Most BSD light novels often have complex characters. Since they are based on literary figures, they bring in the depth and complexity of those original personas. For example, a character might have the same traits as a famous writer but with a unique twist for the BSD universe.
Well, from what I gather, in 'Corruption in Democracy: An American Novel', the corruption could be shown in the way money influences elections. Big donors might have too much sway over politicians. This can lead to policies that are not in the best interest of the general public but rather those who funded the campaigns. Also, there could be nepotism or cronyism within the political and administrative systems.
The appeal of all BSD novels lies in their ability to create immersive worlds. They draw readers in with their unique concepts and engaging storylines. For instance, the way they handle character relationships is very captivating. The conflicts and reconciliations between characters make for a great read.
Honestly, there's no definite answer on when the BSD manga will end. It all comes down to various factors like the author's inspiration, the popularity of the series, and the publisher's decisions.
