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. Tarok tries to lay low, hiding among people, but later meets the girl Tanya, who seems strangely familiar to him. Soon after, Tanya discovers a manifestation of extraordinary abilities that she did not even know about. The two of them begin to be pursued by a mysterious woman in a dark suit, whose motives remain unclear. Following her new acquaintance, the girl is drawn into a story, the scale of which she does not even suspect.
