One day, a mysterious male student named Rei Asami transfers to Hakuhodo Academy, a prestigious high school in Tokyo, from America. However, Rei is revealed to have been born in Saitama Prefecture. He leaves Hakuhodo and returns to Saitama, and forms a revolutionary movement to acquire respect and rights for Saitama citizens. Following him is Momomi Hakuhodo, the male president of the school's student council and the grandson of the school principal.
