Advanced placement into a school of higher grade proof-reading is determined by the results of the Promotion Test strictly for class type. Ranging from A class with the best facilities anyone can offer all the way down to F Class which is composed of low dining tables, rotten tatami mats and other worn out facilities. Students can change classes by competing using the Examination Summons Battle system or ESB. Students summon characters with their equivalent test mark scores and use them to compete with other classes.
Akihisa Yoshii, now in his third year in high school, continues his misadventures with Yūji, Mizuki, and other high school friends. Akihisa, however, is enrolled in a rather unique high school. In Fumizuki Academy, all of the students are given avatars with fighting abilities whose power reflects the student's academic success. With their avatars by their side, our characters explore deeper into what it means to be a friend and how they treat each other and why. While Shoko, the school's #1 student, endlessly tries to woo Yūji, Minami and Mizuki try to capture the romantic attention of the oblivious Akihisa.
