It was first serialized in Futabasha's Super Robot Magazine from July 19, 2001, to September 19, 2003, compiling into three tankōbon volumes (two aizōban volumes by Futabasha) until its premature cancellation. Taking place 10 years after both Shin Getter Robo and Getter Robo Go, it follows a new Getter Team led by Hayato to stop the invasion of the Andromeda Stellaration from invading Earth using the new mecha, Getter Robo Arc.
