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...!
I forgot that I needed to stop by somewhere.
نسيتُ أنّ عليّ زيارة مكان
Hab ganz vergessen,
dass ich noch wohin muss.
Olvidé que debo hacer algo.
Olvidé que tenía algo que hacer.
J’avais oublié,
j’ai une course à faire.
Mi ero dimenticata
 di dover passare prima da un'altra parte.
Esqueci que tenho que parar em um lugar.
