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.
