Saaya is the oldest of three children in her family; she has a younger brother named Jun, and a younger sister named Sana. Saaya's family own the Yamabuki Bakery, at which she helps out, even during the school term.
Saaya used to play in a girls' band called CHiSPA when she was in middle school, but quit because she didn't want to burden her bandmates and her family due to an incident that happened before a past performance. But thanks to Kasumi, who never gave up on her, and her mother's support, she regained her passion for music and her desire to perform in a band, thus became the last member of Poppin'Party to join.
Saaya has slanted blue eyes and long, curly brown hair worn in a high ponytail, usually tied up in a ribbon. She has spread-out bangs and shoulder-length curled forelocks. She wears a long pale yellow skirt with a white, frilly off-the-shoulder top.
A kind, hardworking person who cares deeply about her friends, Saaya often lends an ear to Kasumi and Rimi. She is generally level-headed and easygoing, and is like an 'older sister' to the other girls, always willing to help them out in hard times.
