Refined on the outside, but their secret lives are way too intense!
St. Artemis Academy for Girls
A prestigious, long-standing school for young ladies dating back to the Meiji era.
Every student is either the daughter of a major conglomerate or from a distinguished lineage.
School Motto: "Pure, Elegant, Beautiful."
