Rance VI - Collapse of Zeth

Sometime after Rance 5D... Broke as ever, Rance scrambles for odd jobs to stay afloat and ends up in the Magic Kingdom of Zeth for work. Rance is usually seen with his slave magician Sill in tow. However, in this realm of magic, the tables are turned. As a non-magician, Rance suffers from discrimination, while Sill enjoys a VIP status. Before long, Rance winds up behind bars. Beneath its facade of wealth and peace, Zeth is a kingdom where magicians rule with an iron fist, and those without magic face relentless oppression. Fed up with his own misfortunes, Rance joins the resistance, ready to flip the oppressive regime. With a facade of freeing the nation's people, Rance dives into a whirlwind of an adventure: he dishes out comeuppance to wicked magicians, rallies a band of girls to join his cause, and builds a harem, all while living it up on his quest for justice...

Set in the year LP0004, Rance and Sill travel to the Magic Kingdom of Zeth because they ran out of money once more. However, after offending a high-ranked minister and magic user named Radon, Rance is ironically thrown into the slave camp while his magic-using slave Sill is treated as a VIP. Vowing vengeance, he eventually escapes with the help of an underground resistance group called Ice Flame. Currently Zeth is an extremely un-equal country, with magic users being the only real citizens and the non-magic users treated much like slaves with virtually no rights. Only groups like Ice Flame and the more violent and extreme group known as Pentagon, and perhaps the mysterious King of Zeth try to fight this cruel status quo. Rance joins the group in order to get his revenge against the mages of the government of Zeth, and be reunited with Sill "while he's at it".
