In Cinderella Girls Theater skits, Yume is often depicted as being shy and easily embarrassed. She plays a "soothing green wind" character in Chika Yokoyama's magical girl TV show and uses an ocarina in the "Little Marching Band Girls" unit. After reading a story about calling forth fairies, she bought an ocarina with the hope of doing so but instead brought forth a group of band members who became her seventh member. With their help, Yume convinced Wakaba Kusakabe to join as the final member.
