I think the side characters that interact with the reborn demon lord are really interesting. For example, the young apprentice who befriends him. Their relationship shows the contrast between the demon lord's past and his new life. Also, the old enemy who now has to deal with this reborn version of the demon lord in a different way adds a lot of intrigue to the story.
In the 'The Greatest Demon Lord Is Reborn' light novel, the female mage who discovers the truth about the reborn demon lord is quite an interesting character.

Moreover, the old mentor figure from the demon lord's past life who might have some hidden secrets also makes for a very interesting character.
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.
Perhaps the people who interact with the reborn demon lord are interesting too. They might be ordinary folks who are unaware of his past. Their reactions to him and how they influence his new life could be very engaging. For example, a kind - hearted neighbor who befriends him without knowing his true origin.
The main themes in 'The Greatest Demon Lord Is Reborn' light novel include transformation. The character goes from being a feared demon lord to someone with a new chance at life. There's also the theme of self - discovery. He has to explore his new abilities and limitations in this reborn state. Additionally, the theme of morality comes into play as he decides whether to follow his old, perhaps more evil ways or embrace a new, more positive path.
The antagonist is often very interesting. In Assassin Reborn, the antagonist might be someone from the assassin's past who has also changed or someone who is threatened by the assassin's new - found power. Their motives and methods of trying to stop the protagonist can be full of twists and turns, making them a character to watch out for.
The slime protagonist is quite interesting. His transformation from a human to a slime and his unique growth process make him stand out.
Zenitsu is quite interesting. His cowardly nature at first, which is in contrast to his amazing lightning - based fighting skills when he's unconscious, creates a lot of comical and engaging moments in the light novel. Inosuke is also fascinating with his wild and boar - headed appearance and his brute - force fighting style.
The protagonist is usually quite interesting. They often have unique abilities or personalities that set them apart. Maybe a character who has a special power that no one else has. Another could be the mentor figure, if there is one, who has a lot of wisdom and a mysterious past.
I'm not sure about all the main characters. But of course, the demon lord is likely one of the main ones.
Another key character could be the mysterious figure who seems to have some knowledge of the Demon Lord's past and the reasons behind his retry. This character often appears at crucial moments, dropping hints and guiding the Demon Lord in a way, and their true identity is one of the mysteries that keeps readers interested.
Anos Voldigoad is definitely one of the most interesting. He has such a powerful presence and his nonchalant attitude towards many things is both amusing and intimidating. Misha Necron is also interesting. Her relationship with Anos and her own growth throughout the story add depth to the narrative.
In the 'Demon Lord Reincarnated as a Nobody' light novel, the primary character is the demon lord who has taken on a new, ordinary identity. Alongside him, there could be a young adventurer who befriends him, not realizing his true nature. There might also be an old wizard in the village who senses something different about him. And don't forget about the local tavern owner who serves him and becomes a part of his new life story, each character adding depth and complexity to the overall narrative.
