Aileen overcame all the difficulties and got engaged with Claude. Just when she thought she found her happily ever after, she receives news that a demon named Ashtarte attacked a human village in the Mirchetta region. Sensing new dangers, Aileen infiltrates Mische Academy in the Grand Duchy of Mirchetta to investigate the situation. There, she meets James Charles, the last boss of Regalia of Saints, Demons, and Maidens 2 as well as the other quirky members of the student council.
I can't allow anyone to think that 
Lord Claude attacked a student!
!لا يمكنني أن أسمح لأحد بأن يظنّ أنّ كلود-ساما هاجم تلميذًا
Wenn Claude verdächtigt wird,
kann ich nicht untätig bleiben!
Je ne peux pas les laisser croire
que sire Claude attaque des élèves.
Non posso permettere che qualcuno 
sospetti che Claude attacchi gli studenti!
Não posso permitir que ninguém pense
que o Lorde Claude atacou uma aluna!
Не хватало ещё, чтобы в нападении
на ученицу… обвинили Клода!
