Summary: Have you ever wondered what made the characters the way they are? Well wonder no longer for here is the tell all back stories for those memorable characters.
We know how the characters in the Ranma manga are now but besides a few glimpses into their past we don't know what made them the way they are. So I thought maybe write a story that tells how the characters came to be the way they are.
While I have a few ideas, this is mostly brainstorming/free writing. I'll use the Kuno family as the first idea. There are some things told in the manga. Such as something happened to their mother, Kodachi cooks for herself and her brother, the father had not been fixated on America prior to his leaving, Kuno senior left them by themselves for more than three years, etc.
This idea could start with whatever happened to Tatewaki and Kodachi's mother, be it her dying or just leaving them. Than the fic shows Tatewaki and Kodachi both wondering if it is because of something they did, so they try to become the best. Tatewaki tries to take upon the virtues of a samurai and Kodachi throws herself into gymnastics with the need to win, to the point she will do anything to do so. Time passes and their father becomes more and more unhinged until one day he just leaves them. Suddenly a 14 year old Tatewaki and a 13 year old Kodachi are left alone to take care of themselves. This does not go well for Tatewaki and Kodachi. He tries to control her after their father leaves them because he thinks he is protecting her and not understanding that is not how she views it. Kodachi feeling that Tatewaki is trying to lord it over her and control everything she does so she lashes out against him. This leads to them arguing and fighting until it reaches the point in which Kodachi start to regularly add sleeping powders to his food. Then we follow Tatewaki and Kodachi's lives until shortly after they meet and fall for Ranma (showing what Ranma means to them and how he fills a hole in their lives).
Instead of the Kuno's maybe do Ukyo. Start with her friendship with Ranma and daydreams about marrying him. Then show her being abandoned by her friend and the pain it causes her, not knowing why they left her. Than show her being ridiculed by the mean children in the neighborhood, particularly those she talked about Ranma to. Her being pitied by her elders. Her deciding that she will never love another man and throwing herself into her training. Show bits and pieces until after Ranma is back into her life, not knowing the pain he caused her and fighting with his fiancee. Deciding that she was wrong and that she wants to marry Ranma and those dreams she had could still come true.
This could be done for any and all of the characters.
