Baka and Test

Plot
On the day of the placement test, Mizuki Himeji suffers from a fever and cannot complete it, and is thus given a score of zero, despite her intelligence. She is put into Class F, alongside the rest of the main characters - Akihisa Yoshii (the titular baka), Yuuji Sakamoto (the class representative), Hideyoshi Kinoshita (the bishōnen actor), Kouta Tsuchiya (the perverted photographer, sometimes known as Silent Ninja Pervert, Muttsurīni) and Minami Shimada (a transfer student from Germany who cannot read kanji.)

Akihisa is frustrated by the school's decision to place Himeji in Class F, believing she should've been given another chance at the placement test. He speaks to Yuuji, who also feels unfairly treated by the school's rigid system. They vow to prove to everyone that there's more to life than just test scores by taking down Class A and taking their classroom for themselves. This results in several Summoner Test Wars against higher-ranked classes. The show also loosely follows the love triangle consisting of Minami, Himeji and Akihisa, their crush. Meanwhile, Yuuji is targeted by Shouko Kirishima, a Yandere Class A student who fell in love with Yuuji when they were children.
