Japan, 1985, the Earth Defense Force Commander Ibuki has gathered his elite soldiers for a particularly harsh training session. After a day of brutal training these elites, fed up with Commander Ibuki, abandon the training only for the EDF to be attacked by the Great Star League Gozma. After conquering hundred of planets the Star League has set its sights on earth and sought to eradicate those who pose the greatest risk of interfering with their plans. Beaten but not broken these five elites refuse to back down from this threat. Just then the Earth begins to shake, and as Ibuki had planned, empowers these five with the Earth Force. Now enhanced with the power of mythological beasts and advanced military technology, the Blitzkrieg Squadron Changeman begin their war against Gozma.
