Plot
Medaka Kurokami, the recently elected Student Council President of Hakoniwa Academy, has instituted a suggestion box in order to collect suggestions and improvements from fellow academy students. Together with Zenkichi Hitoyoshi, she solves problems, from finding lost dogs to cleaning up club buildings and even fixing personalities. During the course of the series, Kouki Akune and Mogana Kikaijima are recruited to the student council to help improve the school.

Soon, the Student Council discovers the existence of the Flask Plan, supervised by the Hakoniwa principal in order to experiment on students with supernatural abilities dubbed as Abnormals. The goal of the project is to find a way to mass produce Abnormal beings. However, once a method is found, the students of Hakoniwa Academy will be forced to endure the vicious trial which will result in the death of most of the students. After battling many foes, the Student Council are able to put an end to the Flask project. However, the results of their success are short-lived with the immediate introduction of Misogi Kumagawa, a teenage boy with a powerful abnormality who plans on destroying the world. Using a school rule, he threatens to usurp Medaka's student council with one of his own by defeating her council in battle.
