Once hailed as a prestigious institution, Bernstein Magic Academy has now fallen into disgrace, becoming a problem school overrun with delinquent students.
Glenn, a yankee (delinquent) student at Bernstein, lives a dull, uneventful life—expecting nothing from anyone, and with no one expecting anything from him.

One day, a mysterious witch named Astera arrives at the school as a newly appointed teacher.
Dismissing her as just another all-talk instructor, Glenn challenges her to a one-on-one duel with the right to conduct the class at stake—but…!

A magical comedy featuring a delinquent magic student and a witch teacher!
