Continuous eating escape incidents that occur one after another in the town. The criminal was the martial artist sisters (Natsume, Kurumi) who are continuing their wandering journey in search of the father of a farewell martial artist. By chance, Akane became acquainted with the two because she shared the food with the walnuts, and the two who felt that they were indebted to them gave back, so they rushed to the Tendou family dojo as it was. According to the story, they are aiming to be the strongest female indiscriminate fighter in the world, and at the same time they are looking for a father who split up at an early age. And his father's name is Soun Tendo... Sakumo denies that he doesn't remember, but the sisters say there is evidence and show a photo with a letter of comfort. After that, the sisters and Akane decided to fight with Natsume, Kurumi vs Ranma, and Akane's team, taking the mark of the Tendou Dojo.
