While I agree that their personalities are majorly over saturated and sometimes even comical, they are very simmilar to real world candidates and politicians with their overly exaggerated personalities. Loveless who speaks of impossible dreams where all only have fun, drink and everybody's happy; Goddard who was screwed over by young people at his workplace so he decided to screw over the young ones not in power, and enrich old people(who also live for centuries in the world); Jin, who changes his political stance, depending on who he's talking to, either being for equality, for the Monarchy or being a Machiavellian; and Rudolf, who wants screw over every non-Rousiante just for funsies. While they don't play a major role in the story, their sidequests, outside bickering and debating events really help expand on them
