In the postapocalyptic Earth, humanity has reached the door of extinction. Earth's core has become unstable and split into two. The only hope are the two kingdoms Ranxus and Ruzone. These two kingdoms are keeping the unstable energies of the core at bay and preventing it from exploding. Secrets reveal that the core of the universe had become unstable. Unable to keep the evil spirit named Eraser of the core at bay, the good spirit of the core named Eternal had her soul split into 10 Star Runes and spread across the Universe. Eraser is set out to destroy those pieces and take control of the universe. One of those pieces has fallen on the planet Earth.
Eraser comes to know of it and sends her army of Xerkers to destroy it once and for all. The fate of the planet now rests in the hands of two siblings named Leo and Kate. But even that hope is about to be shattered. Kate, who has fallen under the control of Eraser, is leading the Xerkers to destroy Earth and the Star Rune. Meanwhile, Leo, who is also a Wingblade, must stop kate and save the planet. Will Kate, who is acting under the orders of Eraser, destroy Planet Earth? Or will Leo, along with his allies, save the planet and save his sister? A fated battle between the two siblings await.
