The world was destroyed, consumed by death and despair. And in the midst of it all, one man fought to the bitter end — the Sword God, Karselian Le Vandayan. But then, as if guided by fate, a door to another world opened. This time... it was Earth — a world that hadn’t yet collapsed. There, monsters have begun to quietly emerge, while humanity lives on, blissfully unaware of the impending catastrophe. This world hasn’t ended... But the moment they let their guard down, the nightmare will begin anew.
