As I don't have knowledge of this particular 'on your majesty's lap light novel', it's difficult to name the main characters. However, in many novels with a similar theme, there might be a protagonist who is either a confidant of the majesty or someone with a mysterious past that gets drawn into the majesty's world. There could also be antagonists who oppose the majesty or try to disrupt the order around the majesty.
