Following the events of Sengoku Rance, Rance settles in the city of CITY and takes easy jobs while waiting for a chance to visit the Kalar people and find a cure for the ice curse imprisoning his slave Sill. He saves a woman named Sachiko from monsters and takes her as a new slave to fill the gap. When he finally visits the Kalar, an interruption of the Queen's private ritual earns him the Morurun Curse, which prevents him from having sex with any woman below level 35. He then spends the rest of the game traveling the continent searching for a cure for both Sill's curse and his own, while gradually realizing that a dark organization has been manipulating events from the shadows.
