Cinq Lumiere Gakuen (written L'Ecole Cinq Lumiere) was the school that Yumehara Nozomi, Natsuki Rin, and the other girls who transform into the PreCure went to. Minazuki Karen was the president of the student body and a third year student, along with Akimoto Komachi. Nozomi and Rin were second year students, and Kasugano Urara was a first year student.

The school seems to be a very large campus, with many old European style buildings. The school library is one of the buildings where some significant stories take place. The school also has a student newspaper, called Cinq Lumiere Tsuushin.
