The biggest name in Japanese science fiction—Gundam—returns with one of its creators retelling its origins 25 years after the series debuted. Caught in the crossfire of a space civil war, teenager Amuro Ray accidentally finds a new mobile weapon—the RX-78 Gundam.

In the ninth volume of Gundam: THE ORIGIN, the Earth Federation's White Base has now returned to space and is on the offensive. After long being chased around the solar system and across the Earth, they are on the hunt for what remains of the Zeon military establishment. Much has changed over the many weeks since the crew of the White Base fled to Jaburo with a prototype Mobile Suit on board, but now they have knowledge of who and what is awaiting them around the moon.
