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...!

Ya me estaba mentalizando para pasar
toda la noche aquí con Botan-chan.
