WorldEnd: What Do You Do at the End of the World? Are You Busy? Will You Save Us?, Vol. 4

Tragedy repeats itself. With Chtholly now gone, Second Officer Willem Kmetsch and the faerie soldier Nephren have been swallowed by the darkness. Their tale should have ended here, and yet, all of a sudden, Willem hears a voice calling out to him. It's the voice of Almaria, a girl from Willem's past who died many years ago.

As scenes of an end long gone unfold before them, Willem and Nephren come to learn the truth about the organization known as True World......and in the black of night, a new Beast howls.
