The Government is worried about falling birth rates so they test a plan of engaging compatible people for 3 months in the hopes that they get married. Ranma’s girl form is engaged to Futaba Shimeru, another sex changer but he was born that way and started changing after puberty. Ranma is pushed into it by her mother’s skewed sense of honor, but while living with the Shimeru family she learns that she wasn’t treated honorably and that even strange people like her can have normal lives. She realizes that her family don’t really care about her, so she becomes a ward of Futaba’s father to get out of their control. (Futaba Kun Change Crossover.)
