it's a historical novel, there could be a lord as the man and a young peasant girl as the maid. There might be a butler who is also an important part of the household and has an influence on the relationship between the man and the maid. Or there could be a love interest for the man other than the maid, which would add more complexity to the story.
Obviously, the maid and the vampire are the main characters. The maid might be an ordinary girl who gets caught up in the extraordinary world of the vampire. The vampire could be a centuries - old creature with a complex personality. There may also be a character like the maid's friend or family member who plays a role in the story, perhaps by trying to protect her from the vampire or getting involved in the vampire - related affairs.
Since we have no details about this novel, it's impossible to say for sure who the main characters are. However, they might include a hero or heroine who discovers the living force and has to deal with its consequences. There could also be villains who want to misuse the living force for their own evil purposes. And perhaps there are side characters who help or hinder the main character's journey regarding the living force.
I don't have enough information to determine the main characters in this 'land of the living novel'.
There's no way to know precisely without reading it, but it might have a main character who is on a journey to discover the truth about the dead. Maybe there's a group of people who live near a place that is said to be haunted, and they are the main characters. They could be trying to figure out if there's a real connection between the living and the dead in that area.
Well, it might have storylines about the daily interactions between the main character and the maid. Maybe there are heart - warming moments like sharing meals or having conversations about their dreams.
I don't know for sure if there are interesting characters in it as I haven't experienced this visual novel directly. But typically in a maid - themed visual novel, there could be a headstrong maid character who is always trying to do her best, or a shy maid who gradually comes out of her shell. There might also be a strict but fair mistress or master character that the maids interact with.
