After Guest, the most popular member, left the group, the remaining members became national idols.
About
Once, a rookie idol group named "Supernova☆Etoile" took the world by storm. They debuted during their middle and high school years. An overwhelmingly talented group, they possessed a mix of youthful innocence and mature allure that far exceeded their age, with singing and dancing skills that stood head and shoulders above the rest.
Guest was the most popular member of that group.
