Holy Girls Square Academy is a school that trains professional star performers, and only girls who pass auditions at Girls studios around the country can enroll. Students form teams and practice every day, hoping to perform at the Girls' Arena, the academy's biggest event, held once a year. Only a single team earns a place on that stage, so every group pushes hard for the chance. This short-format comedy with music centers on the dreams and friendships of these aspiring performers.
