Kidou Senshi Gundam II: Ai Senshi-hen

The year is Universal Century 0079. For nine months, war has been raging between the Earth Federation and the Principality of Zeon. On the space colony Green Noah at Side 7, the cluster of colonies farthest from the moon, the Federation has completed its new prototype mobile suits. However, the Zeon launch a surprise attack. In the midst of battle, fifteen-year-old Amuro Ray activates one of the Federation mobile suits, and from then on he defends his friends and the new assault carrier White Base from countless Zeon attacks as the war rages on around them.
