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'm terribly sorry.
أنا في غاية الأسف
Es tut mir schrecklich leid.
Lo siento mucho.
Lo siento mucho.
Je suis vraiment désolé.
Cette maladie est héréditaire,
È davvero una sventura.
Sinto muito...
Я очень сожалею.
