After the Machine Gods killed the human race, I was transported to a fantasy world. The System was fading and weak. It did not have enough energy to give people Quests, Classes and Skills, and the Beast Tides ravaged the land. Civilization was struggling. The only way to gain magic was to hunt for cores, enslave monsters and perform profane rituals. Or do something that everyone thought was impossible. I did it. I forged an unbreakable bond, sacrificing everything to save an angel and a demon from a fate worse than death. Now we are in this together, trying to survive together in a world on the brink of annihilation. The System must be restored, and its secrets uncovered. Or else all will be lost to the monsters that roam the land.
