A planet outside the Milky way has been invaded by the men of ‘General Scorch’ for many years. One day, the army protecting the planet was finally defeated by ‘General Scorch’. The military base of the whole planet was occupied by the enemy, and many robots began to destroy the planet. When the leader of the base recognized the defeated message, he immediately released warships to let all the indigenous groups leave the planet and told the rebels who had been in contact to seek assistance. After receiving the news, the rebels sent the two strongest pilots (Natzski and Renza) to help the residents board the warships.
