Ranma ½ (2024)

Ranma realizes that Akane is suffering from selective amnesia, as she only has no memories or recollections of just Ranma. He ends up consulting Dr. Tofu on what Shampoo might have done to Akane during their fight, and Dr. Tofu explains that Shampoo used the infamous Shiatsu technique. Genma, who was passing by, witnessed the entire ordeal. He explains that the technique involves applying various shampoos and other Chinese medicinal herbs on the head at certain acupressure points in order to erase selective memories. This can also be reversed by applying the specific Shampoo Blend 119. Ranma decides to journey to China and purchase Blend 119 from a pharmacy, only to encounter Shampoo wielding Blend 119. After a scuffle, she agrees to give him Blend 119 under the condition that Ranma kills female Ranma (still unaware that they're the same person). Back at the Dojo, Ranma begs Ryoga to severely beat him up so that his battered body can be transformed and used as evidence of his female form's death. Ryoga refuses, but Soun and Genma oblige. Akane intervenes, demanding to know the cause of the commotion, and in a fit of rage, Ranma calls her "un-cute" (a common phrase he uses against her). This triggers a shock reaction from Akane. Ranma realizes that uttering familiar phrases will trigger the deep buried memory of Ranma within Akane. He starts name-calling her the various things he tells her that she is ("unsexy", "tomboy", "built like a brick"), leading to Akane finally remembering Ranma. Shampoo arrives, and upon discovering that Akane has regained her memories of Ranma, she attempts to kill Akane. Ranma stops her and reveals his secret to Shampoo, transforming into his female form in front of her. At first, Shampoo attempts to kill Ranma in a fit of rage, but then completely breaks down into tears and leaves, declaring that her and Ranma "will never meet again". (Source: Wikipedia)
