After her mother and father died, Shiori and her little brother Shu were taken in by their uncle. Soon after, Shu was hospitalized with a hereditary disease, and Shiori was sent to the school as punishment for fighting back against her uncle's abuse. Meanwhile, Hibiki has taken over leadership of class four, and Hyo appears before him, to make him an offer he cannot refuse.
I could fulfill a wish I've 
had since middle school.
يمكنني أن أحقّق رغبةً كانت تعتريني منذ أيّام الإعدادية
könnte ich mir einen Wunsch erfüllen,
den ich seit der Mittelschule hege.
et ce soir, je vais pas me gêner.
che pensavo di voler realizzare stanotte.
eu poderia realizar um desejo
que eu tenho desde o ginásio.
и понял, что мог бы исполнить 
свою мечту.
