Trivia

 * It has many differences that make it stand out from previous main schools in the Aikatsu! franchise.
 * It is a regular institution that does not specifically educate idols. To that end, the students' track suits don't come in different colors to denote their idol types.
 * It is co-educational, meaning the male and female student bodies are intermixed.
 * The female students are shown to be able to choose between wearing a skirt or shorts as part of their uniform.
 * It is revealed this is due to an overturned school regulation as suggested by Kyōko Umekōji.
 * It lacks an associated middle school.
 * Underneath the school's maintenance building, there is an abandoned storage room which was turned into a secret hideout of sorts by Kyōko Umekōji.
 * The only others to know about this room are Mao Otoha, Shiori Motoya, and Ruli Tamaki.
