Alfred Izuruha is a 10-year-old who lives in the neutral colony cluster of Side 6 and, like most boys his age, is obsessed with the war between the Earth Federation and the Principality of Zeon. Unbeknownst to him, Al's next-door neighbor, Christina, is the test pilot of a prototype Gundam being developed in secret by the Earth Federation in the colony. A Zeon Special Forces team is assembled and tasked with infiltrating the colony in order to either steal or destroy it.

When a skirmish breaks out between the Federation and infiltrating Zeon forces, the fascinated Alfred stumbles upon a Zaku mobile suit that has been shot down, piloted by Zeon rookie Bernard "Bernie" Wiseman. After this encounter, the two start a mutual friendship, so Alfred can learn more about the war that interests him so much, and Bernie can acquire inside information about the colony to aid his team's mission.
