The entrance ceremony of the magic school. It reminds her of a spin-off novel that depicts the world after the popular otome game. 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. She thought that she would be cut off from the story and that she would be able to live her school life freely. But due to a curse invoking plague and monsters to ravage the country, the school has enlisted commoners to join the magical arts training.
