Rance IX: Helman Kakumei by Alice Soft jap

The Helman Empire is the oldest of the countries on the continent, as well as being the most powerful for a long time. However, corruption had ruined the nation and most live in extreme poverty. It felt like it was only a matter of time before an internal revolt would break out or they would be invaded by a neighbouring country. Then the former Prince Patton Misnarge, who had disappeared after failing to conquer a neighbouring country, returned after training hard to keep his promise of bringing back glory to his country. To aid in his revolution, he recruited the best and most courageous men that he had met during his travels, including the most powerful warrior Rance.
