A hundred and ten years have passed since the Great War tore through the land. The Demon Lord was on the brink of winning when the Wrath of Heaven was unleashed upon him and on the world, ending the war. Its end was marked by the death of the Gods and the destruction of the world. With the world turned into wastelands filled with mutated and powerful monsters, vast deserts, and rogue, flesh-eating forests, it takes both wit and strength to survive in this new world.

Though 176 years old, Numia is young by human standards but she already knows her way through the lands filled with demons left from the Demon Lord's army and rogue Angels that destroyed any life they came across as well as the various tribes that jockeyed for power in this unforgiving land. While on a mission to recover a treasure, she came across an Angel and was forced to flee for her life. She nearly met her end when she fell into the mausoleum that contained the greatest calamity that befell the world in times long gone. In the silent dark, entombed in ancient ice and bound with chains meant to stop the very end itself, lay the Demon Lord.
