After a meteor hits Earth, traitor forces have (for all intents and purposes) taken over, and the people are suffering. In the chaos, a boy named Tetsuro Daiba, who had lost his parents in the meteor hit, is paid a visit by Mello, a mysterious woman appearing in a bright light. When Daiba comes to, he finds himself in a spaceship infirmary under observation. Stealing a fighter that he didn't know how to pilot (until he tried it), he breaks out, flying like a total pro. He was able to remember how to pilot from his DNA memory... and to find out more, his doctor friend takes him to his secret underground lab, in which he acts as a professor to find out ways to stop the traitor regime. When the forces invade to take him back, a girl named Rei Yuuki mysteriously shoots down their entire carrier with only a fighter jet! Apparently, both have mysterious powers that the enemies want, which may or may not be connected to their being the only two known survivors of the meteor impact. While looking for a third survivor (which turned out to be a cat), the two are taken by force to Queen Photon (ruler of the traitor regime), who claims that she is out to SAVE the Earth from those who sent the Meteor. The two don't know whether to believe her or Mello until the (telepathic) cat breaks them out of the Queen's sealed chamber, and Mello comes to straighten things out. That's when the two (er, three) of them make a choice... Stay on a planet that can't support their advanced race, or strike out into the unknown of space? (Source: ANN)

Two hundred years have passed since the hero Bartz and his companions saved the inhabitants of Planet R—a world where crystals control the natural elements—from the threat of Exdeath. However, agents of the wizard Ra Devil steal the crystals of Earth, Fire, and Water. With three of the four crystals in his possession, Ra Devil seeks to claim the Wind Crystal, the final piece he needs to summon the destructive god Deathgyunos. Novice summoner Linaly—a direct descendant of Bartz—lives with her grandfather Hassam. After receiving an ominous message about the Wind Crystal, Hassam travels to the Wind Temple. Concerned for his safety, Linaly suggests that they make the journey together. On their trip, they encounter Prettz, a rowdy yet amiable swordsman, who is captivated by the young girl and accompanies the duo for his own mysterious reasons. During a battle, an antlion monster injures Hassam, leaving him bedridden. As a result, the responsibility of securing the Wind Crystal falls on Linaly, with Prettz assuming the role of her guardian as they continue their perilous adventure.
