One year has passed since Rurumo and Kouta were caught up in the demonic coup d'état. Now, three new-generation witches have descended to the human world. They are bottom-rank witches on the verge of expulsion, having failed their missions time and time again. What kind of task—one that could determine the very future of the demon world—has been entrusted to them!?

...Or so it sounds, but witch Lushika is absolutely thrilled at the chance to finally experience life on Earth. Her mission: to collect "Magic Letters" (Majimoji)—and the stage is none other than a junior high school! While pretending to be an ordinary schoolgirl, can this dropout witch really fulfill her duty without messing it all up!?
