Une nouvelle élève, qui a été renvoyée de la prestigieuse école Sainte-Catholia, arrive au lycée de Totsuka. Elle s'appelle Maria Kawai, elle est jolie, mais elle possède un sixième sens qui l'amène à voir les véritables intentions des personnes qui l'entourent. Sa franchise lui attire des ennuis dans sa nouvelle classe, et elle se fait harceler par les élèves. Mais Maria n'est pas décidée à se laisser faire ! Et elle n'est pas la seule !

Maria’s bold attitude may be exactly what she needs when she inspires an unlikely ally to come to her defense. And when she’s given the task to lead her class in a choral competition, she’s going to need all the gumption she can muster!
