As I haven't read 'I became his sweetheart novel', I can't name the main characters. But if it follows common patterns, there could be a protagonist who experiences a transformation in her/his love life and the love interest. There might also be supporting characters like friends or family members who play roles in their relationship development.
There's no way to tell without reading the novel. However, in a typical story like this, we might expect a male and a female lead. The male could be a strong - willed person and the female, the one who becomes his sweetheart, might be a kind - hearted and gentle character. But again, this is just speculation.
I don't know as I haven't read the novel. But usually, there would be the character who becomes the sweetheart and the other person she/he is in a relationship with.
I'm not sure specifically as I haven't read this novel. But generally, it might be about a relationship where the protagonist becomes someone's sweetheart, perhaps involving the development of their love, the challenges they face in the relationship, and how their feelings for each other grow.
The main character, of course, is the one who experiences the day of becoming a god. There could be a mentor - like figure in the story. This person might guide the protagonist in understanding their new powers or the new world they are entering. And there may be an antagonist, someone who either opposes the protagonist's new - found status or tries to use it for their own evil purposes.
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.
Since I haven't read the novel, I can't be certain. But there would probably be the protagonist, the despised granddaughter herself. There might also be her family members who are involved in treating her poorly or are part of the reason she is in this situation, like her grandparents, parents, or siblings.
I don't know specifically since I haven't read the novel, but it's likely to have a protagonist who is the one becoming a god.
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 who the author of 'his sweetheart luna' is. You can try searching for it on the Internet using search engines like Google. Just type in the name of the novel and 'author' and you might find the relevant information.
The main characters would include the stepmom who has to navigate her new role. The hero, who is on a path of growth and heroism. Then there could be other supporting characters like the hero's friends or mentors. Maybe there's an antagonist who tries to disrupt the family or the hero's journey, which would also make that character important in the story.
As I haven't read it, it's hard to say for sure. But likely the main character is the chef themselves. There may also be the Dragon King, who would be an important figure in the story as the chef is working for them. And perhaps there are other dragons or creatures in the dragon king's court who interact with the chef, like the dragon guards or advisers.
Obviously, one of the main characters is the woman who becomes the hero's stepmother. And of course, the hero himself. There may also be the hero's father, who is the link between the stepmother and the hero.
