The party has suffered crushing losses attempting to flee the Ironblood Kingdom. Kuzaku was cut down by Jumbo, and Setora was feasted upon by the orc's great black eagle. No one had the power to prevent it. No one except the No-Life King, who has been sleeping inside of Merry. And with his awakening comes great upheaval.
Now, the sekaishu has overrun Grimgar, eating away at the world. In this chaotic situation, the Frontier Army, the volunteer soldiers, the various races that populate the land, and even people who ought to be dead all take action in order to survive and to achieve their own wishes. As the world is stained black, they each live out their own tales of adventure.
