Inheriting her father's pitching arm, Ryo has an innate pitching ability. She is left-handed player just like her father. She originally planned not to go to high school because she wanted to help support her mother at the family's Oden shop, but she is recruited to the Kisaragi Girls' High School to be the foundation of the new baseball team. Before playing for Kisaragi, she often played as relief pitcher for a local sandlot baseball team, the Wildcats.
