About
Four second-year students at Luminous Academy, a high school for training idols. In their first year, they performed in separate units: Nagisa and Toru in "Nocturne," and Shizuki and Reiga in "Etoile." In the spring of their second year, a sudden change in school policy restricts activities for any unit with fewer than four members. Now in the same class, the four begin performing together as Etoile Nocturne (Eto-Noku). This is the story of their journey to becoming national idols. Upon meeting certain criteria by graduation, they can officially debut under Luminous Production (Lumi-Pro). ੈ✧˚. Regarding Guest Feel free to define them as you like!
