The year is Universal Century 0083, and three years have passed after the One Year War ended with the Principality of Zeon's defeat. The Delaz Fleet, a group of Zeon remnants, launches an attack on the Earth Federation's Torrington Base, stealing the prototype Gundam GP02A "Physalis", a mobile suit with nuclear launch capability. Kou Uraki, a test pilot at Torrington Base, becomes the pilot for the Gundam GP01 "Zephyranthes", and joins the Pegasus-class carrier Albion as it pursues the stolen GP02A to stop the Delaz Fleet's ultimate goal: "Operation Stardust".
Each issues is a comic adaptation of one episode of the 13 episode OVA series.
