On the day of the Tennomifune Academy entrance ceremony, in the class 1-7 classroom, Hanakoizumi Anne (Hanako), Hibarigaoka Ruri (Hibar), and Kumegawa Botan (Botan) are told by their homeroom teacher Kodaira-sensei that they are unfortunate and unhappy students.
The goal of the students of class 1-7, who are burdened by a variety of forms of misfortune, is to become happy.
The three girls have trouble accepting their circumstances, but they're immediately given an unexpected assignment...!
Oh, my! Then you won't report 
me to the authorities?
يا للهول! ألن تبلِّغا عنّي للسلطات المعنية إذاً؟
Oh! Ihr werdet also keine
rechtlichen Maßnahmen ergreifen?
¡Cielos! ¿Significa que no me denunciarán?
¡Cielos! ¿Significa eso que no me denunciareis?
Alors, vous aurez la bonté
de ne pas porter plainte ?
Oh! Quindi non mi denuncerete alle autorità?
Nossa, então não me reportará às autoridades?
