Cady is the main characther of the story. She’s the nerd at school who loves studying, because some day, she hopes to become a software engineer. She falls in love with Cornelius, a young 20-year-old inventor. Robert, the antagonist of the story, is her biological father, and her mother is Sheila. 

Cady has a slightly anti-teenager personality. She's not into the stuff that mist teens are into (fashion, makeup, boys, etc.) She is very logical and sensible but often tries to do everything herself without help. Her mother often restricts her freedom, which is what causes her to beg for independence. (Note: some of her audition lines have been changed due to the fact that I wasn’t sure what to put there at first, so don’t be surprised if you notice the other auditions have different lines.)
