Kurokami Medaka is perfect in anything she tries to do – be it sports, exams or anything else. When she ran for Student Council President, she managed to gain 98% of the votes, promising to solve everyone’s problems, 24/7, through the suggestion box that she implemented. Because no-one can match her standards, Medaka runs a one-man Student Council, and so she asks her childhood friend Hitoyoshi Zenkichi to join her, but he isn’t interested. To change his mind, Medaka brings Zenkichi along when solving her first request – to deal with the third-years that have taken over the kendo hall.

A second-year, Ariake-senpai requests the Student Council’s aid for solving the problem of a threat she found in her sports locker along with a ruined set of spikes. Medaka immediately deduces the culprit down to everything but their name from just the letter and the state of the shoes, and goes down to the sports field to catch the culprit. After being outrun by Medaka, Isahaya-senpai denies having touched Ariake’s spikes or making the note, but Medaka believes her immediately, dropping the matter. Feeling guilty, Isahaya takes Ariake’s trainers and replaces them with a brand-new set of spikes and an apology note. When Zenkichi is asked to complete a request to find a lost puppy, he miserably fails after finding out the puppy had grown into a much bigger dog. Medaka helps him out, only for Shiranui to find out that while Medaka loves animals, animals don’t love her for some reason, with the dog fleeing from her and hiding behind Zenkichi.

Zenkichi has been going round to all the clubs for their trial period even though he’s already a Student Council member, earning him the nickname “Club Crasher”. After dealing with a small-time group trying to rebel against Medaka, the Student Council gets a request from the judo club to help them pick a new captain, where Zenkichi and Medaka see a familiar face: the “Prince of Judo”, Akune Kouki.

Zenkichi and Akune begin their match, and Akune quickly gains the advantage with 9 points out of a required 10, while Zenkichi hasn’t managed to get his required 1 point yet. Once Medaka encourages him, Zenkichi manages to win a point against Akune, and gets to stay in the Student Council. Because they can’t have a “prince” stronger than the new captain, Nekomi-senpai kicks Akune out of the judo club, and he goes to the student council, where he gets his first assignment – to help a senior write a love letter.

The Student Council realize they have a budget problem due to having no Treasurer, and decides to hold a competition in the rarely used swimming pool to decide which club will get extra funds. Boys are to be handicapped by giving them floats, with the first game being a water based version of ball-basket, in which clubs have to get 20 balls from the bottom of the pool and throw them into the corresponding basket.
