Sometimes, there are customers who come to the blacksmith. They could be knights in need of a magical sword or a noblewoman looking for a special piece of jewelry. Their requests and interactions with the blacksmith drive the plot forward.
There might also be a young apprentice. For example, in some novels, the apprentice learns from the master blacksmith, and their relationship is an important part of the story. The apprentice could be naive at first but grows under the guidance of the master.
I'm not entirely sure as I haven't read the novel in full, but I would assume the blacksmith is a main character. Since it's called 'the sacred blacksmith light novel', the person with the blacksmithing skills must play a crucial role.
Cecily Cambell is one of the main characters. She is a knight - in - training with a strong sense of justice.
There could be the blacksmith's mentor if it involves a story of his apprenticeship. There might also be some rivals in the blacksmithing business. For example, another blacksmith in town who is jealous of our main blacksmith's skills and tries to undermine him. And of course, there could be characters from the local community who depend on the blacksmith's work, like a knight who needs a new sword or a farmer who needs a new plow.
The main characters usually include the dragonborn, who is the central figure with dragon - like abilities such as breathing fire or having super strength. There might also be a wise old mentor figure, perhaps an elf or an ancient wizard, who guides the dragonborn on their journey. And then there could be a group of friends or allies, like a brave knight, a clever thief, and a kind - hearted healer. They all work together to face the challenges that come their way, whether it's fighting against an evil dragon or a dark sorcerer who wants to take over the world.
Often, there is the paladin themselves as the main character.
Often, there are investigators. They are the ones who start to dig into the strange happenings related to Cthulhu. For example, a detective who notices a series of disappearances that seem to be linked to something far more sinister than normal crime.
Often, the main character is a shrewd and wealthy individual in the game world.
There could be a male lead who is an ordinary guy but gets thrown into an extraordinary situation, like being transported to a fantasy world. He then makes friends and finds his own version of a happy life there. The characters around him, such as a wise old mentor or a spunky sidekick, also play important roles in his journey.
The protagonist is the blacksmith. He's the central figure around which the story unfolds. He's likely to be a character with a lot of determination to prove that his occupation isn't as weak as it seems.
In some returner light novels, there are also side characters who play important roles. For example, in 'Returner's Magic Should Be Special', the friends and allies of the returner help him on his journey, and they have their own unique personalities and abilities that complement the returner's.
