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...!
That's amazing! I get hurt all the time, too.
هذا مذهل، أتعرّضُ لجروح طوال الوقت أيضاً
Wie toll!
Ich verletze mich auch andauernd!
¡Genial! Yo también
me lastimo todo el tiempo.
¡Genial! Yo también me estoy 
haciendo daño continuamente.
Incroyable !
Che forza! Anche io mi faccio spesso male.
Isso é incrível! 
Eu também me machuco toda hora!
