"I have researched the past, especially the phenomenon that came right after the alien invasion.
"500 years ago. A huge portal appeared on top of the Asura Palace. No one knew what kind of terrifying being was hidden inside that portal, but it was soon clear that everything inside was a being surpassing everyone's imagination.
"The aliens finally invaded our world. Asura Palace was fighting relentlessly, trying to stop them. Meanwhile, the aliens were fierce, but they relied heavily on their physical strength.
"Even though Asura Palace was a kingdom filled with madness, there were so many fierce warriors residing in this place. They killed aliens again and again, but no matter how many times they fought, the aliens would continue pouring into this world.
"The Asura himself fought fiercely against an alien of their race, which was soon known as a mature class warrior, and dragged the alien with him to the afterlife."
