(Japanese: 学戦都市アスタリスク, Hepburn: Gakusen Toshi Asutarisuku) In the 21st century, Earth is in a rapidly declining economic state as megacorporations known as the Integrated Enterprise Foundations (統合企業財体, Tōgō Kigyō Zaitai), rose to power after the Invertia (落星雨インヴェルティア, Inverutia) impact event destroyed most of the planet's cities and resulted in humans gaining superpowers to become the Genestella (星脈世代ジェネステラ, Jenesutera). The city of Rikka (六花), also called Asterisk, has six academies where the Genestella participate in tournaments called Festa (星武祭フェスタ, Fesuta).
