Plot
The series follows Medaka Kurokami, a gifted, charismatic and attractive first-year Hakoniwa Academy student who is elected Student Council President with 98% of the vote. She institutes a suggestion box, and with the help of her childhood friend Zenkichi Hitoyoshi, addresses these requests in an unconventional manner. Over the course of the story, she distributes the student council leadership positions to other students such as Kouki Akune and Mogana Kikaijima.

The Student Council learns that the academy chairman intends to initiate the Flask Plan, a project to forcefully experiment on regular students, called Normals, in order to turn them into humans with superhuman abilities called Abnormals. The Student Council infiltrates the academy's secret lab and battles other students that are involved with the project.

Shortly after, 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. Medaka defeats him and disappears after stopping the moon from crashing towards the Earth, just to reappear in time for the year-end ceremony. Following her return, Medaka decides to leave the academy and assume her father's place ahead of her family's business conglomerate, the Kurokami Group, just to later return as the new chairwoman. Ten years later, Zenkichi, has worked his way up the Kurokami Group, becoming a high-level employee before reuniting with her, with both promising to get married after another fight.
