What are the main themes in 'The Greatest Demon Lord Is Reborn' light novel?

The main character is the demon lord himself. He is a powerful and complex figure. There are also other characters like the various races' leaders who interact with him, such as the elven queen who has her own motives and agendas when dealing with the demon lord.

One of the main themes could be redemption. Since the demon lord is reborn as a nobody, he might have a chance to atone for his past deeds. Another theme could be self - discovery as he has to figure out who he is in this new, ordinary form. And also, there might be a theme of adapting to a new life, which is very different from his previous life as a powerful demon lord.

The titular greatest demon lord is definitely one of the most interesting. His journey from being a powerful and feared figure to being reborn and having to adapt is captivating.

One of the main themes is power and its consequences. The protagonist has great power and has to deal with how it affects those around him and the world he's in.

One main theme could be redemption. Since the demon king is reborn, he might be seeking to atone for his past sins or mistakes. Another theme could be power struggle. Even as a reborn entity, he may still have to fight for his place in the new world.

As I'm not familiar with this specific light novel, it's hard to say who the main characters are. But it's likely that there is a demon lord character at the center of the story. There may also be characters who oppose the demon lord, like a group of brave warriors or mages. Maybe there's a special character who has a connection to the demon lord from the past or something like that.

Well, I think courage is a main theme. The protagonist is likely to face numerous difficulties and fears in the journey to defeat the demon lord for their daughter. Another theme could be sacrifice. There may be situations where the protagonist has to give up something valuable in order to achieve the goal of protecting their daughter and defeating the enemy. And, of course, the theme of family bonds is central, as it's all about doing this for the daughter.
