Viola

The Duke's younger sister. A girl of an age interested in sweets and romance. She has a reckless personality and regularly visits the separate residence where The Duke lives, which her mother forbids. She hardly remembers The Duke as he had been living in the separate residence since she was very young. She is easygoing with everyone, but she gets nervous around her beloved Rob, which sometimes makes it hard for her to speak properly. She is skilled at playing the violin.
