Kujibiki Unbalance(2006)

Kujibiki Unbalance is an anime series about a high school lottery with unexpected consequences. Each year, prestigious Rikkyouin High School holds a drawing to select its next Student Council. Chihiro Enomoto wins the presidency on his first day, while his childhood friend Tokino Akiyama draws the vice-president position. The catch: both must complete a grueling one-year apprenticeship under the current council. Any failure in their assigned tasks, no matter how small, means immediate expulsion from school. As Chihiro and Tokino navigate impossible challenges and office politics, they discover the lottery's true purpose goes deeper than simple selection. The series blends comedy with school drama as the pair struggles to survive their probation and prove themselves worthy of leadership.
