It's possible that the main characters are a group of people with different backgrounds. Maybe there's a scientist who is trying to find a way to stop the spread of the 'lesser dead', a journalist who is documenting the events, and a young person who has some sort of special ability to sense the presence of these undead. Their interactions and personal growth throughout the novels would be interesting to follow as they face the horror of the 'lesser dead'.
One notable feature could be their unique take on horror. Maybe they explore less common horror themes, setting them apart from mainstream horror novels.
I'm not sure specifically without reading the novel, but they could be characters who represent the 'children of a lesser god', perhaps individuals from a lower social class or with some form of disadvantage.
Since I haven't read every single story in detail, it's hard to name all the main characters. But typically, there are often ordinary humans who find themselves in extraordinary and terrifying situations. These characters are usually the ones through whom we experience the horror of the stories.
Maybe there's a group of characters. One could be a scientist who has discovered a way to reanimate corpses in a world where light novels blend science and magic. And there might be a moral compass character, like a priest, who opposes the idea of raising the dead and tries to stop it.
Without having read the 'the dead house crime novels' in detail, it's hard to say for certain. But often in crime novels, there are protagonists who are either investigators or people somehow connected to the crime scene. There might also be antagonists, perhaps the criminals themselves or those who are covering up the crimes.
For new horror readers, 'The Woman in Black' by Susan Hill is a great start. It's a classic - style ghost story that is not too overly gory but still very spooky. Another good one is 'The Ruins' by Scott Smith. It's about a group of tourists who get trapped in a place filled with a deadly and mysterious plant. 'The Grip of It' by Jac Jemc is also a good choice as it focuses on a couple who move into a house with a malevolent presence and the psychological toll it takes on them.
I would recommend 'Lost Souls' by Poppy Z. Brite. It's a dark and atmospheric horror novel that delves into the world of vampires in a different and more gritty way compared to the typical vampire stories. Then there's 'The Keep' by F. Paul Wilson. It has a great sense of mystery and horror set in an old castle. 'The Shuddering' by Ania Ahlborn is also a great pick. It's about a group of friends who encounter a terrifying presence in a remote cabin in the woods.
Some lesser known horror novels often have unique settings. For example, they might be set in remote, desolate places like abandoned asylums or old lighthouses. They also tend to play with different types of horror elements. Instead of just the typical ghosts or vampires, they could feature things like malevolent plants or cursed objects. Their characters are usually complex, not just simple victims. They might have their own secrets or motives that add to the overall horror of the story.
In 'Walking Dead Dead City Story', Negan is a key character. He has his own past actions and relationships that shape his role in this new part of the story. Maggie is also a main character. She has her own motives and goals, often in conflict with Negan's. There are also other characters who interact with them, but these two are among the most prominent as they drive the story forward through their actions and decisions in this zombie - filled world.
I'm not entirely sure, but I think there must be some brave survivors who fight against the zombies.
