I don't know if this fits or not but the mc is the ex hero who was betrayed so, he is wrecking havoc and destroying the kindom/empire because why not. Sorry if it's not what you're looking for
Don't be put off by the cover. There is no romance plot whatsoever
no that works! i read this one already but thank you so much! that’s honestly a great suggestion
since u mentioned king's makes im assuming you dont mind bl so i recommned The Affairs of the Other World Depend on the Corporate Slave. i really like the economic aspects and the mc.
does anyone know any manhwa/manga that’s similar to overthrowing an empire?
or anything with a prince as a main character? maybe something like ffXV or Kings Maker/Code Geass? i’d prefer if romance wasnt really a major plot line but more so on the state of the empire.
