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...
