Story
You can tell witch training is not going swimmingly for the young sorceresses Akko, Lotte, and Sucy—they face expulsion for screwing up one class too many, and their only way out is if they successfully organize their academy's annual parade through a nearby town. But when they stumble upon the momentous discovery that the objective of the parade is to humiliate witches and commemorate their past subjugation, Akko decides it is time for a change: It is time to show the world how fantastic modern witches truly are!
