Very friendly and cheerful, there isn't a single thing in the world that gets her down or any negative that she can't turn into a positive. Her positive attitude has been shown to be helpful, as it allows Ruby to act as the voice of reason in the mansion, while her friends tend to lose focus on real issues. Her positive outlook also makes Ruby very loyal to her friends and there's nothing she wouldn't do for any of them. She likes to have quiet time to write in her diary and knit.
