For hundreds of years, the universe has been controlled by two great powers competing to expand their territory with each other, namely the stone of darkness carried by the planet Orcus and the stone of light, which was the symbol of the planet Orion. The mission of expanding power eventually leads to planet earth– the final betting place and the seventh planet which was the culmination point in the war between the two great powers. Earth's character containing the compound elements Water and Air, a marriage of forces rarely found on other planets, prompted the fiery Orcus to conquer it. The earth-guardian families who inherited the power of the particle symbols of life, namely fire, earth, water, and air have experienced extinction. All done by the inhabitants of Orcus to make the Earth easy to reach, Edden's sacrifice through the fusion of the soul core alongside atmospheric particles to save the Earth. Meanwhile, Edden's disappearance through a huge explosion on his farm made Reagen wonder and found out about his father's current whereabouts. Inactive Reagen's power lay dormant inside of himself making him unable to access all the information that occurs in the universe. Regan's journey to find his father, which has gone through various dirty strategies carried out by Orcus fighters, made the starting point for the revival of air power that Reagen has. After Reagent's access was fully opened, along with the Lightstone warriors continued the father's struggle to protect the Earth.
