The sekaishu are everywhere, and people have been dying left and right—even Kuzaku and Setora. Why has the world turned out like this? Because of Merry? No. It's because of the No-Life King that took her place. And Haruhiro can't help but blame himself for all of it.
At least there's a light beyond the darkness: a reunion with the strongest volunteer soldiers. A new life will be conceived in the base where the survivors are gathering. The world may be falling apart, but this isn't the end yet. There may be a way to stop the devastation.
According to an old legend, a red star was once struck down by the primordial dragon, and its fragments became the black tumors known as the sekaishu that are infesting the world. This story may hold the key to saving Grimgar. It's time for friends to stand together and put an end to this threat once and for all.
