Since I haven't read it, I can't say for sure. But based on the title, it seems that a reincarnated sage and a girl are important characters.
Given the title 'tensei kenja wa musume to kurasu light novel', it's likely that the main characters are the 'tensei kenja' which is the reincarnated sage and the'musume' which is the girl. There might be other supporting characters as well, perhaps some friends or foes that they encounter in their journey together. But the story is probably centered around the interactions between this sage and the girl.
I don't have direct knowledge of the main characters in this light novel. But from what the title implies, the two main characters are probably a reincarnated wise man (the 'tensei kenja') and a girl (the'musume'). They are likely to be the focus of the story, with their relationship, actions, and development driving the plot forward. There could also be other characters related to their world, like the people in the place where they live ('kurasu'), who might play important roles in the story as well.
I'm not sure exactly as I haven't read it in detail. But generally, light novels often revolve around unique characters and their relationships. Maybe it's about a reincarnated sage and his life with a girl.
The main character is likely the reincarnated sage. Since the title has 'tensei kenja' which means reincarnated sage, this character should be central to the story. There may also be other characters like the people the sage meets in the isekai world, such as local villagers, other adventurers, or perhaps even some magical beings.
Since I haven't read the novel specifically, I can't say for sure. But it's likely to have the reincarnated sage as a main character. There may also be characters who help or oppose the sage in their journey.
I don't know for sure, but based on the title, it seems that there is a 'kenja' (sage) and his or her 'deshi' (disciple).
The primary character is Shin Wolford. He's a key figure as he brings his knowledge from his previous life into the new world of the 'Kenja no Mago' light novel. There are also other characters like his family members in the new world, his friends and allies he makes during his adventures, like Sizilien von Klauen, who play important roles in the story as well.
The title indicates that the summoned sage is a key character. There may also be other characters like those who summoned him, or characters he meets in the isekai world such as local inhabitants, other adventurers, or even potential foes.
The 'asobinin wa kenja light novel' could potentially have a unique story, perhaps involving a protagonist with special abilities or an interesting fantasy world. However, without actually reading it, it's hard to say for sure what makes it stand out.
The main characters in the 'Monster Musume no Oishasan' light novel would include the protagonist, who might be in a position of providing care or assistance. Among the monster girls, there could be one that is the leader or spokesperson of sorts for the group. Another could be the one who causes the most trouble at first but later becomes an important part of the story. There may be a shy monster girl who slowly opens up as the story progresses. But again, this is all speculation without a full read of the novel.
Power and its implications are also important. He gains certain powers and has to learn how to use them responsibly and also deal with the consequences of having power in a world full of different factions and interests. In this light novel, there are often situations where power can be both a tool for good and a source of trouble.
The slime is surely one of the main characters. It could be accompanied by some humanoid or non - humanoid characters that it meets during its adventures. For example, there might be a wise wizard - like character who helps the slime understand its powers better, or a fierce warrior who becomes its ally or rival. Also, there could be some evil - minded creatures that serve as antagonists in the story.
