Sometime after Ranma's Girl Days training has been concluded, Ranma and Akane are doing a bit of window shopping. Ranma is in her girl form as one of the ongoing training days. Wandering into a strange shop, the owner offers Ranma the chance of excitement and adventure! Surprisingly enough Ranma is not at all interested. But destiny will not be denied and a chain that accidentally falls into Akane's bag transports the pair to the world of the Slayers. Where before long they meet up with another redhead. Maybe a bit shorter, different coloured eyes and a lot less... How do martial arts compare to magic anyway?
Ranma (in girl form) and Akane is tranported to the world of Slayers in which they bump and team up with Lina and her gang. Oh my. The trouble these 2 groups can get into.
It's after the Girl Days saga and Ranma and Akane are shopping. Then they enounter a magical pendant and are swept off to another world, a world they share with another destructive redhead with an insatiable appetite. Hey Lina, meet your perfect body... and the guy who's wearing it.
