An [i][[iDOLMASTER Cinderella Girls|iDOLM@STER Cinderella Girls]][/i] character in the Cool (Blue Diamond) category. Ryo is a horror movie and death metal fanatic, though she appreciates music genres like jazz and classical. She is a good friend of [[Shirasaka Koume]], as the two share many interests. While she enjoys horror, she tends to be bored by most horror films. That said, she isn't immune to fear like Koume and can be scared by ghosts.
She was a vocalist in a band, and in the anime, she was introduced as a member of [[Kimura Natsuki]] prospective band. However, she is a kind girl who cares about the other younger girls, like [[Sasaki Chie]] and [[Shirasaka Koume]], and how they feel. Her company often gets her into trouble, but she admits that she enjoys their antics as long as they end peacefully.
