Ranma and Ryoga found themselves alone in a war between three tribes at Jusenkyo, Genma having chickened out. They fought for their lives killing anyone who came close as they were attacked and ended up fighting Amazons near the springs. Ranma kills a red head who drowns and is knocked into the same spring. He turns into a copy of the Amazon, she drags Ryoga to safety. They are found by Amazons and they assume Ranma is Ruby, who accidentally persuades them Ryoga is her husband. Ruby’s mom gives her a powder to use on the food that makes them horny. Ranma and Ryoga make love and then head out for a war party the next day.
