Invertia was a meteor storm that caused an unprecedented disaster during the 20th century. Because of this disaster, numerous cities around the world were destroyed. However, within the meteor, an unknown element called mana was discovered. It allowed human technology to make rapid strides giving rise to a new species of super-powered humans, the Star Pulse Generation (Genestella). The Festas (Star Warrior Festivals) host battles between Genestella at a city of six academies called “Rikka,” also commonly known as “Asterisk.” Scholarship student Ayato Amagiri transferred into Seidōkan Academy in order to fulfill his own wish, swearing he too will fight in this city. Upon Rikka, the academy-city above water, or what many call the “Asterisk,” students of the six schools prepare for the Festa. These annual comprehensive battle tournaments are held on a worldwide scale and each of the six schools place their hopes in their teams to bring them victory. In the Phoenix Festa (tag-team battle) category, Seidoukan Academy's Ayato Amagiri takes up the challenge along with his partner Julis, the Witch of the Resplendent Flames (Glühen Rose).
