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.
I'm not super familiar with this specific 'raising the dead light novels'. But generally, in light novels, interesting characters are a key aspect. Maybe these novels have unique characters who can raise the dead, like a necromancer with a complex backstory and moral code.
Since I haven't read the 'raising the dead' web novel, I can only guess. It could be a horror - themed web novel where raising the dead has unforeseen and terrifying consequences. Maybe the dead come back wrong, not as they were in life, and start causing chaos. Or it could be a more adventurous take on the idea, where a group of adventurers seek to raise the dead for some noble cause, like finding a lost civilization's secrets that only the dead know, and they have to face numerous challenges along the way.
In a web novel titled 'raising the dead', the main characters could be diverse. There could be a young apprentice who is learning the art of raising the dead from an older, more experienced mentor. The mentor might be a wise but somewhat secretive figure, hiding some dark secrets about the true nature of raising the dead. And then there could be a group of antagonists who oppose the idea of raising the dead, either for moral or power - related reasons. They could be a religious order or a group of powerful mages who see it as a disruption to the natural order.
The most important character is the Shield Hero. He has a complex personality, being initially naive but becoming more cynical due to the treatment he receives. Raphtalia is vital. She starts as a slave but becomes a strong warrior under the Shield Hero's guidance. Filo, a bird - like creature, is also key. She provides comic relief at times and is a strong fighter. Additionally, the villains and side characters also contribute to the overall story, such as the king who initially mistreats the Shield Hero.
One of the main themes is perseverance. The shield hero has to face a lot of hardships and discrimination but still keeps going. Another theme is growth, as he gradually becomes stronger both in power and in character throughout the story.
The plot involves a system that selects girls to become magical girls. However, things take a dark turn as the competition among them becomes deadly. It shows how the initially innocent concept of being a magical girl gets corrupted in a harsh and unforgiving scenario.
The Akatsuki could also be the main antagonists. They might see the power of raising the dead as a way to achieve their goals. For example, Pain could use the raised dead to spread fear and chaos, or to try and find a way to resurrect Nagato. And they would definitely be a formidable force against Naruto if they were after this power.
