Historia uczniów pewnej szkoły z oficjalnym podziałem na klasy mądrzejsze/głupsze oraz systemem Walk Egzaminacyjnych, dzięki któremu klasy gorsze mogą zamienić się miejscem w rankingu z klasami lepszymi.

* Based on a light novel series by Inoue Kenji with illustrations by Haga Yui.Fumizuki Academy is a school that strictly stratifies students, and the comforts of their classrooms, by test scores. The lowest ranked class, Class F, lead by Yoshii Akihisa, the idiot amongst idiots (and the series titular Baka) rallies to use experimental fantasy summoned monsters to battle the higher ranked classes for school supremacy.With the power of idiots and one of the smartest students in Fumizuki Academy, Himeji Mizuki, a girl who was sick on the day of the placement test and ended up in Class F together with Yoshii, one by one the other classes begin to fall before them.

The story centers around Akihisa Yoshii, the "baka" of the title. His academy rigidly divides up the student body into classes based on the results of tests. The prodigies are in the A class with reclining seats complete with air conditioning, but Akihisa is in F class, the lowest rung of the school ladder which is furnished only with low, decrepit tables and worn-out straw tatami mats. A girl named Mizuki Himeji is actually one of the smartest girls in Akihisa's sophomore year, but she had a fever on test day and was pigeonholed into the F class. Besides Mizuki (who Akihisa secretly adores), the F class also has Yuuji Sakamoto, the class president who has been Akihisa's friend and partner-in-crime since the freshman year. The school happens to have developed experiments to summon fantasy creatures, and Akihisa decides to rally F class to take on the higher-tiered classes and seize their perks. The F class uses the summoned creatures in an all-out battle for school supremacy.
