Plot
The plot follows Medaka Kurokami, a freshman student of Hakoniwa Academy. Medaka is elected Student Council President and institutes a suggestion box, for the students to make suggestions and requests. Together with her childhood friend Zenkichi Hitoyoshi, Medaka addresses these requests in an episodic manner. During the course of the story, Kouki Akune and Mogana Kikaijima join the Student Council. They soon learn the academy chairman intends to initiate the Flask Plan, a project to forcefully experiment on Normal students to turn them into Abnormals, humans with superhuman abilities. The Student Council infiltrates the academy's secret lab and battles with other students participating in the project to put an end to the Flask Plan. Later, the Student Council are challenged to a tournament by Misogi Kumagawa who wishes to replace Medaka's Student Council with one of his own. After Kumagawa's defeat, two students are unsealed from his powers and complete their transfer to Hakoniwa Academy. The two are more powerful than Abnormals and are dubbed "Not Equals". Their leader, Anshin'in, threatens to restart the Flask Plan once Medaka graduates, forcing the Student Council to train their successors. However, Anshin'in's true plan is to have Zenkichi usurp Medaka's position as Student Council President. Zenkichi does so on the pretense of improving the student life and succeeds. He convinces Medaka to allow the Flask Plan for those who are willing.

Relieved from her duties as president of the Student Council, Medaka soon becomes involved in a tournament to decide her husband. Medaka enters herself and becomes the victor, choosing to marry Zenkichi once they both graduate. Soon after, Zenkichi's close friend Hansode Shiranui leaves the academy. Medaka and Zenkichi discover she is to become the next host for Iihiko Shishime, a 5000 year old being, and set out to confront him.
