Kurokami Medaka, a first-year student, is elected Student Council President. Her first act is to set up a suggestion box, which students later nickname the "Medaka Box." Medaka urges students to submit any problems to the box without hesitation, promising to handle any issue from anyone. Because Medaka won the Student Council elections with a staggering 98% of the vote, she becomes the Council's sole member. She asks her childhood friend, Hitoyoshi Zenkichi, for assistance, and he reluctantly agrees, taking the lowest rank in the Student Council. Soon, Medaka recruits two more members: former judo club member Akune Kouki as secretary, and current swim club member Kikaijima Mogana as treasurer, on loan for 300 yen a day. The Student Council members now spend their days resolving the problems submitted through the Medaka Box, whether they involve hooligans in clubs where they don't belong, girls needing help writing love letters, or people who have lost their pets, gradually earning the respect and admiration of the entire school.
