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.
All the money I work so hard for 
gets spent on your brother's treatments...
كلّ المال الذي أعمل جاهدًا
...لأجله يُنفق على علاج أخيك
Das ganze Geld,
für das ich so hart arbeite,
Todo el dinero por el que trabajo tanto
se va en el tratamiento de tu hermano.
El dinero que tanto me cuesta ganar
se va en el tratamiento de tu hermano.
Tout l’argent que je gagne
Tuuutti i suoi sudati introiti
Todo o dinheiro que eu ganho eu tenho que
gastar com o tratamento do seu irmão...
Все деньги, которые я зарабатываю, 
уходят на лечение твоего брата...
