Since there are numerous 'noblesse oblige light novel' out there, it's difficult to name the exact main characters. But typically, you'll find a central noble figure. This character could be a young heir or heiress to a noble title, new to their responsibilities and learning about noblesse oblige. There might also be other nobles who serve as foils to this main character, either more strict or more lax in their interpretation of noblesse oblige. Additionally, commoner characters could be present, who either look up to the noble with the sense of obligation or are skeptical of it, and these interactions can shape the story and the noble's character development.
One of the most interesting characters has to be Ainz Ooal Gown. He is constantly trying to navigate his new role as an all - powerful overlord while still having memories and emotions from his human life. Then there's Mare Bello Fiore. His shy and gentle nature is in contrast to the often brutal world of Overlord. It's interesting to see how he copes with the actions and orders within Ainz's regime. And of course, Cocytus, with his strict sense of honor and his military - like mindset, is also a very engaging character in the story.
The main themes include friendship. The relationships between the characters show how they support and rely on each other. There's also the theme of justice.
