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).
