Akuma to Love Song

Touzuka High School is a public school with a pretty low grade point average. One day, a girl who has been expelled from the state's top class St.Katria Girls School transfers in.... Her name is Kawai Maria. The reason of her expulsion was "violence against the teacher." Because of her non-adorned, straight comments, Maria starts to become isolated from her class....What is hidden in her past and what will happen to her?
