Yamada Rikawa a young Mobile armor pilot stationed on the carrier Roosevelt was doing maintenance on his Mobius unit when he noticed two techs loading a large missile into the undercarriage of a mobile armor. Thinking nothing of it at the moment Yamada went back to work. His wing “man” for the attack was a young blue haired girl named Kumiko Hamano who would never stop talking, the only way he could shake her was by burying his head in the aft hatch of his Mobius unit.
Prepareing for the attack Zaft rookie pilots Malik Decardo, Franc Utall, and Shelba Ludecker were busy in the cockpits of their new Ginn mobile suits. Malik was a self-centered person with a bit of an arrogance problem, where as Franc was a bit of a show off. Shelba mostly kept to her self during briefings and training often typing away on here Ginns keyboard.

After 4 more days Shelba uncovers schematics for two more mobile suits at the Morgenroate. After pocketing the disk she attempts to leave the colony but the Le Cruset team attacks the port, She is forced to evacuate the colony in a life pod just before it collapses.
