In this, the ninth Ranma 1/2 graphic novel, Shampoo takes Mousse to her bosom at last; a mailbox–impersonating rival named Tsubasa Kurenai vies with Ranma for the beauteous Ukyo; Akane meets Yoiko, the “good–girl” little sister Ryoga never knew he had; Soun and Genma tell the tale of the terrifying “Happo–Fire Burst”; and finally, after retrieving the scroll which contains the secret of his devastating final attack, his twembling disciples bid a fond “hasta la vista, pervert!” to their thwarted Master Happosai.
