I don't know, as I haven't read this light novel.
I'm not sure specifically as I haven't read it. But generally, it might be about a character's journey to becoming a legend over the course of a decade.
Power and its consequences could be a theme. As the character gains power over the decade and becomes a legend, there are probably implications of how that power affects them and those around them. Also, the theme of friendship or relationships might be present. Along the journey to becoming a legend, the character may have made allies or had relationships that influenced their path.
There's 'That Time I Got Reincarnated as a Slime'. In this light novel, the main character, who starts off in a rather unassuming state, gradually becomes a powerful and legendary figure. It shares the concept of growth and achieving a legendary status over time, which could be related to 'I became a legend a decade later light novel'.
The main characters in this light novel could be a diverse group. There might be a young hero who discovers their latent power, and around them, there could be a group of comrades. Some might be strong fighters, others could be more intelligent strategists, all coming together to support the main character's rise to the top.
Rimuru Tempest is the main character. He was originally a human but got reincarnated as a slime. His character is really appealing as he has a kind heart and uses his new slime - based powers to build a community and face various threats.
I don't know specifically as I haven't read the novel. It could be a lone hero type character.
Since I haven't read the 'became king after being bitten' light novel, it's hard to say who the main characters are. But it's likely that there's the protagonist who becomes the king after being bitten. There might also be antagonists who oppose his rise to power, like rival nobles or evil sorcerers.
Tsukasa Kadoya, who is Kamen Rider Decade, is a key character. Then there are the other Kamen Riders from different worlds that he encounters. For example, Kamen Rider Kuuga. Their interactions with Decade shape the story. Also, Natsumi Hikari plays an important role as she is often involved in Decade's adventures and provides a different perspective compared to the more combat - oriented Decade.
I'm not sure specifically as I haven't read this particular light novel in detail. But usually in a light novel about immortals, there might be characters who are on a journey to gain immortality or those who already are immortals and have some special powers.
There is a wizard who is also an important character. He often helps the main swordsman with his magic powers, especially in difficult battles. And there is a female character, who is strong - willed and a great fighter herself. She has her own goals and sometimes clashes with the main character but also becomes his ally at crucial times.
