Ryo is both the Pitcher and captain of the Kisaragi Girls High Baseball Team: 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 releif pitcher for a local sandlot baseball team, the Wildcats. She is also in love with Kisaragi Boys High Baseball teams star hitter Hiroki Takasugi. The ending strongly hints that she and Hiroki will get together.
