Summary
Hearing a favorable review of Negi's his work a teacher from Shizuna, the principal considers promoting him to be an official teacher if he passes one more task: improve class 2-A's end of term exam result in order to prevent them from being the worst class of the year again.

Though Negi is determined to succeed in this assignment, he runs into a big problem: despite several of students being among the of highest ranks of the year, and majority are among upper average in rank, five of the students, consisting of Asuna, Ku Fei, Yue, Kaede, and Makie and collectively known as the Baka Rangers, are responsible in pulling the class' average grade down to the bottom.

After being stopped from using magic to increase his students' intellect and witnessing Asuna's determination to improve her grade, Negi decides to seal his magic for duration of the exam and help the his students by his own power.

Meanwhile, the girls overhear that the principal has planned to break up class 2-A should they score the lowest again, and those that perform terrible in the exam will be held back a year or even worse, send back to start over from the kindergartens. Believing that it is impossible to improve their grade within three days before the exam, the Baka Rangers, assisted by the Library Expeditions Club members, decide to go search for the legendary magic book that is capable of increasing the user's intelligence within the Library Island's underground, with Asuna bringing Negi along as their guardian should anything dangerous happens, though she soon becomes dismay after hearing that he wouldn't be able to provide them any magical assistance during their journey to unknown.
