Once a year the prestigious Rikkyouin High School has a lottery to determine the next year's Student Council membership. On their first day of school Chihiro Enomoto wins the presidency while his childhood friend Tokino Akiyama picks the vice-president's ticket. There is one catch though, they must first pass a one year apprenticeship under the current Student Council and failure to perform the tasks assigned, however minor, will result in immediate expulsion from the school.
