Everybody involved though that it had ended then. They went on with their lives, found their pairs, grew their own families and never, ever looked behind...
But when Ranma suddenly develops an eerie ability to create and control flames during the fight with Saffron, other mounting clues point to the horrifying fact that the legacy of Mouri Kouran may NOT have had died with him (if you ever read Flame of Recca, you'll notice that Henge (Kurei's female clone) was never truly shown to be dead, as they began their final batlle -before- that. An amalgam of their broken and twisted personalities could very well have survived into that body…). Even worse, it looks like the Ura Uruha is once again on the move. Now, Ranma must learn the forgotten art of the Hokage ninjas from his great-grandfather on his mother's side, Hanabishi Recca! And what is this about being family with the Kuonji and Hibikis? What?! Their actually descendants of Kurei and Kaoru?! They learned the art of Madogu creating?!
