Ruby is a girl who can find happiness in anything. "Look on the bright side" is a phrase she chants like a mantra, and it serves her well. There isn't a single thing in the world that gets her down or a single 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 tends to lose focus on real issues. Ruby also has a crush on Skull Boy, who is one of her friends. Her upbeat outlook also makes Ruby very loyal to her friends and there's almost nothing she wouldn't do for any of them. She likes to have quiet time to write in her diary and sew.
