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.

You Sato is a new high school student living in the dorms. While seeking cheap eats at the local market he finds himself beat up and semi-conscious with fleeting glimpses of a girl during the moments of his collapse. As his memories recover the next day, he discovers that trying to purchase half priced lunchboxes can be hazardous to his health as free-for-all fights with local students for the discounted food is the nightly routine. The girl from the night before, Sen Yarizui, is an upper classmate known as the Frozen Witch and is one of the local Wolves who dominates the area. She educates him on the rules of the game where Wolves eat well while Dogs settle for cup ramen. With fellow first year student Hana Oshiroi, a fetishistic germaphobe, You Sato sets out to discover if he too has what it takes to be a Wolf and taste the sweet victory of half priced boxed banquets or wallow in the bitter defeat of reconstituted noodles and salty broth in a styrofoam bowl.
Yūki Ōjima attends Takafuji Private Academy, a large school with over 6,000 students, where he is a member of the Food Research Club along with seven others, including his childhood friend Chisato Sumiyoshi.

When the election for the next student council president comes up, the front runner Satsuki Shinonome proposes that clubs which have no merit should be sorted out and abolished. The Food Research Club seeks advice from the current student council president, Yakumo Mōri, who suggests that Yūki run in the election as an opposing candidate. Yūki learns about the issues facing the school and decides to run in the election.
With beautiful assistant Sahoto Ashisu aside, mangaka (and cherry boy) Yūki Aito can hardly concentrate on his works, forcing his managing editior Mihari Otosuna to push him (physically) meeting the deadline. With new busty but ditsy Rinna Fuwa and skilled but money-loving Sena Kuroi joining the assistant pool, Yūki's life is more like a harem than a manga studio.
