Along with the memories of her previous life, she is now the villainess Wilhelmina Vollmer who tore the relationship between the hero and the heroine... However, Mina, who left the marquis's house 8 years ago, now lives as a commoner and has no relationship with the nobility. This is a deviation from the original story.

But due to a curse invoking plague and monsters to ravage the country, the school has enlisted commoners to join the magical arts training.
