11

Shampoo explains that, according to Chinese Amazon Law, if an Amazon is defeated by an outsider, and that outsider is a woman, then she must give that woman the Kiss of Death and promptly kill her. However, if the outsider is a man, then the Amazon must marry that man. Shampoo immediately starts fawning over Ranma, much to the anger and dismay of Akane, who furiously declares that her engagement to Ranma is cancelled. While Akane wonders whether or not Ranma's feelings for her are genuine, Ranma is torn between Shampoo's infatuation for his male form and bloodthirst for his female form. During school the next day, Shampoo discovers Ryoga in his pig form and decides to break into Ranma's class and feed him Ryoga. Akane immediately cries and snatches P-Chan away to resuscitate him. With another attempt to win Ranma over stolen by Akane, Shampoo gives Akane the Kiss of Death and challenges her to a battle in the school courtyard. Ranma is knocked out unconscious for the battle and ends up arriving only when it is over. He finds Akane unconscious but unharmed. When he wakes her up however, she has no idea who he is.
