Rance 5D: The Lonely girl

The warrior Rance, his faithful slave Sill Plain and his not-quite-as-faithful pet Athena 2.0 are out adventuring in an attempt to earn money after Rance spent all of their finances playing around. Their travels lead them to a mysterious cave, in which all three become lost. Rance successfully reunites with Sill and, agitated over getting stuck and indifferent to Athena's well-being, attempts to exit the cave, only to find himself becoming even more lost in the process.
