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.
After all, we are family.
في النهاية، نحن عائلة
Immerhin sind wir doch eine Familie.
Después de todo, son mi familia.
Después de todo, sois mi familia.
On est une famille, après tout.
Del resto,
Afinal, somos uma família.
В конце концов, мы же одна семья.
