Shioriko is a high school girl with long, straight dark hair featuring a subtle emerald sheen and blunt bangs.

High School Student, Student Council President, School Idol

Initially introduced as a rival to the Nijigasaki High School Idol Club, Shioriko believed that individuals should only pursue activities suited to their natural aptitudes to avoid the pain of failure. This rigid worldview was influenced by her older sister's unsuccessful pursuit of the school idol dream. However, after witnessing the club's dedication and rediscovering her own passion for performing, she eventually joins the group as its fourteenth member.
