Mobile Suit Gundam: The Origin

Universal Century 0068, Side 3 – The Autonomous Republic of Munzo. Zeon Zum Deikun, preaching the reformation of humanity through advancement into outer space, has been attempting to declare Munzo's complete independence from the Earth Federation government. Suddenly, he collapses and dies in the middle of a speech to the Diet. Upon Deikun's death, his aide Jimba Ral begins spreading conspiracy theories about the Zabi family. But despite his efforts, the Zabi family, led by Degwin Sodo Zabi, intensifies its secret maneuvering to seize control of Side 3. As we witness for the first time the untold chaotic history of the Universal Century, Casval and Artesia, Deikun's orphaned children, must face destinies just as tumultuous as the era itself.

Universal Century 0071. Three years have passed since the escape from Side 3's Autonomous Republic of Munzo. Casval and Artesia, the orphaned children of Zeon Zum Deikun, have fled to Earth along with Jimba Ral and taken refuge in the household of Teabolo Mass. They now live quiet lives under the names Édouard and Sayla. However, they are once again being targeted by the evil schemes of the pursuing Zabi family... Meanwhile, Side 3 has been renamed the Autonomous Republic of Zeon. The Zabi family have seized power, and as they consolidate their system of control, they embark on the development of a new weapon called the mobile worker in order to resist the Earth Federation Forces.
