Suzuya Riko

She is a childhood friend of Ibuki Akane, the head of the Red Lily dormitory, and serves as the deputy head of the dormitory. Although she and Akane compete in different sports, they are good rivals and close friends. However, Riko gave up on sports in her first year due to a chronic illness. Since then, she has chosen to contribute to the Red Lily dormitory as a manager. She has known Akane for a long time and is a valuable person who can express her opinions to Akane head-on. Riko's kind and devoted support as a manager is a comfort to the students who are exhausted by the excessive training Akane imposes on them.
