Following the collapse of the Republic of Zeon’s autonomy, the Earth Federation government declared an end to all wars. However, the absolute control exerted by the Earth Federation government has caused the system to decay. High-ranking Federation officials abuse their privileges and forcefully deport residents into outer space for speaking up against the government in a practice known as "Manhunting". The year is Universal Century 0105. In order to break the decayed system of the Federation, the secret society "Mufti" begins its operations.
