For thousands of years, the war of two galaxies has not stopped, because of which hundreds of planets have already suffered, and many worlds have completely turned into lifeless deserts. Tarok from the Gradarian race has been collecting intelligence for more than two hundred years while in the enemy's lair, until it was revealed. Trying to get away from his pursuers on an enemy spaceship, he is forced to land on a distant planet called "Earth," where he discovers a human race that seems to have never heard of any intergalactic war going on for thousands of years.
