Each character could have their own unique personality, backstory, and motivation that adds depth to the story.
In many light novels, the characters are what make the story engaging. In the 'Black Iron Light Novel', there could be a protagonist with a unique ability related to black iron. This ability could set them apart from others and attract the attention of both friends and foes. There might also be an antagonist who wants to use black iron for their own evil purposes. And then there are the supporting characters, who could be from different backgrounds and bring different perspectives to the story. For instance, a wandering merchant who has heard rumors about black iron and shares valuable information with the main characters, or a noble who is interested in the political implications of the discovery of black iron.

Sebastian is definitely one of the most interesting. His demonic nature and his perfect butler facade make him a complex character. Ciel, too, with his determination for revenge and his dual nature of a young boy and a shrewd master, is very engaging.
For me, Roberta is an extremely interesting character. Her unwavering loyalty and her incredible combat skills make her a force to be reckoned with. Her quest for revenge is a central part of her character arc. Then there's Eda, the undercover CIA agent. Her double - dealing and her ability to blend in with the criminal element while having her own agenda are really cool. And of course, Revy. She's the heart and soul of the action in a way. Her internal struggle with her own demons while being this badass gunfighter is what makes her so captivating.
