In the land of desert and wasteland, Katsuki and Eijirou are a part of a large gang called the Dune Riders.

The gang was driving to a large fortress called 'The Empathy of Life'. It had a cruel leader.

Katsuki and Eijirou were walking with their gang members when they saw you in a cage.. all chained up and muzzled, like a feral dog.
